In modern computer systems, the biggest bottleneck of information tends to be in communicating with the hard disks. High seek times and relatively slow transmission rates when compared to RAM speeds can add up quickly. This was a necessary evil back when RAM space and costs were at a premium, but now it is not uncommon to see 4GB of RAM on laptops, and even 12GB on desktops. For users whose primary computer use is browsing the internet (either for work, writing articles, or lolcats) and have some extra RAM, moving the browser cache to the RAM from the hard disk is a definite option for increasing speed.
In Linux systems (specifically Fedora and Ubuntu systems), this can be achieved for Chrome and Firefox by creating a larger ramdisk, mounting the ramdisk after boot, and then setting the browser of choice to use that ramdisk as a cache. The necessary commands to do this are
readily available
(
internet archive
) on the internet, which makes life easy. Using ramdisks for performance boosts are not exclusive to browsers, and can be used for other software such as
Nagios
for example.
We have previously covered a tool called
Espérance DV
for moving cache to RAM in Mac OSX, and for any Windows users feeling left out, there are ways of making Firefox
bend to your will
. Obviously you will see an increase in RAM use (duh), but this shouldn’t be a problem unless you are running out of free RAM on your system. Remember, free RAM is wasted RAM.

If it has to read the browsers code from disk because it does not have enough RAM to hold it all in it’s cache then it could be a little counter productive.",

Get a modern browser like Chrome or Safari instead.The performance problem with Firefox on Linux is mostly because it uses SQLite and sync() calls that force it to flush the disk cache and wait until done. It’s not obvious on Windows because Windows fakes the sync() calls. That improves performance but means you have no actual guarantee of data integrity on Windows. Putting the files in RAM subverts the data integrity checks and makes Linux emulate Windows, favoring speed over data integrity. Firefox also has other legacy single threaded chokepoints.The performance problem on Windows is primarilty that the OS has fractional RAM allocation by design and many apps still have 32 bit limits. You may have 16G of RAM and Windows 7 64 bit but if you’re using a 32 bit browser it can only get 2G of RAM and Windows will automatically try to page part of that out to disk. Creating a RAM disk as another process with it’s own RAM and helps keep that data in RAM instead of on the drive. Similar limits happen when people run the 32 bit version of Firefox on 64 bit Linux so they can run 32 bit plug-ins like Flash. Even though you have 16G of RAM, using the 32 bit Flash in the 32 bit browser limits it to 2G of RAM.Obvious solutions to these problems are to avoid legacy single threaded and 32 bit programs like Firefox & Flash. Those codebases will die off eventually. They were useful in their day but they are the past.",

Halloween Hangover: Talking Heads

Here’s a Halloween prop leftover; [Chris] built
his own version of singing heads
from Disney’s Haunted Mansion on his porch for last year’s ghoulish decor. A projected image of actors singing a spooky song gives each of the four Styrofoam mannequin noggins its own digital life. There’s an optical sensor on the porch stairs that is tripped by unsuspecting candy-seekers. An Arduino monitors the sensor and uses AutoHotkey to start the video clip on a netbook. Check out the video after the break to see the finished display do its thing after dark.

Outside-air Cooled PC

[Brian] came up with an interesting PC cooling setup. He lives up north where it’s chilly in the winter. Using a bit of dryer ductwork and he was able to harness the outside air to cool his box. The system uses a window insert along with a dryer hood to suck in the outside air with a PC fan. We hope the air is adequately warmed, as it is exhausted into the room. Join us after the break for more pictures of his setup.
Below are the duct fitting he used. This includes a hood for outside, a damper which closes with gravity, some scotch brite pad to act as a filter, a flexible duct, and a quick connect.
The next three images show the construction of the window insert. The filter and hood are on the outside of the board, and the quick connect on the inside. Although [Brian] shows a damper in his parts image, we’re not sure where that is actually installed. We think it would be best for this damper to have a servo actuator, as gravity won’t be enough to keep the wind from forcing it open.

You could also do like one fellow did out there on the interwebs and put a vehicle radiator onto the water cooling system and have that stuck out the window as well, with a fan on it to focus the cold air onto the radiator itself. In my area that means you need to use a liquid that cannot freeze at temperatures of -50C or lower.http://gyazo.com/94bdc6146d5739d78d28bb8465e75ad1That link shows the temperature without windchill for Watrous, Saskatchewan which is pretty close to where i live. It was actually colder that day in my immediate area due to being more out in the country with less wind breaks and such. Cities/towns are naturally warmer due to the many buildings and streets.Do the whole system right, and you could have a wickedly cold system.However, like i said in another reply, Just put a dehumidifier inline between your air source and the computers intake fan, and you will have solved a good 85-100% of the humidity issue. The air might get a little warmer, but if the dehumidifier has a cool air setting, it can cool down the air again and keep it’s humidity near zero. I.e Cold dry air.For the air source though, i recommend putting a steel enclosure around the air intake, so as to keep snow and other moisture as limited as possible. Done properly, and it should help lower the relative humidity as well, before it even reaches the dehumidifier.Another person, Fileark, mentioned a bit about how the temperature defines just how much actual moisture is in the air. It might be 100% humidity in -40C temperatures, but in +15C or so, that only comes out to being maybe 10% or higher for humidity. Anything below 50% humidity is supposed to be normal standards, so your computer should be able to handle that just fine, especially with a filter or two in place to catch the possible extra moisture and debree that Might be in the air.All in all, the advice on the web page is not bad advice per say, but rather it is incomplete.",

But that’s about it.I solved my cooling problems by just hanging my home server relatively naked on the living room wall. Way better than any halfway normal case and the power usage slightly heats the room ;)",

If you bring in cold air to cool your PC, you will lose warm air somewhere else in the house unless you are pressurizing your house with the extra air. It takes energy/money to warm up that cold air. You can argue that the heat energy from the computer is waste heat that needs to be dissipated. But I would argue that the waste heat would be put to better use to warm the room/house. If you actually need the extra cooling, ie the computer will not work unless you cool it below room ambient temperature, that is a dodgy setup. What will you do during the summer months? Use an air conditioner to cool your computer?",

Since temperatures outside tend to move rather slowly (a few degrees/h perhaps) I just can’t see that happening, though no one can really say definitively either way without making a detailed thermal model of the entire system.Either state your idea as a competing theory or do a proper analysis of the big picture before before accusing others of making ill-formed statements.",

However, the heat loss from the un-insulated ducting and window adapter will add loads to the heat bill. Then if the wind is blowing you will have plenty of cold air blowing through the case into the room as well. I guess if your renting, and not paying for the heat, you don’t care.I don’t think condensation is a major issue because he is heating, not cooling the air. Cold air can not hold as much humidity (water vapor) as warm air If there is condensation it will likely be, mostly, on the outside of the case where the warm air strikes the cooler case surface. Now if you turn the fan off, and warm humid air migrates quickly into the case then there may be trouble.I like the idea to cool a computer using the cold air from outside, but I would opt to use insulated ducting, insulate the case, and exahst the air back to the outside if I were going to build something like this.My method is a bit simpler. I have a server closet and pull filtered air from the crawl space into the closet and force the hot air out through a roof vent. I can keep the closet closed and keep the heat load to a minimum year round. (Typlically even in the summer the crawl space temp is less than 70F",

DIY Air Gap Flash Saves At Least Seven Grand

Did you know that a standard camera flash is much too slow to capture high quality images of bullets? A relatively long flash duration results in blurred images of the bullet. By building
this air gap flash a bullet can be frozen in mid-air
, producing some stunning results. There is an element of danger here, and not from the bullet. This flash uses a 35,000 volt capacitor to produce the mini-bolt of lightning which serves as the light source. The unit can be built for a few hundred dollars, which sounds like a heck of a deal if commercial models really do start at $8k and go up from there.
Now that the photographer has a super-fast flash,
a camera axe
takes care of the timing… which is everything.

"content": "@MauriceExcellent work. Is the HV supply just a diode/capacitor ladder? In the pictures it looked nothing like the kit you linked to.@SporkThat works to a degree, but you have to deal with the blur of the shutter. Physical shutters work, usually, with two moving curtains. One moves and starts exposing the sensor or film, the other follows it and blocks light. The sync speed of the camera is the speed that the camera has the front curtain fully open, and the sensor/film fully exposed, before the rear curtain starts closing, usually around 1/60s to 1/250s. To get a faster shutter speed, the rear curtain begins closing before the front curtain gets fully open; you still get a lag of about the sync speed from the image captured on the left of the frame to that on the right. If the bullet happened to travel at the same speed as the shutter, you might even have a more blurry picture.Fully digital shutters can work completely differently. With the right sensor and shutter combination, you wouldn’t need a strobe light. But last I priced those, they were more than seven grand.",

555 Based AM Radio Transmitter

Bust out that 555 timer and use it to
build your own AM radio transmitter
. The circuit that [Rtty21] is using only needs the timer chip, an NPN transistor, three caps, three resistors, and a potentiometer. It generates an amplitude modulation signal around the 600 kHz range which you will be able to pick up with any normal AM radio. From the comments on the article it seems you’ll get around 30-40 feet of range out of the device. We don’t see this as a competitor for
the FM spy microphone
, but maybe you can use it as a diy baby monitor.

"content": "@Th3_uN1Qu3I second your comment. This “design” is so wrong in so many aspects, that just using it because it “does someting” (?!?) is very wrong.-based on stated component values, it actually oscilates at arround 60kHz. What they hear on the receiver side are harmonics.The “good” thing is that it’s easy to find it on AM radi scale (as it will show up every 60kHz, the bad thing is that it’s designed to mess up with everything nearby that requires reception.I wouldn’t be surprised if some of (very high) harmonics messes up a nearby wireless (phone, ethernet, …).-The transmiter side with transistor that has only collector and base connected, is probably the bast part of this design (sic) – it does not work at all so it limits all the negative aspects mentioned above :)If you relay want to messup with this “modulator/transmiter), add resistor leading to the base (1k will do it), add resistor in the collector circuit (depending on transistor, something in 100 Ohm range would do it), connect emoter to the GND (negative suply), and then connect antena (long wire, or wire or coil of any kind) to collector. I bet that will extend the range and mess up with more devices :)-another “improvement would be to raise the frequency so you end up using lower harmonic that carries more energy. The frequency is controlled by R1, P1, R3, and C1 (seehttp://www.royalrife.com/555_calculator.html), and just changing R3 to 1k, or C1 to 100pF, you’ll get to AM band and use the first harmonic (the one that has highest “energy”But the best advice would be to google a bit and find a REAL, simple, equally cheap, AM transmiter.Radio amaters usually refer to them as QRP, might help in your search.",

I don’t think anyone in their right mind would use this very weak transmitter for any real world applications. It’s one of those disposable projects. It’s a cute DIY project and not much more. Nor will it be taught in universities as an example of sound RF circuit design.The person behind the hack is a 15-years-old trying to have some fun who took the time to re purpose the 555 for an interesting application and in the process it motivated so many to build their first RF transmitter ever. That’s the real story.The beauty of this hack is also in its ease of replication. This has its appeal for the entry level hacker. If this design works in getting more people to roll their sleeves and do something and hopefully get it to work then that’s wonderful. For many people, the first step is the most difficult one. If such a simple project can get people motivated, and if it builds their self-confidence, then it’s a great project.And that’s enough to get it honorable mention.You should see the numberof views on the kid’s Instructable page. It’s massive. And the number of folks who tried it is impressive too. I am sure they will quickly realize that it’s a cute project but not very useful from a practical point of view. They will then look for more complex projects and would want to understand the nuts and bolts of AM/FM transmission and so on.I built it in a couple of hours but I ended up spending a couple of days after that just reading comments and suggestions of how to make a better AM/FM transmitter. So this 555 transmitter is no masterpiece of science but it’s a masterpiece for easing newbies such as myself into reading and learning more about radio communication.So the kid who published this Instructable deserves the proverbial pat on the back for being a great motivator.",

We’re not sure where the fascination to have your libations flung at you came from, but we can’t say we’re entirely against it. This
beer catapult robot
(dead link try
Internet Archive
) will pull a cold one from its gullet and fling it to you, or in your general direction. While he doesn’t have the source code available for the Arduino bit, we’re OK with that. We’re more interested in the mechanisms at work here and there are plenty of pictures of his set up. It seems very similar in design to
this one we covered back in 2007
, which also appeared on” The Late Show with David Letterman”. Join us after the break to see the thing in action.
[thanks Springuin]

Cans let in less light and typically have less empty space that exposes the unopened beer to air. They also are lighter (cheaper) to transport. The brewing industry uses bottles to convince the consumer that the beverage within is classier than what can be found in cans, typically by way of the ancient myth that cans will impart a metallic taste. Bull again. Cans are lined with a polymer that keeps this from happening; the beer isn’t touching metal. My local microbrewery uses cans and kegs (both made out of recycled aluminum) exclusively for distribution.Cool launcher.",

Reverse Geocache Features UI And Is Reprogrammable

Here is yet another offering in the Reverse Geocache puzzle arena. We’ve been getting a lot of tips about these projects but
this one in particular stuck out from the others
. [Mure] packed in a bunch of features, starting with the LCD screen seen above. You can just make out the single red button near the bottom of the image which is used to traverse the menu. The octagonal box has an octagonal PCB inside that includes a USB connector. As you can see in the video after the break, this can be used for charging the batteries, and communicating with the internals. An accompanying program is used to generate puzzle data, which can then be programmed via that USB connection to set a new puzzle location. This functionality certainly protects against accidental lock-outs which were a problem with
the last puzzle we looked in on

If you’ve ever thought of utilizing a small and inexpensive OLED display in your project [Rossum] has
the details you need to get started
. In the past we’ve seen him take
a tour of available LCD screens
and this is much the same, detailing his look at three different models. In the video after the break each is connected to a driver board that he made. The boards have two important components, the first is a boost driver for the 12-16V input the screens need, the second is an octal buffer necessary if you are using a 5V microcontroller. These take care of the hardware considerations, making it simple to drive them with a chip of your choosing.

Data Logging Football

[Ben Kokes] threw together
a hardware package to capture data from a football
. In the center of a Nerf football he made room for an accelerometer, gyroscope, and an electronic compass. All three can capture 3-axis data and, along with the LEDs ringing the circumference, they’ve controlled by an XMEGA192 microcontroller.
This makes us think back to a time when baseballs with a built-in speed sensor first hit the market… does this hack have mass marketing potential? Perhaps, but only if the $225 sensor price tag were greatly reduced. When we first started reading the description we hoped that [Ben] had coded an interpreter that would render 3D playback video from the data. He hasn’t done that, but from the data graphs he did assemble we don’t think that functionality is out of the question. We’ll keep our fingers crossed.

Steam Cycle Feels Like Your Pants Are On Fire

Usually we don’t like to feature projects that have zero build details, saving them instead for
a links post
. But this
steam-powered bicycle
is too… peculiar to pass up. In between the rider’s legs is the
firebox
that contains a wood-fueled fire. Watch the clip after the break and you’ll find just how noisy this contraption can be. In addition to the mid-range “chug-a chug-a” there’s also the constant whistle we’d attribute to the pressure regulator. It’s surprising that the whole bike doesn’t heat up, but it must not be all that bad since the test pilot isn’t wearing asbestos pants. All kidding aside, it looks like this beast has no problem getting up to a running pace (based on the movements of the camera) and that’s thanks to a renewable energy source.
We’d be much more comfortable seeing this in
a mechanized tandem
form factor since we just can’t get over having a fire between our legs.

It’s not like we have this huge tree overpopulation problem. Trees aren’t very fast runners so I think we can take them.If you grown another tree to replace the one you burned, you basically break even (neglecting efficiency losses, which are not negligible). Combine that with the fact that it takes many years to grow a tree, and only a few minutes to cut one down and burn it, and you quickly see how we’ve reached the state we’re in now. It’s not a steady-state system, but rather one that is being pushed to imbalance.Respek Mother Earth, my brothers!",

In areas where slash/burn agriculture is the norm (Brazil, etc.), there is generally a net loss of forested area as it is cleared away for other purposes. I think we can all agree this is a Bad Thing.Where sustainable forestry is practiced (generally North America, Europe), forests are essentially treated like giant crops on decades-long rotations and are re-planted after they are logged. Additionally, other management techniques (thinning, brush clearing, controlled burns) are used to ensure that trees grow healthier and stronger than if the forest were left to grow alone. In this case humans aren’t merely taking advantage of nature, we’re being stewards as well.I might be a bit biased here, I’m from a family of foresters/loggers.

Un-tethered electric transportation is dead in the water, marketing it to hippies aside.And “green”-wise, by the time you add up the materials consumed and toxins released to build an electric bike, and to generate the electricity to run it (here’s a good one, it still takes more energy to refine the silicon to build a solar cell than it will generate in its lifespan, unless installed in a desert and run as part of a utility array), it is much more efficient to build this steam bike out of scrap and run it on wood that renews itself with the power of the sun.Or you could run it on scrap paper/wood, god knows we have enough of that! A nice pellet fired boiler and this would burn clean and probably generate twice the BTU – and that’s sawdust that’s left over from mills. We use it for heating a lot around here.@Mike: excess water vapor? you must be joking or trolling. Do you know how much water vapor comes off any body of water when the sun is out?

PIC Spectrum Analyzer Uses Fast Fourier Transform Routine

[Simon Inns] just rolled out his latest project,
a PIC based spectrum analyzer
. He’s using a
Fast Fourier Transform
routine crafted in C to run as efficiently as possible on the 8-bit chip. The video after the break shows that the results are quite pleasing, with just a bit of noticeable lag between the sound and the waveform representation on the graphic LCD. We found his notes about using an audio amplifier chip to be interesting. He utilizes the properties of an LM386 to move the input signals from a range of -0.5V to +0.5V into a very ADC friendly range of 0-5V.

I’d wouldn’t be suprised if pruning only leads to a 1% reduction in calculations if only the top bins (that are complex conjugates of other bins) are thrown out. I don’t know how much the DHT would save in comparison to the FFT.The square root routine probably could be chopped to be just real^2+imag^2 as only the visual output matters in the end. The tables used for the linear scale and log scale output would have to be updated to reflect this change.

In fact, the wavelet transform has less complexity, O(n), than an FFT, O(n log2(n). The execution time, though, depends upon the length of the wavelet functions used. They are, effectively, half-band finite impulse response filters. Do a Google search on wavelets and you’ll find a lot of material out there, including source code, libraries, and programs.",

[Zach] enjoys playing the game Catch Phrase, but the complexity of the words makes this game a no-go for the little ones. We remember that the game used to be mechanical, using paper disks with the words on them. Those would be easy to recreate with your own dictionary set, but since it has transitioned to an electronic unit that option is out the window. So [Zach]
decided to build his own version of the game
that lets you use custom word sets after drawing inspiration from
another Catch Phrase hack
.
He’s calling it AVRphrase since it uses an AVR ATmega328. You’ll also find five buttons, a piezo buzzer, and a character LCD included in the design. He saw the project all the way through to the end, having a PCB manufactured, and installing it in a project box. A demonstration of the finished game can be seen after the break. [Zach] ended up with 9 working units at a cost of about $30 each.

So you manged to get a great deal on a fake tree during the after Christmas sales, but what should you do with your old one? If it was lighted with fiber optics you can reuse the strands to
create your own star map
. [Mr Trick] shows how to disassemble one of these trees, grouping the fibers by length. He built a wood frame, then covered it with a layer of cardboard and another of black fabric. From there the painstaking process of routing the fibers in a way to looks convincing starts.[Mr Trick’s] final product uses multiple LED light sources and even includes RF control.
Think this project is large and time-consuming? Check out
the same idea built into a bedroom ceiling

IPhone Tilt Motion Controller

Here’s a mounting system that adds
mechanical tilt control to the iPhone
(link dead, try
the Internet Archive version
). It uses two servo motors to rotate along the X and Y axes. An analog joystick is used along with an Arduino to control the movement of the apparatus. As you can see in the video after the break, this works quite well when playing accelerometer-based games. But adding a joystick isn’t the end-goal of the project. [Shane] plans to point a camera at the iPhone and use image recognition to play games automatically. That sounds like a big bite the chew but
we’ve seen this work with Guitar Hero
so we’re optimistic.

A Look Back At DefCon 18 Badges

As he does every year, [Joe Grand] gave
a talk explaining the development process for Defcon 18 badges
. We looked in on these when
details started trickling out back in July
. They feature a neat bit of tech in the form of an LCD that acts much like ePaper. It doesn’t take any electricity to hold the image, only to change the display. This is a valuable feature for a battery powered device and allowed him to get about 9 days of juice out of a CR2032. This year’s badges also used laser-etched Aluminum as a substrate.
We’ve embedded the talk after the break and found it interesting enough to watch the entire hour. If you’re more interested in the hacks that came out of the badge, we’ve put together
a playlist of videos
[Joe] took while at the conference.
[Joe Grand] starts about nine minutes into the video

[Chris] was unhappy with the battery performance of his Rovio. It seems that he’s not alone, so he set out to reverse engineer the battery charging circuit to see if there was a fix. Boy is there,
what he found
is the diode above, apparently installed backwards when compared to the silk screen diode symbol. Now it’s entirely possible that the silk screen is wrong and this was fixed during assembly. We think that’s unlikely because if the closer of the two diodes was supposed to have the same polarity as the one next to it there should have been room to install them both in exactly the same orientation. [Chris] pulled out a soldering iron and changed the diode to match the silk screen. That fixed his problem and he’s now getting better performance than he ever has.

CES is a time for showcasing the latest and greatest innovative products. While the crowd milled around the iLounge there was one company who stood out amongst the rest. [Mike] from CableJive is making his debut on the biggest stage for innovation this year. Many of you will remember [Mike] from a post back in 2006, where he was fed up of with all of the good docks being for the apple products exclusively. He set out to fix this and, when talking with him, attributes his success to the
coverage Hack a Day did on his project
. CableJive has become so popular that he has hired staff that help him produce his products. All detailed information for their products can be found at their
website
. The finished product is displayed after the break.

Ten years ago we were ready for true HiFi sound from a digital source, but the industry decided because people were burning CD’s to pull hi def and beef up it’s security. Meanwhile Napster and this little white crap took over. Urinals! Then the raid on the record stores and down came the house of HiFi. Now it is official, combined music sales are falling. Music is just noise and artists aren’t needed, just a beat machine, bass, and babble. I hacked my first dummy head mic 35 years ago. Live recordings on cassette in binaural are incredible, not possible on CD. The top third of the audio spectrum in wav is “pixelated”. At the end of this month I will make my first Hi Def recording of our local 17 piece swing band. The first and only CD recording I made of them, was full of snass. Snass is my description of the pixels of sound that ride on top of the CD. So anything worse ain’t progress. Wake up it’s twenty eleven. PROGRESS YEAH!",

A fresh pot of coffee is never more than a tweet away with
the Tweet-a-Pot
. It works in much the same way that
our Troll Sniffing Rat
does. For that build we used a Python script to monitor our comments, and this does the same except that the script read tweets through the Twitter API. It watches for a specific hash tag (#driptwit) and when found it sends a serial command to an Arduino. The microcontroller then writes a digital pin high to actuate a relay, powering up the coffee maker.
Sure, you have to preload the pot with grounds and water, but what do you expect,
automatic coffee roasting
and
brewing
? That’s quite a bit more work.

With the
Pre-CES Keynote
made by [Steve Ballmer], the announcement came that the next iteration of their operating system being available in SOC specific form. This will lead to windows being able to run a very diverse hardware set in a much more efficient manner than it does right now. Microsoft displayed 4 different versions of what the next generation prototypes are from 4 different manufacturers but there has been no work done yet on the GUI for SOC as [Ballmer] was very clear to mention that more than a couple of times. Some photos of the prototypes can be found after the break!
The picture below is Intel’s iteration of System on a Chip.
These next three photos are from Snapdragon, Texas Instruments OMAP and Nvidia’s Tegra Platform all using an ARM processor:

However we should not forget they are late to the game. Things that people need windows for, like gaming etc, will take a long long time to migrate (if they migrate at all) to this “new” arch and will probably not benefit from the change.I understand Microsoft wants the share that is now becoming Apple’s, that is, Joe Six pack. I’m not saying OSX doesn’t have instructed users, in fact most of students I see now a days use OSX. What I’m saying is that operating systems with limited functionality is the “new thing” and Microsoft wants to go that way. I don’t blame them when they own the worst security icon. In fact, the user itself is the main door for insecurity. Limiting user choices happens to increase security :)From what I can tell, Microsoft is stepping away from the traditional desktop as we know it. Apple already started the change quite some time ago with the introduction of cloud services and a App store model which very recently got integrated into OSX.As dedicated Linux user I’m quite comfortable with this new move which will leave the traditional desktops to be ruled by unencumbered, and hackable operating systems. I really wish I’ll be able to assist to a severe decline of Microsoft’s monopoly in the desktop.",

The majority of the work would be providing the tools to config and build to the required platform.Also worth noting that the average SoC contains a couple of processors and DSPs and/or HW IP blocks. For example the TV/STB SoCs I design contain a main application processor ( running linux ) and two other platform processors ( running RTOS like uCos, Nucleus+ etc ). So Windows would only be doing application level software on the SoC, the other platform level software interfacing with the SoC specific HW would definitely not be running Windows.MIPS ( 74k, 24k ) is also pretty in the SoC world along with ARM so you have to wonder if MS will also do a MIPS port?‘flush flushMr T.",

Hacking A Hack: Electric Hybrid Geo Metro

[Ben Nelson]
turned his electric Geo Metro into a plug-in hybrid
. But wait, where’d he get an electric Geo Metro? It seems that we’re one hack behind [Ben], who
converted the vehicle to all electric
back in 2008 using a forklift motor and some batteries. This time around he’s following the
Chevrolet Volt’s
example by adding a backup generator. Instead of going with a gasoline power he added a tank of propane and the generator from a Recreational Vehicle. This won’t put out enough juice to drive while the generator is running, but you can use it to extend your traveling range by pulling over for a nap while it tops off the batteries.

Chances are anything bought at Home Depot will be have one or both crappy parts because the quality companies just can’t compete with the cheaply made knock-offs on retail shelfs.

You should do your homework on the quality of the brand for the price, and check to make sure there are local service centers in your area.Now here’s another more interesting point on the project.

These valves are used for safety purposes since the tanks are made so cheaply.I’ve had situations where a tank was going into relief while I was transporting the tank to/from a refill station.

There are stricter regulations against diesel engines in the US, so many foreign cars can’t be sold here. With this and the recent low-sulfur requirement, diesel fuel is more expensive than gasoline, so even with better MPG it sometimes costs you just as much in the end. The cars end up costing more too because the auto manufacturers have to put in the extra emissions controls. Don’t blame the oil producers, blame the environmentalists. (not that I think regulation is a bad thing)I like this hack for a pickup where the fuel and generator can be mounted external to the passenger compartment.

Thousands of Euros must be spent in long certification processes and tests to have your converted vehicle street-legal. And of course, you have to carry it in a trailer to those places. Some even suggested that is cheaper/faster to put your car in a trailer, drive it to Germany (!), certify it there, and bring it back.Bad times for Spanish hackers.To make this worse, here, in no case you would be able to (legally) run your car on fuel if you don’t buy it from an gas/LPG station. Automotive fuels have special taxes you pay when you buy it in a gas station. For example Diesel for heating is way cheaper than Diesel for trucks or cars, even if it’s the same liquid. Moreover, using heating diesel for your car constitutes tax evasion and you would probably go to jail if caught.Nice hacked hack by the way!",

Then divide the diesel’s MPG value by 1.11 to account for 11% higher energy density of diesel.All other things being equal, a diesel vehicle will still come out ahead (due to higher efficiency of the diesel cycle vs the carnot cycle), but not as far ahead as you might think at first glance.I find all the talk about napping while running a generator in the car funny since I don’t see “napping” mentioned anywhere in the original article, nor do I think it would be most people’s inclination to nap next to something as noisy as a running generator. Nor would most people want to drive with a noisy generator running in the car (especially someone accustomed to driving an EV which is otherwise so silent).The value I see in the generator is being able to park somewhere, turn on the generator, go do something else, come back and have your batteries fully charged.

They seemed like a great deal, until you realized you have to pay road tax. You’ll register your vehicle as an alternative fuel vehicle, and pay yearly taxes based on the mileage you traveled in every single state.So to be legal, this guy has to record mileage in every state he goes to, then pay that state whatever their road tax is per mile. Note that every state is different and has different procedures. Commercial trucking companies have to deal with this all the time (it’s ‘unfair’ that they fuel up at their start and endpoint, and pay no fuel tax for the states in-between).Anyway, turns out by the time you do this, propane isn’t much cheaper to run than gasoline. The real kicker is going to come in a few years when they require road tax on electricity for EVs and plug-in hybrids. Right now it would be political suicide, but as states get more cash-strapped, it’s coming.",

[Chris Marion] knew he wanted to play with fire, or more accurately with fireball spewing valves, but he need a good project in which he could use them. Inspiration finally struck and he built this controller that
matches fireballs to the fret buttons on a Guitar Hero controller
. There’s quite a lot that goes into this but we think that he hit a home run. The basic components are a manifold with electronically actuated valves, another manifold for the pilot lights, and a modified Guitar Hero controller.
To interface the controller he used an Arduino along with [Bill Porter’s]
PS2 library
to read signals from the buttons. But the real labor intensive part of the build came with the manifold. There’s a hardware store’s worth of fittings and flexible copper pipe that go into that assembly. In the end this all came together in just one week.
[Thanks Bill]

Solar Monsters… You Know… For Kids!

"soldering"
] |
Teaching kids to solder using kits is a fun time, but most of these beginner kits are a bit mundane. Not this one, it’s
a solar-powered monster project
. The components and their wiring connections are printed on a sheet of paper along with a background for that particular monster. The base of the paper is glued to a block of wood and at each solder junction there’s a copper nail. This way the kids can line up the components, check the picture to make sure the polarization is correct for each, then solder onto the large and stable nail head. As you can see in the video after the break, when the solar cell collects enough electricity the transistor triggers a motor to spin the monster.
But don’t get the idea that kits are
only
for kids. If you haven’t tried your hand with SMD soldering yet,
this kit is for you
.

Broken Laptop Recovered Using An Arduino

"crossover",
"ftdi",
"serial"
] |
We see Arduino boards used in a lot of projects but we’ve never thought of using one as a USB crossover cable. That’s basically what [Jack the Vendicator] did to get his broken laptop running. When his video card stopped working he found himself unable to access the laptop. Newer machines don’t have a serial connector, which could have been used for a serial terminal, so he was at a bit of a loss since neither SSH nor VNC were installed. But he thought he might be able to
use the Arduino as a serial terminal connector
over USB. He plugged the Arduino into the laptop, and connected a USB serial converter from his desktop computer to the Arduino’s serial pins. In effect he’s just taking advantage of the FTDI chip, translating those signals back into USB on either end. Once he booted the headless laptop it took just a couple of blindly typed commands to get SSH running in order to regain control.

Sure, he could have blindly typed in the rest of the commands, but I’m assuming he didn’t because he also wanted to be able to use this laptop through VNC. So, if you’re gonna just piss and moan about a guy coming up with a creative way to do something, then just don’t come to HaD.In my book a hack is taking something and changing/using it to do something it wasn’t intended to do.

The point is not if it’s an interesting kluge to use the FTDI chip in the Arduino in this fashion, but if it was a necessary kluge. In this context, I can’t see why it would be necessary.

Plug the back in and nothing is corrupt. A HD failed and no data lost, rebuilt pretty quick. WHS is regarded as pretty good, even Apple users love it over time capsule or whatever they call it.Maybe hardware related? Is it one of the junky HP or Asus boxes? I don’t like the hardware the turn-key solutions come with, I installed it on my own hardware, an Atom board that used to be my Ubuntu server.Also, you can recover the data drives from an OS drive failure without rebuilding the volume, It’s a option during re-install.",

If you needed to code something, then will you publish the code?So yeah, it’s a great idea considering what was availible to him, a definate paradigm shift from what everyone else would have done.That said:@Bald_EagleThe old-school of hackers has the generation of “you want to know then figure it out” in addition to “I can show you the basics, but you should learn on your own as well.” Each hacker/cracker/programmer/phreaker/etc has a unique style of doing whatever s/he does, hence WHY they say figure it out–the way I learn is not the way you learn.

Getting Started With The Parallax Propeller

"parallax",
"propeller"
] |
The folks at [gadget gangster] have been working on an excellent set of tutorials for
getting started with the Propeller
chip itself, the open-source Propeller Platform Modules and the Spin programming language that’s used to control things. All of the basics and a growing selection of more advanced topics are covered in gorgeous detail, with most of the tutorials containing helpful photographs and screen shots, source code listings and video walk-throughs to help you understand what the authors are talking about.
Parallax is not new to the microcontroller game. Almost two decades ago, their BASIC Stamp embedded microcontroller was the springboard for many tinkerers. The Parallax Propeller is an easy-to-use microcontroller that’s been gaining popularity for a while now. Several Propeller support modules have hit the market recently, providing power supply and interface functions to the Propeller similar to how the popular Arduino platform interfaces with AVR microcontrollers.

"content": "I’ve almost completely converted to the Propeller (just a few Arduino/AVR projects to finish up first…) Here are a few things that are uniquely cool about the Propeller and the company that makes them:– The propeller itself has eight cores that run independently, and each core has access to all of the I/O pins. There is no need for interrupts. It runs at 80MHz, for up to 160MIPS. It can synthesize NTSC and speech without any extra silicon.– The Propeller Object Exchange (OBEX) is a wealth of code all in one easy-to-use place.– The designers of the chip visit and comment on the forums (when they have time) – how cool is that??– The price is comparable to Arduino with far more power.– available in both DIP and surface mount packages.And lastly, I must plug the fantastic 12blocks (12blocks.com) IDE for the propeller. If you’re new to programming this will get you up and running faster than anything available for Arduino. And even if you’re an experienced programmer, being able to swap around blocks like Lego bricks makes prototyping and development very efficient.By all means, check out the Propeller and make it a part of your next project!",

"content": "I use the Propeller quite a bit and am reasonably proficient in both SPIN and PASM. Some people hate SPIN, some love it. I like it. Like anything powerful yet efficient it takes a little self-discipline to learn – but the time is worth it.The concept of multi-core computing is interesting and powerful once mastered. Nobody worth their salt in the micro-controller field should claim proficiency without adding the Propeller (or something like it with multi-cores) to their resume.The Parallax Propeller Forum deserves mention – a great community providing excellent support. There’s also the Object Exchange on the Parallax site, a repository of interesting code for the Propeller. Then there’s the Unofficial Propeller Wiki – worth a look. Links are provided below…But the Propeller chip has some issues:* SPIN is kind of slow, especially compared with PASM.* COG RAM is soo small in my opinion.* Two or four clocks per instruction in most cases.* Too expensive unless you’re really going to use all the cogs.* There’s no double-precision, not even with Catalina or the Imagecraft C compilers; none (unless you write it yourself of-course).* It would be nice if there was more main RAM to support higher resolution video, if nothing else. (Gadget Gangster has a SDRAM board for added external RAM.)* The Propeller Tool IDE is native to Windows only and is closed-proprietary (but it is free).* The PLL hardware is a bit fragile in my opinion.The Gadget Gangster board is nice. It gives you an extra 32kB of EEPROM for user-storage. I suggest you get a real serial (two wire) 2X20 or (better yet) 4X20 LCD display to go along with your Propeller board; it is portable and indispensable for debug. Parallax sells some and Sparkfun has some too I think.There a new version of the Propeller due, maybe next year (I’ve given up tracking it). The new version will be a seriously enhanced version of the current chip. So you aren’t wasting your time working with the current Propeller. If I’m not mistaken both chips will remain in production.* Unofficial Propeller Wiki:http://propeller.wikispaces.com/* Parallax Propeller Forum:http://forums.parallax.com/forumdisplay.php?65-Propeller-Chip* Propeller Object Exchange (ObEx):http://obex.parallax.com/",

"content": "I was about to take the plunge into the world of Propeller the other day, but thankfully I took some time to research it first.The Propeller chip has zero peripherals. Specifically, it has no built-in ADCs, comparators, PWM, watch dog timer… and as others have mentioned, no interrupts. It has no internal flash memory or EEPROM for storing programs, so at the very least a Propeller chip requires (REQUIRES!) an external EEPROM or host to download from, or it cannot run anything.I like the idea of truly parallel multi-tasking, but since so many of the standard list of microcontroller functions would have to be performed in software or by external chips, much (if not all) of the advantage of parallel execution is given away. Even the speed advantage disappears when you compare single-cycle execution on an AVR at 16-20MHz to multi-cycle execution plus shared memory wait times plus inter-chip communication times on an 80 MHz Propeller.So to equal the functionality of a $4.50 USD ATmega328p, an $8 USD Propeller chip would need another $5 – 10 in chips (EEPROM + 6 or 8 channels of ADC), a huge pile of 3rd-party libraries, and a mess of integration time *before you even start programming your application*.Maybe I’m missing something, and to be fair I have never used a Propeller so I’m judging by the datasheets… but I don’t see how the Prop offers any value over a mid-level AVR or PIC.",

If you are paying 5 to 10 bucks for 32K EEPROMs you are not shopping in the right places.Libraries and timeLook at Parallax’s Object Exchange; page after page after page of downloadable, freely useable object libraries for any number of functions and uses – quite a bit of it professionally written and provided by the chip’s designers. As for integration time, that’s called a learning process and should NEVER be subject to criticism.Someone completely unfamiliar with any particular processor platform will look at similar concerns, but to actually take the plunge, now that’s a different story. Let me ask you in return: How long would it take you to “integrate” a PS/2 keyboard, PS/2 mouse, and 1024×768 VGA monitor into your next arduino project? How many pins would you have to use? How slow/fast would it be? How much would it cost? Answers for the Prop are 1 hour, 10 pins, real-time response, and less than 30 dollars. Hard to beat with any AVR platform that I’ve used (half dozen or so), not doable at all in the PIC world, and I’ve still got 20 pins or so left over for sensors, joysticks, network hosts, etc, as well as a few dedicated processors to apply to those external device tasks. Oh yeah, for 1 more pin I can watch things on my large screen TV and broadcast it to the bedroom television. I’ll gladly pay 7 bucks for such a chip (and I did), and spend however much time is required to learn to do these things.Like I said, this is not intended to be a flame, just a gentle reminder that those who haven’t tried the experience shouldn’t be the one’s knocking it.8051, 6811, AVR/Mega/Tiny/Arduino/BS1/BS2/AM188ES/386EX/Propeller, I’ved used ’em all and they are ALL excellent platforms depending on the task at hand. But only one, the Prop, provides for simulatneous multi-processing, and this is such a great new territory in uCs that my opinion is that all of you should give it a shot, if nothing else it’ll make you appreciate software multi-tasking on a whole new level.Steve",

"content": "As an brief aside to my above comment, I note that a couple of people on this and other sites have mentioned the lack of interrupts on the propeller, so I’d like to point out that the comparably priced AVRs offer 1 or 2 interrupts at most. With the Prop, you get 8 dedicated 32-bit processors with 512 double word bytes of RAM to deal with “hardware interrupts,” and each has at least three ways of recognizing the request, and the individual processor can actually sleep in between processing hardware requests. Probably the biggest benefit would appear to be that the hardware handling code is run on the dedicated processor in it’s own memory space while the rest of the Prop (including other hardware handling dedicated processors, as needed, up to 7 more) goes on about its business without the “interrupt” slowing down any other processes until its time to share some information, at which point the notifies the hub, posts its results in shared memory, and goes back to sleep. This is one of the greatest systems I’ve ever seen, and I’d trade a whole handful of 2313s for one Prop that can do this.As to timers, the Prop of course has a system timer and each COG has its own built in timing mechanism, setting one COG up to monitor and process a “watchdog” type condition wouldn’t be hard to do at all, but I’ll let a more experienced hack-a-dude fill you in on that, as well as setting up PWM and ADC/DAC i/o – I know it can be done because many a bot is out there running on the Prop platform, just don’t do so much with bots myself; I tend to use uC’s to monitor switches and events more than anything, and I plan on sticking with the Prop for a while.Steve",

Foldaway Photo Booth

For his wedding [Dave] wanted to have a photo booth but the $1k rental price was really getting him down. Instead,
he decided to build his own
. This cost less money and he gets to keep the booth once the festivities have concluded. He started by designing the assembly in Sketchup, taking into consideration the portability requirements that allow this to fit through doorways. What he came up with is a unit made from one sheet of plywood that folds up via piano hinges and takes about eight minutes to set up (video after the break). But where the design really shines is the all-in-one electronics module seen modeled on the right. It houses the monitor and the computer in one compact and rugged package.
If you like this you should also check out
the suitcase photo booth
and one other

Dome Light LED Retrofit

"dollar store",
"dome light",
"voltage drop"
] |
One of the bulbs in the dome light of [Pete’s] car burnt out. These were a bit hard to get at for replacement so
he thought he’d try something that would last longer
, and have no problem standing up to the vibrations that go along with automotive electronics. But plug-in LED replacements cost more money than he was willing to spend. Luckily there was a dollar store next door to the auto part shop, so he bought three LED touch lights for the dome and cargo bulbs.
After cracking them open he found that the LEDs were wired in parallel. He needed to put these in series in order to take advantage of the voltage drop. After de-soldering the bulbs he measured the characteristics of one, then calculated the voltage drop and resistor value using a worst case scenario of 14V to avoid damage to the light when the engine is revving high. From there he cut the traces on the board and rewired them. The reworked module fits nicely and as you can see in the image, gives a more pleasing light color than the orange of the stock bulb.

"content": "@AndyNominally no, the “orange” most commonly used in North America is the high-pressure sodium lamp. Low-pressure sodium is used in a few places but generally since it only emits that one color–not pure orange but a orangish-yellow, it produces no color rendition under it (unless you have a fluorescent color). It certainly is the most efficient light source out there but at great cost to color rendition, which is why increasing the pressure to broaden the sodium lines out to red-yellow in the HPS lamp is the way to go for the best combo of color rendition/efficiency.For @Sariel, the color choice on streetlamps is completely municipally decided and often may be from decades-old issues unrelated to human vision. If it’s new development, it’s usually orange HPS, or perhaps blue-white metal-halide. If it’s older, it could still be mercury-vapor. It is true that bluer lights are scattered more in the eye and cause more problems for human vision than warmer lights.It’s one reason why we need to point out replacing efficient HPS — “orange” lights — with blueish white LEDs is a bad idea. It’s less efficient, will cost more, and will create more light pollution and human vision difficulties (if compared with identical streetlamp systems).If white LEDs are demanded, at least use a warmer white LED with a color temperature matching incandescent 3300K. They are much nicer looking for most applications (excepting when you want daylight inside).",

Here’s a fun
video tour of a light testing facility
. Admittedly, its not as fun as watching
cell phones get abused
, but it is interesting. The video is only about 6 minutes long, and is mostly a narrated slide show, but is full of information. There’s plenty to learn about the bulbs themselves, as well as the testing procedures. What you can see above is a box full of LED testing units.

Calc Is High-tech For 1970’s Homebrew

Just one look at that banner image and you’ve got to be thinking “that’s old”!
This 1970’s era home made calculator
used a 4-function calculator IC that was quite advanced for its time. The only problem is that the chip couldn’t do anything other than calcuations, which left it up to the maker of this dinosaur to get the display and keypad working. Circuit boards were made by drawing on copper clad with resist marker. These controlled the VFD digits for the IC’s output and also fed it the user inputs.

Cell Phone Endurance Tests

Gone are the days when a phone would last you a lifetime and enter the days of glass covered mobile phones built to be sexy and sophisticated. With these new phones come new testing methods. Companies like Nokia are still dedicated to making the best phones possible and making them durable through vigorous testing.
The example shown in the article
, is simulating a phone dropping from a shirt pocket onto the floor. Nokia claims to use 200 endurance tests encompassing temperature, extreme usage (
use this button pusher
for you own test), physical drops, and exposure to humidity on each new model in their product line. Makes one wonder what other companies are using for their endurance tests. There’s video of the Nokia N8 Drop Test is after the break, and don’t forget to leave a comment if you know about other interesting test methods.

We get a lot of tips about Christmas light controllers but rarely do they contain the kind of juicy detail that [Vince Cappellano] included with his setup.
His video explaining the controller
he built is embedded after the break and it’s not to be missed.
We think there’s a lot of good design invovled in this porject. First off, he’s got eight physical channels, each with optisolation and a triac for 256 levels of power control. But he was able to double the control to sixteen virtual channels if you’re using LED lighting. That’s because on those strings half of the LEDs are reverse biased compared to the rest. By adding sensing circuitry to the incoming AC, he can switch the triacs to only send positive or negative voltage through the LED strands, which produces the additional virtual channels. And did we mention that he did all this using wire wrapping and point-to-point soldering?

It turns out that
hacking together a security keypad
is remarkably simple if you know what you’re doing. [Don] needed to add a keypad with an RFID reader on it. He had
previously built a USB RFID reader
and thought he could integrate those concepts into the new unit.
He once again started with a serial to USB converter and removed the voltage converter IC for later use since he doesn’t need TTL levels for this project. The keypad is a USB product and it turns out there’s a hub inside. With plenty of space inside for the serial converter PCB and a blank spot at the top where he mounted the RFID reader, he adding a few passive components to wire it up and connect it to the hub. The only connection is the original USB cord but the PC will detect both the keypad and the converter.

Shutter Remote For RICOH Cameras

[Toby] wanted to have a remote shutter trigger for his RICOH GR III camera. This brand doesn’t have a dedicated port for remote operation but a bit of
research allowed him to build his own trigger
. The camera’s USB port is used for triggering but not using the USB protocol. Instead, a pulse pattern on the 5V line identifies the half-press, full-press, and release states of the shutter button. From there it was just a matter of wiring up a circuit centering around an Arduino that leaves room for a lot of expansion into realms like
photo automation
.

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it’s his job to fix it. He suspected EMF interference so as a quick first step he decided to throw together
an EMF detector using an Arduino
. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the red antenna. In the video after the break [Adam] checks a room for possible sources of interference, treating the recharging circuit from the emergency lights as the most likely culprit. Since the ECG is many times more sensitive to EMF than the Arduino, this turns out to be a quick and easy way to make sure he’s not barking up the wrong tree.

It’s adaptable to 50hz power as well.The problem is the timing.. when you have a perfectly synchronized signal reading another signal and one goes out of sync (ie processing values for a bit of time), the two signals are no longer synchronized.61hz still oscillated visibly, 59 did not.And you’re right about the antenna… LOL! it would have to be something like 5000km long to be tuned perfectly for 60 hz..

Giving A Canoe Lawnmower Power

"lawnmower",

There’s the quiet serenity of paddling through the backwoods in a canoe, and then there’s this. It’s
a lawnmower motor powered canoe
that comes complete with steering wheel, throttle, and a stereo system. To keep the craft balanced the driver rides in the front seat while the motor is hanging off the stern of the boat. The biggest trick is not swamping the thing while getting the motor running, but future plans do include adding an electric starter. There is a kill switch for safety and it appears that top speed will not cause any stability issues. It’s hard to tell for sure from the video after the break, but it sure does seem to be loud!
[Thanks Rob]

Hackaday Sort Of Going To C.E.S.

"News"

[
"c.e.s.",
"ces",
"vegas"
] |
We have decided that C.E.S. just really isn’t as much of a hacker mecca as we would have wished. Sure there were brilliantly shining walls of new 3d televisions and cellphones and camcorders as far as the eye could see, but there was mainly just tons of marketing for very little innovation, and much less hacker-centric gear than we had hoped. We
had fun
and
tried to keep things interesting
, but just couldn’t justify sending people from all over the country to Vegas for a week this year.
[
Greg
] had planned on going anyway, so we’ll still get a few updates when he finds the bits that interest us. He should also be snapping pictures and tossing them on
twitter
throughout the show. Be sure to let him know what you would like to see.

Timelapse Photos For All!

[
"digital cameras hacks"

"timelapse"
] |
Find yourself wanting to do some timelapse but lacking the equipment? Why not build your own time lapse rig as seen in
instructables how to
by [Constructer]. To accomplish this, all you will need is a little wood, screws, a motor, and some batteries. The how-to says you can add extra voltage to speed up the rate of taking photos, or conversely reduce voltage to slow it down. We especially like the simplicity of this mechanical approach. No timers, no programming, only a motor. One downfall of this simplistic approach, however is that your “gap” between pictures will increase as your battery dies.

This is becoming such a popular hack we figure someone needs to come up with a name for it like Google-travelling or Google-cising (exercising with Google). It’s
a bike controller for Google Earth
. [Braingram] broke out his road bike, setting it up in the trainer in front of his laptop. If you already have a computer with a cadence sensor this will be a snap. These measure the crank rotation using a magnet and reed switch. So as not screw up his summer biking [Braingram] spliced into the sensor while leaving it attached to the bike computer. From there it is read by an Arduino which also monitors an analog joystick attached to the handlebars. A little bit of Python scripting and you’ll be ready to go.
Be sure to check out some of the other variants like
using an exercise bike
, or
adding a wearable display
.

Driving An 8-digit Split Flap Display

"12f683",
"pic",
"split flap"
] |
[Markus] got his hands on a split-flap display and
built a controller for it
. These sometimes can be found on really old alarm clocks, but [Markus] was a lucky-duck and managed to acquire this large 8-digit display which previously made its home in a railroad station. They work like a Rolodex, mounting flaps around a cylinder for a full alpha-numeric font set.
A PIC 12F683 was selected to control the display, using optoisolation to separate the 42V display motors from the driver circuit. From the video after the break we think he did a wonderful job of getting this working. It only takes six I/O pins to control and the sound and look of the digits scrolling leaves us quite jealous.
So what’s he got in store for it? The first thing he did was use it to count down to the New Year.

Controlling Real Objects Using Minecraft

[
"Misc Hacks"
] |
[
"arduino",
"led",
"minecraft",
"twitter"
] |
Most augmented reality takes images of the real world and superimposes virtual data on top of them. [Michael Winston Dales] went a different direction, using the virtual world of
Minecraft to control objects in the physical world
. In the video after the break you can see him use switches that he built inside the game to turn the LEDs pictured above on and off. You’ll also notice that in-game sign instructing a player to stand in one spot to Tweet. Since Minecraft is written in Java there are some mods that allow you to hook onto in-game events. [Michael] does just that, triggering his own scripts to send data to an Arduino, or use a Twitter API. Now this something that should be used with
the Minecraft ALU
. It takes the sandbox method of gaming to a new place, doesn’t it?

RC Pontoon From A Toy Car
|
Mike Szczys
|
[
"Toy Hacks"
] |
[
"boat",
"car",
"pontoon",
"rc",
"styrofoam"
] |
[Kevin Sandom]
built this boat
using a radio controlled toy car. The two pontoons are recycled from Styrofoam packaging material using some thick wire to connect them and provide a framework for the propulsion and control circuitry. The motor itself is a hobby outboard, which really only required [Kevin] to develop a method for steering. He walks us through the build process in the video after the break, where we find out that the original toy has a pretty bad design flaw. It seems the car used four AA batteries to drive the motor, but one of the four batteries was also used separately from the other three to power the control circuitry. Running that battery down faster than the others shortens the life of the whole.
This is considerably easier than the
underwater ROV hacks
we’ve seen before. We do think that it would make for a fun weekend project, and we’d bet you’ll get some weird looks for piloting what appears to be garbage around a pond.

[Brett Graham] and [David Cox] are taking the Kinect out into the world thanks to this handheld hack they call
the Drill of Depth
. Apparently, the Kinect wants 12V at 1A which is quite easy to provide with a rechargeable power tool like this Ryobi drill. The setup features a 4.3″ touchscreen display, connected to the Gumstix Overo Air that is running Linux. They claim that there’s a “legitimate scientific reason” for building the device but they’re not sharing it yet.
So what would you use this for? We wonder if it would be possible to roll a GPS into the mix, then use post processing from the captured data to recreate the environment in a virtual setting? Imagine if a weekend spent walking around campus and processing the results let you model your University and make it an add-on level for your favorite game. Or perhaps this could be paired with a regular camera to generate high-quality 3D skinning data for Google Earth. That’s what we came up with, what do you think?

It could become much like a digital walking cane for the blind… even if you couldn’t see, the device could offer a “force feedback” to indicate upcoming objects in your path by turning the drill motor with an offset weight attached to make it vibrate.Further this could be used as an electronic tape measure. Point the device and the software determines length, height and even depth of an object.I could think of SOOO many uses for a handheld computer that can see in “3d” with the capabilities of the Kinect.",

Seriously?1) Name five places you’ve been that were cooler/better designed than the best video game environments you’ve seen. Do you want a bunch of suburbs and supermarkets in your games?2) Speaking as a modeler with a bit of experience in game-targeted modeling, I’d bet my left hand that any meshes resultant from this device would have terribly inefficient vertex use (especially if you want to animate the mesh) and would almost be impossible to edit to something manageable and actually useful in a game.I’ve seen laser-scanned models, and while they are accurate and render nicely, there is no way they would be practical for the real-time rendering demanded by video games.I CAN see this tool being used to quickly generate low quality and inefficient models. Low quality and inefficient is probably a great trade-off for whatever the designers have planned for it.What I don’t like is people saying that a machine meant to interpret our mostly-unimpressive world could even come close to the beautiful models the pros create. It’s like saying that photographs are more beautiful than paintings.This post will probably come off as combative or even as flamebait, and for that I’m sorry.

Making Punch Card Programming A Snap

"punch card",
"trs-80"
] |
About thirty years ago [H. P. Friedrichs] pulled off a hack that greatly
improved the process of programming with punch cards
. At the time, his school had just two IBM 029 keypunch machines. One of them is shown in the upper right and it uses a keyboard to choose which parts of each card should be punched out. This was time-consuming, and one misplaced keystroke could ruin the card that you were working on. Since you had to sit at the machine and type in your source code these machines were almost always in use.
But wait, the school acquired a dozen of the TRS-80 computers seen in the lower left. They were meant to be used when teaching BASIC, but [HPF] hatched a plan to put them to task for punch card generation. He built his own interface hardware that connected to the expansion port of the new hardware. Using his custom interface a student could create a virtual card deck that could be rearranged and revised to correct mistakes in the source code. The hardware then allows the virtual deck to be dumped in to the punching machine. This broke the bottleneck caused by students sitting at the punch card terminal.
We think that [HPF] sent in this project after seeing the antiquated hardware from that
1970’s calculator
. These hacks of yore are a blast to revisit so don’t be afraid to
tip us off
if you know of a juicy one.

[John Creswell] built a heck of an
automatic bartender in a kitchen island
. The image on the left shows a top-down view of the inside of the cabinet. There’s a mini-fridge where the liquids are stored, and around the perimeter of the cabinet [John] mounted sixteen pumps to get the beverage up into your cup. Drinks are dispensed from the lighted serving fixture on the right by selecting your preferred cocktail from a computerized menu. According to his writeup the project was finished about five years ago, making us wonder if he’s tackled any upgrades such as adding support for smartphones.
[Thanks Zack]

One pump had to be discarded after fruit juice sat inside too long and molded. Subsequently, I flushed the tubes with water if anything nonalcoholic was being used in that line.The pumps themselves were too powerful out of the box, I had to use a AC-DC converter that reduced the volts. Or amps. I can’t remember without going back to check.I eventually removed the fridge, it wasn’t worth the hassle. I tried mounting it with the door facing out, but it didn’t quite fit. The tubes come out the door side because I didn’t want to risk nicking a freon line by cutting through the side; obviously that would have been the preferred method if I could have done it.As far as weight – I made the tiled top removable, so it wasn’t bad to transport. It was also on wheels, which are hidden underneath.Yeah… My bad about the air/liquid heat conduction thing.Feel free to contact me at creswel1 at msu dot edu if you want other information.",

The easiest method i can imagine would be to have a pipe run into the bottom of your bottle and a pressure line at the top which when pressurised should force fluid out the pipe into the rest of the system. It would make accurate measuring rather tricky though, because you would get different flow rates at different pressures and different volumes of liquid remaining. Small pumps for this kind of system are probably cheaper, easier and quieter. On the other hand for an industrial application it could be made to work quite well and I think your question may have just solved a problem of mine!",

Of course, the greater the vertical distance between the spout and the bottles, the greater the pressure of the column of fluid in the tube, which would begin to compress (or decompress if it’s lower…) the air and make accurate measurements harder, but if you design, say, a portable one that is more like a keg (with the spout in the side,) I think that could work pretty well.",

Quiet Dust Extractor From Scavenged Materials

As with many of the projects covered on hackaday, [bongodrummer]’s
Dust Sniper
came about because of a lack of effective commercial solutions, in this case to the problem of quiet dust extraction.
Workshops are generally full of dust and noise, both of which take their toll on the human body. This is why safety regulations exist for noisy and dusty workplaces and–as [bongodrummer] rightly points out–we have to take precautions in our own home and community workshops. Hearing protectors, dust masks and safety goggles are integral, but reducing the amount of dust and noise in the fist place is paramount.
Using mostly scavenged materials [bongodrummer] did a quality job building the Dust Sniper–and all for a bill of materials totaling £20. It has an integrated work surface, automatic switches on 2 vacuum lines to sync up with power tools, a cyclonic air filter that prevents clogging the HEPA filter and reducing suction power, inlet and outlet soundproofing, and a plain old power outlet for good measure.
Whether or not you’re interested in building an integrated workbench/extractor system like this one, we recommend you check out the details of the cyclone filter and the sound reducing components. Not only are they an interesting read, but they could be useful to apply in other projects, for example a
soldering station with fume hood
.
We think it would be really neat to include more cyclones in our projects. Stick around after the break to see [bongodrummer]’s prototype cyclone filter in action.

The air moves in a downward circular path then has to rise through the middle of the 2-gallon bucket to get to the “exhaust”, dropping the dust/dirt at the perigee thanks to gravity and centripetal forces.I haven’t bothered posting an instructable, etc. because it’s just too damn easy to build these.",

It’s a nice touch to engrave a heartfelt message on a wedding band, and my couples choose to do so. But you can say a lot more with a 20 second audio message. That’s exactly what [Luke Jerram] did by
etching an audio track into this ring
. He uses his custom-built hardware to playback the message, which you can see in the video after the break. The ring is an Edison Cylinder, which works just like a modern record player except that the media is on a spinning drum (the ring) instead of a rotating disk. We wonder if this would sound a bit better with
a high-end cylinder player
.
While you’re on [Luke’s] page you might as well take a look at his
image projecting ring
as well. It has a color image slide on one side and a projection lens on the other. Wacky!

Even the most thorough inspection may not raise the alarm that this Rovio has been
hacked to include LED headlights
. [Adam Outler’s] super clean work puts the two light sources on either side of the camera for maximum effect. It may not provide as many Lumens as
our external headlight hack
, but we were never all that excited about the black project box that housed it. [Adam] built the circuit on a scrap of perfboard, using a transistor to connect the LED pair to the battery, with the original LED power wire going to the base in order to switch the transistor.

CNC Cake Decorator

"cake",
"decorator",

"python"
] |
The
AutoFrost CNC cake decorator
is the result of a student project a Olin College of Engineering. [Tara Krishnan] and her classmates designed and built the hardware, as well as a Python interface that is used for drawing the design you want printed in frosting. The X and Y axes are controlled by stepper motors, with manual adjustments for the Z axis. The software has setting for the size of the cake, making it a bit more versatile than
the last mechanized decorator we looked at
. The GUI also allows for multiple colors which are applied one at a time, with the machine pausing for an operator to switch out the colored frosting container. All in all a nice build, but the next rendition should look to get rid of that second Arduino. We can’t think the code is complex enough to warrant two of them. Check out the demo video after the break.

(coming from a guy who would rather build a switch out of copper wire and a dc motor, to blink an LED than buy an arduino.) i like how they taught the one arduino how to use an arduino, so that they could use an arduino.. kinda like hooking a big, obedient dog to a little shithead dog so you don’t have to actually walk the dog yourself. swapping out the frosting colors really saves alot of trouble in the design. why deal with building a multicolor frosting printer when you can just type a couple lines of code?

[Johannes Agricola] recently held a workshop at the Peace Mission in Goettingen, Germany where
he shared his RGB LED flowers
. The small round PCB hosts an ATmega88 microcontroller which is running the V-USB stack so that the unit can be controlled by a computer. Each flower blossom is an RGB LED connected with four enameled wires which, when twisted together, make up the stem of the flower. [Johannes] took tons of pictures during the assembly while offering soldering advice along side the illustrations. The PCB is single-sided helping make this a great project for someone trying out surface mount component soldering for the first time. Or if you want something a little more free-formed try out this
lemon-juice powered LED flower

DIY driving controller
It looks like this steering wheel, shifter, and foot pedal were all made from string and garbage. That being said,
you can see it works quite well
. The setup just pushed keys on the keyboard, which reminds us of the junky plastic add-ons for the Wii remote. [Thanks Toumal]
Taping PCI express
[Pseudolobster’s] company was putting together point-of-sale machines for a retailer. They had surplus computers which really brought the price down but ran into a snag when adding the second monitor. The boxes wouldn’t play nicely with PCIe 16x. His solution was to scotch tape pins 19-82 on the cards, effectively turning them into PCIe 1x… and it worked! No link here but we wanted to share the trick anyway.
USB character display
[Simon Inns] shows how to
add a character display to a PC case
. We’ve seen him work with these PIC 18F2550 controllers
several times before
but we like how nicely this piggy-backs the display board seen in green.

using just a few components. The box is meant to be used to keep your stuff dry while camping, and the lens housing is made using plumbing fittings from the a home building center. There is a rail system that allows you to mount the camera securely inside, with a flexible button on the outside to actuate the shutter. If anything this is well designed and built, but we might still stick to using disposable cameras under water. Then again, the
pros build their own enclosures
so we’ll keep our fingers crossed for
that $2500 camera
as you try to capture that perfect shot.
[Thanks Troy]

But every 33 feet down you go, you add an atmosphere. One atmosphere is about 15 psi. So at 333 feet, you are at 150 PSI.I personally have some serious hesitations about trusting a $2000+ camera to this rig.Are there any provisions to handle removing the vacuum that will likely form inside the housing? Most pelican cases and such have a valve to handle that. But the valve reduces the “full immersion” waterproof nature of the box.",

Classic Game Emulation On The Dockstar

[Hunter Davis] is playing games like Contra, Monkey Island, and Quake 3 by
running them on a Seagate Dockstar
. We were shocked after seeing how well these run in the video after the break. [Hunter], who
used the ZipIt for game emulation
in the past, added a couple of hardware peripherals to get everything running. For sound he picked up an inexpensive USB sound card which was no problem to get up and running. Next he picked up a USB to DVI adapter and fired up
the Linux USB DisplayLink driver
. With the peripherals running he loaded up Fluxbox and the rest was history. Not bad for
a small network storage adapter
.

Reverse Geocaching Christmas Gift Box
|

"gps hacks"

"christmas",
"geocache"

This is the
reverse geocache box
that [William Dillon] built as a Christmas gift this year. He started with an interestingly shaped wooden box from the craft store. The clasp to keep it shut uses a servo motor on the lid with a wooden arm that grasps a screw on the base. As with the
original geocache box
, the
Frustratomatic
, and the
smaller geocache
, the box is designed to open only when in the correct geographic location thanks to the GPS module inside. That was a problem for [William] when a bug in his firmware locked the box during development while the key location was 1000 miles away. Luckily the box uses hinges that are attached from the outside with screws. We wonder how feasible it would be to use the mounting screws from the LCD screen to implement a coded emergency entry, using one as ground and the others as paths to microcontroller pins.

Get out the soldering iron and clear your schedule, it’s going to take you a while to assemble this
8x8x8 LED matrix which contains a total of 512 LEDs
. We’ve looked in on
a 3x3x3 cube
, and [Chr], who is responsible for this one, has assembled a 4x4x4 cube before, but this one is quite a leap in complexity. It isn’t just physical assembly problems that increase with scale, you’ll need to consider a power supply too since one layer of a 3x3x3 cube would need at 90 mA, but a single layer of the cube above requires 640 mA to light all of the diodes. Multiplexing is handled per-layer, controlled by ICs which share 8 data lines and are latched by a shift register. This means the display only requires 11 microcontroller pins for addressing. It is striking how well [Chr] explains the design process, and how cleanly he builds the driver circuits on protoboard. There’s a lot to look at and a lot to learn, not to mention the stunning results which can be seen in the video after the break.

The problem with Instructables and some other sites like that one is exactly that they force the user to sign up. Site owners should realize that they’re not alone: people cannot and should not be forced to mantain a password (or sometimes an entirely different login) for each site they would like to get content from.I follow dozens of sites/blogs/forums every day, and when one of them moves content from public to private it ends up in no time in my ignore list.The cost for asking the user to login also is not a valid reason as ads can be showed to guests too and there are easy ways to limit traffic for guests while mantaining content accessible: counters/captchas, etc.There’s no reason to keep asking for logins (when it’s not needed) so please stop it.",

When we first heard the parts list for this project, we weren’t too impressed. It has an iPhone connecting to an IObridge etc… But then we heard the next, and most important part, an
air cannon and an assortment of beer
. We were sold. As you can see in the video after the break, a fancy iPhone interface lets you select your beer, then dispense it into the cannon for delivery. The next step is to aim using a web cam mounted at the cannon and let ‘er rip! The beer is fired across the room and into your hands. We suspect that the amount of cranial injury, holes in the drywall, and shattered glass will greatly increase in frequency as the night goes on. Awesome.

Fabricating A Music-controlled Stoplight

[Andrew] built himself
a stoplight that flashes along with the music
. Unlike the
traffic signal we checked in on a year ago
, this one’s not a reused municipal fixture. [Andrew] imported a 3D model into Sketchup, printed out the results, and traced them onto
Bristol board
to make his templates. He cut out the parts, used a brake for the bending, then a combination of spot and MIG welding to complete the housing. Off to his school’s spray booth for priming, baking, and painting for a perfect finish.
The internals are what you’d expect. Each light source is made up of a cluster of LEDs controlled by an Arduino. Music synchronization is handled by a Processing script that [Andrew] wrote, which you can see in action after the break.

GSM Hacking With Prepaid Phones
|

Want to listen in on cellphone calls or intercept test messages? Well that’s a violation of someone else’s privacy so shame on you! But there are black-hats who want to do just that and it may not be quite as difficult as you think.
This article sums up a method
of using prepaid cellphones and some decryption technology to quickly gain access to all the communications on a cellular handset. Slides for the talk given at the Chaos Communications Congress by [Karsten Nohl] and [Sylvain Munaut] are
available now
, but here’s the gist. They reflashed some cheap phones with custom firmware to gain access to all of the data coming over the network. By sending carefully crafted ghost messages the target user doesn’t get notified that a text has been received, but the phone is indeed communicating with the network. That traffic is used to sniff out a general location and eventually to grab the session key. That key can be used to siphon off all network communications and then decrypt them quickly by using a 1 TB rainbow table. Not an easy process, but it’s a much simpler method than we would have suspected.
[Thanks Rob]

If telcos would care about their stuff they would’ve gotten paid off already and you would not be hearing about this whole crap.But what surprises me is why did they had to spend so much time on analyzing the protocol when you can buy open source phones like n900 which probably has a gsm daemon responsible for all incoming and outgoing calls and authentication and encryption which available with full source code and there is the OpenBTS project as well.",

Well it looks like the
Play Station 3 is finally and definitively cracked
. FailOverflow’s Chaos Communications Congress talk on console security revealed that, thanks to a flaw on Sony’s part, they were able to acquire the private keys for the PS3. These keys can be used to sign your own code, making it every bit as valid (to the machine anyway) as a disk licensed by the media giant. We’ve embedded the three-part video of the talk, which we watched in its entirety with delight. We especially enjoy their reasoning that
Sony brought this upon themselves by pulling OtherOS support
.
We remember seeing a talk years back about how the original Xbox security was hacked. We looked and looked but couldn’t dig up the link. If you know what we’re talking about, leave the goods with your comment.

The goal of this project is to make it possible to run Linux on a Microsoft Xbox console without a so-called modchip. A total of US$ 100,000 will be awarded by Michael Robertson (“donor”). Here are the rules, taken from Xbox-Linux.sourceforge.netProject B Prize Rulesby Michael Steil,Milosch Meriac,Andy Green, 24 January 2003OverviewAs the goal of the original Project B of the Xbox Linux Award has not been met, this part of the award will be extended until December 31st 2003. Furthermore, the rules will be extended, so that solutions that use very different methods can be awarded as well.The Microsoft Xbox is a PC-like gaming console that uses public key cryptography to prevent the user from running executables that have not been authorized by Microsoft. That is, the user buys PC hardware, but does not get the possibility to run applications Microsoft does not like, such as the GNU/Linux operating system. So, although the user has paid for his hardware, Microsoft controls which software can be used and the result is a Microsoft-only PC.Hardware modifications exist that give the user the possibility to run arbitrary code back, but these require opening the Xbox.The goal of Project B is to make it possible to run Linux on a Microsoft Xbox console without a so-called modchip. A total of US$ 100,000 will be awarded by Michael Robertson (“donor”).GoalsThe core goals are to be able to boot Linux on an unmodified machine, preferably by CD without opening the case, but via code directly copied to HDD or a USB device is acceptable too.The prize fund will be allocated by a committee chosen by the donor at the end of the period. People working in public, sharing good information on the ML, will naturally have a higher profile with the committee.Prize money will be allocated only for solutions that the donor can reward without getting his ass kicked into jail.If there are multiple groundbreaking solutions by the end of the contest, money will be allocated between them as fairly as possible.The committee may choose not to allocate all of the prize fund if all of the core goals are not met.All specific technical informations like PCB-Layouts, Binaries, ROM contents etc. that are needed to reproduce the solution have to be released using an appropriate Data Format and under GNU/GPL, GNU/LGPL or MPL license.Solutions must be practical in the sense that a 12 year old kid can hope to replicate them in terms of both complexity and costExample reward scenarioThe goals are deliberately not very specific about methods and rewards because the kinds of contribution we may get – and the mixture of them – are so unpredictable. For example, since some approaches may only make it possible to 1) boot Linux only from Optical media, and others 2) only from hard disk (and both will be needed), the committee may decide to split the award into two parts accordingly (in all these examples, it will be up to Committee to assess events and actually decide for themselves, these are just examples we can imagine, but circumstances and multiple entries could change everything: that’s why there is a committee to decide at the end).Partial SolutionsBoth goals can be reached either without additional hardware or with additional hardware (“partial solution”). If no additional hardware is needed, $50,000 may be awarded; if additional hardware is needed (e.g. for HDD and Optical media: an external device connected to USB or Ethernet, for Optical media: a CD/DVD that cannot be created by the end-user, but must be bought) only $15,000 might be awarded.Example: The design of a USB device that, when connected to an unmodified Xbox, makes it possible to boot Linux from a CD, might be awarded with $15,000, because it solves only a part of the Optical challenge. If it can boot Linux both from hard disk and CD, it could be awarded with $30,000, because it solves a part of both the HDD and CDROM problems.Example: A hard disk image that, when put onto the Xbox hard disk, will boot Linux from hard disk (but this image won’t work for CDs), might be awarded with $50,000 because it fully solves 1. A CD image that makes it possible to boot Linux from CD without any hardware modification may be awarded with $50,000, because it solves the Optical method entirely. An XBE file that boots Linux from either HD or CD/DVD, depending on where the file is stored, could be awarded with the full $100,000 because it solves both problems.In the event of a full solution (workable from HDD and Optical) becoming available before any other method, it is likely to get the full award and later partial solutions little or nothing; this is to encourage the most valuable HDD and Optical solution first. If there are partial solutions first, and then later a full (HDD and Optical) solution, we imagine the committee sharing any award a bit more evenly.RulesGeneral RulesSharing knowledge about previously unknown facts, code and hardware schematics get honored.If you find something out, don’t keep it to yourself to be the only one to be able to write code based on it. Share it with the others, your work will be honored anyway. Work on reverse-engineering devices of course gets honored, too.To be honored, work must be submitted to the “xbox-linux” project at Sourceforge, either to a developer or to the Mailing List. It is not enough to publish information/code somewhere else.We want people to work together, so there has to be a central point where all work concentrates.Every step has to be published, people have to work in teams.Development is much faster when people work together.Work that has already been done before this initiative has been started can be honored, too.But please submit it to the Xbox Linux Project.With “Xbox”, we refer to the majority of the Xbox consoles on the market when this initiative was started.If MS changes their box, that shouldn’t negatively impact someone’s successful work on an older box for sure. But all solutions should at least work on v1.0 and v1.1 boxes, or else not all money will be awarded.AwardsAll awards are determined by the awards committee. All decisions are final.The committee is chosen by the donor.The exact values of may change if the complexity a task was over- or underestimated. The 100.000$ for are always fixed, though.It’s hard to tell how difficult the different tasks will be. To be as fair as possible, the values may be adjusted a little.Completion of each step will be determined by the awards committee.Awards may be split between groups at Award committee’s discretion. Group contributions should designate the lead participant who the awards, if any, will be distributed to. For group contributions, it is the responsibility of the lead participant to disburse the funds.It will be impossible for the awards committee to decide the participation level of each person of a group, so we defer to the group coordinator.The outer limit on the initiative is December 31st, 2003.Please understand that we cannot wait forever.Legal issuesAll solutions have to be legal.If there is any doubt about it, the legality of the solution has to be proven, before you can get awarded any money.Legal issues are up to the individual participant, not the project.People that are working with (possibly) illegal methods may not participate.Don’t use the Xbox SDK. If your are a game programmer with NDA knowledge of Xbox details, don’t participate.Nobody has the right to get money.Don’t send us to court. This is supposed to be fun. We will do our best to be fair.Legal aspects can be discussed on the Mailing List.There are many additional opinions there.Getting StartedIf you want to participate in the project, you should read the documentation on the Project Website and join the Mailing List.SOOOO LOOOONG AGO NOW!!!",

You can expose everything on PS3 now except what loads lv0 on the CBE, and I think a few SPU binaries.One thing they poorly assume though is that SCE can’t patch the overflow without breaking old code.Not only can they fix PKI while keeping old keys, but they can fix everything outside what loads lv0 in ROM. LS memory overlaps as was demonstrated before geohot in the phrack paper, all it take is bounds checking on the SPE mailbox DMA..Also note that lv2 has no w^x, so you can leverage a full attack from lv2 LPAR if all you care about is Linux, and keep doing it..",

"content": "The thing that ruins these talks for me is the guy that says “This isn’t about piracy.. we want to run homebrew!”. Yes, that may be true.. but if you just want to run your own code you don’t buy a locked down/fairly expensive machine to do it. Why would you buy a PS3 for Linux? Why in hell would you buy an unsupported machine? Why would you pay through the nose for it? That explanation makes zero sense.I get no impression that the reason people spend time cracking security systems like these is to run Snes9x ports. If I had to guess I would say it was more of a pissing contest i.e. who can crack it first and interest in how the hardware works. I can totally understand that.. but why the hell do they need a guy with some slides that basically conclude “If they let us run our own code we wouldn’t crack the security for the profit-making part of the device”, which is total crap. You can run whatever code you like on Windows and that hasn’t stopped anyone from trying to crack all the different protections that come along.. 99.9% of Linux distributions are open source software, but you still see cracked versions of commercial software floating around.Making out that the reason the PS3 has been cracked now is that the OtherOS option was removed is just crap. Utter crap. How many people even cared when that was removed? How many people bitching about Sony being assholes for not allowing third party code actually intend to write/run any code?It’s been broken now because certain people have come up and delivered discoveries that have changed the whole outlook. Ironically (in contrast to it’s for homebrew! think of the children! guy’s opinion) the PSJailbreak (piracy device) appearing seems to have accelerated work considerably…",

You don’t get any sort of official development support or documentation. Doesn’t sound like a good cell development station to me. Sony’s official developer kits are probably a lot more than $8K.>Mercury Systems is offering the>Cell processor on a PCI Express card>for only $7,999.Do you have to have a cell processor for running Linux? Is it even well supported? Is it all that different from a PPC Mac running a PPC Linux distro? Does the architecture make much sense as a consumer grade computer? I guess for your ~$8K you get an unlocked platform, documentation, debugging support etc? If there was huge demand for Cell development kits there would be some cheaper kits out there like there are for ARM.. I guess the demand just doesn’t exist.>That’s otherwise known as a waste of money.Depends what you want to do doesn’t it? If you **really** need a Cell processor for something I would guess that ~$8k isn’t actually that much and that using consumer grade hardware with no support from the vendor for your intended use might end up more expensive especially if said vendor doesn’t guarantee hardware availability, continued support for however you’re loading you application (OtherOS here), you have to reverse engineer your own hardware documentation … oh, and how the hell do you interface the cell processor into anything external? With that $8K PCI-E board you get Rapid-IO etc support..I really doubt Sony would replace units under warranty that have been used as part of some HPC cluster. Sony subsidize the cost of the hardware and have no interest in providing cheap hardware to Cell developers.>> it dosent matter how many,From all the bitching about the removal of the OtherOS feature you would guess that thousands and thousands of people depended on it.. I really doubt that is the case.>>what matter is that the people>>that did care have the skills>>to make it run again.Which is really great. It’s nice to see people that want something to actually do it instead of just saying “why doesn’t someone do this ..”There is (or at least was) for example support in the mainline Linux source for a few machines that have a total of 1 in existence.. that’s some real dedication.Just guessing here again, but I reckon people would have been trying to break into all the various security systems if OtherOS was still present today. The argument that no one would have bothered hacking the system if full access to the hardware was allowed is also moot.. the security here is 99.5% based on the fact that the end user and their software has limited control, people buying that software is the main way that it makes profit (which isn’t optional) so there’s no way in hell you’re getting access to the hardware. This whole argument is pretty much identical to “I hate adverts on google, youtube etc moan moan moan.. but I won’t pay anything for those services either”.",

Lightsaber Boasts Detachable Blade And Crystal Chamber

[Bradley W. Lewis] continues to amaze us with
this Return of the Jedi Lightsaber build
. You’ll remember his fine work from his previous
Episode IV replica
. He’s taken the parts that turned out well for him and expanded upon them. In the demonstration after the break you’ll see the new version has a removable blade (which happens to house 90 LEDs). Just like the last time he’s got a Hasbro sound board and a speaker to add the Jedi-like sound effects. But there’s another trick up his sleeve. Two parts of the grip slide apart on a spring-loaded assembly to reveal the crystal that gives the weapon its sting. And as we found out the last time, [Bradley] really knows how to share his work in the build log.
Oh, and the drawings above? Well, someone who plans this meticulously obviously knows what they’re doing.

Adding A Serial Port Through An RJ45 Connector

[Mike Lu] likes to add serial ports to his routers to use for debugging but he didn’t want to drill holes in his new RT-N12. After a bit of head-scratching he thought about
repurposing the four unused wires on one of the RJ45 Ethernet connectors
. This would allow him to interface with the necessary signals and still have the option of using that port for a network connection. The first step was to build the circuit to output the correct serial levels and connect it to the unused pins on the jack. Next, to separate serial and Ethernet on the outside of the router he build a short adapter cable.
This is an elegant solution if you’re looking for zero case modifications. But if you don’t mind a few inconspicuous holes we love
the serial port used on this Dockstar

Lego Pinhole Camera

"lego",

"pinhole"
] |
[Bshikin] built
a pinhole camera out of Lego pieces
(
translated
). It is a fully automated unit thanks to the integration of the NXT pieces. It took a bit of careful calculation to get the film spacing adjusted to match the focal length, and quite a bit of tape was necessary to keep light out of the film chamber. But in the end, it’s an amazing build that takes decent pictures. The software has settings for film size and speed, and takes care of exposing and advancing the frame at the click of a button. See for yourself after the break.

IPod Nano 6g Closer To Being Cracked

Mike Szczys
|
[
"ipod hacks"
] |
[
"6g",
"ipod",
"irecovery",
"nano"
] |
[Steven Troughton-Smith] figured out
how to push signed firmware through to the iPod Nano 6g
. This is accomplished by modifying
iRecovery
to recognize the device on the USB after forcing a recovery mode reboot. So no, this doesn’t mean that it has been cracked since it checks the firmware you push and reboots if it’s not approved. But if you can figure out how to craft a custom image that passes the check you can call yourself a jailbreak author.

Since their invention in the 1500s, Hookahs have always been a way for craftsmen to show off skills by creating ornate, elaborate, and functional pieces of art. This still holds true
today
, as easily seen above. Found on the
Hookah subreddit
, this pipe was pieced together by recycling an old vodka bottle, as well decorating and re-purposing a number of plumbing items. Some finishing touches such as LEDs and gears to the base, as well as a set of turn-valves to the hose plugs give this hookah a very distinctive look.
As always, we at Hackaday do not recommend or promote smoking, no matter what goes into the bowl of the hookah. However, whether you smoke or not, the final product is worth appreciating. Be sure to check out the higher resolution pictures after the break.

But copper or brass (assuming it is truly lead free – not the 0.5% which is calledlead free”) and silicone (which can take 400 degrees F all day long without problems) don’t give off toxic chemicals.Now, cheap silicone caulk or peroxide cured silicone can give off nasty stuff when BURNED at 900F+ but platinum cured silicone can take 400 – 600F all day long without releasing anything.Pure pewter will melt.

You are right it gives off all kinds of nasty stuff. I don’t cut it on my laser cutter for this very reason. BPA in PVC though? I thought the decomposition products of hard unplasticized PVC did not include BPA – but epoxy or polycarbonate would. Same for DEHP and other phthalates – how often are those added to rigid PVC? PVC releases hydrochloric acid when burned as well. Nasty stuff.Glass works very well as a material to be heated. Prone to stress fracturing due to thermal gradients though but other than that it is fairly inert.",

What do you get when you combine two bikes, a couple levers, and a home made wooden shovel? Why, a light duty tricycle plow, of course! [Craig] of Firefly Workshop cobbled together
this contraption
to assist him in shoveling his 90′ driveway when a few inches fall. More convenient than a normal shovel, and much more environmentally friendly than his 8 Horsepower snow blower, this trike looks like it could actually make shoveling the snow fun. Not really much more here than meets the eye, we just wish we had a video to share of this sweet ride in action.

Wireshark, a tool recognized universally as being one of the best network analyzers available, has long been used by legitimate network professionals as well as a shadier crowd (and everywhere in between). While useful for analyzing both wired and Wi-Fi traffic, monitoring 802.15.4 protocols (such as Zigbee) have not been a common use in the past. [Akiba] of FreakLabs has brought us
a solution
which works around the normal limitations of Wireshark’s libpcap base, which does not accept simple serial input from most homebrew setups that use FTDI or Arduinos to connect to
Zigbee
devices
. Using named pipes and a few custom scripts, [Akiba] has been able to coax Wireshark into accepting input from one of FreakLabs Freakduino boards.
While there are certainly professional wireless analyzing tools out there that connect directly into Wireshark, we at Hackaday love showing off anyone who takes the difficult, cheap, out of the way method of doing things over the neat, expensive, commercial method any day.

New Years celebrations tend to get bigger and bigger every year for most people, and [Brian] takes no exception. In order to top his lighted tree of a few years ago, he has concocted a 40’x40′ set of
Seven-Segment displays
made out of Christmas lights, hung from nearby trees. These displays would start counting down the minutes an hour before the ball drop, and be synchronized with music. Also in the spirit of a New Years party, the music he has chosen is in the form of a
Power hour
. The control board [Brian] is using also comes with two extra outputs, which he plans to use for the most exciting possible additions: Fireworks and Flamethrowers.
Be sure to check back after New Years to see a video of the device in action. Be sure to Hack, Drink, and Party Responsibly out there.

Perfect Shots Every Time

A shot is a shot right? Well, not really. Usually we see a sloppy shot poured of a single type of alcohol and, depending on our current standing with the bartender, may or may not be full to the brim. The
Pousse-Cafe
makes an art out of your drinks by perfectly layering several liqueurs. Not only will it measure them out perfectly, but it is voice controlled as well. There are 3 liqueurs to choose from, as they were going for a specific, visually appealing drink (otherwise, why bother?). Judging from the pictures it looks like it’s using an arduino in conjunction with a laptop for control.
You can see a video of it in action after the break.

"content": "That video made me feel stupid for even watching it. Some points of interest:1. Use a sealed liquid resevoir (like the liquor bottle) and use your valve to allow in air rather than liquor out. This will control the flow equally as well, allow (probably) for faster pouring, and require little to no cleaning of the moving parts.2. Try a peristaltic pump. The last liquid-pumping project I needed a pump for I stole a peri-pump out of an old cheap-o fog machine. (probably not the best idea for potable liquids)3. Voice command is terrible. There is no commercial system I hate more than the corporate phone trees with endless “If you want to ____ say ____ now”. They get it wrong at least half the time, with no accent or connection issues. On top of that, your only voice command appears to be ‘Bartender, Drink’ which can also be handled with a giant blinking red button labeled ‘Drink’ with fewer errors.4. To switch a few GPIO pins on or off, or to handle USB I/O, you should use a smaller apparatus than an entire Arduino. Hell, a tiny PIC12F would be plenty for 3 pin control. You can handle all the timing right on the little 8-pin chip, too.5. Moar types of drink! Get 5-10 bottles and a library of drinks. You’ll need a slightly larger controller chip to handle valves, but you could shift register or multiplex them if you want to keep the controller simple. You’d only need 3 buttons to make it work(prev, next, pour), and some simple LCD display to show which drink is currently selected.",

There is a reason they are being used though – they are cheap and easy. That’s why an “over powered” arduino is used in tons of places where you could get away with something smaller.There is no problems at all with using an arduino in this case.

I believe you are uninformed.On a side note you make yourself look foolish by stating the reasons that using a PIC is superior to an arduino because YOU have skills and preferences that are biased towards them (preferences mean nothing in general). Also if we are going to talk about preferences, I would argue that most people would find the high level languages easier (the reason why scientists seem to always use java).Arduino development board = applePIC12F = orangeYou can’t compare apples to oranges! One is a bare IC the other a DEV board. However you can compare the PIC12F to an ATmega168 which costs $3.80 – very reasonable for a one off prototype.Also your are ignorantly ignoring the benefits of a ready made development board for prototyping. Sure if you look at component cost alone the PIC is cheaper, but if you include the time to build the support circuitry and write machine code its very easy for the cost of the PIC to eclipse the arduino (if you are producing one unit). It can also got he other way if you suck at C++ and are good at assembly.The bottom line is this – if you are making a one off prototype its useless to argue the cost differences. Use whatever prototyping tool you are comfortable with, and that gets the job done quickest because labor is pretty much the highest cost.",

While there are many ways to produce audible sound, Plasma Speakers have to be one of the coolest. Usually very complex and expensive, we received a tip for a beginners guide to making one of these
impressive novelties
. Handily included are a set of schematics (one very simple schematic, the other with a few artistic illustrations). There are also a set of warnings, which include sound advice to mind the heat generated by the MOSFETs, as well as making sure that your input signal isn’t too strong. The finished product is fun to listen to, so be sure to check out the example video after the break.

I sure did repair a lot of them though :).It was a fairly standard circuit they used, just a cockroft walton(sp?) multiplier, in parallel with a 1W 10MR resistor. There was also a second multiplier on some boards for filiments or something, I can’t remember. Oh and a couple resistors in a voltage divider to monitor the voltage out.The boards had slots routed in them between HV parts, and everything was immersed in oil.The company they were made for was CPI, but I don’t know the exact product/products it was used in.I’m going to hang onto them as I’m a class D nut.Honestly the real reason I haven’t went forward with it is ozone production.

Exactly how old (and large) a TV you’d need, I’ve never found out.3) Or just buy a new flyback without a rectifier. Check out “FLYEXP” at “www.amazing1.com/transformers.htm” for a nice assortment which includes some non-rectified ones. There may be other sources, it’s been more than a decade since I’ve looked.",

[Grenadier] had a piece of silicon carbide sitting around that he
planned to use when making a primitive diode
called a
Cat’sWhisker Diode
. While probing he noticed that one of the crystals threw off a bit of light. He popped it off and used JB Weld to attach it to a brass plate. The peculiar thing is that it generates light when power is run through it both forward and reverse biased. So what’s going on here? According to
an informed discussion on the phenomenon
there’s actually a pair of diodes in series but with their polarity reversed.

If many of the readers out there longed for a Segway for Christmas but Santa didn’t bring you one, you are in luck. The aptly named
Seg-Stick
by [scolton]
is a great way for cheap transportation. It uses a broomstick, along with two DeWalt cordless drills to power this bad boy on 6” wheels. Like
articles
done before on Hack a Day this is an awesome although rudimentary example of the things that can be made with a short amount of time, some determination, and a few power tools. Great job [scolton].

Build A Fusion Reactor In Your Home

At first we were pretty skeptical of this
home made fusion reactor instructable
. However, we’ve seen
home made fusion reactors
before, so it is technically possible, we guess. The construction alone is interesting enough to warrant a few moments of looking.
We’re not experts, so pardon us if we can’t tell you exactly what is going on, but we can appreciate the craftsmanship involved with the build. The vacuum chamber specifically is quite nice.
We know that some of our commenters probably have more experience here. Tell us, does this thing look legit?

He’s picking up neutrons, so there’s a good chance those deuterium ions are whacking together with enough energy to fuse. I’m wondering how he came about his inner grid geometry: it looks like he just went for something that only needed to be attached at the electrode base (i.e. no self-welding), but there may be some more thought behind it.",

I suspect if you make a serious attempt to purchase D2, someone from the government is likely to be knocking on your door (or worse).And finally, while they make references to radiation safety, they say nothing about what to expect, and give no clues regarding what they for shielding. At 40kV, X-ray radiation shielding is necessary, but not much of a problem. Their neutron detectors strike me as bogus.",

Ceramic is as opaque to gas as stainless steel. Check out products on high vacuum sites if you don’t believe it.*Why do I have to solder stuff for it to be legit? Electricity will still flow.*Deuterium is not easy to get, I spent nearly an entire summer tracking it down and came very close to requiring background checks but ended up coming out easier due to a lucky distributor find.*The neutron detectors are most certainly not bogus, these helium-3 tubes are the best neutron detectors in the world. Also bubble detectors are 100% accurate and are used for personal dosimetry in nuclear facilities. Lead is used for shielding x-rays which are only a risk through viewports at 40kv. When I operate in the 60kv regime, I shield the entire fusor and operate from a distance.@Joe Kazok – Large flanges are used for a perfect seal with no rubber. Rubber and vacuum grease are unacceptable in ultra high vacuum and hence the conflat style was invented. A single-use copper compression gasket is used between the flanges and they must be thick since quite a bit of torque is required on the bolts to get enough compression on the copper, and the flanges must not bend or warp or the copper seal could be compromised. You have to realize that a hole a few microns in diameter (hair can be 100 microns in diameter) is catastrophic and makes the seal worthless, this is a very well sealed chamber, not just a bell jar with grease at the seal.",

A better sign would be solid connectors of some sort (solder joints, crimped connectors, screw terminals – anything that suggests some thought was given to making the connection easy to make and break with reliability.)Tyler confirmed that D2 is not easy to get without background checks (that’s a good thing, and almost certainly requires federal agents to get involved), but that he got lucky finding some. I’m not worried about a couple liters of D2 gas. (How many micrograms of D2 is that?)I have only general ideas how to build neutron detectors – I’m more familiar with alpha, beta, gamma and X-ray detectors. The neutron detectors presented may indeed be perfectly valid – I have not researched them.",

Santa-Pede Challenge: Take Two

We are going to give the
Santa-Pede Challenge another try
. This time, you have till the end of January to do something (make it walk/crawl/scoot) with a dancing santa (or dancing musical holiday toy). As you can see
in my example
, it doesn’t have to be complicated or efficient in any way.
Here are some issues and questions we would like to address:
1. Many of you suggested a banner of some type to remind you.
Great idea, we were waiting for some other features to be added, but we’ve just gone ahead and popped them in. You can see the featured items at the top of the right hand column.
2. Some pointed out that the “Buy Break Build” title isn’t very hack-ish since we often preach up-cycling.
yeah, we really think you should find these santas anywhere. The alliteration is fun though isn’t it?
You can get all the rules by
going to the original post
. Just note that the last date for entries will be January 31.

LED Lighthouse Simulator

This Christmas [Bill Porter] decided to show his parents that those college dollars were well spent.
He upgraded the custom lighthouse light
which he originally designed in high school for their garden fountain. He even went so far as to craft some retail-worthy packaging for the gift.
We think it’s a wonderful design, on a custom PCB and based around an ATtiny85. A real lighthouse has a spinning lens to aim the beam of light. When the lens sweeps across your viewpoint there is a sudden flash and he’s recreated that effect using PWM. Take a look at the video after the break and you’ll see what we mean.
Also, during development he was plagued by a startup glitch
which we got majorly sidetracked reading about
.

Rock in the new year with
a guitar pedal you built yourself
. [Doug Kovach] took the time to share his project with us in the video after the break. He starts with a bit of history of the artists that have used fuzz pedals similar to this one. It seems great guitarists have been hacking since way back. [Doug’s] rendition uses the warm sounds of germanium transistors in a design that produces professional results. But if you need something a little bit less serious
try the stomp-box

"content": "Hi George, this photo is with the first circuitboard which was later replaced. One of the batteries was also removed and an external power source was hooked up to the power supply connector. Since the pedal uses a positive ground I left this till last to hook up so as to make sure the circuit worked correctly before getting into the weird power supply circuit.The write up is a bit confusing. This pedal is a combination of the Dallas Arbiter Fuzz Face and the Colorsound MKII Tonebender. There is no equivalent pedal on the market and there never has been. To the best of my knowlege I am the only one to create such a device. While Jimi Hendrix certainly had his pedal modified as did Jimmy Page neither of them went to this extent. Jimi Hendrix was a bit of a hacker but relied on Roger Mayer to do the dirty work and soldering for him, Jimmy Page was not. He simply heard sounds and asked others to make them for him.The photos are posted on Facebook and the video is on Youtube. I realize the implications of using Facebook to host my photos with but since there is nothing really proprietary going on here I am good with that. This is the public link to the photo set. You do not need to be a member of Facebook to view them. I have chosen to use Facebook to host them because with Facebook I can control who can see them and whether or not I want them public or private.",

I have done a small amount of research and photobucket and flickr and their ilk are always public all the time and have even more draconian statements about IP becoming theirs if I use their services. If I wanted to retain IP of my materials I would publish them on a website of my own. This is why I have not posted the schematic yet.I am undecided on whether or not I want to release it. What I did was not hard to figure out but I did hafta figure out a lot of other things in order to make it work properly and play well with other devices. What do you guys think?@zool your correct it used the NKT275 PNP transistors. The MKII Tonebender used the AC128 PNPs. I was originally using OC75 PNPs. The problem with all of these is gain drift as I stated in the video. Here in Arizona the summer temps get quite high and so render these transistors useless. This is why in the video I stated that I switched to the AC128k transistors. They have an aluminum heatsink and can withstand temps up to 500 degrees F with no gain drift. The rest of the specs are similar if not exact with another diffeerence and that being voltages of operation. the AC128K can withstand voltages up to 32 volts. So this has me thinking about doubling the supply voltages or even tripling them to 28 volts. This of course brings subsequent problems with sound. At higher voltages the sound will be cleaner thereby negating the fuzz distortion which is the reason behind all of this. Who knows though. This may be the start of a new type of overdrive pedal! Germanium overdrive a la Jimi or Jimmy anyone?",

"content": "Ok here is what I have decided to do. Since I do value the amount of discovery and engineering I have put together to create this pedal I will simply post links to each of the schematics and articles I referenced during its creation and engineering.Here goes:First of all the basic circuit is the Fuzz Face. There is a ton of information about this pedal online but this is what I used to create this pedal:http://www.geofex.com/article_folders/fuzzface/fftech.htmAnd:http://fuzzcentral.ssguitar.com/fuzzface.phpNow… The Colorsound MKII Professional Tonebender circuit: Be warned this is a beastly fuzz pedal. The circuit is not to complicated since it is only one gain stage more than a typical Fuzz Face added to the front of the Fuzz Face circuit. You may find information about the MKII Tonebender here:http://fuzzcentral.ssguitar.com/mkII.phpAnd here is the specific schematic I used:http://fuzzcentral.ssguitar.com/mkII/mkIIschematic.gifYou will note there are many variants of each schematic and pedal. I specifically chose the earliest versions of each pedal to work with simply because these are the ones using the Germanium Transistors. Later versions of both of these pedals switched to Silicon Transistors which changed the sound. Some people prefer the sound of Germanium over Silicon and vice versa. Some folks even like to mix and match and you will encounter many such circuits on the WWW.The problems with these types of pedals are their strange POSITIVE ground power supply (on earlier models) and transistor gain drift with temperature (also on earlier models). Later models switched to Silicon for stability and consistency not to mention being much cheaper. Transistor biasing can affect the sound and sonic tone of these pedals and you can certainly hear differences between a good or bad biasing of the transistors. The way I recommend to build the circuit is on breadboard so you can swap out biasing resistors to fine tune the circuit to your particular transistors and their specific gain structures. Take my word for it. It will be much easier to do on breadboard then after you have already soldered the board together. There are several locations to acquire Germanium Transistors. Steve Daniels over athttp://www.smallbearelec.comprovides both gain tested and pre-biased transistors and resistors sets. He also provides non-tested transistors for a few bucks less but you must measure and test each transistor to find its gain and biasing resistor amounts etc… Or not! The companies that built these pedals did no such thing. They simply built pedals using the next part grabbed out of a bucket of parts. So with that said the tone is completely up to you.. Its your pedal so build it so it sounds amazing to you and that is good enough!",

"content": "@Spork… First let me say that “Tone” is subjective and varies from person to person.To answer a few of your questions. As I have stated silicon transistors are much more stable then GE trannies due to heat instabilities. In order to substitute SI trannies for GE trannies the circuit must be re-biased to closer match the specs needed by the SI trannies. This means added resistors and caps to stabilize the circuit so the SI transistors can work correctly. Electrically this means different impedances and voltages. It means different gain structures and different ripple filters as compared to the original GE circuits. They just sound different. As for emulating the sound of the GE trannies this might be feasible through DSP but I would not count on getting it to sound the same. At least no more than emulating the sound of tubes versus solid state sounds realistic. To really understand this you would require an answer discussing atomic structure and physics.",

A resistive trimmer in series with the capacitor can help to damp the high frequencies to the amount of your choice.Don’t expect this trick to make silicons sound exactly as germaniums but for some people could be enough.",

Same specs and transistors and mostly the same circuit but 4 modes of operation as opposed to the 3 modes this pedal has. By the way the owner of this pedal still loves it and uses it everyday both on stage and in the studio. I also constructed his custom designed 100 watt tube amp as well as the channel switching device. He has had no problems at all in the past 4 years with any of them. The only things in his rig I did not make were the guitar and the cords and the pick. I have made two more of these pedals and they sold right away. I barely had time to finish them because they were so eager to use them. The creamy lusciousness of the germanium allows full chords as well as single notes unlike a lot of modern distortion devices. I will make an announcement on this thread when the new pedals are available for sale if anyone is interested. I have not had the time nor the place to do any electronics work in the past few years due to life and medical problems but now I am back to stable again so look for new devices again soon!

Obligatory tech tree
It’s hard to let a Christmas go by without looking in on a geeky Christmas tree project. Luckily, [Peter Davenport] decided to share his
Arduino and LCD shield tree
.
Blinking USB dude
If you’ve got a 555 timer and some commonly salvageable components give this
blinking LED man
a try. The version above is USB powered but that’s just to take advantage of the 5V regulated power.
Propeller business card
[Jay’s]
business card
is packing quite a punch with this Propeller microcontroller. We love seeing electronics design in cards (however unrealistic the price and portability may be), and this is a big processing upgrade compared to
the Tiny85 based offering
.
Flying high in NYC
We leave you with
a spectacular view of New York City
. This breathtaking footage is just as fascinating as
the first videos we saw from these folks

Upgrading An Old Polaroid Land Camera For 35mm Rolls

Ok, we recognize that this is a bit of an odd upgrade, since many would probably think that a digital upgrade would be more appropriate. However, we found this interesting anyway. [Marker1024] has taken this old Polaroid land camera and
modified it to accept a standard 35mm roll
. His list of materials may sound fairly MacGyver-ish with foil and sculpey, but his results look to be well done and fairly sturdy. We have to say that the aesthetics of the camera itself are quite appealing and we could see carrying one of these around. As interesting as the writeup is though, we can’t help but wonder what the pictures look like that came out of it!

The Land camera lens is designed to provide mediocre resolution and depth of field for a postcard-sized image receiver (the Polaroid print negative). A webcam sensor or anything similar is going to have a sensor the size of a pinhead, making the Land camera lens seem like a super-telephoto with extremely poor light gathering and resolution. Even 35mm film is probably being abused in that the lens isn’t delivering the image quality the film is capable of recording, because it was meant for a larger recording target of lower pixel resolution.",

Versaloon Can Program Hardware From Several Manufacturers

Versaloon
is an open source, USB connected project, that centers around an
STM32 processor
and provides a standard JTAG pinout. Above you see the Nano version which has a 10-pin JTAG connector, but there is also a 20-pin option on the Handy model. Great, another JTAG programmer. Well this can do a bit more than that. With a bit of help from the software it has been turned into a programmer for ten different types of hardware. Obviously this should be able to program anything that works with the JTAG protocol, but the script adapts it to work as an In System (or In Circuit) Programmer too. So far
the list of programming targets
includes STM32, LPC1000, LPC900, STM8, AR8, MSP430, and a few others.
We had some trouble finding an actual picture of this hardware. If you’ve got one, snap a picture and leave a link to it in the comments along with your thoughts on the device.

A Hacker’s Marginal Security Helps Return Stolen Computer

Gather round and hear the story of how a hacker outsmarts a criminal. [Zoz] was robbed and they got his desktop computer. Gone, right? Nope. Because of a peculiar combination of his computer’s configuration, and the stupidity of the criminal, he got it back. He shares the tale during
his Defcon 18 talk
(PDF), the video is embedded after the break.
[Zoz’s] first bit of luck came because he had set up the machine to use a dynamic DNS service, updated via a script. Since the criminal didn’t wipe the hard drive he was able to find the machine online. From there he discovered that he could SSH into it, and even use VNC to eavesdrop on the new owner. This, along with a keylogger he installed, got him all the information he needed; the guy’s name, birth date, login and password information for websites, and most importantly his street address. He passed along this juicy data to police and they managed to recover the system.

Homegrown as well as commercial off-the-shelf solutions have been available for years, such as the popular “Undercover” for MacOS and Computrace for Windows.He does make a good point that less security can be advantage. Full Desk Encryption, BIOS/EFI passwords, and login passwords can both help and hinder asset recovery. These measures will usually prevent unauthorized users from connecting to the Internet and activating the anti-theft platform. A frustrated thief may try to sell the property, or they may abandon it. In the best case they will return it.It is a common suggestion to leave an unpriveleged “Guest User” available on laptops so that thieves (and guests) can use it. Make sure there is a web browser and you can connect to Wi-Fi.Remember, if the thief must reinstall the OS to use the computer, the reinstall would result in the removal of OS resident anti-theft.Hardware embedded security such as Absolute, Intel AT and Phoenix FailSafe will survive an OS install, allowing the tracking component to reactivate after a knowledgeable user or a computer service shop has bypassed other security. However, this requires more work and skill, and may not be possible with some BIOS passwords. The person who ends up with a working laptop could be far from the original thief.And, at least on Dell and Toshiba computers, the security install state is visible right in the BIOS. It can be checked even without entering the setup password (if set), and explains that the feature is anti-theft. It’s useful for genuine owners to check their security but this could also tip off an unauthorized would-be user as well.",

Crash Course In HTML Manipulation From A Shell Script

Automating something involving data from the Internet can be confusing when it comes to pages generated by user input. For instance, let’s say you want to scrape data from a page that loads after using a search box. [Andrew Peng] posted
a quick and dirty example to help you write your own scripts
. The example he used checks stock on one of the websites he frequents. His process outlines finding the link that all searches are submitted to, establishing the method used to send the search string, and grabbing the resulting data. He parses it and sends off an email if it finds what he’s looking for. But this could be used for a lot of things, and it shouldn’t be a problem to make it alert you in any way you can imagine. Maybe we’ll use this to
add some functionality to our rat
.

Kodak ZX3 Teardown And Tetris

"Kodak ZX3",
"tetris"
] |
[Sprite_TM] was given a
Kodak ZX3 to play with
by a forum he moderates. The Kodak ZX3 is a waterproof HD camcorder in a cell phone / mp3 player form factor. After opening up the camcorder, he did some poking around with a scope and was able to locate a serial port on the board. It quickly became apparent that the system uses a proprietary kernel called PrKernelV4 rather than an open source alternative. Not letting the proprietary kernel get him down, he exploited the system by simply modifying a file called “autoexec.ash” on the sd card. He now has a Tetris clone easily launched from a previously unused menu icon. See it in action after the break.

Reading NAND Flash Chips Without Removing Them
|
Mike Szczys

[
"Microcontrollers"

[
"breakout",
"flash",
"nand",
"smartmedia"
] |
Here’s an interesting method of
reading data off of a NAND flash chip
. Often we see these chips desoldered in order to read and write data, but not this time. This method uses hacked adapters to match the pin pitch of the various chips. Above you see parts of a breakout board cut down to use as wedges. These are
drag soldered
to the pins of the chip, then the appropriate breakout pins were connected to a Smartmedia card reader, which can read NAND chips. There is also an example showing the flexible connector cable for a DVD rom used as the adapter to solder to a smaller chip. We still looks pretty tricky, but it might be less labor intensive than relocating the flash chip like we saw on that
Sega Game Gear hack
, as long as you only need to read or write the data once.
[Thanks Laurdy]

‘Tis The Season To Decorate Bags With EL Wire

We hope you’ve already got parts on hand for your holiday projects because shipping might be a little slow at this time of year. But if you’ve got a bag and some unused EL wire here’s a one-day project you should try. Make yourself a Tron-inspired
shoulder bag
, or
backpack
.
On the right, [PT] is doing fantastic job of modeling with his electroluminescent offering. This is another Adafruit offering that holds your hand each step of the way from designing, to sewing, to wiring it up. This will go great with
that glowing unitard he’s been working on
.
[Alan Yates] has also done a spectacular job with his Tron backpack seen on the left. He picked up his EL wire on clearance at a place called “big-W” after Christmas last year. They were selling 3 meter segments (each with their own inverter) for just $3. We’re happy he got a deal and even more pleased that he found a use for it.
[Thanks Drone]

Gaming On An IBM XT Using An NES Controller

[Frode] felt that using the keyboard for gaming on his old IBM XT computer was simply too noisy. He came up with a much quieter way to game by
building an XT adapter for an original NES controller
. If you haven’t explored the communication protocol used by the NES peripherals this is a great way to learn. Inside you’ll find a CMOS shift register that captures button states when it receives a latch signal. With that in mind [Frode] came up with a circuit to gather the bits from the controller, and generate input commands using the XT keyboard protocol without using a microcontroller. All of this is explained in the demo after the break.
Most of the NES controller hacks we see
permanently alter the hardware
. It’s nice to see one used without cracking it open.

Repairing A Broken RC Ceiling Fan

The ceiling fan in [Steve Vigneau’s] bedroom started giving him trouble. It is normally operated using a remote control but that functionality had become pretty spotty. He cleaned the contacts on the remote but still had troubles that could only be fixed by power-cycling the fan itself. When it finally died
he set out to repair the unit himself
. Above you can see the controller board from the fan. It was a bit too complicated for [Steve] to troubleshoot so he figured why not just stop using the remote control and make it work with a couple of switches? A bit of research led him to some basic fan schematics that he used for a reference. He need to remove a couple of capacitors and wire them up with one switch for the fan and another for the light. Sure, there’s no settings for speed or direction, but [Steve] thinks he doesn’t need to change them and always has the option to add them in the future.

"content": "Urza: Unfortunately it wasn’t the remote that was the problem. After cleaning the contacts a month or so ago it was sending pulses just fine. The problem was somewhere on the fan control PCB itself, and I opted to just step around the problem. I only use the fan at one speed and direction anyway, and I felt that the extra remote (and battery) was just a waste. I rather prefer the current setup with two simple mains switches; one toggling the light and the other toggling the fan.If in the future I want to change direction that’ll be trivial to implement with a DPDT switch (reversing theyellow and pink wires). I don’t like any speed other than low because then the fan is audible and bothersome when sleeping.",

Cobbling Together A CNC Mill

[Howard Matthews] never throws anything away, and because of it he was able to
build this CNC mill using parts that he already had on hand
. He pulled stepper motors out of broken stage light, precision rod and bearings from old dot matrix printers, and other various bits from his junk bin. We’ve seen [Howie’s] handi-work before, and this project is just as fun as
his Land Rover’s replacement speedometer
. Some highlights include manufacturing the nuts for the precision rod, and building a rail system for the bed of the machine. The latter looks a bit suspect, as any milling debris on the rails will cause you Z-axis problems, but now that he has bootstrapped a working mill perhaps he’ll machine an upgrade.
Update:
Fixed the link, added video after the break.

It will be lucky to machine anything other than wax beyond 0.005″, if even that, but it would work just fine for wax & plastic.If you want to machine metal, you can’t have flex in the body. You need rigidity, or you will have lots of deflection with heavier things like aluminum even. Getting rid of deflection is how you machine past 0.005″.If he even screwed together cross braces behind the boards, and sandwiched more boards, he might be able to get around 0.001″ in wax.This is inspiring, as really, unless you are working with very precise stuff, this kind of machine would allow all kinds of closely made stuff in wood, plastic, and wax for the homebrew people.

Since the forces applied to the machine are related to the feedrate you can cut slowly which results in much less force on your cantilevered tool, therefore less deflection and an increase in accuracy, at the penalty of parts taking forever to finish – which doesn’t bother many hobbyists. What bothers most hobbyists is when people find the need to compare the homebrew machine to their “Taig”.",

Teensy Can School You At Guitar Hero
|
Mike Szczys
|
[
"Playstation Hacks"
] |
[
"guitar hero",
"opencv",
"Teensy"
] |
[Johnny Chung Lee] put together
a system that is perfect at playing Guitar Hero
. He’s using the PlayStation 2 version and, as you can see above he’s combined a controller connector and a Teensy microcontroller board to communicate with the console using its native SPI protocol. This custom guitar controller receives its signals via USB from a computer that is monitoring the video from the console and calculating the controller signals necessary for perfect gameplay. [Johnny] wrote an OpenCV program that monitors the video, removes the perspective from the virtual fretboard, and analyzes color and speed of the notes coming down the screen.
As you can see after the break it works like a charm. It’s fun from a programming standpoint, but if you want a hack you can actually play maybe you should
build your own Banjo Hero

[Ian] wrote in to tell us about the
Guerilla Guide to CNC Machining and Resin Casting
. He came across it in the reference links to another project and says he wish he knew about it a long time ago. We took a look and there’s a mountain of useful information in the guide, which is written by [Michal Zalewski]. We won’t pretend that we’ve read the whole thing, there’s days worth of information here. But we will. The range of topics includes types of milling machines, milling materials, software options and use, safety, and the list goes on. Bookmark this (don’t forget
the second volume
), it might be just the thing to get you through the holiday with your family.

CNCzone is all fine and dandy but all forums have their cultures, norms, and quirks. Anyone have an idea where to find thorough information on say, the technical pros and cons between 80/20 vs MDF framing including technical data; not just some buffoon’s opinion. Ex. 80/20 seems fine and good sans the price however it has way less mass than MDF thus greater vibration induction will occur. Given that where is the sweet spot? What are the ideal options for framing? Does the author acknowledge multiple ideals based on different specification criteria?",

If you feel the same way and think you have the skills to use one, then get started! I bought mine (a Taig CNC ready mill) a few years ago and love it.Regarding the article: Unfortunately, the only aspect that impresses me is its length. It may be worth a read, but is so full of misinformation you shouldn’t trust anything in it. There is one point I agree with, though: Building your own CNC milling machine is likely to be a huge time sink that results in a mediocre machine (and in the end will probably cost more than commercial alternatives). Unless you really, truly know what you are doing, start with an off the shelf mill, preferably CNC or CNC-ready unless you already have access to a machine shop.Ketchup: The only sensible material for the structure of a real milling machine (tabletop or otherwise) is steel. You can make a decent CNC tool for cutting soft materials out of other stuff, just don’t ask me to call it a milling machine. CNCzone is a good site for information on a wide variety of CNC topics, including DIY.",

Another advantage it has over steel is less internal stress, and therefore better stability (less warping) when machined.————–Contrary to the text, common undercutting operations (e.g. T-slotting, dovetailing, cutting O-ring groves, etc…) are easily accomplished with form cutters. Boring heads, fly cutters, slitting saws, and other tooling enable undercutting.My full CNC 4th axis retails for around $375 (assuming a 4th channel is available in the controller), nowhere close to the $1000 amount cited.Backlash is not even mentioned in the section on accuracy.The typical table speeds claimed range from barely detectable to intolerably slow. My mill, which is nothing special, has rapids six times faster then the fastest speed mentioned.TiAlN coatings have no value for tabletop milling. These coatings come into their own when operations heat up on industrial equipment, table top energy is so low that my end mill is generally cool to the touch, even when cutting steel (using only compressed air cooling). It would have been better to mention that HSS tools are sharper than carbide and often work better for our purposes.The recommended spindle speeds (6-20 kRPM) rule out many useful operations. I’m much happier with my 1-10 kRPM spindle, though I wish I had an even slower speed available. I think high speed spindles are for specialized uses.The use of inexpensive tool holders, which clamp the tool with a set screw and are available for some spindles, is ignored in the discussion of tool holding.High helix angles are claimed to be “important for aluminum”, which is true if we are talking about a VMC or even Bridgeport, but has little relevance at the slow rates of material removal on desktop mills.I don’t mean to condemn the article.

For this application, high RPM is quite desirable.6) TiAlN: may not matter in many cases, but fundamentally, is beneficial when working in plastics at high RPM, because it reduces tool temperature slightly.@anon: the doc does mention MakerBot, Reprap, etc, and has a discussion of their limitations.",

"content": "Sorry if I sound critical about CNC milling info and machines, but if so it is because CNC milling is really hard to to – at least once we bring metals into the picture (and the article definitely speaks of metals). Even aluminum require a seriously amount of rigidity to cut at any significant rate of removal.My advice about buying off the shelf was based on the assumption that we are talking about cutting metal. Building a machine to cut wax or foam is a much easier proposition.MZ: Sorry for a few off-base criticisms. I scanned the article for specifics very quickly and missed on a couple of my points. In particular, I completely botched the conversion from mm/s to in/min.However I stand by my warning to reader. My biggest complaint is that the doc fails to set its boudaries: It mentions operations on all sorts of materials, including steel, and then gives recommendations appropriate for working only the softest stuff. Desktop mills can be used for a wide range of materials, and I find pushing the limits can be very rewarding (though also, at times, frustrating).I don’t what we are doing differently, but when I cut plastics, my end mill is usually cold to the touch at the end of the operation. Plastics are poor conductors of heat, so the heat generated by cutting is almost completely removed as the chips are ejected during cutting. TiAlN coated end mills are not useful here: they come into their own at ridiculously high temperatures (up to 800C – well above aluminum’s melting point). My supplier of choice for specialty miniature end mills, Harvey Tool, does not even offer TiAlN coating on their plastic cutting end mills, though they do offer amorphous diamond coatings which extend tool life in abrasive materials on some of their general purpose end mills.By the way, if I had problems with heat build up, I would definitely look at end mills optimized for the material being cut. Plastics are best approached with high rake and clearance angles. You might even consider router bits meant for wood.Form cutters are readily accessible. Every hardware store and building center I shop at carries Dremel bit #199, which I use to cut O-ring slots. The Harvey Tool miniature dovetail cutters I use are sold by my regular end mill supplier. Ball burs, and others fun cutters are found in various places. More importantly, you can shape your own cutters using blanks on fly cutters, boring heads, and gear cutting arbors.",

Bolting together steel to form a frame for linear rails/ballscrews is not rocket science, and when the average REAL CNC mill costs ~$10K(for a basic HAAS) then it’s stupid to condemn options in the <$2K range.I would say that the only legitimate reason to CNC a harbour freight is if you don't have room for something larger. After working in industry on Bridgeports I've never been able to be happy with the metal removal rates of anything smaller than a Bridgeport.If you're going to invest $1000 + on tooling and a CNC conversion, you might as well spend that much on a machine which will continue to pay you back on the investment in time savings.(spindle taper, motors, and ballscrews: none of that transfers)A bridgeport can bury a 3/8 endmill 5/8 deep in alluminum and handle a couple IPM. You'd be lucky to get .1\" on a harbour freight machine.That means it's 6X faster to make the same part on the bridgeport. When you get in to mold making that's 6 hour programs regularly. It's just not economic to do on a small machine. Who wants to watch a machine for 36 hours when for another $1000 you could have bought the right tool in the first place.",

Didn’t See The Lunar Eclipse, Make One!

Last night was a lunar eclipse meaning that most people would have been out gazing up at the sky watching it. For some the eclipse evaded them using cloud cover, but instead of giving up, they got innovative. [Garrett] decided to
build a moon simulator
to keep track of the eclipse using a few spare parts and some quick code. The parts that were required for this project includes an Arduino UNO, a singular ShiftBrite Shield, a ShiftBar, ChronoDot and a Satellite Module 001. This is the perfect project for the Arduino to be used in because he had to toss it together very quickly and it is meant to be a temporary solution. If he were to make this permanent, we would guess that he would make a smaller and more cost effective version of the electronics. He documents his experience on Macetech.com in more detail and the outcome is pretty amazing. Code is yet to be posted but hopefully it is forthcoming soon as well as a video of the simulator working.

Bi-color LED Matrix Clock Uses Point-to-point Construction

[Daniel] wanted his child to stay in bed until a semi-decent time each morning. The problem is the kid doesn’t know how to read a clock, so [Daniel]
built him a clock
. Yeah, doesn’t make much sense to us either, but we’ve used our own shaky premises for projects so who are we do judge?
He used a bi-color 8×8 LED matrix as the clock display. What caught our eye is the point-to-point soldering he used for the three strip boards that make up the device. Note the use of a drill-bit to break the traces when needed. Each board has its own purpose; the matrix drive, the logic board, and the power board. A PIC 18F4550 lets [Daniel] control the clock via USB, and takes care of lighting up the hour as a red number when it’s time to sleep, and a green one when it’s okay to arise. There’s a flashing pixel for seconds, and a binary readout of minutes along the bottom.
We’ve asked [Daniel] to post a schematic and an image of the clock face when displaying the time. No word yet but we’ll keep our eye on it. In the mean-time, check out this
clock that uses an RGB 8×8 LED matrix

No cutting wire on through-hole components, because once you make the final connection for a wire, you can just pull the wire taut and work it back and forth a couple of times; the excess snaps right off and you’re ready to make the next connection.Usually the board is laid out so there are horizontal/vertical “channels” between ICs and other major components, and wires are routed in those channels. Some people use mostly the 0.2″ space between rows on DIP ICs for the channels, leading to very small and neat layouts. I usually leave 0.2″ space between ICs as well for an additional channel. “Wiring combs” can be used which form physical channels that hold the wire in them, but they’re a bit pricey and I’ve never found them necessary. Instead, I just hold the wire down to the board and make a 90° bend, the wire will stay that way unless you tug on it too hard.Some people even do SMD this way, here’s an impressive example:http://elm-chan.org/docs/wire/wiring_e.html",

Once because I was in a hurry and being incredibly sloppy, and another because I had to rewire the board several times.@Doug/Whatnot: He didn’t just code the program in Forth. He also wrote the Forth compiler and runtime environment, and Forth is a natural choice for that because it’s so easy to write.Some years ago, I created something like the currently popular Bus Pirate. It was an ATTiny with a simple tokenized Forth engine, with commands added for digital I/O. A program on the host computer would accept short Forth programs, tokenize them, and send them to the MCU over the serial port for execution. The program could be as simple as reading/writing a pin. Or as complex as bit-banging a whole I2C operation; the MCU would execute it fully and then return the results without any further host intervention, and without having that protocol hard-coded in its Flash or using a dedicated I2C peripheral. Pretty impressive for 2k of Flash and 128 bytes of RAM, although the memory was limiting for anything more complex. I always liked the flexibility of this approach, maybe one day I’ll update it for a current MCU and release it.",

Add Explosive Power To Your Hi-five

It’s been a while since there was any advances made in the field if celebratory high-five-ing. [Eli Skipp] just finished her contribution, moving the art forward by
adding the sound of explosions to her high-fives
. Ignore the audio sync problems in the video after the break to see her Arduino and Wave Shield based offering. It uses a flex sensor to detect a high-five and has a bit of software filtering to avoid misfires when moving your hand or setting it down on a flat surface. It may look a bit ridiculous right now because of the bulk, but we could see a sleeker, cheaper version hitting toy and novelty stores everywhere.
Less useful than
a sign-language translating glove
, but easier to code and some would say more fun too.

When detected, multi purpose the Piezo as a sound generating device and play a loud rasp (or whatever).You could power the circuit from a small watch cell style battery and have the whole thing in a package the size you could wear as a ring on your finger.Just my opinion..",

Alarm And Wake Up Light

On the shortest day of the year wouldn’t it be nice to wake up to a bright room? This
alarm clock with an integrated wake-up light
is one way to do just that. It has some nice features, like a wood veneer that allows the seven-segment display to shine through, but hides it when the display is turned off. There’s also a feature to adjust the color based on ambient room temperature (another way to dwell on how cold it is in your bedroom).
A CC1101 RF chip came to the party, but we can’t figure out what it’s purpose is in this circuit. If you can shed some light on its involvement please do so in the comments.
[Thanks Eric]

This will be useful to my old parents who like to get up early in the morning. I want the led to light up their way to the bathrooms and the kitchen.I was thinking this could be done with some circuitry coupled to an arduino, but, I didn’t know what circuitry I needed. And my friend has been too busy to build this for me.Now you have done this and you deserve a prize. Can you add a few more features (listed above) to your project?",

Clamp Sensor Power Monitoring

[Bill Porter] has joined in the pursuit of an inexpensive yet effective way to monitor his power usage. He calls his project
the Not So Tiny Power Meter
, and shared both his successes and follies involved in seeing it through to implementation. There are problems; sizing issues with enclosures and his PCB, issues with noise when measuring low-current signals with the clamps, and even some wireless communications issues. But it looks like he’s got the system running despite these hurdles. Right now it streams data wirelessly so that he can display the current energy consumption, but he plans to add Google Power Meter functionality next.
We’ve seen commercial units using the same sensing principles that have been
hacked to show data online

So yes, it IS “real time”. I threw out a (wrong) guess. It’s actually one thousand blinks per kilowatt-hour.http://blog.janbottorff.com/?p=109Second: the biggest consumer of electricity will be electric heat (if you have it), followed by your dryer (if you use an electric dryer), followed by your fridge, followed by lights and computer equipment, if it runs 24/7. Most of those are resistive loads, and thus have a PF of 1. If you computer gear was made in the last 10 years, its power supplies are PF-corrected. So that really leaves just your fridge.If you’re having power problems, call your utility company. They have power monitors they can plug in / connect.",

It isn’t always obvious what the big users are, or how significant a particular action is.

(I am talking about the common 2 phase 60hz 120v common in North America.) Ideally, all power in the house will only travel on the 2 phases, with absolutely no current flow on the neutral.

This Hack Really Pushes Our Buttons

"button",

Yep, if you’ve got a button that needs pushing,
this is one way to do it
. [Travis] combined an old alarm clock with a car door-lock actuator and minimal logic circuitry to make this happen. When the alarm time is reached, the adjustable actuator comes down to press whichever button has been placed under it. In the video after the break he’s using it to schedule the start time for his Roomba, make his coffee, heat his pizza, or pointlessly press the clock’s own snooze button (classic). We think this is just begging to be used with a Rube-goldberg setup, perhaps to topple to
d
ominos that other robot took the time to set up
. Oh wait… that shows up in the video too. Fantastic!

Macro Photos Using An Under-light Rig

[Aki Korhonen] wanted to tighten up his macro photography setup. He already had the camera for the job, but wanted a fully adjustable target platform that he could easily light. What he came up with is
a jig to hold the camera and fine tune the subject
of each photo. It uses a frame with a piece of glass whose distance from the lens is adjusted by turning a knob. Below the glass a reflective surface redirects light from an LED flashlight up through the platform, lighting the snowflakes he’s shooting. A fixed LED source is in the plans for the next rendition.
Take a look at the overview of his setup in the quick clip after the break.

Well,
this metal suit
might not make you a dinosaur, but it would be perfectly possible for you to play one on your computer. Retailing on eBay for a mere $2,397.99 OBO (plus Freight for a 350 pound box), this device was made and used for the motion capture of Ugobe’s
Pleo Robot
. With the right external components (no word on what those are), it would be perfectly possible to get this suit up an going back on Motion Capture as all the onboard electronics are included. This setup would be perfect for anyone planning an animated dinosaur movie that needs some reference movements, or for any mad
scientist
engineer who needs a control rig for a 40 story robotic dino of death. The possibilities are endless!

German Engineering Produces An Overcomplicated Scarecrow

This
electronic scarecrow
keeps the birds away and makes your neighbors hate you at the same time. That’s because its way too loud, even if the next house is far away. The conrad.de folks that brought us
the climbing bike storage
device are at it again, putting together car audio and strings of lights as part of the bird-shoo-ing technology. In the video after the break you’ll see that they’re using a PIR motion sensor to switch power to an automotive amp and head unit. The speakers, strings of lights, and spinning doo-dads are all hidden under a black cape. When an unsuspecting bird tries to feast on the crops, the scarecrow unfolds its arm Dracula-style and raises a ruckus. We don’t expect to see this at a local farm, but maybe for next Halloween?

Keep Your Kids In Line With A Time Clock

When the cat’s away the mice will play, but a least
you’ll know when they came home if you use this time clock
. It’s called the Kid-e-log and [John Boxall] developed it to help a friend who wanted to keep track of their teenage children’s after school activities while they were still at work. He figured having them punch a time clock would at least let you know if they came straight home as they were supposed to. An RFID tag was issued to each (no, they didn’t
implant the tags
) and used to record the time. To keep fraud to a minimum the hardware has a battery back-up for its real-time clock, and the tag read events are stored to EEPROM for retention between power cycles. This doesn’t prevent common tricks like taking the reader with you, or sending your tag with a sibling, but it’s a start. See it in action after the break.

No, didn’t tell them, and as far as I know, they didn’t find out.

If I blew that trust, shame on me. If I blew it twice, shame on them. There was always an amount of grace, an “OK, I trust you’ve learnt your lesson”, if it happened again, they’d be there waiting.Personally, I learnt what was acceptable and unacceptable behaviour pretty quickly. I don’t think that has a lot to do with my own intelligence level or anything. I accept some people have specific difficulties which this kind of system would be well suited to, but (the point ‘ve been working around to) I can’t help but observe that these systems appear to become more and more popular all the time.In the UK, it seems to have always been phone calls. Then mobiles became common place, and it’s texts / mobile calls. Now it’s facebook messages. Whatever it takes to keep tabs on people. Even when they’re 20 or more years old.It saddens me. Why? Because for the people I know, they’ve grown to either be unable to make their own decisions, or to resent their parenting.I think this is good hack, it’s interesting, and it’s got uses.

Lifehacker’s Top Ten Of 2010
|
Mike Szczys
|
[
"Roundup"
] |
[
"2010",
"lifehacker"
] |
The end is near and Lifehacker is looking back on
their favorite how-to articles from 2010
. We found at least half of these interesting, including the hidden HTPC, lockpicking, and micro-TV-b-gone showcased in the image above. But you can also find tips on using your WRT54G router, stacking malted beverages, and making things glow through chemistry. If your heart goes out to our plague carrying house-mates there’s a no-kill mouse trap. They’ve even included a hack to add a USB port to your car… an article which
we covered back in 2009
. Enjoy!

At the end of October we announced the Buy, Break, Build series kick off with “
The Santa-pede Challenge
“. The goal was to get your hands on one of those annoying dancing santas, tear it apart, then use its parts to build something that walks. We got our hands on some cool prizes and even got [Phillip Torrone] to be a guest judge. Join us after the break to see just what we came up with and maybe have a few laughs.

So, as you can see in the video, this contest was a complete failure. We didn’t get a single entry. I quickly tossed this horribly lame attempt together in about 30 minutes. I’ll show some pictures of what I did, just for fun. It really doesn’t technically “walk” so much as it creepily scoots across your desk making you question your life decisions.
Here’s the beginning of the disassembly. Nothing amazing here. You can see that his lower half is a solid plastic piece (not jointed or motorized).
Here is the basic breakdown of what I did. I cut off the feet, Removed the servo that made his hat flip back and forth, and melted the middle piece to for the leg things. There is a wire that went into santa’s arms. This was too thin and flexible to be useful for much of anything so I just tossed it in the parts bin.
I couldn’t find the attachment for my propane torch, so I had to resort to some pretty questionable tactics. I wouldn’t recommend using a space heater to get your plastic soft for most projects. It did get the job done though. After putting this piece back on, all I had to do was tweak the newly created “legs” until it pulled itself forward. Its pretty pathetic, I know. It was meant to be the joke entry that made all the others look good.
What we would like from you, are ideas. What contest ideas do you have? What would you compete in? What item can you think of that has tons of hacking potential for a variety of skill levels?

"content": "I think it’s a cool idea for HaD to have contests like this. A lot of the contest was set up well. The theme item was cheap, so us broke hackers would not be excluded. The rules were open-ended enough to allow for a lot of creativity, and the categories allowed us to take our creativity in our own directions.I guess that wasn’t enough to get people to participate. For me, the theme created some cognitive dissonance. If I were to try to make a walking robot, I wouldn’t be excited about the project unless I had plans to do something awesome. If I wanted to do something awesome, I wouldn’t want to be time-limited or be forced to incorporate some arbitrary part. So I’m left with doing something that is uninteresting to win a contest. That’s when the prizes start to matter. The only one I wanted was the MintyBoost, but I figured I could make one myself for about the same cost as a mechanical Santa.I do like how HaD has been trying to engage its readers more, and I hope that continues.",

It’s all well and good saying that something is on offer everywhere and it’s really cheap but people are often not too inclined to go out and buy something for a contest like this and also, people have different stores/live in different countries and may have never seen the item before in their life.As was suggested, you need something very common. Supply a list of parts that everyone has and see what the best thing people can come up with is with the addition if minimal parts.Old mobile phones, CDs, computer parts, paper, card etc.If you supply a large-ish list then people may not be able to get/have everything but perhaps enough to make something cool from things in the list.Mowcius",

[Trucki] wanted to upgrade the internal storage on his JooJoo. There’s an mSATA connector inside but devices that use that protocol are hard to come by and when you do they’ll cost you and arm and a leg. He knew he could get solid state drives cheaply that use the mini PCI Express standard, which is mechanically compatible with mSATA. So he set out to
alter a mini PCI Express device to work with the mSATA protocol
. This entails swapping the transmission lines and rearranging the voltage traces on the connector. To handle the TX- and TX+ lines he desoldered their decoupling capacitors and realigned them to trade their signals. For the 3.3V lines he had to cut the feed and solder jumper wire to the correct pads.
This is some nice work which let him add a 32 GB drive for just sixty Euros. Since the device only comes with a 4 GB SSD an upgrade is almost mandatory if you’re planning to
install an alternate OS on the Joojoo
.

The Aspire Ones, unlike the Eee’s, used standard components for their models. Have a 8GB model AAO, and yes, those SSDs are worthlessly slow. I rerouted one USB port to be internal and booted Linux using a SD/USB Card Reader. Was loads faster than the internal SSD.Shame the left side SD slot isn’t bootable.
