Snega2usb Changes Name, Learns New Tricks

"virtual boy"
] |
[Matthias Hullin], the creator of the snega2usb let us know that its
name has been changed to the Retrode
. We
watched this device
go through the development cycle and learn to read SNES and Sega Genesis cartridges via a USB connection. Now it’s seeing some hacking to extend those capabilities. [Jon] managed to
rig the Retrode up to read Virtual Boy cartridges
. The
Virtual Boy
was a Nintendo console from the mid ’90s that used two different screens in a glasses format to produce a 3D gaming experience. Now that the cartridges can be easily dumped you have a chance to replay the titles using an emulator.

Of course, they’re called scanners, not screens, since there isn’t a large surface covered with pixels like a traditional display device.It’s a very interesting display technology and I would love to see a full color version using the OLED chemistry that was on HaD a while back. One row each of three colors would be a lot easier to make than a huge matrix of them. Too bad I can’t get the crazy chemicals…",

GPU Cooling To Fix RRoD

[Rbz]
fixed his friend’s Red Ring of Death stricken Xbox 360
by improving the GPU cooling. Because an overheating GPU is a
common cause of the failure
, he first tried to replace the thermal compound for better heat conductivity between the chip and the heat sink. This helped a bit but within two hours the problem was back. Troubled by the heat discoloration on the bottom of the DVD drive, he removed it and screwed a cooling fan to the GPU heat sink. That did the trick, so he moved the drive to the outside of the case with the aid of a longer SATA cable. It’s not pretty, but it worked.

Light Up Your Ride With An LED Mohawk

"helmet",
"lithium iron phosphate",
"mohawk"
] |
[Garrett Birkel’s] weekly ride usually features some pretty wild costumes. He wanted something to step up his own look so he make this
LED mohawk bike helmet
. He had an
LED strip
to start with and found a way to use acrylic and clear plastic tubing to fold the lights into the appropriate shape. From there he designed a PCB for some DC-DC converters to provide regulated power. The juice comes from Lithium Iron-Phosphate cells, the same kind we saw in
the electric bike assist battery
a few days ago. We find it a bit wild that you can pick out the PWM of the LEDs in the lens effect of that photograph.

The data in the CMOS inside the digital camera being used to take the movie is read progressively in horizontal strips, but the electrical signal is also transferred off the CMOS itself along a vertical array of wires, and too much charge above or below the region currently being read will cause interference as the desired line is shifted down for reading. It has nothing to do with the optics and everything to do with the sensor.",

Ditch The LPs And Build Your Own 3D Scanner
|

"Misc Hacks"

[
"3d",
"blender",
"laser level",
"python",
"scanner"
] |
Find yourself an old record player, a laser level, and a digital scanner and you can
build a 3D scanner
. That’s what [Rob] did. The camera and laser level are mounted on the turntable for steady rotation. The camera captures the vertical laser line traveling around the room by recording 30 fps at a resolution of 640×480. This data is then translated into a
Blender 3D
file via a Python script and the
Python Image Library
. You can scan a whole room or just a small object. The face above is the result of this image capture after a bit of processing. [Rob] found this worked best in the dark and when scanning surfaces that are not reflective.
Make sure you also check out
the camera-and-projector scanning method
.

Today’s the day the Google announces this year’s participant organizations in the
Google Summer of Code
. If you’re not tied down to a job this summer we hope you’ll take advantage of this opportunity to learn by doing and contribute code to a great open source project all at the same time.
A lot of our favorite software has benefited from GSoC in the past. XBMC
has participated
before, as well as WordPress,
Asterisk
,
MySQL
,
Bluez
,
Natural User Interface Group
, and
many more
.
Student applications are accepted between March 29th and April 9th. If you’re accepted in the program and excel at your work with passing grades at mid-term and final project dates, you’ll see your pockets grow by $5000. Get out there and put your mad coding skills to good use while you have the chance.

[Joel] has a very specific color temperature of lighting he wants in his home. So specific, he’s decided to
build his own LED lighting to get it
. Actually, he’s still searching for that perfect shade of white, but doing so has learned a lot. He initially made some very pretty PCBs, but then found that hand soldering them made quite a mess. What better time to delve into reflowing? He shares his positive initiation to the skillet method in his
latest update
. The search still continues for that nice warm glow he’s desiring. We’ve actually seen [Joel] before, he
likes smoked meat

"content": "I was gonna post this on the guy’s page, but its down, so ill post here as I wrote this already.A little on lighting theory…Single color (non-white) LEDs emit very narrow wavelengths of light. While it is true that mixing the primary bands of color, red blue and green, will produce ‘white’ light in theory, it will be lacking in a majority of wavelengths that would otherwise be found in true white light or sunlight. What this means practically, is that the quality of light will not make an object’s color ‘pop’ unless it falls in one of these narrow bands. So, mixing amber light from red and green LEDs will make amber objects look muddy, while an amber LED will make an amber object vibrant. Now you are using while LEDs, and that will fill the spectrum nicely, but your red green and blue LEDs will just cause ‘spikes’ at their respective wavelengths. Here is a graph of the RebelColor LEDs by wavelength (http://imgur.com/ckfhv.png). You can see the major gaps between colors even when there are all 7 colors, so using just three makes this more pronounced. If you really want to mix a nice color of white, you are better off mixing different color temperatures of white LEDs. As you can see in these two images (http://imgur.com/HVvby.pngandhttp://imgur.com/S1rYQ.png), White LEDs have a broader and softer curve, albeit irregular with the spike in the blue band. Perhaps mixing various color temperatures of white could give you a more palatable quality of light. If you line up the three graphs, the two white and the 7 colors, you will see the valleys in white that you may want to fill with other color LEDs. That being said, Incandescent light, no matter how energy inefficient, will always produce a warmer, more visually pleasurable quality of light.",

PCB Drill Press On A Budget

An accurate drill press is an essential tool for making your own through-hole printed circuit boards at home. Reader [Josh Ashby] offers up
a solid design using scrap bin materials
.
A major issue with PCB drilling is that even the slightest horizontal play will snap the delicate carbide drill bit. Hobbyist-grade tools such as Dremel’s drill press attachment are usually too sloppy for this task, while
a more precise instrument
might set you back a couple hundred bucks.
[Josh’s] design uses a nylon “sled” moving vertically in an aluminum u-channel track. Most of these materials were
salvaged
or were acquired inexpensively from a local hardware store, and assembled in less than a day. Surprisingly, this low-tech approach has proven sufficiently smooth that he’s yet to break a bit while drilling. And the entire setup,
including
the knockoff Harbor Freight rotary tool, cost less than the wobbly name-brand accessory alone.

"content": "@jeff-o: I’m not, quite, as quick to bash as FredP but he does bring up a legitimate point. Sure, you could build this using scrap wood or MDF but would either of those materials have the same dimensional consistency of Nylon sheet? The primary point of this project was the ultra-straight/smooth motion of the mechanism which was able to allow the drilling of PCBs without breaking the bits. In my experience, wood based products tend to be much less even and straight then other materials. They are also much more susceptible to swelling, contracting, and warping due to ambient humidity and temperature.It’s very likely that the properties of the Nylon sheet material are the primary thing that gave the device the precision that set it apart from equipment like the Dremel’s drill press attachment and, as FredP suggested, large scrap pieces of 1/2″ Nylon sheet isn’t the kind of thing most people are going to find lying around unless “Grandpa already has a well stocked workshop”.All that said, even at ~$117 (the $40 mentioned plus $77.19 from McMaster) it’s still cheaper than the “couple hundred bucks” mentioned in the summary for the cost of similarly capable equipment (assuming that value is correct, and the $40 Harbor Freight drill press isn’t capable of the needed precision). On top of that, McMaster might be an easy place to find the stuff, but it’s almost always much more expensive than other sources. A little shopping around should bring the price down a lot.",

Before we get into the how-to, we felt it would be appropriate to explain a little bit about how this came to be. As many of you may remember, a couple of months ago
we attended CES 2010
. While there, we also attended the
It Won’t Stay in Vegas Blogger party
and ended up
meeting the guys from Woot
. After all of us spent a little bit of time appreciating the open bar, a group of us stood ended up standing around and talking shop for a while. All of a sudden, a member of our group,
Jeremy Grosser
, proposed the idea that Hackaday and Woot form a partnership. Basically, they would give us a heads up on what they are going to sell and we would write up a how-to on how to do something cool or useful with that product. Then, when the day came for Woot to sell the product, we would post our how-to. What you are reading right now just so happens to be that idea in action,
the first official partnership between Hackaday and Woot
. In this how-to, we’ll be taking apart the Wowwee Rovio mobile webcam robot, adding some super-bright LEDs for better see-in-the-dark action, and see how some software called
RoboRealm
can give it a little bit of artificial intelligence.
If don’t have a Rovio yet, you should probably head over to
Woot
and pick one up so you can follow along. Also, be sure to pick up a copy of RoboRealm at
deals.woot
while you’re at it. It is important to note that while writing this how-to, we used a modified design of the
Rovio Head-Mounted LED hack
, posted to RoboCommunity by [Rudolph].
Parts
– 6 super-bright white LEDs (Ours were rated for 3.3v with an intensity of 7000mcd.)
– 1 2N2907 PNP Transistor (We found ours in a 15 transistor combo pack from RadioShack.)
– 1 22ohm resistor
– 1 2.2k ohm resistor
– 22g solid hookup wire
–
RadioShack 3x2x1″ Project Enclosure
(We used the plastic back panel as a place to mount our LEDs.)
– 5mm LED holders (Optional. We ended up using them to mount our LEDs in their poorly drilled holes.)
– Heat-shrink tubing (Optional, but recommended.)
– A small strip of perfboard
We picked up most of our parts from RadioShack, but these parts are so common that you should be able to pick them up from any electronics components store.
Disassembly
The first step towards giving our Rovio some much needed extra light is, of course, to disassemble it. After turning the Rovio upside down, remove the six phillips-head screws and carefully remove the top shell to gain access to the Rovio’s internals. While you won’t be able to fully detach the top shell, you should be able to lay it next to the bottom part of the Rovio as seen above.
Inside of the Rovio, there are two main PCBs, the control board and the power supply board. For the purposes of this how-to, we will only need to modify the power supply board. To gain access to the power supply board, simply remove the two phillips-head screws that secure the board vertically. After you gain access to the board, you will then need to identify the ground and positive pads on the PCB. We will be tapping into these pads later to power our array of LEDs. One other item of interest to us is the white wire leading from the control board to the LED headlight board. This wire will allow us to control our new headlights through the Rovio’s web interface.
After firing up your soldering iron, you’ll need to solder two wires onto the power supply board. As you can see above, there are two areas with tiny little holes, allowing for easy access to both GND and VCC. After you have soldered both of these wires, screw the board back in and then turn your attention towards the white wire mentioned previously. After cutting the white wire, solder a length of hookup wire to the end of it and insulate it with appropriately sized heat-shrink tubing. Also, it’s probably a good idea to remove the LED headlight board entirely. This gives you three openings to run your wires out of from the Rovio to our new headlight panel. After you’ve removed the board, you can cut the wires leading to both the infrared LED and receiver. These function as a forward facing “radar” to alert the user if there are any obstacles ahead. We decided to salvage ours by placing them both in the new panel that we will soon be creating. If you choose to salvage your infrared “radar” as well, then remember to solder extension wires between the appropriate leads and the LED and receiver. We actually used some telephone tap connectors (from RadioShack) to extend the three wires leading to the infrared receiver, but soldering should work just fine. Now that you’re finished with all of the internal modifications to the Rovio, we can move on to the circuitry behind this hack.
The Circuit
In order to make sure that we can control our replacement LED headlights through Rovio’s web interface, we need to build a circuit that will detect when the headlights are triggered via the web interface and activate our headlights accordingly. To do this, we’ll use a PNP transistor to switch the ground of our headlight circuit. As you can see from the schematic above, the white wire that we mentioned earlier will be connected to the base of the transistor via a 2.2k resistor, the ground from the power supply board will be connected to the collector of the transistor, and the emitter of the transistor will be connected to the ground of the parallel array of LEDs. If you want to, you could probably add a few more LEDs to this design. Just remember, if you change the number or type of the LEDs, you will have to recalculate the value of the current-limiting resistor between VCC and the positive pin of the parallel LED array. After we’ve reviewed our schematic and we’re comfortable with it, we should be ready to breadboard.
As you can see, there really isn’t that much to our circuit as far as components go. The black and red wires come directly from the power supply board. Our voltage reading was right around 6.5v. Please note that your voltage may vary depending on the charge of your Rovio’s NiMH battery. The green wire was soldered to the white wire inside of the Rovio, and controls whether the transistor lets the ground flow to the LEDs. We found that the best way to test this circuit while breadboarding was to turn on the Rovio and turn on and off the headlights using the web interface. After confirming that the circuit works consistently, you can go ahead and solder the circuit onto some perfboard and connect to the Rovio.
The circuit really doesn’t take up much space on the perfboard. We decided to use the extra space on our board as a makeshift terminal block to extend the infrared LED. While soldering the circuit onto the perfboard, be sure to remember the orientation of your transistor. If you accidentally put it in backwards, you could switch the collector and emitter, burning out the transistor. We mention this only because we actually did it the first time we assembled our board, and we ended up having to swap in a new transistor before reassembling the board. After you’ve assembled and verified that your circuit works, we can move on to assembling our headlight panel.
Drilling and Wiring
On your blank panel, carefully drill 8 holes in any configuration you would like. When drilling your holes, be sure to use a 3/16″ drill bit. While it is actually slightly smaller than a 5mm LED, you can rotate the drill once or twice around to widen the hole. The main thing is that you don’t want to make the holes too large for the LEDs, which, incidentally, we ended up doing. One of them was so wide that we had to change the placement of our LEDs to make sure that they all more or less fit.
I don’t think that I need to get into too much detail here, but the major thing to remember is that the LEDs need to be wired in parallel. Also, be sure that you are connecting cathode to cathode and anode to anode, otherwise the whole circuit just won’t work. After you’ve completely assembled the panel, attach the wires the ground from your perfboard and the VCC from the power supply board to the circuit, and use the web interface to test that the LEDs get switched on when they’re supposed to be. If you decided to salvage the infrared “radar”, don’t forget to attach the infrared LED and receiver to the board in the two holes left over.
After you’ve finished with the drilling and wiring, you should be ready to attach the panel to the Rovio. While it was a little tricky for us, we were able to epoxy the panel to the underside of the front of the Rovio so that it looked like it was vertically mounted.
Now that your Rovio can see better in darker situations, lets take a look at RoboRealm.
RoboRealm
While investigating all of the different things that we could do with our Rovio, we stumbled upon a piece of software called
RoboRealm
. RoboRealm allows you to take video input from any webcam, including the Rovio, and run it through any number of different modules to process the images. After the images are processed, the software can even see if any pre-defined conditions are met, and if they are it will instruct the robot to act accordingly. Combine that visual input with the audio input/output on the Rovio, and you can do some pretty cool stuff. The interesting part about this software is that it
officially supports the Rovio
out of the box. We’ve had a chance to mess around with it a little bit, and as far as we can tell, it seems like pretty powerful software.
We already know all of the cool things that we want to do with this software and our Rovio, but we’re curious, what would you do with it? Leave us your answer in the comments, and if we see something that we find truly inspiring, we’ll do some research, write it up, and post a how-to explaining how to do it. Who knows, there might even be a brand new Rovio and a free copy of RoboRealm in it for the winner too…

The Base-Emitter (NP) junction of a PNP transistor behaves like an diode, in other words current will flow through the Base-Emitter junction (and thus the transistor) when the Base is about 0.6V lower than the Emitter. As pRoFiT pointed out, if the transistor is placed upside-down so the emitter is facing the LEDs, it will function.Also, using LEDs in parallel like that is risky, since the voltage drop for each LED may vary. The preferred method for wiring multiple LEDs is in series with a current-regulated supply. When a current-regulated supply or a high enough voltage isn’t available, you should use a resistor for each LED to avoid problems with different voltage drops.The rest is style nitpicks: there should be junction points where the LED pins connect to their respective “bus” lines, and not that it matters electrically but why is Vcc drawn lower than ground?Sorry for all the negativity, I hope this has been constructive criticism.. <3",

NGX Technologies
sent us this Blueboard LPC1768-H
to play with. It’s basically a breakout board for an NXP LPC1768 ARM cortex-M3 microcontroller (
datasheet
). The board adds a few extra goodies, such as a choice of mini-USB connector or barrel-jack to provide regulated power to the chip. There’s also a clock crystal for the internal RTC and an Atmel 256kb EEPROM chip. This chip has 70 I/O ports, accessed through the pin headers on top and bottom of the board. The 20-pin header to the left is for a JTAG programmer (yes, you’ll need
a separate programmer
). Coming in at only $32.78 this is a very accessible route for projects that require more power than some of
the traditional hobby controllers
. The shipping seems to have come down since
NGX’s last offering
, now it would be under $10 to ship to the States.
The LPC1768 is the same controller from the
mbed that we reviewed
. What’s missing is some of the interface hardware and the boot-loader, but the tradeoff comes with a $66 savings. This is to mbed what an AVR board is to the Arduino, a way to get even closer to the hardware.
There are a few things we think are missing. Most notably, there isn’t a datasheet or user guide for the board itself. The only information available is
a schematic (PDF)
, but that should be enough for those already well versed in working with microcontrollers. There is also a 12MHz clock crystal on the board but it doesn’t seem to be jumpered in case you wanted to use a different frequency. We’re not sure if this is much of an issue, the internal RC oscillators offer a lot of flexibility including operation up to 100MHz.
We feel this is a solid platform that will help to get more people into ARM development because of its low price. Let us know your thoughts in the comments.

Arduino Balloon Tracking

The Ferret is a
high-altitude balloon tracking hardware package
. Created by [Adam Greig] and [Jon Sowman], it uses an Arduino to gather
NMEA
data from a GPS unit, format the data into a string, and transmit that string on narrow-band FM. The project, built in one afternoon, is a tribute to the prototyping simplicity the Arduino provides.
The unit was powered by four AA batteries, using the Arduino’s on board voltage regulator. This provided a bit of heat which helps in the frigid reaches of the upper atmosphere. The bundle above was put in a project box and attached to the outside of the balloon’s payload, then covered with foam for warmth and moisture resistance. This tracking is a lot less complicated than some of the
photography setups
we’ve seen for balloons. It’s also more versatile because it broadcasts the GPS data so that many people can track it, rather than just
logging its location
.

Unfortunately UK amateur radio licenses do not allow airborne use so we cannot operate on normal amateur frequencies or power levels. In the US there are similar frequencies, but you can also use your amateur licenses airborne which nicely gets around the issue.Eric: 500m is about correct for on the ground, but as you guess antenna design (and other factors) significantly alter things. The NTX2 can only transmit 10mW of power, which is very, very little (amateurs will tend to use at least 10W and commonly 100W to 1kW for long range contacts).However, we have direct line of sight to the balloon while it’s in the sky that covers most of the country, which helps significantly; the antenna on the balloon has a radiation pattern that sends almost all the signal downwards with very little going up, which helps, and most importantly we use very sensitive amateur radios with high gain directional antennas to pick the balloon up:http://www.flickr.com/photos/randomskk/4413270817/is Jon modelling the antenna we use.The maximum range we’ve got out of one of these modules with a suitable antenna and receiver was 400km, and at that point the balloon went over the horizon and so became impossible to receive.

Quad-copter Controlled With Voice Commands

[youtube=http://www.youtube.com/watch?v=7nUq28utuGM]
In the video above you’ll see two of our favorite things combined,
a quad-copter that is voice controlled
. The robot responds to natural language so you can tell it to “take off and fly forward six feet”, rather than rely on a cryptic command set. The demonstration shows both an iPhone and a headset used as the input microphone. Language is parsed by a computer and the resulting commands sent to the
four-rotor
UAV.
This makes us think of the Y.T.’s robot-aided assault in
Snow Crash
. Perhaps our inventions strive to achieve the fiction that came before it.

IM-ME Spectrum Analyzer

[Michael Ossmann] rolled out some firmware that makes his
IM-ME into a Spectrum Analyzer
. He met up with [Travis Goodspeed], who authored
the IM-ME flashing guide
, at SchmooCon and spent some time hacking wireless doo-dads in the hotel bar. Once he arrived home the new firmware was just a few coding sessions away from completion. It scans one frequency at a time, displaying the results in a 132 column graph on the screen. He also added a ribbon cable and header to the debug contacts so that future hacking would be as simple as plugging in the GoodFET.
[Thanks

There’s a Hack for that. In fact, there are multiple hacks for that. The plastic that surrounds the something with great potential is pink. One method, which was useful for oversized walkmans and other 80’s/90’s devices, is the CaseMod. old electronics used to have an excess of spare room on the interior. probably to protect the internal components from damage, but possibly even because the designer was thinking ‘you could put your _?_ in there’. i once took a rather large sony walkman and slimmed it down, removing the unnecessary components (ie. tape deck) and gave it a new ductape finish, keeping the important parts(shiny buttons, LCD, tuning coils, switches, headphone jack, battery connections) and slimming it up to the size of a thin wallet instead of >1 thick wallet. once you have the circuitry fully exposed, you have the opportunity to make other modifications. in the walkman’s case, adding internal speakers, or wires for connecting speakers or headphones with severed ends in the future, which i guess i would call a ghetto pre-amp. since this device is already slim, you probably won’t have the benefit of shaving off extra bulk, but you still have plenty of options. For example: DremelMod; (followed by:) SharpieMod; or the Imanartist&iprefertouseatinypaintbrushMod, which is pretty much self-explanatory once you get past the lackofspaces. if you have sufficient equipment and motivation There is also the ‘take it apart and clone the plastic parts by methods such as DIY moldmaking/injectionMolding or just sand/buff/remove the finish and give it your own paintjob, or just completely replace everything that is plastic or pink. this is taking too long and getting real dumb, like the MachineyourownpartsfromMetalsotheCasecostsmorethanWhatsInsideMod. which i end with because i just wasted an hour or 2 writingdumbshit.",

GirlTech’s design and marketing has really annoyed me throughout the years — I put up my brand about the same time they started theirs. I’ve always felt that green+pink on black and lockpicking was a better way to subvert the other girls out there into the computer and hack scene, but I am totally enamored by the hacks that ya’ll have done on this purple quote unquote girly device. And next time I am required to babysit (doesnt happen very often, muahaha.)

The University of Wisconsin is hosting a tutorial on how to
make your own Organic Light Emitting Diodes
. This is so amazingly awesome. We want you guys to make some. Someone make your own matrix and display some patterns on it and submit it. Please. Though we’ve seen lots of uses for OLED screens, we never really delved into the process of creating them. It looks much less complicated than we would have imagined.

No, your eyes do not deceive you, you are looking at a
[Bill Paxton] pinball machine
. [Ben Heck], commonly known for his portable gaming system modifications has finally finished his pinball machine build. We’ve had our eye on it ever since
[Jeri Ellsworth] challenged him
to see who got theirs done first. As you can see, he’s done a fantastic job on the machine itself. He has also documented it fantastically, there’s a build log, a gallery, demonstration videos etc.
[thanks Matt]

Adding An Automotive Cold Air Intake

[Thomas] and a buddy were sucking down a few brews when they decided to
hack their 2001 Chevy Cavalier for a bit better performance
. If they could find a way to bring cooler air to the engine they speculated that they’d see an increase in efficiency. Instead of routing the air intake to a hood scoop, they took off the factory air filter and mounted a cold air filter in its place. PVC pipes were then used to create a delivery path from the front of the vehicle with the output in close proximity to the new filter. They tested their work and discovered a drop in intake temperature from 101 to 48 degrees Fahrenheit at 60 mph, and from 109 to 54 degrees Fahrenheit at 45 mph. Now the sedan runs better and generates more horsepower, all for around $35 in parts.

It’s actually one of the first mods import car guys usually do.There is no increased wear on the engine, aside from choosing a less effective filter. Cone filters are not less effective than a normal square filter, but a k&n filter does filter less effectively than a paper filter. The benefit is that it flows more air than a paper filter.All this mod has done is make the intake flow more air at a colder temperature. Definitely a good mod if you’re looking for a minimal gain in power, but there are much better ways to do it.The correct way is to use mandrel bent aluminium pipe and an intermediate foam filter. That way when you hit a puddle you suck air through the foam filter instead of sucking water up your intake and into your motor.",

"content": "This is a pretty interesting hack.I’d be careful if anyone gets the idea that since a little more is better, a lot more should be fantastic. Many modern engines are often made up of multiple metals (usually an aluminum head with a cast iron block). Metals expand at a different rate based upon their temperature which is one of the reasons a thermostat keeps the engine at a specific temperature. Another big reason for the operating temperature is for the oil. The viscosity of oil changes with temperature. You don’t want the oil to cool too much or friction will increase, the engine will have lower output and a have lower lifespan as you put the block/head through a lot of mechanical torture.Just be mindful of these things if anyone decides to try to hack together something crazy like a liquid nitrogen chiller for the air intake in their car just to see how far they can push it. It’s not like overclocking a computer. Screw it up and you may end up walking. ;)",

Electric-assist Bicycle Uses LiFePO4 Batteries

This
bicycle add-on uses an electric motor
to help you out. This way the motor takes advantage of the gearing normally available to the cyclist. What interests us most about the system is the
DIY battery
work they’re doing. The cells are using
Lithium Iron Phosphate
technology. The li-ion cells you’re used to seeing in consumer electronics are actually Lithium Cobalt Oxide. The Iron Phosphate flavor offers longer overall lifespan, better operation between charges over that life, and improved cold-weather performance. The drawbacks include a 20-cycle break-in period and an affinity for trickle-charging versus faster charging methods.
The 48V cell seen above will provide 30-40 miles of travel between charges. We feel that getting the power plant out of our vehicles is an important step toward energy overhaul but it can only happen if the battery technology makes it possible. Then again, perhaps we’re barking up the wrong tree and should have placed our bets on
compressed air
.

Also, I’m not sure about the discharge rate.. that would scare me a bit if I were using cheap cells in a chemistry that burns aggressively when something goes wrong.If cheap cells I’d probably go with 80 or so, and stick to a 25A controller.

SLA/Lead Acid drops off in voltage pretty quickly.One post mentioned failures in cells/products and they are right, buying from a reputable source is important. One of the reasons to build the battery this way is for the inevitable servicing required as it ages, and being able to swap cells out. The LiPo “prismatic” packaging, or the welded cylindrical cells are not as good for DIY as they are hard solder/weld without right equipmemt. These just take a socket wrench. With the packaged prismatic package batteries, if one cell fails, you are pretty much done – they are hard to fix.Another post asked about the BMS, you can find DIY BMS here :http://www.batteryspace.com/pcbbmscmbfordiy.aspxOne of the reasons I started this product was to develop a new BMS circuit, more on that in a few months…",

The safest way to drive the chain is to drive it with an intermediary shaft and freewheeling mechanism. And for god sakes, use a chainguard!",

Air gets hot when compressed and has to be cooled down to fit it in a tank. Heat is lost, that is, energy is lost. In fact, a significant amount of energy is lost. Then when the air is taken out of the tank, it expands and cools down and the pressure drops, making the motor less efficient.A compressed air system would use up to ten times more energy than an electric motor with a battery.Some special pneumatic motors can remedy this to some extent by having heat exchangers that pull heat from the ambient air, effectively recollecting the lost heat, but the heat exchangers are large and heavy, and not suitable for a motor that has to fit in a car or a bicycle.",

We’ll just say, [Kenneth] really likes clocks. His most recent is a
pure 7400 series TTL based one
, ie no microcontroller as seen in
the past
,
here
,
here
, and
here
. The signal starts out as a typical 32,768 crystal divided down to the necessary 1Hz, which is then divided again appropriately to provide hours and minutes.
As far as TTL clocks go, this is nothing too original; until it comes to his creative button interface. By using a
not as sexy as it sounds
multivibrator, he can produce a clean square wave instead of the figity signals produced from buttons to advance and set the time. Like always, he also provides us with a thorough breakdown of his clock, after the jump.

Xbox 360 Laptop More Laptop-y Than Ever

"Xbox Hacks"

[
"fans",
"laptop",
"xbox 360"
] |
[TheTwoJ] and his friend built a laptop-form-factor Xbox 360. Their
extensively documented process
was inspired by
[Ben Heckendorn’s] work
. The result is a brick when folded up but a good-looking (albeit loud with 8 fans) gaming rig. There’s everything you would expect; LCD screen, integrated WiFi, camera, optical drive, and a full keyboard. These poor saps seem to have spent a portion of their student loan on the build but we understand how easy it is to let your budget get out of hand. They’re trying to recoup through eBay auction.
Take a look at the walk through after the break. If you’ve got the spare dough, you can try your hand at this with our
three
part
series
on building an Xbox 360 laptop.

Tax-exempt Geek Group Hit With Huge Tax Bill

Non-profit hackerspace
The Geek Group has been hit with a hefty tax bill
despite their tax-exempt status. We featured a
boom camera
built by the organization back in November. It is the goal of The Geek Group to fulfill the thirst to explore and create by providing facilities, peer group, and camaraderie that make knowledge and learning not only acceptable, but desirable. In the video after the break you can hear a bit about the organization’s role in servicing donated computers and putting them out into the community, as well as its role in education through groups like the Boy Scouts of America.
This is all done without the goal for profit and accordingly they have attained
501(c)(3) status
with the federal government (we’ve seen
their 990 forms
stating this). To the best of our knowledge this doesn’t mean that they don’t need to pay property taxes, but it does make property taxes ridiculously low (we’ve heard of one cent per acre for non-profit land holdings before). That’s why it comes as quite a surprise when the township slaps a sticker on the doors giving notice of seizure and demanding payment for $47,652.78 in back taxes or the assets will be auctioned off. The entire story, from The Geek Group’s point of view, unfolds in a
video of the quarterly Board of Directors meeting
from last Saturday.
We’re hoping this is just a mistake and can be remedied. That being said, it’s not easy to run this type of operation. It’s unfortunate that the Board of Directors needs to deal with a tax battle in addition to fulfilling the mission of the organization. Good luck to them in navigating the road ahead.

"content": "I’ve been watching the tax war for a while. This boils down to a few different levels of taxes. In Michigan you pay taxes to the State, Local and County governments.These taxes are property taxes on the value of the building and land. Businesses in MI also have to pay PERSONAL property taxes. These are assets other than those covered by the above state property tax. So the contents of the building, machines, vehicles, etc are covered there.The KZOO township assessor used the newspaper to assess the personal property taxes of TGG. So when a few 1.3M$ prototype robots are mentioned, the local assessor decided to tax it at that value. Never mind that they are non-functional and are basically worth scrap value, hence why KUKA donated them.Since the levels of government in Michigan above the local level use the local assessors assessment to set what they are going to tax, it sets off a taxation chain reaction.At this point TGGs legal counsel is of the opinion that there are no legal means to avoid the taxes. It needs to be a legislative solution. So that means Ganholm (governor), Thomas M. George (R)(state senator) or Larry DeShazor (R)(state rep).So I think its kind of up in the air about what is going to happen next.",

Reader [regulatre] has provided us with his furthering of
hacking the OnStar system
in GM cars.
Previously
, we wrote about some initial attempts to gain access to the system that OnStar uses to monitor and control cars called GMLAN. [regulatre] has managed to create an adapter between the GMLAN connector and a standard OBD2 plug, which should allow a number of standard readers to be able to retrieve data.
This method details using a bluetooth OBD2 reader, and passing the data onto a linux machine. It looks as though the writer of this method is looking to integrate OnStar reading and writing into an Android App which currently is an OBD monitor.
We love seeing follow-ups like this, because it puts everyone one step closer to full control of closed devices. As always, let us know if you take any of this in a new direction.

[Steve] let us know about his
MultiDisplay car monitoring system
. Unlike
traditional systems
that rely on interfacing with the OBD-II protocol and existing car computer, the MultiDisplay uses an Arduino and
custom shield
with a combination of sensors; including temperatures, pressures, throttle, Boost, and etc. The data collected can then be displayed on a 20×4 LCD or streamed to a PC with visualization and event recording.
It’s nice to see half a years worth of work finally be complete and presented in such a clean and professional manner, keep up the good work [Steve]

That’s like saying your glasses are “useless” for anything but lookin’ through.And you, @trey… I don’t disagree with your initial comments that reading OBD might be a cleaner approach to monitoring an engine, but does that really make this project “retarded?”Since you can’t see the value in this project, let me explain it to you.(1) “Steve” came up with an idea and turned it into real hardware. That alone should serve as inspiration to all those who post here to crap on other people’s projects, but never seem to get around to building anything themselves.(2) I’ll bet money that he learned a lot about processors, coding, and handling mixed signals. Anyone who attempts to replicate his device will learn similar lessons.(3) Somebody else may look at what Steve has done, and decide that his gizmo is perfect for their non-automotive data collection application. @trey, you can’t use OBD if the article you are monitoring doesn’t have OBD.(4) Somebody may look at what “Steve” has done and decide that *parts* of his system might be useful for a completely unrelated project they are building. If borrowing bits of technology from one system to integrate it into another unrelated system is not hacking, I guess I don’t know what is.Some people bitch about Hackaday not posting enough real hacks, and yet, frequently when something is posted, the author is lambasted for his “retarded” or “useless” project.

I spent 2 years driving round with the MS monitoring my stock ECU to map out actuator trip points, actual AFRs, knock levels etc. Then I modified it slightly to take full control of fuel and spark and tweaked the firmware to work better on my application.Sure it doesnt have 8 EGT inputs, I’ll give you that, but it does have 1 which is plenty in the majority of applications.",

This vehicle is aptly named
the Mondo Spider
. It’s not from some apocalyptic movie, but seen here at Burning Man. Like a lot of
Burning Man
exhibitions
, it was built for the joy of the build and with a rather extreme budget: $15,000. We’ve embedded one of the many videos after the break, as well as a few of the hardware details.
Weighing in at about 1600 pounds this eight-legged horror is much more massive than the
rideable hexapod
we saw a while ago. A Honda 24 horse power V-Twin engine provides the power needed to run the hydraulic legs. It’s designed to turn on a dime, but as you can see in the video, traction can be a bit of a problem. For night-time operation the legs have been outlined in glowing read, as if this wasn’t already frightening enough to terrify the weak-at-heart.

Editorial Note:
There was so much work and time put into this project by
a lot of different people
. We searched around for a picture of the entire team with this bad boy but couldn’t find one. If you’re working on an insane team build, don’t forget to take a group picture that will let you relive the fun times. That’s what
the Copenhagen Suborbitals
did.

Thermos Temperature Meter

We’re always a little surprised by how well a vacuum thermos works, but eventually the contents will cool down (or warm up depending on what’s in there). [Gamesh_] added a temperature meter to his thermos using an Arduino and a temperature sensor. The
original post is in Portuguese
but [Bruno]
republished it in English
.
The temperature sensor has been repurposed from a digital thermometer meant for taking your temperature. Holes for the LEDs making up the indicator bar were melted in the side of the plastic housing. When the hot liquid is poured out at about 0:45 into the video you can glimpse the Arduino hanging our on the other side of the pot and a power cord running off behind the laptop. It would be nice to see this migrated over to a less powerful chip and run from a small coin cell, but we like the concept.

3D Printing On A Much Larger Scale

The end goal of this
giant rapid prototyping machine
is to print buildings. We’re not holding our breath for a brand new
Flintstones
-esque abode, but their whimsical suggesting of printed buildings on the moon seems like science fiction with potential. The machine operates similar to a
RepRap
but instead of plastic parts, it prints stone by binding sand with epoxy. This method is not revolutionary, but hasn’t really been seen in applications larger than a square meter or so. It’s fun to see the things we dabble in heading for industrial production applications.
[Thanks Juan]

If you need thicker walls for things like radiation shielding, you just design them with a large space between double walls and fill the space with loose lunar fill (or build them in a deep hole like an impact crater.",

Eat Your Heart Out IPad

We don’t remember where we read it, but our favorite criticism of the iPad is that is does the same things a lot of other Apple devices do. So why wait until April to get your hands on that functionality? [Alexbates] built his own
iPad clone using existing hardware and software
. This started with an MSI wind that he used as a
hackintosh
. A touchscreen was added to the display, the keyboard removed, and the LCD flipped around. Boom, a tablet running OS X was born. This is different from
others
because [Alexbates] took the time to alter the UI to look like the iPad. Sure, it doesn’t automatically flip the display when rotated and there’s no pinch-zooming. But it does have more processing power and storage space.
We’re more likely to hack our own like this rather than purchase
a device we’re not all that enthusiastic about
.

Normally things like that weigh against your credibility when you call somebody “the dumbest person alive”. Just some food for thought.Also, here are my personal responses to your three points:1: You’re right, this device is definitely made to be portable. It also has one of the finest multi-touch enabled photo viewers so I’m not sure this point is even valid? Perhaps you were referring to the storage limits? Do you seriously need to carry more than 64GB of pictures and music with you at all times?2: Ned covered this fairly well but I’d like to add the fact that THIS IS NOT A LAPTOP OR DESKTOP REPLACEMENT. You talk of wanting to connect a keyboard to it like it’s a very vital thing, but why would you want to carry around a bulky keyboard with you everywhere if this is meant as a portable web browser?3: There’s a 3G version if you didn’t know already, so I’m not sure what magic device you think wouldn’t have the exact same limitations.",

However, I do feel it’s got a market, even if its small. I also feel there are many many people who think they need one and most definitely do not. To be honest, I’m still torn on whether to buy one or not. The data plans for 3G are VERY appealing as I can just pay for what I need and there’s no contract BS.

What’s missing in all of the “OMG I can’t share with my friend” rants above is the question, “Well, what system is your friend running that you want to share with?”. In most common use cases, you can just attach the files to an e-mail and send them immediately using a common, well-supported paradigm. If you want to share a whole bunch of pictures or something, you will just upload them all to facebook or myspace or one of any number of online “locker” services and send your buddy a link.That’s one of the reasons the limited local storage for these is not a hindrance – when you are connected to the internet 24/7 you don’t NEED massive local storage.Frankly, we’re coming quickly to a day where if my friend doesn’t have a device or system that I can somehow connect with via the internet, local network or bluetooth, he’s the unconnected bumpkin, not me.",

These plugs are cheap, easy to make, and work well
for measuring the moisture content of soil
. The Cheap Vegetable Gardener came up with this method in order to add automatic watering to
an automated grow system
. Plastic tubing is used as a mold for Plaster of Paris. Once the plaster has been poured, two galvanized nails are inserted. These are won’t rust and work as probes, measuring the resistance of the dried plaster (gypsum). When inserted into the soil, the moisture content within the gypsum will fluctuate along with the soil. As moisture rises, the resistance between the probes falls, which can be monitored by a microcontroller and used to trigger or stop a watering system.

It is basically a nice compact layout for an
Atmel Atmega 328 with a wireless module
. Fully compatible with the Arduino IDE. The JeeNode is available in kit form, but also all schematics and CAD files are available to download. It looks like they are mainly using it for home monitoring and control. So far we’ve seen them put a temp sensor, power metering, and IR LED modules on their
flickr set
.

Intense Kit Turns Wacom Tablet Into Cintiq Clone

[Lesa Wright] just started selling enclosure
kits used to convert a Wacom tabet into a Cintiq clone
. You need to start with your own Wacom tablet, there are
kits for four different models
. You’ll also need to
track down some other parts
: a compatible laptop LCD screen, controller kit, and some cable extenders. From there, the kit takes over, with several pieces of laser-cut acrylic needing to be glued together properly, then a surprising number of spacers need to be cut from foam board in order to mount everything..
The kits come in at around $225. That might seem a bit steep since you need to bring your own electronics to the party, but have you checked out the price of
the original Cintiq
? You can expect to drop about twelve-hundred bones on a ready-to-use model. Before you take the dive, you should
watch their collection of assembly videos
, it’s quite a process.

"content": "The pressure sensor is in the stylus/pen, which normally would require batteries or a usb cable. Wacom uses electromagnetic resonance technology, which is why the stylus/pen doesn’t require batteries. A bit of weak energy is triggered in the stylus/pen’s resonant circuit by the magnetic field generated by the sensor board. The stylus/pen’s resonant circuit uses that energy to return a signal to the sensor board. Which is also why you can control your cursor by hovering the pen above the surface of the tablet and the sensor board can track it. (That is the gist of it, I read an article on this the other day when I was trying to explain it to someone. I all but copied and pasted the explanation. . .(I am reading the article again and the part about the pen is almost word for word, except they make it sound prettier.)I recommend trying it yourself, just run whatever software you draw in and hold the stylus/pen in a way that a finger is on the nib(palming it works for me) when you have your hand close enough to the tablet to control your cursor apply pressure to the nib. It can be fun to trick your kids or the less tech savvy people you know. Once when my brother was visiting and he brought my Nephews and my Niece. I placed a thin silkish cloth thingy I found(previous tenants left it.) over my tablet, and taped my stylus/pen under my wrist, but high enough to be able to press the nib by slightly bending a finger(hidden the sleeve of my hoodie) and I had them convinced I had the power to control computers with my mind. I wish I had my Leap Motion controller then.If anyone’s interested in the tech I will link it. It goes into way more detail about the technology. I won’t link unless someone actually wants to read it though, I feel spammy when I do that on someone else’s thread.",

Besides being great for all sorts of computer graphics tasks, it actually enables me to draw. I’m a pretty good graphic designer, but no matter how hard I try, I could never draw on paper. With a Cintiq and the right software, I’m slowly getting somewhere with comic illustration.I would have loved to have done it cheaper though, this looks like an interesting idea, but it needs a bit more polish.One downside to this hack is you’re not liable to find many laptop LCD panels with the same graphic quality of the panel in the Cintiq, and you definitely won’t find one with that has a 180 degree viewing angle on both axis. (Something to do with a radial polarizer or something)But hell, if you just want a high quality digital sketchpad, this certainly looks like the way to go.Ugh, when I saw the new Cintiq 21UX last week I nearly cried. ;( I have the second version, the one with the modern Wacom logo.

Flip-top GameCube Portable

"portable"

Here’s another home console made into a portable. [Techknott] built this
shiny GameCube handheld
. You may remember him from his work on
a portable Dreamcast
and the
wireless Xbox 360 interface
. This time around he’s mirrored the finish; a good idea in concept but even his demo images are already plagued by smudges. But if you can keep your digits on the plastic buttons this makes for an eye-catching design. One part that we love is the flip-top screen that hides the optical drive. This is a much better solution than the exposed lens we saw on
[Hailrazer’s] GC portable
. As always, video after the break.

RFID Reader For IPhone
|
Mike Szczys
|
[
"iphone hacks"
] |
[
"mifare",
"openframeworks",
"rfid",
"serial"
] |
[Benjamin Blundell] built
an RFID reader for the iPhone
. A
jailbroken iPhone
connects to this project box by patching into a standard iPhone USB cable. Like in
past iPhone serial projects
, [Benjamin] is using openFrameworks for the software interface. Right now this reader only detects low-frequency tags but he’s working on the code to read
MIFARE tags
as well. See the magic of a tag ID displayed on the screen in the video after the break.

Sometimes your project needs a lot of non-volatile ROM, right on cue [Matthew] let us know how to not only connect, interface, read, and write to
SD cards with a PIC
over serial, but also how to do the above mentioned with
an old PATA HDD
. For those without a PIC/serial connection don’t fret, [nada] let us know about his
Bus Pirate SD card hack
, of which our personal favorite part is the creative use of an old 5.25″ floppy connector as the SD card socket.

[Adam] wanted a stereo that could stand up to rain and keep sand out. He ended up building this
beach stereo out of a cooler
. The cooler’s already made to be water tight. He cut holes in the front and back for marine speakers and added a water-tight bezel and cover for the controls on the deck. Inside you’ll find a marine battery to power the unit. Now he and his friends can rock-out even in poor weather thanks to this portable and rugged unit.

The CD player did ok BUT as a metal detector nerd, the salt air is an unbeatable beast. My suggestion: zinc anode blocks from a marine supplier for boat motors. These little guys “attract” the naughties that eat anything metal on the beach (mainly in the water) and should be cheap. Quick GOOGhttp://www.jamestowndistributors.com/userportal/siteMap.do?action=map2&catId=90has some so ya can get an idea. I would personally just rip some off an old boat motor myself, but food for thought. Also dielectric grease for your metal contact hardware, as you will see the copper will green in no time, and silicone caulk in the mounting brackets. Finally lil dessicant packets from shoe boxes and letting the beast air out properly after you fresh water spray it after beach use and you should be good to go man. Mainly what happens is salt film clings to the staticy CDs and is heated up by the laser and forms a nice salty mist inside the CD player that first blinds the lens repeatedly and then rots the ribbon cables plastic film causing shorts. This can take months or years though so you may be good. Best of luck my friend.",

Easy IM-ME Flashing

[Travis Goodspeed] wrote
a guide to firmware flashing for the IM-ME
. He’s using a
GoodFET open-source JTAG adapter
that he designed to do the programming. This is really taking [Dave’s]
work on the device
and running with it. The end goal being to develop an operating system for the device. If you haven’t read the past articles, once hacked this becomes a development board for the
Chipcon CC1110
processor with keyboard, LCD screen, and wireless communications included.

Steam Powered Tank
|
Mike Szczys

[
"Toy Hacks"

"rc",
"steam",
"tank"
] |
This
steam-powered tank
is really something of a steam-electric hybrid. Steam provides the locomotion, but an electrical system provides the remote control and steering. A full boiler will provide 10-15 minutes of operation which you can see in the video after the break. Before you leave a nasty comment: Yes, we realize this project is from several years ago. It’s new to us and the completion date doesn’t diminish the novelty of this well-executed build. This is
the quality
and
uniqueness
we’re used to seeing from [Crabfu].

The battery exists to start the engine, and to provide brief support of electrical systems when the engine is not running. It also serves to provide surge current, not unlike a big-assed capacitor would. It is not, however, a primary electrical source.If you think it is, turn on your headlights or AC blower without the engine running and let me know how long it lasts.I thought it was understood that a steam-powered generator on an RC tank would have to have some electrical reserve, like a car. I guess I can’t assume that what is obvious to me would be obvious to you.Second, I would remind you that this article is about a tiny steam-powered tank, not a model aircraft. I am not worried about gliding back my toy tank after the fuel runs out.Finally, if you are really worried about a boiler being damaged by running dry, the worst idea is to make your safety mechanism reliant on the state of a radio link or the unknown condition of a battery. That’s not fail-safe. A far better approach would be to use, for example, a bimetallic coil to close a damper (and choke the flame) if the boil temperature should get too high.As to your comment about “stupid” ideas… The only thing “stupid” around here is your approach to interacting with other human beings.

[Aaron] calls
this project
“Stochasticity”. It uses two sponges as a musical interface. The performer wears a wrist strap and then draws on the table with water from the sponge to play different notes. You really need to watch the video to fully understand what’s going on here.
We’re guessing that this is Arduino based since some of his other projects are as well. You can try out another quick project of his,
an Arduino electromagnetic field detector
. Check out video of that after the break.

There’s something viscerally pleasing about simple solutions. [Kip] came up with one in the form of
a scratch controller
. The spindle from an optical drive is used to hold a CD in place, which acts as the LP for scratching. The sensor from an optical mouse is mounted upside down below the CD and detects the rotation of the disc. From there it’s just a matter of setting up your software to get the reading from that mouse. He’s had some trouble finding disc surfaces that the mouse sensor will read reliably. We’d recommend trying some of those stick-on inkjet CD labels.
This is similar to
a scratch controller we saw in 2008
. That one was actually repurposing the IR encoding from inside of a mouse. We’re not sure which method would work better, but either controller will make a nice addition to a
Flexi Knob
setup.

Sure, the video above is not worthy an Oscar, but is it his hack-skills or his presenting-skills that is the primary concern on a blog like this?Second, just because a hack is simple/easy to implement and recreate doesn’t automatically mean that is bad/not a hack/not worthy of this site. Some of the greatest inventions are also very simple. Thinking out of the box and repurposing the components of everyday things is, IMHO, an extraordinary feat not to be ridiculed with like this. You guys are complaining that he’s not even using an Arduino, I could just as well complain that you are noobs for wanting exactly that. Why not build your own uC with ICs from the 74- and 4- series?It’s a matter of perspectives and I believe it is a good thing that we can abstract ourselves from the very lowest stuff nowadays. Look at the impact of the stuff from Arduino, Sparkfun, Phidgets etc. Look at all the stuff that has been created with it, look at all the creativity is has enabled to be channeled into real stuff. But no, I guess it is not haXXor enough for some.",

Update: Nintendo DS Camera Control
|
Mike Szczys

] |
[
"Nintendo DS",
"open camera control",
"open source"
] |
All of the juicy details needed to control a camera from your Nintendo DS are now available at
the Open Camera Control project
. This is the descendant of [Steve Chapman’s]
setup from a few years ago
. The system has been polished up and has seen many feature additions. It’s been used in movie production and works with a wide range of cameras.
Start by
building your own interface cable
using an AVR microcontroller running the Arduino bootloader. Finish up by
loading some open source software
onto the DS to add a cornucopia of shot options.
[Thanks Pops Macgruder]

But this is a slick piece of software, which I think is the real hack to showcase here.",

There are many people using the standard 3 pin N3 shutter release cables to trigger Canon Cameras, but using the USB port allows a lot more flexibility.This site seems to hint they think it would be easy with a Vinculum module and PTP. I call BS on this. I have the Vinculum module, have looked at the gphoto2 source to see how ptp works, and am convinced it’s not a simple task. I think it would take me at least a few weeks to get the details worked out. I’ll probably do it someday when I’m not too busy, but if someone else knows of people doing this already I’d love to use their work as a starting point.The thing is it would be even better to use the Canon priority SDK protocols since they allow more flexibility than PTP, but this would require sniffing the USB port and decoding their protocol which is even more work than PTP. I’ve done a lot of searching, but I haven’t found anyone who has done this yet.",

If you download the current docs for the canon SDK (search rapidshare / megaupload for “EDSDK-API.pdf”) you will find that Canon publishes the SDK for an extremely few OS’s and is X86 only. So any control app using Canon’s SDK would have to be developed on WinXP or MacOS. Neither of which run on the ARM, Pic, or ATmel.Perhaps it would be possible to make an app using the Canon SDK which iterated through all possible variations of calls in the API and then construct a new API based on the observed USB traffic. Just writing that sentence annoys me but it’s probably less work than what these developers went through using the gameboy.Another possibility is to use a compatibility layer like wine (but as far as I know there is no wine for Android and a lot of reasons why it would be difficult to implement). Still Android would be an attractive platform for thisThe last possibility I can think of is an iPhone app but I do not think the Canon SDK for mac could be wedged into service for the iPhone/iPad (being that it is for Intel macs only). Does make me wonder what sort of effort porting the existing gameboy apps to the iPhone/Android and combining the USB functionality would be.",

Acutally it can work with any camera wirelessly as it just maps a remote USB device wirelessly as a local device..But one issue of this is the battery power supply. It seems 2AA batter can not drive the embedded linux system and this is important to make it a small device used outdoor..",

Hardware Jailbreak Eases Reboot Pains
|
Mike Szczys
|
[
"iphone hacks"
] |
[
"blackra1n",
"ipod touch",
"jailbreak",
"Tether"
] |
This
device can jailbreak an iPhone
. It doesn’t require a computer and it can either reboot a phone that was one-time-boot jailbroken using the blackra1n exploit, or jailbreak a factory fresh unit. We wouldn’t say this solves the tethering problem caused by blackra1n (needing to return to a computer to reboot the phone), but it certainly does ease the pain. We saw some info about the board layout but no parts list or firmware. See the demo after the break and leave a comment if you have more information on the parts or code.

We can only imagine how amazing
this coffee burning car
smells at it speeds down the highway at a maximum of 60mph. Don’t jump out of your seat so quick to get your own, while the idea sounds fantastic, the mileage will bring you back to earth rather quick. At 3 miles per kilo of coffee, it can turn that £36 210 mile trip into one between £910 and £1,820 with a stop to re-bean-fill every half hour!
Still, the Car-puccino is an amazing conversion, and we’re getting closer and closer to Back to the Future’s
Mr. Fusion

50MHz To 100Mhz Scope Conversion

[Ross] is the proud owner of a 50 MHz Rigol DS1052E oscilloscope. He’d like to have the 100 MHz version but the $400 difference in price puts it out of his reach. After some extensive poking around on the PCB and pouring over datasheets, he managed to
reverse engineer the design and upgrade to a 100 MHz version
. This is as easy as desoldering one capacitor to deactivate a high-pass filter present in the lesser model of scope, unlocking the faster potential of its bigger brother.

Normally a 50 ohm terminator is used at the end of each BNC cable when coming off of a single signal source, I didn’t know that when I constructed my home-made cables. When testing with probes, that doesn’t happen as much. I think there’s really no way around that because I’m essentially testing the scopes response using itself.My concern is that there may still yet be some filter somewhere on the underside of the board, because another person with a 100 MHz model found the same filter on his board. There are two vias travelling to unknown locations, however, which may enable/disable the filter by some command. If there is another filter, it’s curious that the bandwidth response seems to be exactly what it would be in a 100 MHz scope already.The internal model number may be changed with NI VISA commands and the firmware for the Mixed-signal version (also identical hardware) is out in the wild too.

They’re graphed, but ignore the second time I tried that as I didn’t use proper cabling. Either way, the filter is in a place where it won’t affect the scopes operation, unless you can explain otherwise. It’s right between the ADC buffer and the amplifier.. the ADC in an oscilloscope has no reason to see a filtered signal that I know of.I hope someone tries this and plots the output to a 200 MHz scope, as someone at the EEVBlog forums has already done this and plotted the 50 MHz scope output.

[Jeri Ellsworth]
made this silicon inverter at home, by hand
. It took her two years to get the process figured out and achieve something we didn’t think was possible. The complexity of manufacture, and the wide range of tools and materials needed seem insurmountable but she did it anyway. Her
home chip fab Flickr set
is well commented and details her work area and part of the processing. If you’re hurting for more check out her 40 minute Metalab talk which we’ve embedded after the break.
If her name sounds familiar but you just can’t place it you may know her from
The Fatman and Circuit Girl
. We’ve also featured some of her hacks, such as
her Pinball challenge
against [Ben Heckendorn], and
her giant Etch-a-Sketch
.

[Matt Kemp]
remade this super 8 film camera into a synthesizer
. Inside you’ll find a light sensor pointed through the lens. This way, zooming, focusing, and pointing the lens elsewhere will change the sound. He also refit the original controls to monkey with the output. Turn your speakers up when you watch this, your co-workers will love you for it.

Game Glove Learns Your Weakness

"glove",
"paper",
"rock",
"scissors"
] |
[Steve Hoefer] pulled together a great hack for the friendless. This
glove will play a heated game of rock-paper-scissors
against you. [Steve] realized that the middle and fourth fingers are all that need to be monitored to decide which of the three signs you are making. He used flex sensors on the back of these fingers as an input. There is also an accelerometer to judge the three shakes that lead up to the shoot.
The small screen you see displays what the glove chose and is a hack in itself. This idea adapts from
an Evil Mad Scientist project
, using three sheets of acrylic etched with the different icons and edge-lit with LEDs. All of this, along with a speaker and scoreboard, connect to an Arduino. The icing on the cake? [Steve] coded an adaptive learning algorithm that observes your playing style to gain an advantage.
See this in action after the break. Once you’ve mastered rock-paper-scissors you should consider building
other glove-based
peripherals

Follow along with [Victor] through the journey of building a
life size replica of R2D2
. While you may not be able to scrape too many specific details from the video, it is still great to see the project progress from his first cut to the finished product as well as some fun little outings. His R2 looks absolutely impeccable and he deserves dome credit for taking it to places to show kids. We would have probably just found interesting ways for it to
bring us beers
.

Will This Mouse Get Me Kicked Out Of The Coffee Shop?

"Peripherals Hacks"

"creepy",
"mouse",
"taxidermy"
] |
This [Dwight Shrute]-esque project will let you
try out your taxidermy skills
. Apparently you can acquire a ‘wetware’ mouse fresh or frozen from pet stores. We just need to wait until fall when our pantry is visited by the less-domesticated variety.
A travel-sized optical mouse acts as the replacement guts. Some creative dremeling brings the plastic housing down to a more acceptable shape. The furry bits need to be processed using
the mouse taxidermy guide
before they are fit over the electronics. What you end up with is a creepy peripheral that nobody wants to use.

It’s easy to throw around the accusation that you waste time throughout the day. Now you can prove it by reviewing everything you did on your computer, all in just one minute. [Dan Paluska] ground out some
code to take screenshots and assemble them into a video
.
His script
ties together the open source tools
FFmpeg
,
ImageMagick
, and
scrot
. It takes a snap every 15 seconds in a 10 hour period for a total of 2400 frames. He even outlines the process to automatically upload these clips to YouTube. Just remember, if you’re doing
something naughty
, there’ll be a record of it.

Add A Clean Room To Your Workshop

"Tool Hacks"

[
"clean room",
"mdf",
"shelving"
] |
I Heart Robotics has posted
a guide for building your own clean room
. They’ve been clever with their materials, starting with heavy-duty shelving to provide the framework. We like that idea, it allows you to position your workspace at whatever height you desire.
The side walls are MDF painted with white enamel. Light, power, and tools are mounted to these walls. To keep things clean, a ventilation system uses a vacuum filter and 12V fans to keep filtered air moving in and dirty air out.
Maybe now we’ll be able to
pull off that window hack without killing our hard drive
.
[Thanks Mawitö and Ciric]

You could use bag filters from upright vacuum cleaners inside the pipe for extra filtering in case there’s a problem with the external filters. Moving the vacuum motors away from the bench and piping the supplied air will greatly reduce noise. Putting the motors in old speaker cabinets will reduce noise further but creates particulate problems.For a glove box make the front hard, put some needle point frames on the hard front to hold gloves, get some Obstetrical Sleeve Gloves, [a big animal veterinary supply will have them] and clamp them in the needle point frames. A manometer made out of clear plastic tubing and colored fluid will help monitor the positive pressure inside your glove box and tell you if there’s leaks or the filters are clogged.",

This is so that if any air would attempt to go in the hood (Surpass the positive pressure) the region of negative pressure in front of the entrance to the clean area would be likely to suction the air.Our hoods also employ a much larger air transfer rate. Their motors use an extremely high flow rate to replenish the air within the hood almost constantly and maintain a 0.2+ Psi differential to atmosphere (The Clean room Surrounding).A little gowning information. You do not want to be working with bare hands in this kind of environment, the amount of shedding that your skin does will tarnish your work extremely fast. We use double gloves, the first pair is put on outside of the hood, where the second is removed from the wrapper and applied after the hands have been inserted into the hood.A fluorescent UV lamp is also a good addition if there is any concern about biologicals in the cabinet.

[Yoshi Akai] built
a sequencer that is part steampunk, part injection molded plastic
. The LEGO sequencer MR II has eight steps in a loop that is manipulated by adding the colorful blocks to a green base plate. Each color corresponds to one particular sound which can be modified by building skyward. On the other side of things he’s added a beautifully crafted control area for knobs and switches. We didn’t see much info about what is inside the device so, watch the clip after the break and then feel free to start the speculation in the comments.
This is a similar concept to the
coin sequencer
. From the picture above it seems the blocks have been altered and perhaps
use light to identify the different blocks
.

[Brian] wrote in to show us a site he’s been working on for a while. He’s been building a
tube clock database
. We didn’t realize there was actually a big enough draw for such a site, but we have to admit that we spent more than a few minutes browsing through the different clocks. There isn’t a ton of data for each clock, but there are links to individual project pages wherever available. There is also a growing amount of information on the different components themselves, so submit any data you have that he’s missing to help flesh it out.
The video above wasn’t chosen for any reason other than it is quite stylish.

Who needs expensive acrylic based, microcontrolled robots with only a few sensors available when cardboard and an Android cellphone will work much better for much less in cost! The team over at Cellbots have
done just that
. While they did cheat a little by using a laser cut cardboard for exact measurements and including an Arduino to control the servos, they certainly attained their goal of “cheap” (assuming the already had the cellphone). We’re just wondering why it took them
4 weeks
for a little
CAD
and
code
.
Regardless, one idea that immediately comes to mind is
thousands
hundreds
a few little cardboard
swarm bots
ravaging homes everywhere, just don’t step on them.

Many robot kits greatly exceed the price of the G1 + the gear they used. I would also point out that they used Serial for communication, making it possible to connect to a variety of devices. They just picked what they had on hand. With Android picking up market share, I’d say having an android phone on-hand (as I do) is hardly as exotic as UAV components.",

That’s a lot of LEDs, and a little bit of glass cleaner. [Tobias]
spiced up his IKEA coffee table by adding 6144 LEDs
. This is a larger realization of
SparkFun’s LED coffee table
which used 64 8×8 modules. [Tobias] sourced three
display boards from Sure Electronics
for a total of 96 8×8 modules. These boards are addressed through a serial interface; four serial lines for each board but a shared data bus for each of the row select pins and the data/latch/clock pins. This method uses 19 of the 20 pins on the Arduino that drives the display. After the break you can see a demonstration. If this is more than you need there’s always the
112-LED
and
81-LED
table projects that can produce a full color range.

Dr. Boardman’s Color Conundrum
|
Mike Szczys

[

[
"atmega8",
"color conundrum",
"led",
"rgb"
] |
We feel like trumpets should be sounding. Someone took the overused project of connecting RGB LEDs to a microcontroller and produced something useful. [Paul] created
Dr. Boardman’s Color Conundrum
which works much like a simple mechanical coin-op game you might find at a carnival. When switched on, a random color is displayed by the ping-pong ball covered LED on the left. The player then manipulates three knobs to color-match the two lights.
Inside you’ll find a minimalist set of hardware. An ATmega8 polls the three potentiometers and uses them to mix the appropriate user color. Everything is wired-up using prototyping board and draws power from two AA batteries. He’s using a random seed stored in EEPROM and increments it every time the uC boots up. This keeps the input color different for every game.
Fun and simple, it’s not going to
make your guests marvel at the complexity
but [Paul’s] come up with a unique game that we think has marketing potential.

[Jake Howe] brought his 1984 Mac up-to-date by
cramming new guts inside of the classic case
. The goal from the start was to run OS X Snow Leopard on the machine without altering the externals. He heated and formed acrylic around the original CRT screen to make a bezel for the replacement LCD screen. The floppy drive slot was used to hide an SD card slot and USB port. The original serial port openings were even outfitted with their own USB ports. In the end he did a brilliant job of hiding the
Hackintosh
mini-ITX board and components inside this iconic enclosure.

Like many projects, this one started with a harmless question. “Will lava lamps work in a high-gravity environment such as Jupiter?”. Well, as it turns out, this harmless question was not so easily answered. The only real solution was to test and prove for sure. To do this, [Neil Fraser]
built a centrifuge in his living room
. At 10 feet across and roughly 50 kilograms, this is no small toy. The end with the lava lamp is set to pivot, so at a stand still, it is positioned vertically and at full speed it is positioned horizontally. The whole process is recorded on video for proof. So, does a lava lamp work in high gravity? Watch the video or read the article to find out.

For one of the principles of a lavalamp, as I understand them, is that there is a heater at the bottom causing some interesting flows as the liquids react to the temperature change.As far as I can tell their experimental setup, though interesting, does not take the heat effect into account and therefore this experiment does not answer the important question whether we can decorate our household on Jupiter with these lovely items.Nevertheless let’s not despair as this setup can be used to test whether hamsters can run a treadmill on Jupiter.

When it’s denser than the water, it will sink at a rate proportional to the force applied. When less dense, it’ll rise at a rate proportional to force.pff, He is using a 1/4″ connector. While this is an audio connector, it’s a fairly large one, and is often used in setups that need 360 rotational freedom. Sure, you’ve got a chance of blowing a fuse, but there’s really no better way to do this without spending a lot of money. As long as he’s watching it (and who would run a centrifuge without watching it?) it’s reasonably safe.",

Don’t Worry Occifer, There Is No Blood In My Alcohol!

[Daniel] wrote up a quick tutorial on
interfacing with the MQ-3
, or better known
Breathalyzer from SparkFun
with Arduino. While we would have used perhaps an
op-amp/comparator
based system and kept it in a much
smaller package
, the idea was so quick and simple and enjoyable we hoped an article might keep some hackers from drinking and driving.
[Thanks CletustheYokel for pointing out our silly category mistake.]

137 Years Of Popular Science Online Free

137 years of the magazine Popular Science
are now being hosted online by Google. You can peruse at your leisure, though you’ll have to search by keyword. We don’t see a date or issue browsing option. The cover art alone is worth your time, even if you’re not a fan of the articles. Many of us have fond memories of our childhood being influenced by the contents of these pages.

Time Delay Door Alarm
|
Caleb Kraft

[
"classic hacks",

"alarm",
"security"
] |
Ever accidentally left your front door ajar and had a pet escape? [BlackCow] came up with a
simple solution
to this problem. The circuit is fairly rudimentary but a great example of using the basics to get the job done. Now, instead of having an alarm that sounds as soon as the door is open, he has a 30 second delay. This helps avoid the “boy who cried wolf” effect also known as the “vista security warning” effect of being bothered too many times for a non issue. We also have to say that we like his taste in blog layouts.

Strobeshnik, An HDD Clock
|
Caleb Kraft

[

"hard drive",
"hdd",
"strobe"
] |
Strobeshnik
is a somewhat different twist on the
hard drive clocks
we’ve seen in the past. Though still technically using a POV effect, the Strobeshnik displays the numerals instead of a line. By altering strobe timing of an LED behind a platter with the numbers cut into it, he can display whichever number he wants. We think this is pretty slick.

But then you’d probably get a new problem, because the barriers would cause dead spots in the picture, where you can’t display anything. Maybe you could attach the barriers to the disk, but that in turn would create a whole lot of new problems.As for the balancing of the used disk; maybe you could write a script to figure out the optimal distribution and spacing of the digits, to both maximize the shortest distance between the cuts, while maintaining the center of gravity of the disk. While the optimal solution might be an NP-complete problem, I think it would be possible to find a satisfactory sub-optimal solution with a fairly simple algorithm.The distribution and non-uniform spacing of the disk could easily be accounted for in the software.",

When we saw [merkz]
use of an Arduino
to produce
lucid dreaming
we were quite shocked. Unlike typical setups that just flash a light through sleep, his system monitors eye movement through electrodes and is able to send the data to a computer for graphing and analyzing. The only problem being we couldn’t find a circuit diagram or code.
Not ones to be shot down so quickly, a Google revealed
this thread
on making ‘Dream Goggles’, which was really a
Brain-Wave Machine
based on the parallel port. Some modifications of an
ECG collector’s electrodes
using sound cards, and you could have your own lucid dreaming.

Most desktop PC power supplies connect the serial, parallel, and USB ground pins directly to power neutral at the wall outlet. This is still safe if your home is wired properly, but lots of outlets aren’t wired properly and if you happen to try this with one of those the results can be very serious.Most medical equipment that involves connecting highly conductive electrodes to your skin uses really paranoid isolation techniques because the companies that make them really, really don’t want to be blamed for killing you.Laptops are reasonably safe in this regard since they can be isolated themselves, and even when operated from wall power they tend not to have floating signal grounds (though not all do; this should be checked). This isolation isn’t medical grade but will still probably save your life if the electrician was in a hurry and swapped hot and neutral on the outlet you’re using.",

Never use mains power for such devices.As far as the device itself, this one will work. It is monitoring the nerve impulses to the eye muscles, and if there are a lot of motions happening then it can be assumed you are in REM sleep.There is a easier way to induce lucid dreaming. For the next several weeks just repetetively ask yourself “Am I dreaming right now?”. Once the habit of asking this becomes routine you will accidentally ask it of yourself while you ARE dreaming. The moment that happens you will realize it and be able to take control of your dream. No equipment needed. Works like a charm!What this could be used for however, is an alarm clock that can monitor your sleep cycles through the night and in the morning pick a time where you would wake up refreshed rather than groggy from waking at the wrong point in the approximate 45 minute sleep cycle.",

There are two places you do not want to risk noticeable current flow, the chest cavity and head. This is why you will see experienced people touch the possibly hot circuit with one hand while holding the other behind their back — as long as the current doesn’t flow across your heart it’s very unlikely to kill you.Unfortunately, voltages as low as 40V and currents as low as 20 mA can kill you if they hit you wrong in the heart or brain. You might sensibly risk getting a shock on occasion but you absolutely don’t want it going through your heart or head.And that’s why when you hook metal thingies up to your skull and hook them up to electronics, you want to be super careful about what’s on the other end of the wire. It’s not like you’re hooking them up to your fingertips.@therian, um, what?",

Reader [Jan] came across a website all about
building your own video projector
. We’ve linked to five of the best projects for 2010 but there’s a ton more information if you dig a little deeper. Our favorite so far is the
GohtanBox v3
and it’s giant LED panel that serves as the projection light.

It’s just cheaper to repair or mod a used commercial projector thes days. Bulbs are available cheaply these days fromhttp://www.lumenarc.co.ukso you don’t have to buy the whole lamp.

The secret is in using modern lamps, the correct fresnel lenses and large aperture, well corrected projection lenses capable of covering the full LCD panel. These lenses are best recovered from epidiscopes or epidiascopes which have a large aperture and the coverage due to being used to project images reflected from non-transparent media, i.e. usually paper of A4 or slightly bigger format.These lenses where produced by many past makers such as Aldis in the UK (18″ FL @ f1:4.5 or F1:4)and Beseler in the US (450mm or 18″ again around F1:4). See also Leitz among others.I have two Beselers that I purchased with the idea of building my own projectors but never used them because I just do not have the room to use such large projectors and find 42″ tv’s adequate.These lenses are also suitable for lower power “richest field” telescopes using high quality, wide field, ex-military surplus eyepieces (Rank Precision Industries Fighting Vehicle sighting systems (Chieftain/Challenger Tanks)).If anyone is interested these Beseler lenses are surplus to my requirements.",

Google Unveils API To PowerMeter
|

"PowerMeter"
] |
Google’s tentacles continue to wrap around every portion of our lives with the addition of an
API for their PowerMeter software
. The
PowerMeter tool
works with smart electricity meters to monitor and display power usage in the home. This will allow manufacturers (and hackers alike) to design new devices with the Google interface in mind.
We’ve got an old-fashioned power meter with a spinning dial and no blinking LED. This means we can’t
monitor that blink
to add our own PowerMeter interface. But if you do have an easy way to grab data from your meter you can
design a home system
that takes full advantage of Google’s tools.
Ok, who’s going to be the first to
have their Google PowerMeter-compatible hack featured on Hackaday
?
[Thanks Juan]

Using Mindflex To Shock The Heck Out Of People

[
"Toy Hacks"

[
"game",
"mindflex",
"shock"
] |
We love to see eloquent hacks but this isn’t one of them. [Aaron] and his fellow sadists are
using a Mindflex game with an electric shocker
. If your brain is idle you’ll be fine, but too much activity inside the noggin and you’re in for nasty shock to the arm. Take a look at the video (bleeped but probably NSFW) after the break.
We’ve seen the
Mindflex
before, they’re using its interface in the same ways we’ve seen the Force Trainer used, by
tapping into the LEDs
. The
shocks are provided by a Qkit
, so hopefully there’s enough engineering behind it to keep the ‘contestant’ safe.
Hey, isn’t that

Home Cinema 3D (or Just Tick Off Theatergoers)

After a visit to the local theater and discovering the use of IR 3D glasses (for films such as Avatar), the team over at Furrtek
wondered how they worked
, and more importantly, how the glasses could be manipulated to tick off audience members. While the original intentions seem a bit childish, they did mention that their final setup could also be used for a home cinema with IR 3D glasses.
Onto the good stuff: the glasses receive IR light pulses timed with the movie to black out the appropriate eye with the appropriate frame and producing a 3D effect. With the use of
IR Investigator
the team grabbed said timings; it was then simply a matter of building
their own IR projector
, and
bringing it back to the theater to annoy the crowd
setting it up for their 3D home cinema.

Then try doing this with the glasses the other way around, you will notice at 90 degrees rotation that when you close an eye one of glasses turns black (one black for each eye)",

Monocle Fixes Webcam Farsightedness

[Vik Oliver] came up with
a webcam focus fix
that is so quick and simple we never would have thought of it. He received the webcam as a gift and mounted on an articulated lamp so that it could easily be positioned around his projects. The problem is the camera lacks a focus adjustment so the close-up shots were blurry.
In what we consider a
eureka moment
, he sourced a pair of dollar store reading glasses to fix the optics. The glasses came with their own mounting bracket. He clipped them in half and wrapped the wire ear support around the camera body. Great hacks
don’t have to be complicated
, and we need to do a better job of looking at the
dollar store for project parts
!

I removed the “lamp guts”, disassembled the webcam and the tap light, strung the USB cable through the neck of the lamp* and mounted the tap light and webcam where the lamp’s reflector used to be.The exposed lens assembly allows me to adjust focus easily, and the light keeps the scenes from the relatively poor-quality camera brightly lit.* this is trickier than you might think. The cable was just barely small enough to fit in the center of the gooseneck, and the plug at the end was no help… Think this step through carefully.",

Build Your Own Lightweight Flash Tripod

[
"digital cameras hacks"
] |
[
"flash",
"poles",
"tent",
"tripod"
] |
[Peter Karlsson] is a commercial photographer who wanted some ultralight, portable supports for multiple flashes.
What he came up with
meets those goals; measuring 16 inches long when folded and weighing just 14 ounces. They set up just like a tent because they’re made from tent poles. Like the portable habitats, the tripods have bungee cords running through each section which holds them rigid but allows them to fold for transport. This is a great sister project to
the flash synchronizer
from yesterday. See the demo and the
building instructions
after the break.

IPhone Case Rehabilitation

[
"iphone hacks"

[
"3m",
"case",
"iphone",
"rehabilitation",
"restoration"
] |
[Richard Cabrera’s] iPhone was scratched from years of use. A big part of the appeal of Apple products is the dose of sexy that comes with them, so he set out to remedy this abomination. His
iPhone case rehabilitation
guide walks you through the miraculous transformation. One of the tools he uses is a headlight lens restoration kit from 3M because its polishing pads include graduated levels of grit for the transition from rough sanding to buffing. As you can see, the logo and text have been buffed off but that’s a small price to pay for what looks like a shiny new device.

[H. P. Friedrichs], the creator of the
Static Bleeder
has created his own
diodes
. Using household chemicals, a film of
cuprous oxide
was made on a copper pipe cap. Cuprous oxide has been one of the first known semiconductor substances, has a low forward drop but is an otherwise asymmetrical conductor, odd V-I curves, and some neat photovoltaic action. The apparatus seen above is used to bring a piece of lead (in this case, solder) into contact with the salmon-colored cuprous oxide while electrical connections can be made to the binding posts at the front. What are your thoughts on this device?

I did a quick search and turned up the following.Copper oxide has a knee of 0.2V, but the reverse breakdown voltage is around 5 Volts, so for many applications a series of diodes is used to increase the reverse breakdown (and as a side effect the knee voltage will be higher). The other drawbacks are metallic rectifiers are affected by temperature, atmospheric conditions (I guess could be fixed by different construction), and aging (e.g. resistance goes up over time).Some basic information:http://en.wikipedia.org/wiki/Metal_rectifierandhttp://www.tpub.com/content/neets/14179/css/14179_38.htmAn in-depth article of properties:http://answers.google.com/answers/threadview/id/397640.html",

A transistor isn’t just two diodes – it is a sandwich of two pieces of bread with some semiconductor meat between them e.g. NPN has P-type semiconductor meat. When you put a voltage onto one PN junction it starts conducting and that changes the electrical properties of the P so that the other junction conducts too. That doesn’t happen with two open meat sandwiches (two diodes) with wire between the meat.I am trying to think of a good car analogy using a freeway, an on-ramp, and an off-ramp with a road jam and charge carrier cars…",

[Michael] sent us a link to his
RC robotic platform
. He started with the same RC toy as the
iPhone Robot (CAR)
but ended up with a blank slate waiting for more features. What he has is an Arduino with a motor driver, three bump switches for the front and rear, and a XBee module. On the other side of things he used a SparkFun USB to FTDI connector to interface another XBee module with a PC in order to use
Processing
.
In the clip after the break you can see the motor control needs to have more fine-tuning done so the beast isn’t just out of control when running. But there’s a ton of potential here. It should not be a problem to add at lease rudimentary video feedback from the device. The Arduino is currently only being used marginally, leaving plenty of space to add on-board sensing such as IR, proximity, or light.
It’s a clean start, we expect to see updates!

I know many colleges use (or used) these boards to teach intro to EE/CPE. I was so inspired I bought the blank PCB, then purchased all the components and made my own. It’s got lots (8 or more) ditital I/O, 6 or so analog inputs, motor drivers built in, and an IR link. Interfacing an XBEE shouldn’t be that difficult, but one would most likely have to bit-bang the serial interface (I don’t recall if the 68HC11 has a UART – I doubt it does).",

USB Oscilloscope
|

[
"Tool Hacks"

[
"attiny45",
"c++",
"oscilloscope",
"usb"
] |
Here’s a
USB oscilloscope project
from a few years back. It’s easy to build on a single-sided PCB and very cheap because it uses just a handful of parts. At the center, an ATtiny45 microcontroller uses its ADC capabilities for the two traces and also handles the USB connectivity. The internal oscillator is used and trimmed up for accuracy by referencing the USB clock. On the PC side of things, a program written in C# displays the data coming over the serial bus. Quick, small, and useful; a schematic, board layout, firmware, and PC software sources are all available for download.
[Thanks Shri]

Space Invaders Clock 6 Years Ahead Of Pong Clock
|

[
"clock hacks"

[
"adafruit",
"ks0108",
"pong",
"space invaders"
] |
Space Invaders came out in 1978, six years after Pong. That means
this Space Invaders clock
uses newer technology, right? Nope, it’s the same hardware as
the Adafruit Pong Clock
with some updated firmware. Still, as you can see after the break, the effect is pretty nice. Pong was cool, but having a clock that scrolls through several classic games would be cooler.
[Dataman], the guy responsible for this firmware hack
shared his code
. It should be easy enough to alter it for
any clock using a KS0108 graphic LCD screen
. So what’s next? Can someone pull off a black and white
Ms. Pac-Man
that looks decent on the 128×64 display?

A VU Meter For Your PSP

"psp",
"VU meter"
] |
[Christian Doran] wanted some blinky goodness to go along with the tunes on his PSP. He
built a VU meter circuit
around a couple of LM324 op-amp chips and fit it into the UMD space on the back of the PSP. Using surface mount LEDs and some fine wire he lined up a string of indicator lights round the circle on the clear UMD cover. As you can see in the video after the break, the back of the case now pulses along with the music.
[Christian] notes that
building the VU circuit around an LM3915
would have been much easier but he’s working with what he has on hand. Looks like he achieve the effect he was after. If you want to learn a bit more about
how the op-amps work
, take a look at the tutorial from our links post.

Meet GåågleBot.
GåågleBot is a modified
roomba
that will not only vacuum your home, but collect data while it does it. While it is carrying out its normal duties as a floor cleaner, it will take pictures, collecting and analyzing all the data for later searches. With built in OCR, you can actually search for things using text strings.
Aside from just carrying out its normal job, you can also remote control it via the web. You can even control theirs!

Is GEK A Modern-day Mr. Fusion?

[Nanomonkey] spent the weekend building generators that run off of syngas.
All Powers Lab produces Gasifier Experimenter Kits
to convert raw material to energy. The kits use
Gasification
to make a “
natural gas like
” fuel from materials such as wood chips, walnut shells, construction debris or agricultural waste.
So is this the
Mr. Fusion
that powered the DeLorean?
This Honda fitted with a GEK
sure makes it look that way. But all joking aside, this looks like a great way to turn waste in heat or electricity. There’s tons of info on the site to dig through. The controllers are open source which would make it easier to interface with the
Google PowerMeter
when the system is used as a generator.

It’s very important that the gas be clean before feeding it to your IC.@HIrudinea making the syngas at home is a possibility, although cracking the tars is achieved much more efficiently if you can use some of the waste heat from your IC. Also, compressing gas consumes energy. Most of these units are meant for home power in rural areas where there is no grid. Or people in the case of the Shipyard (www.theshipyard.org), had their power turned off by the city for more political reasons.@PocketBrain what is convenient is taking a cross country trip and never having to stop for gas, only stopping to pick up organic matter left along the side of the road.

Needing a front fan to keep his hard drive cool, [CalcProgrammer1] found he was unhappy with a single LED color for the fan. He swapped them out for a set of four RGB LEDs and
whipped up his own controller board
for the unit. It is based around an ATmega168 and patches into the COM2 header on the motherboard, providing a serial interface. [CalcProgrammer1] wrote a GUI to control fan speed, and individual LED color settings. You can take a look at and enthralling, edge-of-your-seat demonstration of how slider controls work after the break. Wouldn’t it be great if the
HDD LED clock
could be adapted to use a fan so that the front panel had a colorful analog dial on it?

Vacuum Pick And Place For SMD Parts

[
"smd",
"vacuum"
] |
[Pete] has written up this in depth how-to on building a vacuum pick and place from an
aquarium pump
and a pen
. The pump conversion to vacuum is extremely simple, with a slight modification to a valve being all that is necessary. The pen is only slightly more involved, but still extremely simple. This entire project could be done in an evening for less than $30. If you’re doing a ton of SMD work, it could be a no-brainer.

Automatic Telephone Recorder

"telephone",

] |
[James Bond] types and those suffering from a hefty dose of paranoia can now record all telephone conversations. [Trax] built
this module that monitors the phone line and starts recording
when a handset is picked up. A computer does the actual recording, triggered by the microcontroller via a USB connection.
We like the use of an old PCB for a faceplate, we’ve certainly got some duds of our own sitting around. The three cords are a bit confusing though. One for the phone line, one for the USB, but what does the third do? Is it an audio-out connection?
We’ve asked [Trax] to post a schematic and source code if possible so that might clear up the mystery.
Update:
[Trax] let us know that there is a red button with white lettering at the bottom labeled “download”. This contains schematic, code, pcb layout, and PC software. We just missed it the first time around.

FanWing Is Like A Harvester In The Sky

The
FanWing aircraft concept
has been around for a while but this is the first time we’ve seen working models. It gets rid of the propeller and adopts a rotating cylinder for propulsion. The look reminds us of a
combine harvester
and in a way it does reap the air, pulling the craft through the sky. We’re not holding our breath for the decommission of jet propulsion in the wake of this method, but we’d love to see some
fun-loving death from above
whenever you can get your own off the ground. Check out the video clips after the break to see, and hear, this in action.

I mean the first video showed one with what I assume is a fan made of balsa wood so perhaps one only needs to find the proper ratio of number of fan blades, blade angle, and fan diameter along as well as fan speed to move the proper amount of air without causing undue stress on the components. So maybe it’s better to have more/smaller fan blades than only a few larger ones.I say this because I’ve got a plastic paint mixer that has the same type of design and the plastic is strong enough to work under a load that would be comparable to moving an aircraft with a heavy load. So it seems using modern materials might give better benefit.The gyroscopic effect would increase the stability enough that it would make it a great design for personal/experimental aircraft.",

That’s got the potential to give more lift at the expense of losing some protection against negative ‘G’.Under hover conditions the tip-bearings don’t need to touch anything, you can control rise and fall with rotational speed.Something like that ought to be relatively simple to synchronise for a multi-rotor machine too?Can anybody push that idea further?",

Hacking Space Without Profit Or Secrecy

Reader [Jacob] tipped us off about a
project the aims to make the final frontier open source
. The
mission
of the Copenhagen Suborbitals is to launch a man into space. What they’re not interested in is turning a profit, carrying
hazmat
or weapons, or keeping what they learn to themselves.
Surprisingly enough, isn’t this the next logical step after
hobbyists send cameras into space
? This team thinks so and they’ve been hard at work building and testing rockets. With the last round of successful tests behind them, they’ve paved the way for a launch of the first round of
the campaign
on June first.

Smart Flash Synchronization
|
Mike Szczys

[
"digital cameras hacks"
] |
[
"arduino",
"flash",
"nikon",
"trigger"
] |
[Max] designed this
circuit to add smart flash synchronization
to his photography arsenal. He did this because ‘dumb’ TTL based flashes won’t play nicely with more sophisticated systems like the
Nikon Advanced Wireless Lighting
. By building a microcontroller into the mechanism, he’s added functionality for several different scenarios, ensuring that he’ll never again have problems with early flash triggering. Now that the kinks have been ironed out in the prototype, the code and hardware can be migrated over to whatever microcontroller suits you.

Portable Squeezebox With Serial

The Squeezbox media streaming systems are compact Linux WiFi enabled radios that let you stream your collection anywhere,so long as you have an AC or USB outlet nearby. But [Achim Sack] wanted to stream his collection from anywhere
with no wires attached
(
translation
). Some poking and prodding revealed a connector actually designed for a battery and serial, but no commercially available battery yet.
The system requires a temperature sensor and if you want serial,
a USB converter
, but overall a simple process that could be done in an afternoon. Giving your box ~10 hour of life and even fits inside of a back compartment.

112-LED Coffee Table
|

[
"LED Hacks"
] |
[
"atmega328",
"coffee table",
"matrix",
"tlc5940"
] |
[Joe] tipped us off about his
112 LED coffee table
. This 12-ups
the LED matrix
from Friday and 31-ups the
Shiftbrite table
. Driving
this grid
is an ATmega328 in i2c slave mode. It listens for display data from a second ATmega328 and uses that to set the array of
TLC5940
driven LEDs appropriately. Separating the processing microcontroller from the display microcontroller allows for fast and smooth display changes that can be seen after the break. [Joe’s] table exhibits exquisite cable management, clean code, and an amazing amount of flexibility. Maybe [
Caleb Kraft
] will finally pony up the dough and make this project for his own home.
[Joe] waited until he saw some other LED tables to send us a link to his hack. This is obviously an awesome project, one that we want to see just as much as our readers do. So please, don’t wait for someone else to stumble upon your project,
send us a tip
once you’re done
sharing the details
.

We always wondered what happens to ancient pianos when the internals can no longer be kept in a playable condition. [Jean Philippe Roch]
gutted his elderly upright and fit a Korg Triton inside
. After the break you can watch a few videos including a slide show of the work log. [Jean] separates the Korg keyboard from its case and places it in the empty upright piano rank. He then mounts the Korg’s controls in the front panel and adds motorized control to reveal this hidden secret. The project is finished with speakers in the bottom portion of the upright and blue LED lighting effects.
The result is a pretty nice show-piece. It’s not as hacky as
vocoding
, but we really love the finished look.

Fix 0LBA And BSY HDD Errors

One of the worst moments almost every hacker has experienced is a hard drive inexplicably dieing. And of course, its at the most inopportune time and you’ve had no chance to backup!
Recently there has been an influx of Seagate hard drives (specifically the 2700.11s) kicking the bucket with firmware errors
0LBA
and
BSY
. The good news is [Gradius2] has made guides to unbrick your drive without having to match serials.
The procedure is lengthy, complicated, can easily become expensive, and there is the possibility of losing your data so it’s not recommended if you’re only getting those pictures of Mr.Fluffykins back. In such a case,
Thermite
might be a bit better solution.
[Thanks Calvin]

I seriously considered the DIY fix (which is by no means new, I don’t see why this deserves a posting here), but I decided to see what Seagate is doing about all of this.Five days ago I called Seagate support (go to warranty extension on the phone). Email support was incredibly useless, they gave me a link to the firmware update and closed the case –and a second time after I reopened it. Anyway, I had a short talk with the warranty guy, let him know I know what I’m talking about, and he confirmed the drive had the firmware problem. He transferred me to the technical line where the problem was once again confirmed and I was given the phone number to i365, the Seagate data recovery people.Slightly confusing here, just dial 0 for “other”. Give them your case number, they’ll give you a website to apply to to have it sent in.They pay $5 for packaging at UPS Stores, it’s free shipping OVERNIGHT to one of their facilities and they let you know when it comes in and how the job went. They send it back UPS ground. It’s coming Tuesday, all my partitions restored, no risk involved (on my end). I can assume their process is very similar to the DIY method, and while it’s nice to know I could have done it myself easily enough, I didn’t have all the necessary hardware on hand and this just seems easier.The only thing is that they do a sector-by-sector imaging of the disk and keep it for 14 days (then to be overwritten), which I’m not a fan of but I’m sure it’s just standard procedure. Just unnecessary.",

[Anders] tipped us off about his hack that
re-purposes a smoke alarm as a burglar alarm
. Unfortunately, he came home in the middle of a burglary but wanted to be ready the next time someone tries to break in. By cleverly patching into the test button on an old smoke detector he created a circuit-trip alarm. One side of each piece of wire is secured to the frame and jam of a window. A paper clip completes the circuit by pinching the two bare conductors. If the window is opened the connection is lost and the alarm sounds.
We see a few problems with this system. First off,
never hack your ONLY smoke detector, you are putting lives at risk by doing so
. But [Anders] says he’ll have a replacement detector and since these things need to be replace every ten years or so, chances are you can find an old one kicking around. We’d recommend disguising the case so that people aren’t confused about it being a smoke detector. Secondly, he’s mounted the alarm right in the window frame so most likely an invader will just smash the thing to bits.
Anyway, it’s still an interesting reuse of these ubiquitous, and life-saving, devices.

I’m at home during the day, specifically to guard the house from outsiders, so I’d rather have a simple siren that alerts me to arm myself. This smoke alarm thing is a great idea, and I’m actually surprised “how to make a burglar alarm from a smoke alarm” turned up any search results. That said, I do agree, you should position this alarm much more securely. Otherwise, this seems like a lovely way to reuse scraps for home security.",

Two Input Devices Made With Common Items

Here’s two input devices you can easily build with materials you already have on hand.
To the left, [John] built a 3×3
keypad matrix from paper and tinfoil
. The rows and columns are made up of strips of tin foil on the front and back layers of paper. The layers are separated by spongy double-stick tape. A ‘keypress’ results when the gap between the conductors is compressed with your finger.
In much the same way, [Dave Fletcher]
built a touch potentiometer
. He made two resistance plates by scribbling pencil lead on sheets of paper. When the two plates face each other, separated by the same type of foam tape as before, they can be pressed together to form a circuit with a variable resistance. This results in a crude version of the
SparkFun softpot
.

The biggest problem is the Al foil–if you look at the stress-strain curves, when you press your finger that far into the foil, you definitely exceed the region where it’s elastic. In other words, you permanently deform the foil (i.e. it wrinkles up) and you eventually get a permanently on button. If you could make the separator thinner (and more resilient to compression) and increase the conductor size somewhat (or better yet, use spring steel or similar), it’d work better.Great for prototyping, though!",

When it comes to routers, there is one that is hacker’s favorite, the WRT54GL. But a slightly lesser known company, Pirelli with their “Alice Gate2 plus Wi-Fi”, seems to be a popular choice among our Italian friends.
[Esteban] has done everything from installing
serial and parallel ports
, to
unlocking firmware
while installing
Debian
. Our personal favorite is the creative wiring of an
additional USB port
, where he had to custom create a power circuit to run his webcam and external drive.
[Thanks Marco]
[Update: It would appear Roleo, Beghiaro, and Zibri did the actual grunt work at
ilpuntotecnicoeadsl
and Esteban simply wrote the guides. Thanks for your hard work and hacking skills guys!]

Yet Another Pong-clock

"pong clock"

[PT] let us know that
Adafruit Industries has just release a pong clock kit
. The $80 price tag might seem a bit steep but it does come with a custom-ordered KS0108 display in order to get white on black like the classic video game, as seen after the break. Also included is the laser-cut case, an ATmega328 microcontroller, RTC, and all the other bits needed to get this working.
We just saw a
pong clock built on a breadboard
using a KS0108 display but that one used a PIC processor.
Adafruit
always open-sources their designs and code so you can head over to the
kit details page
if you already have the hardware on hand to throw this together.

Ordered in December, and promptly shipped and received. You must not be trying very hard to get one. Or maybe you just like to whine”.as you can also see, the commenters seems to be saying that instead of posting “unsavoury comments” on hack-a-day and saying we’re a “joke” you could have just emailed us directly and we’ll help you out immediately.now that you have emailed us (we’re replying in less than 20 minutes from your email) we’ve checked the icetube clock back order list – you’re not on it at all, we know this because we’ve shipped out every order. if you were sent a notification it went to spam or just didn’t make it. if you’re just checking the page manually, you’ll often see them going in and out of stock. that’s not the best way to know, just sign up or email us directly.as the x0xb0x goes, if you did indeed sign up in june of 2009 you’re on the list – we’re not up to june 2009 yet. so this is why you do not have a x0xb0x yet.-adafruit",

Steampunk Sequencer

"steampunk"

[Moritz Wolpert] built this gem of Victorian hardware by hand. It is a sequencer and features beautiful detail work as shown in
its MySpace gallery
. Other than that we don’t know a lot about it. You can also take a look at
[Moritz’s] main page
, but prepare to be annoyed by the hideous web-styling that really undercuts the beauty of his physical product.

Hacker Finds Better Use For A Windows Machine

"aquarium",
"betta",
"fish",
"glass block"
] |
[Patrick Becker] had an ancient PC on his hands with a blown PSU. He converted this into
a stylish home for his
Betta splendens
.
The aquarium itself is fashioned from a piece for construction glass block with the top cut off. This allows for a window that looks through the tank and shows off the motherboard on the other side. He patched into the AC connector so that the original power cord can be used to control the pump. A lighted pump button was added to the front panel and a fancy bezel fitted to the viewing portal in the side of the case. He finished off the project with a PVC pipe for air and food. His blue screen of death now features water and a real fish.

Did somebody at HaD assume that all dead computers are Windows? Did they think that PC == Windows? Is this just petty OS bashing?As a side note, I’m sick of the OS bashing, as I’m sure everyone else above grade four is. Windows is fine. So are Mac OSes and Linux distros. Choose what makes you happy, and don’t try to start stupid fights on the internet.also,@BigBubbaXSeriously? If you hate Windows, why not wipe it and replace it with Linux or make a Hackintosh? The only solution you can think of is technological evisceration? Are you some sort of technophobe?…I think I just broke my “no stupid fights” proposal…and in the same post, too…",

DoomBox: Classic Keys Meet Tiny Screen

"doom",

The
doomBox is a dedicated gaming rig
for lovers of ID Software’s classic title. [JJ] built this from an old Kodak DC290 camera that had a broken lens. Since this runs the
Digita OS
, he was able to use the Doom port that already exists. But the camera’s factory buttons were not well suited as controls. By whipping up his own button board, and using the traditional keyboard keys for the button caps, he achieved a much more comfortable (yet squint-inducing) gaming experience. The finished project resides in an all-too-familiar black project box. See him fire it up after the break.
The original Doom for Digita OS pages seem to be down so
here’s an alternate
if you’re interested.
Update:
Looks like
the original website is back up
.

Phone/webapp Written In Ploy To Appear More Popular

"Cellphone Hacks"

[
"cell phone",
"tornado",
"twilio"
] |
That title’s not really fair to [Evan], but he did write a
cellphone tetris game that causes your handset to automatically telephone him
if you win. He’s using two applications that we’re not very familiar with,
Twilio
and
Tornado
. The former handles control input from the cellphone via their simple API. The latter is a web server and web framework that runs the actual game.
If you’re interested in how he put the two together you can
poke around in the code
. If you really don’t care about how it is done, you might just want to win
the game
, automatically giving [Evan] a call, running up his wireless bill in the process.
Help us add some value to this article by leaving a comment. We’d like to know how Twilio compares to Google Voice which doesn’t seem to have a published API (but there is
some work in that area
). We also think web-based cell phone interactivity, already
popular in hacks
, is just beginning to build some steam. What are the tools you use to make cellphone interfaces easier and quicker to implement?

I’m waiting for my refund check as the result of a large class-action suit on the matter.While I’m on this rant (and of topic, sorry), this reminds me of years ago when I had a land-line. They wanted to CHARGE me to block long distance calling. That’s like going to McDonalds and paying a penalty for not buying fries with your hamburger.",

SparkFun’s
BatchPCB
has been a well-known service to get your PCBs fabbed, and now it is sporting a new feature. It has just come out of its downtime chrysalis with the ability to pay you for making your designs. If you have designed a PCB and want people to pay you to use it, BatchPCB will now do that for you. [Patrick] says “We want engineers to benefit from the low-cost production for prototypes and have the ability to sell their work, conveniently.” There are a few caveats. First of all, each seller must be a resident of the United States and send BatchPCB a W-9. Secondly, PCBs are only warranted against manufacturing defects, so buyers should make sure the PCB they are buying is a working design. Finally, the sellers must only be selling designs of their own or with proper permission. We are big fans of free, open-source designs, but we can see how this would help an engineer recover some of their costs to develop a board and might lead to some interesting brokering of designs. What do you think of this new service?

And nobody makes anyone buy from them. They surely don’t have the volume and overhead of Digikey, and can’t offer the same prices. But if people are buying, and they seem to be, then they must be willing to pay what is asked, for whatever reasons. It cannot be gouging if there are alternatives, and to say so is silly.Getting all bitter and chestbumpy misses the point. A thousand flowers can bloom in a free market.

But, even if BatchPCB is overpriced, another company could take this same idea, and it would probably be a useful service.hmm. In fact, a short-run kit-fulfillment site could be a neat business.designers upload a schematic and a parts list, and set a markup %.users browse lots of kits, and purchase one.the site charges for the fab & kit, plus markups for the designer and site.users get their kit, with professionally etched PCB and all necessary parts.It could be a nice middle-ground for designers.

I’ll take into consideration what I already knew about their prices not being the greatest, but like I said, I already figured that out. Nothing against them, I realize its just the level of business their on.

Biped Walks With Eight Servos

This tiny biped
shows a lot of coordination in its movements. As you can see, eight servo motors account for the locomotion with an ATmega8 as the brains of the operation. Posts for the
first
and
second
generation of this little guy feature several videos. We gather that a spreadsheet is being used to tweak the preprogrammed movement sequences. Trial and error, that’s how humans learned to walk, right?

Open Source Logic Analyzer
|
Mike Szczys
|
[
"Tool Hacks"
] |
[
"logic analyzer",
"OpenBench Logic Sniffer"
] |
Hackaday alum [Ian Lesnet] has been working in cahoots with a dedicated team of developers to produce the
OpenBench Logic Sniffer
. This caseless logic analyzer can operate at 100MHz and sample 32 channels at once. Better yet, a
digital oscilloscope add-on
is in the works. The
pre-order
comes in at $45, that’s a lot of functionality for just a few greenbacks. We’ve embedded a demo video after the break that details installing and using this device under Ubuntu.

It’s also open source so anything you don’t like can be changed.The command line is only required in Linux.:) The windows download has an included JRE and all that needs to be done is double click on an executable.The video is just a demo to show that the client works under linux. I personally run it in Windows when I’m debugging something. The UI is not buggy, rather I made a silly mistake by recording a screencast at such a low, 800×600, resolution to make it easier to view in embedded webpages. The main window is resizable but the window that I had opened to set the capture options was a child window that was not resizable. On displays 1024×768 and larger the child window easily fits but in 800×600 it was too big. I don’t think many people run 800×600 any more so it has probably never been considered a bug. Anyway, it is open source so it is easily fixed.Probes are not included, Ian is working with Seeed Studio to make the probes available for purchase.No soldering skills are required, $45 is for an assembled board.Jack GassettGadget Factory",

Lower Productivity By Using A Rotary Num Pad

[vimeo=http://vimeo.com/9618204]
[Maximilian Ernestus] sent us a quick little demo that shows him using
a rotary phone dial as a num pad
. We’re often frustrated when notebooks and netbooks prohibit us from using our mad 10-key skills (alternate key mapping doesn’t count). This makes coding and using
GnuCash
undesirable on small form factor portables.
Instead of fixing the problem, [Maximilian] made it worse by interfacing a rotary phone as a num pad. An Arduino counts the pulses and feeds them to the computer via a serial connection. From there it’s just a bit of software handling to issue a keypress. He mentions that a future version should register as a USB keyboard. This is a great opportunity to ditch the Arduino and use the
V-USB library
.
Want to dig a bit deeper into this old technology? Don’t miss out on the information available from the
Magic Phone hack

10×10 LED Matrix

[KopfKopfKopfAffe] just finished a 3-year labor of love resulting in this
10 by 10 LED Matrix
. This trumps the
Shiftbrite table
from earlier today by bringing an actual 100 LEDs to the display. These LEDs cost much less than the Shiftbrites, but since they don’t have their own on-board controller this project requires much more back end work. A total of 25 ATmega8 microcontrollers drive this display, in turn controlled via an RS-232 connection to a computer.
We love the
Lemmings
animations. It made us realize that this would be a great candidate to play
Super Pixel Bros
on. Check out the video after the break for snapshots of the hardware as well as videos of the matrix at play. You may also want to peruse the
translated work log

I once build a 16 RGB Led array with 8-bit color depth and 200Hz refresh rate. This all with one ATMega644 at 16MHz and some shift registers. I don’t know if you could make a 100 Led matrix this way, but you might get close. A nice trick I used for the PWM was Bitcode Manipulation (http://www.batsocks.co.uk/readme/art_bcm_1.htm).But in the end the easiest thing to do might be taking a LPC17xx ARM processor running at 100MHz.

If you’ve ever been caught in the situation of needing to drill a clean straight hole down the center of a bolt or rod, you’ve probably tried and ended up with a broken bit or tilted hole, and a ton of cursing to boot.
[Vik] let us know about this
nifty trick
for drilling ‘down the middle’ using a simple
hobby drill press
and vice. He claims it’s ‘physics guiding the bit’ but in reality its just crafty use of a chuck. Either way the quick trick works, and will hopefully save a lot of hackers some headaches in the future.
Let us know in the comments if you have any simple quick tips that you use when you’re out in the shop.

"content": "5 years late, but oh well. At first glance I thought they were the same, but it’s actually not the same at all. They are in fact exact opposites.With the bit rotating, the tip of the drill bit is always central to the rotation, and central to the hole it’s drilling (not the piece the hole is being drilled in, obviously, but the hole itself). This does nothing to center the hole, but it does drill a very nice, perfectly straight hole, which is the point of drill bits.With the work rotating and the bit stationary this relationship is flipped, and this causes the cut of the drill bit to always seek the center of the work, rather than the hole it’s cutting. This is the whole point of lathes, and why you can do perfectly symmetrical work on a lathe. Seriously, watch normal lathe work with someone working on the end rather than the side. It doesn’t matter how far away from center he starts, all the guy with the blade has to do is move sort of toward the middle and it automatically works in to dead center. I don’t mean close to center, I mean perfectly centered on the rotation.What this means is as long as your bit is reasonably close to center, you will always drill a perfectly centered hole. If it’s NOT reasonably close to center. it will jam up and possibly break the bit and ruin whatever you’re working with, depending on how strong all of your equipment is.",

"content": "I have a couple criticism of the article:First, hand sharpened drill bits do not drill straight. They chatter. The holes they make will be out of round and off center. Sharpening the flutes symmetrically and with proper angles requires specializes jigs or highly configurable grinders like the beauty recently featured on Hack A Day. I’m not suggesting throwing out your bits, but keep one set of properly sharpened bits for jobs like this.Second, even a bit that is sharp and true will tend to wander than starting a hole. Machinists who need accuracy start their holes with either spotting drills or center drills. TFA’s approach might work most of the time, but if you want to get it right every time, put the work piece in the vice and use the correct tools.I’ve become something of an evangelist for hobby size machine tools. A table top lathe makes this chore a breeze (tighten stock in 3-jaw chuck, drill), and opens up a world of possibilities. I waited until well into my 40’s to get some really cool tools, and regret not starting out 30 years earlier.",

It’s how people drill gun barrels, for instance, since the drill is self-centering when used this way so it’ll run right down the middle of the stock. It is also a good technique if you need to put a centered point on the end of a rod: chuck it in the drill and spin it against a bench grinder. You’ll get a nice sharp well-centered point.

Rotate the work, not the drill, as we’ve already said. Amazon.com will sell you really long thin drills, like 1/8″ drills 12 inches long, but I’ve found they don’t really work well because the flutes make the drill squirm and cut poorly. Use aircraft drills, that have long unfluted shanks with only a short fluted section at the very end. Peck: drill in maybe twice the diameter of the drill, then pull it all the way out to empty the chips. And if you can manage it, double-drill using one drill about 1/8″ or so smaller than the final size, and the second drill the final size, drilling an inch in with the smaller drill then following up with the larger, alternating as you drill through. (Similar to cutting a long thin rod on a lathe.)",

swapped out his twin-tube florescent aquarium lights for LEDs
. By running tank water through the aluminum LED mounts he’s transferring excess heat into the water in the tank, in turn saving some of the electricity that would have been used to heat the tank. Couple this with roughly 35 Watts saved by moving away from fluorescent tubes and he’s got a great energy-saving hack. The LEDs used in
the last aquarium light conversion
were cooled by heat sinks and fans. We’d love to see this concept incorporated into that design.

Nokia USB Cable Is USB-to-Serial In Disguise

[Jethomson] worked out a way to
use a Nokia USB cable at a USB to Serial cable
. He was able to pick up one of these cables for less than $3 delivered. A little probing worked out which conductors go with the appropriate signals and from there he developed a way to protect the 3.3v signal levels with a voltage divider.
It’s not surprising that this works, having seen [Will O’Brien’s]
post covering serial communications on Nokia phones
. In that post we learned that the Nokia phones are using TTL communications. Once you’ve completed [Jethomson’s] modifications to the cable you can follow his examples for using this in conjunction with an Arduino.

Nowhere in the article do I say anything dumb like USB-to-FTDI. The poster came up with that title. I may call it USB to TTL, but that’s not strictly correct. It is a USB to Serial with 3.3V levels but works with 5V signaling. It doesn’t do everything an FTDI cable can , but if all you need is RxD and TxD (and DTR if you work for it) then this cable is good enough.@fdsa, Maybe you don’t mind paying $20 for an FTDI cable, but I’m sure others would like to save a few bucks.@Pete, That’s a good price. A BUB board from Modern Device is even cheaper. But I think you’ll agree if you want to leave the cable permanently attached to your project $3 is better.",

Bad hackaday!For those less knowledgeable, the 3.3v FTDI TTL asynchronous serial and multi-mode chips are 5v input tolerant (at least for every chip that I used). 3.3v is also above the “1” level for 5v TTL logic, so using a 3.3v TTL FTDI chip to talk to a 5v part is OK! I abuse a FTDI 3.3v breakout cable like this at least once a week on random parts and have never had a problem. jthomson’s hack by adding a voltage divider to 5v intolerant parts is a classic technique, and one that works quite well.I’m a big fan of FTDI chips because of the functionality and reliability. That said, simple USB based serial connections are best with a PL-2303. They’re quite effective, well supported, and dirt cheap.",

Python IR Tracking For The Handicapped

"tracking"
] |
[Techb] had a friend who was paralyzed after an accident and could no long use a computer. He rigged up an amazingly
simple mouse interface using python to implement infrared tracking
. The controller was built from an old hat by adding an IR LED and wireless mouse modified so that the button could be clicked by the user’s mouth. A
webcam with exposed film used as a filter
can track the IR LED and take input from the wireless mouse buttons.
This setup, which draws inspiration from
Wii Remote white boards
, is much simpler than
the Eyewriter
(and doesn’t shine an IR LED into your eye). Although [Techb] wants to add facial recognition to the system, there’s something to be said for such a simple implementation.

He was just fucking around, and ran into a handicap guy that was complaining, and realized what he had been fucking around with could help the guy.Still a nice thing to do, but it doesn’t sound like they’re even friends after the fact. Just some guy he felt like helping… I guess that makes it even better, but whatever. My favorite line was “no he gets online and looks at porn just like the rest of us!”@UKSci: atrain is right. It filters everything BUT IR. It is powered by a python script after all; It’s just looking for the colored dot I would guess. Sounds like eventually he wants to do facial recognition so he won’t need the hardware hack.",

It looks for the first true pixel value from the getprojection() function in PIL.I have written a new updated version that looks for the highest RBG value to base on. It can read two IR dots now. Mouse movement isn’t incorporated in the new version, but could be implemented via slop degrees.My ultimate goal was to mimic the WII with my webcam, it just happened to help someone in the process.",

The fact that he took time to come up with this is awsome! It takes some one who cares with the know how to do this!So while those of you are wondering “which term” to use, Tech B will be helping those that need it! I am for one very proud of Tech B!",
