Made from a 1200 dpi epson scanner and a manual focus canon lens,
this camera captures 130 Megapixel images
. With a resolution of 13,068 x 10,173, these pictures are very detialed. You can see some examples in his
flickr set
. It doesn’t look like they’re the full size originals though. If you want to build your own,
here’s a good start
. Keep in mind that it’s from 2004 though.

Huge stationery buildings all around, and maybe a few cross-streets with heavy traffic. It seems to me all the stationery objects would show up as expected, but the stream of moving objects I could only imagine would show up as a stream of mis-matched patches in strips perpendicular to the direction of travel.I would love to toy around with a device like this, I’m sure you could produce some pretty interesting artistic type shots.",

[Mike] was going to be biking across Canada.
He really wanted to document the trip
, so he began planning ways to get still images taken at intervals along the way. After a bit of brainstorming, he ended up setting his goals a bit higher. He was going to film the entire trip. He really didn’t want a simple helmet cam, he wanted himself and the entire bike in the frame. To do this he had to
build a long arm on which he mounted a bullet cam
. On his handlebars, he has a simple control where he can turn the system on and off as well as initiate recording.
No single piece of this project was too complicated, but taken all together, the final result is quite nice. You can watch the video for yourself after the break.

He said it made him feel good about life again. Please know, acknowledge and appreciate that you, and what you did, has changed someone’s life, all be it a little, in a positive way.I feel for your struggles all the way through. The stomach pains, the flat tires, the helmet hair-do, the climbs, the weather… but most of all documenting it all. Great technical achievement with the side cam (construction), the editing, music, the titles, and shooting (various angles and shots), and scenery. Very well made. Doing the trip is hard enough, but documenting it, man that is tough! Oh, by the way, people who haven’t done a trip like this won’t ever get it or appreciate it.Nice to see other riders – with dogs! I love the down hill rides, I know you do too. So few people, it must have been very introspective, as well as good exercise. Did you pick up any chicks? What was your top speed? Did you ever forget to unclip you pedals? Nice to get a bit of radio too.For most people there needs to be a destination and a purpose, but its not essential. Some find the purpose as they go along or when they finish. Others never quite finish. Either way, its amazing what the human body can achieve with the right spirit. With all that you achieved, with all the people that you have reached, why not add a deeper message? peace? ecology?I never saw a bear during my 11000 km trip around japan, but I wore yellow for some other symbolic reason and hit lots of hills too. Check out my trip onhttp://www.flickr.com/photos/1manjapan/tags/1manjapan/(you start at the end of the trip so jump to page 40 if you want to see the beginning). See you on the road one day.

If one thing comes up by cycling it is that the mind is totally free, because the body moves automaticly.Due to cycling (or any other thing one does automaticly, even washing the dishes) the mind often comes to ideas and thoughts, that would not appear sitting in an easy chair next to the fire.

Pleo Gets Another Chance

[Robert] sent us some
news on Pleo’s future
. Apparently a company called Jetta has bought the rights to Pleo during the
bankruptcy
sale. They intend on re releasing the cute little robot. They mention that they have built parts for the iRobot line. We wonder what they’ll do, if anything, to make it more appealing.

As many of you have mentioned, there are a lot of projects that are built with their own microprocessors, and are simply overkill. Here’s a reminder that we can do some pretty fun stuff light synchronized light shows without going overboard.
This light show is controlled directly via the printer port on a computer
. Sure you can’t un plug it and run it free standing, but you can build it for roughly $20.

[Asier] pointed us to this video of his
PC-PIC II acting as a peripheral to his EEepc
. You can see him playing pong, using it as a musical input, and even a video game controller. This project seems pretty nice, though we would like some more information. We tried digging around in the “projects” area and couldn’t find anything.

2 Axis Joystick From VCR Parts

[eric] has found that he can build a
pretty nice 2 axis joystick out of some VCR parts
. Specifically, he’s using the idler wheel. When you disassemble the idler wheel, you’ll find that it has a bevelled washer in the perfect location to help with smooth joystick operation. Add a spring and a hole in some wood and you’ve got the basics. All you need to add now are the switches. This is a fantastic example of recycling parts, you never would have guessed that it was made from trash.

[Jacob] wrote us to show off his latest project. He built his
multitouch interface out of an LCD monitor
. We’ve seen plenty of multitouch projects here, but usually they are projection style. This project uses the panel out of an LCD, with the diffusers and backlighting removed. The panel itself is fairly transparent, so a webcam with IR filter can see the light pens right through it. It does seem a bit dim in the video, we’re wondering if it is better in real life.

The newly released
Palm Pre
has been torn down by both
Rapid Repair
and
iFixit
. They note the easy to use interface, but the slide out keyboard makes for weird transitions. There’s nothing surprising on the hardware side except capacitive screen and LCD come as a single unit and would have to be replaced together if either fails.

[Bill2009] has made some nice progress on a
control panel for his motorcycle
over at the arduino.cc forums. It can show speed, tachometer readings for the wheel and engine, as well as indicate the current gear. He reads the square wave coming off of his tachometer input and pulses from a reed switch mounted on the wheel to calculate all this. To top it all off he can monitor the data via a Bluetooth module attached to the board, which is much better than trying to balance a laptop on your knees while cruising down the highway. He is working on getting the size down so that he can mount the whole assembly inside of his motorcycle. He also plans to add new software features like wind resistance calculations and0 to 60mph timing.

You have to read the motorcycle’s handbook for the gear ratios, the LCD’s guide for the display, and the Bluetooth modules documentation for it.

I already have GPS (10Hz – Wintec WBT 300) going to KML, so I integrate the OBD data in the logs so I can replay and test. I have a dashboard app. The n810’s screen is readable in the sunlight though loses color saturation.It is all in the nokia internet tablet talk forums and on maemo.org as minigpsd (it also works under any linux-like OS). I also have a version for my OBD-II as OBD2 in the car and my Valentine V1 radar detector is also linked in. All via bluetooth.(I’m working on reversing the algorithm and tones for the V1 – I already have the display working where it will come to the top for an alert).",

Plus a GPS will give far more accurate speed than the for entertainment only gauges on all motorcycles. Even my 1300GT BMW is off by 7mph at 50mph and it’s the most expensive BMW bike you can buy.Interfacing to the bike is a waste of time, install more accurate sensors instead of the low grade junk the bike makers use and get better data.Plus why BT? why not log it all to a SD card?

I was posting it to amuse arduino drivers and frighten motorcyclists.Some of the code is posted on the arduino forums, as Gerrit says the algorithms for rpm and gear calculation are pretty obvious. It’s a bit tricky to get a balance between responsiveness and precision though. When you look at a speedo or tach you just see a number, and a pretty large one at that. At the pointy end of gear selection you’re counting how many times the engine fires while the wheel goes around once. That’s a small number, anywhere from 4 to 12 so it’s easy to bobble it. You can’t wait a lot more than 1 revolution because each one is moving the bike 2+ meters and in a low gear can be taking seconds.Someone above mentions using a gps and wiimote – the GPS would work fine if you wanted to be able to look down once in a while at highway speed and see what gear you were in – I don’t think it would work well at low speed. The wiimote idea is interesting but I don’t see how you’d pick out a gear change.I’m in deep envy of quan-time who posted the video!http://www.youtube.com/watch?v=FKaJrCT9yP0– but I’m aiming for something rather moree subtle.

The
Camera Axe is an open source system for doing high speed camera triggering
. You know all those pictures people get of balloons popping or drops of water in mid splash? This is how they do it. The system has light sensors and sound sensors to help get the timing just right. It can trigger your camera and the flash to capture images at just the right moment. There are a lot of picture examples on the site as well as a full schematic and parts list. Not too bad for roughly $100.

I really wish someone could get it working on higher end SLR cameras, but to the best of my knowledge nobody has. Even if it did work on SLR cameras it would not be solving the same problem. There is some overlap like timelapse. In general Camera Axe is more about extending your camera with new hardware which allows things to be very quick. Chdk modifies software and for things like motion detection is very slow in comparison. That said I really think chdk is nice software and would highly recommend anyone at all interested in trying it to do so.",

There aren’t many details, or really any at all here. This was just too fun not to post.
Here are two cans strung together
, just like when you were a kid. However, when you talk into one the sound is then converted and transmitted to the other via fiber optic cable. Looking at the pictures, it seems that it is only one way though.

[Jon Stanley] has a nice write up on a
POV propellor clock
powered by a PIC microcontroller. He improved on the original design by [
Bob Blick
]. Jon tried a few different methods of powering the spinning circuit, some of which could be handy for other projects. As a double plus good bonus, schematics and code are all linked on the site. This clock would look nice and sinister sitting on any mad scientist’s dresser.

Reader, [Lennon Luks] made a really slick
MIDI sequencer/controller
for his senior design project while studying at Western Carolina University. It has a grid of 64 LED buttons, 8 knobs, and a display with navigation buttons that allow him to sequence tracks with or without a computer. The controller is based off an ATmega644 and is programmed in C. [Lennon] clearly explains the inner workings of the project in detail on his website and has included a good number of pictures. [Lennon] made a nice video of the project which can be seen after the jump.

We recently posted a story about a
130 Megapixel camera made from a scanner
. We’ve recently discovered a
better view of the internals
. While there aren’t a ton of details. This should be sufficient to get your own hacked together.

[Roland] recently graduated from UC Berkely. For his graduation ceremony, he wanted to do something unique.
He built a diorama on his graduation cap
depicting a house driven from alternative energy. The whole thing is solar powered. The wind turbine is actually powered from the solar panel, and with a remote control, he can make the sun rise and set.

[Raguaviva] shows us in this video how he’s using an
optical mouse as a low quality camera
for his DS. This seems like a pretty cool hack, but we’re at a loss to think of a good use for it. As he gets to the end of the video, he seems to also have trouble thinking of a good use for it. Do you guys have any ideas?

Adapting a different lens arrangement allows the sensor assembly to be suspended above the running surface by a few inches. You can read about it on my website athttp://home.roadrunner.com/~maccody/robotics/croms-1/croms-1.html@LarzI thought about this idea in the past. I called it a “roach eye”. A sufficiently large optical flow, as seen by the sensor, would cause the line that drives the LED to drive more current. The increased current flow could be used to signal an alarm. With a robot, the signal would cause the main robot CPU to access the mouse sensor to read the pixel data. The pixel data could then be compared to a reference data set to determine if a response was needed. Using the mouse sensor for a “roach eye” would require some significant lens design to provide a sufficiently wide-angle field of view. Of course, multiple sensors could be used. This would be like an insect’s compound eye.@laubeWhile the sensor does have a frame rate of 1500 fps, it is not possible to read out the image data at a rate to support that frame rate. The data interface is serial.",

On a hobbyist’s budget not doable unless you have access to a MEMs facility. So a passive arrangement would be preferable. The on board processing would have to be FAST! But with the new processors (32 bit ultra low power) ARM just announced (1mm x 1mm) the processing power is available. I have an old chip bonder so I’d give it a try. And as far as a power source you have to remember it’s only got to be powered up for a few seconds at most for most applications. Maybe a piezo boost pump arrangement rather than a battery so you could keep them in field conditions. You’re going to get a hell of a kick when the bullet is fired. Otherwise for a missile a charged cap so it doesn’t wake up pre-launch and detonate. I’m working on a system to change trajectory of a spinning bullet but it’s far from fruition at this time. Shotgun shell arrangements are the best platform for now because of the size constraints and the fact you can ad retractable wings. Mechanically more complex though. Hell, depending on the IR sensitivity of the sensor you could use it to hit living targets using some sort of signature analysis or hit vehicle engines or whatever. Good old fire and forget technology. You would have to use un-encapsulated parts and be really good at sub-miniature construction. The final cost would be around $5-$10 per round but for a smart bullet that’s cheap. And a shotgun round doesn’t rotate for stability. But nothing beyond the capabilities of some of the people who come here. And you could also produce a device that specifically DOES NOT target living creatures! YAY. Only assets. I’m planning on making a cat toy that follows my cats around and bug the hell out of them. Dual use, ha ha.",

[Folklord36] on the Acidmods.com forums has been working on a
PSP lapto
p that we think gives the
PSP GO a run for it’s money
. Sure it may be a bit bulkier but it has a full keyboard, thanks to an Xbox chat pad. The original psp is on the bottom. The screen and speakers have been moved to the top. He says there are still a lot of things that need to be finished, but this is pretty impressive already.
[thanks Robin]

The new
Palm Pre
cellphone has a “media sync” feature which lets the device sync with iTunes in a fashion identical to an iPod. Last week [Jon Lech Johansen] speculated that this was
not done in cooperation with Apple
and that Palm was spoofing the iPod’s USB controller. This was confirmed today when a tipster sent him a
screenshot of what the device reports
in both standard and media sync modes. The Palm Pre reports its Product ID as iPod and Vendor ID as Apple with a few other changes. [Jon] notes that it doesn’t change the root USB node, so Apple should be able to block this behavior with an iTunes update. With Palm already pulling tricks like this presumably through software we wonder if this will become a full-on arms race.

When an unsuspecting person walks up to
[Rob Ray’s] ATM machine
, they are greeted with a surprise that doesn’t involve giving them their money. When they insert their card, the video above plays followed by a game where you control a beaver trying to save money during a recession. Surprisingly, people usually found it humorous and didn’t immediately freak out that their card was in a machine that wasn’t their ATM. His site has all kinds of pictures of various users as well as the construction of the project.

Thanks to Hack-A-Day for the post and appreciate the comments from you all.A few comments/responses.The ATM doesn’t scan your card, you could stick a library card in there and it would work. I’m just looking to see if you break the beam and throw the “Card Inserted” pin high.I considered reading your name off the card and text-to-speeching it into something completely goofy but I found most cards don’t actually store your name anymore – even though it’s in the spec. Out of about 10 different bank cards I tried, only one had the name on it. And it was a fair chunk of work for only a so-so feature, so that feature hit the cutting room floor in effort to get the piece done.People are indeed daft enough to put their card in any old machine – which is something I wasn’t sure about. It was tough to make the ATM look _enough like_ an ATM to trick people and then also be kind of crappy so people would immediately know it’s a joke once the video comes up.Also I wanted to make the gaming interface (up, down, left, right, jump, fire) NOT obvious before inserting your card but then obvious once you knew it was a game. So I left the numbers off the buttons. Also I thought this might be one of my “outs” if I got into trouble with the law.I was amazed how useful it is to Not Be A Dick.I had thought it might be cool to hold the card and not give it back until the end but that would make it an entirely different statement. Also I thought that holding the card captive would be so distracting to people that they wouldn’t even want to bother playing the game. They would just be pre-occupied wondering if they were going to get their card back.Thanks again for the comments. Feel free to fire more at me if you have any.Also if you dig my piece you might be interested in Radical ATM Service which a friend of mine at Molleindustria helped out with and launched last month as well. It’s cool to see more ATM art out there. Heh.– RobThey take the more “radical” approach by holding onto your card and forcing you to read some propaganda. They’re athttp://radicalatm.com.ar/blog/",

Phototransistor Multitouch With A Twist

[Alex] sent us this project he’s working on where he’s building a
phototransistor based multitouch input system
. Though many people have built systems with phototransistors, most of them are quite large and very sensitive light and dark variances. [Alex] has done some fancy background subtraction through software. He believes his is the first to do this. As you can see in the video after the break, it seems impervious to the lamp he is moving around, and still fairly sensitive to his hand. We’re curious to see where he takes this one.

The purpose of this was to test a bunch of different phototransistors to see which one worked best for my purposes. I am currently waiting on BatchPCB to send me my circuit board so I can begin work on a larger one. I have also tried using lasers instead of LEDs(so its an LLP effect instead of a DI effect). That works really well, but not so much for this specific example because the rows are spaced so far apart.Thanks everyone!",

Remote-Exploit.org is releasing
Keykeriki, a wireless keyboard sniffer
. The project is both open source hardware and software. you can download the files on their site. Right now you can’t get a pre made board, but they plan on releasing one soon. The system can be upgraded with “backpacks” or add on modules. One of these is going to be an LCD that displays the keystrokes of the keyboard you are sniffing. Another is supposed to serve as an interface to your iPhone. Right now it has the ability to decode Microsoft wireless keyboards, but the Logitech pieces should be added soon.

Look at this awesome glove. This awesome glove is used to control tetris. Yes, you read that right, it controls tetris. This was a final project at Cornell in the summer of 2008. They built this glove to do
gesture controlled tetris
. With all the announcements of the
PS3 motion device
and
Microsoft’s project Natal
, it’s nice to look back to our very recent past and see some alternative user input. These people are using accellerometer data only, sent to the computer wirelessly.

I had one as a kid…and it controlled a lot more than tetris, and it would have saved these guys a ton of time to just reverse-engineer a power glove with a USB port and build an input driver controller.Apparently this version uses a wireless connection instead of that clunky old PowerGlove sensor that wrapped around half of the TV, so I’d suppose that’s a plus.Leave it to college kids when it comes to wasting time. ;p",

Evil Mad Scientist Laboratories has
released the 2313 target board
. A business card sized development board for working with ATTiny 2313 microprocessors. We
saw them at the Maker Faire
, and thought they looked familiar. You may recognize them due to their similarity to the
Atmegaxx8 family board
. As usual, this is released as creative commons and source files are available on their site.

[Vik] sent in this simple little project. He purchased a $3 spy ear, a simple 3 transistor amplifier, and
attached a stethoscope end
. Little modification was necessary, mainly just scraping a bit more space in the microphone tube. The end result is a super cheap electronic stethascope that can be hooked to a computer or other speakers for multiple people to listen to.

These nifty looking goggles are
actually an instrument
. The guts of a pikachu doll have been splayed and mounted to the goggles. The controller is an external box that allows you to make all kinds of changes to the pitch and sample section. You can see a video of it after the break. We don’t really find this to be great music, but find watching the guy fairly amusing.

[Matt] wrote in to tell us about this project. He plans on travelling with his
MSI Wind and wanted better audio recording
capabilities. He decided to install an additional microphone and a preamp. He made a custom preamp and wired it directly to the motherboard. The microphone was then mounted in the laptop screen. The second microphone is placed opposite of the first, about 18cm apart which [Matt] claims gives it a
binaural effect
. We think that this might just classify as stereo though. Wouldn’t you have to seperate them with a barrier or dampening device for binaural? It doesn’t really matter though, stereo mics are a great addition to the MSI Wind, and he did it very well. He does point out that it picks up a lot of noise though. There’s always room for improvement.

The project was done on a budget, and it was simply a mod to the already average onboard sound. Had I wanted better quality audio, I’d probably have transplanted a good quality USB ADC into the Wind, and used decent, audio quality electrets and opamps.– The binaural effect is certainly enhanced by adding a barrier between the microphones, but a large part of the effect is due to the time difference between sounds reaching each ear.",

The circuit doesn’t actually produce a> gain that high due to the crappiness of the >LM358 and the fact that the electret condensors>are not perfect voltage sources.Could you please elaborate on your comments?a) I took a look at the data sheet for your opamps…I’m not sure what you mean by the “crappiness” factor and how that would effect gain. Theoretical gain should be on the order of r4/r1 or 1000x.If it does not produce gain that high, I can think of a few reasons. First, gain will be somewhat less for lower frequencies because C1 is rather small, and its impedance rises as frequency drops. Second, you’ve biased the op amp to 2.5 volts, and the opamp will saturate as the output approachs the supply rail. With a gain of 1000, that’s easy to do, as less than 2.5 mV on the input will cause clipping. The apparent gain will drop for any input larger than that.b) Does your comment about “crappiness” have to do with the op amp’s gain-bandwidth? I still don’t understand why you need a gain of 1000.c) Electret mike capsules contain a fet that tries to pull their “output” to ground. This current to ground is modulated by the audio hitting the mike. This causes a corresponding voltage drop across R11, which likewise varies with the audio. What do you mean when you say your mikes are imperfect “voltage sources?”d)… be *very* careful with the conclusions you draw from Spice. Spice simulations are not the same as living in the real world. Since Spice is only as good as the assumptions baked into the models, it is possible for a circuit to look great in simulation and fail in the real world. In fact, it is possible to build fully “functional” nonsense-circuits in Spice.Overall, good idea, nice project, very nice circuit board and nice mechanical implementation. The circuit needs some more scrutiny, I think.",

I’ve changed the title of the post on my travel blog.– The circuit was loosely based off the one here:http://www.reconnsworld.com/audio_singleicpreamp.htmland a few others that I found on the net. The final values of the feedback and input resistors were produced from a mixture of SPICE simulations and real world testing. I tried a number of resistors to produce different gains. The 1M/1K combination was about as high as I could go before the amp started saturating the ADC (or hitting the power rails, I’m not sure which).– Simulating the circuit with a JFET in place of the voltage source significantly lowers the peak gain.– The LM358 is fairly low bandwidth. The high frequency rolloff is soley due to the opamp. If it is replaced with a Burr-Brown or similar, it does not have this rolloff.",

After hearing that his video card might be repairable by heating it up to reflow it, this user did just that. He stripped it down and
tossed it in his oven
. It’s amazing how often this type of hackish repair works. We’ve heard of people using
candles on ibooks
, tossing video cards in oven,s and
wrapping an xbox 360 in a towel and running it for 30 minutes
to get it hot enough to reflow itself. Why even bother with controlled temperatures and exact measurements? What other crazy fixes have you had to employ? We had a Playstation that only worked upside down.

won’t win any awards for being something innovative and new, but we really like how it looks. The bar graph style display adds something to the project that a normal character display just wouldn’t. You can download source code and schematics on the site.

Liquidware has put together an interesting kit called the
WiNet
. It has a battery powered touchscreen controlled by an Arduino. Using an XBee shield, it can send commands to a paired XBee and Arduino attached to a computer. The computer can also update the touchscreen display. This is demoed in the video below. It’s a unique interface, but the TouchShield alone costs $174 so we’re guessing you’re going to be pretty damn confident in your project before you go this route.

[John Park] has managed to snag a couple interesting business cards at Maker Faire. The first is Adafruit’s
laser cut Spirograph card
. The other is a
ATtiny2313
prototyping board from Evil Mad Science; it looks to be the same style as their well-known
AVR target board
. We’ve also heard rumors that [Jérôme Demers] has bunch of resistor bending cards.
For more business card nonsense, check out: [Goodspeed]’s
smart card emulator
, [Mayer]’s
embedded gears
, and our
web server business card
.

[Soren Coughlin-Glaser] runs a mobile photobooth in the Portland area. It’s built inside of an
electric Volkswagen bus
. The conversion to electric hasn’t been easy though. He’s spent most of the last few months rebuilding it after an
electrical fire
. Last fall he installed a
9 inch electric motor
from Hi-Torque Electric after his smaller one
blew up
. We really like this project and look forward to seeing it back on the road… once he replaces his stripped transmission coupler.

Engadget has
video from the June 2009 episode of Qore
that shows the new PSP Go. It has a slide out gamepad, 16GB internal storage, bluetooth, and a memory slot of some sort. We’re naturally curious about its potential as a homebrew platform. Will Sony take the mature route they did with the PS3 and let you run Linux or will they continue the firmware arms race the PSP is known for? We’ll be hearing more about this platform at E3 next week.

McBlare: A Robot Bagpipe Player

We all want our very own personal bagpiper. Playing it ourselves is too much effort, and keeping a full time bagpiper around can be a pain. You have to feed them, clothe them, give them union breaks, etc. Luckily, modern technology has come to the rescue again. You can have your
very own robot bagpiper
. McBlare plays the bagpipe with technical proficiency that would be impossible for most humans. But lets hear it put some soul into it.

This sounds like old MIDI-generated music of the early 90s — very robotic, very precise, utterly dead. They might improve its sound if they recorded a human instead of just sequencing notes out of a machine, but I think the solenoid nature of the fingering will prevent this from ever sounding good. Bagpipes are one of the most “analog” instruments ever, and digitally precise notes don’t become it.Maybe if they had used stepper motors or something else to more closely mimic human fingers, it’d help improve the sound greatly. But then again, this is “hack-a-day”, not “build-a-useful-musical-instrument-a-day”.",

Rapid Prototyping With Sugar And Lasers

After
the recent announcement
of the re-release of the candyfab, [4volt] had to give a run at melting sugar with a laser. It turns out that a
40w co2 laser works great
. They don’t currently have a method of layering, so everything is one layer currently.You can see the results of different speeds and power ratings on the site. The next party they throw will have some pretty fancy tasty treats.

Ok, there aren’t any usefull applications we can think of for this one, but we want one really badly. This is a combination of a miniPOV, some UV LEDs, a CNC rig, and some glow in the dark paper.
The Ghost matrix
works similar to a dot matrix printer where it flashes the UV light to activate the paper. The final effect is very nice. Great job on this one.

This month’s Wired magazine has an
extensive profile of [Marc Weber Tobias]
. He’s a professional lock picker that delights in coming up with new techniques for taking on high security locks. In recent years, he’s run afoul of the US’s premier high security lock manufacturer, Medeco, by publishing
Open in Thirty Seconds
with [Tobias Bluzmanis]. Medeco still denies that this is even possible. Wired decided to to test the team by purchasing six new cylinders and timing them. Each one was open in under nine minutes. You can see a video of this on Wired’s site.
Last fall we covered a
decoding attack against Medeco locks by [Jon King]
.

For God’s sake it is the 21st century, video editing such as cutting, pasting is as smooth as most courts would not allow it as evidence unless a digital camera was in use. Digital video or photography cannot be edited without leaving obvious forensic trails! It is almost like watching infomercials at 4: am on TV about how everybody can make millions of dollars without any educations and experience. I know for fact that these “trade show experts” are pinning the cylinders in advance with two or three pins and Valhalla the lock just opened in three second. Locksmithing is based on the law of physics and science and not on “secrets that can be reviled to the public for $9.99 and implemented without experience and knowledge of the trade. Marc Weber Tobias is an attorney not a locksmith by any stretch of imagination. I could not find any evidence of his self proclaimed “expertise in locksmithing or lock picking on the web. And why is he picking on MEDECO? Why not ASSA or ABLOY or MUL-T-LOCK? I personally know people that claim they can “open” high security locks like Medeco and Mul-T-locks. But I have yet to meet the locksmith on the job where they can demonstrate how to pick high security locks like Medeco and such. Most so called locksmith can’t even pick a standard lock open let alone complex high security locks. Drilling a perfectly good lock open does not make you a locksmith. Neither “picking high security locks open” on a video tape on the internet. When you see a lock installed on a door the first time in your life, and the customer that you charging $130 is waiting for you to pick it open in three minutes then show me what you made of. The major difference of Medeco locks as oppose to conventional pin tumbler locks that Medeco pins are rotated and elevated, either to the right or left or center in various degrees. While conventional pins are only elevated. Now as far as picking Medeco locks open, how on earth would you know the possibilities of the direction and the degree of the angle of rotation, without taking the lock apart? The tolerance is about two thousand of an inch, half the thickness of a US dollar bill. Mathematical possibilities of six pins, each one can rotate three different directions in several degrees. How many thousands of possibilities are we talking about here? There is a difference between professional locksmithing (not residential locksmithing) and internet lock enthusiasts. One caries responsibilities, people’s life and safety depend on. The other is merely a hobbit.",

"content": "How many of you people who are standing blindly and gloating about Mark Tobias claims about picking Medeco locks, are actual skilled, knowledgeable licensed Locksmith with any real work related experience. Making ridiculous claims about lock picking on videos is not real work related experience. Having graduated on the top of my class from New Jersey School of Locksmithing and worked five years in the field of Institutional Locksmithing. I know facts from fiction, and reading peoples’ (novices) responds to Tobias’s claims makes me smile a little bit. How many breakings have you heard about where sophisticated thieves by passed Medeco locks? Or Tobias is the only one here with brain. Sure let’s knock Medeco; but wait we can offer you a better high security lock that is better. How is Mark Tobias employed by? How is financing all these web sites where Tobias is connected? Has anybody ever witness Tobias opening Medeco locks on somebody’s door. I watched some of Tobias videos and what I find interesting that they did not insert and turn the original key in side of the Medeco cylinder (“before picking”) to let us know that it is actually pinned up. Then they should’ve inserted a key with the same keyway with different cuts showing that the wrong key is not turning the plug. Just to see that there are actual pins inside the plug. Or how about inviting us Professional Locksmiths to these events and let us pin up the Medeco cylinders and cut keys any combinations we choose to. PC it is very easy to pick any lock with only a couple of pins inside. I understand that some of you will be offended by what I’m saying but it is very hard to reason when people don’t even know what they don’t know about what they’re making claims. Locksmithing is not something that you can become proficient of by surfing the web no matter how long you’ve been blogging. How many of you dumped the inside of a mortise lock and put it back together in a half lit damp and cold hallway sitting on the side of the stairs while people walking by and your phone is ringing off the hook in about three minutes? On my web site I will offer any body hundred dollars that can pick open a Medeco lock located on one of my customer’s property in fifteen minutes or less. Then it will be recorded on a digital video camera so editing is going to be impossible without obvious forensic evidence. Good luck every one and good night.",

After making a few units for the new
Discovery t.v. show called Weaponizers
, [Jeremy] decided to
release this video
showing how to modify a golf cart for radio control. The radio and controller are basic off the shelf R/C gear, running some linear actuators.

Another Cornell final project,
Weather Canvas
aims to make watching the weather a little more pleasant. Data is captured via a thermometer, humidity sensor, anemometer, and a Hotwheels radar gun turned precipitation sensor. Once it’s captured, it’s transmitted to the LED matrix inside which displays pretty patterns to convey the weather conditions. They have set images, like icons, that mean different things.

[Nate] hates keys. He’s gone through a lot of effort to remove them wherever possible. He has a keypad at home and a keypad at work, but he still has to carry car keys. His solution is to build
a device he can carry in his pocket that will unlock the car via RF
. To do this, he’s utilizing the guts of a Nike iPod puck along with an Arduino and an iPod serial board. He has managed to get this all working, but still has to carry his key to actually start the car. We know what his next project will be.

[Segwaymonkey] picked up an arduino based drumkit circuit and needed a kit to place it on. He worked up a pretty cool design and had it
laser cut out of acrylic
. The cool part of the design is how he delt with the head motion of the drum. Each head has 4 “springs” that were also cut from the acrylic. The
Arduino based drum circuit
sits on a little pedestal in the middle, as though it were on display. We really like the design, but we have to wonder if a little noise dampening on the heads might be a good idea. He hasn’t released the plans, but says he might once he gets it perfect.

[Pete] has put together a
fairly simple writeup on building a wireless USB tether for your DSLR
. He’s basically using a pair of USB wireless adapters and a battery pack. In his original version, he did some slight modification to the dock that powers the USB dongle, adding his own battery pack too. He notes that this whole project can be done without the effort he put into it, at a little more expense. The only improvement we think would be nice would be a better way to package it to keep it out of the way while you shoot.

Canonical, the main sponsor Ubuntu Linux, is developing an
Android execution environment
to allow android apps on Linux desktops. There’s still a lot of work to do to get this running smooth, but they do have a proof of concept functioning, as seen above. This could be very nice for those who have linux netbooks.

Click-install-done! Great! Greatest OS!!! Eh?!What did you click on? Was the product authentic? What ELSE installed? Dunno?You do get a lot of errors under Win due to their obscure or not-existent permissions system on earlier versions but typical win user do not see them that often because (s)he runs everything as an admin! What a beautiful and advanced solution. I feel their pain, you try to be a non-privileged XP user and tell me how you feel!Yet you are right somewhere – installation of binaries generate less errors than compiling it from source. That only means someone pre-compiled that binary for you and you are not aware of errors if they existed.But this easiness would not be my number one concern in this scenario.Ubuntu has a repository system that supply you with clean and signed binaries pre-compiled for YOUR system. The only one problem that linux suffers nowadays is some software makers do not wish to compile and test their product for linux. It is not the same as something doesn’t work, I hope you understand it.Vlad.",

[Scott] runs gamesbyemail.com. One of his biggest hurdles was producing real random numbers for the games. He had tried various methods like math.random and random.org, but kept getting complaints about the quality of the random numbers. His solution was to build
an automatic dice roller
. His
initial attempts were made from Legos
and were never quite reliable enough to be put into the system. The Dice-O-Matic however has proven to be a random number generating monster. It is 7 feet tall and capable of 1.3 million dice rolls per day. Wow.

[John] sent us this nice little project. He shows us how to
create a motion activated alarm that plays the Mario Brothers theme and flashes some lights
. He’s using an ATTiny13a for the brains, and a cool mario mushroom candy tin for the body. You can see it in action after the break.

Remember those days, back in the arcade, where games with a unique control scheme also had a controller best suited for them? There were rolling balls, joysticks, dials, all sorts of inputs. Consoles have maily relied on their standard controllers, relegating alternative inputs to be strange collectors items. Some games just need a specialized controller though. For example, Katamari Damacy.
[Kellbot] has made one
that we think suits the game very well.

No real reason for it.I wonder if you could hack up the control scheme of the game (using an action replay or gameshark) to use a single standard mouse plugged into USB (put all the programming onto the PS2 platform), or maybe even using the Playstation mouse.I would love a beach-ball sized controller floating on an air base, perhaps with the right optics you could focus a mouse on the floating surface, you could position an IR break sensor below it, and pressing the ball down would activate the presses (I forget, what were the presses used for again?)Also you could figure out a way to translate the inputs to one single mouse using logic. Basically reverse-engineering the software the game is using to convert 4 input axis into 2 motion axis, then putting that on-board the Arduino.Also I have converted a standard PSX controller to have the left analog stick where the d-pad was, after I got Katamari I started wanting to move the left stick up to where the action buttons were, kinda like a handheld version of this:http://curmudgeongamer.com/2005/10/ace-combat-and-dual-analog-flight.htmlPS, love the music, that game is freaking awesome.",

[Florin] was given the task of repairing a GPS unit that wouldn’t boot up. What he found was unfortunately a bad processor. Fortunately, he was able to
make a project out of it
. After scavenging the good bits, the GPS module and the LCD, he set about making it a USB device. He now has an EEEpc with GPS.

Many people find themselves frustrated when working with headphones. The tiny coated wire can be a real pain to work with. They are so very very small, and usually coated. We generally just end up doing a quick “sand and tape” which just isn’t very high quality. [Alex] sent in
some tips that can really help you get those repairs or modifications going
.

They cost around three bucks.The most likely reason soldering new wires didn’t work is either because there was a failure at a different point in the wiring, which could have been solved by checking continue unity with a multimeter while manipulating the wires, or by realizing the headphones need new wires or outright replacing with new units. Or it could be that the damn coating on the wires screwed it up yet again.",

The stuff that burns off just kinda floats on top of the solder blob on your iron, and you wipe the iron off easy, and the enamel gets tinned with solder. After that, solder the wire as you normally would. I wouldn’t be concerned at all about organics damaging your soldering iron (more concerned about breathing it, but that’s another issue)–hell, there’s burnt flux on it most of the time, anyway, and it tends to float to the surface.I see no point to the whole pencil torch nonsense, unless your iron isn’t high enough power, in which case it is possible to melt the rest of the insulation since you won’t be able to do it fast enough. the thin tiny wires they use aren’t very good thermal conductors, and don’t melt the rest of the cable that quickly. i’ve fixed quite a few headphones without that extra nonsense.there’s always also the possibility that non-solderable enamel was used (basically the burning/melting temperature of the enamel is too high for the soldering iron), but i haven’t encountered that in headphone wires at all. in that case, using a pencil iron makes sense.",

Canadian Tire for one ex, and not very expensive)Use just a little bit on the tip of the stranded wire and it’ll absorb into the cabling.Get some solder on your ironBriefly touch the iron to the tip of the wire, and the solder will quickly and smoothly flow over the tip of the wire.Once you tin both ends like this, you can then attach them.The key is to be quick and not use too much liquid flux, so you don’t burn too much of the wire away. You’ll find that tinning wire ends with liquid flux, especially stranded cable, works excellent since it practically pulls the solder into place.Yes, there’s solder with a flux core, but trust me when I say this works better.WARNINGLiquid flux is an acid. Don’t get any on you. If you do a lot of work with it, keep some solder remover handy. (the remover is a skin irritant, but better than acid)To apply, I suggest either long stemmed Q-tips, or even easier, get a small glass bottle with a plastic cap and applicator brush.

But first let me say not to knock on the flame idea because it is the very idea I used before this one. I found the wires tend to get brittle and charred and because the wire is so small the heat distribution makes the fall off so abrupt the usable area is also brittle so for maximum strength I came up with this.1. I tin the tip of my soldering iron and form a small puddle (1-2 mm ball) of solder on the tip2. Then as I am holding the wire (BEFORE ANYTHING IS ATTACHED) I take it and rest it in the puddle until you see the acrylic boil to the edge of the solder3. Now because I form the puddle of solder the acrylic waste does not stick to the soldering iron and you just have to tap the excess into a ashtray or bowl or your soldering station waste trayWhat you accomplish by doing this is you tin the wire wherever you are connecting it to make for faster soldering once your working with your component to keep down on heat damage for the wire and component (as we all know brittle wires and burned up plastic sucks when your working on those “one shot” projects). you also benefit from have the acrylic coating all the way up-to your solder joint.Things I have repaired:Xbox 360’sTurtle beach Gaming HeadsetsTouchscreen car dvd playersCar stereosLED TV’SProjection TV’sLaptopsDesktop ComputersStandard EarphonesPolice Lighting EquipmentSurveillance camera EquipmentECT….",

I used a backup cable I had lying around that had been slightly damaged but was still useable. Otherwise would have been an expensive risk to take.I just twisted the tiny wire’s together in their coating using my fingers, clipped the ends into a helping hand setup, tinned the iron, went over the wire twist a few times with the bead, trying to apply the solder and heat evenly and replenishing the bead with more solder as needed (it might fall away before the wires are hot enough but it is still doing the job of melting the sheath). Heat shrinked them all separately and then together – done! Happily using my modded headphones right now!",

I used 22swg 60:40 Tin/Lead multicore solder. I heated the join a little longer first and took a minute to make sure the solder flowed into the wires. Be careful no to create a river of solder all over your jack plug! A little extra plume of smoke makes it obvious when you’ve burned away the enamel.Don’t use the flame idea, soot is even harder to solder over than enamel and you will strip more of the coating than necessary. Enamel coating isn’t a pain – it’s a near magical method of making sure that there’s insulation everywhere along the wire except at the join. So much easier than stripping tiny plastic cores from fine fibres!Also for the record – I didn’t remove the nylon thread either, just let it melt into the solder. Can’t say how this would go with lead free solder, but a bit of lead poisioning is well worth any inconvenience of using lead free :)To make putting the wires into the holes on the jack plugs a little easier, I tinned the tips of the wires first, just to keep them together, not at the final join point. Altogether very pleased with the job and sound quality of the finished product.",

At Berkeley, they’re coming up with new ways to make their itty bitty hexapods. These are basically
tiny flatpacked bodies cut from cardboard
. The end goal is to not only make them smaller and faster to build, but to reduce the friction in the joints. You can download the files on their site as well as download movies of them in action. For a larger and somewhat less complicated flatpacked robot, check out the
flatpacked 2 motor walker
.

There have been several attempts at bringing Dungeons & Dragons up to date with modern technology. Most attempts have been in the form of computer games that somehow fail to capture the essential experience. This attempt, however seems to add some techie flair to while keeping the game the same. [Itay] has
built some digital dice
. Simply choose how many sides you want your dice to have, then give it a shake. OK, a random number generator isn’t that groundbreaking, but he did have to do some pretty intense soldering. The LED matrix is pretty cool, but we like looking at the back. You can see it in the video after the break.

[Kyri] has made a simple circuit to do
color detection using an RGB LED
. Simply set the LED to the color you want to detect then wave the object over it. Another LED will light up if the object is the same color as the LED. The detection is done by a photo resistor. The theory is that an object will reflect more of the light that matches its surface color. She shows that this kind of detection could be useful for sorting in robotics.

Let me try:(skip this paragraph if you are scared)Multiply the light source’s color spectrum with the material’s reflectance spectrum and you get the “color” that reaches the eye/camera. Now multiply that with the response spectra of the cones in the eye or the camera’s CCD chip and integrate. (By multiplying these functions i mean something like f*g(x)=f(x)*g(x).) Now you have a color value.With your method you will get values that look about right in most cases, but consider some material that has a reflectance spectrum with one peak (say, yellow) between two peaks of your leds (say, red and green). This will show up as black when illuminated with the seemingly yellow light of the combined leds, although it appears yellow under full-spectrum light like sunlight.(ok, it will not be black since the peaks are of some width and maybe even overlap. But it will be darker than it should be, which is my point.)Read wikipedia, it helped me.",

D-Link Router Captcha Broken

We reported last week that D-Link was
adding captchas to their routers
to prevent automated login by malware. Unsurprisingly, it doesn’t work all time. The team from SourceSec grabbed the new firmware and began poking at it. They found that
certain pages don’t require the authentication
to be passed for access. One of these is WPS activation.
WPS
lets you do push button WPA configuration. Once activated, any nearby client can request the WPA key using a tool like
WPSpy
. Only user level credentials are needed to pull this off, so changing just the admin password won’t prevent it.

"content": "@googfanThe whole point of malware bots breaking into routers has nothing to do with stealing peoples wifi.The primary purpose of a malware bot breaking into somebodys router is to modify the routers DNS tables so certain site requests can be manipulated. For example every bank web address you type in is redirected silently in the background without you even known and without tipping of any of your browser security or phishing filters to a rouge site which then caputres your details. And you wont know a thing about it becouse the site looks identical, you just wont be able to log it, it will take your details and then say “Sorry – Server error, try again later” or something like that.the other reason malware Bots would try to break into routers is becouse Firewalls can be a pain. However if you break into the admin area of a router you can practically disable the firewall, allowing a human operator to them zombie all the PC’s behind the router firewall at leisure.HAcker/cracker leaves this bot running to do the leg work for him over night, wakes up in the morning and has a whole screen long list of address’s where the routers now forward all bank requests to silent phishing sites and, a list of routers than have possiblely hundreds of avaliable PC’s ready for dronning.Considering MOST pc’s are behind external modem routers these days, Malware has addapted.Malware that directally and automatically compromises your gateway to the internet is this fashion is as frightening to us computer security guys as it is interesting.Can gurantee once a router is hacked, your’ll never be able to trust any site again.(Ask yourself this question, how many people do you know with broadband…. and how many of them would even know if somebody had loggin into their router? 90% of the people I know have never touched the thing after the initial setup.)They own your DNS.Trust me router bots are not “Pointless” they are frightening and the next big thing.",

Here is my question about all this Captcha requiring you to login and this malware bot.First thing is most routers by default dont allow you to access the config from the WAN port, only if you are on the LAN. So unless you go in and change this, or, this is something that has changed in some these new routers I think that would prevent outsiders from gaining access.Now if you have an open AP, and, a client with an infected machine comes on the AP then I guess the Captcha could add an extra level, but you already have issues with an open AP and allowing people on your “trusted” network.Also I thought most new routers require you to set them up properly to work and no longer “work out of the box” to prevent default password.",

[Marc] submitted this project he’s been building. It’s a
web enabled HVAC monitoring system
. He’s using a pic-web development board with a custom I/O daughter board to control the HVAC system. The project allows for the system to be monitored and controlled via the web. It should be able to interface with most commercial and residential systems. As usual, schematics and source files are available on his site.

I am more interested in monitoring and receiving alerts, than I am in actually controlling the temperature. This has real product potential if it can generate email or SMS alerts when something is wrong with the hvac: 1) Is it cooling properly, according to tenant thermostat settings? 2) is it heating properly? 3) is there any degraded performance accruing over time? In my approach (which I never actually implemented yet) all this information could be obtained by monitoring supply air temp vs return air temp. The Delta-T will tell you if the unit is heating or cooling as expected. It might also tell if there is a filter blockage, a freon leak, or even a severed outside compressor control line (lawn crew weed whippers do this ALL the time). Also would need to sense the setpoints of the thermostat, instead of control them. If an email alert can save me from replacing a burned out compressor, or when a filter needs replacing it would be awesome.",

I’m working on a project currently but it’s not ready for public yet but it contains multiple temperature sensors that can be installed around the house. Multiple points per room preferably. But in conjunction with some over the counter “vent” boosters. It allows for a much better control of ambient temperature of the entire house hold. I’m looking into adding some more intellegence into the system to account for past history and trends for current time of the year to be able to anticipate large temperature changes. As well as some angle sensors on the doors and windows that are actually used. Total dynamics of the house flow can then be monitored and controlled. The system is modular so it’s scalable to any size home. The use of standard vent “boosters” allows for retrofitting and upgrading instead of a complete HVAC system rebuild. The system also takes into consideration the total energy use and everything can be scripted to react to any any energy based constraint set. The control of the devices is done through what some may recognize if they use video editing software. A timeline based action script graphical interface allows you to set states of the device in a 24hour window based on whatever factor the user decides to use. Which can be: temperature, energy use, day of year/season, etc. More info coming soon.",

Ever wanted a projector for your iPhone?
How about a laser projector
? These guys did, they made one using an individual laser for each pixel. They have a 5×7 grid to work with, so they have to keep it simple. Well, as simple as it gets with 35 lasers. We think maybe a
scanning POV style projector
might be more efficient.

The
table for electronic dreams
is an interactive table that is sensitive to electric activity. Though it looks similar to the
table built by EMSL
, this one lights up based on electromagnetic fields. You can get the schematics and such from the instructable, but there is also a video located at the bottom of the
project’s home page
. It would be really cool if the effect could be localized more.

. What is interesting about this display is that it has a dual motor set up. The original motor didn’t quite have the power to get the display up to the required speed. A second one was added as the shaft of the rotor. Yes, one motor is actually spinning another motor that is spinning the display. Well, it’s hard to tell from the description. The original motor might be completely unused, but left in place.

The key point is that second motor’s shaft is turning relative to the second motor’s housing – so it has a speed of, say ‘s2’. If the housing is rotating at ‘s1’ relative to zero, then the second shaft is spinning at s1+s2.The other thing you said, about friction – depends on the type of motor. An unpowered permanent-magnet motor will induce a force that opposes the driving force, which would equate to wasted power in the system, like you said. However, the losses in a system where both motors were powered would be minimal. They would be very wasteful as the started up, as the motors would ‘slip’, but after that they would eventually stablise.",

Eye Tracking Via Electrical Impulse

"eye tracking"

Generally when tracking eye movement we use various methods that require sensors being pointed at the eye itself.
This approach is quite different
in that it is sensing the “electrical potential of the cornea”. We have no idea how this works, but it looks pretty cool.

If you highpass at .1Hz or so, you can get some decent tracking, but it’s only accurate to a few degrees, which can translate to a significant distance on a monitor. Plus, if you filter DC out, then you can only tell when you move, since your signal will go in one direction, and then level out back to zero. You’d use that waveform’s magnitude to figure out how far your eye moved.There’s a reason we don’t see EOG equipment around very much. Still cool stuff though.",

[phreakmonkey] got his hands on a great piece of old tech. It’s a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to
see if it would actually work
. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn’t working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It’s still amazing to see this machine working 45 years later. He’d love to hear from you if you’ve used a similar device.

Forget about machines that can replicate themselves, what we want is a machine
capable of making an 8 inch wide hollow torus out of sugar
. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the
new wiki site
.

Like many pet owners, [Pete] was curious about his little furry friend’s habits while he was gone. He decided to
build an RFID tracking system
to monitor their positions. This
data would then be available on the web
. An Arduino handles the communication of the data, both to twitter and his personal cat tracking site. We were a bit surprised to see that the only data transmitted on the final project was whether the cat was inside or out. We’d like to see a heat map of the cat’s activity in the house.

. This time, focusing on cheap tangible interfaces, mainly trackmate. They want as many people to join as possible, even if you’re not comfortable with code. We’ve covered the
construction of the trackmate surface
before, now build one and get in there and contribute.

[Will] submitted his ski goggle mod. He has
mounted an Oregon Scientific ATC3K digicam in his goggles
. This should make recording ski trips a lot easier. Most of the electronics fit just fine in the mask, though he did need to use an IDE cable to extend parts of it to the custom pack mounted on the strap. We’re also curious how much wind noise he’s going to get on that microphone.

Snoozy the Sloth clings to you and sleeps
. While this may sound easily done, the maker wanted the sloth to actually simulate breathing with exhaled breath to add to the realism. To do this, they had to build a “respiratory system” out of a rubber glove, a solenoid, and a couple pumps. This kind of toy can be very beneficial to special needs children. The lifelike and calm behavior helps the child connect to the toy. The pumps and solenoid are said to not be too distracting, but we are curious just how loud they are. This seems well executed, and much more sloth like than
slothra, another sloth
toy from last week. Were these guys in an Arduino powered sloth making class together?

[Sam] submitted this fun project, a
Punchout interface that you actually punch
. If you recall, we’ve done a
Punchout interface that you punch
, but this one takes it a step further. Instead of being a blob on a desk that you’re mashing around, the new one is a Slam Man boxing dummy. They’ve mounted the buttons on different areas of the dummy so you can punch him to completely control the game. As you can see in the video, it seems to work ok, though we doubt the buttons will hold up very long under those conditions. They do say that this is just to hold them over till the Wii version, so maybe those buttons will last just long enough.

A good portion of the buttons are actually place in the foam rubber, so that absorbs some of the punch force.Arcade buttons can stand up to a pretty good beating. How many button smashers slam these same buttons down playing fighting games at the arcades?Would love to see someone improve upon this even more!",

I too worked at an arcade in the late 90’s and the buttons were never a problem. The joysticks may get a little sticky, but you never had to do more than clean them up. Those things are sturdy!a foot pedal to block would be neat, if it could be stolen off a time crisis that’d be awesome. The problem with footpads is always movement. It’d have to have some weight behind it (or be attached to the dummy) in order to keep it in the same place all the time. If it moves around, it makes it impossible to know where to push without having to look down. Reason I know this was I made some contact sensors using foil and foam rubber, where when you step down on it it compresses the foam rubber and connects the two pieces of foil. Even though I made quite large pads, since they moved around some while playing, I had difficulty dodging.",

I guess the solution would be to maybe make a box that housed the button, then place a board on top with some springs or something to hold it above the button that you could press down. That would probably give it the weight needed plus the size. However, you have to remember, in punchout you have normally just a fraction of a second to hit the button before you end up getting punched. Do you think you could lift up your leg and hit a button fast enough with your foot before the punch hits you? Watch the video to see even how quick it seems to come even just using a punch.",

Here’s another hacked Nerf Vulcan rifle. This time it is
an automated sentry gun
. You must present it your badge, if no badge is found, you are assaulted with a fiery storm of small nerf darts. All encounters are logged and a photos are kept. This was a final project at Cornell, and for once it
wasn’t ECE
. This was for CS1114. They did a pretty good job with the tracking, now they need to add some more interesting voice options to it.

Here’s a cool tip, sent in by [Martin]. He has put together this very compact package for an
animated 8×8 RGB LED array
with a tiny footprint. It is controlled by an ATMega16 powered by 2 small lithium cells. While it may not be quite as small as the
space invader button
, it seems to have a bit more animation horsepower.

[NRP] sent us a few of his projects. The most notable of the bunch was a school project funded by Disney. They were to make some kind of
interactive entertainment for people waiting in line for rides
. They decided on a wand style interface. Each wand has an accelerometer, an IR LED for tracking, an XBee unit, and a few buttons for interaction. They wrote some custom games and a multi person white board to test it all out. You can see those in action, along with a space themed pong game in the video after the break. Even though this was funded by Disney, you can still find all the
source code and schematics
, available for free.

The “wand” controller will probably be for sale, and/or included with multi-day passes and vacation packages. Your own “wand” will, conveniently, have a kind of RFID in it as well. This will allow them to use them to:a) track park utilizationb) use the wands in an e-commerce way – quick check out, automatically route to room thing. Imagine being in a gift shop and using the wand to buy things which are then just sent right to your hotel room. No waiting on lines to check out.c) track your “score” at games, and sign your “artwork” (which may help with the problem of inappropriate drawings somewhat). I could see them structuring treasure hunt contents where you use your wand to go to different attractions to collect points or clues.In fact, imagine a treasure hunt/points system that changed in real time based on park utilization. The clues could re-order or change their weighting to help balance the flow of people in the parks. A particular attraction is under utilized? Make more clues point there for a few hours.Frankly, now that I think of it I’m surprised they haven’t done it yet.",

No one will ever accuse us of being Windows fanboys; we’re certainly fans of
netbooks
though (or anything cheap enough that we don’t care if we accidentally burn a hole through it). We’ve heard from quite a few friends that Windows 7 is actually an excellent operating system to run on a netbook and is a dream compared to XP. Gizmodo has compiled a
guide to getting the release candidate on your lightweight machine
. It’s available now and will work for free for a year. The image is 2.36GB which you need to dd onto a USB device. They recommend at least an 8GB drive, but anything smaller than 16GB and you’ll have to use Window’s compact utility to save space. Other than these space considerations, the install appears to be easy. Let us know about your experiences using Windows 7 on your netbook.

I don’t ever run third party security apps, since honestly they’re not necessary if you’re careful, and they’re even less necessary when you run off the UAC architecture / much improved “not-giving-admin-rights” to your default user in windows vista (and i’d assume windows 7). I tried to implement this in windows xp (with the run as and all that) and it’s a total pain without something like UAC. Keep in mind that Linux and Mac OS work the same way with not making every user have “root” access by default, and that this is a big reason why they tend to be more secure for the average user.",

This did not solve the problem, but your suggestion did!!I can now use a much more respectable screen resolution of 1024×768, thanks so much! I’m hoping that I can use a similar method to get my PCMCIA wireles adapter working now.I can now say I am quite happy with W7 itself, evene thoguh I haven’t had that long to explore it in all it’s non-tiny glory. It runs much faster than my old XP installation, though of course that’s not a fair comparison.I can’t use any Aero effects of course, but as subbota said, it is much better at switching between tasks, so it seems much faster.",

[fibra] has been slowly building a
custom controller for his motorcycle
. It’s an automated chain oiling system that varies application based on RPM. The LCD can show wheel RPM, voltage, time, date, air, and engine temperature. A separate driver board has a MOSFET for controlling the oiling valve. The real gold here is the attention to detail. He built a one off circuit board. The case is laser cut acrylic that he then shaped. The box is molded smoothly into the original instrument cluster using epoxy. It’s excellent work that could be mistaken for a commercial product.

The belt is 5″ wide though.as for friction, a chain “consumes” more power just turning it than the belt, due to its having hundreds of moving parts.The belt, pulleys and idler weigh less than a chain and sprockets, and have no backlash, aka “chain snatch”. hence a belt doesn’t require a cush drive to absorb shock loads. It also don’t require a tensioner assembly in the swingarm, reducing complexity and weight further.the reason more manufacturers don’t use belt drive is that it as much harder to change drive ratio. you’d have to have a new pulley set for each ratio desired.",

A thinner chain means more room for a fatter tire, and with a chain, adjusting gear ratios is a little bit easier. Also, a chain is easy to fix if it snaps: just pop a master link on the break.The trade off is that a chain requires more maintenance: oiling and tensioning (they stretch).Drive shafts require almost no maintenance, but waste more power than a chain or a belt.Belt technology is getting better, though, and I won’t be surprise when chain drives become obsolete.

[Daniel] sent in this project. He tells us it’s an
Arduino powered kid’s toy that “furiously swings his arms” when you squeeze his chest
. As you can see in the video on the site, furious is up for interpretation. It is a sloth though, maybe that’s sloth furious. While it is cute and we do applaud the effort, anyone with children will agree that this is a step down in destruction for a 3 year old. You’re going to have to spice it up a bit, or give it a timer and make it free standing, make it roar or something to make it more appealing. What recommendations do you guys have to improve this toy?

Secondly step back and re-think things. i’m with eric on this one. not everything is required to be powered by a microcontroller. i have yet to come across a project which has demonstrated 1/4 the potential of a microcontroller. What is next? The Led flasher 2009, look ma only 30k of code @ 20mhz. Some of us imagined a future full of cheap computers, good free software and digital electronics everywhere. What we did not realize was that this would create a new type of want to be. Like others i am glad to see people working with electronics/computers but feel that there are unspoken rules to be followed simply out of respect. that respect seems to be missing nowadays. I equate it with the days of playing NES. You could either play a game or your couldn’t. Then suddenly a magical box appeared that allowed anyone to get to any level in a game, so even the lame could pretend to be great. If you can’t make the correlation here the finger is pointing at you. your video camera, new pc & software, and high speed internet do not give you skill. skill comes with experience, and experience comes with time. to end this rant i think this article belongs on hackaday to serve as a wake up call.",

[moris_zen] found himself with a hand full of Li-Ion batteries and no good way to see what their capacities were. He
built a this unique tester
really quick to get the job done. He’s using off the shelf components and a cheap pocket watch which he bought in Taiwan for $1. You hook the circuit up to your battery, click the button and the watch starts working. When it stops, you multiply that number by .38 to get your amp/hour results. Sure, he could have just used a counter, but this is an interesting approach. All he needs to do now is make a nice container to hide all of the circuitry. How could he change the circuit to make the end multiplication unnecessary?

Of course you will still have leakage current through the PNP transistor, but that should be negligible unless you leave this thing hooked up for weeks.As for making the calculation unnecessary, make it draw 1mA (yes, impossible with this circuit). Then see the number of hours it runs. :D You could make it easier though: change the total resistance (including parallel relay coil) to about 37.5ohms (drawing 100mA) or 3.7ohms (drawing 1A).

GM, in an effort to make their cars slightly more eco friendly, added a feature that puts your car in 4th gear when cruising along in 1st under certain conditions. This is apparently despised by many owners. I is despised so much, that you can buy a commercial product to disable it. That product costs between $20 and $40. Jalopnik has posted
a simple solution to disable this feature for under $7
. All you need is a replacement plug and a resistor. It’s really pretty simple.

The only reason to use the regular sequence of gears is to accelerate. If you’re coasting along in first and you aren’t accelerating, then upshifting to a higher gear lowers engine RPMs and makes the engine use less fuel. Coasting in first with high RPMs is incredibly hard on fuel.I happen to drive a big Dodge truck with a manual, so this isn’t something automatic or required by my drivetrain, but I do it anyway, as part of trying to get better milage. Driven in an average or typical manner, this truck gets about fourteen highway and eight city, but I can get 28 to 32 highway and 18 city by watching my RPM’s and being careful with coasting and stops.This isn’t a bug: this is a feature for people who suck at driving manual, which is sadly damn near everyone these days.

"content": "I’ll be anal about this. The following was written by Hib Halverson (Technical Writer for Internet & Print Media) who knows more than you.“The idea that skip shift exists for exhaust emissions (“EPA”) or guzzler tax (CAFE) is urban legend. Skip shift was designed in the mid-80s for the 1989 model year as a way to “beat” the Federal pass-by noise standard. At the time, the test required the driver to start out in first gear, then shift to the next highest gear and go by the microphones at wide open throttle. When GM began development of the 2nd Gen ZR1, it became obvious that, with an exhaust system that allowed the engine to make adequate power, they’d flunk the test, big time. An engineer named Jim Ingle (now retired) came up with the idea of preventing an upshift to second using an electro-mechanical device in the transmission controlled by the ECM which made fourth gear temporarily the next highest gear after first. This forced the driver to go by the microphones during the pass-by test at WOT, low rpm in fourth–and quieter–rather than at high-rpm in second–and louder.Skip shift has continued, with numerous calibration tweaks, to this day as a hedge against pass-by noise. It is possible that it contributes to fuel economy as well, but I doubt it. EPA mileage ratings are based on a specific drive cycle and I’ve never heard that skip shift contributes to that with any significance.When you learn the conditions under which the feature enables (some FSMs discuss that), it’s easy to drive around it and there is no performance driving situation–as long as you are properly driving the transmission–where you’ll get skip shift.The vast majority of drivers who have trouble with it are part-throttle, short-shifting out of first….hardly the way a Vette, a Porsche or any manual trans car should be driven.You can duplicate the pass-by noise test by starting out in first in a manner that meets skip shifts requirements, then, once you in fourth, go to WOT and accelerate. Have someone stand about 50 back from the road and listen. I guarantee they’ll see, uh….hear the advantage of skip shift. ”http://www.corvetteactioncenter.com/forums/c5-technical-performance/111112-skip-shift-eliminator.html",

Emissions are measured differently between the 2 continents as well, making it very difficult for a diesel engine to pass federal standards. Combine that with the fact that not all filling stations have diesel available, maybe 50% at most, and you see why diesels just aren’t as available in the US.I would certainly consider some of the excellent diesel cars available in europe, but in the US they kinda suck.

A Diesel-compatible car is soon to be built by the VW/Audi/Porsche/Skoda/Seat company (using less turbocharging and spark plugs for LNG, a stronger charge and no plugs for Diesel), and people buy those all the time, despite maybe one in six stations actually having the fuel.

It is more of a nuisance than anything else and I only get affected by it about 2-3 times a year, if that.First, it only operates if your engine is warmed up and you attempt a manual shift from 1st gear while under 20% throttle. It then moves a small bar up to block the ability to pull the gear selector into 2nd and instead guides it into 4th gear. When you hit 4th there is still plenty of power to continue on and it causes no safety issues. Besides, if you are putting along in 1st and short shift you are probably not looking for a whole lot of power after the shift either.Also, as soon as it goes into 4th, you can immediately pull it back out of 4th and pull it into 2nd, 3rd or wherever else you like.The net result: if it is a problem in your car then either apply the fix listed above or don’t buy a HIPO 350+HP car and drive like your grandma.

Lara, the robot pictured above, is the
first humanoid robot to pass security and have her own seat on a plane
. The reason she had to travel via airline was that FedEx had lost and damaged her on previous trips. On the way back from
Robofest
, which she placed 5th in, security didn’t really want to let her on the plane. They’re lucky they didn’t all
get detained
. Fortunately, Robofest made the news and one guard had seen it. They call Lara autonomous, but state that she can only move her limbs based on commands. Their reason for calling her autonomous is that she doesn’t need to be tethered to a computer to do this. Does that really qualify as autonomy?

This is whether or not the robot is operating independently or is merely tool that is being directly controlled by an outside intelligence.Since the actual signal to move the arms is coming from an on-board computer (in response to an external stimulus) I would argue that it is acting autonomously. Yes, it’s primitive, but that doesn’t invalidate it.",

No. Low level control signals sent from a controller have nothing do to with autonomy, especially if the controller is just doing what it’s told.If your reasoning were even close to sensible, we would consider our cars autonomous because the engine computer is what is really telling the throttle to respond, our foot simply moves the throttle sensor (well, on drive-by-wire cars like VW’s) and the computer “decides” to give the car gas. that’s absurd reasoning.pauldy said it (harshly) best. knowing nothing else about these kids, insisting on calling it autonomous because it is wireless is basically them wanting to sound smarter by saying they made an autonomous robot. instead they sound like dropouts that don’t get it.-Taylor",

[Jeri] put together an absolutely massive Etch A Sketch for
The FatMan and Circuit Girl show
. She had removed the DLP chip from an HD rear projection TV and decided to repurpose the 52inch screen. The movement mechanism uses pulleys from screen doors with nylon lines. The two sets of lines are fed in a criss cross pattern so that the parallel lines move in the same direction. The lines move tent poles in the x and y which controls the movements of the golf tee stylus. It’s driven by two high torque motors from $9 Harbor Freight 18V drills. They tried several different powders, but ended up using aluminum powder from an original Etch A Sketch because it sticks to everything. It will eventually be hooked up for IRC bot control once they get a large enough h-bridge.

[Bryan] sent in this cool
doorbell he made out of an antique phone
. After seeing similar phones for $150 to $399, he picked one up on ebay for $10. After some cleaning and polishing, it was looking fantastic, but fairly useless. At this point, he broke it open and started hacking to turn it into a wireless doorbell. He picked up a cheap wireless doorbell and proceeded to gut it. The transmitter side got an aesthetic overhaul, a big fancy button and nice LED in a 50’s style were added. The receiver side got hacked up as well. It was incapable of pushing the required voltage to ring the phone’s bell, so he had to do some searching for a better circuit. Since his knowledge of electronics was limited, he was looking for something that could be plugged in and work without much modification. Eventually, he found the
Silvercom AG1170-s5
. At $7, he swiped it up quick. It may be a bit of overkill, but he’s using an arduino to trigger the whole thing when it receives the signal. You can download the Arduino sketch on the site.

"content": "I like basic concept a lot. However, the specific implementation really is overkill.Someone suggested using the doorbell receiver to fire a relay, and use the relay to control a larger power supply to drive the bells. This makes more sense than the author’s design, but is not without complications. Ringer voltages run around 80 volts at 20 hertz. You probably aren’t going to find a power supply like that just lying around.i think I have a far easier solution: start with a small DC motor, ripped out of a toy or from the tray-eject mechanism of a CDROM drive. Using a few pieces of hobby brass and an RC airplane bushing, fashion a small crank, and attach the crank to the motor shaft. Remove the phone’s ringer coils, and install the motor so that the spinning crank can be linked to the armature with a music-wire pushrod or a small spring. The rotary motion of the motor is converted to reciprocating motion to drive the armature back and forth, thereby ringing the bells.an even better way is to eliminate the armature and clapper as well. Mount the motor so that the crank spins in between the bells. The crank arm should short enough that it just misses the bells as it rotates. Then, on the crank’s “handle,” you install a washer. The hole in the washer should be significantly larger than the diameter of the crank handle, so that it can move or “rattle” about. As the crank spins, centrifugal force drives the washer to the greatest radius. The washer will eventually strike one of the bells, and skip off. Because the washer is loose on the crank handle, it yields, allowing the crank to continue rotating. This is far easier to actually do than to explain in a text box.Interfacing a small DC motor to the door bell receiver would probably require nothing more than a single transistor and a resistor or two. No AC, no high voltages necessary. this mod is non-destructive. If you keep the parts you removed from the phone in a plastic bag, you can always restore the phone to original condition later, if you want to.",

Now that things have calmed down a little, here’s my two bits.@ac7zlA mechanical ringer is a good idea, one I also considered and mentioned in the project page. I went the more complicated route because I wanted to try something new. As far as making changes to the phone that are easily reversible, all I have to do with mine is unplug the external electronics box it’s connected to, plug it into a standard phone outlet, and I’m ready to use it as a normal phone.@josh maloneI agree, a hardcore audiophile would slap my wrist for mounting a vibrating device next to a turntable. Luckily for me my doorbell doesn’t ring very often, and when it does my turntable isn’t usually on. Even if the phone was mounted elsewhere it would still interfere with the sound from the stereo, except it would be from the sound of the ringer and not the vibration shaking the needle on the vinyl.@everyone with a positive commentThank you, I’m glad you liked my project. I really do appreciate it.@everyone who feels Arduinos are overplayed and are whoring up Make and Hack a Day, or that they’re for just for n00bs, or that the project is useless:Sure Arduinos are overplayed, much like anything else that becomes popular. They’re popular for a reason. If they were useless junk no one would use them. Arduinos are aimed at people who are just starting out with microcontrollers and electronics, or those who don’t care to get into details and just want to be able to create. Let’s not forget that all of us started out at as newbies in every subject we know, and it doesn’t make sense to make fun of those who are lower on the totem pole than us. Also, there will always be someone higher than us on the totem pole, no matter how much we know.I agree the project is useless, but it was a fun learning experience and a nerdy creative outlet. Maybe it will inspire someone else or help them with one of their projects, maybe it won’t. Who cares? I’m going to go drink a beer and enjoy life.",

"content": "At the risk of being repetitive, I’m going to call arduino abuse again. I just don’t see why it’s necessary to use a microcontroller to simulate a switch or a relay. It isn’t even the easy or lazy way out, it’s just the mentality of ‘might as well throw it in, since its here’.I think I could probably root around in the scrap box a bit and come up with something electromechanical that would work. Actually a lot of the parts needed are already part of the phone, so if you’ve got another to scrap. I’m assuming that the beauty of this is that the phone actually uses the original ringer and produces the original sound, so you aren’t wanting to just rebuild the ringer for low voltage. As has been mentioned before, the ringer signal from the phone line is low frequency AC. I seem to recall something about it being rated as 45 volts at 20 or 30 hertz, and the ringer coils are incredibly fine wire with thousands and thousands of turns, so they don’t draw a lot of juice. So I take an old low voltage relay, say 12 volts or so, with a pair of DPDT contacts, and wire the first set of contacts to act as a buzzer. This one goes to your fancy steampunkified brass doorbell button. Rivet a lump of lead to the relay’s contact arm to drop the frequency to a low buzz. Exact rate isn’t too important, just something lower than your typical AC hum. Wire the second set of contacts to chop the 12 volt DC into 12 volt AC and feed that into a transformer to step it up. One of the step down ones used to run doorbell buzzers should work. They’re 10 to 1, so wire it in reverse to step your chopped 12 volts up to 120 (or so. It’s not going to be very efficient at the low frequency and with your home made square wave AC) A few details like a capacitor across the contacts so they don’t arc, and another across the output to smooth things up a bit, and feed it into the ringer. Run the whole thing off of some dry cells, or the DC power source of your choice.K.",

Got an IBM PCjr laying around? Why not turn it into a
twitter browsing machine
? [Alex Grant] did this for the Rochester Institute of Technology’s Creativity and Innovation festival. You can enter search terms into the Twittjr and it will display the top 3 results from twitter. Leave it alone for a minute and it will refresh on its own. To make this happen, the Twittjr is connecting to another computer that is utilizing the twitter API to make the searches. The results are then pushed back to the Twittjr for display. All of this is done via the original modem. While [Alex] takes a moment to explain what twitter is, we feel it might be better to explain what a modem is. You see, back when the PCjr was new, we really did communicate via an analog signal over the phone lines at roughly 300 baud.
[thanks Chris]

D-Link Adds Captcha To Routers

D-Link is
adding captcha support
to its line of home routers. While
default password lists
have been abundant for many years, it was only recently that we started seeing the them implemented in malware. Last year, zlob variants started
logging into routers and changing their DNS settings
. It’s an interesting situation since the people who need the captcha feature are the ones who will never see it, since they won’t log in to change the default password.

This would also increase security even when the user just plugs and plays the router, since no one else can get into it, unless they get physical access to that router, or compromise its password some other way.",

The solution is very simple: have a machine at the factory generate two random alphanumeric strings, print them on a label on the bottom of the device, and program one as the WPA key and the other as the config page password. The user never needs to care about security; they just read the number off the bottom and type it into their wifi manager. Also, what [bertoelcon] said is incorrect. There are plenty of ways to securely generate random numbers on a computer. As long as the attacker doesn’t have access to the machine at the factory that generated the keys, there is no way for them to guess someone’s password, even if they looked at the keys off a hundred other similar routers.",

[Avi Aisenberg] sent us his final project for ece 4760.
His team built and OBD-II data interface
. Even though OBD-II is an industry standard, each manufacturer has implemented it differently. This is where this project shines. They have built it to be capable of talking to any of them. Not only that, but it has a nice backlit LCD screen for diagnosing issues without having to go back to your computer and downloading the data. If you really don’t need all the bells and whistles, you can
make one for roughly $15
. They even have an
OBD-II app for the iPhone

The
Irregular Incurve
is a robotic instrument built by [Xiaoyang Feng] as part of his
ITP
thesis work. It’s a MIDI instrument with an array of 12 strung bows mounted to a curved shower rod. The end of each bow has a tuning key. The strings are each picked using independently mounted arms. One servo controls the downward motion of the pick while the other controls the rotation of the shaft. A damper is also attached to each arm. The string vibrations are transferred to a spruce soundbox under the bridge. Below you can see a video of
Gizmodo playing with it
at the ITP show. Check out [Xiaoyang]’s
Flickr set
for images of the build process plus some early videos of the mechanism.

[Wolf] built this
LED Enterprise model
. It’s a ‘
sparebot
‘ assembled from leftover LEDs and resistors. Unlike most sparebot sculptural oddities, this one actually works. If you place it near a magnet, a reed switch closes to turn on the LEDs. A mechanical switch would have just caused more stress on the model. The part count is very low, but took some forethought. Two resistors are used to raise the resistance of the red LEDs to match the white LED. A quite clever and simple model.

[Zach] sent us a link to his
keyboard pants
. Frankly, we were astonished, not only by his craftsmanship, but by the fact that we were working on a pair ourselves. Admittedly his are much better looking and ours will probably never be finished. The inspiration for both his and ours, was
this sloppy version
. [Zach’s] pair have been cut in half, and he never really found a convenient way to reconnect the two halves, so only the left works. Watch this
video to see him playing some Tetris
in his awesome shorts.

Mud Tub: A Tactile Computer Interface

[Tom Gerhardt] has made this very interesting
mud interface for a computer
. Follow the link to see a video of it in action. It appears as though he’s using a laser grid of some kind to establish elevation. We might be way off on that though, there aren’t any details on the construction. He does mention that it is an open source hardware and software project, so maybe the details are available on request. In the video you can see it running as a projection surface where people are interacting with items directly on the mud. You can also see it being used as an external input device. People play Tetris using it in that example.
UPDATE:
[Moon] reports from the ITP show that the tub has a 16×12 grid of generic pressurs sensors on the bottom. These feed into a MacBook Pro which is projecting on the surface. Despite the sparse grid, [Tom] says he gets good resolution by interpolating between sensors; it can detect a resting hand pivoting on the surface.

We would be thrilled to get something like this in the mail. What you are looking at is the inside of
probably the coolest invitation ever to be mailed
. This LED array was enclosed in a mirrored box so all you could see were the lit LEDs. This was then inserted into a hole all the way through a catalog. You’ll have to see the pictures on their site to get the full effect. Only 40 of these were sent out, so we probably won’t get a chance to play with one ourselves. They mentioned that the first prototype was soldered by hand, just to make sure everything worked.

[Matthew] sent us his group’s final project, where they built a
nice GPS logging system
. Not only can it simply log the GPS coordinates on a predetermined interval, it can also be triggered to make an entry by a wireless device. In this example, they use a camera. This allows them to then upload all the GPS information and pictures to places like Google Earth.
They are using an ATmega644, with an LCD, SD card, and GPS unit. They had to do a little hacking on their camera to add the wireless transmitter, which triggers the logger. You can see not only the cost break down and source code for the project, but also a map with lots of geotagged photos. This is the kind of thing we can almost see as a standard item in the future.

[dunk] sent his
home made Radio Control system
. It is constructed from a Playstation 2 controller, an Atmega 2561, microcontroller, some RF modules and various servos and motors. It seems to work pretty well. You can get all the schematics and source code on his site. Several people have submitted a similar project which involves an
iPhone and a helicopter
, but that one is a bit dubious, mainly due to it’s lack of detail.

Nove Bit: A 9 Bit Memory Recorder
|
Caleb Kraft
|
[
"News"
] |
[] |
Nove Bit looks like a pretty cool toy
. You press sequences into the 9 buttons and it plays them back. We think it would be cool to play with. The artist [Nick Hardeman] states that the project is to allow you to save memories in 9 bit configuration instead of the traditional 8 bit computer method. Why don’t artists just say they did it because it looks cool? We want one of these, but We really think that recording our memories has nothing to do with it. You can see a video of it working after the break.

Remember
El-E, the service robot that would retrieve things that you spotted with a laser
? The creators of El-E are doing research into other methods of making assistance robots.
Their latest contraption is an iRobot Create, basically a Roomba, with a custom grasping hand
. Instead of complex multi DOF assemblies, they have made something that works on the same principle as a dustpan. It has a thin wedge and a sweeping arm that loads items onto it. As you can see in the video, it is quite effective.

Fart Intensity Detector

"final project"
] |
When we ran the story about the
office chair that twittered your flatulent activity
, many people commented on the fact that it had no method of determining intensity. Well, here’s the solution to that problem(is this really a problem?). These students built a
fart intensity detector
for their final project in ece 476. It measures the sound and temperature, as well as the composition of each fart. They really added some bells and whistles on this project. Not only will it display your statistics on and LCD screen after a reading, it will beep and, if your fart was intense enough, blow it away with a little fan. You even have the option of playing back the audio recording of your most recent glory.

NOR_/D has just released their newest
multitouch
display system. The
TouchKit Spark
features a larger 35.4x23inch display surface than its predecessor, the Run. It uses ultrabright IR LEDs around the screen’s border for
FTIR
multitouch sensing. A high frame per second IR camera is included to increase tracking performance. The screen is fully assembled, but you need to provide your own projector and case. It can be built at table height or as low as 20inches. The device is designed to work with
OpenFrameworks
, but future software releases will have
TUIO
support.

We posted a story about someone doing some
APRS tracking recently
. This is old news to some, but new fresh stuff for others. If you want to build your own tracker,
here’s a great writeup on one
. The WhereAVR is low cost, low power and has plenty of I/O. With all of the schematics and PCB files available on his site, you should be able to get one working in quickly. He does need a little help building a nice simple configuration tool to work in windows, anyone want to volunteer?

Host of the
Soldersmoke
podcast, [Bill Meara], contributed this guest post.
WSPR is a new communications protocol written by radio amateur and Nobel Prize winner [Joe Taylor]. Like the very slow
QRSS system described in a previous post
, WSPR (Weak Signal Propagation Reporter) trades speed for bandwidth and allows for the reception of signals that are far below the level of radio noise. WSPR takes “low and slow” communications several important steps ahead, featuring strong error correction, high reliability, and (and this is really fun part) the automatic uploading (via the net) of reception reports — [Taylor]’s WSPR web page constantly gathers reports and produces near real-time Google maps of showing who is hearing who. The WSPR mode is very hack-able: [Bill Meara] is
running a 20 milliwatt homebrew transmitter
from Rome, Italy that features an audio amplifier from a defunct computer speaker pictured below. This contraption recently crossed the Atlantic and was picked up by the Princeton, New Jersey receiving station of WSPR’s esteemed creator, [Joe Taylor].

Ever wanted to make your own LED? You might be tempted to after reading
how easy it is
. No, this won’t really be a practical LED that you would use to light a project, but it is very cool anyway. [Michael] picked up a box of Moissanite, or Silicon Carbide, on eBay for roughly $1. Making the LED is as easy as putting your positive lead to the crystal and touching it with a sewing needle attached to a negative lead. He has tips on how to get the best results as well as a little bit of history of LEDs on the site.
[thanks Andreas]

We’ve become far too dependent on “black-box” thinking. I’ve actually constructed a functioning vacuum tube out of a canning jar based on some plans I found through Lindsay Publications. Not for any practical reason, but because it was a challenge that our grandfathers took on. You simply never know when being able to “MacGuiver” something from absolute scratch might come in handy.",

[Tom] sent us a link to this very professionally done project.
He built a bike light that is a 540 lumen Luxeon
light with a custom case. The LED, Lens, and driver were purchased first. Everything else was designed around it. The design is compact and good looking. You can download the CAD files on the site if you want to make your own. He is using an Atmel AVR ATTiny13 to control brightness.

The CAD files are a nice touch too, more people should really include them – most serious hackers nowadays have our own machines or at least access to them by this point.Just a note to the inevitable clueless apologists for crappy hacks who keep pointing out ‘hacks aren’t supposed to be as good as commercial products, that’s the point’, well suck on this. Crappy hacks are NOT the point, you just aren’t trying hard enough or just aren’t good enough. Try following examples like this guy’s light. He’s got it right.",

Really makes me wish I’d taken some machining courses (and had space and money to buy such nice tooling :P).He should be able to get standby power consumption much lower than 7mA though. The BuckPuck draws < 0.5mA Iq, and in power down mode the tiny13 can draw as little as 0.5uA.Wouldn’t be too hard to do the buck converter with the tiny13 itself, a current shunt, and a low Rdson FET, and more importantly more space efficient. He’d also lose the 0.5mA Iq of the BuckPuck and with appropriate choice of 5V regulator could make standby draw less than the battery’s self-discharge.Nonetheless this is a great project and it seems like he accomplished his goals in a very nice looking package. Big props to this, most of us are just way too lazy to spend this kind of time on doing things ‘right’.",

I don’t know how LEDdynamics comes up with 0.5ma!I recently got a wireless bike computer and even though the bike light is inside a metal cylinder (I’ve even added copper foil under the vinyl cap) it’s so darn noisy that it interferes with the wireless wheel sensor. I may end up making my own buck converter after all.If I can come up with a way to do a video, I’ll post it on the site.",

PSP 3000 Firmware 5.03 Hacked

PSP firmware 5.03 has been hacked
by Team Typhoon. This allows you to run custom code on the PSP by taking advantage of the tiff exploit. You’ll have to wait to download the hack though, they haven’t released it yet. This means those of you still on
5.02
or still using the
little blue tool
will be able to upgrade soon.

From what I know homebrew is its own type so anything homebrew will work. All emulators work and homebrew games do.

[Daniel] had to have
runaway
in his mind when he built this
coil gun
. It’s hand held, holds 14 42 gram rounds and can propel them at speeds of 110km/h. Of course when it is battery powered, you have a 90 second warm up time between shots. It can also be used while plugged into a wall socket, which reduces the charge time to roughly 3 seconds. Great job [Daniel].

But if you’ve ever hooked a cap up to a scope with a square wave input, you’ll get a sawtooth output, because of the time it takes to charge and discharge the capacitors. Plus, with most coilguns, you need high voltage, so the battery voltage is probably boosted through cap switching or the like.",

I look forward to finally seeing whatever documentation you have on it (once the deluge ebbs and your site is again accessible)@lucas: just a guess (since I haven’t seen the schematic yet), but the light bulb might be a charge indicator (less likely) or being used as a form of variable resistor: originally Wein bridge oscillators used light bulbs in a similar fashion.@everyone rabbiting on about guns: first point, know what your kids are doing on the internet. Second, if your child has the technical know-how to build one of these, bravo; if they learn what they need to know to build one, bravo; if they build one of these fairly labor- and parts-intensive projects without you knowing, you have other problems. Third, of all the myriad of things I wouldn’t want a child to see from this site, this is fairly low on my list. This will foster knowledge of projectiles, magnetics, and working within design constraints. Other, still fascinating, hacks on this site (e.g. reprogramming electronic construction signs) have little in the way of educational value to a kid, and are far easier to do. Further, the “gun” is a standard footprint, and portability places interesting design challenges on the system.@designer: did you try different projectile weights? It may be that you can get more kinetic energy overall: Given E_k = 0.5*m*v^2, reducing mass to increase velocity gives a better energy trade-off.",

It would increase the speed of the projectiles, plus you wouldn’t need as large of a charge to move them.",

[Windell] from Evil Mad Scientist Laboratories took one of their Peggy 2 kits and gave it a little upgrade. The Peggy 2 is a programmable 25×25 LED display. It’s Arduino compatible and can accommodate big 10mm LEDs. Most people assemble them using just one color, but [Windell] decided to
create giant RGB pixels
by placing discrete red, green, blue, and white LEDs next to each other in the board. This creates a 12.5×12.5 grid of full color pixels. It’s an interesting effect and you should definitely check out the video embedded below which shows how the transition can be smoothed using a diffuser.

Here’s a pretty cool project done with the Lego NXT system. It’s a
robot that will draw you a picture
. Yes, we know it could be done
cnc style
, but this is much more fun. You load a picture into the software, adjust the levels so the software can create the vector version more easily, then let it rip. Now they need to
add face recognition
.
