Tank Drone With Automatic Targeting And Tracking

Humankind is making some great advances toward our own destruction with this
tank drone
. It’s got a powerful set of treads with an Airsoft rifle perched atop. Thanks to the cameras and the laser this thing can accurately target based on color. The hardware is controlled by a collection of Arduino boards connected via XBee so that Processing can be used on a computer. Just combine this with the
facial recognition from yesterday
and you’ve got the first generation of Terminators. Watch the clip after the break and you’ll realize that we’re doomed.

Sonoluminescence

Sonoluminescence is one of those strange phenomenon that many would never encounter outside an academic environment. For those who have never heard of it,
Sonoluminescence
is when tiny bubbles suspended in a liquid emit light while being vibrated at certain frequencies. We were pleased to see that
some plans are out there on how to build your own device to produce it
.

The pressure at a fixed point swings from low to high and back as the sound wave sweeps by. If the sound is loud enough and at the right frequency, the pressure at the trough of the wave will be so low that the fluid will boil, producing microscopic bubbles. When the high pressure front at the crest of the sound wave slams into these bubbles, they implode, and shock waves focus the energy of the implosion to a central region of atomic dimensions. The temperature at that central point skyrockets above 10,000 degrees Celsius, the pressure zooms to 10,000 atmospheres and a flash of light emerges for just a few picoseconds. The bigger the bubble, the more energy in the implosion, and the hotter and brighter the sonoluminescent flash.Fromhttp://www.scientificamerican.com/article.cfm?id=sonic-fusion",

[Dale Dougherty] interviews [Steven Levy]
about the history of hacking. [Levy]’s book
Hackers
has been released in a 25th anniversary edition. The interview alone is fascinating and the book is a must read for any hacker. If they offered a course in hacker culture somewhere, we’re positive that this book would be the textbook. The 25th anniversary edition has been updated to include major figures from the last 25 years including [Bill Gates], [Steve Wozniak] and others that have impacted our lives drastically.

[Yosh] came through with a link to
the Snake playing LED matrix
that he read about in
our links post from yesterday
. It seems that [Arty Fart] actually built three of these in green, yellow, and red. You can see him throw one together (an 8-10 hour job) in the video after the break. In addition to playing Snake the PIC 16F877A can also scroll messages, play a mean game of Tetris, and show a Pong screen saver on the 144 LED display. We love the clean build and the urge to make
another LED matrix
is becoming irresistible.
Now off to eBay for a good deal on a bulk LED order.

The term screen saver has been expanded to mean a non-interactive scripted sequence that is displayed on a screen.Screen saver is a lot easier to say.

Here’s a
Direct-to-Garment device that uses a stock printer
. [Jeff German] used an Epson R1900 with the stock firmware to get the results seen in the video. His hardware modifications involve adding two buttons to the printer’s circuit board. For DTG beginners this certainly lowers some of the obstacles to getting started. [Jeff] is working on detailed instructions but for now take a look at our own
How-to for building a DTG printer
.

Audible Tuner For The Blind

[Lain Sharp] modified this
guitar tuner so it can be used by his blind friend
. In the picture above you can make out a small white project box that houses the additional electronics. Inside is another battery and an ATmega168 providing a connection for an earphone. The AVR chip connects to each LED on the tuner and converts the visual tuning meter to an audio cue. Check out the demonstration clip after the break to see how it works.
Now if we could just figure out how to get our
strings in tune with our built-in keyboard

"content": "It may be true that blind people have better hearing capabilities, but for tuning an instrument without any help, you’d need to be able to hear what is called perfect pitch, i.e. you’d know yourself that your E string is off by 50 cent because you just know how an E sounds.Musicians, and probably also the blind, are more capable of hearing tonal differences, but perfect pitch is a very rare capability. So, well-trained musicians (and probably blind) can tune with a tuning fork very accurately, but without a reference tone, you can only tune your instrument’s strings relative to each other, but not absolutely.Also note that there are many situations where tuning with tuning forks or other audible reference tones is inconvenient or impossible, e.g. while on stage or in other loud environments or when the sound your instrument produces should not be audible for others (like when playing live and re-tuning between songs).Just like I tune with my amp on mute, this device allows a blind person to tune with an earbud. This is really a great hack!I also like the way the feedback is implemented with faster/slower beeps and high/low tones. Reminds me of “strobe” tuners…",

I can tune with a tuning fork or pitch pipe alone in my room but if I go out of tune onstage with my band it’s difficult to get back in tune. Part of the problem is crowd noise & the other part is my bandmates continuing to talk into mics or doodling around on their instruments. If they go out of tune onstage they have either an onboard tuner on their guitar or can clamp 1 on the headstock & see the led display to get in tune quickly. Being blind, this doesn’t help me a bit, so everyone else has to shut up long enough for me to hear my guitar while I tune. Add to this the pressure of getting in tune fast so we can start the next song & it gets stressful. Plus, it takes time away from drinking a beer in between songs! lol",

Straight out of Ghost in the Shell, the Laughing Man makes his appearance in these
security camera shots
. [William Riggins] wrote us to let us know about his teams
Famicam scripts
. After taking a screen shot, faces are detected and counted, ‘anonymized’, and the final image is uploaded to
Twitter
.
The process is rather simple, and sure beats wearing a bunch of
white reflective camouflage
. All that’s left is detecting
specific
faces to make anonymous, and of course uploading the script to every camera in the world. Easy, right?

Precision CRT manufacture
Here’s a great video from Tektronix about
building a precision cathode ray tube
. The tube manufacture method was developed to use in oscilloscopes and we’d guess it dates back to the early 1960’s. [Thanks Bill]
Snake on an LED matrix
We would have done a full post o this beautifully built LED matrix but we just couldn’t find much information on it. For now,
enjoy the video
of the device playing the classic game of Snake. [Thanks Xdr]
Wire bundling
We’re not sure if this is brilliant or just snake oil. Here’s
a method of bundling wires together
by twisting them with an electric drill. We’ve always just used our hands but we’ve never really worked in any kind of volume either. [Thanks Kacper]

Let’s compare notes on what’s worked or not.My most used variant of wire twisting uses a VSR drill that has a “speed setting knob” on it’s trigger. Drill gets clamped to table and drill power is controlled with a foot switch. which gives me both control and an inherently “Less Unsafe” condition. As that foot switch keeps the operator’s hands a bit further from the wire path while allowing for some single operator uses.",

Just three equally spaced holes: Cat5 connected to the outer two and the drill to the center one using threaded rod and a couple of nuts. This gave a gentler twist.

I cut two lengths of wire (longer that I need as someone already mentioned,twisting makes them shorter) anchor the “free” end to something that won’t move, make sure the two wires are not already twisted, insert the other end into the drill, pull tight and pull the trigger. If you do it right you will get a very uniform twist the whole length of the wire, which is important when creating impedance critical twisted pair.

The use of the wood beam had two goals. It didn’t really decrease the shortening effect by as much as you’d hope but what it does do is increase the angle of twist which decreased the number of turns required to keep the twist in place, which should mean less stress placed on the wire cores.",

It helps a lot with test leads, even on power supplies but particularly on high-impedance signals, like when you’re trying to measure the voltage in the middle of a resistive divider that drives the feedback to an amplifier. I’ve found it’s best to twist the wires until they’ve shortened about 10%, then stop the drill and give a brief light pull to set the twist, so they won’t spin or kink when you undo the drill.Note that twisting them together works great, but if you want them to be reusable (as in not stuck twisted) if you rotate each wire individually they will coil around each other naturally, without taking a set.

[Oliver Nash] was enlisted by his parents to
fix their robotic lawn mower
. They owned a
Robomow
which happily navigated their yard to keep the grass at a nice level. These robots rely on a perimeter wire with a special signal running through it to ensure they are inside of the mowing area. Confronted by a dead perimeter module, [Oliver] ordered a new unit and disassembled the old module to study the components. He also measured the signal generated by the replacement unit. In the end he was able to produce a replica of the signal using audio software, burn it to a CD, and playback the recording using the perimeter wire. It’s a bit of a zany idea but it worked.

This is definitely an odd way to reproduce the signal, +1 for creativity. If you really wanted to reproduce the signal with another circuit, shaving off the diagnositics (continuity check and such) would make this circuit painfully simple and it could easily be put together on .100” perf board.This guy is definitely zany.",

Building a circuit to generate the signal out of discrete components (as Jake suggests) would be *cool* but tough and maybe not worth doing till the easier solutions were working reliably first.One final comment might be that the perimeter switch that Friendly Robotics sells is a bit of a rip off. It cost almost 100 euros. If someone worked out the simplest possible circuit, I’d say it could be built for about 5 euros. Dunno how big the market is but it’s a thought!@Jake: you’re right and I would certainly have liked to fix the original board but it wasn’t easy working with that conformal coating. I did a little reading and from what I could tell the coating I had was not so easy to get off relative to some other types (e.g., I wasn’t dealing with silicone based).@Jason Garland: I’d love to know how similar the system that the LawnBott uses is. If you have a ‘scope you should hook up its signal generator and let us know what you see!@WapiFlapi: That’s awesome, it’s years since I saw that film but I like that the idea cropped up there too.@Pff: I think you’re being a little less charitable here. It seems to me that my results are misrepresented if you simply say that my signal didn’t work. I did succeed in getting Robomow to get cutting albeit unreliably.",

In fact I briefly mention that I did try this (in last paragraph before “A final thought”) but the mower still complained. This perhaps implicates my cheap LM386 amplifier or maybe indicates that sampling at 44.1KHz is not quite enough.Also, though I tried both with the generated and the recorded signal, I preferred using the generated signal since I wanted to know which aspects of the signal mattered.Regarding listening for odd breaks, this is another good point. I think it might be hard to hear them if they’re fast but this possibility was the reason I carried out fairly extensive digital testing on a portion of the signal significantly longer (~50 seconds) than the typical start time of the mower (<20 seconds). I found no divergence from periodicity other than what I mention in the post so I'm pretty confident I haven't missed this.Thanks for sharing your thoughts!",

"content": "days later…Many hard conformal coatings can be boiled off, with a slight risk of water impregnation in cheaper fiberglass pcbs. In addition, almost all conformal coatings can be removed by one of three or four solvents – including more conformal coating.You can play amateur chemist as follows: obtain a half dozen test tubes, or just make some squares of filter paper or fine mesh screen.Next, scrape off a bit of coating and divide it into batches. Big flakes if you can do it. Then put a batch in each test tube or on each square.Add a few drops of Alcohol to one, Acetone to another, and perhaps kerosene to a third, and so forth. Nail polish remover, vodka, fermented ferret urine… the possibilities are endless.Ask a chemistry teacher or google for the names of common solvents. All of them will be available at almost any hardware store. One of them will likely disolve or soften the coating sample.If one of your materials softens the coating, you can paint it on, wait a bit, then hit it with a toothbrush.When all done, run the board through a dishwasher and the dry cycle. Use calgon or some other spot removing agent to ensure a clean board.Some coatings respond to high heat, like from a hair dryer. Some don’t and will bake on. Therefore, test a little. It doesn’t take much to build up some expertise in reverse engineering.Lastly, to the “It’s a rip-off, just $5 of parts in the circuit.” guy…I’ll bet you know a lot of people who are totally and astoundingly ignorant about electronics in general. They’re everywhere!You know the kind: They wouldn’t know a resistor from a capacitor, and to them all of electronics is divided into needs batteries and needs AC from the wall.The thing is, you may not realize that you know about as much about business as they know about electronics. 5 euro worth of parts, indeed.That’s like saying you can create a hot super model with an IQ of 135 by combining a sperm and an egg.

This
portable Atari
is the result of [Mario’s] toils. The core system is an Atari Flashback 2, an embedded system released in 2005 with several built-in games. The stock titles weren’t enough so [Mario] added a cartridge slot in order to play whichever games he wishes. The case was originally the packaging for an iPod touch so you know it’s sturdy. We also like the free-formed audio amplifier as seen in the
work log
. Does anyone know if the Flashback 2 has
a pause feature
?

After a gruesome accident involving a harvester, [Oscar] lost his legs. [Noel Fitzpatrick] a mad scientist veterinary surgeon came to the rescue. [Oscar] now has leg implants prosthetic feet. It is pretty amazing that a cat would even function in this manner. Have you ever seen one
try to walk with tape on its feet
? We have to wonder why that cat doesn’t have some more awesome looking legs though. We think that cat needs to team up with [
Aimee Mullens
], the olympic athlete with no legs, to get a
better looking pair
.

I recommend you try YouTube for your stupid cat video pleasure.@reality Finally, someone who gets it. We have plenty of American doctors who are doing this all the time. In fact, I bet there are more American doctors doing this than there are Vetenarians doing this. I am a veteran, and I am in a veteran hospital, and I see prosthetic legs here that Oscar wishes he had. Legs that can lift the user from a sitting position to a standing position. I see bionic knees here that can mimic the owners gait within ten steps. I see bionic shoes here. The doctors in this hospital are NOT getting millions of dollars a year here, these guys are doing it because it is a noble cause to repair veterans. We won’t even get into facial cosmetic advances done in this hospital. This is being done all over the United States.Since when did becoming a doctor become evil? And if you want to know why doctors get paid so much money to be a doctor, just take a look at what they have to do to become a doctor. First take a look at the cost of going to school. Most people can NOT afford to go to school, hence a government loan. Those have got to be repaid, and fairly quickly as the loan interest will quickly escalate until the loan can not be paid. Then you have the YEARS of indentured servatude that they have to complete. Think about being on a job 20 hours a day and getting paid a pittance for it. And don’t forget that the school loan has got to be paid, so part of your paycheck is going to pay that loan. When you get done, you have to pay outrageous amounts for malpractice insurance. Want to know why? Then on top of all that, taking Medicaid and Medicare payments which are not paying for the service rendered. Not going to get into the insurance thing, but it is enough to make you not want quit being a doctor. So between malpractice insurance, being frivolously sued, and not getting paid for your work, insurance practices, having to pay salaries for your secretaries and nurses, equipment costs, and the day to day operations, they are not going to be cheap.Now we have a major border invasion with people coming in to our emergency rooms and demanding care. Think they are going to pay for it? No, because they would not even take the time to become a citizen in the first place. I have zero, zip, nada, compassion for those people. Be lucky there is not a president like me. If I were president, I would send the military, and they would have loaded guns.Now, can we go back to how cool Oscar’s new paws are?",

[Taichi Inoue] is back again, this time with a
multitouch system that uses water as the touch surface
. The setup consists of a tank of water placed atop an LCD, a lamp, and a web cam. The web cam pics up the light that is reflected when something breaks the surface of the water. It is, as far as the computer is concerned, no different than the blob recognition we see with many of the
home made multitouch systems
. Mixed with
his Yukikaze
, this guy might end up with the most relaxing computer system in the world.

We love it when footage of a robot prompts a “holy crap” response from us.
This little guy
, a product of the Chiba Institute of Technology, uses four rods as a suspension system for jumping. The bulk of the bot can be moved up or down, using its momentum to raise the wheels and jump to the next level. Check out the clip after the break to see how getting down involves a controlled fall as graceful as a dancer. Doctor Light better get cracking on
another robot
to take this one out when it turns on us.

Multi Multimeter Clock

[Alan Parekh]
built this clock to look like a Multimeter
using analog multimeters for the three displays. A PIC does the timekeeping and feeds a specific amperage to the three displays which show hours, minutes, and seconds.
We’ve seen
clocks that use analog meters
before. [Alan] took the concept to the next level, replacing the graduated markings behind each needle to correspond to the correct display. He’s also included precise calibration so that each meter is as accurate as possible. After watching his video we’re convinced this is a refined product ready for a wide market, at least for those who appreciate the geek factor of the display.

And it’s a clock that can actually be, you know, read by normal people without a Calculus degree.The batteries are only there for timekeeping when outside power is unavailable. The meters aren’t ever driven from the batteries, as the PIC is programmed to go into low-power mode when this happens. This thing should last years on a few AA batteries, since they’re just used to keep time when the power is out.The meters themselves are set to the lowest-current mode they have, 0.5mA full-scale.All good things.And I’d do it differently. In fact, I may:Scrap the giant air-filled housing, and the control boxes themselves. I’m thinking simple panel-mount ammeters, or just recovering them from cheap-ish multimeters.Switches instead of jumpers. I hate jumpers.I don’t like the way the needles bounce on big changes (reset to 0 seconds, for instance). Slowing down the input to the meters (low-pass? bell curve? something) or adding (predictive?) feedback would do a lot to help that.I don’t like the fact that it’s probably wildly inaccurate. I want a PPS input from a GPS clock, or maybe just a box running NTP. Or, at least: Use the AC line as a stable 60Hz reference, which is always almost exactly dead-on, just like electric clocks have done forever. (That it’d drift a bit in battery mode is OK.)",

Like many specialty plants, growing mushrooms requires that you keep a fine balance between humidity and temperature. this can be fairly tedious at times, so many opt for automated systems. [Anthony_p1234] has chosen to
build his own
. Using an Arduino, he controls power to two heating pads, a sonic humidifier, and an air pump to keep his mushrooms happy. He shares the process of building the system, testing and calibrating the parts and putting it all in use. We didn’t see any schematics, but he does describe everything fairly well. The source code is available for download.

Mr. Burns Prevents Sun Burns

[nmcclana] wrote out this very detailed instructible on building
Mr. Burns, a sun burn alarm
. Enter your skin type, sunscreen type, and UV levels for the day and Mr. Burns will let you know when it is time to go seek shelter or re-apply that sunscreen. Built on a Propeller platform, he’s using a blue LED as the UV sensor. He mentions that the device is fairly accurate, however people tend to put sunscreen on too thin and that will throw off the readings. There is a video of it in action on the instructible.

Fusion, In My Backyard?!

Here is
the 32nd amateur fusion reactor built in a basement. [Mark Suppes] is right behind
[Will Jack]
, the (then) 17 year old
[Thiago Olson]
,
and [Mileiux]
in engineering a homemade nuclear reactor. By taking two light elements and colliding them under extreme speed and pressure, a heavier element and energy are produced.
[Mark’s] goal is to lasso in investors to earn enough money to build a larger
Bussard Reactor
, which will hopefully produce as much energy as it consumes. Free energy at only a couple million dollars; who
wouldn’t
pass up this opportunity?
[Thanks Imp]

This fusion is so low powered that there will never be a chance of any danger, and the small amount of neutron radiation they produce is less than you get at cruising altitude in a plane.And no, there’s no chance a machine like this can generate net power.

The FBI released all the documents (no proof ofc) back to his home government. His mechanical resonator never existed (if he really caused earthquakes in Manhattan why was there no newspaper article?). He believed you could get free energy forever by electrolyzing water into H2 and O2, letting it rise and recombine into water, and turning a paddle wheel. He actually filed a patent on this late in life, apparently he hid it from everybody because he was afraid they’d use it, but thought he had nothing to lose when he was too old. Finally, despite the claims, his Tesla coils were actually far less efficient than modern-day versions. Note, however, that his purpose was transmitting ‘electrical vibrations’ through the ground instead of the air. He actually wrote Marconi and told him he had it all wrong. So, the ‘efficiency’ of his wasted energy is debatable.Also, be careful about internet mumbo-jumbo. It’s really holding you back from real knowledge. Vacuum energy is theoretically possible. It’s a real research project with real PHDs (and lowly underpaid grad students) and millions of dollars in funding. Now, having said that, it has nothing to do with vacuums or spinning disks or electrons or anything.Just be careful – the internet lets anybody talk with any kind of authority they can say they have.Seriously, I’m begging you… if half the people that believed all this stuff put their creative energy towards something useful the world would be a much better place.",

In theory, as the technology advances, we could keep reacting the waste products until they are about down to iron. The shorter half-lives of the next-generation reactors’ waste will make storage problems much smaller.So basically, the less we freak out about nuclear energy, the more efficient it can become, and the better chance we have of safely disposing of the waste we have already accumulated.",

Electrically speaking, it is still more efficient to use a wire for communication than radio based, too, though, that can cause logistical problems, such as environmental issues in the middle may cause that wire to break, blocking the communication. When you think about it, for communication, we put several watts (on HF, 100W is not uncommon) into the air, to pull a few microwatts out of the air at the reciever. If we were to do that by wire, we could easily get by with much less than a watt.",

"content": "@JJI really don’t want to step into what is becoming a fight amongst the tinfoil hat brigade, but your statements with regard to stirling (not “sterling”) motors betray a certain ignorance of the subject, despite you having “built” one.Like any heat engine, the efficiency of the stirling is proportional to the temperature differential applied to the motor. You are correct that those cute little stirlings that are claimed to run off the heat from a cup of coffee are no more than curiosities, and barely turn themselves. But that is true of *any* heat engine trying to operate from a poor-quality (low delta T) heat source.When stirlings are run on high-quality heat (high delta T) they are very efficient (I’ve seen claims of 40%). The best stirling motors are hermetically sealed and even pressurized. Motors of this type were used to great success in experimental postal fleet vehicles under a NASA study. These motors provided adequate power and torque, and as external-combustion engines, were capable of running on a wide variety of fuels. The downside? It is difficult to “throttle” a stirling motor.Of course, if the stirling is powering a generator to produce electricity, this is far less an issue. In fact, another study I read just a few years ago stated that if you compare a reflective parabolic dish with a stirling motor/generator at its focal point to a photovoltaic array of equal capture area, the stirling generator produces *much more* electricity, despite losses implicit in a mechanical system.No single energy production/conversion/usage technology is going to solve all of our problems. If there is one, it will likely be Bussard’s inertial electrostatic confinement fusion. Stirling motors will provide an excellent way for making productive use of the heat produced.Bottom line, there *will* be more stirling engines in your future.",

A couple companies are currently working on getting them mass produced for grid production (Stirling Energy Systems) and are test running a facility in the Mojave desert. If a market develops for a product, and the tech is proven, a company will take it up and develop it. It just hasn’t been economically feasible in the past. Those stirling engines have high maintenance costs. Yes solar is cheap, but until the California govt posted a contract to pay for the stirling engines if they could pass the proving stage (which its in now), they would never have been economical. It will cost more to generate a single watt from the stirling engines than it would from coal, at least thats the way the economics of it seems to be working. As economies of scale come into paly, who knows. But no startups would touch the engines for grid production cuz until ecological factors came into play, no govt would pay more money for the green source than for the coal source. Also keep in mind politicians like tried and true solutions (coal) since theres less risk and they can run better cahnce of reelection compared to more risky new techs (stirling).",

Keep it up! Not only does it drive them loony mad, but it amuses me greatly, thinking they are about to suffer an aneurysm because no one will believe them and take them seriously.@ Coke snorkin’, tinfoil hat wearing, hemp clothed, Marty Feldman eyed, stark raving mad, lunatic fringed morons, please note that those ideas you got when smoking weed, probably are not going to work. Unfortunately for you, and fortunately for me, the Internet gives you guys as much a forum as Stephen Hawkings. The difference of course being that Mr. Hawkings actually knows of what he talks about. The fun part about this is that when you guys get into a corner and talk and the air gets heavy with aromatic herbs of the mind altering types. Then one of you apparently writes this stuff down and puts it on the Internet, which the rest of you then take as gospel and inarguable. However, you must know this, something for nothing and your chicks for free, is only a song lyric. While I dig the rock music, I know that is not truth.Every bit of energy is accountable from something else, the law is immutable. Please take a look at Conservation of Energy, and Newton’s Three Laws. If you can understand them, then try and break them. Bring us a working demonstration model.

Working With The AT90USBKey

The
Genearic HID tool
is meant as an easy way to create your own human interface devices. The project has the added benefit of showing us how to
hack the hardware on the AT90USBKey developement board
. The AVR-based device, which we saw used to make
an SNES cartridge reader
, comes in at just over $30 but with a few caveats. First, the breakout pads for the pins are not 0.1″ pitch and require some creative soldering to get at them easily. But the walk through also covers converting the board to run at 5v when in USB host mode, and altering the populated components to reclaim pins on the AT90USB1287 chip. The fun isn’t limited to this board, there’s also
a home brew alternative
based around the same chip.
[Thanks Juan]

The ability to use AVR-GCC was what really pushed me over — I’ve moved away from Windows for *all* of my development, and booting up a Windows VM just for MPLab and PIC_C18 (which are… less than pleasant experiences compared to a GCC-driven workflow) was a pain that I was more than happy to eliminate. I haven’t checked out the Generic HID project (looks pretty nice, will be experimenting with it myself), but what I have found to be useful is the LUFA project (Lightweight USB Framework for AVR’s, found athttp://www.fourwalledcubicle.com/LUFA.php). It’s pretty awesome code (with excellent commenting to match), with a lot of different profiles (different HID’s and other device ID types, as well as a lot of host stacks); and it all works pretty well with the AT90USBKey’s bootloader. The weird headers used on the AT90USBKey do present a problem, but I ordered a bunch of matching connectors and it’s not a huge deal for me now. I do like what they did in the linked article; might try that myself.",

The chips come factory flashed with a boot-loader.You can’t beat the free no-restriction Win-AVR/AVR-Studio C/C++/ASM development/debug/simulate environment compared with anything similar from the likes of Microchip or TI. The one instruction per clock RISC architecture of the AVR line is as fast as it gets in terms of mainstream micro-controllers (e.g., ATTiny’s run at 20 MIPS). Mainstream PICs in comparison take four clocks per instruction.Finally, the $49 ATMEL AVR Dragon board is an incredibly powerful ISP/HVISP/JTAG programmer/debugger that is no longer target size limited.

"content": "Teensy does seem like a nice board, and is probably going to be what I order for the next board to put into a project — looks about as good as (if not better than, in some ways) the AT90USBKey, so I’m looking forward to a project that will justify ordering one.I was a PIC guy for probably about five years (learned a lot about them, and built a lot of projects with them), but certain quirks in the architectures always bothered me. The dsPIC/30/24 series all sounded pretty interesting to me, but after reading about the AVR’s, plus the advantage of the AVR-GCC toolchain, PLUS reading the code for LUFA (seriously, it’s like the Microchip USB sample projects on steroids), and finding the low cost AT90USBKey (didn’t know about the Teensy at the time), I figured it was as good a time as any to switch. I really couldn’t be happier; PIC got a lot of projects done for me, but AVR is *so* much more pleasant to work with. Also, I can’t speak to the one on the Teensy’s, but the AT90USBKey comes with a great, stable USB bootloader (much more usable than the one from Microchip for the PIC 18F’s, in my experience). I have heard that Teensy is similar in this regard, but I haven’t used it myself.As for the mating connectors, the ones that I found are from Major League Electronics (had never dealt with them before, but they have great customer service and were the *only* ones with a 1.27mm (0.05″) pin spacing, dual-row 2.54mm (0.1″) row spacing header design that I could find in small quantities). If my notes here are correct (they are :P, but you may want to take a look at the data sheets to make sure the options are how you want them; these are what I got and they’re working well enough), the part numbers are:TSHS-605-D-05-A-G-LF — This is a male header, straight pin, 2×5 (a match for the six ports). This is what I populated my AT90USBKey with — they’re quite snug, actually… a very tight fit. I did much of my early development (they arrived two days after the Key itself) with them loose-fitted in because a friend happened to ruin my good soldering tip.LSSHS-605-D-02-G-LF — This is the matching female header. Snug fit, some prototyping projects could easily hold onto the board well enough by aligning a few of these together, similar to a “shield” configuration — that’s how I’m designing some of my boards. This is a straight-leg part — you can get them bent for surface mount designs, but I don’t have that part number here with me.Working on a PCB design for “wings” similar to those in the linked article, based on these part numbers; would be very useful to have such an adapter, but the company who made them is no longer in existence on the ‘net, it looks like. I’ll post designs here, and maybe throw them on batchPCB or something so people can order a set easily on the cheap. Simple enough, should be able to whip out the right footprints in an hour sometime this weekend.",

"content": "I have been looking into making DIP adapter boards for AT90USB chips. I have also been looking at PIC 18F chips as they come in DIP format.I am more familiar with AVRs and they are more powerful due to hitting nearly 1 MIPS per MHz than PICs. As other have said the development environment is also a lot better than MPLAB. On the downside they are not available in DIP… I have hand made about 40 Retro Adapters which use ATmega168s in TQFP format and while not too hard to do it is certainly a lot slower going than DIP. You can’t just grab a bit of matrix board either.Cost wise they two are actually fairly similar. The AVR needs slightly more external hardware (resistors on the USB lines and one capacitor) and a PCB, the PIC costs more to start with.If I do go the PCB route I will sell them on at pretty much cost price with the AVR pre-soldered on and loaded with the standard Atmel bootloader (or perhaps the LUFA one).If anyone is interested post here or email me directly (mojo@world3.net) so I can gauge demand.",

We don’t know how we missed this when it first came out, but there is a hack out there that
combines a .22 caliber pistol with the video game Half-life
. Simple is best and that motto is in use here. A wall was built down range to use as a projection screen. Accelerometers mounted on the drywall report vibration data from the bullet strike which is used to triangulate its location. This targeting data is then sent to the game interface.
As you can see in the video after the break this works like a charm. The [Waterloo Labs] personnel that developed this are also responsible for
that iPhone controlled car
. The antics we witnessed in that project carry over to this one as they illustrate using the setup to play Half-life with a couple of shovels at 2:12 into the clip.

"content": "@nubie:3 sensors are required for triangulation (Hence the term “Tri”angulation). Using total field sensors (e.g. sensors that lack directionality) In 2 or 3 dimensions, 1 sensor will limit the search space to a circle for 2D, and a sphere for 3D. 2 sensors will limit the search space to 2 possible points (one real one imaginary) in 2D, and a circle in 3D. The 3rd sensor will give you a single point as the location of interest in 2D, and a search space of 2 possible points (one real, one imaginary) in 3D. A 4th sensor will give you a single location of interest in 3D, however this is generally not necessary (Depending on the application) as the imaginary point in 3D is often easily distinguished by constraints imposed on the search space.Most sensors however do report directionality (+/-), but are sensitive only along a single axis. Most “sensor packages” make up for this by including multiple single axis directional sensors arranged such that their sensitive axises are in an orthogonal configuration. So a 2 axis sensor package is not 1 sensor, it is actually 2 sensors aligned orthogonally.Using 2-axis sensor packages, you can then triangulate in 2D with 2 sensor packages (e.g. 4 sensors), assuming that the information you are sensing has components in more than one axis. This is because the gradient of the signal between the 2 sensor packages will tell you which of the 2 possible locations is real and which is imaginary. For 3D triangulation you still need a 3rd sensor package and the packages must be 3 axis sensor packages (Again the gradient of the field will eliminate the imaginary point for you).With that background information, now consider the situation at hand. Since they are using accelerometers on what we can consider to be a flat plane, the information they are sensing will be transverse wave deformation of the flat plane, which is measured orthogonal to the plane.The 2 axises lying in the plane will contain very small high frequency longitudinal wave signals that are unlikely to be above the noise floor of the sensors, which means that unless you plan on machining precision mounts and spending a great deal of time calibrating the system in order to put the transverse wave signal into more than one axis of a single multi-axis sensor package, you will need to use 3 single axis sensors at different locations in the plane. Also, the calibration for the complicated 2 sensor package multi-axis setup will be rendered void after a few shots as small semi-permanent angular deformations will translate into significant signal being moved from one axis to another. This would give you wrong and or impossible answers.",

To triangulate, you need a pair of 2-axis accelerometers. By measuring the X and Y magnitude in each accelerometer, you can calculate a direction vector. Two vectors originating from known positions yields the hit point.To further extend this project, use an impermeable backdrop instead of sheetrock or concrete board. Commercial installations use a flexible cloth impregnated with steel fibres. Solid steel could be used too, if angled to prevent ricochets.I see no reason why this couldn’t be done with a pair of piezos (with bulletproof shielding, of course) and a microcontroller with HID software. This doesn’t really lend itself to first person shooters, but there are plenty of arcade rail shooters this would be perfect for. And Duck Hunt.I volunteer to help create this. I’ve been looking for an excuse to get a gun, and this seems perfect. Contact me if you’re interested.",

We all love blinky lights. What we love even more than blinky lights is a very detailed tutorial with great photos. [Richard Kline] has written this fantastic tutorial on how to
build a large 5×7 LED matrix and control it with a PIC processor
. The bulk of the body is a foam insulation board, covered with a diffuser. Source code and schematics are available for download from the site. If you’ve ever thought about getting into PIC processors, this would be a great beginner project.

Selective Laser Sintering Rig On The Cheap

"selective laser sintering",
"sls"
] |
[Peter’s] been hard at work designing
an affordable Selective Laser Sintering (SLS) 3D printing platform
. We first saw his work on this back in April when he was
working mostly with acrylic
. Now he’s moved on to a design that relies on hardboard which has resulted in a build that comes it at around $20 including the motors.
The design uses a dual z-axis table for the feed stage and the build stage. That is to say, as the powder is fused together by the laser the platform it is on is lowered. Next to this platform, the feed platform is raised, allowing the power to be swept onto the build stage. This setup is moving in the right direction, but we’re still waiting to see what works when it comes to adding the laser and sourcing the powder.

"content": "random but pertinent fact i learned about lasers last week. I was talking to an optics guy with a PhD in Physics last week about the new wickedlasers 1W handheld blue laser, and also asking about military laser technologies, which use infrared. He mentioned that in many ways, the blue laser is more dangerous. This is because, being visible light, the eye has a tendency to automatically notice it, focus on it, and track it. That means that the eye will focus the beam in the most destructive way. He also mentioned that because of the way our foveal system works, your eye will keep darting around to gather the whole scene, and in the process it will keep moving that focused blue laser all around destroying everything in the process.The military uses infrared lasers because of their power and ability to penetrate the atmosphere, and the nice thing is that since your eye doesn’t focus on it, the interior of your eye stays relatively undamaged. It will burn the surface of your eye much like a sunburn, which is still bad but seems to be a lot better. You’re also more likely to turn away from that, whereas we have evolved to turn towards and focus on visible lights.So keep that in mind when lasering! I mostly bring that up, because my first thought was that the new blue laser would be great for this, until i realized that the reflected light would be way more dangerous than infrared!Its probably best to use an infrared laser coupled with a low power visible laser, though again that would draw your eye towards reflections. High powered lasers are just dangerous no matter how you use them!-Taylor",

With the advent of low cost 1W lasers, more people need to be made aware of the severe damage these things can cause, because even a reflection off a while wall can blind you! Some kid might buy one because its “cool”, but at these power levels, they’re insanely dangerous.Sadly, I expect that the 1W laser pointer will result in at least 20 dumb kids getting blinded or blinding others before some sort of regulation is put into effect.

"content": "Ok who ever said that a visable laser is more dangerous than an IR laser is plain wrong. You had to have misunderstood your optics friend. The danger of lasers can be related to exposer time and Lens transmisivity. UV lasers on one end of the spectrum will not transmit through your lens but will photo-ablate it (read about Lasik). Visable lasers (somewhat in the middle of the spectrum) are just that, visable, the first rule a laser guy will ever tell you in the safety brief is “if you see a flash in one eye, don’t try to see it again with the other eye”. Typically one would see the flash and turn away. Your body also has a natural blink response to these types of events (ever have a flash light fhashed in your face?). Thus minamizing exposure to a small limited area. IR lasers on the other hand are again invisable (like UV lasers) but even worse is the fact that the Lens of your eye not only will transmit the IR light but will focus it on your retina. And this is the worst part, since it’s invisable there will be NO BLINK response meaning, you won’t see a flash if your lucky you’ll notice your vision getting dimmer. Either way Perm damage without you noticing.",

SOAP Compatibility For SQLmap

[_coreDump] was doing some database vulnerability testing using SQLmap to automate the process. To his dismay, the package was unable to test using the Simple Object Access Protocol. Faced with having to manually test all of the SOAP vulnerabilities he decided to work some Python magic and add support.
His solution
allows SQLmap 0.8 to parses XML data from the SOAP protocol by modifying three files from the package. He’s made the diff files available if you need this functionality for your own security testing.

Adding Motion Control To An RC Transmitter

"gyroscope",

"rc",
"transmitter"

If your soldering skills are up to snuff you can
add a motion control feature to your radio controlled transmitter
. [Starlino] used a combination accelerometer and gyroscope module as an alternate source of analog control information. He built a filter to dial in the analog voltage range to match that of one of the sticks on the controller. A switch is used to disconnect the signal when motion input is not desired. This would be a nice addition to one of those
more creative aerial hacks
.

[Taichi Inoue] put together this beautiful visualization system called Yukikaze, japanese for “snow wind”. Basically a spectrum analyzer, Yukikaze is delightful to watch. We would love to see what kind of response he gets, as most of the footage shows very slowly changing smooth jazz. While we don’t think he gets crisp EQ visualizations out of this since it is a single large chamber, we still think it is amazing to watch.

Machining A Horizontal Stirling Engine

Satisfy your need to view some quality machining by looking through
this Stirling engine worklog
. We’ve seen these engines used a few other times in
creating electricity from solar energy
,
powering a car
, and even
built from aluminum cans
. [David Morrow] built this rendition to push the limits of his machining skills. We’d say he succeeded. The finished piece should run with the help of a heat source such as a candle. There’s no video of this engine, but we’ve embedded a clip of a similar device after the break in order to give you an idea of how this would work.

[Geordy]
added a serial port to his Zipit
. It uses a 3.5mm jack as the connector. He managed to include an RS232 level converter inside the case. Both components were hard to fit into the cramped quarters but he did it and he kept
the hacker-friendly device
looking nice too.

Unwrapping 360 Degree Video
|
Mike Szczys

"360",
"openframeworks",
"processing",
"video"
] |
[Golan Levin] found
a way to unwrap the 360 degree images
he created with his camera. He’s using a Sony Bloggie HD camera which comes with a 360 degree attachment for the lens. This produces a donut shaped image (seen in the upper left) that was not all that palatable to [Golan]. He used Processing and openFrameworks to create a program that lets him unwrap the donut into a flat image, or create a ring of video where the viewer is at the center and can scroll left or right to see the rest of the filmed environment. He released the source so you can adapt the program if you’re using
a different 360 video setup
.
[Thanks Kyle]

The project I present here (1) does this with video as well as stills; (2) can be trivially modified to work with *real-time* polar video fed from the Bloggie’s analog output, and (3) offer complete source code for popular open-source programming toolkits. Being able to unwarp real-time video means that it is then possible to create computer-vision based interactions that use panoramic video — for example, 360-degree movement detection or face recognition.CKnopp: Sony has released Bloggie unwarping software for Windows, but not Mac or Linux; that was part of my motivation in releasing code for the cross-platform Processing and OpenFrameworks environments, which can compile across all three operating systems. I also agree that Sony’s Windows software is not that great; for example, it assumes that the Bloggie lens is always perfectly centered, when in fact, it has quite a range of movement.Whatnot: I can’t explain why the Bloggie switches to a lower resolution for the panoramic video. It’s dumb! Interestingly, it’s only for the video; the Bloggie can take higher-resolution (5MP) panoramic stills.Golan",

iFixit traveled all the way to Japan to bring you this
iPhone 4 teardown
, only to be shipped the device unexpectedly
two days early
!
We were surprised that the A4 processor (its naked body
displayed for the world
this past April) contained within the iPhone 4 had 512MB of ram, compared to the 256MB of the iPad. Other features include the 1420mAh battery (201mAh more than the
3Gs
), 5MP rear camera and front VGA camera, and the use of
micro-sim
.
Frankly, we don’t see ourselves getting the device immediately, but how excited are you for the iPhone 4?

However, once it’s finished generating, it effectively goes on “standby” until input is detected (via a callbacks or “intents”, I think). To achieve an actual background application (like a media player), you have to write a service.The advantage of this method, imho?For (a stupid) example, say something is taking a while to download inside an app. You decide that it’d be a good idea to go run off and check mail.Fruit: You *SUSPEND* the app that’s downloading. You check your mail. You come back. Your download resumes (or is reset, since connection lost)Android: You switch out the download. You check your mail while the download is still running (lower priority, presumably). You come back. Your download is closer to completion / completed.As a developer, why would I write a background task for something that might come up only once in a while?However, as it was said before… It doesn’t matter. iPhone didn’t really need multitasking. I mean, look how popular they are anyway. They could sell a shiny iCrap and people would buy it. I don’t care. I don’t buy it. I did, however, hope that Palm would have sold better.

Another Take On A Bicycle Built For Two

We normally advocate wearing a helmet when biking in case you get hit by a car. In this case the guy on the bottom of
this double-decker bicycle
should wear a helmet to avoid a boot to the head. When we started watching the video after the break we thought that [James] had just built a really really
high bike
. Not the case, he built an over-under tandem bicycle. What’s more outrageous? Check out that killer kick-stand twenty seconds into the clip.

Next HOPE Badge Hacking Primer

"msp430",
"next hope",
"OpenAMD",
"pic"
] |
[Travis Goodspeed] is taking
a look at the attendee badges for this year’s Next HOPE
conference. He’s given us a pretty good look at what is on the board, what it means to you, and how you can get at it. Of course the final hardware specs are a secret until conference time, but this will help you get some ideas and ensure that you bring the right add-on hardware. We normally try not to do too much quoting, but one of [Travis’] statements literally makes us laugh out loud (as opposed to what most people describe as lol):
“These badges are active RFID tags which beacon the position of each attendee a few times a second, so that the god damned devil army of lies–by which I mean the Next HOPE badge committee–can track each attendee around the Hotel Pennsylvania.”
No matter how you feel about the badge committee, the tradition of hacking conference badges is a fun, rewarding, and often frustration past-time. The badges are actually using the concept of OpenAMD. The last three letters stand for Attendee Meta Data which is an evolving concept. How can meta data about attendees be useful to all involved in a non-invasive way? How about associating yourself with a concept, like microcontroller programming. What if you could search to find out where other people interested in that are right now? Could be great… could end up in an impromptu meeting around the restrooms for no good reason. Either way, take a look at the teaser video covering the topic after the break.
Oh, one more note about the hardware. This year they’re moving away from PIC based badges to the more energy-efficient MSP430 line. It’s not one of the value-line processors that
the Launchpad
is meant for, but this bigger-brother ‘F’ chip will be no problem to work with if you’ve already spent some time with the ‘G’ series.

The Atari 2600
pause circuit is now available in a kit
form. We saw this pause method
back in February
and the kit uses the same circuit. We don’t really need a kit for this, the board is very simple to throw together. But we do appreciate the
detailed installation instructions (PDF)
that accompany it. After all, you don’t want to kill you classic gaming rig with a botched install.

PlayStation 2 Portable

"portable",
"ps2"

[Raizer04] just completed his
PlayStation 2 portable build
. He feels that the PS2 hardware has much more to offer than the PSP and that’s why he chose to cram the PS2 slim hardware into a portable case. He started with an electronic toy to serve as a case donor and used bondo to form openings for the controller, speakers, lights, and screen. A beautiful paint job and some metal work resulted in the pleasant finish seen above. On the back you’ll find a lighted case fan, hard drive, and USB port. There’s no optical drive as games are loaded from a thumb drive. Take a look at the demo video after the break, but do yourself a favor and turn your sound all the way down first.
If this doesn’t quench your thirst for portable console projects you might also take a look at
this N64 build
.

[Johnny Carlo] put another spin on clock displays with his
Propeller-based Morse Code clock
. He repurposed a tap light, using the tap function as a switch input and actuating the bulb inside with the help of a transistor. If you want to know the time just give it a tap and the device will transmit back to you in a series of flashes. This is great if you’re contemplating a career as a Navy Signalman or just need
another way to practice Morse Code
.

TI Makes A Big Bid For The Hobby Market

"ti"
] |
This morning Texas Instruments unveiled Launchpad, a development platform for their low-cost MSP430 line of microcontrollers. We’ve seen these chips before, most notably in the
ez430 Chronos sports watch
. We see this as a bid for the hobby market currently enjoyed by Arduino, PIC, AVR, and others. TI’s biggest selling point is price, but we’re going to wait to share that with you. Join us after the break to see what the package offers, then decide if the price is right.
What is it?
We received a contact request on our tip line from a public relations firm on behalf of Texas Instruments. The video conference paired us with one of their engineers who took us through the details of the package, mentioning the low price tag every minute or so. Launchpad is a programming and development board for the
TI MSP430
. It has a machined DIP socket that can accept chips with up to 20 pins. All of these pins are broken out to the header ports on either side of the board, which resemble the Arduino layout to us. Good news, unlike the Arduino the header spacing falls into the 0.1″ divisions necessary to interface with common protoboard. TI is also looking for community involvement, pushing thier
Lunchapad Wiki
to help you get stated and asking that you add you knowledge as you find success with the 16-bit platform.
What’s inside?
Each Launchpad device comes with a whole lot of goodness. In addition to the board itself you get a 0.5 meter USB cable, two pin headers and two pin sockets for the pin breakout pads, two different MSP430 microprocessors (
MSP430G2211
and
MSP430G2231
), and two free IDEs;
Code Composer Studio 4
and
IAR Embedded Workbench Kickstart
(note that the latter has a 4K or 8K code limitation depending on the processor used).
Price
Hands down TI is trying to make price the biggest issue with this release. The presentation we were given included the price in large red numbers on seven of the thirteen slides. So here it is: Launchpad will set you back four dollars and thirty cents. And for now shipping is included.
Conclusion
It’s important to note that we haven’t had the board in hand yet. That being said, for $4.30 it’s worth the risk just to get the USB cable and a couple of processors. We’re amazed that they’ve beaten back the price to this point and delighted that you get the programmer and two microcontrollers, not to mention the other components. We like the fact that they didn’t develop an alternative language like Arduino did for the AVR controllers. This makes it easy to clear the hurdle of setting up a programmer, IDE and toolchain, and get right down to developing in C. After all, the chips are dirt cheap and quite powerful. You may remember 3000 of them from
a project we saw over the weekend
.
We’d imagine the initial demand will be quite high and hope they have the stock to keep up.

Granted it’s not 1:2 comparison to the 16bit MSP430, but I think the arduino can hold a lot more than 4 or 8K of code [citation needed].

PSP Homebrew Using The Half-Byte Loader

[Rich] tipped us off about
the Half-Byte Loader
which lets you run homebrew on late-model Sony PlayStation Portables. Above you can see a PSP Go running Doom (a screenshot from the video after the break), which is a prerequisite for any cracked device. HBL uses an exploit in the game demo of Patapon 2, which is free for download. A crafted game save loaded onto a Memory Stick gets you to the loader when selected from the continue menu of the game. Right now this method works on all know firmware version 5.0 and higher. Who knows when Sony will
take action to kill an exploit
like this one.

Audio Breakout Box For MacBook Pro

[Billy] wanted to use the audio connector on his MacBook Pro for input and output at the same time. He knew it could be done because Apple sells headphones with built-in microphones that work with the computer. He set out to
build a breakout box
so that he could connect the components of his choice to the single port. Using a scart-RCA adaptor box he scrapped the scart plug and wired the RCA jacks to the Apple headphone wires. He can now patch the pickup of his guitar to the mic connector, send it through the MacBook, and run the output back to his guitar amp.

There’s a lot of macs in the desktop publishing trade, and Apple has been throwing non standard 3.5 mm audio jacks (or no audio jacks, or an almost 3.5 mm jack for proprietary speakers that would fry anything else you plugged in) in to the mix semi-randomly since about 2002. A lot of people using those macs have started to use VoIP or recording tools for various reasons, and one by one they reach to the back of their machines only to find that a 30 year standard vanished when nobody was looking.Apple does the same thing with video, too. They swapped out the full size DVI port with a miniature proprietary one, and every year they swap a pin and move a plastic tab around so you need to buy a $30 dongle for your $1500 machine. Anyone remember the “there’s no step three!” advertising push that came with the G3 iMacs in the late 90’s? Having a half dozen dongles, adapters, and breakouts sticking out the sides of the box is one hell of a backslide.Being able to thumb your nose at even one of those iDapters is a good thing.",

[Danny] added
wireless charging to his HTC Evo
. The hard work was already done for him by Palm, it was just a matter of adding that hardware to his phone. A Touchstone induction charging kit for the Palm Pre will cost you just over $40 for the base station and a replacement back cover. [Danny’s] method removes the induction coil from that cover a relocates inside the case of the Evo. He routes two wires around the battery and solders them to positive and ground connections on the board. Once it’s back together the device
draws power without any wires
.

"content": "You know, for all the plugs that people plug in, and LEAVE plugged in, and all the manufacturing resources that go into making all of those plugs…What if your charging pad operated in a micro-power state when not in use. Only the tiniest of trickle, utilized for monitoring for the presence of devices. If a device is placed on the pad, a small magnet in the device could trigger the pad to power up and start an inductive coil in the area of the pad nearest the activated region. When the device is charged, the unit powers down, and occasionally comes back up to trickle charge the unit for a short burst every now and then. Using high efficiency monitoring circuitry, I think that whatever inefficiencies may exist in the inductive charging process, could easily be offset by power savings found when the pad is not in use and shuts down. There is also the savings of not needing half a dozen wall warts to be manufactured, and a new one with every new device.The inefficiency complaints really only can be counted against dumb devices. Smart devices are where it’s at. Power as required, when required, and never more than needed.The other argument is that one can’t ever forget to plug in their phone or iPod if they need only set it down each night. A busy office drone can set the phone down and pick it up and run without fumbling over which wires go where. There is of course, the aesthetic as well.I’ll bet that a well designed smart inductive charger can be made to waste less power with controlled inactivity, than wall warts left plugged in perpetually.Lastly, I’m amazed that some people here try to dismiss the durability issue, simply because they’ve never seen a broken connector. Just because you’ve never seen the problem doesn’t discredit the validity of the claims of the many who have seen it. A small connector, frequently used, WILL EVENTUALLY FAIL.Good engineering designs for all the possibilities that a wide variety of consumer can throw at the product. Poor engineering expects all users to adapt to it’s demands. Remember DOS. It was an amazingly efficient OS that took very little memory… but it was also quite limited, and required users to learn extensive lists of commands and modifiers. GUIs took it’s place and the world hasn’t looked back. GUIs are an example of engineering adapting to the user. Trying to get the whole world to “be careful” plugging and unplugging their phone cords, and asking them to unplug wall warts when not in use is simply not going to work. Some will get it, and do it. Some simply won’t care, and will just replace the cord when it goes bad. Others won’t even understand why it’s an issue… God, I’ve meet people like that. There is NO HOPE of changing those types. Rather than let them keep wasting resources with damaged product and a dozen wall warts persistently and constantly sucking juice, why not design the smart inductive pad that knows how to shut off, knows how to manage power draw, and eliminates a point of breakage, therefore reducing the amount of wasteful manufacturing of and endless stream of wall warts.Criticism of this technology does us no good. All our technologies had to take baby steps, and someday inductive charging will mature.Richfiles",

The principle is basically a simple coreless transformer they use it in electric tooth brushes.Ok the loops are tuned better and can be retuned on the fly but the base tech has never changed.Not to detract from its handyness ,it’s a nice feature just a bit greedy on energy because of its higher lossy nature.I have used it many times.When you need a fully watertight system for example inductive charging is ideal , as is indcutively coupled communications (just like RFID) you can literally pot your entire system in solid epoxy resin as long as you never need to get it back out :D",

Gaming’s Newest Accessory: Headbands

These aren’t terrorists, they’re electrical engineering students. For their final project they developed
a headband and rifle input system for the NES
. The controllers send data to a laptop which then maps out the inputs to NES controller commands and sends them to an original NES console, no emulation here.
The controllers in the headband and rifle are
Firefly sensor network nodes
. Originally, [Kevin] and [Evan] tried using accelerometers for motion information but found the data do be unreliable. After an upgrade to gyroscope modules the interface is much more responsive, as seen about 3:50 into the video after the break. We like seeing
motion controller hacks
and we appreciate the choice of a classic system (and lesser known game title). This really makes it a whole different game.

More checks than you can imagine :DSo Kevin, if you ever check out these comments, I loved working with you all semester. Taking ESE 350 was definitely the right decision :)Oh, and to all the hackaday people who see a typo and feel the need to comment on that, thereby missing the sheer awesomeness of this project?

For those who have asked why we didn’t use the Wiimote for this project, well that would involve hacking the actual game code of Cabal to support absolute positioning of the rifle’s crosshair. Otherwise, the best we would have been able to accomplish with the Wiimote is about what we ended up getting by creating our own controller system (moving Wiimote virtually “presses” corresponding direction on the dpad and stops when you stop moving the Wiimote). Plus, hacking Cabal’s game code wouldn’t let our system work with all games on the console.In response to bwmetz’s comment, unfortunately no, Cabal does not support the NES Zapper. That’s one of the reasons we pursued this project. It just seemed obvious to us that a great shooter game like Cabal should work with some sort of rifle controller.In response to Wouter Groenewold’s comment, at one point we actually talked about changing the project to finding a solution to getting the NES Zapper to work with newer televisions, but decided against it because of our time/resource constraints. :)And Evan, dude, thanks so much for taking ESE 350 with me.

This final project at MIT turned out quite nice. It is a
CNC mill that cost under $100 to make
. The tolerances are pretty tight as you can see in the pictures of the PCBs he has milled. He shows that he can even mill mild steel. It is a pretty brief writeup, but you can download build instructions and pcb files.

Swarm Light At Art Basel

What has 9000 LEDs, 3000 MSP430 processors, six XMOS XC-2 Ethernet modules, and goes blinkity-blink-blink? It’s
Swarm Light
, an art installation shown at this year’s
Art Basel exhibition
. [Fredrik Petrini] worked on the hardware that went into building the group of three 3D cubes of LED light modules. Unlike so many art pieces we see he shared the design details of the piece. In the image above you can tell that each cube encompasses several rods of LED modules. Each rod as three rails that provide power, ground, and serial data in addition to serving as the physical structure. Each module has three LEDs on it controlled by one MSP430 processor. The XMOS units each control half of the rods in a cube, getting their instructions over an Ethernet connection from a PC running a program on a .NET framework. It would be an understatement to say this is just a upscaled
LED cube
. Check out the exhibit in action after the break. It uses an algorithm to analyze the music, taking input from the ambient sound in the room, to control the light fluctuation.

Tetris Code Theory Explained

"tetris"
] |
[Graham] designed this
PIC based Tetris game on a single board
. The hardware is quite nice but we enjoyed his explanation of the graphics algorithm that he used. Having
coded Tetris from the ground up
ourselves we understand how difficult it is to explain how the program works. Tracking pieces already on the board as well as moving pieces, making sure that rotation won’t cause a collision with another piece or go out-of-bounds, and looking for completed lines all add up to one bid headache.
[Graham’s] method for handling rotation involves choosing a point around which to rotate, measuring how this affects each pixel in the piece, and then checking those pixels for overlaps. It may take a couple of readings, but he’s done a brilliant job of making it understandable. There’s a demo after the break and the link at the top takes you to his treatise on Tetris.

Read this line from the hack a day text;>>ourselves we understand how difficult>>it is to explain how the program works.No, it isn’t. If you’ve got more than a few bytes of memory to play with you don’t even need to do bit shifting… You can be very lazy and use your smallest native unit for each pixel! You have an 2 dimension array that has your game state and an array + x/y bounds descriptors for the pieces, the idea is to OR the pieces on to the game state array. You can do bounds checking by checking that the left edge of the piece isn’t out of the screen and left edge + piece width + current offset isn’t bigger than the screen when the user tries to move it left or right. Each time the piece moves down you compare the bottom of the piece array with what is “below” it in the state array, then you check the next line up,.. If there is a collision at any point the piece stops falling (I think the official rules include some grace time in which the player can adjust the piece). before the piece rotates you have to check the rotation will fit in the current state.. which is a just case of iterating over the state and piece arrays.When the piece has stopped falling you OR it into the state array. Then you check for complete lines.. which is (again!) just a case of iterating over the state array to find lines that are complete.There you go, I’ve just explained this terribly complex piece of computer science for you. Use it wisely.The data structures and logic are all very simple. Which is why there are lots and lots of tetris-like games out there on everything from desktop computers to hacked printer firmwares.",

I commend the guy for his efforts, but I have to be honest here – we’ve all done tetris!I think it was about a decade ago that I threw together Javascript Tetris. It took me close to 6 hours to create from scratch (much of that just learning the javascript) – this is with no former programming experience…Tetris isn’t that hard if you can think even slightly analytically…But then again, maybe my perspective is biased? Since then I’ve found everything including mario clones, 2D rendering engines, compiler frontends, and java servers to be challenging yet doable. I assumed HackaDay would be filled with more analytical engineer types than creative artists, but maybe I’m wrong? There are a lot of very creative hacks and gadgets posted to this site – many requiring extensive technical expertise – but that says nothing about the editors.So maybe his rotation algorithm really isn’t obvious to HaD’s editors? Maybe it is really impressive to them? :/",

If you can manage shifts etc you can use. bits for this *wowza!*, if you are using. tilemaps i.e have more than 1 bit graphics. you would have a tile number here and check. for anything that isn’t 0x00 in your. checking routines.0x08: pointer to next rotation (length depends on how big your pointers are) The last rotation points back to the original form.When the piece is rotated you don’t need to do any rotation in ram.. you can find what you need using the pointer and because the last piece loops back to first you don’t need any logic to wrap around.You can use a table of pointers to the pieces and use a “random” offset to piece the starting piece + rotation (I think the official rules state that all pieces start at the initial form though.. so you would only put those into your table). On a micro you are likely to have lots of flash rom and very little data memory so use static data over generating stuff in ram where ever you can.Please feel free to use this highly sensitive data under the terms of the GPL documentation license.",

Thanks too for the feedback guys.The intention of the project was to explore 2D graphic algorithms in aid for someone else (and for my own code tool-kit).For me, and plenty of other people out there – 2D graphics on a microcontroller is a pretty big leap forward.Understandably there are always going to be alternative approaches, some of which Cantido has politely suggested.@Cantido>I wonder why he’s bother to rotate (graphically) pieces in code when it would easier just to have the pieces rotated in the program data…At all stages of the project, an important feature for me was scalability. A number of different methods were trialled, and compared for performance. Rotating the objects with the 2D affine matrix method allows fast, scalable rotations (compared to many other techniques).The approach could easily be used in other retro games and much larger screens. There are a few ways to optimise the algorithm to suit larger screen areas (like GLCDs etc). More on that another time perhaps.You would be surprised as to how little information I could find online regarding PIC Microcontrollers and Tetris (let alone 2D graphics). Google appears to have taken my article straight to the top 3 for a few searches: “pic micro tetris”, “pic micro 2d graphics”.Perhaps the project is popular though usually finds itself the too ‘hard basket’ when working with the limitations of a microcontroller?In any case, I hope there are several handy code snippets and techniques that other readers can use.",

Velosynth Annoys Those Around You As You Ride

We’ve always put stock in ‘the quieter the better’ when it comes to road bikes. You’ll find this truth if you spend 100k on the back wheel of someone with a sqeaky rear derailleur. But apparently the folks at Effalo never learned this lesson as they’ve produced
a bike computer that generates noise as you ride
.
Perhaps it just takes some ingenuity to turn this into a beautiful music maker along the lines of the
Force Trainer hack
. No problem because the velosynth is a hackable design. The case was made with a vacuum form and inside you’ll find a bunch of small breadboards. The
JeeNode
, which is an Arduino/Xbee combination, serves as the heart of the device by taking speed and acceleration data from the bicycle wheel. From there it is passed on to various modules, Bob’s your uncle, and sound comes out. Check out their sales pitch after the break and if you’re starting to get some ideas about using this check out
the open source info
they’ve provided.

This interesting box of buttons is a
talking poker tournament timer
. Full of useful tools like a binary time display, words of wisdom, countdowns to the end of the game, and even good old “bicycle built for two” mode (around 1:20). While we find it fairly difficult to understand, we applaud the feature list, especially the song. He used an Arduino with a voice shield, so there’s not much to the electronics side, but you can download his source code from his site.

X-Band Linear Rail SAR Imaging

"linear rail imaging",

[Greg Charvat] really wanted high resolution X-Band linear rail SAR imaging system. He wanted it bad enough to scrounge through parts at HAM radio swap meets until he had the bits to
build one himself
. The unit is used to take high resolution radar imaging. For example, the image above is constructed of push pins behind a foam wall. The
synthetic aperture radar
system came in at roughly $250. Not bad at all. You may have to dig through the links a bit to find the build information. Be sure to check out the
hardware gallery
and the
schematics
(pdf).

As far as pranks go, [Austin Shaf’s] wireless hidden water gun is a real treat. The video above goes over a brief explanation and shows the setup in action. The prankster holds onto a wireless AVR remote, and when the unsuspecting victim walks by, he activates a second AVR controlling a pump; spraying water everywhere.
While most of us are out of school by now, the project would still be a fun office or perhaps street prank. If you’re one for registering, schematics and source code can be found at
AVRFreaks
. Alternatively, check after the jump for a copy of both.

Can you beat
this robot at pool
? This sparks something of a “let the wookie win” attitude for us, but we still love to watch the video. This is
the PR2
playing pool thanks to the folks over at the Willow Garage. It uses a laser sensor to detect the legs of the pool table, and cameras to find the diamonds and balls at the playing surface rather than
using an overhead camera
. They cut down on the coding work needed by using
FastFiz
, an open source Billiards physics library. The final step was building an interface so the robot could use a cue. Check it out after the break (no pun intended).

Replacement Speedometer
|
Mike Szczys
|
[
"Transportation Hacks"

[
"arduino",
"speedometer"
] |
[Howard]
built his own replacement speedometer
for his truck after the original speedometer cable broke. He’s using surface mount components and produced a two-board design that is quite nice. When he tipped us off he mentioned that this is Arduino powered and uses a hall effect sensor. There’s not talk of this in his writeup but we gather that he’s just using the bootloader on an AVR chip and that he hall effect sensor measures the rotation of one of the wheels. When the vehicle isn’t moving the board alternates between max speed and trip distance. Once he’s on the roll it shows current speed.

"content": "He should do this for the fuel gauge. Fuel gauges in the states are extremely nonlinear. For example, the gauge on the 2001 Ford stays stationary at Full until the fuel tank drops below 90%, then it stays still at half-full from 60-40%, and then gets stuck near empty for a while too. It’s completely irritating and I’ve seen it on every car I’ve driven. I heard an interview with an auto-exec justifying that practice because consumers will like the car better if the gauge stays at full for much longer after they fill up the tank.",

"content": ">I heard an interview with an auto-exec justifying that practice because consumers will like the car better if the gauge stays at full for much longer after they fill up the tank.I’m not sure how true this is. My understanding is that it’s because fuel tanks have unusual shapes and the fuel gauge works due to a float connected to a rod in the tank. This provides variable resistance. The actual amount of remaining gas is not consistent because of the tank’s shape. Also, the gas sloshes around as the vehicle moves and the float moves with it, so what you’re seeing on the fuel gauge is actually an average estimated amount of gasoline in the tank. Lots cars attempt to correct for this in the car’s computer nowadays and quite a few do a very good job of it.Here’s a page that describes how they work and talks about exactly those caveats.http://www.howstuffworks.com/fuel-gauge.htm",

Speedometers that are driven by a sensor instead of cable are incredibly accurate, and in my experience as a technician are generally within 1-2mph of actual speed, even at highway speeds. This error is introduced by slight variations in tire diameter, and by variations in the speed markings on the speedo face itself.Basically, if you don’t have a broke-ass 80’s car, and have not drastically changed the outer diameter of your tires, your speedometer is quite accurate.Also, DanS, there is no reason for your speedo cable to break every other year. A good cable will last the lifetime of the vehicle. Sounds like you are not properly lubing the replacement cables, or are going below the minimum bend radius that the cable is rated for.",

I can only add this…In the UK, the speedometer and odometer are not checked at the annual Ministry of Transport test (MOT).However, in an effort to reduce instances of ‘clocking’, vehicle odometers are checked periodically to ensure consistency and reduce fraud. Without a functioning odometer, this is impossible.Also, despite rigorous calibration, the speed recorded by a police radar will always win in court. Their argument being that a DIY replacement speedo cannot be accurate.The only place where this build could be considered legal would be on private land where the rules of the road do not apply.I don’t know where the HE sensor is placed, but if it came off and the speedo was unable to accurately report the car’s speed, it’s an offence.

Thanks for all the comments, guys :)In answer to a few questions/points:1) a new speedo cable would have been cheaper and simpler, but not accurate on this truck as the wheels are a different diameter from the originals, so the speed was always incorrect. Also, it’s difficult on this truck to thread the speedo cable through the various bulkhead holes without half diassembling the thing first.2) Was this just an excuse to fit an arduino? Damn right it was – I did it cos it was fun. Also, I like lights and displays and things even if they’re not completely necessary3) Not sure about the UK law regarding speedos, but since the existing one was inaccurate to the point of being useless I can’t see anyone penalising me for using a more accurate home-made one4) This has been incredibly reliable and consistent – the HE sensor is (as someone guessed) fixed near the driveshaft, and there’s a little neodymium magnet glued to the shaft itself. Haven’t had any problems yet.5) Odometer / clocking: doesn’t apply on this vehicle. Too damn old. (it’s a 1969 vehicle, exempt from tax, seatbelts etc)6) If I get stopped for speeding I’m certainly not gonna blame the speedo :)7) I call it a truck – you can call it a car if you likeThanks for the feedback, peeps, nice to know it was worth taking pics and doing the write-up. I’ve learnt such a lot from other projects on this site it’s nice to be able to return the favour :)h",

Building A Cluster Of IPaq PCs

[Steven Pigeon] got his hands on ten iPaq computers that a friend acquired through an eBay auction. The older machines were in good condition but the march of technology had left them behind as casualties. He’s given them
new life by assembling a cluster
. The first order of business was testing the hardware to make sure it’s working. [Steven] used memtest86+ that comes along with the Ubuntu distribution of Linux to find one bad memory chip in the bunch (a revelation that took 10 hours to discover on the slow hardware). He assembled the unit above with MDF as a support structure and threaded rod to hang the boards. He ended up with a beautiful module and his next step is to choose the operating system that will pull the whole thing together.
We find this build every bit as beautiful as the
file cabinet cluster
. It’ll be interesting to check back with him and see what kind of performance he can get out of it.

With a new active fsp supply you save up to 80% of the energy. This is why I throw out all my old machines.Also why would you have cluster at home when you can get access for more and more like Amazon E2C. In case you would use it for distributed password cracking those are also exist, see freerainbowtables, wpacracker, plaintext info etc.I built an 8 core server with 16gb ram for compiling my apps because it can do the job with multiple threads in seconds but the machine mostly idling. Running tools like setihome are kinda pointless…",

Reverse GeoCache Puzzle Gets Downsized

[Markus] built his own
reverse geocache puzzle box
but on a smaller scale than
the original
. His is based around a PIC 18F2520 and powered by two AAA batteries. The user interface includes one button, a 16×2 character LCD, and a piezo speaker. The box unlocks itself when the GPS module inside detects the proper location on the globe. There is also a secret code that can be tapped on the button to unlock the box prematurely, and another to show the locations in which the user attempted to open the box. This build doesn’t leave much room for a payload, but [Markus] did a great job designing the board and making the components fit as efficiently as possible.

Nixie Voltmeter Clock
[Gmglickman] built
a clock out of an old digital voltmeter
. The Fluke 8300A came out in 1969 and is featured in their
60 years of innovation slideshow
. What makes it a cool clock? The Voltmeter’s display is made up of Nixie tubes.
Easy optical encoder wheel generator
If you need to print out encoder wheels for your project there is
an online tool you can use
. It has almost any setting you would want to make a rotary encoder wheel.The black wheel can be used with
old mouse parts
and the checkered wheel with an optical sensor. [Thanks Bluewraith]
New CD without the CD
1-bit Symphony is a newly released album. It come in a CD jewel case but there’s no CD included. That’s because they’ve built
a circuit to playback their music
via a headphone jack. We didn’t see any info on what microcontroller was used, but we love the cleanliness of the design. This apparently
isn’t the first time
the artist has released an album like this either.[Thanks Juan]
Making a standard SIM work with the iPad
[Tony Million]
used a standard SIM
to reduce the monthly cost of using broadband on the iPad. This is the exact opposite of
using the iPad SIM in an iPhone
and requires that you cut down your standard SIM quite a lot. [Tony] did this because he imported his iPad to the UK from the United States and using AT&T wasn’t an option for him. [Thanks David]
16TB NAS is a thing of beauty
The Black Dwarf
is a sixteen terabyte network attached storage device that looks more like a display counter for high-end hard drives. We’d usually think of this as a closet or basement dweller, but an item this gorgeously crafted deserves a place of honor in your home or office. Documenting the entire process was as complex as the build itself. We like seeing the
time-lapse version
. [Thanks Howard via
Engadget

I get 100kb/s downloading over http or ftp, whereas I get upwards of 2mb/s from a torrent.I recently downloaded some free high resolution satelite images of the earth (truemarble), and the only option was torrents.There are hundreds, if not thousands of legitimate uses for the protocol… Throttling or blocking it is like closing off an alley in a city because of junkies. Sure, you look at it and say it’s full of nothing but criminals, but if you look closely you’ll see that legitimate businesses use it to recieve packages. Don’t blame the alley, don’t blame the protocol, it’s merely a conduit.PS: No, bittorrent is NOT the *only* method to get pirated stuff, you can get it through usenet, ftp, irc dcc, gnutella/morpheus/limewire, kazaa/fasttrack, directconnect, imesh, ares, emule, etc, etc, etc, etc… There are *countless* protocols you can use for piracy.",

[Lozzless] has a steady hand and plenty of confidence in his hacking skills. The video above is worth watching for the full eight minutes. In it you’ll see him convert a lens into what he calls a SuperMacro lens with a working aperture. The process involves fashioning a connector ring from a lens cap, modifying an
Electro-focus lens mount
, and assembling the parts to do his bidding. We don’t have the photography background to fully understand what he’s doing here, but we can appreciate the process, and the results are shown at the end of the clip.
[Thanks TommyC]

I doubt that the autofocus would work with this mod – although it’s connected electrically, the camera will get confused as the focusing now has to be done in a completely different way.I’ve used this lens before (the cheapy Canon 18-55 kit lens) in reverse for ultra-macro. You can simply hold it against the camera, but it’s quite difficult to get a sharp picture and you have to do the metering manually. A sort of half-way house between that and this lovely mod are the reversing mounts you can buy on eBay for a few pounds. They’re basically a filter thread glued to a bayonet mount…but of course you’ll have to set the aperture manually before reversing the lens.",

The most important thing is that you lose infinity-focus and that if focuses only on a spot, not a plane like a macro.Buy a second-hand one if you can’t afford new and you’ll see the difference.",

Get yourself a macro extension tube which has the EF electrical contacts passed through (this is the most expensive piece), solder on some wires, get a EF to 58mm adapter and, hack up a back lens cap in order pass through the contacts from the extension tube up to the back the lens. Now… mount as so: Camera -> hacked extension tube -> EF to 58mm adapter -> lens mounted backward -> hacked back cover with contacts. Yes.. its more complicated, but it also means you can disassemble it and still use the lens in its stock form, and you can use different length lenses as well (though you might need a different adapter ring than 58mm).",

Coachella Lamp

"Misc Hacks"

"decatron",
"nixie",
"ultraviolet",
"uv"
] |
This little art piece might be just the thing to add that mad scientist look to your room. It’s called
the Coachella lamp
and it makes use of several throwback display devices. At the top an Argon discharge lamp puts out ultraviolet light. Protruding from each of the four sides you can see a set of decatrons. There’s also four Nixie tube bar graphs standing tall from each corner of the base. The final touch is the colored glow in the center which is provided by LEDs. We’ve embedded some video of the device after the break.
The lamp is powered by a wall outlet and controlled with an Arduino. We’ve seen
deactrons used as timing devices
and would love to see some clock functionality added to the lamp. Trying to decipher the time from the different Nixie displays would put this up there with some of those other
hard to read timepieces

Arc Reactor Replica

Mike Szczys

[
"LED Hacks"
] |
[
"arc reactor",
"iron man"
] |
This Arc Reactor
is a great re-creation of the fictional source of Iron Man’s power. It’s really just a holder for a bunch of LED’s, but it exhibits some fine craftsmanship which we enjoy in any project. This rendition is much more true to the movie than
the last look-a-like we saw
. These might end up being for sale (the webpage narrative is kind of weird) but you really shouldn’t be wearing this kind of thing around unless you made it yourself, or if you can add it to some kind of
Iron Man simulator
.

Nerf Sentry Turret

"Toy Hacks"

"motion",
"nerf",
"netbook",
"sentry",
"webcam"
] |
With exams behind him [Adam Greig] had time to make
a Nerf sentry gun
. It’s actually quite easy to pull everything together. He’s got a netbook running
Motion
, an open source motion sensing program for use with a webcam. When movement is detected an Arduino, connected via a USB cable, actuates a servo to pull the trigger of the gun. The turret itself has seen a battery upgrade that increases the firing speed. It’s fun to see hardware prototyping done with a few pencils and a fist full of cable ties. Check it out after the break.
This particular toy, the Nerf N-Strike Vulcan, has become quite a popular starting point for turrent projects. We’ve seen
one that uses a motorized base
, and another that was part of
a final project at Cornell
.

Candle Stop Motion: How’s It Done?

[Ollie] tipped us off about a stop motion video that uses a grid of tea candles to animate some classically pixellated game graphics. The image above is obviously a game of pong in progress. It’s interesting to watch but for us the fun is trying to decide how it’s done. Click through the break to see the video and discuss the methodology.
[youtube=http://www.youtube.com/watch?v=EG127HdhWZQ]
Perhaps the most obvious method used here is plain old stop motion animation. You light the candles, take a picture, snuff the ones you don’t need and light new ones, and repeat. There’s also the thought that the creator let the video roll, walked through his planned frames, then edited out the filler video after the fact.
To us, one thing is missing. Whenever we put out a tea candle that’s been burning for some time it tends to let off a rather vigorous column of smoke. We don’t see that in the video. Our thought is that you take a picture of all the candles before they’re lit. You then take several shots of all the candles lit. The multiple shots are so that the video shows flickering flames. From there an image processing program can be used along with a layer mask to digitally stuff the candles that you don’t need for each frame. Below is our attempt at this using
The Gimp
. But we want to know how you would have done it so leave us a comment.

No Nonsense Mbed Development Demo

This
tweeting RFID reader
is a great working example for the mbed. When an RFID tag is read it is matched with the name of the owner and a Twitter message is sent out. This is very similar to the
RFID cat tracker
that used an Arduino.
The code is short and simple due to the use of available mbed libraries. The hardware needs just two extra modules, an RFID reader and an Ethernet socket. If you’re trying to decide if you can make the jump over to ARM development this certainly presents an easy learning curve and an opportunity to get comfortable with the code and the libraries before you make a purchase. It’s also a great set of test code to start with if you have an mbed and the two supplementary modules on hand. The quick video clip after the break will walk you through the components and the code.

This coil has no trouble shooting sparks across four meters of empty air. [Finn Hammer] has been putting in some long hours on this labor of love, and we put in some time reading through
his progress thread
. He started down this path about a year ago and every step of the way he produces beautiful work. We enjoy seeing his prototyping techniques, moving from concept to hand drawing to CAD diagram before starting the physical build. Check out the demo video after the break and as you read through his thread look for the green arrows that lead to other videos and resources.

[Clayton Boyer] took the electricity out of the useless machine,
making one that runs like a clock
. To this point, we’ve always seen these
useless machine use electric motors
. [Clayton’s] clever design uses a wind-up spring and a series of wooden gears to bring the fun, making it a great companion for the
binary adder
you built. The video above shows the inner workings and the design plans are for sale. We’d love to
print out the parts
or perhaps just laser-cut them from wood
like the legs of this spider bot
.

Joojoo Alternative OS Installations

Joojoo hacks are starting to trickle in as non-fanboys get their hands on the iPad alternative. The
custom OS forum
for the device tells the tale of successful installs of
Windows 7
,
OSX
,
Android
, and
Jolicloud
.
So far the only one to have
a how-to
is Windows 7, but we’re sure that will change quickly. When Microsoft’s offering is installed on the device it get about four hours of use per charge which is fairly decent. We’d love to get our hands on one and try it out with Android but the $499 price tag is still a hurdle for us. We’re not saying it’s over priced, as
it comes with a lot under the hood
. Even at that price we think it blows the
aPad
out of the water.
[Thanks Andy]

Careful! That Gas Pedal Is A Nexus One

Indeed, the gizmo above is meant to be used as a gas pedal. [Grant Skinner] came up with the idea to
control slot cars using an Android phone
as a gas pedal. He coded the software for the handset and a computer using Adobe AIR. Once connected, the computer is sent the accelerometer data from the phone, relaying the speed control to the slot car track with the aid of a Phidgets motor controller. See it ‘go’ after the break.
We’ve seen the Phidgets board used in several projects like the
augmented vending machine
and the
plotter white board
. What we haven’t seen is hacks that make use of AIR,
a framework we looked
at two years ago. If you’ve got hacks that make use of AIR
we want to hear about them
.

Win At Hangman, Gain Entry

Do not put anything in this box that you will need in a rush. You’ll have to
successfully guess the word in a game of hangman to gain entry
. He’s using an Atmega328 as the brains of this project with a rotary dial and an LCD for input and display. If you win, the box is unlocked and you can open it up to get whatever is inside. There are links to various tutorials along the way to help with each step, including the Arduino source code he used to build it. We think he should bump it up a notch and have the box destroy the contents if you fail. Sounds like fun, right?

[Pablo] likes to buy and repair broken cameras. When he was in need of a way to test the shutter speed,
his brother came up with a great idea
. Harvest the photo transistor from an old ball mouse. It turned out to be just as easy as it sounds. He plugs the circuit into some sound editing software to get the signal. We think this is pretty slick.

Because there are two different shutters in your average SLR (front and rear curtains released at different times) you need to ensure that they are moving at the same speed. Otherwise the image will get progressively more or less exposed as the two shutters move across the film plane. Two diodes placed at opposite sides of the film plane work very well. You can also measure the shutters’ total velocity which is important for a manual camera because the springs may become tired after many years, especially if you foolishly charged the shutter before putting the camera away in the cupboard for years ;-)@andrew: it really is that simple – for my soundcard anyway.",

This new toolkit, called
“Android” meets Arduino
, allows you to connect an Arduino to your device and communicate back and forth. You could trigger external events at the Arduino end when an event happens on your phone, or even trigger things on your phone side when something happens at the Arduino. We can’t wait to see the stuff people come up with beyond simple notifiers.

Unbricking With The Help Of Arduino

A
This bricked Eee PC came to [Janzo] for about $50. Everything was fine with it, except for the failed bios update that rendered it useless to the last owner. [Janzo] set to work with an Arduino on
a quest to repair the bios
. He looked up the datasheet for the EEPROM that stores the bios and did some delicate soldering to gain access to the power and data pins on the device. A bit of trial and error and he was able to read the registers. Some comparisons between the output file and the official Eee PC bios file in a HEX editor confirmed that the first 80 bytes were fine but after that something went wrong. After coding a quick Python script [Janzo] reflashed the chip and had the computer up and running again.
We’ve seen
Eee PC bios recovery
before. This is a very simple method because it makes use of the simplicity we find in the Arduino. Nice job.

Update: Flash_Destroyer Final Destroys EEPROM
|
Mike Szczys
|
[
"HackIt"
] |
[
"corrupt",
"destroyer",
"eeprom",
"flash"
] |
The
Flash_Destroyer finally succeeded
in rewriting that EEPROM until its demise. When we
originally looked at the device
it had already recorded 2.5 million successful rewrites. The first appearance of corrupt data occurred at 11,494,069 but that doesn’t tell the whole story. The chip kept working for another 200,000 rewrites before finally showing repeated data corruption.
We do find the writeup pretty interesting. There’s one thing that we can’t stop coming back to though. In the discussion of our original article [Tiago]
pointed out
that long-term data retention isn’t being tested here. If the abuse of that EEPROM had ended after say five million rewrites, would it have been able to hold the data long-term without corruption? Let us know what you think in the comments.
[Thanks Drone377]

To test the former, take 10 or so new EEPROM chips, choose a different number of writes to each chip, make the writes, wait a month, then measure the % of bits from each chip that differ from what was written. It might make a cool graph and might differ from vendor to vendor. I bet it’s a decreasing, negatively-accelerated hyperbolic or exponential function.",

Over 100,000 Lego pieces, 4 people a year to create, and a 12 foot by 12 foot chess board make this the
largest most awesome Lego hack
we’ve ever seen. Take that
Lego Printer
.
For a mere $30,000 you too can have such a setup.
Not a lot of information
is out yet, but we do know all the pieces are remote controlled via a PC with LabVIEW and a total of 38 NXT controllers are used. Oh, and of course you can see it live at the
2010 Brickworld
. Check out a video of a replayed game after the jump.

Distance Measurement Input Device

[Larry] put a different spin on
a television remote control
. He used an Arduino and an IR receiver to learn the codes from the factory remote. Now that he can use an IR LED to playback these signals he worked on an alternative to pressing buttons as the input. The ultrasonic range finder seen above allows him to wave his hand in front of the device to change channels and alter the volume levels. Check it out after the break.
There are many other ways that gestures could be used with this system, including
a laser based input
method. We’d like to see [Larry’s] system incorporated into
a coffee table of some kind
, as long as there was an opening for the range finder to work.

[Erich] rethought the use of a megaphone and ended up with this
Mega-Tape-O-Phone
. His first move was to ditch the megaphone’s amplifying circuitry in order to add his own based on an LM386 chip. From there a radio receiver joined the party followed by the guts of a tape player. He relocated the head of the tape deck to the end of a flexible cable and coated the outside of the megaphone bell with magnetic tape. Now he’s surfing the airwaves and scratching away happily.
The
use of the tape head has been seen here
before, but it was never in a mobile package like this is. Join us after the break for some video of this in action.

This security system called
G-spot
requires that you touch a special place on the car prior to attempting to start it. This is pretty slick as it could be completely un-obvious and doesn’t require any
special fobs
or
minor surgery
. With the right placement, no one would ever notice that you had touched it.

Standard connectors in portable devices would be great for the consumer, but then you wouldn’t purchase separate peripherals for ever portable you buy (lining the pockets of the companies licensing said peripherals). [Thijs] isn’t taking it lying down any longer. Realizing that the shape of the connector is one of the only things standing in the way, he built
an adapter to use iPod docks with Droid
. The hardware consists of a USB connector, audio jack, iPod connector, and a magnet. After working out the wiring it was just a matter of building a chassis
using polymorph
material. As you can see above, his expensive dock has no problem playing nicely with Droid because of his handy work.

PVC, wood, and some creativity bring
this Stargate duplicate
to life. [Mango] and his father started with AutoCad drawings taped together, and ended with the Stargate you see before you. Sure it’s not 22 foot in diameter and not made of
Naquadah
, but its inner ring rotates and dials like the real thing and it has all 39 symbols – hand carved. Catch a fun and entertaining video with the Stargate after the break.

The idea of
the Great Ball Contraption
is to take modules from many builders and combine them into one large machine. The modules need to find some way of moving LEGO soccer balls and basketballs from an input point to an exit are that passes them onto the next module. Some of them sort the balls, but in the end the eight-and-a-half-minute video above shows the orbs going around and around. That’s just fine with us, it’s no secret that we love
machines that are overly complicated
and may be
completely useless

They tell you where to expect to recieve the balls, and where to drop the balls, as well as how many balls per minute the average flow rate should be. Then, people fly from all over the world to meet up and hook their modules together to create an enormous collaborative contraption.See here for more info:http://www.teamhassenplug.org/GBC/",

[Colin] has cut his teeth with about fifteen PCB orders. He wrote
a tutorial describing the process
and sharing his tips on avoiding common problems. You may remember
our own How-To prepare designs for manufacture
early last year. In that post, [Ian] shared his veteran knowledge by outlining
BatchPCB’s
board design process. This time, [Colin] is using
Advanced Circuits
in Colorado as a board house, giving us more insight on how the different companies work. No matter who you choose for manufacturing, make sure you really understand how to properly format and troubleshoot your designs. It’ll end up saving you a lot of time and money.

That’s the number of PCBs I’ve ordered over the course of the past year, but good stuff anyway.The only thing I wish you could do from Eagle for Advanced Circuits was specify how to scale the drill file. Maybe 3 times out of every 4 they misscale the drill file and I get a million “missing soldermask” violations about 12 inches away from the edge of my board.One more thing you should always do for Adv. Circuits: if it’s a multi-layer board, GIVE THEM A LAYER STACKUP! They want to have a file which confirms which layers go where, what they mean (especially if you included a lot of “Drawing/Other” files).",

This way I can see if I can really mount that heatsink, if I can put a ribbon cable in the connector, etc.I do my own boards on my CNC, but I still do a lot of checks before, because paper is cheaper than PCB+mills+4 hours wait time :)",

The order is open to anybody (in the US, I assume).Boards are $5 per square inch for 3 copies, any shape within reason. Art deadline is 8am every other Monday (yesterday was the most recent), and boards arrive by the next Wednesday (used to be Monday, but new board house is slower).http://www.dorkbotpdx.org/wiki/pcb_orderWorking on a commercial prototype I have to say this order has saved me countless hours and probably over $1000 just in the last month or so. The 2-week cycle of order, populate, redo, order, rinse repeat is ideal. If there’s enough interest outside of Portland I’d love to see it become a weekly order ;-)Also, he’s looking at doing a 4-layer order as well, but it depends on both the current 2-layer boards being a little more popular, and there being enough interest in 4-layer ($10/sqin for the same 3 boards).",

As the summer heats up an air conditioning system is a necessity in many climates. [Grayson’s] system suffered some damage over the winter that caused it to vent its refrigerant, avoiding an explosive situation. Before he can chill out inside he’ll need to recharge it and he’s chosen to
use propane in his cooling system
. According to our friend Google this is not his original idea, but has been done many times before. [Grayson] makes the point that although propane is flammable it’s not necessarily any more dangerous in a fire than Chlorodiflouromethane, or R22, which is the nasty little gas that fled his system for its new home in the upper atmosphere.
The video above includes a brief explanation of recharging the system and the tools needed. We’d need to mill this over for quite a while before working up the gumption to give it a try. For now we’ll stick to [Grayson’s] more pedestrian hacks like
making some servo motors sing
or
easing our yard work woes
.

While on the other hand, if ANY Chlorinated fluorocarbon leaks in the presence of a flame it will produce phosgene gas which is about as lethal as it gets (LDL50 of 350 ppm) so no, the propane fill isn’t much different of a danger than the r22 is. Or the 20 gallons of unleaded in your gas tank etc. etc. But most HVAC people raise hell if anyone suggests using it because they would rather you pay them to come out and charge you anywhere from 300 to 1000% markup on everything they sell you + labor rates of 100 or more per hour. Take a look at how the HVAC lobby got congress to make it illegal to purchase a condenser with R410a even though it is supposed to be environmentally friendly. They want to buy a 4ton condenser for 1200 bucks and the charge their customer around 3 grand to install it in about 2-3 hours tops.",

I think the problem people are having with it is the thought of using something that is so highly explosive, it generates a visceral response, “Oh No! Propane in my house!” but this is understandable. alcohol, medicinal or drinking, is in small bottles, lighters carry a very small amount of butane, and camping bottles of propane and grill tanks rarely make it past the garage to the insides of the home. would you ever store paint thinner by your gas water heater? of course not, this mind set is pounded into us at a very early age and that programing kicks in when someone thinks of putting propane in an a/c unit.on the topic of salvaging R22, why not? if you are reasonably sure of its purity and contains no acids. When I replace a system, i’m required to reclaim the refrigerant anyway, I test it, if it passes, it goes into my personal collection. most of the time, I’m the one who has maintained it so I know it’s condition. no problem.The problem I have with someone doing something like this is simple, it’s hacking vs being a hack. I have no problem with hacking, I do it myself whenever I repair a piece of equipment, and I have the knowledge base to do it right, this insures that it will last a long time and be useful.Being a hack though has a definite negative connotation to it, and rightfully so. hacks don’t have the knowledge and can’t be bothered to do the necessary research to do the job right. and in a situation where propane is part of the equation, well, it’s more of a “is he/she dangerous,” question to me.",

If it’s a question of impurity, propane is a greater risk than used r22 that you can test.",

This is going to endanger someone who is unaware of the change. This is what I really have a problem with.

The gasoline vapors above the liquid gasoline would burn if there was sufficient oxygen, but it would quickly suffocate itself. Even if there were enough energy released to sustain a flow of gasoline vapors out the filling portal, it would be anything but an explosion, just a slow burn. In a system containing propane in thin metal pipes, a rupture would quickly lead to a drop in pressure and the boiling of any liquid propane in the system. This also wouldn’t explode, but the sudden release of all of the propane in gas form would create an immediately dangerous situation that could cause a large fireball if there was an ignition source nearby.",

This has happened because someone used propane to charge an ac system and didn’t label the system as such. There-in lies the rub.Note to self: Don’t smoke a cigarette in an enclosed space after venting an unknown refrigerant into the aforementioned enclosed space.Another note to self: If I ever use propane as a refrigerant, maybe make a note of it somewhere, just in case someone other than myself works on it. I’m pretty sure that propane is the future of refrigeration, so probably more and more technicians will be aware of the potentiality of propane in any system and take additional precautions, like ventilating the space, which seems like a precaution that anyone would take. Like I said, someone exploded themselves by smoking a cigarette without ventilating (Australians) after discharging an AC system that contained propane.",

I’m not ready to go do this to my system just yet, but I do recognize that propane is not explosive until it’s mixed with the right amount of oxygen. Even with a bad leak, the worst that’s likely to happen is that the leak point turns into a pilot light or small torch. Yeah, it might start a fire… burn his house down, even. But that’s a far cry from a freaking explosion. Far more likely is that the propane slowly leaks out until the system stops cooling efficiently, just like the original R22. No drama.",

Personally I won’t heat with NG or Propane because I think propane stoves and hot water tanks are too much of a bother and too dangerous with many cases of them exploding being documented over the years. Yet I would have no problem with an heat pump system that used propane because I know the chances of that system malfunctioning and causing health problems would be nil.",

"content": "My apologies to the grammar/spelling police. However it still addressed the concepts that many are mistaken about.Personally I think you should stick to regular refrigerants because apparently your fear of change is hyper-elevated. As is your exaggerated idea that the average homeowner works on his AC system.My point was that it would be extremely rare that those “right” conditions would ever occur. If you consider that many new refrigerators already come with propane in them and the other household appliances that are already run on massive amounts of propane or natural gas. Suddenly you are concerned about a relatively miniscule amount of propane in a sealed system. Now if you expressed concern about an r-12 system leaking next to a gas hot water heater I’d be impressed. But all you do is freak out about a system hissing?Assuming I lived in a housing development I wouldn’t want my neighbor working on his gas hot water heater without knowing what he is doing. I’d be 100 times more concerned about a hiss coming from a regular propane water heater than i’d ever worry about from an AC system. One reason is that a loud hiss from an AC system is going to last a pretty short time. Remember it takes only roughly half as much propane to do the same job in refrigeration. His hissing hot water heater can level the whole block. Propane has to be the right perfect mixture before it will burn and then it needs an ignition source. If a water heater is hissing it could hiss for days because it has a huge tank hooked to it. If my neighbors system was hissing I’d have to call him and tell him about it. After I called him it would be done leaking out.Your priorities of what to fear are totally messed up. You don’t need propane to have dangerous screwups causing explosions. R-22 systems have exploded before due to tech error. In one case the tech barely escaped with his life. Look it up. After analysing all the physics involved I don’t find propane significantly dangerous at all. Mostly for two reasons. 1. the amount used is very small. 2. mixtures have to be just right for propane to actually burn. Getting those conditions just right on accident would be extremely rare.Besides it is job security for all techs. Your industry can no lobby for a law to prevent unqualified people from working on their AC systems. I would probably worry more about stupid techs not following procedure. I have spent enough time with various techs to know that many of them barely know anything about the physics behind their own field of work.Definitely less dangerous than other stuff being used in cars and homes. Suggest you relax about it.",

I was upset with the fact that I had just wasted my time with the class.hypothetical: do you want the owner of the house that is less than 50 feet away from you, soldering his air conditioner lines, not knowing if he has r22 or propane in his system? not evacuating the system before he charges it up from a propane fuel tank? and then running it? what would you do if you heard a loud hiss from it?It’s not the smart ones i have a problems with, its with the ones under the dunning-kruger effect.",

This tech does NOT make it easier to blow yourself up. For one there is nothing really new here. This would actually make it harder. If you really want to blow yourself up you will fill balloons with oxygen and acetylene with a fuse attached. I have never done it but I hear it makes a big bang. Or you could make your own gas from water and fill balloons and put a fuse on it. I have the machines to make hydrogen and oxygen, and I have tanks of acetylene. See? tons easier ways to blow stuff up then messing with propane.Finally a real question! A departure from blowhard trolling. But it’s an obvious and stupid question. Grill propane is not clean enough. Nor does it have the right mix of gases. Refrigerant hydrocarbons really should be a 3 gas mix and have to be very pure and clean, totally devoid of any moisture. Well at least if you want your system to last very long. And quite frankly I wouldn’t put it in the evaporative unit either, running or not. Condensing unit? really? I sure hope you aren’t running the system while you pull that little trick.You got any more duh style questions?

You probably only caught the last page of comments in your search.My stance has ALWAYS been that fuel grade propane is not nearly pure enough to be used in refrigeration, but it has been overshadowed by the “OMG explosive gas” viewpoint. And my issue with the yahoos that do this sort of thing comes from the experience of seeing a system that was not labeled properly if the refrigerant was changed. Documentation is CRUCIAL in this field, I hope you would agree with that.Thankfully the only calls I have been on where someone didn’t document necessary information were electrical in nature. I got shocked as a result and pitched a screaming fit at the person who took short cuts, but this just goes to show how some people JUST DON’T KNOW BETTER.

IPad Hacked To Include A Verizon MiFi

Finally, some hardware hacking on an iPad. Finding the 3G connection that came with the iPad lacking, this industrious hacker
yanked it out and replaced it with the guts from a MiFi
. At the cost of his GPS, he’s gained a better connection and is now a wifi hotspot. It wasn’t horribly complex, but he did have to do a tiny bit more than just plug and play.

We’re hearing complaints everywhere about the noisemakers called Vuvuzelas during the world cup. Whether you are a fan of the sport or not, you can appreciate when a fellow hacker gets annoyed and start hacking. [Tube] has created a
software filter that manages to remove the sound of the Vuvuzela from the videos
. He shares the process of how it was all created, using Logic Express and a Mac mini (
Google translation
). Maybe this will also provide some relief from the constant stream of Vuvuzela whining as well.

[Jeri]
got her hands on some of the DuPont Luxprint EL ink
and had some fun conducting experiments. She tried different materials for the base and the display itself. Not only does she just play with materials, she also tears apart a VFD and an LCD to see if she could use them for parts. The LCD turned out to be the most successful. We saw this stuff show up at the
Bay Area Maker Faire
and we’re excited to see it become more accessible.

One of the side affects of the experiments I did with homebrew tubes can be seen on the tenth image down the page at:http://www.hpfriedrichs.com/bks-ioa-gallery1.htmThis was simply a glow tube– air at reduced pressure with two electrodes and a discharge between them. Over time, the impact of electrons eroded the copper tube and the freed material plated itself on the interior of the glass.This coating, while dark brown in the photo, was actually quite transparent, yet, if you touched the probes of a DMM to the glass, it readily conducted electricity. Cool stuff.If you were to fashion a mask with a desired pattern on it, place it in contact with your glass substrate, and then place it in an evacuated chamber with a glow discharge and suitable sacrificial electrodes (i’d start with copper), you might be able to make a “contact print” of your desired electrode pattern. Follow up with the EL paint, and make custom displays.Personally, I have considered revisiting the sputtering idea for the purpose of laying patterns of lead on to glass. The idea is to then react the metal layer with sulfur fumes to create a lead-sulfide semiconductor. A primitive FET or a thermistor would be possible end-products.Speaking of copper films, if you thumb through the photo set on my site, you can see examples of some cuprous oxide transistors I tinkered with. A sputtered layer of copper, properly oxidized, might also form the basis for a primitive FET.I can be reached through my website if you need details of my equipment.PeteAC7ZL",

It seems silicon had some competition back then.-JerI’ll check out your website.",

World’s Slowest Porsche, Still Faster Than My Car

Well, maybe the title is not so true.
This “Porsche” GT3
‘s construction is a bit
unorthodox
, the chassis looks to be aluminum tubing, with bicycle tires and other man-powered parts for propulsion. The body is entirely plastic and tape, yeah…gold…foil…tape. Hey, when you really really want to
turn someones head
.
Regardless, the car even comes complete with working lights, horn, doors, trunk, and lexan windows. Sure it will never go 0 to 60 (
yet
), but the mileage is amazing! Follow an amusing video of it after the rift.

We came across
a couple of videos of this toddler android
. It sits up, rolls over, and responds to humans around it using visual, audio, and sensor inputs. After the break you will see that the movements are quite like that of a young child. The giveaway is the weight of the robot which is evident when its handlers trying to help it get untangled from that blanket. It seems to respond to individuals around with a smile and a twinkle of its… errr… camera eye. We wonder if it would find delight in
knocking down some
dominoes
.

[Rossum’s] latest project just hit and as usual, he doesn’t disappoint. Using an ARM cortex M0
he built a gaming system for less than $3
in parts. The M0 is a bit underpowered for this but at $1 it can’t be beat in price. He worked some video generation voodoo to get the signal he wanted but also mentions that upgrading to a bit more expensive chip like the
Cortex M3
would solve this problem. The other part of the gaming system is an analog stick (again for about $1) that is the only input for the system.
Can’t say that you remember hearing about [Rossum] before? Go back and check out his

Painting with light
[Jo0ngle] wanted a fun toy and an easy conversation piece. He painted a square on the back of his door with some glow-in-the-dark paint. Now he can draw on it using a blu-ray laser or a UV flashlight. Either way,
the effect
is quite pleasing. [Thanks Justin]
Resistor decoder rings
This
resistor reference card
allows you to spin a wheel and dial in the resistor color code for easy reading. We know, you have the simple act of reading resistor code down cold by now. This is still a fun idea that you might use if you’re ever helping someone get into electronics. [Thanks Osgeld]
Resistor bending template
Speaking of resistors, [Jerome] helped us out by designing
a resistor bending template
. He’s actually marketing himself at the same time. His bending template is folded from one of his business cards, which he came up with after being inspired by some of the
unique business cards
we’ve covered in the past.
Fake stained glass using old PCBs
[Agg] floated some old PCBs to his friend [Dan] the mason. [Dan] proceeded to turn out an amazing looking stained glass window unit using the colorful leftovers. The picture above doesn’t do it justice, you have to
click through to see the real art
.
Monovelo monowheel
[Ernst] asked if we’d heard of the Monovelo monowheel. Well we hadn’t. It’s a human-powered vehicle where you sit inside of one large wheel. We don’t see ourselves building one or riding one, but we enjoyed
watching someone
else do so. We’d like to catch somebody commuting to work with one of these. Seeing this in the bike lane will brighten up anyone’s day.

[Jerome Demers] sent us his
extremely detailed
semester project. The two part system consists of PICs connected to XBee modules and accelerometers. By using the device a coach can monitor an athlete and correct their minute mistakes.
Did we mention [Jerome] was very detailed? He also goes into the particulars of designing the circuit, using
solder paste
and baking, designing and
laser cutting a case
, and even some
fun stories
. Well worth the read if you have the time.

He then remove the board and goes into a bath to get the holes electrolysis (or something), they et plated. He rince the board,(I am probably missing some steps) put it back in the CNC and get the rest of the job done. The technician (Serge) told me that the first time he did that, he plated the hole at the end, when the board was all engraved.All the trace where cover with the plating, making this big short circuit.Yes, the Xbee has greater range then bluetooth. There are some bluetooth out there that do have some very good range. 50 meter is enough. With bluetooth, you don’t need a external receiver because a lot of computers these day have bluetooth.

"claw",

"light sensor"

[David Hyman]
built this device
to control a LEGO claw. One one end of things is the part you wear, that measures movement of two fingers and your thumb. On the other end of things is a LEGO claw with three opposing digits. You move, it moves. The claw uses light sensors and a gradient strip for position feedback. There is also an up-down wrist action that uses a touch sensor as the input. This is impressive enough to give
the sniper rifle
a run for its money.

Dingoo A320 RAM Upgrade

[Stephanie]
beefed up the hardware on her Dingoo A320
. She enjoyed the features that the
A320 handheld gaming system
offered, but wanted the 64mb of RAM available in its bigger brother, the A330. A comparison of the two led her to believe a swap might be possible and after sourcing a pair of replacement chips for $12.50 she took the plunge. Once the solder had cooled it was just a matter of flashing some different firmware to take advantage of the upgrade.

If you’ve got some time to scour eBay and $500 sitting around you can
build your own liquid nitrogen plant
. [Ben Krasnow] figured it all out for you and estimates he can produce a liter of the stuff for around $1.15. The process depends on a membrane to separate nitrogen from the other materials in the air around us and a cryocooler to get the gas cold enough to condense into a liquid. Other than atmospheric air, you need to pump in electricity. About 9.6 kWh per liter… yikes! Is your
human hair solar panel
up to that?
Anyway, once you’re up and running you can
make yourself some ice cream
or possibly
save the world from oily destruction
.
[Thanks Chris]

Do only in a well ventilated area or outside where the chances of it creating an unbreathable atmosphere are low.Remember the first indication that you’re breathing in dangerous amounts of Nitrogen are that you have collapsed unconscious on the ground.",

DMX Keyboard Display

This
keyboard display
has an RGB LED for each key that is addressable through the common stage lighting protocol, DMX. The project video, seen after the break, does a good job of walking us through the concept. By using a MIDI to DMX converter box [John] can show MIDI signals coming from a keyboard on the appropriate key of the display. By further monkeying with the firmware in the converter box he shows a plasma effect on the whole keyboard, making the corresponding light for each pressed key pop out in bright white. Jump to about 3:45 to hear and see “Sweet Child o’ Mine”.
This isn’t the first time [John’s] been caught with a slew of blinking lights. He helped create the
giant LED Christmas tree
that brightened up our holiday.

[Daniel Daigle] is
developing a rotary display
that uses persistence of vision to graph data. The hardware he used includes a spinning head from a VCR, some LEDs, and a timing circuit to display 360 degrees of data. His timing input uses a waveform so this will work with any application where you can generate a PWM signal.
Check out his videos after the break that demonstrate a graph with a single line and another with six display lines.

(mini)How-To: Refill Your DTG Inks

The number one and number two things asked after presentation of our
DIYDTG
were…
“How does it hold up in the wash?”
and…
“How did you change out the inks?”
While we’ve explained the first several times (regular ink washes out, DTG ink gets a little lighter but survives) we can hopefully answer the second with a tutorial.
To change out or refill the Epson cartridges we used was relatively simple. You’ll need a few supplies.
-Old/used (or new, but you would be wasting ink) Epson cartridge
-DTG ink (we recommend
DTGinks.com
)
–
SSC utility
(this lets your trick the printer into thinking it has a fresh cartridge)
-Windex (ammonia base won’t rust the print head)
-Plastic syringe
-Flat head screw driver
-Hot glue
-Electrical tape
-Small cup
-Rags (ink gets everywhere)
-Resolve or other stain remover (to clean up said ink everywhere)
-Time (a lot of it)
-(Optional) sponge from other printers
-(Optional) latex gloves
-Original head waste collection piece from printer.
The bottom item on the list is a small funnel and squeegee that were originally located just below the head when it is at ‘home’ position within your printer. Its job was to suck ink out of the head, cleaning it and priming it at the same time.
Fair warning, your fingers will be black/stained without gloves.
You’ll want to first take the flat head screwdriver and crack open the cartridge’s top. Make sure it stays intact, we will be reusing it and glueing it back on. From there, pull out the old sponge that resides in the cartridge.
Pour some Windex in a cup and place in the cartridge and top. You can either soak the original sponge as well in the cup, or cut a new sponge. We don’t recommend kitchen sponges (too many large holes), but we found several clean sponges in old printer’s ‘ink recycle receptacle’ – for lack of a better term.
Let it soak (we recommend overnight).
I’ll take this moment to explain how to prime your head. You’ll want to make sure you put in some cartridge: ink, DTG ink, Windex, or other. Just don’t try to prime your head with air/no cartridge!
Take your syringe, and push it onto the hose that is connected to the waste collection piece.
You’ll position it below the head’s nozzles (seen in the picture below as dots), push it against the head with one hand. Using your other hand, pull out the syringe (creating a vacuum). You should get a nice thick stream of whatever cartridge you put in. If not, wiggle around the waste collection piece until a seal is formed. We pull out on average about 1ml of liquid to prime.
(Optional) If you think your printer has a lot of clogged heads, you can take out the cartridge from the cup. Place it in your printer head, and fill it with Windex. Prime as explained above. Your heads should be clean and clear.
Once your sponge has soaked (or you cut a new one), simply drop ink/DTG ink onto the end of the sponge that will be pushed into the cartridge first. We used about 10ml, do NOT fill your sponge completely.
Stuff the soaked end first into the cartridge, pushing it down to the bottom, but make sure you don’t push too far, the top of the sponge has to touch the lid (why that’s important in a moment).
You’ll notice that by squashing down the sponge into the cartridge, the extra previously unfilled area of the sponge gets soaked.
Push on your lid, and hot glue around the edge, it must be air tight (but not so much so you can’t ever get the lid off again, we assume you’ll want to refill again). And place a small amount in any holes except the main center one.
By having the lid done this way (with the sponge and glue) you’re creating an air tight seal that only lets out the correct amount of ink. If you cleaned out your head before with Windex (that optional stage), with no sponge and no lid as instructed, you may have noticed just how easily without this seal that fluid will just fall out of the head, you don’t want that.
(Pictured below, ink dribbling out)
Wrap a tight piece of electrical tape over the cartridge, covering and sealing the bottom hole completely. Only once around is needed, too many and the plastic spike may not be able to pierce the tape.
Place the cartridge into the head, from here on out, until the cartridge is completely empty, do NOT remove it from the head. Prime your head. At this point if you put too much ink into the sponge you’ll see it fall out of the head (as mentioned above). Don’t worry, just leave it. Place a rag underneath and wait (once again, overnight is prefered). By morning you should be able to wipe away all the excess, prime it, and no ink will ‘just fall out’.
We also added a small piece of rag to act as a squeegee to help clean the head when it returned to home position.
You’re done! Do a lot of test printing, you’ll find that some of the first prints will be messy (it took us 10 full prints before we got it to be constant darkness).

Building A Glue Stick Flashlight

Building an LED flashlight is simple, right? Take a battery, connect it to an LED by way of a resistor. Alright wise guy, now make one that steps up the voltage for multiple LEDs and don’t use a boost-converter IC to do so.
[fede.tft] shares
a flashlight built inside of a used glue stick case
. It’s the perfect size for one AA battery (we’re always on the lookout for
good battery cases
), and a shape that we’re familiar with as a flashlight. The problem is that he wants two white LEDs but with just one AA cell he’s never going to have more that 1.5V available. He licked that problem, getting to 7.2V by designing his own step-up converter using one transistor, an inductor, and three passive components. To get the inductor he needs, a stock part is disassembled and rewound to suit. Maybe you just end up with a flashlight when all is said and done, but then again, the
Sistine Chapel
is just some paintings on a ceiling.

Linux Tablet Built Around A BeagleBoard

[Justin] shows us how to
make a Linux tablet out of a BeagleBoard
. You may remember [Justin’s] work at
liquid cooling an Arduino
. For this one he moved past the AVR hardware but took the idea of shields along for the ride. The device above is something of a Linux tablet, with a touchscreen shield on top of the
BeagleBoard
, and one below it for power. He’s selling these as kits which include the 480×272 OLED display as long as you can handle the fine-pitch soldering for those headers. We’re not sure our hands are steady enough for the challenge.

Who need’s a touch screen when you’ve got 800 inputs each backlit with an RGB LED? This impressive controller was built by Ander for use in his performances. He did it with the intent to get rid of the computer monitor in his setup. We think there’s something to be said about that. It seems weird to go to a performance and see the artist staring at a screen the whole time. Unfortunately we don’t have too many details about the hardware but we can tell you that he’s using
Ableton Live
on the software side of things.

It looks like he’s just mapped physical controls to all of the on-screen buttons. Here’s a general example:http://macmusica.files.wordpress.com/2009/03/ableton-live.jpegEach of the little rectangular buttons at the top triggers a loop or sample which can be set, quantized, and distorted in any way. They are organized horizontally into channels(columns).The other rotary encoders are ‘sends’ to determine how much of each channel goes through effects loops, pan, and volume. Next to each of the channel meters there are Solo/Mute buttons and below that there are Pre/post Fader Listen(cue) buttons.It’s a very simple but powerful program, and it’s also very simple to map to a MIDI device(great LEARN feature) of any size, shape, or sort. This controller is hands-down the coolest thing I’ve ever seen it connected to.",

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.
This
Wiimote Rubens’ tube
caught our eye. A
PVC
Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

Cockroach Pimps A Sweet Ride

] |
This giant Madagascar hissing cockroach rides proudly atop his three-wheeled robotic platform. This project from several years ago is new to us and our reaction to the video after the break is mixed. We find ourselves creeped out, delighted, amazed, and saddened.
The
cockroach controlled robot
uses a trackball type input. A ping-pong ball is spun by a cockroach perched on top. The lucky or tortured (depending on how you look at it) little bug has an array of lights in front of it that illuminate when obstacles are in front of the robot. The roach’s natural aversion to light should make it move its legs away from that part of the display, thereby moving the robot away from the obstruction.
We’ve seen some bio-hacking in the past. There were
robots that run off of rat brain cells
and
remote controlled beetles
. But none of these projects make us want to get into this type of experimentation. How about you?

That distance sensor light-array “immersion” setup does not seem to work very well.B.) We learn/are told nothing about the cockroach’s response to the stimuli independent of the robotic platform. A more useful starting point would be a virtual environment feeding the array, with some mechanism of determining whether the cockroach was reacting to the array in the way that the researcher hypothesized. If I remember correctly from biology cockroaches have far more senses than vision, and the huge assumption in this project is that the cockroach will react primarily to the display and not other environmental factors.I like the concept, but wish that the project was executed/explained in a stronger manner. It’s like Skinner without training, trying to piggyback on natural response.http://en.wikipedia.org/wiki/Project_Pigeon",

Now if the robot had a uC deciding when to run the lazy() routine, that would be more interesting to me.We know that living things can control robots; we’ve built ROVs that dive to the depths of our oceans, diffuse explosives, and go to mars. Hell we’ve even trained monkeys and other animals to control robotic arms and the like.I do like how the guy essentially augmented the roach’s sense of sight, and it would be more interesting if that wasn’t the roach’s only sense.Sure it’s neat, but this doesn’t seem that significantly different than me controlling my 2 ton vehicle on a daily basis. Sure I may have higher cognitive abilities, and a different way of sensing than the roach, but it’s a very similar concept.",

Antennae are *very* complex sensory devices relying not only on touch but also chemical sensing, changes in air currents, and vibrations to do their jobs. I highly doubt the roach is capable of true “disorientation” but perhaps it is missing a facet of its normal locomotion…its worth noting that they often lose their antennae anyway, by the end of their lives, so they are more accessory sensory organs than necessary ones.Chapter 12 in Entomology by Gillott might be of interest to you, though, Joe.",

Reader [Osgeld] is a board-layout ninja. He populated this 4×4 LED matrix board without having a layout plan to start with.
Watch it develop in slideshow format
to see the art work he performs. The display is driven by a shift-register and he’s included all the proper parts like resistors and transistors, yet he makes everything fit. Why is this amazing? He’s using uninsulated wire and not a single one of them crosses another wire. He’s physically designing a printed circuit board, routing the traces as he solders away. He’s built this to use with
an Arduino shift register tutorial
and our only question is where is the header to hook this board to a microcontroller?

In today’s age of affordable good CAD (eg Eagle) and cheap laser printers there’s no good reason to not etch a board. I prototype by etching and laying down SMDs. It’s quicker, easier and generally cheaper than dealing with through-hole components, and you have the advantage that you can more easily reuse components too.

And then seeing tube projects and thinking it was all too free form for me.Fast forward to breathing lead solder fumes for days at a time and wiring up projects just like this… I wasted hours building enormous collections of gates, counters and LEDs and then running them like light shows… which took me back to building light show boxes…Which led to accidentally becoming a DJ and directly resulting with the chance to commence sleeping with a score* of attractive but not very bright girls… all of whom eventually realized that not every DJ is a party animal worth keeping around.So kids, a word to the wise:Knowing your way around a soldering iron can do wonders for your social life. Just make sure you read the MSDS on serial dating first. Especially the parts about vector multiplication and the least common denominators. Ah, innocence.* Speaking of scores (a score is 21), I should probably send a fat envelope of cash to Giorgio Moroder.

Pressurized PVC Water Gun

] |
Hackaday’s [Caleb Kraft] has branded today “kiddie d-day” after seeing this
PVC water gun
follow close on the heals of the
LEGO sniper rifle
. This is a great summer project if you don’t mind letting the kids use the quick connect on your air compressor. It’s really just a ‘T’ made of PVC with two valves for air and water management and a soda bottle on the third leg as a reservoir. In the short clip after the break you can see that you don’t get a lot of shooting time out of each charge compared to
the DIY Super Soaker
, but this build is also a lot less complicated.

"content": "@Harvie.CZIf the bottle is mostly full of water, it’s not going to explode but rather crack and leak out.Water isn’t compressible, but air is and will act like a spring:If you pump a bottle full of air, it will probably explode and send shrapnel everywhere since the air compresses inside. However, pumping a bottle full of water is relatively safe because the only springiness in the system comes from the plastic stretching.One of the applications of this is used in making 2-stroke exhaust pipes in a process called hydroforming. You sandwich two pieces of thin sheet metal, weld them, add a water connector, and pump the assembly full of water. The vessel fills with water and deforms into a metal “bag”. Cut off the ends and you have an exhaust pipe!A single pinhole leak in a system full of water will safely depressurize everything.Example:http://i49.tinypic.com/20jfx9e.jpghttp://i50.tinypic.com/2j137m0.jpghttp://i45.tinypic.com/jii7wi.jpg",

For the purposes of making a portable water gun, you probably would be quite happy with a max pressure of say 45psi, which stuffs about 6 liters of air volume into a 2 liter bottle. If you use one bottle for water and one for air, you’d be able to move 2 liters of water with a little headroom left over. Please be smart, start small, and work up to a safe maximum.

intelligent battery charging circuit
. Instead of blindly charging your battery into oblivion, this one shuts off once the battery is fully charged. It is a nice clean circuit that can be adjusted and fine tuned to your specific needs via some trim pots and dip switches.

Also, BMS’s have a built-in “time-and-number-of-charges” counter that tells You that “battery is bad” (programmed obsolescence” , as we know It.",

This kills the batteries fast if the laptops are left plugged in after their batteries are fully charged. I was just saying that a more intelligent approach to this is needed in most laptops. I’ve seen IBM laptops that at least beep once the battery is fully charged. This circuit will not help with that though. I was making a general statement about other areas that need improvement.",

Doing a simple float charge design like this one could take a long time depending on the capacity of the battery, however it is fairly cheap.A faster charger version would charge to about 14.5-14.7V, and then switch to a float charge of about 13.8V once the current reaches a certain low threshold. There’s tons of designs like this, just go look online. Fairly simple and cheap.Other chemistry types require very different charge profiles. Most laptop batteries(lithium ion) for example, require a constant current constant voltage charge profile, and has to be sensed with fair precision. Overcharging can destroy the battery as well as be dangerous.Someone needs to look into Nickle Iron batteries again… Edison did them back in the day, and they are very interesting…",

Minifigs beware, something’s afoot. This LEGO sniper rifle is in talented hands to clean up those problem areas. [Jack Streat] put together
this fascinating build
as well as the delightful demo after the break. The bolt pulls a 1×4 block out of the eight-round magazine and loads it into the chamber. A pull of the trigger flings it with surprising accuracy. Want to be the coolest parent ever? Forgo the store-bought toys this year and put one of these together for your kid. Just don’t turn them into
Private Pyle (NSFW)

The other end would stick up inside the ship, and you’d fire the gun by pushing it down so the rubber bands shot the block out of the same opening you used to push it in.The tension in the rubber bands put so much stress on the gun’s structure that they had to be built as a part of the ship hull. When the ships sustained enough damage, they would explode and fly apart. The guns, or torpedo shooters, were powerful enough to break the other ship in half with a well aimed shot anyways.",

[Alex] had an old FM radio tuner card come his way. It used an
ISA connector
, a standard that went the way of the dodo in the mid-nineties. With the challenge of implementing an ISA-bus to configure the card he set out on his mission.
What he came up
with is a working radio using the ISA card and driven by a PIC 16F877. Join us after the break for schematic, code, and a few details.
The card is based on an LM7000 PLL synthesizer paired with a LC7534 tone/volume controller. With a bit of datasheet study [Alex] figured out where the data pins for the chips map to the ISA bus. Working with a prototyping board, the hardest part turned out to be finding the addresses for the chips. He ended up testing all 256 possibilities and watching for the data to be latched from the ISA bus. Alex says the hardware is capable of tuning from about 60MHz up to 125MHz.
We asked him if he’d share his code and schematic. He came through with both, and kudos to him for such a clean hand-drawn schematic. Nice work [Alex]!

Take a few moments and browse this

. Tasked with the job of preserving the roughly 150 million historical items, they are constantly developing new methods using bleeding edge technology. There is an odd balance of some of the oldest documents in tandem with some of the newest technology evident in these pictures. From doing spectral scans of ancient books to laser mapping warped phonographs, everything must be preserved and documented.
