[Chris Harrison] and [Scott E. Hudson] have built a novel system for
faking a 3D video chat session
. Their implementation separates the image of the chat participant from the background. They then dynamically reposition the video based on the movement of the viewers head. Their using the OpenCV library to do facial recognition (just like the
Laughing Man demo
). The 3D effect is very similar to what you see in [Johnny Lee]’s
Wiimote headtracking
. A video of the pseudo 3D chat is embedded below.

With the proliferation of built in webcams on laptops, netbooks, UMPCs and all kinds of other shit that has Internet, its not too much of a stretch to ask for TWO webcams, on either side. They are pretty cheap!(The webcams)Theoretically, you can use the above technology, and a well written, Skype, MSN or more professional video conference clone, to take the two images, use the ideas above and get a TRUE three-dimensional picture that is not affected by the things that mr. gabreil talked about (when the background changes).I would like to see this happen, i think it would be very cool. Also there is the problem, of when (in this first iteration) when u move the camera view, there is black space which looks really unpro.All in all its a cool idea, that probably could be marketed if you where able to make the software above, remove the bugs and got the appropriate hardware. im thinking two webcams cannabilised into one piece of plastic, with an incorporated USB-Hub i order to have only one usb cable for the end user.This shit could sell, and also be super cool, and revolusionise the way we video conference.(to say nothing of “other” webcam activities that we may or may not engage in).",

We’ve been following
Boxee
(not
Boxxy
) since its
public alpha debut last Summer
. We were captivated by it. Who expected a project built off of code originally intended for
hacked Xboxes
would be
shown on NBC’s Today Show
? We’ve been promised internet connected set top boxes for years, but it seems like Boxee is here to stay for two solid reasons: 1. It’s free. 2. Major content providers have finally figured out how to publish online and
Boxee
supports them. You can replace your network television with on demand content from Hulu, ABC, and the like.
One of the most affordable platforms currently supported by Boxee is the
Apple TV
. Lifehacker has a guide for
installing Boxee on an Apple TV
. You prepare a
USB flash drive
that is then used to patch the stock firmware. Once installed you can take advantage fun features like downloading torrents directly to the box.

[Alanson Sample] and [Joshua R. Smith] have been experimenting with
wireless power transfer for their sensing platform
. Their microcontroller of choice is the MSP430, which we used on our
e-paper clock
. They chose it specifically for its ability to work with low voltages and they discus its specific behavior at different voltages. The first portion of their paper uses a UHF
RFID
reader to transmit to the sensor’s four stage charge pump. They added a supercap to provide enough power for 24 hours of logging while the node isn’t near a reader. For the second half of the paper, they use a UHF antenna designed for digital TV with the same circuit and pointed it at a television tower ~4.1km away. It had an open circuit voltage of 5.0V and 0.7V across an 8KOhm load, which works out to be 60uW of power. They connected this to the AAA battery terminals of the thermometer/hygrometer pictured above. It worked without issue. The thermometer’s draw on a lab power supply was 25uA at 1.5V.
It’s an interesting approach to powering devices. Do you have an application that needs something like this? For more on wireless power, checkout this earlier post on
scratch building RFID tags

Digital modes sadly tend to have “ringy” harmonics in conversion applications. Which can quickly become parasitics and worse still rebroadcast on unwanted frequencies. With very potentially bad results. But to keep on the original post’s track requires less heavy math and just a few simple mnemonic style rules. Up Frequencies down lengths. The old term “Wavelength” literally embedded the concept. MF to HF waves are in Hundreds to Tens of Meter resonant lengths-absent of course coil loadings or fractional wavelength antennas. Bear with me for a moment as it’s really to a point worth exploring. VHF to UHF Bands “6 meters to the centimeter bands” are then resonant at those lengths. Making elements shorter as is seemingly obvious. The trade offs? At the 1 MHZ or so of that Chicago radio station coupling in a magnetic field mode over short distances is the dominant mode. At the UHF or centimeter wave ranges you shift modes into the distant E field mode/s for simplification. Which produces a slightly “looser” coupling. Hey- I’m trying to dredge up memories of RF lectures heard at age 15 or so:>How the hell does this link to a hack article? Well- understanding the concepts makes building this stuff easier for me at least. The wrapup of all my seeming ramble is? Think of the RF sources you are “Harvesting” energy from as the “Primary” of a switch mode power supply! Albeit one with a non-trivial air gap between the primary element and your secondary coil on… So the induced RF voltages get rectified and either directly used or could feed other up converters as in the original post. Where this is leading? Depending on the field energies ion any given situation multiple energy harvesters on multiple frequencies could harvest energy and sum their outputs just as the cells of a solar panel do…",

We’ve all dreamt, with tears in our eyes, of one day flying with a jet pack. The inherent danger of falling and/or exploding were almost as much as of a deterrent as the price tag. Now, that dream is closer to our grasp. This system, looks like it is
basically just a pump that drags along behind you
pushing water through nozzles on your back. You can see a
video of someone flying around on one
here. We think that the theme song should actually come with the unit and be broadcast at all times.

The
Segwii is a self balancing robot
. Yes, another one, only this one can be controlled via WiiMote. The Segwii can function in stand alone mode, which offers only the ability to balance, or it can be tethered. When tethered via USB to the laptop, it can be remotely controlled using the WiiMote through processing. Sadly, the video above doesn’t show any WiiMote action. Lets hope they continue the work to incorporate a direct bluetooth connection to the bot.
This one seems to be pretty sturdy, though he does mention that temperature changes can throw off the internal gyroscope. This one seems to be similar to the
Arduway
in terms of how smoothly it keeps balance. The
miniature balancing robot
has them both beat for pure goofyness though.

LED Push Buttons

Caleb Kraft

"LED Hacks",

[
"button",
"led"
] |
[pros] has come up with a
very elegant way of making lighted buttons
(
translated
). Using a bunch of small push buttons harvested from old CD players, he rigged this unique way of mounting LEDs. Each LED has two buttons under it. They are wired in parallel, so if either of them is pushed, the button works. The LED isn’t actually soldered where it passes through the board. The anode and cathode are bent around and soldered to allow the LED a little bit of travel. There’s a good picture of how he did this on the site. The rest of the details might be hard to decipher though, it looks to be in dutch.
[thanks Tom]

"content": "rasz: I can only assume you don’t have a degree in mechanical engineering, so I won’t blame you for a little ignorance.LED legs are usually made (mostly) of iron, and iron is one of the materials that has a so-called “fatigue limit”, unlike, for example, aluminium.If you stay below this stress level, the material will never fail due to metal fatigue. This is called the infinite life concept.Now I don’t feel like calculating the stresses in the legs of the LEDs, but with a very small travel (say, 2mm) and the length and shape of the legs in this example, I think they are well below the fatigue limit.The only thing I would worry about, are the brittle solder joints.",

Then, instead of using the remaining leads from the LED to connect to the solder point, you simply use a small length of thin wire. This setup would still function properly with no fear of stress on the solder point, although the LED might jiggle around more than you want.",

The last time we checked in on Pandora it was just being
shown in dev unit form
. Embedded above is a video of the first case prototype. It doesn’t have any components yet, but it definitely looks like a good formfactor with a lot of potential. The
Pandora
is a
Linux
based portable game console with an 800×480 touchscreen.

Ruin & Wesen are a two person shop creating specialized music gear. As part of their recent MIDI Command development, they got into case manufacturing. They purchased a mini
CNC
mill to cut the aluminum cases. Unhappy with the software options provide [Wesen] decided to
write his own G-code generator
.
G-code
is part of the numerical control used to command CNC machines. He implemented his interpreter using the language he’s most familiar with: Common Lisp (not surprising if you notice the
website’s backend
). The post covers the design philosophy used and some of the problems that came up. We look forward to future releases since the interpreter can generate milling code using processing.org sketches and cut PCBs directly from Eagle.
You may remember Ruin & Wesen from when they shared their
Eagle layout videos
.

[les robots] had a defective
Eye-Fi
card on his hands and when a replacement was sent, he was told to destroy the original. What better way to ‘destroy’ something than opening the case? The
Eye-Fi
is an SD card with a builtin WiFi radio so it can upload images while remaining in camera. One
version
uses Skyhook’s location service to geotag photos. You can see a few photos of the
dismantled card on Flickr
. The board is manufactured by Wintec. The wireless side is handled by Atheros’ ROCm, the same low power Radio-on-Chip module you would find in a mobile phone. The flash memory comes from Samsung and the antenna is
along the back edge
, where it has the best chance of getting signal.

No way round this one guys – except to hack into the HAL (layer) and modify the Tx db/dbm level. Possible? – yes, but well beyond the average user skill level.None the less a cool product – which could offer real world usable genuine 100meter plus radius download distance (indoors) if manufactured with a 900Mhz rf front end – could be used with Ubiquiti networks 900MHz wireless cards. 900Mhz Ub router card with external antenna – just think of the uses!",

Wireless Genesis Controller For PC

[Jacob] wanted to play some sega games on his PC and felt like the experience just wasn’t complete while using the keyboard for input. He had an old MadCatz controller laying around, which could have probably been connected fairly simply, but he really wanted it to be wireless. A wireless keyboard was sacrificed, and the
wireless genesis controller was born
. To make it, he disassembled the keyboard to take the controller chip out. After tracing out and soldering switches to the leads, he installed it in his genesis controller.

[PunMaster] wrote in to tell us that he has just released the first public demo of
FiSSION Project
. It’s a homebrew 3D game engine for the
Wii
. He’s hoping it will make development easier for other people that want to get into the Wii hacking scene. The project was originally spun out of similar work he was doing targeted at XNA for the
360
. This is just a demo to generate interest in the project and hopefully get some feedback as to what’s needed to make a full release possible.

"content": "@tonyFiSSION runs through the Homebrew Channel (as seen in the video). This means that it runs as a full-power executable program, the same as a store-purchased game does. It is not running under a web browser or any other “virtual environment”. It is real application code just like any official Wii application. The only difference is that my applications requires a modded, Homebrew Channel installed, Wii (because my code is not signed by Nintendo).If you don’t have a modded wii already, seehttp://wiibrew.org/wiki/Setting_up_your_Wii_for_Homebrewfor instructions.In a nutshell, FiSSION works by loading 3d objects and textures from a memory card, decompressing them, putting them into the Wii’s memory, and telling the video card in the Wii to draw them. Then it receives input from a usb mouse and keyboard to allow the user to change their viewpoint.I am using devkitppc, a c++ compiler / toolkit for the Wii, to build my applications. See the tutorials on wiibrew for more information on how to get started using devkitppc to build your own homebrew apps.For your convenience, here’s the link:http://wiibrew.org/wiki/Getting_Started_with_devkitppc.I eventually plan on releasing the full source code for FiSSION, but not immediately. I want to develop it a little more before I let the world dig their claws into it.The game content (the actual objects and graphics that the engine is loading) has been converted from files taken from from Bungie’s Halo. I used them because I didn’t have anything original made yet (and because I’m not the best at modeling). Please (please!) note though: this is not by any means a port of Halo. It is an original game engine that I am demoing using objects taken from Halo. As soon as I make some new levels, all traces of Halo will be gone from FiSSION permanently. I’m not going to go into the details of model / map creation, but if you’re interested, google the keyword “blender”.Well I hope that clears things up. Glad to see you liked it. :) See ya.",

In fact, I am currently working on a set of game / level development tools that will work in conjunction with blender for the creation of FiSSION content. Likewise, FiSSION is not by any means an abandoned project. I have been actively working on it whenever possible, and have certainly made some decent progress since the first release. Still, I have some pretty high goals (and a lot of tedious coding) between me and my next planned release, so it might be a few weeks or more before you see anything new. Either way, check back often, and have fun. :)P.S. A few kind, encouraging emails might be enough to make me at least post a few very preliminary screenshots of the dev app. Seehttp://www.electroworks.net/fission/public-demo-v001-readme.pdfand your local base64 decoder for details. :P",

I am hoping to eventually write a custom export plugin for blender that pulls out additional information that could be useful to the editor / engine.

Gizmodo has done us all a favor by wading through many forum posts and condensing them into a handy guide to
installing Ubuntu on your Playstation 3
. It covers some of the caveats of going this route. You have to backup all of your game data before starting since the system repartitions the drive. Ubuntu installs without any problem, but because the cell processor is a PowerPC architecture it means not everything has been ported to it. There are a few things you need to install to get the Sixaxis controller to be recognized as a joystick. Super Nintendo emulator SNES9X is available and works, mostly. It doesn’t support fullscreen and cries if you reconfigure the buttons.
Supporting developers through alternate operating systems isn’t new to Sony. With the original Playstation, they released
Net Yaroze
, a consumer grade dev kit. The Playstation 2 was the first time they
officially supported Linux
on a game console (our first Linux machine). The ground breaking thing about the Playstation 3 was bundling in Linux support with every single console; no specialized hardware needed. Unfortunately they’re not near as open with the
PSP
.

Until relatively recently, a PS3 was about the same price (or cheaper) than a comparable nvidia card that could run CUDA — where the nvidia cards could have more memory, but the ps3’s could scale better in terms of clustering large units cheaply — for an NVIDIA cluster, you need a host machine for however many video cards you connect in SLI, increasing the cost.i think that it’s probably cheaper these days to go the CUDA route (for computing problems that are particularly suitable to these simd architectures), but i think the new cell processor that’s coming out (probably not in the ps3’s) might change some of that?",

[doctek] wants to help ease any fear you may have of surface mount design. He has written this
extremely in depth explanation
of how to design and build an LED driver composed of surface mount parts. While there has been plenty of surface mount instruction floating around for a while, he feels that they skimp on the details, especially when it comes to really tiny parts who’s pads are unreachable with a soldering iron. The method he uses is the “hot plate” method
we’ve seen before
. There’s enough information to build your own tiny LED driver with pulse width modulation, as well as tons of references to explain how and why he does things the way he does. Great job [doctek].
If you’re going to be doing a lot of soldering, you should check out our
soldering station how to

AVR Light Controller

[Matthias] sent us this project where he
builds an AVR light controller
. He had a halogen bike light laying around, but was unsatisfied with its lead-acid battery. He wanted to use a lithium-polymer battery but found that they can’t be used directly with halogen lamps due to their voltage. His produced 8.5 volts at full charge and can’t be discharged to below 5 volts. He new a power controller would be necessary to try to flatten that out for his lamp, which needed to stay between 6-12 volts.
He used an ATtiny45 doing
PWM
to change the voltage. Some other cool features he added were the high and low settings and an LED status light for warnings. You can find pictures, schematics and source code on his page as well as tons of great information. Great job [Matthias].

The damn thing would be super thin, but put out a blinding amount of light. Granted the battery life would be crap, so you would need to keep it charged all the time, but it would be impressive to see something so small put out so much light, even for a few minutes.

Tired of having to physically connect to your microprocessor to upload new code? Just do it
over a wireless connection
. [Nathan] takes us through the process of setting up a wireless bootloader for the ATmega168. He is using the XBee base and remote modules for the
wireless communication
. While people have been doing wireless bootloading with the Arduino already, [Nathan] found that it was common for them to have timeout issues. His remedy was to make his own custom one that is much faster. He’s asking for help though. At this point it is tested and working, but he needs someone with more programming knowledge to help him make it “drop-in” compatible with the Arduino IDE.

5 Cent Tilt Sensor

This is a 5 cent tilt sensor. We know it cost more than 5 cents, but it is in fact a
tilt sensor that utilizes a 5 cent coin
. We’ve all done quick hacks to make quick sensors for various projects. We’ve seen tons of them, from stealing springs out of pens and shoving a resistor through them for flexible contact switches, to tin foil touch sensors. This one is new to us though. The design is fairly simple, you insert 4 bits of wire to serve as contacts and the coin will make contact with only two at a time. It isn’t analog, it isn’t extremely precise, but it is super quick and easy. Thanks for sharing [ix].

It seems like every piece of hardware has to earn its respect by going through some standard paces. One of which is having
Quake
ported to it. Much like an angel earning their wings,
Bug Labs
, with the help of community [CMW], has ported
Quake
to the
BUG
. Right now, the only add on needed is the BugView module. Controls are done through the base unit.

Thermosonic Wedge Bonding

] |
In the past, if we’ve been doing smd soldering, we’ve used pretty basic
hot plates
. This project takes that idea a bit further. Since [kc6qhp] will be using parts that aren’t conducive to soldering, he has to use
wire bonding
. After locating a fairly cheap wire bonding machine and microscope, he
built the heated stage to fit perfectly with his other tools
. You’ll notice that he has machined a lip around the heat plate for small custom C-clamps as well as made it adjustable height. Very nice work [kc6qhp].

It came with no wire spool, no clamps, etc. The bond parameters (time and power) are set up for only a single setting, whereas I may need two settings for first and second bond (MMIC and then substrate). So I’m going to make a controller to set those. As far as bond pressure goes, I’m calibrating with a small pocket scale, and using just maybe 10-20 grams of force, 200 to 500 ms long. Now the big uncertainty I have is with respect to power. Apparently this unit has a ~20 watt transducer, but I have no idea what units the setting is in. Do you know of a way to measure that? Or even to extrapolate from electrical measurements?Also, I’m not sure if my unit is phase locked, is that a critical feature?Finally… I’m planning (obviously) on heating up the part to 150 C and then bonding with cold wire. Westbond typically heats their wire before bonding, how critical is this?I’ve made some cold bonds on a piece of alumina substarte and had mixed results depending on the settings. Some come out perfectly, others result in a sheared tail, and others just don’t get good adhesion. I think its going to be a matter of refinement to get these to work well, but hopefully adding heat will help.I’m using Gaiser Tool wedges, made from tungsten carbide (I believe) and the slightly concave tip as reccomended for gold.",

Not content with
Nintendo’s
current portable video game offerings, fifteen year old hardware hacker [
Xteaphn
] (pronounced “Steven”) has come up with a series of hardware modifications to make a battery-operated
Wii
console. The hacked console features a folding laptop-like screen, which apparently includes the IR emitters necessary to make the Wiimote operate properly, as well as a set of tiny stereo speakers. To show how tiny the modified console is, [Xteaphn] provides size comparisons with thirteen- and fifteen-inch
laptops
as well as with a classic Nintendo Game Boy. The only potential hindrance to its long-term durability, as best as we can tell from the video, is that the battery pack and its associated connecting wires hang crudely off the back of the console like a sort of electric colostomy bag.
Check out [Xteaphn]’s YouTube video after the break.

Sweat Bot

[
"Robots Hacks"

[] |
The future is here ladies and gentlemen, robots are truly making our lives better. The grueling job of sweating into clothing has been taken over by the latest in technology:
the sweat bot
. With water heated fake skin, and robotic sweat glands, this machine works tirelessly to test clothing. While emulating walking or jogging, it sweats into the clothing. This helps in the design of more breathable and sweat resistant fabrics. Though we know it is just a machine, choosing to put the water hoses through its face was just plain creepy.

[ladyada] has republished an interesting snippet from the synthDIY mailing list. [David Dixon] discusses the actual chemistry behind
ferric chloride based home circuit board etching
. He concludes that ferric chloride is essentially a ‘one-shot’ oxidant. It can’t be regenerated and can be difficult to dispose of properly. The use of acidified copper chloride is a much better path and becomes more effective with each use, as long as you keep it aerated and top up the acidity from time to time. This etchant solution is actually the result of initially using hydrogen peroxide as an oxidant along with muriatic acid. You can see us using this solution in our
etching how-to
and while
creating the board for our RGB lock
. For more information on using hydrogen peroxide, check out
[Adam Seychell]’s guide
and
this Instructable
.
Aside: [ladyada] has added the
receiver code
to the Wattcher project page.

Here’s an odd little footnote we found while perusing the
Comic Tools blog
. [Matt Bernier]’s blog is dedicated to drawing and inking tutorials for comic artists. He uses a lot of example photographs that involve both hands. This week, at the bottom of his post on
cleaning brushes
, he included a photo to illustrate how he takes all of these point of view shots. The camera is strapped securely to his head using an old lanyard. He can see the display and access the controls on the back. After composing his shot, he just sets the timer, and you get a picture of what the process looks like from his perspective. Sure, it looks silly from this angle, but it really helps out the posts.

As a followup to last week’s post on
automated protocol analysis
, [Tod Beardsley] has written up how to start
analyzing a protocol manually
. He walks through several examples to show how to pull out the interesting bits in binary protocols. His first step was sending 10 identical select statements and capturing the outbound packets. He used the Ruby library
PacketFu
to help with the identification. It compared the ten packets and highlighted one byte that was incrementing by four with each packet, probably a counter. Looking at the response indicated a few other bytes that were also incrementing at the same rate, but at different values. Running the same query on two different days turned up what could be a timestamp. Using two different queries helped identify which byte was responsible for the statement length. While you may not find yourself buried in HEX on a daily basis, the post provides good coverage of how to think critically about it.

Road Sign Hacking

We’ve all seen these on the side of the road and wondered
how we could change the message
. It turns out that it is actually pretty easy. There’s a keypad inside for programming that is often still set with a default password of “DOTS”. Even if the password has been changed, you can reset it right there pretty quickly. We shouldn’t even need to warn you that it is illegal to tamper with these, so unless there really are zombies ahead, you probably shouldn’t mess with it.

"content": "I’m a frequent reader of this website and absolutely love it…but you know, as an employee of a state Department of Transportation, having worked in Construction all last summer, I’d really, REALLY, like to advise would-be hackers to NOT mess with these signs. Let me explain.Drivers are really, really, really damn stupid. Besides Construction, I’ve also worked on plans for traffic control and notification and we throw every freaking thing imaginable, short of a personal attendant for every vehicle driving through a construction zone, to alert drivers to construction and detours…more than you’d think simply don’t pay attention and then get pissed at US because they don’t know what’s going on. Furthermore, those signs are used to warn drivers about work being done, especially when the work is not behind protective barriers. When you’re standing next to live traffic running at 70MPH and the only thing separating you from the Almighty is the driver not being a dumbass, you’d have a much bigger appreciation for PCMS (portable changeable message signs) locations warning people about your ass out on the jobsite. In addition, PCMS warn drivers about changing road conditions or detours. Many drivers on interstates aren’t familiar with the areas, and those smart enough to actually read the signs need PCMS messages to let them know about a traffic shift or a detour. Have you ever seen an 18 wheeler accidentally trapped in a residential area? What about one that’s trapped in a downtown grid because traffic is moving one way and the area is too narrow and not tall enough to accommodate the truck and trailer, during morning rush hour? I have, and it’s not fun to deal with.There is no other hack I’m aware of chronicled on this webpage that runs the risk of putting anyone in danger except the person doing the hack themselves…this hack, however, could result in fatalities, and I’m not being the slightest bit over-exaggerative. Please don’t mess around with PCMS!",

A leyden jar is basically just a simple home made capacitor. We’ve
shown you
how to make them before. This, however, is how you
make a ridiculously large one
. [Nickademuss] used a five gallon bucket to make his leyden jar. That’s five whole gallons of lightning. The video, which you can see after the break, shows it light up the entire room when it lets out a fairly formidable spark. This is dangerous folks, be careful.

MegaUpload Captcha Cracking In JavaScript

This was certainly the last thing we expected to see today. [ShaunF] has created a Greasemonkey script to
bypass the captcha on filehosting site Megaupload
. It uses a
neural network
in JavaScript to do all of the OCR work. It will auto submit and start downloading too. It’s quite a clever hack and is certainly helped by the simple 3 character captcha the site employs. Attempting to do the
same thing with ReCAPTCHA
has proven much more difficult.
UPDATE:
[John Resig] explained of
how it works
.

A normalised cross correlation filter could do the job just as easy.I have to say, ShaunF’s little neural network code is pretty cool. However, I can see a couple of problems with the neural network approach.Neural networks need a training data set (eg. the Megaupload’s captcha images) in order to pre-calculate the weights required for image recognition.Its classification reliability will be heavily dependent on the choice of training data. Basically there is a danger of over training, or the neural net becoming too specialised for a particular training data set. In such cases, it would be easy to defeat the neural network by simply changing the CAPTCHA images in a significant way. Realistically speaking, it doesn’t take much effort to change a CAPTCHA font – for example.Also, neural networks trained with a much broader data set will have more false positives and false negatives during recognition. Very fiddly.Anyone hoping to break Recaptcha in a similar way will have to wait for a few more decades, I’m afraid.",

The fine folks at Midnight Research Labs have put together a new toy for you to play with. It’s a Python script that makes your
WiFi hardware behave more like a theremin
. Based on the pyaudio library it monitors the signal strength of the AP you’re connected to and changes the tone accordingly. There’s a sample embedded above (
direct link
). If you have a second interface, you can use it to modulate the volume. It’s an interesting trick, but they say that there’s enough latency that it would be hard to play actual music with it.

We’ve covered a couple of different ways of doing choreographed Christmas lights. The most basic being
sound activated ones made from speakers
, then the
parallax controlled ones
. This one uses the parallax microcontroller as well, but [prabbit22m] seems to have put some more effort into the
construction and enclosure
. The lights are all LED this time around and there are 18 outlets that can be individually controlled in a nice, safe enclosure. The choreography was done well too. The capabilities video is pretty impressive, it looks like he has managed to do some fading in and out. You can see it after the break.

Adding Right Click To A Macbook Pro

Surprisingly, one of the most common complaints we hear from people trying out macs are the fact that there isn’t a right click. The latest version, the unibody, has an option that remedies this, but older versions are stuck without. While you could always plug a USB mouse in, that is hardly a hacker’s solution. [spiritplumber] sent us this mod he did,
adding right click functionality to his Macbook Pro
. It is worth noting that this is meant for the 2006 to 2008 version of the Macbook Pro. You’re on your own for different ones.
[spiritplumber] points out that there are test points on the back of the track pad that emulate certain events. One of wich, just happens to be a right click. He shows us how to wire this, to a home made contact button under the right corner of the track pad. This can be potentially hazardous to your macbook, so be careful and follow his tips for soldering. If you want, you can do the same to the opposite side for your left click, or just leave it the way it is. You can see a video of it in action after the break.

We use the Bus Pirate to interface a new chip without writing code or designing a PCB. Based on your feedback, and our experience using
the original Bus Pirate
to demonstrate various
parts
, we updated the design with new features and cheaper components.
There’s also a firmware update for both Bus Pirate hardware versions, with bug fixes, and a PC AT keyboard decoder. Check out the new
Hack a Day Bus Pirate page
, and browse the Bus Pirate source code in our
Google code SVN repository
.
We cover the design updates and interface a digital to analog converter below.
Concept overview
The Bus Pirate started as a collection of code fragments we used to test new chips without endless compile-program-run development cycles. We released it in a how-to and used it to demonstrate a bunch of serial interface ICs in our
parts posts
. This article introduces an updated design with new features and a bunch of improvements.
Surface mount design
Pull-up resistors on all bus lines with external voltage source
Software resettable 3.3volt and 5volt power supplies
Voltage monitoring of all power supplies
An external voltage measurement probe
Cheaper parts
Hardware
Click for a full size schematic image
(PNG). The circuit and PCB are designed using the freeware version of
Cadsoft Eagle
. All the files for this project are included in the project archive linked at the end of the article.
Microcontroller
We used a Microchip
PIC24FJ64GA002
28pin SOIC microcontroller (IC1) in this project. The power pins have 0.1uF bypass capacitors to ground (C1,2). The 2.5volt internal regulator requires a 10uF tantalum capacitor (C20). The chip is programmed through a five pin header (ICSP). A 2K pull-up resistor (R1) is required for the MCLR function on pin 1. Read more about this chip in our
PIC24F introduction
.
RS-232 transceiver
An inexpensive
MAX3232CSE
RS232 transceiver (IC2) interfaces the PIC to a PC serial port. This chip replaces the expensive through-hole
MAX3223EEPP+
used in the previous version of the Bus Pirate. The serial interface will work with a USB->serial adapter.
Bus pull-up resistors
The original Bus Pirate has 3.3volt pull-up resistors on 2 pins, but most of our tests required additional external resistors. The updated design has pull-up resistors (R20-23) on the three main bus signals (data in, data out, clock) and the chip select (CS) pin.
A row of jumpers (SV5) connects each resistor to an external voltage supplied through the Vext terminal (X4). Through-hole resistors are used like jumper-wires to make the PCB easier to etch at home.
We couldn’t find an elegant way to control an arbitrary voltage pull-up resistor array from a 3.3volt microcontroller. If you have any ideas, please share them in the comments.
Power supply
VR1 is a 3.3volt supply for the microcontroller and RS232 transceiver. VR2 is a 5volt supply. Both require two 0.1uF bypass capacitors (C3-C6). J1 is a power supply jack for a common
2.1mm DC barrel plug
. 7-10volts DC is probably the ideal power supply range.
The original Bus Pirate had dual power supplies, 3.3volts and 5volts, so most ICs could be interfaced without an additional power supply. A major annoyance was the lack of a power reset for connected chips. If a misconfigured IC needed to be power-cycled, we had to disconnect a wire. We got so tired of this routine that we added a software controlled reset to the updated design.
VR3 (3.3volts) and VR4 (5volts) are TI
TPS796XX
voltage regulators with an enable switch. A high level on pin 1 enables the regulator. A pull-down resistor (R13,R12) ensures that the regulators are off when the PIC isn’t actively driving the line, such as during power-up initialization. The datasheet specifies a hefty capacitor on the input (C23, C21) and output (C24, C22) pins, we used the same 10uF tantalum we use everywhere. An additional, optional, 0.1uF capacitor (C12,C11) can improve regulation.
The switchable regulators are powered by VR2, a 5volt supply. We did this because the maximum input for VR3 and VR4 is 6volts, leaving the device with a narrow 5.2-6volt power supply range. VR2 will work well above 10volts, and provides an adequate supply for the other regulators.
VR3 (3.3volts) has plenty of headroom to operate from a 5volt supply. VR4 (5volts) will lose about 0.2volts, but 4.8volts remains well within the acceptable range for most 5volt chips. In practice, and under light loads, we see less than 0.1volts drop-out from VR4.
Voltage monitoring
Voltage monitoring is a new feature we’re really excited about. Has your project ever mysteriously stopped responding because of an accidental short circuit? The Bus Pirate’s power supplies are equipped with voltage monitoring that can detect a change in power levels.
Each monitored signal is connected to an
analog to digital converter
(ADC) through a resistor voltage divider. Two 10K resistors (R10,R11 above) divide the input voltage in half, making it possible to measure up to 6.6volts with the 3.3volt PIC microcontroller.
The Bus Pirate has four voltage monitors. The 3.3volt and 5volt power supplies are monitored, as is the external voltage fed to the pull-up resistors. A fourth monitor is connected to pin 9 of the output header to make a voltage probe.
PCB
Click for a full size placement diagram
(PNG). The board is a quasi single-sided design, we etched ours in the lab on a single-sided photo-resist PCB. At the top, near C13, two jumper wires meet at a single via; we soldered one jumper wire to the other on the back of the board.

Using it
The diagram above shows the Bus Pirate pinout.
We made a cable with alligator clips on the end, and added labels to each wire so we don’t have to refer to this table every time we interface a new chip.

LTC2640 SPI digital to analog voltage converter
The Linear Technology
LTC2640-LZ8
is an 8bit
digital to analog converter
(DAC) programmed over
SPI
. A DAC is essentially a programmable voltage divider. They’re useful for recreating waveforms, such as audio signals. An 8bit DAC has 255 even intervals between 0 and the reference voltage, the L part we used has an internal 2.5volt reference.
The LTC2640 only comes in a small SOT223-8 package, so we made a breadboard adapter in the profile of a DIP-8 chip. Our LTC2640 footprint is included in the project archive attached at the end of this article.
The schematic above shows our test circuit for the LTC2640. It requires a 2.7-5volt power supply, we used the Bus Pirate’s 3.3volt supply. C1 is a bypass capacitor between the power pin and ground. Pin 8 is an active-low reset pin, tie it high for normal operation. Pin 7 is the DAC output, connect the Bus Pirate voltage measurement probe (ADC) here.

We connected the Bus Pirate to the LTC2640 as shown in the table. The LTC2640 doesn’t have a data output pin, this SPI connection remains unused.
The Bus Pirate’s hardware SPI library and software RAW3WIRE library are compatible with the LTC2640’s SPI interface. We used the SPI library; if you use the RAW3WIRE library be sure to choose
normal pin output
.

Press M for the Bus Pirate mode menu, choose 5 for SPI mode. There are a bunch of configuration options for the SPI module, use the default options for all of them. After SPI mode is ready we need to configure the power supply.

p opens the Bus Pirate power supply menu. We use the 3.3volt supply but not the 5volt supply. The voltage monitor verifies that the power supplies are off.

SPI>
Capital ‘W’ enables any power supplies selected in the previous menu, a small ‘w’ disables them. V displays the supply voltage monitor, which now shows 3.3volts output from the 3.3volt supply.
Now that configuration is finished, we can send commands to the LTC2640 over the SPI bus. The LTC2640 has a 24bit (3byte) interface protocol. The first byte is a command, followed by two data bytes. The LTC2640 is available in 8,10, and 12bit versions; the 8bit version uses the first byte to set the DAC value, and ignores the second byte.
SPI>[0b00110000 255 0]

<–DAC value
120 SPI WRITE: 0x00
<–don’t care
140 CS DISABLED
SPI>
Every SPI command begins by enabling the chip select pin ([). The first byte is the command to update the DAC (0b00110000), followed by the value to output (255), and a third byte that’s ignored (0). The command ends by disabling chip select (]).
We used an 8bit DAC with 255 even voltage steps, output set to 255 is 100%. We can use the Bus Pirate voltage probe to measure the output.

The LTC2640 has a low power mode, triggered by the command 0b01000000 and two bytes that are ignored. After the power down command we can verify that there’s output from the DAC. Write any DAC value to exit low power mode.
Taking it further
What’s the next step for the Bus Pirate? We’ll eventually make a final update to the design that includes USB on a professionally made, double-sided PCB. Power supply indicator LEDs were slated for this version, but didn’t get included. It would also be handy to have an AT keyboard connector for debugging without a PC.

On the bright side, both versions use the same source code base so you still get the new protocols and bug fixes.@error404 – Our first design has two 3.3volt pull-ups on the SDA and SCL signal lines. We often had to add external pull-up resistors to pull lines all the way to 5volts, or to use other signal lines (e.g. SPI).The new design has an array of resistors connected to an external voltage source through jumpers. Now we can use the on-board resistors to pull-up/down every signal line to any voltage that won’t fry the PIC.Could you elaborate a bit more on using a single-transistor switch in this design?@aa – We added LIN to the wishlist, CAN was already included. Can you suggest some fun chips we can use to prototype these libraries?",

ODBII isseveral protocols and different physical layersthat need a transceiver.CAN became a mandated auto diagnostic protocol in the US in 2008, and it was already widespread in Europe. Its also has a lot of other uses. CAN is used ona bunch of different physical layers. TheMCP2515is a CAN 2.0B controller with an SPI interface. It would work with the Bus Pirate’s SPI or RAW3WIRE library. You may even need one additional transceiver between the MSP2515 and the final CAN bus, depending on what you want to interface.These are just our general impression after investigating each protocol.

The
Neuros set top box
, called Link, is a disc-less computer running
Ubuntu
. Neuros encourages hacking and finding new ways to use the unit, as can be seen in their latest article explaining
how to get a Wiimote to work with it
. The results are pretty slick, as you can see in the video above. We can’t imagine trying to use the on screen keyboard with it, but it seems to work nice for basic navigation.

[Steve] was discussing airsoft with a friend when he came up with this idea. His friend was lamenting the lack of “action” style targets for their airsoft hobby. [Steve] took this as an opportunity to make his own
automated target system
. The targets themselves are made from
Construx
, a paper target and a piece of cloth to stop the airsoft pellets. Controlled by an
Arduino
and an
ioBridge module
, it has a web interface so he can switch programs from up range. You can see a video example of him shooting some targets after the break. Next,he should make it twitter where each target was hit.

Hackit: DTV Converter Boxes?

An anonymous
Slashdot
reader asked today what was the
best digital television to analog converter box
. He was looking for one with the best hacking potential. We actually purchased a Zenith DTT900 HD converter box this summer specifically wondering about the hacking potential. We did a teardown and you can find a
full gallery on Flickr
. Our conclusion was this: there’s not much there. You’re talking about a box that takes a digital RF signal and turns it into a crappier looking analog signal over composite. There isn’t much you can do outside of its designed use. Do you have any ideas what else can be done with it?
Slashdot commenter [timeOday] did
mention a Tivax brand box
that
features a serial port
. You can use it to issue remote commands to the box.
Not much has been said about the actual coupons. We’ve got a scan of them embedded below. The $40 coupons are essentially credit cards. We ran ours through a magstripe reader confirming this. Even though the card isn’t stamped with the recipient’s name, it is stored on the magstripe.

We thought the
Meggy had some serious potential
. The open serial port is ripe for the plucking, but has thus far been fairly unused. Here’s directions on how to
make your own serial cable
capable of connecting two Meggies. Basically, it is just modifying an audio cable, used to connect CDROMs to the
motherboard
. The cool thing about this is that the resulting crossover cable should work on any
Arduino
that is programmed via an FTDI cable.

External Antenna On Panasonic CF-R1

[Steven] managed to get his hands on a Panasonic CF-R1 for pretty cheap. Though it is a decently powerful machine, it was built in 2002 and didn’t come with an internal wireless card. It did, however have a mini-PCI slot. [Steven] promptly installed a wireless card, but found the internal antenna lacking. The solution was to
custom mount an external antenna
. Mounting it was fairly easy, he removed the phone jack and epoxied the connector in its place. The reception was greatly improved. He says he went from seeing 6 access points to 31 as soon as he installed it.
Similar things have been done to the Eee PC 900
.

Many good internal laptop antennas have gain on the order of 3 or 4 dB, while the little whip antenna in the photo is only good for about 1dB gain. I’ll admit, I did do this myself one time, but it was on a laptop that already had built in wireless(and antennas) so the purpose was to be able to connect an external 24dB grid antenna. I was also able to add my external SMA connector without sacrificing one of the existing jacks, and I don’t see why he couldn’t have done the same…",

At this year’s Consumer Electronics Show,
Chumby
unveiled their latest prototype. It’s a network connected digital picture frame that runs Flash widgets. Just like the current Chumby model, they’re publishing the software and hardware under a license designed to let you hack it. They let us borrow one of their open chassis evaluation kits to teardown and photograph. We’ve got more pictures, full specs, and the schematics below.
The new version has an 800×600 LCD touchpanel. They’re still using an open source
Linux
backend, but they’ve updated the UI. Chumby widgets are now managed on the device. Before, users had to log into the website and then have their chosen widgets pushed down to the Chumby. The software is designed so that it could be a user’s primary photo management application. It instantly recognizes inserted memory cards and lets users drag and drop photos into the widget playlist. The device integrates seamlessly with PhotoBucket letting you easily upload new galleries. You can send these to other Chumby users (Chums) as well.
Keep in mind that this is just an evaluation kit, so it’s mounted in a generic wooden photo frame.

On the left side are stereo speakers connected to the onboard amplifier. The large orange ribbon at the bottom contains all of the display electronics. The lower connector on the right edge powers the backlight. The upper four wire ribbon is for the touchscreen. The cutout at the top is for the USB
WiFi
card. The coincell holder is battery backup for the real time clock. There are two control panel buttons along the top.
The board includes several headers to make debugging easier. The pins in the lower left provide a serial console (
detail
). The larger grouping is the CPU JTAG. Next to that is an MMC port for the initial boot image. The cryptoprocessor also has a JTAG connector.
Flipping the board over you can see the optional video camera daughter card.
The silkscreen next to the RAM on the front side says this board version is Stormwind v8.0 revC.

The front side of the board is where most of the interesting bits are. The reset and user buttons are located in the upper left. Next to that is an SD card socket and a CF card socket. The power jack and microphone are on the upper right corner along with the amplifier circuitry. Below the CF is a TSOP socket holding a Hynix HY27UF081G2A-TP memory device. Under that is the main processor, a
Samsung S3C6410
. It’s a 533Mhz ARM11 CPU. To the right of the chip, are two Hynix RAM chips. This new Chumby can be built with 2-8GB of storage. Below that is the Novatek NT39703 display driver. The crypto processor is left of there. The headphone jack is located in the lower right corner of the board. The board’s lower edge features three USB ports. A USB WiFi card is plugged into one of them. We assume not integrating WiFi means they don’t have to deal with FCC approval; they just use an approved card. The
USB
and memory cards are controlled by the Alcor Micro AU6350 located next to the camera module.
For those looking for even more detail, here are the full schematics:

Passive MIDI Foot Switch

[Matt] was looking into some software that allows him to use his audio card as a means to control analog audio devices. After seeing how it worked, he got an idea to try to do the opposite. He is sending a signal into his audio input, and piping it to a pice of MIDI software. The input he has chose is a
foot switch
. To create the signal, he simply needed to supply voltage while the switch was depressed. You can see above that he used a battery and a simple contact switch to send the signal. He then piped it to a virtual MIDI port using
Maple Virtual MIDI Cable
. Unfortunately, this isn’t suitable for knobs, but that may be next on his list.

When the band support on [David]’s Casio CFX-400 Scientific Calculator Watch finally broke after 10 years of use, he found it almost impossible to find another watch with the same functionality. Like any good engineer, [David] decided to design a watch to meet his needs. The result of his endeavors was the
µWatch
, a programmable watch based on a PIC24 with both RPN and Algebraic calculation modes. The watch runs open source software and is expandable thanks to a serial port, an ICSP programming port, and a spot for an infrared LED on the board. On his site, [David] shows how he made the first µWatch and offers kits for anyone who wants to build their own. We’ve been told that the next batch of kits will be made available in 1-2 weeks and are expected to sell out fast.

If you are interested in trying out some home automation, but don’t want to get into the
potentially dangerous
area of hacking your house wiring, consider these
servo switches
. These allow you to flip a switch, using a servo. They are clean, temporary, and fairly compact. You can
purchase them at oomlout.com
or download the designs and build your own.

High Frequency Start Box

"Tool Hacks"

"tig",
"welding"

When welding with an AC arc welder, it is often necessary to “scratch start” them to get the arc going. For those unfamiliar, it is just like it sounds. You drag the head across something just like a giant match. There are some that come with an arc stabilizer or “high frequency starter”. This is preferred, but they can be hard to find. [Bill] shows us how to
make one of our own
. Though you may have an easy enough time finding a big transformer, you might run into some difficulty finding the capacitors, and tungsten spark gaps. If you manage to get your hands on them, you can follow [Bill]’s schematic and build one of these starters for yourself.

For a V8 that would be 8 firings per revolution so 50*8=400. An automotive coil has a service life of years and is cheap to get as well as easy to deal with.Just wanted to point that out for anyone coming across this information.",

"content": "Today we setup and ran our build of the High Frequency Start Box, and it worked perfectly! Our shop foreman was thrilled to add it to his set of tools. The setting on the lamp switch dimmer setting seems to have limited impact on the results of the arc started, though we may learn otherwise with time and experience. He was able to lay down a nice bead in some aluminum test material with his Hobart stick welder attached to a tig torch and the HF box. The way the arc jumped and started immediately was incredible. It jumped between the test material and the tungsten at about 5/16″ of separation.When working with steel, the HF start box helps get started easily, but can be turned off once the arc is started. In aluminum, leaving it on made the arc much more stable, and gave a broader warning zone showing that you are moving out of the target separation between electrode and work piece, without breaking the arc immediately. Seems like it would help learners develop a feel for proper positioning more quickly. No idea on what impact it would have on the life of the spark gaps or any other component of the system.We used 118X80X20mm Ferrite Core… it was larger than necessary. If we build another we’ll try a 102x65x20mm or a 85x55x20mm Ferrite core.An important note for anyone replicating this, be sure that the ground is properly connected to your mains ground… otherwise you end up with strange electrical feed backs. It caused an auto feed table on a mill in the shop to start feeding until we tracked down a faulty ground in the electrical outlet we had the HF box plugged into for testing. There was definitely some sort of undesirable feedback going on without the ground properly connected.",

[jwad650] wanted a
remote controlled power strip
. These are fairly expensive, with a
single outlet
running roughly $15. He was able to build a 6 outlet version for about $50. He is using an
SIS-7c
to decode signals from a universal remote. Each plug is individually controlled by a 3Amp relay. Be careful making this, there’s lots of nasty shock potential in that mess of wires. We recommend that you confine it in an enclosure as well. [jwad650] plans on adding an enclosure, as well as LED indicators and fuses. You can see a video of it in action after the break. If you want more information about working with relays, check out the
working with relays
writeup.

Besmoke
is a fluid dynamics engine. It is compatible with any multitouch system, as well as the accelerometer in an
iPhone
. It also accepts audio input. The audio input can turn it into a fancy music visualizer that would even work with live or acoustic music. Different frequencies cause fluid to be injected from different “emitters”. There’s great info on his page, including the papers that he based this off of. We’ve covered [Eric]’s work before with his
election party light system
.

[Aki]’s Nikon D2H did not come with an autofocus assist light. His other cameras have them, and he likes the feature, so he decided to
hack one into his D2H
. He wired into the AF system, so that his LED gets voltage when the shutter release is pressed half way. The circuit needs refinement though, he found that the light was staying on during shutter release and affecting his light metering. You can see the hack in action after the break.

Last week we introduced
a new version
of the
Bus Pirate universal serial interface tool
. The last firmware update included an AT keyboard decoder library for both hardware versions.
There’s a ton of old AT keyboards making their way to the landfill. We’ll show you how to recycle one as an input device for your next project.
Connection
Bus Pirate
PC AT keyboard (pin #)
SDA
KBD Data (3)
SCL
KBD Clock (1)
+5volts
VDD (5)
GND
GND (2)
AT keyboards communicate over a bidirectional two-wire interface. The bus is
open collector
, but keyboards already have internal
pull-up resistors
. The PC AT keyboard protocol is described
here
. We used our Bus Pirate tool to demonstrate the keyboard protocol, but the same basic principals apply to any microcontroller.
We connected the Bus Pirate to the keyboard as outlined in the table. We believe that
this
is a through-hole female AT keyboard jack, but we haven’t tested it. Do you know of a source for new sockets?
Protocol
The keyboard provides the clock signal for
all
data transfers; the PC side resembles a slave device. None of the existing Bus Pirate interface libraries work with an external clock, so we wrote a simple AT keyboard decoder library. The library depends on the keyboard’s clock signal, and it’ll hang if the keyboard fails or isn’t connected. If you use our library in your own project, consider adding a timeout delay in the readbit() and writebit() functions.
PC to keyboard command codes
Code
Command
0xed
Set status LEDs
0xee
Echo 0xee
0xf0
Set scancode type
0xf3
Set repeat rate
0xf4
Keyboard enable
0xf5
Keyboard disable
0xfe
Resend last byte
0xff
Reset keyboard
A PC uses these commands to control various functions of an AT keyboard. The keyboard responds to commands with an acknowledge byte (oxfa). In our experience, the keyboard will reset if the response byte is not read shortly after the command is sent.
Keyboard to PC response codes
Code
Response
0xfa
Acknowledge
0xaa
Self test passed
0xee
Echo response
0xfe
Resend last byte
0x00 or 0xff
Error or buffer overflow
The keyboard has a number of single byte response codes. Most PC commands are acknowledged with 0xfa. 0xaa is sent after a keyboard reset.
Setup the Bus Pirate
HiZ>m
1. HiZ
…
9. PC AT KEYBOARD
MODE>9
<–set mode
900 MODE SET
X02 PC AT KB DECODER READY
PC AT KEYBOARD>
First, we setup the the Bus Pirate for AT keyboard mode, option 9.
PC AT KEYBOARD>p
<–power supply setup
W/w toggles 3.3volt supply?
1. NO
2. YES
MODE>1
<–no 3.3volt supply
W/w toggles 5volt supply?
1. NO
2. YES
MODE>2
<–use the 5volt supply
9xx SUPPLY CONFIGURED, USE W/w TO TOGGLE
9xx VOLTAGE MONITOR: 5V: 0.0 | 3.3V: 0.0 | VPULLUP: 0.0 |
PC AT KEYBOARD>W
<–capital ‘W’, turn supply on
9xx 5VOLT SUPPLY ON
PC AT KEYBOARD>
Next, we configure the Bus Pirate’s power supply to provide 5volts for the AT keyboard.
PC AT KEYBOARD>r
<–read byte from keyboard
x30 PCATKB READ: NONE
<–no data available
PC AT KEYBOARD>
The AT keyboard library follows the standard Bus Pirate syntax. Numeric values are sent to the keyboard as bytes, ‘r’ reads a byte from the keyboard. The protocol is clocked by the keyboard so bitwise operations are disabled. If no data is available, the read will return ‘NONE’.
Setup the keyboard
PC AT KEYBOARD>0xee r
<–send 0xee, read one byte
X20 PCATKB WRITE: 0xEE GOT ACK
<–write oxee, got ack bit
x30 PCATKB READ: 0xEE
<–read 0xee, echo was successful
PC AT KEYBOARD>
We can test the connection to the AT keyboard using the echo command, 0xee. The keyboard will respond 0xee if our connections are correct.
The keyboard responds to commands with an ACK bit at the protocol level, and then again with an ACK byte. We found that our test keyboards reset automatically if the ACK byte wasn’t read immediately after sending the command.
PC AT KEYBOARD>0xee
<–echo command
X20 PCATKB WRITE: 0xEE GOT ACK
<–wrote echo, got ACK
PC AT KEYBOARD>r
<–read one byte
x30 PCATKB READ: 0xAA
<–read 0xaa, reset indicator
PC AT KEYBOARD>
Here, we tried to send the echo command and then read the reply later. The keyboard reset automatically and replies 0xaa, self-test passed.
PC AT KEYBOARD>0xff r r
<–reset command, read two bytes
X20 PCATKB WRITE: 0xFF GOT ACK
<–write reset command, got ACK
x30 PCATKB READ: 0xFA
<–command ACK byte
x30 PCATKB READ: NONE
<–read once more to reset
PC AT KEYBOARD>
The keyboard is reset by writing the command 0xff, and reading two bytes. The Keyboard won’t reset until the second byte is read.
PC AT KEYBOARD>r
<–read a byte
x30 PCATKB READ: 0xAA
<–reset success
PC AT KEYBOARD>
A short period after reset we can read the power on self test (POST) results, 0xaa indicates POST success.
PC AT KEYBOARD>0xf5 r
<–disable the keyboard
X20 PCATKB WRITE: 0xF5 GOT ACK
<–wrote command
x30 PCATKB READ: 0xFA
<–read ACK byte
PC AT KEYBOARD>0xf4 r
<–enable keyboard
X20 PCATKB WRITE: 0xF4 GOT ACK
<–wrote command
x30 PCATKB READ: 0xFA
<–read ACK byte
PC AT KEYBOARD>
0xf5 disables keyboard input. 0xf4 enables the keyboard and clears the buffer.
PC AT KEYBOARD>0xed r 0b111 r
<–set indicator LEDs
X20 PCATKB WRITE: 0xED GOT ACK
<–set LED command
x30 PCATKB READ: 0xFA
<–command acknowledged
X20 PCATKB WRITE: 0x07 GOT ACK
<–send LED value
x30 PCATKB READ: 0xFA
<–value acknowledged
PC AT KEYBOARD>
The num, caps, and scroll lock LEDs are controlled by the 0xed command. The last three bits of a second byte (ob111) indicate which LEDs to light. It’s very important to perform all four byte operations within the keyboard timeout period, or the keyboard will reset.
PC AT KEYBOARD>0xee r
<–echo test command
X20 PCATKB WRITE: 0xEE GOT ACK
x30 PCATKB READ: 0xEE
PC AT KEYBOARD>0xfe r
<–repeat last byte command
X20 PCATKB WRITE: 0xFE GOT ACK
<–write repeat command
x30 PCATKB READ: 0xEE
<–previous byte is repeated
PC AT KEYBOARD>
The last interesting keyboard command is the repeat byte command. 0xfe causes the keyboard to send the last byte again. This is a useful command if there was a error in the previous transmission.
Read key presses
Key presses are buffered by the keyboard until we read them.
PC AT KEYBOARD>r
<–read byte
x30 PCATKB READ: 0x29
<–space scancode
PC AT KEYBOARD>r
<–read byte
x30 PCATKB READ: 0xF0
<–key release scancode
PC AT KEYBOARD>r
<–read byte
x30 PCATKB READ: 0x29
<–space scancode
PC AT KEYBOARD>
A key press sends
scancodes
, multi-byte sequences that represent the key presses. In the example, we pressed space which has the scancode 0x29. When a key is released, the keyboard sends 0xf0 and the scancode for the key (0x29). Each key press results in a similar three part sequence.
PC AT KEYBOARD>r:4
<–read 4 bytes
x31 PCATKB BULK READ, 0x04 BYTES:
0x29 0xF0 0x29 NONE
<–space scancode
PC AT KEYBOARD>
This is just a simplified version of the previous example. Rather than read three bytes individually, we used the bulk read command. Again, we get the space scancode sequence. Our attempt to read a non-existant fourth byte fails.

It’s quite possibly older than I am.http://img443.imageshack.us/img443/5462/img1285ab7.jpgAn old midi-computer cable I had.note: these pictures were taken after I had hacked it together. This cable used to have two MIDI female ends, as all MIDI cables do, one for in, one for out.top:http://img217.imageshack.us/img217/3552/img1288tm6.jpgfront:http://img84.imageshack.us/img84/2533/img1287nq6.jpgfirst, I chopped off one of the midi ends pretty high up, but discovered that there were only three wires inside! after checking, I found out that MIDI only uses three of the pins.What I did then was chop off the cable at the base of the connector. Once that was done, the rubber jacket on the connector actually slid off quite easily, with a bit of force.Inside that, there was the metal connector, and a blob of some sort of plastic on the end. The plastic was a bit more difficult to remove, but once I got it off, I had a simple 5-pin din socket, with connector stubs on the other end.I wrapped and taped some wire on the end.results:top:http://img294.imageshack.us/img294/7818/img1289ez3.jpgfront:http://img509.imageshack.us/img509/1515/img1290re7.jpgand then that could be wired straight into an arduino, being at an electrically compatible level (I think).Does anyone have any advice on how to use an AT keyboard as a regular input device on a USB only computer?It looked like the PS/2 and AT protocols were pretty much the same, so could I wire in my keyboard to a ps/2 to usb adapter?

When we first saw [Jeffrey Nelson]’s
G1 based robot
we immediately wondered what the transport for the controls was. The
G1
‘s hardware supports
USB
On-The-Go, but it’s not implemented in Android yet. It turns out he’s actually sending commands by using
DTMF
tones through the
headphone adapter
. The audio jack is connected to a DTMF decoder that sends signals to the bot’s
Arduino
. He wrote client/server code in
Java
to issue commands to the robot. You can find that code plus a simple schematic on his site. A video of the bot is embedded below.

TEMPEST is the covername used by the NSA and other agencies to talk about emissions from computing machinery that can divulge what the equipment is processing. We’ve covered a few projects in the past that specifically intercept EM radiation.
TEMPEST for Eliza
can transmit via AM using a CRT monitor, and just last Fall a group showed how to
monitor USB keyboards remotely
. Through the Freedom of Information Act, an interesting article from 1972 has been released.
TEMPEST: A Signal Problem
(PDF link dead, try
Internet Archive version
) covers the early history of how this phenomenon was discovered. Uncovered by Bell Labs in WWII, it affected a piece of encryption gear they were supplying to the military. The plaintext could be read over that air and also by monitoring spikes on the powerlines. Their new, heavily shielded and line filtered version of the device was rejected by the military who simply told commanders to monitor a 100 feet around their post to prevent eavesdropping. It’s an interesting read and also covers acoustic monitoring. This is just the US history of TEMPEST though, but from the anecdotes it sounds like their enemies were not just keeping pace but were also better informed.

At first glance, this may look like a retro styled
monome
, but it is actually quite different. Merging a
Project64
key pad and a
Voice Shield
for Arduino, [Spikenzie] has
made a sound effects box
. Each button triggers a unique sound that is stored in the Voice Shield. Of coarse, it will be like a game of
memory
trying to remember what sound is where. You can see a
demo video here
.

You probably saw [Phillip Torrone] and [Limor Fried]’s
twittering Kill A Watt
earlier this week. It was an entry in the
Core77/Greener Gadgets Design Competition
. We saw a little bit about how it was assembled, but now they’ve posted a
full guide to assembling the hardware
. Each Kill A Watt gets an XBee radio that transmits back to a receiver that logs the power usage. The difficult part when putting this design together was the XBee required 50mA when transmitting. This is well above the Kill A Watt’s internal power supply. They remedied this by adding a 10,000uF supercap to act as a rechargeable battery. The daily twittering is just a side-effect of the project. The Kill A Watts transmit every 2 seconds, so you’ll get a very accurate report of your power usage. This is a great project for renters who can’t permanently modify their power infrastructure. Each Kill A Watt can support quite a few appliances since they’re rated for 15A, ~1800W.

Reader [Ramon Viladomat] sent in what he has been working on over the last year at the Universitat Pompeu Fabra in Barcelona. Tired of see nothing but zooming map demos, he created a roleplaying game that takes advantage of the
reacTable
‘s multitouch interface. Along with
multitouch
, the reacTable also uses tangible
fiducial markers
to represent objects and as an alternative input method. Embedded above is a video demoing the interface and gameplay (starts at 3:43). The game lets you move your miniature through a virtual world. The surface shows you how far you can move dynamically as your action points regenerate and slowly reveals more dungeon as you discover it. You can pause the action and use gestures to set attack patterns. We really like this demo and would love to see someone build one using a popular tabletop game like
Warhammer 40K
. Embedded below is a demo of the associated map editor.

Frozen Cache
is a blog dedicated to a novel way to prevent
cold boot attacks
. Last year the cold boot team
demonstrated
that they could extract encryption keys from a machine’s RAM by placing it in another system (or the same machine by doing a quick reboot). Frozen Cache aims to prevent this by storing the encryption key in the CPU’s cache. It copies the key out of RAM into the CPU’s registers and then zeroes it in RAM. It then freezes the cache and attempts to write the key back to RAM. The key is pushed into the cache, but isn’t written back to RAM.
The first major issue with this is the performance hit. You end up kneecapping the processor when you freeze the cache and the author suggests that you’d only do this when the screen is locked. We asked cold boot team member [
Jacob Appelbaum
] what he thought of the approach. He pointed out that the current cold boot attack reconstructs the key from the full keyschedule, which according to the Frozen Cache blog, still remains in RAM. They aren’t grabbing the specific key bits, but recreating it from all this redundant information in memory. At best, Frozen Cache is attempting to build a ‘ghetto crypto co-processor’.
We stand by our initial response to the cold boot attacks: It’s going to take a fundamental redesign of RAM before this is solved.

I thought of crypto chips, but then, who’s to say you can’t probe one of those for the data it contains?It seems to keep coming back to physical access owning the system regardless of measures. Doesn’t the real question then become how many people you really need to stop, not how many can you stop?I guess the real question I’m asking is why should I be worried about this?

There is obviously no such thing as a completely physically secure design, but there are plenty of things that come close–some things that come to mind are certain types of very high security microcontrollers (probably used in ATM machines)–these guys often have SRAM on chip and on-chip sensors which will immediately wipe clean the encryption keys in an instant (on a digital signals timescale, of course).

The physical security can be circuvented via an internal threat(disgrutled employees, personal gain from corporate information, etc.), or even social engineering. For example, if the keys stored in the server’s RAM were stolen from a web server (using SSL to encrypt traffic), a rogue server could be set up with the use of the keys. Therefore it could effectively sit in between the connection legitimately, without either party knowing its there. Extremely dangerous and difficult to detect. That is why securing the keys is a key (pardon the pun) concern, and usually achieved through tamper-proof, dedicated hardware (nCipher springs to mind). The keys never leave their hardware and can only be accessed by administrators, with a KofN approach (multiple user authentication). This mitigates the risk considerably, and helps regulatory compliance in a lot of cases. It’s quite an interesting threat and one that not many are protecting against. The difficulty to access the keys is high, but so is the damage that could be caused by not storing them away from the RAM in case it were to happen.",

[Alex] was frustrated by the amount of time it took to start prototyping with an AVR ATtiny. To make things easier, he built
headers that carry the 8 and 20 pin chips
and plug directly into breadboards. The boards include a 6pin ISP header, resonator, pull-up resistor, reset, and blocking caps. The ATtiny2313 version also has a serial connection header. This is a
prototype
though, and he forgot to route one of the connections. He plans on having a large batch of boards ready for next month.

Here’s another bizarre keyboard mod to add to the pile. Unlike previous
typewriter style
mods, this one
uses Scrabble tiles
. All of the tiles were hand beveled and attached to a clicky keyboard. The Num, Cap, and Scroll lock buttons have their letters’ hollowed out so the LED light will shine through.

Bittorrent
is a great distribution method for large files, but its heavy bandwidth usage can be disruptive to both work and home networks. [Brett O’Connor] has decided to
push all of his torrenting activity into the cloud
. Amazon’s
EC2
service lets you run any number of Amazon Machine Images (AMI, virtual machines) on top of their hardware. You pay for processing time and data transferred. [Brett] put together a guide for building your own
seedbox
on the service. First, you set up the Security Group, the firewall for the machine. Next, you specify what AMI you want to use. In this example, it’s a community build of
Ubuntu
. Once you have your SSH keypair, you can start the instance and install Apache, PHP, and
MySQL
.
TorrentFlux
is the web frontend for bittorrent in this case. It manages all the torrents and you just need to click download when you want to grab the completed file.
Even if you don’t plan on setting up a seedbox, the post is a straightforward example of how-to get started with EC2. He’s not sure what the cost will be; the current estimate is ~$30/mo.

PandaLabs has identified a botnet running a
malware campaign impersonating president-elect Obama’s website
. The front page of the site features a sensational story titled “Barack Obama has refused to be a president”. Clicking the link will download the malware and make the target’s machine part of the botnet. They’re using
fast-flux
to assign the malicious domains to the massive number of compromised nodes that are hosting the actual site. The team has contacted the domain name registrar in China to get the domains removed. Using a sensational headline is not new to malware; it’s how the
Storm Worm
got its name.

Now that the iphone-dev team has
unlocked the iPhone 3G
they’re moving onto jailbreaking the
iPod Touch 2G
. While they have a fully working jailbreak, it’s not yet in a user friendly format. [MuscleNerd] did a
live video demo this afternoon
to show what progress they had made. It starts with him showing the
iPod
on but not booting. He’s already patched the kernel, but it’s failing the signature check in iboot. He then uses the team’s recoverytool to exploit a hole in iboot and patch out the signature check. The ipod then boots normally and he shows non-App Store software like Mobile Terminal,
Cydia
, and an NES Emulator (which makes use of the iPod’s internal speaker).
The
redsn0w jailbreak
works, but it has to be applied via tether every time the iPod boots. The team won’t release anything until they’ve found a way around this problem. For more insight into the boot process, check out our coverage of their
Hacking the iPhone
talk at 25C3.

The
CREATE USB Interface (CUI)
was a project that came out of UC Santa Barbara around the same time the
Arduino
was being developed. It has a USB port, a PIC18F4550, and a prototyping area. It was designed to enable easy interfacing with the real would through many A/D inputs and general I/O ports. It supports both OSC and MIDI-over-USB natively. The biggest difference between the CUI and the Arduino is its
USB support
. The Arduino uses an FTDI chip to create a serial interface to its onboard AVR. The CUI’s PIC has native support for USB. That means you can have the CUI appear to be any USB HID device you want:
keyboard
,
mouse
, game controller, etc.
The Arduino has a friendly development environment and a large following though. CUI create [Dan Overholt] decided to add an ATmega168 to his board to get the best of both worlds, the
CUIduino
(scroll down). It can be programmed just like any other Arduino compatible device, but the having the CUI parent means your Arduino project can behave like a native USB HID gadget.
[Thanks Peter]

What you see above is the culmination of [Zach Smith]’s work
building a pinch wheel style extruder
for the RepRap. The current RepRap 3D printer uses a
screw mechanism
to push 3mm polymer filament into a heating barrel where it is melted and then extruded through a fine nozzle. [Zach]’s new version uses a drive gear from SDP/SI mounted directly to the DC motor we saw him
teardown earlier
. He’s
redesigned the carrier
for the extruder as well. It’s now much lighter and has provisions for mounting current and future controller electronics along with a magnetic rotary encoder. In the last two days, he’s been doing
real world testing
. It’s been doing well, but he’s learning to do things like always using a full spool and not trying to run short lengths back to back.

Network engineer [Mario Giambanco] recently purchased a cable to move his flash off camera. Unfortunately, it ended up way too short for his purposes. Instead of purchasing a slightly longer proprietary cable, he decided to employ what he had around him: a lot of cat5e cable and ethernet jacks. He cut the cable close to the center in case things didn’t work out and he’d need to repair it. His post on building the custom
ethernet flash extension cable
goes into heavy detail to make sure you get it right the first time. He’s tested it using both five and 50 foot pieces of cable with no apparent lag.
This isn’t the first time we’ve seen cat5 repurposed:
composite video through cat5
,
vga cat5 extension
, and
cat5 speaker cables
.

One I got from a small East German camera, went up to 450 volts between the ground and trigger pin. The flashes fire when the trigger pin is connected to the ground, which in old cameras and flashes may not have actually been grounded to anything at all. So user beware.Most flashes do not use the connection to send the voltage from the cap to the xenon tube firing system. Most. Once you see a flash with 400+ volts across that gap, you have to wonder though.For older cameras and flashes, this would have been too many cables to have bothered with. You just need the connection. Now, though, the flashes use serial signals to talk to the camera,. And the camera companies like to charge a lot for even short cables. This looks like a nice project for anyone without real wireless flashes or ebay wizards. But only with newer flashes and known gear.",

Giles Bowkett
] has been working on a music library for Ruby called Archaeopteryx. He describes it as a “
Ruby MIDI DJing/live-coding thing
“. In the video above, He’s using it to generate and then morph rhythms. The Ruby code is directly controlling the step sequencer in
Reason
. It’s an interesting approach to music development. The video above gives a full intro to the probability approach to generation. To really get a feel for the library, we suggest you watch his presentation from RubyFringe. It shows him playing music by
editing a live block of code
. Check out his
Vimeo feed
for many more demo videos.

Zero Day has an interview with German researchers who have found a way to
take down the Storm Worm botnet
. Their program,
Stormfucker
, takes advantage of flaws in Storm’s command network: Nodes that are
NAT
‘d only use a four-byte
XOR
challenge. Nodes that aren’t NAT’d are only using a trivial 64bit RSA signature. Their solution can clean infected machines and also distribute to other nodes. Unfortunately, installing software without the user’s consent is the exact same behavior as malware. Don’t expect to see this in any sort of widespread use. The researchers did point out that some ISPs have moved to shutting off service for infected customers until their machines are cleaned.

[mightyohm] put together a nice piece of lab kit. It’s a
PID controlled hot plate
. The plate is capable of reaching 500F, hot enough to do
SMD reflow soldering
. The large chunk of metal has a hole drilled through the center to contain a cartridge heater. A thermocouple is used to monitor the temperature of the plate. Ceramic standoffs separate the plate from the rest of the device, but he still needs to come up with a way to stop the radiant heating. The control box houses the surplus PID controller along with the power switch and solid state relay (SSR).

To lower the radiant heating, one might polish that base plate (I guess), but maybe there are better materials to isolate the hot plate. I’d love to make a suggestion, but I don’t know any properties from any materials.I’m guessing that the time to heat up that block (even with a 500W heater and a PID controller) does take a minute and might be quicker by using a thinner block. So is there a specific reason why the hot plate is so massive?Seems like a very handy tool, I might make my own one day.",

With a stereo microscope this becomes a very powerful tool for doing very tiny components or chips with lots of leads. You could probably do BGAs with this setup if you tried hard enough.The biggest downside is that it only works with single sided PCBs unless you are creative with the use of spacers and stuff.I used to do soldering work professionally at a large electronics company and this is what our engineering lab used to solder components as small as 01005’s. That’s half the size of an 0201, smaller than a grain of salt.Thanks for the suggestions about the refractory materials – my biggest concern is that most of them are possible carcinogens. Aluminum foil may help. One issue I have discovered is that the ceramic standoffs actually conduct heat quite well, better than I had expected, so that may be the primary heat path instead of radiant.",

[glacialwanderer], who you may remember from his
CNC machine build
, recently completed an
electric spinning wheel
. Spinning wheels are used by knitters to turn raw sheep’s wool into yarn. He went through several iterations before arriving at a good design. Besides the motor, there are two major components to the spinning wheel: the flyer and the bobbin. A Scotch tension brake is used to slow the rotation of the bobbin in relation to the flyer. This causes the wool to twist as it’s pulled on.
He initially tried to just use a dimmer switch with an AC motor. That quickly burnt up. The next version used a sewing machine motor since they’re designed with a variable speed control. Unfortunately, it didn’t have enough torque at low speeds. The final design used a DC motor with a
SyRen motor controller
. It offered plenty of power and at ~$150 it’s still less than the cheapest commercial models on eBay. You can see a video of it and the spinning process embedded below.

"content": "“Electric” spinners as based on a mains power AC motor are not very good. If you want a good portable type spinning wheel you have to buy an “electronic” one. The difference is explained here.Roberta Electronic SpinnerThe Difference Between “Electric” and “Electronic” SpinningThe difference is not so much about the ability of the spinning machine to do a job, but more about the lasting ability of the motor.There is a difference to consider, in the spinning ability of motorised spinners. There are bobbin-led machines (Irish brake design) or flyer-led machines (Scotch tension design). The Roberta is bobbin-led because this allows better control of the drafting rate. If the flyer is driven by a motor (as with the scotch tension design), the speed needs to be altered continually to suit the drafting speed or spinning speed. Failure to handle this correctly, will affect the quality of the yarn produced. With the Roberta electronic spinner (bobbin led),this is not a concern, because the motor speed is affecting the bobbin, not the flyer. The motor affects only the twist rate, not the pull-in rate for drafting. No broken yarn, when starting up, with a motor speed too fast. The Roberta electronic spinner design is based on the same design as is found in modern spinning mills today. The only difference being, that in the mills they run at 6000 revolutions per minute. Just a little faster than the Roberta!“Electric” means power goes straight to the motor and is adjusted with a speed control. The control is a resistor, that restricts the voltage going to the motor to make it go faster or slower. Electric (sewing-machine-type motors) are not designed to do the job required of them in spinning, which is high torque (twisting effort of the shaft), at slow speeds. These straight electric motors are designed to run at high speeds under load. They use AC (alternating current) power. When you restrict the voltage to slow it down, and then put it under load, you stress the motor, and a burning of the armature (the middle core) will occur. This will be very bad, if the motor actually stalls under load. With all this stress and burning on the armature surface, the motors are not likely to last more than 5 years with constant use.“Electronic” means that the power or current is modified, and is monitored and controlled according to the demands placed upon the motor by the person using it. All the disadvantages of the “Electric” are removed. The power voltage is reduced and changed to DC (direct current). This type of current gives very strong torque to the motor at slow speed. No harm can come to the motor because of the reduced voltage. The DC motor is designed for this use. In addition, the current is automatically and continually adjusted between amperage and voltage according to load and speed factors wanted. There are a number of electronic components in the circuit to accomplish this. They include a transistor, transformer, bridge rectifier, potentiometer, diodes, and a capacitor.The Roberta has great advantage over other spinners with its bobbin-led, electronic system, and the 10-year guarantee on the motor is unmatched.Ian Spark, Ertoel Spinning wheels",

In a sewing machine, where they use these type of motors, they get the slower sewing speeds, by using gears. In a spinning wheel,if you lower the voltage through the foot pedal, to get the lower slow speeds, it will eventually burn out the AC type motor, because it is designed to run at higher speeds. They will last less than 5 years of constant use.You only need variable slow speeds on a spinning wheel, if it is flyer driven. You do not have to alter the motor speed (after the first setting), if it is bobbin driven. Also the yarn does not break either, when you start it up. The only kind of motor to use in a motorised spinner, is a DC motor which require electronics to support and protect it. DC motors give high torque at low speeds. Just what you need in a good motorised spinner.Ian Spark",

The reason why a bobbin driven spinner is best is that everything is more controllable, and you do not have to keep altering anything as you spin the yarn and fill a bobbin. A motorised spinner that has a driven flyer can be a bit problem, if you do not keep up the speed of drafting the fibre properly, as the yarn will break. Also you have to stop frequently to alter the brake on the free turning bobbin, as it grows fatter in the middle, and gathers more yarn on the bobbin. These things are not a problem with a bobbin driven spinner.Ian Spark",

[Luke Hutchison] has come up with a rather clever hack to get
multitouch support on the G1
. He wrote a patch against the Synaptics touchscreen driver. When two fingers are placed, the driver reports the x/y of the midpoint and a radius for the size field. If only one finger is used, the size is reported as zero. The nice thing about this approach is that it’s backwards compatible; the extra data will be ignored by current apps. Unfortunately, Google’s Android team says that if multitouch is ever added, it would identify individual fingers and definitely not using this method.

[I)ruid] from BreakingPoint Labs has been doing quite a bit of protocol reverse engineering as part of his work. He put together a
post covering some of the tools
that have been useful for this task. Text-based protocols have a lot of human readable characters that can help you identify fields. Binary protocols don’t have this luxury though. He recommends the
Protocol Informatics Project
for tackling these situations. It applies bioinformatics algorithms to network traffic. You give it a packet dump of the protocol and it compares them to find similarities the same way genetic sequences are compared. It can be confused by protocols that waste a lot of space, but it’s still a very clever approach to reversing.

[Wu Yulu] is a Chinese farmer with no formal mechanical training. He’s been building various contraptions over the years and even accidentally burned down his house at one point. Pictured above is a walking, talking rickshaw pulling robot he built to haul himself around town. You can see a
video of the mechanical man on Reuters
.
The design reminds us of [Bob Schneeveis]’
Schwarzenegger towed solar chariot
we saw at Maker Faire.

If you haven’t checked out SparkFun Electronics’ prototype collection yet, you’re missing out. They unearthed many of their old prototypes and published them to
show what kind of mistakes could be made
. You’ll see plenty of errors and get hints on what to look for while developing your own hardware. This pairs well with their
Design for Manufacture
post. Along with the pile of broken board iterations, they also walk through
how the company developed
. Finally, they specifically cover the
individual iterations of the BlueSMiRF
.
One of the interesting modules in the gallery that never saw full release was the SparkFun Toys line pictured above. The individual units used the standoffs as the power and data bus. The four posts were arranged so they could only be connected in one orientation: power, ground, TX, and RX. It’s an interesting idea that seems like it might be worth exploring further. SparkFun says that it worked fine, but didn’t feel they had the resources to market it to the intended audience.

Hand Made Triode

[Claude Paillard]
makes his own triodes
(
google translated
) for short wave radios. The site doesn’t have a lot of details itself, but links to entire books on the history of radio tubes and manufacturing of them. [Claude] takes us through the entire process of building a
triode
in a 17 minute long video. Even if you aren’t into them, this is fascinating. From the looks of it, several of us might only be a pump or two short of being able to cobble one together.

If you like the sound of the theramin, you may enjoy the
Ondestrak
. Based loosely off of the
Ondes Martnot
, the Ondestrak works by changing the pitch of a continuous note. [Devin_mccutchen] built his using an old
gametrak
controller. The controller looks pretty cool. We hadn’t seen that one before. Check out a more musical performance after the break.

When we saw this
giant home vacuum tube
, we thought it would go perfectly along side the
giant LED lamp
. Constructed from spare computer parts, a glass display dome and some EL wire, it is fairly convincing looking. If only he had shaped some characters with the EL wire, we could do a giant nixie tube project.

If “someone to test it” is an acquaintance from hospital, then it’s even more probable since those meters are specifically designed for x-rays. Of course one can stumble upon more specific counters for nuclear medicine, they might be gamma-only.Regarding that vacuum portion, I don’t think anybody understood.

M-CLE
, described as ” a physical learning environment in which synergistic artificial intelligence through the use of robots(creative agents) is employed to embellish the creativity of the child”, looks like a pretty fun toy. For those of you who haven’t figured out what it does from that quote, it is a toy that kids ride on to control a robot. That robot draws on the floor while other robots interact with it using AI. This is all made to “embellish” the child’s creative work.
To control the robot, a child rides on a Fischer Price Smart Cycle. The factory electronics were replaced with an ATMEGA168. A wireless transmitter connects to the robot, which is also powered by an ATMEGA168. While one robot is controlled by the child, the others are packed with sensors to allow them to interact with it. They use touch, ultrasonic ping detectors, and IR line detectors. You can see it all in action in the
video summary
.
The design is interesting, everything is bright and colorful, and the shark fins on the robots are a nice touch. We have to wonder though, with a toy to ride on, a robot to control, and 3 other robots to watch in wonder, is the child going to be too distracted to be very creative?

"content": "Project Development NarrativeBy Karan Kamdar – Author of this projectkaran@1martianway.comhttps://1martianway.comWhen speaking in terms of a personal project development experience, I would cherish this project as one of the most fruitful and amazing of all learning endevedors that I have undertaken in my academic career till now. I don’t exactly recollect how I went about conceptualizing the idea for this project. What I do recollect though are two things – the first being that of having a lot of personal support and embellishment from my committee members and second being the fact that this project was both ideated, designed, tested and demonstrated in an extremely short amount of time. The project realization was also not one without obstacles or uncertainties. In fact, given the number of unknowns that this project begged I feel fortunate enough to realize it in any given form.The first of these unknowns was to technically realize a toy bike as an embodied form of input to the system. With respect to the Fischer Price Smart Cycle Physical Learning System, I was uncertain whether the system could be tampered with in any given form. Fortunately, the toy’s assembly was straight-forward. A set of screws that allowed the bike to be assembled and dissambled along its cross section was the key to modify the bike. However, this was only the first step. The second step was to reverse engineer every connection that went in and out of the toy’s microcontroller circuit and match these connections with my custom circuit. It was an anxious moment to see what the mechanism was to steer the bike – it happened to be a simple potentiometer. It was more than an anxious moment to see what the mechanism was to get pedal acceleration data – it happened to be a simple IR sensor package that encoded the rotations. I was so amazed and excited with this knowledge that I worked straight 18 hours from there to finish the integration of the bike with my microcontroller. The risk had paid off, I had saved valuable time and I had a ready to demo embodied input to the system.However, I knew that I should keep up the good work and not slack off since this was only the first part of the project. I still had to begin work on constructing my four creative agents. Before starting work on them however, I recaptured some of the lessons from my earlier project. Robotic constructions require hardware and build time and they require software intelligence too. The former of these requires a combination of building your own custom constructions from scratch and ordering specific parts from specific vendors which have their own order processing and shipping times. The latter of these requires a lot of patient thinking and negotiation with your computer given hangups, crashes, power supply etc. Also there is always the case of getting stuck in a debug cycle where you just don’t know what piece of code has gone wrong.As regards to the hardware material for my project, I took the decision of using Expanded PVC (also called as rigid or foam PVC). The primary advantage of this material is that it has some great features – it’s strong, tough yet easy to cut and drill, non-conductive and aesthetically very appealing. However, the main disadvantage of it (and one that I had entirely not anticipated) is the fact that it is available in very limited amounts in colors other than black, white, gray, yellow and blue. Since I had color coded my agents in red, green, blue and black, the primary colors that were missing from my PVC collection were red and green and I needed to have these colors to keep the aesthetic of my project consistent (something that I realized is equally important other than the sole functioning of the project). I did call up several PVC vendors without success, finally at the 16th try I managed to personally request a vendor to have these colors shipped to me as soon as possible and my aesthetic was then complete.However, it was not just the bike and the aesthetic that I had to worry about.Karan Kamdar, [26.04.20 23:53]Several problems surfaced while just building the electronics and agent structure. With regards to electronics, there was a recurring problem of testing the performance of the agent in physical space using on-board rechargeable batteries. Since the drain on the batteries was primarily a function of how well I had written the code to efficiently utilize the power hungry ping, IR sensors and servos, there were multiple times when I had to neatly synchronize battery recharge times with code reconstruction and testing. Moreover, although I had relied on the quick wireless method of uploading code to the agents, there were many times when the TX / RX on the controller-Xbee interface would just halt. Thereby part of the code would get uploaded to the agents and I could not send them the reset command to reset their transistors. In this case, I had to disassemble the agents to the lower deck, take out the microcontroller, serially reprogram it, fit it back into the circuit and then go for wireless upload again.With regards to the agent structure, I guess there were two problems that I was worried about. The first was governed by the need of minimizing the space occupied by the agent in the design space. Since I had a 6 feet X 6 feet space to operate within, I had roughly calculated a base diameter not exceeding 7 inches. Within these 7 inches, I had to fit two drive servos, a ‘centered’ marker assembly (overlapping which was the screw to tighten one of the two skids that allowed the agent to be supported on two wheels), the microcontroller circuit, feelers – the arrangement of which did take some optimization. One of the foundational decisions though was that of adding the Ping sensor and its mounting bracket for which I had zero room left on the base deck. So I jig-sawed a quick piece of expanded PVC to extend the base deck, the concern in mind being if the weight of the front servo and ping sensor assembly would be supported adequately by this small piece which was already extending the design requirement of 7 inches. Fortunately, that decision turned out to be the best one that I took since during actual runs, the performance with feelers alone would only be satisfactory. Frequent collisions would be so disturbing that the agents would be more busy in conflict negotiation that actual creative work. Adding the ping sensor assembly that allowed the agents to keep a distance of 6 inches between them was thus very crucial. The second of the problems with respect to the agent structure was the agent’s center of gravity being proportional to the number of decks installed. I was concerned of the agent tipping over if I loaded the second deck with batteries and then the third deck with the equally important shark fin that allowed for a sense of direction to be attributed to the movement of the agent. Fortunately, the combined weight on the servos was well distributed and my agents were well balanced and composed for their creative act.Wow!…. So many problems just come along your way and keep testing you until the very end. But these problems and the unique solutions that we discover for them is what a learning experience is finally all about. And many times there are important things that have happened, ones that you just don’t recollect while documenting your experiences. In my case, the above subjective description is thus only a subset of the sheer number of do-it-yourself, try, fail and succeed sort of things that happened during my time at ACE. Its been such a wonderful, wonderful learning experience that a symbolic mode of documenting them indeed seems vicarious!I feel a sense of tremendous satisfaction with the completion of this thesis and project and greatly acknowledge the personal embellishment of all my committee members. Even though I failed too many times, all those failures were critical to my learning experience. It was the process and not the end result that mattered. This process has tought me important lessons and skills and I look forward to the future with a deep sense of gratitude and a positive mindset.Thankyou again to my committee and all those who have supported my work.",

This process has tought me important lessons and skills and I look forward to the future with a deep sense of gratitude and a positive mindset.Thankyou again to my committee and all those who have supported my work.",

[ghostwalker] dropped in on our
previous Debian Android post
to let us know that he had
streamlined the install process
. The first time around, it quickly became difficult to complete the process because firmware updates had taken away root access. Hackers have since figured out how to
downgrade from RC30
and
install BusyBox
. All you need to do to put
Debian
on your phone is download the package from [ghostwalker] and then run the installer script. This isn’t technically a port since Debian already has ARM EABI support. What would you run on your
phone
if you had access to the entire Debian package tree? A video of Debian starting up is embedded below.

Cadsoft Eagle
is a multi-platform freeware circuit layout program. Lots of open source hardware is designed in Eagle, and it’s become a hobbyist favorite. We use it for all of our
hardware designs
.
There are several ways to turn an Eagle design into an actual
printed circuit board
(PCB). We’ll show you how to save Eagle designs as industry-standard gerber files that are accepted by any PCB manufacturer. You can use the gerbers to order a single prototype, or a full panel.
Introduction
Toner transfer is the beginners’ favorite way to make a PCB because the investment in materials is minimal. We’ve
covered toner transfer before
. Most PCBs in our
how-tos
are made with the
photo-resist process
. The photo process makes nice boards, but requires a bit of equipment; sensitized boards, developer, and an ultra-violet light source.
Some board manufacturers, like
Olimex
, make PCBs directly from Eagle .brd files. Most require a minimum order of one
eurocard-sized
PCB (100mmx160mm). Good if you need a few boards, expensive for a single experimental prototype.
The cheapest option is to submit
gerber files
like the professionals. Any PCB manufacturer will accept gerber formatted design files.
Gold Pheonix
sells 155square inches of PCB panel for $110. If you’re looking for something smaller, services like
BatchPCB
and
PCB-Pool
combine small orders and submit them as a full panel. Either way, you’ll submit gerber files to the board house. This is the process we describe.
Process overview
Prepare the design.
Create gerbers, generic files accepted by any PCB fab house.
Verify that the gerbers are correct.
Send the design for production.
Prepare the design
We’re going to walk you through the process of preparing our
digital picture frame
PCB for production. This design requires a double-sided board with fairly small traces.
Download the
project archive
(ZIP) from last week. Open the .brd file with the freeware version of
Cadsoft Eagle
.
The ground fill is empty when the file opens. Press the ratsnest button (
or Tools->Ratsnest
) to fill in the empty polygons.
Board manufacturers publish specifications outlining their production capabilities, such as the smallest possible traces, spacing, and drill size. BatchPCB has 8mil
minimum traces and spacing
, and 20mil minimum holes.
Don’t torture the manufacturer. Just because they advertise 8mils, doesn’t mean it’s safe to make every trace 8mils. Slightly larger-than-minimum tolerances will reduce
manufacturing errors
. The digital picture frame has 8mil traces around the tiny
LCD connector
, shown above. The traces are 8mils only until there’s enough clearance to use 10mil traces.
Use Eagle’s
design rule check
to make sure your board doesn’t exceed the manufacturer’s production abilities. Download the
SparkFun design rules
(DRU) for BatchPCB, or the Olimex
8mil
(DRU) or
10mil
(DRU) design rules. Click the DRC icon (or,
Tools->DRC
) and load the design rule file. Eagle analyzes the design and highlights any areas that violate the design rule parameters.
Correct any errors. Here, the spacing between traces is too close. Sometimes the spacing on a part footprint is too small to be manufactured. Sparkfun’s default footprint for the Nokia LCD connector had pad spacing less than 8mils. We
edited the part library
to make the pads smaller, and the separation larger.
It’s helpful to include part numbers on the printed silkscreen layer. BatchPCB prints a silkscreen on both sides. Be sure to see what your board house offers, some charge extra. Use the smash tool to unlink obscured labels, then move them to a better location.
Create gerber files
Gerber files are the
PDFs
of PCBs. Gerber files describe a PCB exactly as it should appear, agnostic of the display hardware. It’s a final production format that isn’t intended to be edited. We created our gerber files in Eagle using the procedure outlined in
SparkFun’s Eagle tutorial
.
The Eagle CAM processor writes gerber files, open it from the menu under
File->CAM processor
.
SparkFun has a
script
(CAM) that configures the CAM processor to make gerber files. Load the CAM script using
File->Open->Job…
By default, SparkFun’s silkscreen configuration only includes the
place
layer. Our parts usually have labels on the
names
and
docu
layers, activate these layers on the top and bottom silkscreen tabs to add them to the output.
Click
Process Job
to create the gerber files.
The CAM processor creates seven files that we need.
Top and bottom copper (.GTL, .GBL)
Top and bottom solder mask (.GTS, .GBS)
Top and bottom silkscreen (.GTO, .GBO)
Drill file, 2.4 leading (.TXT)
Verify that the gerbers are correct
Verify the CAM output in a
gerber viewer
to make sure everything was positioned correctly. We followed SparkFun’s suggestion and used
Viewplot
.
Load the seven files with Viewplot.
Be sure to specify the drill file type as 2.4 leading.
Check for errant vias, mirrored layers, and alignment. We’ve noticed that text added to the silkscreen layer is usually bigger than it was in Eagle. Correct any problems and run the CAM processor again.
When everything looks good, the board is ready for production.
Send the design for production
Zip
the seven gerber files and submit them to the PCB fab house.
Remember to tell them that the drill file format is 2.4 leading.
BatchPCB is a pooled panel service that sells space by the square inch. Other manufacturers and batch services require you to order
at least
a full eurocard. We use BatchPCB for prototyping because we never need the extra board space of a full eurocard, and we don’t mind the average 20day wait.
At BatchPCB, $2.50/square inch buys a PCB with silkscreen on both sides, unlimited vias, and a huge range of drill sizes; stuff that usually costs extra. BatchPCB’s minimum traces, spacing, and drill are similar to other prototyping services. There’s a $10
per order
setup fee, but an order can include multiple designs. Shipping, even internationally, isn’t outrageous.
If you need a lot of the same board, look at Gold Phoenix. They manufacture boards for BatchPCB. A 100 square inch panel is $100, a 155 square inch panel is $110.
Create an account at
BatchPCB
. Click upload to add a new design. Name the design and upload the zip archive containing the 7 gerber files.
Verify that the gerber layers were successfully detected.
Verify that the correct size was detected.
The BatchPCB rule check ‘robot’ will verify that your design meets production standards, and send an e-mail in a few minutes. Since we ran our own rule check prior to sending the design, we can expect that everything will be fine. Click continue and you’ll have the option to order the board. For more help, see the BatchPCB
help
and
support forum
.
Receive your boards
Boards arrive from BatchPCB in about 20 days. Check the boards for obvious errors before soldering. Some manufacturers test PCBs, BatchPCB doesn’t. We’ve ordered PCBs from two of the popular hobbyist board houses, Olimex and BatchPCB, and all the boards have been satisfactory.
Taking it further
It’s easy to order professional PCBs using gerber files. Why not build that awesome DIY project you’ve been putting off?
What has been your experience with PCB fab houses?
UPDATE: the files have been moved!

Say $500 to $550. What is the point of this? People will just order much more quantity than needed and the fab is screwing themselves over in labor costs + environmental impact IMO.The only place I’ve dealt with so far that has a reasonable pricing structure for 4+ layer proto PCBs ishttp://www.myropcb.com. There is a NRE/E-test setup fee (~$200), and then a VERY reasonable cost per square inch for space + extras. Although if I am buying for the board myself, I’d probably go with 2 layer from gold phoenix :)",

Using the change feature is *not* an option because, often when I do this, the wider trace ends up coming into contact with another pad..It seems silly that I should have to manually route these traces and correct routing errors like this when I should just be able to tell it how wide to make the trace and let it go.

Out of all of these, Eagle is the most convoluted reverse polish notation EDA software out there. I suspect the reason why it has caught on so much over the years in the hobbyist market is the price and feature set. In the past, the other free contenders (Kicad & gEDA) were too early in there development to easily get any real work done. I’ve tried Kicad again recently and it is getting much better. It is still a little lacking in the area of power planes. I would bet that in a few more Revs, it is going to start catching on as the best open source, multi platform, free EDA software available. I will admit though that the Eagle following has produced a huge amount of parts libraries though.",

One big one is that different CAD and CAM software (and manufacturing equipment for that matter) may process and display it differently. So, what you see on the screen on EAGLE might be very different than what the manufacturer sees if they use, for example, CAM Master. So, *and I can’t stress this enough*, make dang sure that you and the manufacturer share a common view of how the PCB should look. One way to do that is to generate images fromhttp://www.circuitpeople.com, another way is to use the viewer recommended by the manufacturer (e.g. GCView, GView, GerbView, etc.). Both olimex and batchpcb are “build per files” services — meaning they aren’t going to fix your design for you. They probably won’t even look at it. For a higher level of service, yes at a higher price, a company likehttp://www.sunstone.comensures that every design is looked at by a person before it’s built — a nice safety net for the lazy/busy (like me).",

Actually running off boards is very cheap, but creating the tools (masks for the various layers) is relatively expensive. I think the reason this isn’t a big issue for BatchPCB etc. is because at a local fab house they will create a small set of masks specifically for your board while BatchPCB will make one big one with many designs, spreading the cost.That’s the tradeoff if you want decent turn times. Some fab houses will keep your tooling around and give you a cheaper rate if you want more copies of a previously produced design as well, which is a nice bonus.",

Researchers at Tokyo University of Agriculture and Technology have been
demoing a new power suit
. It’s intended to be used by people hand harvesting in the farm industry. The 55 pound device supports the worker’s joints as they squat and reach. Within three years, they hope to have the cost within $10K. We’ve seen quite a few power suit devices this year, but research has been going on for many years, as you can see in our
power suit roundup
.

Smart Attic Fan

[Andrew] lives in Hawaii where the climate usually doesn’t necessitate heating and cooling systems. Usually, some open windows and doors will cool the house down enough. This relies on the breeze though, and that isn’t always there. [Andrew] came up with the solution of
automating an attic fan
to circulate air depending on outside temperature. Sure, he could have just installed a fan with a switch, but he wanted it to do all the work itself. He used a PIC16F877 as the brains and made the pretty control panel shown above.

Tape Measure Generator

Caleb Kraft

"generator"

[Dr. West] wanted to do his small part to help save the planet. He has built a
small generator from a stepper motor and a tape measure
. The tape part of the tape measure was replaced with some cord. The spring loading mechanism makes the string re-wind automatically, which is nice. He shows it attached to one leg, with the string tied to the other, generating power while he walks. This is cumbersome, but seems fairly effective. You can see him waking around in a video after the break. Would this benefit from a flywheel or friction drive to keep the motor spinning after each pull? How can he rig it to feed off of the motion of only one leg to avoid tripping hazards?

The team at
oomlout
has continued to post all the methods they use in their manufacturing process. This time around
it’s the kitting process
: how they actually packaged 30 identical
SERB
kits in an efficient fashion. We covered their
wire cutting bot
before, but they’ve got other dedicated machines like a
sticker cutter
. The stickers are used to remove all the cut acrylic pieces from the laser cutter as one unit. They’ve got some other tricks like using a scale to count bolt quantities, and an egg timer to keep track of the laser cutting. All of their envelopes are printed using a parallel port inkjet that has been modified to work with any thickness paper.
We love when hackers bother to post this much detail about their process. One of our favorites is [ladyada]’s full rundown of
how the Minty Boost was created
.

Defcon Calls For New CTF Organizer

Kenshoto
, organizer of the official Defcon
Capture the Flag contest
for the last four years, has stepped down from the position, and thus Defcon is
looking for a new organizer for the event
. If you’re highly competent, and maybe a little crazy, this might be your chance to step in and run one of the most well-known and prestigious hacking contests in the world. Please understand that the staff is looking for someone who wants to take ownership of the contest and make something new, unique, and challenging, and that Kenshoto has left
extremely
huge shoes to fill. Merely offering to replicate the existing contest and keep things mostly unchanged isn’t going to cut it.
If you’re up to the challenge, check out Dark Tangent’s post on the Defcon forums (which, for some odd reason, sounds strikingly like his
2005 post calling for a CTF organizer
), where he comprehensively lays out what the staff is looking for in a new event organizer. If it jives well with you, get in touch with the Defcon staff, and maybe we’ll be covering your contest later this year.

Have you ever wondered how they inspect high voltage cables without taking them out of service? Check out this
video
which offers a glimpse into the life of a professional high voltage cable inspector. There are parts of the job you’d expect—namely perching on the cable like a bird, trying to not fall off—but the part of the job you wouldn’t expect is the suit. This suit is made of 75%
Nomex
, to prevent it from catching fire, and 25% stainless steel thread, turning the suit into a wearable Faraday cage. Of course, because he’s got a Faraday cage mere millimeters from his skin, the cable inspector spends his workday surrounded by half a million volts. To avoid electric shock, he equalizes the voltage potential between himself and the line before touching the cable.
Depending on your specific phobias, this video might make your job seem really dull… or really really safe.

Interview With An Adware Author

Philosecurity has an
interview with [Matt Knox]
, a former coder for Direct Revenue, an adware company which was sued in 2006 by New York governor Eliot Spitzer. The interview contains some interesting details of how the adware code worked internally: it created a Browser Helper Object, then ensured that the Browser Helper Object stayed up by creating a poller to check every ten seconds and regenerate the Browser Helper Object if it had stopped running. The poller ingeniously masked itself partly by exploiting Windows’ Create Remote Thread function to run itself as a series of threads instead of as an executable.
The truly fascinating bit of the interview is how [Knox] defies your initial suspicion that he’s a complete scumbag; he started off writing spam filtering software, was hired by Direct Revenue to do traffic analysis, started writing tiny bits of code to improve the adware, and eventually wound up knee-deep in the code. [Knox] notes that you can get ordinary people to do incredibly distasteful things if you break those things into small enough chunks and introduce them gradually.

Apple Forces Wired To Take Down Netbook OSx86 Video

Wired Gadget Lab
has taken down a video made by [Brian X. Chen] in which he gives a brief overview and demonstration of how to install OSX on an MSI Wind
netbook
. This apparently didn’t sit well with Apple, who contacted Wired and complained; Wired agreed and removed the video. Frankly, we’re disappointed with Wired’s response. While they were technically posting content which is questionable at best—in the video, Brian mentions that this is illegal and that it would be a good idea to have a retail copy of OSX on hand, but then goes on to point out that you can also download the hacked operating system off The Pirate Bay, Isohunt, etc—the video in and of itself wasn’t illegal, and thus Wired comes off as susceptible to what amounts to bullying by Apple. We’re all about creativity and innovation, and stifling that innovative spirit has never worked well in the long run.
Fortunately, if you’re feeling like you’ve missed out on the video, don’t despair: Gizmodo has
posted the video on their website
for you to view and enjoy.

Hack A Walkie Talkie For Music

[nepheron] shows us how he
hacked his walkie talkie to broadcast music
. While using this to broadcast music is
possibly illegal
, it could be used to make actual upgrades to your system as well. He has replaced the microphone input with a headphone cable and extended the antenna. It is only mono, and he states it will only run for a minute before shutting off, so there is definitely room for improvement.

And then he puts it all in a plastic bottle or some reason.Oh, and the thing only works for about 1 min at a time before it stops broadcasting. The reason is because he never bypasses the circuitry in the device that cuts transmission in cases where the “talk button” is pressed down for longer than 60s. Doubt he would no how to address the issue.Oh, did I mention that the transmit button is operated with a zip tie?What a waste of time watching. I mean, it’s cool I guess if people who are just getting into electronics and hardware want to dick around with something, but why did this lame project get posted to this site?What would be cool is if he used two off the shelf cheap walkie talkies and built his own packet radio transmitter/receiver and then broadcast a video stream over it.

I used the port for the headset on my walkie talkies so I didn’t even end up ruining the walkie. I also turned off my walkie’s auto-off function (which, I assume this one doesn’t have the option to do) so it didn’t stop. The distortion on these things is unbearably awful, unless you want a lot of distortion on a guitar (which I used mine for).Strangely enough, “Red Flag” by Billy Talent was one of the first (and only, because the whole idea of using walkie talkies blew) songs that I played through my setup, and it is being played in that video.",

It’s cheap (the test only costs $20 here in Canada) and you have access to a HUGE amount of the spectrum. You can use morse code, set up a packet radio network across the country, try out amateur TV, or just chat with somebody across the world in the wonderful hobby of DXing.

[thecapacity] sent us his iobridge project where he
controls a coil gun with a Wiimote
. To make the coil gun, he took apart an office golf putter that had a ball return. The mechanism to return the ball is a metal cylinder that is moved magnetically. He simply replaced the cylinder with a smaller diameter piece of metal to create the gun. His computer monitors the Wiimote axis changes and sends them to the ioBridge. The unit could be located anywhere, but without a camera on it, he’ll have a hard time aiming. There’s a video of it working after the break.

My platform is two “mustard scoops” (I think that’s what they are) that we had in the kitchen from some Bed Bath and Beyond shimpments!@sean I didn’t show it in the page but I have the wiimote’s trigger initiate an iobridge event also. I’ve ordered a relay board to isolate the firing sequence from my board’s electrical system. But for now that’s straight wall current powering it so I thought it was better to be safe then sorry!

The WiiMote daemon I used spits out the data constantly, and I learned (from watching the data) that accelerometers aren’t all that “perfect”!You’ll get a value say 124 and it’ll ficker b/t 119, 128 and maybe a few others (and these are all floating points too!).Also it makes sense once I saw it but if you move the wiimote, say left, you’ll see a spike in #’s but hold steady for a second and it’ll look like it never moved! (This is because accelerometers can only track inertia and that’s why there’s an IR sensor too).I have a new found respect for all the math behind it all! If your program blinks for a second you could have missed a movement! And I have no clue how to extrapolate 3 axes into something simple like a “gesture” for now!Anyway, it sounds like maybe you’ve got enough to try more of a mechanical system and if you’ve got some good servos maybe use them to wind a trebuchet, crossbow / windlass or something!Or if you can gear it up how ’bout one of those centripetal acceleration cranes like they use for pumpkin’chunk’n!I think I saw an image recognition hack on here maybe a year ago where a guy could shoot his buddy w/ a paintball gun!Good luck w/ the nokia, but if it’s too tough a wiimote’s pretty cheap for all that it does (think about all those buttons! ;> ) and let me know if you want some ideas (as you said from my site, I’m full of ’em ;> )",

I did a project a few months back using an accelerometer and magneto-inductive sensor to determine 3D orientation, and believe that you can get much better reading from reading 2 axis and calculating the angle of the gravity vector to determine the controller’s roll. If you’re only reading one axis, it tends to be over-sensitive around the midpoint.Another idea you may want to consider, is to mount the Wiimote on the coilgun. You could then paint the target with a IR laser, and use the Wiimote’s IR sensor to track the target. This way, you don’t need to be at the computer to aim it using a webcam.",

[Matt] sent us this very cool looking project called
Illuminato
. After brainstorming on how to improve upon the
Arduino
, and receiving lots of input on his ideas, [Matt] has put together this board that has several nice improvements. It has more I/O, more code space, faster serial communication speeds, built in PWM, and works with existing Arduino shields. Not only does it make these improvements, but it does it with style. The finish is quite nice, the layout is pleasing and it even has two rows of SMD LEDs on the back for some added geek cred. You can see a couple videos of it in action after the break.

Recently, a Japanese coder on the DCEmu Forums released Windows drivers for DualShock 3 controllers. While the drivers only support using the controllers over USB and not bluetooth, they do include force feedback and Sixaxis support. Included with the drivers is a configuration tool, and though it appears to be in Japanese there is some explanation of how to use it included in the forum post. We have not tested these personally, but you can try out the drivers for yourself by downloading them from the forum
here

The 360 and dualshock 2 and 3’s are pretty clearly a form of force feedback.Wikipedia disagrees with you by the way:Computer and video gamesSome simple haptic devices are common in the form of game controllers, in particular of joysticks and steering wheels. At first, such features and/or devices used to be optional components (like the Nintendo 64 controller’s Rumble Pak). Now many of the newer generation console controllers and some joysticks feature built in devices (such as Sony’s DualShock technology). An example of this feature is the simulated automobile steering wheels that are programmed to provide a “feel” of the road. As the user makes a turn or accelerates, the steering wheel responds by resisting turns or slipping out of control. Another good example of this is Guitar Hero’s guitar controller. The Wii wireless remote uses a simple “bump” for feedback (e.g. moving over an onscreen button).",

Putting FD Lenses On A D60

[Peter] sent in this really slick project where he ads an
FD lens mount to a cannon EOS D60
. He already had a collection of nice lenses and didn’t want to waste them. After finding some a donor camera for the
FD mount
, he purchased a cheap D60 to graft it onto. While his first impulse was to simply glue the new mount onto the front of the camera, it was evident that this would hold the lenses too far from the sensor. The camera went under a bit for a while and luckily, no real damage was done to the mirror housing. The final result seems to work very well, there are
example galleries
available on his site.

The
N8VEM
is a homebrew computer project based on the classic
Z80
microprocessor. It’s designed to be easy to build using large TTL DIP components instead of SMD devices. It runs the
CP/M
operating system and all drives are virtual in RAM/ROM. While the base hardware is interesting, we really like the potential for expansion using a backplane. Have a look at the project’s
Hardware Overview
to see extra boards like the bus monitor and the prototyping board. We found out about this project on [Oldbitcollector]’s blog; he’s using a
Parallax Professional Development Board
to create a
VT100 terminal for the N8VEM
.

I’m in Australia – that photo was taken in the USA. The board on top is a single board CP/M machine with onboard 448k of static ram configured as an A> drive. I know lots about that bit. There is plenty of room for Wordstar and Mbasic and Supercalc all at the same time. Plus a few games. The bit in the middle I think is a roll of solder. Down the bottom is a propeller board acting as a terminal. I’m not quite up with how that works except that it drives a vga terminal directly and has a keyboard. Since this photo was taken, the next generation has 4 serial ports and has wireless links. The generation after that will probably have the propeller chip on board so then it will be a true single board. And already someone has emulated most of the 8080 code inside a propeller, so within 6 months we could well see the whole computer inside one 40 pin chip. That is a single chip computer running CP/M with wires that connect to a VGA monitor, a keyboard and a wireless module and an RS232 port and an SD card for mass storage.

[jefffolly] published some straight forward plans for a
passive volume control
. It uses a resistive ladder built across the contacts of 12W rotary switches. Each resistor provides a 5dB difference, and he recommends using 0.1% tolerance resistors to maintain accuracy. The use of discrete resistors instead of volume pots means that the output is much more predictable. All of the RCA sockets were connected using oxygen-free copper wire.

[John] has been working with several
BlinkM
RGB devices. He’s created a
controller to talk to each of the BlinkMs wirelessly
and change their behavior. The core is an old relay tester box used to test telephone circuits. Each of its four knobs are connected to the analog inputs on the Arduino. The signal is transmitted using RFlink devices. Each BlinkM is paired with an ATmega168 and receiver. The control box also has a switch to send the same signal to all of the devices at the same time. The transmit and receive code are available on his site. You can find a video of it embedded below.

The RepRap project has made heavy use of the
Solarbotics GM3 Gearmotor
as part of their extruders. Unfortunately they’ve proven to be underpowered for the task and the plastic gears could cause future problems. [Zach] decided to investigate some other options. He
bought a pile of motors
from Kysan to try out. He posted a
teardown of one of the motors on Flickr
. He found it not only easy to disassemble, but the metal gears were also easy to put back together. Next up is testing it on the machine.

ArtFall
allows you to draw on a whiteboard, then have small geometric shapes interact with your drawing like a barrier. Imagine a
pachinko machine
where you have to draw the pegs in. Not only can you draw barriers, but you can change the direction of gravity with either an
iPhone
or a Wiimote. The footage also shows some sound interaction as the pieces seem to bounce with the bass from some music. The effect is quite nice and somewhat reminiscent of the
whiteboard pong
we saw recently.

Hacking A Digital Picture Keychain

The Coby DP-151sx Digital picture frame keychain seems to be
ripe for hacking
. At
roughly $9
, you get a screen, and Li-Ion battery. That’s not bad considering a
similar screen
alone would cost $20 elsewhere even though it runs on a slower serial connection. While they’ve only put a 3 color pattern on it so far, more can’t be far behind. If you don’t feel like actually tearing it apart, there are
some projects that have managed to customize what it displays
via the USB connection.

[Eric Archer] constructed an analog computer to
model the physics of a bouncing ball
. The core is a TL074 opamp that does all the integral math. He had no trouble finding descriptions of analog computers, but how to set the initial conditions was rarely covered. The controls include potentiometers to set the initial velocity, force of gravity, and coefficient of restitution (how much energy is lost in the bounce). The output is displayed on an oscilloscope. He mentions that this output could be used in electronic music, citing
Aphex Twin’s Bucephalus Bouncing Ball
. Watch the video below for a demo of all the features.

UIRemote: Universal Remote Application For IPhone

When several students from the University of Toronto became tired of having multiple remotes lying around, they decided to do something about it. Their solution to this problem came in the form of
UIRemote
, a universal remote application for the
iPhone
. The application allows the iPhone to control anything that is normally controlled by an infrared remote, thanks to the use of a custom infrared adapter that plugs into the phone’s headphone port. It’s a technique similar to our
iPod remote control
from 2004. While the UIRemote application and adapter are still in beta, the students expect to release both things simultaneously sometime within the next two months.

On the off chance that you want to
program a microcontroller to play your games for you
, you should check this out. Near Future Laboratories has made a dongle that can allow an Arduino to operate as a
PS2
or
PS3 controller
. You can see the Arduino running a random path generator in Katamari Damacy in the video above. They wanted to see how long it would take to clear a room. It managed to get almost all of them in about 70 minutes, only missing those that you have to cross a narrow bridge for. Actually, this could be quite useful in allowing people to create alternative input methods. You may recall reading about their
early progress
back in June 2008.

Brute Force Attack On Twitter

Wired Threat Level has posted an
interview with the hacker who recently broke into several high profile twitter accounts
, such as Fox News, and Barack Obama. Since we know how much
you all love twitter
, we thought you might want to learn more about it. Apparently he used a brute force method to get into a member of the support team. The password was “happiness” which was cracked pretty quickly. This might be a good time to review your own
strategies to prevent brute force attacks
.

If you’ve ever been curious what it is like to work at ThinkGeek, check out this video. [John Frazier], a purchasing agent,
talks about the history of ThinkGeek as well as what daily work is like
. Fairly interesting, but the summary is that it’s just like any other job, with more toys. They probably have to
test all the products
fairly thoroughly, we know we would.

Autoblog
dug up
this classic mechanical engineering project from 2006. A team of five University of Toledo students constructed a system to help parallel park a car. First, you drive nose first into the space. Hydraulic rams then lower the drive wheel out of the trunk, raising the rear of the car. The single wheel is also hydraulically driven and moves the car into the space. They have a
blog documenting the six week build
. Have a look at the demonstration video below.
