Palette Gear: Hands-on Control of your Favourite Software Starter Kit Get up and running with the starter kit and add modules as you need them Expert Kit A versatile kit for most users. Switch between profiles to assign even more functions Hijack Introduction HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices.
The Original Egg-Bot Kit [KIT11072M] - $192.50 The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to that of a small grapefruit-- roughly 1.25 to 4.25 inches in diameter (3 - 10 cm). The kit is based on the original design by Bruce Shapiro, dating back to 1990. Our version, the "Egg-Bot 2.0," is a modern and friendly update, designed with the assistance of Bruce and his team. The Basement Lab for Computer Vision and Personal Robotics This is The Basement Lab for Computer Vision and Personal Robotics’ June 2013 status report. Here I present status and progress for various tasks and my goals for the next phases as well as my hardware acquisition plans. Continue reading In previous posts, I presented new hardware I acquired to build an Arduino robot and preliminary component testing.
Notes: Arduino-based logic analyser by follower - labradoc.com The process of getting an Arduino-based logic analyser working Download the current source from the repo: wget --no-check-certificate --content-disposition Should result in a file named something like gillham-logic_analyzer-c923ff1.zip. Then: unzip gillham-logic_analyzer-c923ff1.zip Install the OLS GUI application. Install the plugins as per the README file.i.e. copy the ols.profile-*.cfg files into the plugins directory.On OS X the plugins location should be: LogicSniffer.app/Contents/Resources/Java/plugins (Use the Finder context-menu option "Show Package Contents" if not using the command line.)
How to make an open hardware monitor-like device for your heart A few weeks ago, my doctor told me to keep an eye on my heart with the help of DIY toolkit BITalino, and I wrote about it in Why my doctor prescribed me open hardware. Although I could keep slapping a bunch of cables and a PCB on me every day (Figure 1), miniaturized physiological computing devices are pretty fun to build and play with—at least for me—so I decided to make myself something more practical. As this project may be of interest for others, I wrote this tutorial explaining the making of CubiKG, a Holter monitor-like device for heart and activity tracking.
Build A TENS Machine to Remove Pain A Tens machine is used to provide a drug free way of removing pain from your body ( TENS stands for Transcutaneous Electrical Nerve Stimulation ) .Here I will show you how to build your own Tens machine and reduce the amount of pills you use to stop pain .To Build this Tens unit, you will first need to buy a 555 timer IC . The 555 timer is very small about a quarter of the size of your finger nail .You can purchase one for about 25p from Maplins or Radio Shack etc . There are 2 types of Tens machine. High Frequency Tens uses frequencies in the range of 80 to 100 Hz. Turnigy 9X 9Ch Transmitter w/ Module & 8ch Receiver (Mode 2) (v2 Firmware) With v2 firmware update, correcting many flaws of the previous 9X, plus inbuilt 2.4Ghz (no daggy second antenna) this is a quality, reliable 2.4Ghz system suitable for beginners and pro pilots alike.Get that locked-in feeling that only 2.4Ghz glitch free technology can provide.Ultra fast reaction times and interference free control of your model is only achievable with this 2.4Ghz technology. Without a doubt, the best value 9Ch system available!

Cheap 2-Way Bluetooth Connection Between Arduino and PC In the guide, I will explain how I managed to send data back and forth between a PC and Arduino via a cheap Bluetooth HC-05 transceiver, which can be found for less than $10 on ebay with the breakout board. The version I have used in this project does not have a breakout board so it's little cheaper but more difficult to solder. I strongly recommend buying the module with the breakout board. This Bluetooth transceiver basically acts as a generic serial COM port. The PC to Arduino Bluetooth serial connection can be useful in many applications such as controlling servos, motors, and writing to LCDs. The Arduino to PC connection can be useful in applications where the Arduino reads sensors then pass their values via serial Bluetooth to a PC for processing.
OLS - alternative Java client Welcome to the project page of Logic Sniffer Java client. This page will provide some documentation and, of course, download links. Table of contents Introduction DIY ECG Machine On The Cheap Note from the Author: This page documents how I made an incredibly simple ECG machine with a minimum of parts to view the electrical activity of my own heart. Feel free to repeat my experiment, but do so at your own risk. There are similar projects floating around on the internet, but I aim to provide a more complete, well-documented, and cheaper solution, with emphasis on ECG processing and analysis, rather than just visualization. If you have any questions or suggestions please contact me. Also, if you attempt this project yourself I’d love to post your results!
OLED panel could switch between sunroof and light source A sample of the OLED roof panel material, that can switch between being transparent and emitting light Image Gallery (2 images) What if your car had roof panels that let you see the sky during the day, but that lit the interior of the vehicle at night? This is now a distinct possibility, thanks to work being done by BASF and Philips. As members of a consortium assembled by Germany's Federal Ministry of Education and Research, the two companies have created OLED panels and installed them in the roof of a car. When switched on, the panels glow, lighting the cabin of the car - when switched off, they simply go transparent.
CrazyCopter « Daedalus Projects As promised, we publish some more information about CrazyFlie, our first quadcopter. The main architecture of the system is as follow: The copter itself is organised around the main CPU. The job of this CPU is to acquire the physical measurement given by the gyroscopes and accelerometers and to control the motors to keep the copter stable. This is done by a regulation loop which controls the motors speed 250 times per second. Building an Arduino Robot, Part I: Hardware Components I have been doing software for almost as long as I have memory. I have also been following the open source hardware movement since its inception a few years ago, but I have never found the time or the disposition to attempt a hardware project myself. Until now, that is. I have decided to do a small hardware project to get my feet wet, a project that I will fully document and discuss here with the hope to encourage and motivate others to do the same.
