"In the mining rig described here an FPGA does all the hard work (SHA-256 hashing) and communicates over a serial link with a Raspberry Pi. The latter requesting new work from, and submitting proof of work done to, a Bitcoin mining pool."

"The purpose of the prototype was to demonstrate the feasibility of a small, highly maneuverable search and rescue robot. As such, the completed prototype was successful. Capabilities include a ground speed of 10 inches per second, battery life of 50 minutes, wireless range of between 50 and 150 feet, weight of 14.5 pounds and the ability to climb stairs."

"In just a few hours of hacking and experimenting, we turned this radio-controlled car into a WebSocket-controlled car. Don’t worry, no actual cars (or bunnies) were harmed in the making of this demo, as you’ll see as we walk through the hardware and software we used."

"The USnooBie is a microcontroller kit that does not require any sort of AVR programmer or USB-to-serial converters to load and run compiled code. It’s hardware design allows the user to develop low cost USB devices with Atmel’s AVR ATmega microcontrollers. It can also be used to develop projects which are not USB devices. It is even compatible with Arduino."

"This easy-to-build electronic device allows you to take a screenshot of your calculator display and show it on an NTSC or PAL television set. Unlike the TI-Presenter this does not require a special calculator or a USB adaptor; it uses the 2.5mm link port."

"An interesting project has come up as a fund-raiser for BuildBrighton members – to ‘hack’ some alarm clocks and modify their behavior so that instead of playing a single sample when the alarm sounds, one of up to seven different sounds can be played."

"With the phasing out of game, serial and parallel ports from modern computers and the ever increasing popularity of USB, it makes sense that hobbyists start getting to grips working with USB….This project focuses on the use of a USB PIC and the mikroC compiler to convert an old game port joystick to utilize USB."

"My wireless temperature probes work by using an Xbee module to transmit readings from a TMP36 down to the Arduino base station…these take a voltage of around 3-5.5V as input and will output a voltage between 0-2.7V to indicate the temperature, which can be from -40 – 125°C."

"The heart of this project is PIC16F1847 microcontroller which receives data from a PC through a serial port, and display on the LED matrix with the help of five 74HC595 shift registers."
