"To the RC car I removed all the electronics except the motors and i installed 6 new AA 1,2V rechargeable NiMh 1900mAh batteries. I designed new electronics based on Arduino with a HC-05 Bluetooth module and two h-bridge ic’s. The SN754410 for steering motor and the L298N for forward/backward motor. For both ic’s i connected parallel the channels, 1 with 4 and 2 with 3."

"As a beacon, unmodulated white light sucks….So, what to do? After rejecting a few stupid ideas I finally got interested in using X-Band microwave signals as a beacon. Oh my. Sounds pretty intimidating huh. 10,000 mHz radio is black magic. Or is it?"

"A project I’ve been hacking on for a while is a self-contained 1-wire to IPv6 bridge based on an Atmel AVR ATmega644 and the ENC28J60 Ethernet controller from Microchip."

"This is 60 MHz frequency meter / counter for measuring frequency from 10 Hz to 60 MHz with 10 Hz resolution. The meter provides very stable readings and has excellent input sensitivity thanks to on board amplifier and TTL converter, so it can even measure weak signals from crystal oscillators."

"This is the fourth generation of colour organ that I have built and, unlike previous designs, uses entirely digital filtering for excellent frequency band separation – a natural for me since I developed a DSP course, CTEC1631, at Niagara College in 2005 for the department of Computer Engineering Technology."

"I thought it would be a neat to build a toy that records and plays back beats like a simple drum machine. For those who are musically inclined, it provides endless hours of entertainment and even has practical purposes in learning and practicing music. Even better if it used less than $5 worth of parts and could be built in 30 minutes."

"For the final project we have decided to create an inexpensive solar tracking divide to be incorporated wit DIY solar panels. Our goal is to create an open source project that is easy to follow and can be produced by anyone at a low cost."

"After being a member of PING for a while I got more and more interested in electronics and microcontroller programming. As I didn’t own a standalone digital clock, I decided to make one myself. We had all the necessary components: Seven-segment displays, a microcontroller and appropriate resistors."

"Arduino-based project to create power strip driven remotely through an Ethernet network. To turn outlets you are connecting to the microcontroller via telnet and after entering a password, you can change the status of the main lines and see if they are on or off."
