Bruce writes – “Students were given the responsibility of choosing a microcontroller project, then designing and building it. This year’s projects include an RFID reader, swing robots, an autonomous helicopter, and an 8-channel music controlled fountain.” – Link.
Leoricksimon sent in his lab power supply project, we’ve covered a few here, but this is one of the best – “Make your own lab power supply complete with adjustable voltage with presetable constant current. Using single LM324 op amp and stripboard layout included.” – Link. Previous: Lab Power Supply & more – Link.
Jeff writes – “Here’s my first stab at an electric powered vehicle – A plastic Adriondack chair from Target, with headlights, keyed ignition, speed control in the pistol grips, foot pedal steering, under armrest neon lighting etc. Cruises the neighborhood at about 12mph. Surprisingly comfortable with aircraft (rudder) like steering footpegs.”
John writes – “Here’s how to add a wired remote control (like Pioneer SR) jacks to VCRs and DVD players that don’t have any.” – Link.
Alan writes – “What do you do when your hard drive dies or is so small it is no longer useful? Easy, rip it apart and make something cool out of it! Here are 5 ideas to get you started. See project VIDEOS and PICTURES. (Includes the never before seen Hard Drive Oscilloscope)” – Link.
Ian writes – “The goal of this project was to build an efficient Altoids tin iPod (firewire) charger that runs on 3 (rechargeable) ‘AA’ batteries. This project started out as a collaborative effort with Sky on PCB design and construction, and I on circuit and firmware. As it is, this design will not work. It […]
Len sent in this great clock (schematic at the bottom of the site) – “It’s actually a pretty simple circuit. The clock is based on an Atmel AT89C2051 microcontroller. The software in the microcontroller handles the count for the time. It “talks” to a 4 channel Digital to Analog converter to derive the voltage to […]
