Electronic Hobby Projects – Chemelec

This is one of the oldest Electronics DIY Project Sites in the Internet. I now discovered he has a dedicated domain too. Gary from Canada has many useful schematics and even provides kits and parts.

A Mos-Fet Power Inverter

A Mos-Fet Power Inverter

This circuit will provide a very stable “Square Wave” Output Voltage. Output Frequency is Adjustable and Stable. Can be used to deliver a wide range of output voltages by using appropriate turns ratio. Additional MosFets can be paralleled for higher power.

Sumo Robot project of Dave Chu

The following is my Computer Science project Comp490 and Comp492 in progress. It is a SUMO robot for our local RoboWar tournament. I have been, for the pass two years a participant of the annual RoboWar competition. So, this year I’ve decided to try to get credit for doing it.

“I was fortunate enough to find a professor who was willing to supervise my project Dr.Ferhat Khendek. I have decided to do the documentation in HTML format and make it public to anyone who is interested in robotics.”

There are two class of robots, remote controlled and autonomous. Remote controlled are operated by a human participant via RF link. Autonomous on the other hand has to be self contained with no human influence in its operations with the exception to its programming.
