Fan Powered RC Car

Chris Dycus | May 29th, 2008 | 3 Comments

This is an RC car I built. It’s pretty quick, as you can see in the video. It’s easy to build, despite its complicated looks. Here are the basic steps:

Cut a base out of balsa wood, making sure to cut away parts for the front wheels.

Mount the front wheels, including the servo.

Mount a fan on the back wheels and mount those.

Rig up a servo arm to press a switch; that will be the GO button. Have that switch turn a relay, which then feeds power from the main battery to the fan. Mount it.

Mount the relay battery and the fan battery.

Mount the receiver, and hook up the servos.

Attach the batteries for the receiver.

And that’s about it! Thanks for reading.

Home Made Answering Machine

Throughout the years, I’ve built a lot of offbeat things from found objects and RadioShack parts. I wish I had taken pictures of the telephone answering machine I built in the late 70’s. It took up an entire table and was made from:

(2) RadioShack portable cassette recorders
(2) RadioShack Perf-Box VOX kits (more…)
