Got some time on your hands over this Holiday vacation? Now that you have some new power tools, what about making a vehicle out of some of your old power tools? You can enter the Power Tool Drag Races in San Francisco or just post your project on one of the innovative websites like Hackedgadgets.com or Instructables.com.
Alan Parakh from Hacked Gadgets created a radio controlled vehicle made out of cordless screwdrivers. Check this out!
“This is a radio-controlled vehicle made from two cheap, cordless power tools with wheels attached. The electrical control part consists only of an old R/C controller, two servos, and 4 microswitches. Since I had most parts already in my part bins, it cost me about 20$ to build.
When I first saw cheap cordless screwdrivers, I started to think about (mis)using them for a purpose like this. A self-contained gearmotor with rechargeable power supply with a socket for attaching anything you wanted seemed perfect for a small vehicle or robot base. Not to mention far cheaper and easier than rolling my own. So I decided to make an R/C car out of two screwdrivers to see how workable it would be. And while I was at it, I resolved NOT to use any fancy motor driver electronics or anything. It can drive and steer without electronic drive motor control - it uses switches only. It worked great.”
