Here's my car that has an electronic trigger. Not the lightest design, but still fun to build and watch.

The car basically has a simple spring switch at the front of the car. I use the normally closed terminals of the switch. So, when the starting gate is down, the switch is pressed and the circuit is open. When the starting gate opens the switch becomes unpressed and the circuit closes.whodathunkit wrote: blue smoke,
Cool looking co2 car!
How did you build the electronic trigger to fire off the co2 bottles if I may ask ?
