G-switch timer

ElectronicsPosted by Morim Sun, March 09, 2008 20:15:01
This is a home built G-switch timer.
The G-switch is an ordinary microswitch with a M4 screw epoxied onto the leveler. By changeing the number of nuts, the trigger g-force can be set. Now I'll think its about 6G. After activating the switch, the timer will count to down to a pre set time, aprox 5-25sek before the igniter is lit. The current is on for .5s. when activated by g-switch a beeper will set of, and is active until battery is deattached.

The circuit has not yet been tested... :-)
