More info at: facebook.com Since I wasn't able to buy an altimeter yet, I decided to build a simple electronic delay timer. The video demonstrates how it works in principle. For use in a model rocket, just replace the LED with a low current igniter. If you need to use a high current igniter, just use 2,3, (or as many as you can), 9V batteries, in parallel.
