For all you electronics fans. Here is a set of 3 Rocket Altimeters. All of these have been tested in a vacuum chamber and they all appear to work as advertised. First is a Transolve p6k. Records peak altitude and fires a main and secondary charge at programmable altitudes. See the Transove website for additional info.

Next is a PerfectFlite Microalt recording altimeter. Records altitude and will fire ejection charges. See the PerfectFlite website for all information.

Last is a home made altimeter that should be equal in performance to a Missile Works RRC2. It uses the missile works IC and is functionally equivalent. Records peak altitude and will fire a main and secondary charge a programmable altiudes.

As I said I have tested all of these in a chamber and they do work but use at your own risk. Perfect for electronics types who want to play.

$80 shipped for all three
