Thanks Misha. Have you got something about how to use the parachute deployment circuit that you have created here.Something with a few steps to explain its use.
My son and I started building water rockets a couple of years ago (with plenty of info taken from Airrocketcommander) and quickly came to the point where we needed a parachute to slow the decent, as we all our efforts where beginning to plow into the ground a Ludicrous speed.I have been trying to learn the art of arduino so that I could build just what you have here.Thanks in advance.
During the setting out, I just used the plastic base from the router to located the holes to eventually attach the router and the acrylic.
thanks very much

Hi There. Thought I would weight in with a little bit of background knowledge for you.I used to work in a materials (soils and aggregates) testing lab, and one of the things we used to test was concrete.We would be delivered concrete samples that were poured into specific molds on site at the same time as the concrete for whatever the project was. We would then store them for 28 days (here's the kicker) in a large, temperature controlled water bath to allow them to go off in the best possible environment for strength.Just saying.
