I'm going to throw in my 2 cents on this topic On the "no continuity thing" with the RfRemotech stuff, their receivers can only switch 10amps max. It will draw only as much as it needs and not more. Model rocketry has a fair few things you need to understand to get the most out of launching model rockets. Not wanting to hassle with a separate battery for the Arduino, but _cannot_ tolerate an uncommanded launch! This simplifies the problem a lot. Simply the model rocket launch controller works by delivering electricity to the igniter, which ignites and starts burning the rocket motor. This website contains material which is owned by or licensed to us. I wanted to make a Launch Controller for model rockets with a bit more power than the generic 6v Estes so i could launch rockets with multiple engines etc. The Arduino only needs to send TTL logic to the driver board, not power the coils. I2C seems easy. The receivers are 4 channel relay banks. We will promptly correct any information found to be incorrect. 4 0 obj Why not do continuity checks AT the pad, rather than running back and forth to the "away" controller to see if you fixed it?
