Just offhand, I think I'd use a relay to handle the rocket igniters. They are generally more robust in regard to overload. I'd also put a fuse or fast circuit breaker (or solid state current limiter) in series with the relay in case you short out the igniter leads. ______________________________ Reply Separator _________________________________ Subject: Re: HELP with an LED Driver Author: verhage@HUMEC.KSU.EDU at internet Date: 12/16/96 6:35 PM Not only to drive an LED segment, I'd like to hear suggestions for using a controller to ignite rocket ignitors. As I understand, I'll need at least an amp to do that.
