for some reason i didn't get the emails telling me people had replied to this... don't worry about this now, change of design for other reasons has rendered this obsolete, but, just to make it a bit clearer, the fuse isn't a regular electronics fuse, but actually an "electric match" used for firing pyro's... I need to build a circuit whereby i can "arm" the channel (close the switch to that channel) but not actually fire it.... using the 3055's when i had enough power to arm the channel there was enough power to blow the pyro, with only one pyro on the channel the fire current is approx 300mA, but it's going to be much greater with 20+ pyro's on each channel... tbh i don't think ive made this any clearer, but hey, im using relays now as they do what i need of them...
Anyone have any ideas on how to use CANBus, or more to the point if i use two MCP2515's to send data between 2 locations, ie tx on one connected to rx on the other, do I need transceivers? I'm going to put another thread up in a sec on this subject...
Cheers
