What i want to know is if anyone has or knows of any way, schematics or anything, to make somekind of wireless fireworks igniter. i already have the igniters(and they work awsome, just say something if you want the link), but what i need now is wireless transmitter and receiver to control a bunch of relays (12+ would be good). i know they sell some IR and radio controllers like this but i would really like to get a design or something. if anyone has any info no matter how minor please reply, it would be most heplful. Thanks.
