what is needed to build a electric trigger

[THEFITZ]

If i were to build a homemade electric trigger what would the parts be to build it

[Dayspring]

YOu gotta find some way to trip the sear or push the on/off, a microswitch or opto sensor, board & chip that you programmed, bunch of other stuff.

Unless you're an electrical engineer & mechanical engineer- leave it to the experts.

if im correct the electrician made one from scratch or near scratch maybe he supplied a guide or how to or what parts u need i suppose u could pm him and ask him
