Looking to dip my toes in to some remote firing, and thought i'd try to step it up a bit from a simple nail board, but not by much more.
No resistors or diodes, just a simple little system, but I want to make sure my little theory would work before going any further.
There are a few Ethernet firing systems out there, so I thought I would dumb those down a bit and make a cheap one. Using 24AWG UTP 8Wire Cat6 under 300ft should be fine with a 24V/3000mA battery.
Using the eight wires, I would make one a ground and run that to a selector to make one out of the four rails active at a time. Each of the seven push buttons would then be wired to one of the same color across all four rails. So button one would be all purple, and when pressing it, it would simply try to throw current down all four rails on the purple wire, but with the selector only on rail one, only channel one on rail one would fire as that is a complete circuit.
Make sense? It's a bit of a mess, but hopefully it came out sort of clear. I'm pretty sure I can get away with this without any sort of resistors or diodes, so this is super simple. My one concern is that can anyone see a chance of a missfire with this? With a common ground there shouldnt be any stray current going anywhere else, but idk. My EE is a bit rusty.
Also, I am curious if anyone knows the answer to this but, how do some of these pro ethernet systems get 12 channels on one rail with only eight wires?
Thanks, dont be too rough on me.
