Dang, well I see you got a solenoid of some sort to open up the valve in the air tank and release air, I figured that's how you were going to make the spider jump. I'll let a few more people take a shot at guessing before I ask, lol. I'm curious about this now.
yes.. to be fair I don't have the electronics mounted inside the box. I ordered a single channel remote control to trigger it. and I am waiting for a 120PSI safety relief valve too, so I don't put too much pressure inside it
