Cheapo 12v battery (edit, I have a 12v, but 20v batteries could work), random electronics from China. Garage door opener relay kit isn't up to code for legit launches, but it works for the local field where my kids want to push the button, but don't like loud noises.
Was a bit small to wire everything in. If I had to do it again, I'd probably make it bigger. Ordered a keyed switch as well but I guess that boat got lost.
