Do Not Push Box

So this came about as a thought of “who can resist pushing a button labeled ”Do not push?"" Thought about what I had laying around in the Lair and decided on this. You will need a 12v source, I chose 18650 batteries, a momentary switch, available on Amazon, power supply if you decide to pass on the battery option and a heap car horn, again Amazon or if you have one lying around. Basic soldering skills are needed.
