The board game "Operation" is based on a very simple circuit, so you can build your own and customize it really easily!
Step 1: Intro and Materials
I first made this game when I was around 11 or 12, when I was on some rant about how the original Operation dude didn't wear any underpants. I told my mom she shouldn't let my younger brother play the game because it was inappropriate (I didn't actually believe this, though, I just liked arguing about things back then). So...I made my own (with boxers drawn on) and called it "Disease Remover". it's a very simple game to make, and it would make a really funny gift or practice for people who want to learn more about electronics.
Wire and wire strippers
2 AA Batteries and a holder
A small bit of spare cardboard
Step 2: Yep, that's all it is: The Circuit
There is one loop in this circuit, and it makes a complete circuit when your hand starts to get shaky and you let the tweezers touch the metal sides.
There isn't much to explain on this step; just make sure you connect everything with the right polarity as shown in the diagram.
There is gonna be a whole lot of wire hanging off of the negative end of the LED. This wire will make loops around the holes in your board, acting as the "metal sides" like on the real gameboard. Yes, this means you have to do a lot of wire stripping :c)
