Operation is a game that lets you test your hand-eye coordination by removing a variety of ailment tokens from a cartoon patient without touching the metal sides of each slot. Since its release in 1965, there have been a lot of special editions created. These feature popular characters such as  Buzz Lightyear, R2D2 and Iron Man. The game's simple design makes it very versatile and easy to adapt.

In this instructable, I am going to show you how you can make your own Operation style game from scratch.

There are a wide variety of construction methods and materials that you could use to make this game. For example, you could vacuum form the game board or 3D print the ailment tokens. But for the sake of simplicity, I am going to illustrate the process using materials that are cheap and readily available to anyone. Feel free to make changes and substitutions. As long as the basic circuit is set up the same it should still work. This is a custom design project afterall.

Materials:
Printout of your character
4 sheets of cardboard (about 8.5 inches x 11 inches)
Thin sheet metal (about 8.5 inches x 11 inches)
2 feet of insulated copper wire
Tweezers
Heat shrink tubing
2 AAA battery holders
2 AAA batteries
3V buzzer (Radio Shack Part # 273-053)
Multipurpose glue
Double sided tape
13 small objects to serve as ailment tokens
1/16 inch thick sheet of plastic

Tools:
Soldering iron and solder
Tin snips (optional)
Sharp knife
Binder clamps
Fine tipped marker/Sharpie
Pencil
Ruler
Dremel rotary tool with cutting and grinding attachments
Drill and bit set
Needle or push pin

Source Tips:
The cardboard is easy to cut out of a large shipping box. For the sheet metal, I used a baking sheet that I found at dollar tree for $1. This yields about 13" x 9" of metal. The sheet of plastic can be salvaged from the housing of an old electronic device.

Could I use a layer of tin foil on top of the cardboard? Less sturdy but easier to do.

That would probably work. You can' solder to foil, but you could just tape the wires in place.
