In this instructable, I am going to show you how you can make your own Operation style game from scratch.
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.
Step 1: Materials
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.
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
Heat shrink tubing
2 AAA battery holders
2 AAA batteries
3V buzzer (Radio Shack Part # 273-053)
Double sided tape
13 small objects to serve as ailment tokens
1/16 inch thick sheet of plastic
Soldering iron and solder
Tin snips (optional)
Fine tipped marker/Sharpie
Dremel rotary tool with cutting and grinding attachments
Drill and bit set
Needle or push pin
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.
