This game returned to my brain when I wanted to teach my 3 year old kid about colors. This is a very crude form of the original game. But it works.
Step 1: Parts
To make one like this you will require
Card stock paper
Cutting blade/punch (my kid lost my punch so I resorted to cutting blade)
Aluminum foil (the one used to wrap food is used here
Batteries, led, wire (i used one from some old toy)
Step 2: Make the Board
Take the ruler and pencil and divide the card stock in half. Distribute both sides into equal parts. This will depend on the size of your card.
Step 3: Drawing
Draw colors on both sides. Make sure everything exists on both sides. You can increase the complexity by increasing the randomness.
Also you can use stickers of animals and names or any other idea you can come up with. Sky is the limit here.
Cut holes for the terminals on each block. I did it the hard way of cutting. You can use hole punch if you like.
Step 4: Conductors
Take the kitchen foil and cut it into strips. Take scotch tape and cover one. And stick to the holes which connect. Scotch take keeps the foils from touching. Do the same for all the holes.
Step 5: Electronics
Take 2 batteries and an led and connect them in series. and bring out 2 terminals. These will be the leads for the game. Here you can see my hacking a pretty simple toy from my son's toy box. Test the terminals to check the circuit works.
Step 6: Done
You are done. Now place the terminal on the left to one of the colors. The light will only blink if the related option is selected on the right.
Step 7: Other Ideas
Here are some other ideas you can use to make your cards. These are take from the internet.
