Introduction: A Simple Circuit Game

About: Developing projects for HowToons @ Squid Labs.

Make a neat little game using a simple circuit.

Step 1: Gather Materials

For this project you will need some wire, electrical tape, a 9 volt battery, and a light or buzzer. I chose to use an LED light, but a buzzer would probably work better. You will also need wire strippers.

Step 2: Strip the Wires

Cut a few pieces of wire. The lengths need to be as follows: 4", 14", and 16". Strip the ends of the 4" piece. On the 14" piece, strip one end normally and strip the other end about twice as much, about an inch of wire. On the 16" piece of wire, leave about 6" of insulation on the end, and strip the rest of the wire. Strip the other end of the wire as you normally would.

Next, you will be bending the wires. On the 14" piece, make a loop in the end that is stripped more. Then on the 16" piece, loop the part that is still insulated. With the rest of the wire, make a zig-zag design. Check the picture below to see what it should look like.

Step 3: Connect All the Parts

Take the LED (or buzzer) and attach the smallest wire to one side and the 14" wire to the other side. Then take the small wire and attach the other end to a pole on the battery. Then take the longest wire, and attach the end to the other pole on the battery. Refer to the picture to see how to attach. All connections should be made with electrical tape.

Note: If you are using an LED or other polarity sensative device, make sure you have all the poles correct for it to work. By switching the wires around on the battery, you can check to see if it is correct.

Step 4: Play!

If you haven't already guessed, the point of the game is to move the loop around the bended wire. Depending on how your bends are and how big the loop is, it can be pretty tricky. This game will keep kids entertained for a while, and is actually pretty fun.

Awww no resistor! That makes pain : S Okay maybe not :D

well I will have my own instructable relating this one. LOL !!! AN IMPROVED VERSION STAY TUNED

Made one of these when I was younger (I used a buzzer), but included a hidden switch - and cheated.

why no resistor? wont a 9V batteryfry an LED with out a resistor?

well, that is the case if it is burning constantly. in this scenario, the light only lights up for a split second, or at least that is the point. it is true though, the 9 volts will make the LED die much faster than normal.

I had a short circuit with a different circuit I made, it fried my High power LED on a 9v battery in about 3 seconds. Might help if you add a resistor to this circuit...

I thought so too but it appears that his LED is lit (of course theres no proof that it blew right after the picture was taken :P )

9V seems like a lot to be putting through the LED, they're pretty forgiving and its only a momentary voltage but maybe adding a buzzer or a resistor to lengthen the lifetime of the game would be good.

i agree, a 2.2k resistor works great with my experiments.

How does it work? I need to know for my school project.

from my understanding, the circuit is incomplete and when you touch it with the part when you hold it it completes the circuit the LED lights up

OH MY GOD! i made on when i was 11. i made it with a support (the thing to hold cloth on) and a ring. it was all glued on a wood pieces. it was for a school project, and i got the best note ! 21/20! (i got a bonus becose its was nicely holding on a wood plank!)
