Spin Art Machine





Introduction: Spin Art Machine

I recently found an old Knex pinball kit that didn't work anymore, so I took it apart, hoping I could find stuff for arduino. During the "dissection" :) I found most of the pieces used for this, a 4 digit 7 segment display, and a motor box that works the same way as any other knex motor. I connected the center piece of the board and connected it to a motor, as well as some pvc pipe and a battery box from a remote control. Have fun!

Step 1: What You Need...

1. Knex electronic arcade.........$20 to $40 on ebay
2. PVC Pipe...........three "3 sided parts" and about 24 in. 3/4 and {1 inch (optional)}
3. Soldering iron
4. Hot glue gun
5. Battery pack..................I used one from a remote control, which was disconnected
6. 2 wires, about 6 in.
7. Drill
8. Paper
9. Paint and brush
10. Tape

Step 2: Getting the Pieces

Open up the center peice (the one that rotates in the middle), there should be a motor with a rubber-like band connected to the center. Take out the motor (you don't need the plastic around it) and don't take off the rings. Now, unscrew the large middle piece and take it out. It should look something like the picture above. Hot glue the piece you unscrewed to the bottom, and then hot glue the motor to the whole.

Step 3: PVC

On one 2 in. piece of pvc, drill a whole as close to the center as possible, making sure you don't drill all the way through. Then connect the rest in the fashion in the picture. It should look like an H, however with a stick in the middle. At the top of the "stick" should be the drilled pvc.

Step 4: Connecting

Now......solder the wires to the motor, place the wires through the hole in the pvc, and hot glue the motor in it. Glue the battery pack to the pvc close to the motor, and solder the other ends of the wires to it. If you place the battery in the battery pack, the current should flow, and the "centerpiece" should spin.

Step 5: Art Time!

Now to paint! Cut a circle in the paper as big as the centerpiece, and tape it. Insert the battery, and make your masterpiece!

Step 6: Your Done!

    Is there any way to make a splash guard for this?


    You could make it VERY simple....just putting a cardboard box around it....otherwise you could glue something to the pvc under it, creating a barrier around the object spinning. But really...it depends on the paint you use...the thicker, the less it creates the "spin" effect. The thinner, the more it flies-but it creates more of the effect.

    As for spin painting, you could also use glitter glue for the painting material, as well as paint.


    I would find that easier, actually (so the paint doesn't fly off). Im not sure, however, if it would stick too much and it wouldn't have the "spin" effect.

    A hard drive with a bigger disk on top of the platter, hooked up to power works extremely well.

    Old power supply, or connect the wires to the right voltages according to color. I just leave the whole hard drive intact, with a bigger circle glued to the platter.

    you're welcome. If you want, I think I can take a picture of everything. I can probably even figure out a wiring diagram for making one that just uses a wall wart. If I remember correctly, you have to hook up the entire hard drive to 5 and 12 volts. Not sure how you would use just a motor. I can't remember which colors are which voltages, but if you google it, you should be able to figure it out. If you just use an old computer power supply, that will work much better. you just have to hook up a switch to the power on pins on one of the connectors. If you wait, later this month I'll be making an instructable for a REALLY nice setup, that is fairly ceap. Wow that was a lot to type on a tiny 3DS keyboard. :)
