This instructable is about how to make hand spinner with glowing LED lights! All you need to make a spinner:
- 3-layer plywood
- Bearing (from skateboard, roller...)
- LEDs
- 100 Ohm resistors
- Mini switch
- CR battery
- Wires
- Sinkers
- Some instruments
Also you can watch a video with full process of assembling.
Step 1: Bearing
Take a bearing: skateboard, longboard, or roller-skates.
The bearing has grease, it doesn't let bearing spin fast and long time, so use gasoline to clean bearing.
Step 2: Body of Spinner
Make the spinner's body of 2 pieces of 3-layer plywood (rectangular 30x100 mm).
Bearing has 22mm outer diameter, use flat wood or cone drill bit to make a hole.
Then fix both halves by screws and process with sandpaper to create a smooth shape.
Step 3: Electronics
100 Ohm resistor is for RED and YELLOW LEDs, GREEN LED is without resistor! Watch a scheme.
Step 4: Grooves and Holes
We to need drill 3 holes almost through body for mounting LEDs.
And make some grooves for switch, resistors and wires. Also make a big round groove for battery.
Step 5: Wiring
Use soldering iron to connect all components
Step 6: Assembling
Push bearing inside both parts of body.
Then make holes and push sinkers inside, it is for long time spinning (50 seconds for me).
Step 7: Final
THE END
