In this ible i'll show you how to build a funny and cool LED project.
I'll basically secure 6 blue LEDs to the spokes of the wheel.
The result will be fabulous! And it's also a useful project because these LEDs, while cycling, will make a perfect bright circle that will help car drivers to notice you in the dark.
P.S. I entered this project in contest! If you like it please vote for me :)
So..let's go to see materials and tools!!
Step 1: Materials and Tools
- heatshrink tubing
- 3x 100 ohm resistors
- ON/ON switch
- 9V battery snap connector
- 9V battery
- soldering iron
- cable ties
Step 2: LED and Resistors
As you can see in photo#1, we need to connect 3 couples of LEDs in parallel being careful to follow the right polarity.
I decided that 6 LEDs would have done enough light, and as I initially thought, the result is fantastic!
I suggest you to put 6/8 LEDs depending on the size of your wheel ;)
I wanted to make the result as clear as possible so I soldered two LEDs with a resistor, leaving the wires long as the wheel spokes (24cm) at the sides, and the double (48cm) in the middle. (this because the middle wire will connect two LEDs fixed on two different spokes, so it will have to go from one LED, down the spoke till the wheel hub and again up on the other spoke till the second LED)
Before attaching the LEDs to the spokes, I suggest you to check if all works correctly and if your LEDs are bright as they should be.
After you have soldered, tested and insulated all the three couples, you can go to the next step.
Step 3: Switch and Battery Snap Connector
In this step we will simply solder a switch to the 9V snap connector.
