Intro: LED Hotwheels
Heres how to turn your favorite hotwheels car into an awesome light-up display or night light.
To take apart the car, you must first turn the car over and drill out the mounting rivets that hold the car together.
Next we use masking tape to cover the car up so you dont scratch it all up.
For this step you prep the car for the holes that will be drilled out for the head and tail lights.
Now drill your holes.
Next we add some leds to the car. I used some five minute epoxy to glue the leds in place.
The circuit is pretty simple series / parallel combination. The parts needed are::
- 2 red leds (tail lights)... i used red 3mm
- 2 white leds (head lights). . .i used some small blue smd that i had
- 1 150 ohm resistor 1/2 watt
- 1 9 volt battery
- some wire
Here you wire it up using this schematic. Then modify the windshield and seats of the car so that the resistor and leds fit when they are assembled.
final assembly and power test. Heres a few others that i did for some friends.. .
