Introduction: Yet Another Rechargable Light

About: father, son, brother

this is a circuit that incorporates a capacitor, resitor, diode and an bright white led and uses a Lego motor and connector to charge the 1 F capacitor.

Step 1: Gather Materials

First, gather the parts you will need:
A 22 Ohm resistor (r,r,b)
a diode, 1N4007 ( or whatever you have)
a bright white led
5.5V 1Farad capacitor
push button switch
protoboard, or whatever its called (used to prototype circutits)

Unfortunately I forgot to take photos of the individuals parts, except the capacitor.

Step 2: Cannabalize Your Mindstorm

cut off one end of the a lego connector and wire one side to the 1n4007 diode, connect the unconnected leg of the diode to the negative side of the capacitor, and the other side of lego connnecto to the positive side of the capacitor. The diode will prevent the capactor from dumping its charge back to the motor.

Step 3: The Resistor Is Connected to the ...

Now connect the resistor to the positive side (longest leg) of the bright white LED, attach the unconnected side of the resistor to the positive side of the capacitor.

Step 4: The Negative Side of the LED Is Connected to The...

Connect the negative side of the bright white LED to the pushbutton. Then connect the other side of the pushbutton to the negative side of the capacitor.

Step 5: Connect the Connector to the

Now connect the lego connector to the lego motor( I have a big tire connected to the motor that I will add photos of) and spin. Spinning in one direction allows the tire to spin effortlessly, spinning the opposite direction will be met with resistance. That is the direction you want to spin the motor so as to charge the capacitor.
