Step 1: Tools and Materials
Soldering, stripping cutting tools.
Hot glue gun
4 Super-bright LED's
Step 2: Plan
First I figured out the properties of the generator. By connecting the LED with and without series resistors I discovered the internal resistance of the generator was effective in limiting the current, so I did not use a series resistor. I also determined that the LEDs were better in parallel than series. A o-scope showed that the generator generated AC. That meant a couple of things, one is that reverse current might damage the LED's and the other that the LED was only on half the time. I could have used 4 diodes in a full wave bridge, but I decided instead to use 4 LEDs in parallel 2 connected in each polarity. This limits the reverse voltage and now 2 LEDs are on all the time. I also made a little jig to hold the LEDs while I soldered them.
