mine dosent work. i think the cap is charging, but not discharging. checked with multimeter, hovers around 3v.

Suresh,
No, a FLED and an LED are not the same. A FLED stands for a “flashing LED”. It’s basically an LED with a chip that’s built in that causes it to flash. It has a higher turn-on voltage than a normal LED. RadioShack used to sell them in their stores in the US. I’m honestly not sure if a regular LED would work. You can always try.

I can see what you have made – but why did you make it? What purpose does it serve? How could I use it?

Because the FLED are photo sensitive they may have difficulty operating correctly in bright light, seen as you will most likely be using this engine in bright light, it is best if you cover then so they operate correctly

Hey Nick,

Hook the emitter leg of the 3904 to a negative capacitor lead and the emitter leg of the 3906 to a positive capacitor lead.

(When you hold a transistor with the flat side facing you and the leads pointing down, the emitter is the very first of the three wires — Emitter, Base, Collector.)

After that, the solar cell can go to any + or – lead on the caps, just make sure that + goes to + and – goes to -.

Where do the motor and capacitor attach?
