These aren't kits, as much as they are an inexpensive bag of components so you can build yourself a Symet along the lines of the PMK Trimet.
Basic instructions included on how to free-form (solder without using a circuit board) a Flashing-LED Solarengine, and how to assemble the mechanics.
The Symet parts bundle includes:
- 3904 & 3906 transistors
- 2.2k resistor
- 4x 1000µF capacitors
- SCC2433B-MSE Solarcell
- RM1a Motor
- 3 large paperclips
- Flashing LED
- Print-out of the free-forming instructions
