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
1x 2.2k resistor
4x 1000µF capacitors
1x SCC2433B-MSE Solarcell
1x RM1a motor
3x large paperclips
1x flashing LED
Print-outs of free-forming instructions

Note: The FLED version is easier, and takes a bit longer between movements. Please note that to bring this package to you at such a great price, we cannot offer the same 100% satisfaction guarantee as we do our full kits.
