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 1381-based 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 1381C trigger
diode
Print-out of the free-forming instructions

Note: The 1381 version is a bit harder to build, but more power-efficient.. 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.
