JCM Inventures Chloroplast Solar Engine Kit

The Chloroplast Solar Engine is an elegant and efficient solar engine capable of driving large toy motors with bursts of energy. It is the heart of the Solarly and Sunflower Power Plant.

The kit contains the following: an MC34164 P-3 Voltage Trigger, an MPSA12 Darlington Transistor, a Motor, a 2200 uF Capacitor, a Sunceram Solar Cell, 2 x 100K Resistors, a Printed Circuit Board and 6 inches of wire.

Equipment required for assembly: soldering iron, long nose pliers, wire cutters, wire strippers.

Approximate assembly time: 1-2 hours.

* Requires Basic Soldering Skills.

Solarbotics Symet 1381 Solarengine Kit

These aren't kits, as much as they are an inexpensive bag of components so you can build yourself a Symet.

A set of basic instructions are included that show you how to free-form a 1381-based Solarengine, and how to assemble the mechanics.

The Symet parts bundle includes:

- 3904 & 3906 transistor
- 2.2k resistor
- 4 x 1000uF capacitors
- SC2422 Solarcell
- RM-1 Motor
- 3 large paperclips
- 1381J trigger & diode
- Print-outs of free-forming instructions

Note: The 1381 is harder to build then the FLED Symet, but is also more power-efficient.
