The 1381 solar engine kit stores electrical power from the sun. When enough power is stored the circuit dumps the stored electrical power through circuit load, in this case a motor. This kit may also be used with BEAM and Solarbotic style robots. High efficiency 1381 Solar Engine. Basic instructions included on a 1381-based Solar engine, The parts bundle includes:

* 3904
* 2N5060 SCR
* (4) 1000F capacitors (or one 4700 uF capacitor)
* SC-01 Solar cell
* DC Solar Motor
* 1381 trigger
