Do you want to build the Make Volume 06 SolarRoller Project? This provides all the electronic parts specified to build the SolarRoller.

Note: You can try using the pinch roller from the cassette mechanism, but you may want to find a large pinch roller salvaged from a dead VCR or similar tape-transfer mechanism. It's all part of the challenge of building from junk

Included Parts:
1x 37 x 33mm Monocrystalline Solar Cell
1x 2.0V (C) Voltage Trigger
1x 2N3904 NPN Transistor
1x 2N3906 PNP Transistor
1x 2.2K Resistor
1x Metal Cassette Mechanism #2
1x 0.35F Double Layer Capacitor

Please note: This is a parts bundle, and to give you additional savings it does not come with documentation, free technical support or a 100% satisfaction guarantee. It's just a collection of parts! It's just a collection of parts! While the project instructions were published in MAKE Magazine or from MAKE issue 6, you can also get it online here.
