The SolarSpeeder 2 Kit is a very quick Solaroller that can cover 3 meters (10 feet) in under 40 seconds in direct sunlight.
This new version of the Photopopper is still a solar-powered, light-seeking, obstacle-avoiding robot, but now with update electronics & gold trim that make it twice as fast!
These aren't kits, as much as they are an inexpensive bag of components so you can build yourself a Symet.
This epoxy-encapsulated monocrystalline solar cell generates a nominal 4.5V / 18mA (sunlight) from a 24x33mm package. And has an integrated solarengine circuit board!
This epoxy-encapsulated monocrystalline solar cell offers 6.7V and 20mA in a 37x33mm package. Now updated with the Miller Engine circuit!
This big brother of the SCC3733 is also an epoxy-encapsulated monocrystalline solar cell, but this one offers 8 volts and 44mA in a 37 x 66mm package!
