Who knew you could use the guts of a power transistor as a solar cell! Steven from RimStar even takes it a step further and chains five 2n3055 in a base to collector configuration to generate enough voltage to power a small calculator. Funny how some electronics form China are working fakes. The small calculator he got has a small solar cell in it already but once the case was cracked open it turned out that the calculator was simply powered by a small coin cell battery. I wonder if the solar cell was a fake or they were just too lazy to hook it up.
