In any case, don't plan on building much other than a solar cell to
start. And keep things really simple and as safe as you can, as you
learn.

Of course, there's always the possibility of building point contact
transistors out of silicon in the comfort of your garage or kitchen. With a
flouride etchant to thin down a silicon wafer in the right spots and some indium
solder you could probably make a passable junction transistor.
