A couple of questions on the 2N2222 transistor

oric_dan:

They look right to me. The base is in the middle where I expect it and the plastic part would fit in the standard TO-18 triangular PCB layout without having to cross the legs.

I think the "round" part of the PN2222 body and the "curved" part of the 2N2222 pin
arrangement point in opposite directions, so if your pcb layout looks as follows, you're
up the creek [of course, I may be upside down over here],

The silkscreen may be misleading. All goes to reinforce the fact that you need to look at the data sheet.
