Did you know that inside every transistor is a little man whose job it is to watch the incoming base current and adjust the collector-emitter impedance to match the datasheet? Its true! And now you can celebrate the hard-working guy with this fabulous Transistor Man tee shirt.
The front of the shirt has the now legendary Transistor Man diagram from Horowitz & Hill's "The Art of Electronics". Not only did we get a blessing to make these from Cambridge Press, we even got a scan of the original artwork transparency from Professor Horowitz! These are without a doubt, the coolest NPN shirts we've ever seen.
Due to popular demand, we are now offering this shirt in a men's 4XL size! The 4XL shirts are 100% cotton, so they're super-comfy and very breathable!
