It has a small square graphic color display on the upper right and a slide switch to the right of it ... Note that there is something fishy going on with NPN transistors. An NPN transistor placed in ...

Abstract: Thin-film transistor (TFT) technology has demonstrated its effectiveness ... However, TFTs are typically unipolar in nature, and therefore, the realization of CMOS-like digital circuits is ...

Well, a 2N3904 NPN transistor worked in theory — until it blew and was replaced with one of the beefy 160V, 15A transistors that were salvaged from the original circuit. A trio of commonly ...

With your help I’ve mapped out the circuit, and taken control of the bulb. But there’s still a few mysteries in this little blinker. Join me after the break to see what I’ve done so far ...
