The importance of the 2N2222A to civilization cannot be understated. Serving as a fundamental building block in electronics, it was pivotal in modern electronics. This humble transistor has indirectly shaped technology for the past 60 years. #TransistorLife #DatasheetDigest
@MakeAugusta I always thought a great book would be "101 Transistor Projects using only the 2N2222A"
@MakeAugusta I would say: 2N2222, BC238 and the NE555 (and maybe ua741) are complete references for successful general purpose designs
A darn fine and timeless component. Back in the mid 80s I used 2N2222s to make and modulate a Colpitts oscillator. I sized my tank circuit to for 90Mhz. By stretching or compressing the inductor I could tune any frequency in the FM band. With the use of a 99 cent Radio Shack condenser microphone, I ended up with a very low noise, sensitive listening device with clean modulation and a ~.3 mile line of sight range.
@MakeAugusta @DatasheetDigest I always thought the most versatile transistor was the BC548, but it can't reach vhf frequencies...
