Fig. 2 displays the circuit diagram of the standalone shock and vibration sensor device. It is built around transistor 2N2222 (T1), two electrolytic capacitors: one of 10μF, 16V rating (C1) and the ...

The new type of transistor, known as the "cryo-CMOS transistor," is optimized to operate at temperatures under 1 K and emit near-zero heat. A new type of transistor can dissipate almost zero heat ...

[Rupert]’s IC is just three parts, a 2n2222 transistor, a 220Ω resistor and an IR LED. With a good bit of deadbug soldering, these three parts were melded into something that resembled ...

To the circuit you’ll now add the MIDI circuit. For this you’ll need the 2N2222 transistor. Hold the transistor by the legs with the tab facing you, the pinout for the transistor is ...
