A little bit of fun, a little bit of history, a little bit of knowledge and a little bit of hands on. Very nicely done. We are looking forward to more. Keep up the good work. It’s good to start to understand exactly what all those little thingies are doing inside our electronic devices.

Seems unnecessary, so I must be missing something…

At 7:31 you mention a phrase to remember the order of the leads of the transistor, but it is valid only for this particular transistor. It might be confusing.

Frenzy: There is already a video on the resistor, capacitor and diode I think, I’m pretty sure the one on the resistor covers Ohm’s law so you should check the archives.

thunderhammer: I think the 100k resistor is here to lower the sensitivity of the amplifier.

Without the 100K, simply bringing your hand close to the wire will cause the LED to flicker because of the 60Hz (or 50Hz) AC mains being picked up. In fact, even without AC mains interference, the LED may glow slightly due to current leaking from collector to base from the resistance of the plastic it’s molded in, or else from current sneaking through the transistor because it’s impossible to make something perfect.

Excellent infotainment!
