 · Circuit Operation: The 220-240V AC mains supply is down-converted to 9V AC by transformer T1. The transformer output is rectified by BR1(which is a rectifier circuit consists of a diode) and the positive DC supply is directly connected to the charger’s output contact, while the negative terminal is connected through current limiting resistor R2.

So this time I made my circuit board finished with all parts, tested it, and as a final step cutted by a rotary tool. Waaay simpler, believe me! :) I used a TO-220 house MOSFET because I didn't have smaller one at the moment. As the switching transistor does not get hot at all a TO-92 package would work well.

A crystal does not oscillate on its own. You don't simply apply power and get oscillations out. Think of a crystal as a very accurate and sharp frequency filter. You put it in the feedback path of a amplifier in the right way, and it causes the circuit to oscillate at the crystal's resonant frequency. It's the circuit that causes the oscillations.

I'm pretty sure my parents wouldn't let me set up a circuit board barbeque to salvage electronic parts with. And from what I can find out about a solder pot big enough for a circuit board, I'm pretty sure that's too dangerous and expensive for a beginner like me. I would much rather stick with how my uncle taught me to do it.
