    My question is if always it has to be a finger or relay involved to press the switch, how transistors switch themselves on and off thousands times per minute?

    That was fun, I don't mind the podcast presentation, it's always good to have something to listen to while doing other things. I did get a few things: the battey tester II've wanted one for a while. The Picos, I have a few of the RPI boards but I like the smaller footprint for smaller projects and they are good for learning when you don't need a lot of pins. And the 10 mm LEDs, again something I've wanted for a while, I have some 8mm, but now I'll have more variety (way too many varieties now). A couple of things sit unchecked in my cart. I agree with the brass (metal) for cleaning soldering tips, I tried sponges when I first started (because all the experienced KZreadrs swore by them) and found them frustrating . Once I got a brass ball, I never looked back.

    If I PWM one of the PWM-inputs while keeping the Enable on both high, wouldn't that hard-brake the motor in the low-phase of the PWM (as both lower side FETs are on at that point), which would make for horrible efficiency?

    I am sitting here using those boards to make custom solar lights for the decks around our house and the first video that comes up in my list is your's and i didnt search or google the circuit or anything. haha. you are right about soldering. i learned from wiring guitars but i bought cheap chinese smd kits to learn how to repair electronics and cad up boards i etch at home. what's your preferred software for designing boards? i'm testing out one of my new laser diodes and tbh havent used a proper piece of software in well over a year and the ui for kicad and easyeda look different now. i no longer have custom libraries saved for common parts. i've used either flexible smd/tht protoboard (i forget the brand but they sell it everywhere) or fr4 and a dremel the last while haha.

    Great video. Looking at buying such a device for reflow. After seeing some others that used this but did no teardown I was unconvinced to buy it, but your teardown that shows the good and the warts and suggested fixes for the warts gives me a lot more confidence. Yes, it's certainly "built to a price" as you said, but that's not a bad thing -- IF we can make it safe. Thanks!

    What happens if you disconnect one of the output wires while the motor is running? If the chip burns, you would need external schottky diodes to VCC and GND on every output pin. Synchronous rectification won't be good enough in that scenario.
