    I built a similar one recently, however used 12 turns of 18AWG wire, as I wanted to have a current controlled switch. Old reed relay from a dead burglar alarm sensor was the donor for reed and former, and it now lives in the car, where it monitors the current flow to the trailer light relay block, so that I can easily see, using one LED if the lights on the trailer are functional, as it will operate if the 21W lamp bulbs are on, but not for the 5W side markers. Thus can see at least one brake light is connected, and the turn signals are working. Yes you buy the trailer module and wire it in, but this one was made entirely of old salvaged relays, and a salvaged industrial logic plug in unit, with wires from old ATX power supplies for the sense wires from existing car lights, and then more to provide the outputs. 4 relays, and 10 wires to connect, with a long one fed through the existing loom to the battery, where it is fused with a 15A fuse. Fault green salvaged LED wil lnot light, as it is fed fron the current sense relay and at the front of the car. Reed relays are current or magnetism driven, you can use a few turns of high current, or hundreds to thousands of turns of low current, though if you want to have it operate off say 5V at 1mA you will need a lot of copper wire, as you need ot get the right number of turns on, and keep resistance low enough to operate off 5V.

    Btw. your videos are what made me repair my vintage Tesla car radio and cassette player. I would not be confident to do it, but when I see your videos, it gives me confidence that even an absolute amateur without any formal training in electronics can do it. It was a success, I replaced the C319 condenser by botching in two other condensers in parallel, fixing the problem. They were of same age, type and together gave the correct capacity. I used logical reasoning to determine where in the circuit the issue most likely is and limited my search to a couple of condensers as they were the main suspects. I was lucky to be able to use the other channel as reference when working, because with these vintage components, measured values tend to drift.

    Might be ugly but it's still a nice experience in making your own parts. Before I started watching, I expected building a relay with a moving armature from the grounds up - but using a reed switch makes things a lot simpler. Nice video :)

    I also come from the old school of fix it before replace it. Example is my neighbor came by to see what I was up to working in my garage and he was amazed I had my small trucks alternator torn apart on the bench and was replacing the bearings and brush assembly along with new internal voltage regulator. The old unit was constantly fluctuating from 12.8 to 14.8 v and causing all the lights to pulse up and down. I told him all the parts were only 20% the cost of a new unit and takes about a hour to do the entire job. Saved $160.00, I call that a win...

    yep especially if you want to make an alternator that produces over 200 -350+amps ( for a car/boat stereo/inverter)and not have to spend $800.-$1000+ for one.(thats even if you can find one for your motor with thr amps you want/need). ).

    Have you seen any of my passive crossovers for "hifi" speakers? I also wound the coils and sometimes I had to solder two pieces of wire, because I did not have one that would be long enough. Especially for beefy thick coils for the woofer driver circuit. Of course I do not use any circuit boards and just botch all components to the rear wall of the speaker cabinet, connect all the wires "in the air", so it resembles a "birds nest". On first, second and third look, it looks just like a tangled mess of wires sticking out of seemingly randomly fixed components inside the back of the cabinet. I fix them using hot glue as well as plastic zip ties connected to metal bars that are fixed by screws. I place the coils always 90° offset if possible, to avoid any interference and make sure that there is no iron nearby that would affect them, unless it is an iron core coil (I cut up and old washing machine motor to get two iron cores and wound wire from old transformers to make the coils. They had the correct impedance and DC resistance was even better than I expected (by 0,2 Ohms). I could not care less about how the whole crossover looks, as long as it works and is hidden inside the cabinet. I am pretty confident it will keep on working for decades to come, or unless the electrolytic condensers dry out. Due to cost reasons I could not use only film condensers, as their price rises quickly to unacceptable levels as their capacity increases. And they tend to get physically large too.

    3:32.. It would be really cool to see you use a white stripe on the drill bit chuck to have a sensor on some sort of like Arduino board calculating the amount of turns for you as the drill Chuck spins. Just have the white stripe pass a tachometer type sensor and count the revolutions it makes for you on a computer screen or something.
