U.K. Hello Lewis. Just found your channel, sorry I'm late on this video. There are dozens of LM317 videos but yours is the only one that adds a bit of 'thrutch with a power transistor. I think perhaps your 10Amps might be a bit high, sort of 'frying tonight'. I used cheap Chinese TIP35C's as the are easy to mount. 6 in parallel with balance resistors on a heat sink the size of a brick with 3 server fans howling gives 12A forever. I did test up to 20A but the 16A 36V transformer got hot. I have 2 of these and have driven both TIP35 banks from 1 LM317. Nearly burned the dining table. Nice video.
So if this transistors act like a current stabilize so even if you set up an output 5v 2a and your input 12v and it will take 2a too from the input. Is it considered a power lost as 12x2 =24w - ( 10w output )= 14w power lost inside the transistor . Is it a not good idea ? Or ..... This can consider a best way to drop a 7 volt from a buck converter lower to 5v with less lost power ? So it's it can consider a safe side for the output electronic since the buck converter have a lot of noise in the output and we take pure DC 5v ?
Your video would be more fantastic when you are reading the current with multimeter and displaying the readings so that people will see.

Very good 👍

Where did you hide the electrolytic?
What electrolytic? This operates from a DC power source. I may have used a small one for noise.
@@LewisLoflin I thought I saw an electrolytic in the circuit diagram but I couldn't see it in the circuit board.
