Congratulations to Blake on graduating high school; onto the next chapter of life. Green is good for "ON". Sometimes, the alligator clip holder is faster and easier. Turtle's may attack, be careful. Good build Paul, thanks for the video. ☮
That's what kids need. 4th grade we had some electronics thing with a lightbulb and completing a circuit. Always left a big impression on me. Had an elenco snap kit growing up. Always seen old school erector sets but never had any. Stuff my Dad resold.
Wait… there must be something wrong, turning the pot does not modify the output voltage at all…I think that the ADJ pin should be connected to the the wiper pin of the pot, and the feedback from R1 connected to ADJ. I might be wrong though 😅
Looks like you made a boo-boo with the adjustment, as illustrated by 5 full turns of the pot and only 10 mV change in output voltage. You should use the pot as a rheostat (i.e. connect lower side of R1 to adjust pin and one side of the rheostat, the other side of the rheostat goes to ground). Right now you basically have a third variable resistor between the voltage divider and the adjust pin.
Well I tried that setup out myself, and it does actually work. So there's something else funny business going on if there's no response to pot tweakage. Doesn't change the fact that it's wired strangely, though.
Another nice addition to the STEM board collection. Congratulations on Blake's graduation. Tip for the helping hands. Put two layers of shrink wrap tubing over the jaws. It will grip the PCB better.
If you change your 1k resistor (R1) to a 1k5, you will get a vout range from 1.25 - 9.58 volts. With the 1k, Vout is trying to regulate to 13.75v maximum, but can not because of the 12v input.
PAUL, Can you make a video lesson about how to make a power supply that can take any AC outlet AC voltage which its called "Universal voltage" because the power supply can detect the AC voltage and when step it up or down but you can explain in the video lesson how it does this because its considered a SMART power supply

I think it was. It wasn't fully visible. Around 3:20

Love the video. I wish there had been videos like this when I was at school
17:32 I *was* entertained. Thanks for the video.

Hear ya on the pollen. Am in Columbus. BTW love your channel!
Thanks neighbor
I am looking for a circuit diagram to receive a 27.185 Mhz signal.

So Paul, what is Blake interested in studying at college?
Physics
If I'm not being too nosy, of course.
