Great stuff yet again. This channel is now in my top 6. The others being (in no particular order) Colin Furze, Abom79, Cutting Edge Engineering, W2AEW and Applied Science. So, you are in very good company. Great work and keep it up.

[@electrarc240]

Wow, thank you very much!

[@drwhopoo6604]

best part of the video is the lightning to BNC adapter

[@electrarc240]

Haha, glad you also appreciate the finer things in life

[@u3b93]

You have the art of explaining fundamentals. Keep it up, wish you created much more content like that in the future.

[@electrarc240]

Thanks, that's the plan!

[@mdtanvirahmedsagor6146]

Your videos are great brother.

[@edic2619]

Great video. Cool audio amp.

[@TheOriginalEviltech]

Your videos are so good i tried subbing twice!

[@mattwillis3219]

Awesome description! Would love to see a fast photo diode looking at the output intensity, comparing the switching rise and fall to the output intensity.

Ur chanel is a gold mine keep it iam happy i came across your chanel

[@electrarc240]

Wow thank you so much!

@@electrarc240 ur electronics knowledge is great and sharing it with us is even better

I always wanted make some simple inductor testers myself, but I think I'm too lazy. But I have special DIY generator for testing saturation current, which my dad explain to me and it is great device. PWM controller with mosfet and potentiometer for PWM setting + power supply and couple of shunts for osciloscope :) And few years ago I made inductor meter based on op-amp generator. Recently I bought Uni-t LCR meter which make great job measuring caps in circuit without desoldering. Downside was price for me, but it saves lot of time in servicing electronics.

[@MyProjectBoxChannel]

I think most electronics enthusiasts draw a lazy Simplified version of a mosfet😂. I can never remember how to draw it properly😮‍💨

[@TheLightningStalker]

There is something to be said for having a nice stable voltage reference.

[@willusher3297]

Lightning to BNC? Can't say I have one of those in my collection. 🙂

[@leehewitt9559]

Good work. Just out of curiosity, do you work in electronics or is it just a hobby? You seem to have a professional background, university degree?

[@electrarc240]

I did it as a hobby for many years before studying it at university, which I was doing when I made this video. I am now on a year placement working on the Formula 1 hybrid system at Red Bull

@@electrarc240 excellent. Keep up the good work👌

[@Rollmops94]

8:07 Shouldn't the comparator inputs be swapped?

[@Rollmops94]

No wonder you couldn't get the hysteresis to work.

[@spiderspider1384]

Hey dude , do you have the circuit for THE SATURATOR circuit from the video 3:17

[@electrarc240]

Just a MOSFET, a freewheeling diode, and a shunt!

[@VEC7ORlt]

Rod Elliot from sound au has a more comprehensive one.

you guys have a discord or anything?

Not yet, think I should make one?

@@electrarc240 i have a lot of hobbies, i write ttrpg content, reverse engineering/hacking, programming, synthesizers and audio production.. but none of the discords im in talk about electronics fundamentals/experiments on this level. lately ive realized i needed to take a step back and work on circuitry/electronics fundamentals so your videos have helped

[@stevenbliss989]

If you put a cap on the output of the inductor to ground, you likely will get rid of all that lossy ringing.

[@stevenbliss989]

It may be gate ringing?

[@GinoDeCock]

Do you have a schematic that you want to share?

[@electrarc240]

This circuits pretty bad so no haha. The next current control video will hopefully show something a little more useful
