In this episode of “Testing circuits I found on the Internet”, I will be having a look at a popular inverter schematic I found on google images. The design uses an astable multivibrator in order to pull current alternately through a transformer and thus create a high AC voltage on its output side. A lot of DIY inverters use this functional principle. That is why I will build up the schematic, properly test the circuit and show you what problems it comes with that you can more or less easily fix. Let’s get started!

Can you suggest a simple circuit for solar light around 25w
I like this series
"but you're not reasonable, and want to save money" lmao i love this guy
I don't know as much about electronics as you do, but when we both read "astable multi vibrator produces a near sinusoidal waveform" I must admit I laughed.
Suggestion:
Joule thief circuits. For some reason I can never get smd/smt versions to work.
The classic one where you just tie everything into a little ball seems to work, but never the nice looking, super tiny smd/smt ones

This series is going to be fun!
Tried this circuit before
But the transistor burned my hand
good series
Try this 😀

Waiting for the "Build your own Pi" video and hoping that it's the pi 4.
As usual, excellent job ! Now question is, did you contact the web site to make them remove this dangerous circuit ?
This would be a great series to continue!
What software do you use for doing the schematic at 2.25?…….Thx
Die Serie ist geil, mehr davon
I've had a person argue with me that a RaspberryPi 240Vac relay add-on card he was demonstrating did not need an insulator sheet because there were no mains voltages present that could damage the Pi. The mains relays were through hole parts with exposed 240Vac pins.
12V -> 220V -> 5V -> 4.2V. It is crazy, this world is crazy. All this unification via USB, created from mains, no matter what.
Dude, all I hear from you is all the gasp between sentences. It's really distracting, there's a program called Audacity. I think it would be rather easy for you to remove all your gasps using that.
Make the simplest arduino nano SPWM inverter with optocoupler voltage feedback stabilization and from a rewinded MOT transformer (discard the HV winding, and rewind a primary center tap). How much power can it deliver at the output?
10:48 when cheap becomes expensive.

I think "i found on internet" will be good series to watch 🙂
For 40 dollars you can buy a proper 12V DC to 230V AC inverter. Most od electronic gadgets run internally on DC, so a buck/boost converter is more suitable way to power them up.
Stil for 40$ you cannot get or build fully sinusoidalnego inverter, so you cannot use it with AC motors.
But you can invest 40$ in educational electronic kit for you or tour children, so they can earń for a proper inverter and other cool stuff in the future.
That's a really cool video concept!
i am curius how it fried the phone and not the charger
Yay a new series!
Noice series
This is what we novice diy noobs need
Thank you very much
Thanks Man!!!
