Testing circuits I found on the Internet: Inverter! It does work, BUT...

Websites which were shown during the video:

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!

We want a "Random circuit I found on Internet" series. 🙌

[Asu]

Me: _"Mum, can we have a real sinusoidal waveform?"_
Mum: _"We have sinusoidal waveform at home"_
*Sinusoidal waveform at home: **5:00*

This new series is something I would definitely watch. As people will miss out a lot of things whenever they see a circuit on the internet.

"let's see that sinewave..."
That part made laugh too hard I nearly choked

[xzerr]

Building a random device from the internet - sounds like a great topic for videos, hope this will ignite and not burn )

[RaduTek]

4:52 That complete silence made the moment so good.

[paradox]

The Title of your new format already gave me the chills..

[mo]

"but you're not reasonable, and want to save money" lmao i love this guy

[ToniPlays_]

I have watched the video halfway, this is gonna be a good one. We need more of these.

[RAM_e-Solutions]

I really appreciate this kind of video where you test circuit from internet. Maybe you can also do some circuits from forums!

[proxyhx]

Finally a new video, our beloved Great Scott has returned!

[dennisbengel]

Now we need a circuit of an inverter that does work and creates a perfect sinusodial waveform! :)

[iqtutorial]

I would love to see more videos on this series 🙂 especially some of those simple circuits found on internet such as descrete opamps etc...

[ryanf]

Absolutely love the idea of this video series!

[aeleequis]

This video series could be great. We could learn a lot from these

[cezarcatalin]

There are always 3 obligatory steps when designing new circuits:
- simulate them
- build them
- measure them in real life

[Optimuseq]

Maybe you can do the whole series of testing random internet circuits?

[sahasananth]

Do more "Testing circuits I found on the internet" this was really fun. Also can you ike me to the pens that you use?

[starsistor]

Very interesting, could you check some projects related to "Arduino MPPT solar charge controller"

[serignebah]

It's like it is a race on who plays the video first
