Simple Boost Converter with Relay 

The way that you explain the basics of electronics and the circuit itself is awesome, you make things pretty easy to understand.

there are many tutorials about boost converter, but ..... You are the best in explaining it - loved your videos !!!!!

Very useful! Thanks to your previous video about boost conv. i had won a county physics competition, i won a 32GB U3 sd card, a Parker Vector pen and some goodies. I used a relay as a inductor, 4 aa bats as V source, a tact switch, a 1n4148 diode, a 470uF 27V cap and two 1M ohm resistors, because i had found that higher loads give out higher voltages, most likely because the cap discharges more slowely. Thanks for making those videos!

I still get excited seeing those nice brick brown tantalum capacitors. My favorite. Great video.

thats the video i have been looking for

this is a very useful video for teaching purposes

very good Chanel for learn Englishtronic for me. thanks.

Nice video

Actually I worked to this circuit last year because I tried using relay oscillator as a switch for boost converter

Very interesting for using a relay as an oscillator. By the way what might be the frequency of this oscillator?

please say nut again 🤣 nah just kidding m8 keep up the good work king :D

the electrical pencil or lighter high voltage relais prinzip , for 40 years it was a chrismas or birthday gift :) :) :) ,,, if this relais drive a mosfet with toroit coil , it works as a powerful up voltage charger , with a shunt or temperatue sensor and schmitt trigger , it finished loading automaticly

Nice!

Could this be used as a battery desulfator ? 🤔

Saudações LS Ludic Science. Muito bom. E simples. Mas, por que a alta tensão não danifica as pilhas??? Tudo de bom.

this is the best youtuber ever!!

Can you please make voltage doubler from relay and 2 capacitor

I made one that uses a 555 timer and a mosfet and a inductor out of a computer power supply, I can get just over 400 volts from a 9v battery! i might make a video of it.

how about using attiny 85 + potensio to change delay value high low high low high low?

Awesome. I wonder how long the relay would last flipping that quickly though. ☺

Can't you use the inductor inside the relay as the circuit inductor?

You should have tested it with a load at the ouput. But still it is a good demonstration of the circuit operation.

Absolutely awesome!! however, Joule Varas connection is simpler, and no additional power source is needed. runs on batteries alone.

I think I'm going to try a version of this to drive a flyback.

Where could I get a meter like the one you used to measure the inductance of the coil?

Professor - Is it possible to use this circut for a flyback driver?

What power it could gain? How long can such relay work?

What exactly is a boost converter used for?

That’s cool, relay oscillators are really cool, but highly innefiecent. Could you do another video on the circuit using mosfets? Also could you make a video using crystal oscillators?

Go big

Прикольный канал!лайк

And the amperage goes to 0.0001?

you could make a buck converter like that as well

That's useful but i think the output voltage is Ac

Now use it to drive the primary of a transformer
