Hi, I don't know much about electronics but I need a dc-dc voltage booster and ordering one online is not an option. This is the easiest I could find on YouTube but I have some doubts if its going to work. Can someone please confirm it for me? Thanks in advance.

 

It's legit in that its a simple unregulated boost converter but whether it'll work for your needs its unknown. Chances are it'll either not deliver the voltage/current needed or, worse, will fry your equipment.

Why not say, in detail, what you need to do, what you have available and why ordering online isn't an option.... and just maybe we can help...

 

Yes. It might work, but it might not work very well.
See https://en.wikipedia.org/wiki/Blocking_oscillator
If anyone thinks that it will work regardless of the value of inductance, type of coil etc., they they are being rather optimistic.

Thanks for you reply. I am looking to build a small continuous electric arc (a DIY electric arc lighter), powered by 2 AA batteries in series.

As in a gas-lighter


You're going to need considerably higher voltage output than that boost converter, though the technique is similar. Breakdowj voltage of ar is approx 30kV/cm!

 

There are many youtube video's on how to do this, search on 'DIY spark lighter'

Is this one better?

 

That'll probably work if you can find the bits...the transformer might be hard to find. But if you can buy them online from AliExpress you could just buy a ready-made one probably cheaper!

 

This is the easiest I could find on YouTube but I have some doubts if its going to work.

I rarely watch YouTube videos for electronics. They're mostly a waste of time and are just trying to get you to watch long enough to monetize your time.

Post a schematic if you want more people to consider your question.

But, you're in my questionable category. You don't know much about electronics and want to build something that could be used for nefarious purposes.

I have build a lot of simple circuits before but I don't know much about inductors so I asked. I don't have a schematic yet.

Little knowledge and high voltage circuits aren't a good combination.

You should be able to make one from the video.
