Just found a 1000kV arc generator on AliExpress.. huehue :v
1 megavolt? That's the usual voltage level on lightning bolts. And with air's breakdown voltage of ~15kV/cm (could differ depending on humidity), you'd need nearly a meter of distance between the prongs *and* be able to achieve an arc between that distance without having shit arc internally, before you could ever reach 1MV. Yet arc generators' prongs are usually within 1cm of each other. I'd give it 10kV at best.
Also, they're generating the voltage of a lightning bolt for €3.65 apparently.. way too good to be true. Even components able to handle 10kV are quite costly, and components having a breakdown voltage of over 1MV is completely unheard of. I'm gonna buy one of those puppies to see how the circuit is designed and to zap the shit out of those bloody mosquitos in here - the only women that love me :'( - but I wouldn't be surprised if it just boosts the output voltage up to whatever until it can arc and short out. Completely unregulated of course.. which is fine but eh, I doubt that any of those components are rated for 1MV so probably the regulation is in smoking components acting like fuses when the prongs are too wide apart :v
As for the purpose of this rant.. nothing in particular really. Perhaps it'll educate some, I don't know. Just wanted to put it out there :)
Also if you'd like to watch some video material about this, you may find ElectroBOOM's coverage interesting: https://youtube.com/watch/...29 -
I once started developing a chatbot, super easy and simple, a MySQL backend for the QA stuff.
I then started to think on the most modular way to "reuse" the same QA system, and got stuck on it for around 3 days (while doing other things).
Obviously the chatbot stuff could'nt leave my thoughts , and I remember it was a saturday morning, I woke up super excited and just started writing down what my sleepy me was engineering while I was dreaming.
I still have the same system implemented and I'm expecting that some day, in the future, I'll have to rewrite it, and I hope "sleepy-me" helps me again, this time with an actual interesting solution haha
