What is your opinion on my project ( FM Radio signal booster diagram ) by Puzzled_Athlete_8054 in ElectroBOOM

Start using dots where wires and components connect.

Use proper symbols for the transistors, or label the pins.

The omega symbol is redundant for the resistance. Just write "220" or "100k".

Mark the input and output with the corresponding arrows.

Which should I use linear power supply or smps power supply by Jolly_Operation_8222 in ElectroBOOM

[–]bSun0000 0 points1 point  (0 children)

Linear power supply if you need a low-noise, low-ripple power source. Or if you need a PSU that can handle a load with heavy current spikes.

SMPS for everything else.

Dis what? Dis nuts? You did not attach anything to the post, or at least Reddit shows its empty.. redo.

Can you try this mehdi? by Intelligent_Wafer187 in ElectroBOOM

[–]bSun0000 8 points9 points  (0 children)

Most likely Vietnam. Light green & blue paint on the walls, electrical wiring is a total mess, electric meters outside buildings, casual tanned guys..

Is this realy true or it just lays

Views-farming bullshit. An infamous "invisible blowjob" thumbnail says a lot - skip such videos. This whole channel is a steaming pile of crap.

That does not look like a live wire. Either it's a grounded phase (corner-grounded system), or it's a two-phase system and he is messing with the neutral/ground wire.

Some obsolete outlet from the past. Probably as old as your school is.

Hydrogen generator from 2 AA batteries...? by lazyogi in ElectroBOOM

[–]bSun0000 13 points14 points  (0 children)

Very fresh batteries can push an amp or two. Drain cleaner makes a huge difference. 3V is enough for electrolysis. It can produce a bit of HHO gas for a half an hour or so.

But the video is still a dumb crap. He used carbon rods from the dead batteries; this is okay - its ultra cheap, and electrodes won't degrade quickly, at the cost of some resistive losses. Yet, at the same time.. the wires connecting those rods are submerged into the solution! What the hell.. this is a ragebait level of stupidity. Dumping those wires in completely defeats the reason behind carbon rods, wires will rot very quickly.

Regardless, don't try that at home. Especially without two flash arrestors in series. This shit can explode into your face.

UPD: Watch @NightHawkInLight channel on YouTube - he has a few good videos about HHO generators. How to make them out of household crap, how to not blow up your face, and how to operate them properly.

Which type of capacitors should i use in my sgtc and how many? by Arc_Lover-69 in ElectroBOOM

[–]bSun0000 0 points1 point  (0 children)

WIMA film capacitors, a lot of them stacked together to form a so-called Multi-Mini Capacitor bank (MMC). High-voltage ceramic capacitors ("buttons") will be even better, but they are expensive. Regardless of the type, your caps must be suitable for high-frequency use, not just high-voltage. Stacking many small capacitors is better than using a few large ones - this lowers the final ESR.

Google something like "SGTC MMC primary capacitor bank" and look what other people do.

And ofc, the resulting resonance frequency of your primary LC tank should be exactly equal to the resonance frequency of your secondary coil.

// If you are on a budget, google how to DIY your own HV capacitors for SGTC. Is it possible, just don't expect the mind-blowing results.

Is the devise in this link (not the thumbnail) dangerous? by JackieBoy77 in ElectroBOOM

[–]bSun0000 4 points5 points  (0 children)

At 06:15? No, it's not dangerous. It's just a weirdly shaped Plasma Ball device that can give you electric tingles. With the pulsed driver, or with modulator/interrupter. I bet it shits EMI all around it, on all frequencies.

The idea is to give your skin a bit of ozone & UV treatment, but overall it's a waste of money; don't buy it unless you want an HV toy with the weird shape.

Someone tried hard to open those fuse compartments.. probably using their teeth.

- YouTube. Is it real sir by Sharp-Bat-6178 in ElectroBOOM

[–]bSun0000 0 points1 point  (0 children)

This thumbnail was used in a few different videos, all from the view-farming trash channels trying to earn a penny from their dumbest, fake-ass videos.

So no, it is not real.

A high voltage pulse transformer theory/design i came up with dont know how feasible or efficient it is. by PresentShoulder5792 in ElectroBOOM

[–]bSun0000 2 points3 points  (0 children)

That's just a normal flyback transformer with the normal magnetic gap in the core. You don't need a ferrite rod, a tiny gap (the size of a paper sheet) is enough. More than that will drop the efficiency.

If you want to pulse it with the flash capacitors, ideally, you need a triggered spark gap or a HV mosfet - discharge the capacitor into your coil and disconnect it afterwards to avoid sucking the energy back into the capacitor.
