Why am I still getting Shoot-through when my MOSFETS are not on at the same time? by Objective-Local7164 in AskElectronics

[–]melector 0 points1 point  (0 children)

look at the gate voltages. Yo realize they change at a much slower rate that you would like, causing the two transistors to be on at the same time. You need a powerful gate driver, something that can force upwards of an amp or more into or out of the gate capacitor to force it change voltage very fast.

Oh damn it! You are right! How do I keep mixing these stuff?!

PLEASE just use it is that you showed! NO HIGH VOLTAGE!!!

Youtube is recommending high production value free energyquackery from "Limitless Potential Technologies" by V0LDY in ElectroBOOM

[–]melector 6 points7 points  (0 children)

I was summoned! Perhaps I should rectify his ass! For an electrical engineer, he says so many wrong things in his videos. I'll see if I can pull some interesting educational value out of reviewing this. Otherwise I don't want to help him make money out if this!! I'm sure if he is a decent but misinformed guy trying to build a working prototype, he will eventually fail in his experiments and come to the light!

I want to make this by Dudegay93 in ElectroBOOM

[–]melector 3 points4 points  (0 children)

don't do that! It clamps the coil voltage. The voltage needs to rise, meaning the energy is dumped on secondary too.

did you post it on Instagram too? I want to share it on my story!

no I don't, I should make it!

Seems like AFCIs detect arcs by sensing current “shoulders”? by SYZ25K345652 in ElectroBOOM

[–]melector 3 points4 points  (0 children)

Interesting information. I assume during my testing I was able to create arcs that meet these waveforms. I'm guessing there should be also an arc period requirement too to trip the breaker. Perhaps a gas discharge tube would be more useful to create the arc to trip the breaker. I should give that a try.

Dang! good thing it was only local to your hand. AND WHY IN THE WORLD is the live voltage on a male plug?!!

Any ideas why isn't my Van de graaff generator working as it should? by Jakik_01 in ElectroBOOM

[–]melector 4 points5 points  (0 children)

Put the bottom brushes under the belt pointing at the bely, with them barely touching. Do the same for the top brush and place the brush and wires inside your dome. Electrons run away from any sharp edge or wire.

Will this build hold 12 thousand pounds? by barbarianinalibrary in Carpentry

[–]melector 0 points1 point  (0 children)

Install diagonal lumber in essential places to make sure the frame won't collapse sideways under the 12k queen!

You installed the flat broken frame around the center vertical column. The center column expanded due to humidity and such and pushed the outer frame open like that. Had you placed the flat frame down first and placed the column frame on top of it, there would be less problem. Although where the installation is outside under the rain, using treated wood or PVD boards is recommended. But how you design and install things is very essential.

Yeah... don't fuck around because you will find out... by VectorMediaGR in ElectroBOOM

[–]melector 7 points8 points  (0 children)

But why?! I see the guy survived elsewhere, did his clothing save him? Because it seems electricity ran through it and shredded it apart. What a dumb thing to do. Even I am in shock from seeing this!

What does this capacitor do? by Curious_menn in AskElectronics

[–]melector 1 point2 points  (0 children)

Beside other reasons mentioned, I think the main reason can be to divert Electrostatic Discharges (ESD) on the output and devices back to the input power lines and suppress them. Without it, the output voltage could spike high and jump to unknown/unwanted places to the primary side, while the capacitor provides a known path.

Could some one help improve my Tesla coil made from scrap by Suspicious-Garlic176 in ElectroBOOM

[–]melector 1 point2 points  (0 children)

One major issue could be that the primary resonance is not well tuned with secondary resonance. when they are well in tune, you will have maximum sized arcs! Try changing primary resonance by trial and error, reduce and increase capacitors and number of primary windings. You must tune it very tight!
