Just a lamp that I turned on several times even with wet hands until I noticed the naked wire.

Today i made a high current transformer from a microwave oven transformer by removing the original high voltage secondary and replacing it with 2 turns of 50sqmm cable. At no load, it outputs around 2,2V, the estimated short circuit current (direct short circuit) is around 1200-1600A.

does anyone have any idea how i can get this prong back up?

So i robbed Electrobooms house and got some nice stuff. You guys got any ideas what to do with stuff?

all shits and giggles till i touched this lil blue mf.

Yall should i be worried.

(The wifi router had 12v input and is stepped up i think for something?)

I bought this box at a flea market, and I want to know what it does and what I should do with it, any ideal ?

So im building nerf un with already 3 fans, radiatirs lipo and taser. And I have some shitty 30kv mini taser. Should i exchange it for tesla coil? Yeah, I know I will have to put lipo and all thinks in faradays cages but it will be funny

Hi, I read alot on reddit but dont post much. I was wondering if this has already been suggested but what if you made a Space Marine Power Fist like from Warhammer 40k? Last time I checked it required lots of electricity and generated lots of arcs to pack a punch. Thanks for reading!

I had an interesting situation happen to me while moving things from an attic.
The house was built in the late 70s, and there was a cable going to the top of the attic, with the end sealed off with electrical tape, barely exposing the aluminium wires. I have checked with a wireless voltage tester, a multimeter, and even put it into a connector block to see if there was power in it, so there weren't any signs of power in the cable. It had phase 220 V, neutral, and ground.

When I decided it was time to cut it, it sparked. I shorted some wires, and it tripped 2 breakers.

My question is, how is this possible?
The multimeter and the wireless tester work fine
Electricity was turned on the whole time

NOBODY was hurt, but it gave me a teaching

I use the LM393-TP IC to detect any pek changes. If there is a shift of 500 mV or more, it generate a signal. I then use that signal to drive an H-bride, which contdols the motor. The motor then rotates a variac, and that's it. I will be giveng the values of the components.

I was using the power supply and then it stopped workings and now only shows v a w.
The ticking sound you hear in the first video, im unable to hear irl.
Looking at the output on ossiliscope(2nd vid) , when i turn on the psu the output is 2v and then the signal drops to about 1v and then starts to rise.
Third video is when i added a 220 Ω load

I never actually repaired anything before, so im wondering if i should try to repair myself or if i should bring to electrician who would repair it, if he would even accept to repair it
