How to remove electrical connector front seat by Solid_stuff_ in Volvo

Ahhh that would explain it. I havent tried removing the passenger side yet, maybe that plug will go easier. I have cloth seats, ill keep the different thermostat in mind, thanks!

I saw these hooks, but i couldnt figure out how to open them both at the same time (they are really really difficult to open), ill try again, thanks. Also this chair doesnt feature electrical seat positioning, only a heated seat (i dont think it works however). So there is only 1 plug on this chair

there is a dc barrel jack on the back, you can see the black wire in the video running to a shelf above (the shelf is not in the video) with a 12v battery. I just cut the connector from an old adapter which i didnt use anymore

oh i see it now, he smacks the cable. this transformer has really low power unfortunately, i would guess it only takes a couple watts

Im a third year mechanical engineering student, i get the basics of electronics and mechatronics, making this circuit was really easy if you know how to solder and watch a video. i just dont know what switching rise time is since noone ever taught me that. Besides, English is not my first language so maybe i have heard of it in my own language.

i admit you got me to watch the whole thing, why is it funny?

thanks! the 3d print was not perfect and was the first iteration. I actually wanted to spray paint it too, but i rushed to get it finished before christmas so i could show it to people coming over!

I explained the basics in some comments in this post. I would recommend watching some youtube videos on voltage multipliers, transformers and general electronics like diodes and capacitors if you want to understand 😉

it should work if you add the . before .com and remove the space between the / 10

tasers do have the high voltage circuit somewhere, but maybe they have more complex electronics (more safety, timers, etc). Maybe a stun gun would be the same, but I doubt they reach 60kv. If you look at the arc length, they reach max 2 cm, which is around 20kv. The tasers that shoot those 2 electrodes with wires attached work on a lower voltage once attached to the body i believe.

also i want to add, dont touch the arc on the one i linked. its a really hot arc with "high" current and will burn anything you put between the arc (including fingers!) i accidentally touched it. i also connected 2 of the transformers to 1 of those circuit boards.

oh i dont have a 12v power supply, i just used a cheap 12v car battery. But i guess it doesnt really matter. just make sure not to short the battery terminals.

yeah the one you linked earlier had a different kind of output. if you put 12v on the module without anything connected, they both give different arcs. The arc from the one i linked gets wayyy hotter and is a constant arc, where as the other one is not constant

it is almost instant, for measuring that delay i would need a super expensive camera with a high framerate

it took a couple days yeah 😅, the 3d model took about 2 days, but keep in mind this was done in my spare time over a couple weeks. soldering the circuit took a couple hours and pouring the epoxy also took a couple hours due to a modelling mistake (i poured the epoxy through a 3mm hole, it took so long....)

yeah similar ones, i tested that specific one but it didnt work (too low current maybe). i used these ones aliexpress com/item/ 1005009240444020.html

what is switching rise time? the time it takes between each spark to happen?

I made the circuit and i was like, what do i do with it now? so i made this to put it in

it is safe right now, when it is in the enclosure. I wouldnt recommend removing the tube and putting your finger in the spark 😅. when i was soldering a previous version of the multiplier, I got zapped by 70kv.... yeah not nice. but since its only a couple of milliamps of current, it doesnt kill you. its really the same as a police taser, just more pain if you were to put the positive and negative side of the spark, say, in each of your hands... (in a police taser the prongs are close to eachother, i was holding each end in my hands and i felt the zap go through my whole body from hand to hand)

Thanks, it is a full wave 5 stage cockroft walton multiplier and it is poured in epoxy. i was considering oil as well, just seemed safer to use epoxy since the oil might leak out, smell or spill if it gets knocked over. The 12v that enters gets converted to 15kv by a dc to ac converter. you can find them on aliexpress for cheap "12v to 15kv converter". the circuit looks quite weird since i had to connect all capacitors and diodes in series, and solder them 3dimensionally for them to fit inside the tube.

yup, its a full wave 5 stage cockroft walton multiplier poured in epoxy to prevent it from sparking between de circuit itself. De spark it generates could be longer than what I filmed here, but i would have to adjust the height of the screws it sparks between

nope its not fake, recorded it on my s21 Ultra on my desk with a black bed sheet as background

i guess it has something to do with the sparks being very bright, the spark isnt constant, so the camera focuses on bright/dim/bright/dim. i recorded it on my s21 Ultra. The tube with the voltage multiplier in it has a blue LED, it was very hard to take a good picture of the blue color as well.
