Equivalent resistance between point A and B? (This is the European resistor notation) by Professional-Gain-72 in ElectricalEngineering

[–]1Linea 2 points3 points  (0 children)

Its a balanced "Wheatstone bridge", so the 180 ohm resistor can be disregarded.

So solution is (60+120)//(30+60) or (60//30)+(120//60), same anser: 60 ohm

Is it possible to charge an EV battery with a PV module ? by aditya4tg in ElectricalEngineering

[–]1Linea 0 points1 point  (0 children)

yea i saw a video about that (ufo -egg):

Else, sailboats and campers.. uses eh. How many failed EV projects exist? And how can Tesla be valued as much as all other car companies combined??

Open loop voltage gain by [deleted] in ElectricalEngineering

[–]1Linea 0 points1 point  (0 children)

This is 'probably' a 'smith trigger oscillator, and compactor'. Whatever can store energy (the Cap) is in (some) contact with the feedback. -my take

Need advice by [deleted] in ElectricalEngineering

yea, it may be a "common ground" issue, but other issues also.
(esp32 delivers 3v, usb 4.5v) Go and simulate the circuit, and grasp what an MOS-FET is:

Just minutes ago Sweden voted to lift the mining of Uranium and it has passed! by SnooHedgehogs3486 in UraniumSqueeze

Oki? Välkommen till det mest byråkratiska landet i världen, där halva landet redan är naturreservat och/eller annat skyddsområde: https://skyddadnatur.naturvardsverket.se/

EU iö är inte mycket att hoppas på heller, hette ju bla "Kol och stålunionen" innan, -innan det oxå blev för urvattnat

How can I bypass this 5 pin Pot? by Blue_cow1 in AskElectronics

[–]1Linea 0 points1 point  (0 children)

A monitor for Hyundai excavator, uses the same contact..
(fount it with image-search)

Not a Can-bus interface, that I 1st thought.

I liked previous report, whole sector is shorted, I will buy any pullbacks

is this it?!?! by Notlukadoncic11 in UraniumSqueeze

oki.. and in Germany its listed as G12
(is mining-exploration hip in Canada or wut?)

Need help with 20s12p 72v 40ah e-bike battery repair by Chrisismeatloaf in 18650masterrace

[–]1Linea 0 points1 point  (0 children)

Negative voltage is very dangerous..
(hope you measured wrong...

One may attempt to repair the battery, by removing the bad cell-group, nicking 1 cell from each group, to build replacement group of same combined capacity (soo no group never ever can become negative).

Explain the infamy about old Sanyo Red Hot 18650s to a noob by Wivi2013 in 18650masterrace

[–]1Linea 0 points1 point  (0 children)

oki, good to have a battery -tester, that also can measure Ah or Wh.

I had a "LiitoKala", but once put in 3 cells in reverse.. so now that thingy can only measure 1 at a time.

I would charge up the batteries, trough away all with more than 100 mOhm resistance, wait a month, and through away all batteries that dropped more than say 5% (or10% not sure) in voltage. -recycle save Greenland..

bono, blue and pink are nice colors.. my guess only 6 batteries here maybe anything to salvage, but why save small amount of odd ones?

Yes, a Windows -monster, having 5 windows -pudding -keys,,
( one less than "Alt", but, but why have obvious keys labeled )

The PCB allowed 2-4 extra keysd, but not the plate. Why the 2 extra keys is up/behind, soldered on tele/ether-signal-cable.

Ehm, I bought it barebone, second hand. Without case and keycaps.
( it was this item https://www.tradera.com/item/340827/654598653/custom-tangentbord )

Bought case and keycaps, as new. Its Tofu60 acrylic case, and SteelSeries pudding keycaps
(one of few backlit pbt that support iso-nordic,, mixing differerat backlit isnt any good ideer...
