    I need a part # of a SCR to use these 10 Computer caps 220000 uf @ 10 volts

    I want to make a cap discharge spot welder but I need a SCR that will handle about 125 amp or more and be able to control it with a Basic Stamp. Here is the story about this spot welder

    I bought it on EBay It came to the house and I pug it in wall the battery charger worked the welder controller would work but did not put power to the welding transformer because two pins on the SCR where broken loose on the control board repair that and now it burn the wire at the plug off
    so I got some 3 wire so cord 14 gauge and a 20 amp plug and try to run the welder again now

    I tripped a 15 amp breaker so I put a 20 amp breaker and tripped that one as well

    So I send the EBay seller

    an email telling them the problems that I was having with this welder

    So they send me a new transformer with the Probe arm and a new SCR with a heat sink

    and this transformer tripped the breaker as well

    so I took both transformer and hook them in series And # 8 battery cable on the secondary and now I can melt wire and not trip the breaker
    so now I have an extra set of probes to make a cap discharge spot welder

    I would not send back this welder because it would about $ 100.00 to ship it back to China

    I will hope fully will get this weld to work now

    I bought the computer caps on EBay 6 @ $7.00 each and 4 @ $ 8.75 each

    One of these caps can light a 50 watt 12 volt light for a second with the charged to 10 volts

      Reverse engineering of DoCreate DHJ567 handheld spot welder
      by spleenharvester
      Hello everyone

      I attach a schematic and teardown photos for the DoCreate DHJ567 handheld spot welder. I bought this welder for temporary use while my supercapacitor welder was waiting for replacement parts. It cost only £24, though there is a screenless version available for £17.

      Performance: The absolute maximum it can handle appears to be 0.15mm of pure nickel. Reliability was not great - welds were very inconsistent, ranging from weak attachment to burning through the strip. However, I was able to build a 5S2P pack without losing any cells. It's a bit difficult getting...

      monitor AORUS AD27QD - short circuit and tripped breaker.
      by sew333
      Hello. I had a good monitor AORUS AD27QD. Yesterday when i was sleep i left monitor on like always. When i woke in morning there was not power in house. Something tripped breaker/fuse.
      When i turn up breaker and power back in,monitor just refused to turn on. So monitor i guess tripped breaker somehow and make short circuit.

      PC starting normally. Only monitor get damaged.
      During night only pc was running and monitor. Other devices was off.

      Is this possible that monitor can trip breaker?

      PS5 digital / No Power / No Beep / Good power supply
      by MisterAIL
      Hi everyone,

      Brought a non functionnal PS5. Apparently only a bad PSU...
      No beep, nothing.

      After some tests i found this :
      - PSU is fine (12 volts stable)
      - 12 volts line is shorted
      - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
      - By the way, nothing change. No signal, no power, no beep.

      Mesuring all rails with my workbench psu (12 volts input)
      - 0.00 amp drawing
      - 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...

      Dead Dell Latitude 5420 not receiving 20 volts from USB-C charger
      by BTubbs200
      Hello,

      Dell Latitude 5420 P137G
      Board: LA-K491P REV A01

      I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

      Board seems to have no shorts, all power rails are fine and show high resistance.

      When charger is plugged in, voltage is present in 3.3V rail but absent in others....

      MPJA 10 AMP @ 0 to 30 Volts Switching Power Supply Cap Fault
      by sam_sam_sam
      I have this 10 amp 0 to 30 volt switching power supply that decided to have a 630 milliamperes draw on it at 0 volts

      I open it up to find non brands name capacitors in it

      I am not sure how this switching power supply is set up

      Could someone please explain how this power supply works

      Here is the capacitor ESR results

      (1) 47uf@50 volts 0.46
      (2) 47uf@50 volts 0.45
      New 47uf@50 volts 0.35

      (1) 100uf@25 volts 0.34
      (2) 100uf@25 volts 0.35
      New 120uf@50 volts 0.08

      (1) 220@25 volts 0.13...
