    PSU what component is this ?

    Put a red ring around the object in the first picture, looks like a little piece of a copper sheet that has been cut.

    I'm the first to open this psu, Why is it there ?

      Maybe spark gap, in case there's lightning or something going through the MOV or something like that?

          That's the only thing I could think of too.

              It looks like spark gap between the Primary and secondary side (one leg of the cap has that copper needle attached and another leg is another end of the point, that blue safety cap is also connected between primary and secondary to pass FCC conductive noise test.

                  VOIP, ATA REN and old analog phones ring voltage booster
                  by CapLeaker
                  I am working on a backup phone to VHF paging solution. Basically I am dealing with the old Zetron pagers. Here is how it works: One calls a number, the Zetron picks up, operator punches in the DTMF access code, the Zetron keys the transmitter and you can talk. press # the Zetron unkeys the transmitter and hangs up / times out.
                  Now this setup works good on the old land lines, but not at all using a VOIP ATA. You can call all you want and swear like a bastard at the Zetron, but it will not (even if I threaten it's life) pick up.
                  Yep, I know about the high ring voltage...

                  Hi I'm newbie when it comes to electronics repair. My copper pad where my diode sticks has peeled off what is the most efficient way to make the copper pad stick to the board? epoxy? ink mask? I want to hear your suggestions

                  Vintage fan repair, copper wire question
                  by technicalspecialist
                  I currently have a customer's vintage fan on the work bench to repair.
                  It uses an induction motor with 4 poles. One of the poles is open.
                  I couldn't find the break so i cut off the original wire.
                  I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.

                  I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.

                  The enamelled copper...

                  LG 55LN5710 backlight diffuser sheet order
                  by Lee M.
                  Hello all, new member here. I replaced the LED strips and found that the BL can be turned on with the TCON board and LCD panel disconnected. So new LED strips are working fine. Now the problem. There are 3 diffuser sheets on this set. One sheet is thicker than the others and I know it goes in first next to the LED strips. But one side of this sheet has a rougher texture than the other side. Does the rough side go up or down? The 2 thinner sheets have tabs that will only allow them to be installed one way so that's good. One sheet is what I would call plain translucent. The other sheet is whiter...

                  Ring tester
                  by tony359
                  Hi all,

                  I'd like to add a ring tester to my toolbox to test flybacks but also low frequency transformers if possible.

                  I found a few products online, some based on the "diodegonewild" design, others are different designs. Some are available to build DIY, others are not.

                  Any suggestions on a DIY one I could put together? Ideally something which would also be able to test low frequency transformers, that might be handy.

                  So far I found these two:
