    Question: why didn't you run wire from the pad directly to the connector instead of from the pad to the membrane?

    • @GadgetUK164
      @GadgetUK164  5 лет назад +2

      The copper tape has a good adhesive on the back, so it stays stuck down really well. If you were to try and use the conductive ink to secure a wire, it will break off very easily with any movement. The conductive ink does not set hard, it sets soft - like silicone almost, but it is conductive.

    I'll be adding a roll of copper tape to my supplies. My A500+ has a Samsung keyboard where the membranes aren't reproduced by anyone so this repair method may come in handy in future! 😎👍

      Wow the Samsung Keyboard was a very very early Keyboard (I have one also) so I'm surprised you had one in a 500+ Was it your original machine or did you buy it second hand?

      @@005AGIMA Yeah, the samsung keyboard in my A500+ isn't original. The whole machine is made up of parts I acquired over the years, including a repaired varta damaged motherboard. The case came from an old Rev6 machine where the owner had painted it in thick red gloss paint which I spent days scraping off. 😁🤣

    Top video Chris, I always have copper tape and aluminium tape at hand it's very versatile and can be used for many different things. I also think sellers are charging way too much for new keyboard membranes, I agree £25 for a new Amiga 500 keyboard membrane is way over priced, I find it hard to believe those Amiga 500 keyboard membranes cost any more than £5 to manufacture in the first place.

    • @HeyBirt
      @HeyBirt 5 лет назад +4

      Getting the tooling done for a membrane is several hundred dollars and unless you are getting many thousand made at a time it will cost much more than $5/each to have them made and that does not include tooling costs.
      Be thankful some folks are willing to invent a few thousand dollars up front to get membranes made and then sell you one for $25.

    does this apply to an A2000 later era keyboard? I'm curious if the A500 membrane works in the A2000 keyboard. I'm thinking worst case scenario of an A2000 keyboard had contacts that need more than simple cleaning.. like if maybe something dissolved some traces and where replacing would be needed. I can't find "A2000" membrane replacements.. but I have seen them for A500 and A1200 and A600..

    Mate, I have to comment on the subject of using makeup (again,lol). The advantage of having a wife and two teenage daughters is that they leave their make up all over the bloody house - which is quite convenient and they rarely, if ever, notice that it's gone walkies. If it's nail varnish remover, cotton buds and pads, soft brushes, nail varnish or that white fine tipped pen (absolutely have no idea what they use that for...) it's whisked off to narnia (aka my workshop) never to be seen again. I'm a bit of a magpie and suffer from shiny kit syndrome it seems.
    You might make use of some veet hair remover....gets rid of pubes quicker than a welding torch apparently. ;)

    • @GadgetUK164
      @GadgetUK164  3 года назад +1

      It's more likely to be a bad solder point on the keyboard MCU (The large 40 pin DIP chip on the keyboard PCB). Or in many cases the chip needs swapping. Membrane issues will cause keys to not work, but they cannot cause the LED to flash (unless perhaps its covered in liquid).

    I use a scalpel to remove the cover on flexible ribbons etc. Very gently drag the scalpel across the surface pulling backwards so not cutting but dragging (if that makes sense). Need to be really really careful though as any slip and the knife is straight through it.
    BTW that copper tape is great stuff. I seen retro man cave use it on the bottom of the gbs8200 scaler to reduce the artifacting on the output. If not tried that myself yet but might be worth a look. Never crossed my mind to use it for repairing stuff as you did so will have to keep that one up my sleeve for the future.

      I used conductive ink to join the copper tape. I could have just used conductive ink (and I have done that in the past, where the break is say a few millimetres in length), but in these cases the breaks (dark trace areas) were very long and at the point where most keys were broken on the left side of the keyboard it would have been near impossible to paint 5 or 6 traces right next to each other for such a long distance.
