      @RAndrewNeal 4 роки тому +1

      Yeah. Do you know what it costs to buy a little drill press for this purpose? It's unjustified. So I got a ~$20 drill press stand (for hand drills) and a ~$10 hobby motor that came with a chuck and bits, and I was rolling with a $30 PCB drill press, give or take a bit. The things that I already had though were pieces of rubber to make a spacer because the clamp on the drill press stand was too big, and a 12V DC power supply to power it.

      You could make pcbs for free but one thing that maintain people to still making pcbs at home is the shipping time and cost of the shipping is not the pcb price is the shipping. If you live out of china there is always a significant amount of time to wait until the pcb arrives , those times can be at least 1 month for america or one week but with a shipping cost of 30-50usd. If you can send me pcb's with one week $10usd shipping I'm yours.

      Must use Laser Printer for transfer.
      Laser Printer prints with plastic toner powder(not ink), that can be transferred to copper PCB with heated iron.
      If you don't have a laser printer, you can have printed by local print shop of your choice, like Kinkos, FedEx, or at your workplace.
      Most large large copy machines use Toner/Laser Printer inside for making copies.
      If you can print with inkjet at home, then you can have copies made on a copy machine that uses toner/Laser printer for making copies.

      xmrtuvgs my bad, I must not have typed what I was thinking, LOL! Years ago, I bought a somewhat cheap High-res Samsung printer for this purpose.

    This is real diy, but I don't understand why you not processed on reverse side as you did for other side? Wil it not be washed out as it's only printed ink

    Love the ghetto setup :D Thank you so much for this. I hate it when someone states "at home" and uses machines that cost tens of thousands of dollars. As if we all have that much money to spend. -_-
