      He doesn't provide the gerber files, only the kicad projects so you can generate your own using KICAD, to the specific requirements of the manufacturer you want to use (I think Kicad has pre-configured settings for bigger manufacturers?). Pop in to the discord if you like, some members have generated gerbers they can share with you

    Use a flux paste. You don’t have to hold the components while you solder them. Once you get the hang of it it’s far quicker than through hole. You can place several components at a time.

    Enjoyed the video very much, although I kept yelling "too much solder paste!" at my computer screen. I had to learn that in the same way, too! What is everyone using for the probes? Any working better than others? I'm about to spring for the latest 6.0 version pcb (I already have a pico 2 in hand!) & start the project.

    Good afternoon. This board is a testing ground for different chips and unfortunately CS4344 or CS4334 was not supported in firmware. We settled on TDA1387 or PCM5102A. Also, my firmware can be controlled completely with a joystick from the on-screen keyboard - the second item in the main menu. Where can I send the documentation translated into English?

    I have the Saleae Logic Pro 8. I tried one of those cheap ones like what you first showed. I found it to be useless. Probably because it wasn't fast enough for my signal, but I can't remember now. The software for the Saleae is great. My only complaint is i didn't get the Logic Pro 16, although I really haven't needed more than 8 channels yet. I'm sure the day will come when I will.

    • @HappyLittleDiodes

    Hi dude, not seen you in a while. I`m just working on using an Arduino as a voltage sensor on ZX Spectrum so if they go out of spec an alarm will sound to protect the board. I have the 12 volt and 5 volt sensors sorted but can not find the minus voltage shield to measure the -5 volt rail. I did see it on UTube somewhere. Anyway. hope you ok and not picking up too much static off your moustache. :)

      Good question, I'm no expert but I think that knowing the temperature on the inside and outside of your insulation would be a good indicator of its performance. If you decide to get one there's a link in the description that I think applies a discount (it seems to for me)

    Really if you tests 40 years old capacitors in capacitance and ESR, you can see all are correct. The better things have a ZX Spectrum I think was the capacitors. It's not necessary remplace in general any one.
