    Thanks, Charlie! The plating is really lovely. Holler if you make some interesting sounds or music with it, for sure!

    will do, its hooked up to an x0xbox and a kaossilator so we’ll see where it goes.

    Hi Charli. Looks very nice.
    How do you plate vias? Chemically? Or you’re adding some kind of sleeves into each hole?

    I also made my homebrew PCB, but had to redesign it and modify the original layout to eliminate all vias on component pins. I had to make dozens of additional vias and solder a bit of wire into it. This was pretty time consuming.

    I just wonder how you do it…

    Doing a big write up on  how to etch boards, but the short version is

    Drill holes, and route out board
    fill holes with conductive ink
    bake the board
    chemical bath, electrodes, with reverse pulse or pulsed power with the correctly calculated amperage
    clean and neutralise
    isolate traces
    and thats it

    takes about an hour to fill the vias. its  a home made chemical solution with CuSo4 and laxative

    …and laxative? Really interesting…
    Your method seems quite intriguing. When you finish your write up, please let me know, I’d be glad to read in detail how you’re doing it.
    What kind of conductive ink is that?

    I’m sorry, I misspelled your name in my last post!

    Yes laxative is usually PEG which acts as a leveling agent 

    Will do.

    Starting making another one, we were getting some audio noise that wasn’t the usb, probably a copper trace shorting someplace.

    Going to build it audio side first and check the noise as i go along

    I dig the retro ‘antique’ look of the board this time.
