PCBs are here!

Today, I just recieved the first ten PCBs for my chiptune synth kit. The black solder screen looks really good. 😀
I’m now waiting for the last parts to make a prototype and to design its case.

    Any thoughts of selling fully built units?

    I would buy a prototype if need be,

    Congratulations on the pcb it does look very sleek

    Almost forgot,

    No Arduino bootloader is even better then before,

    well done

    I also wanted to ask,

    Would we be able to use our own samples on the unit?

    In one of your videos you use some 4bit drum samples, is there any plan to allow users to upload there own sounds via some form of software? or uploader tool?

      I still have some work to do, and maybe I will be able to prepare fully assembled units. 🙂
      On a medium term, users will be able to send their own samples. I think I’ll make a custom software interface with Ctrlr to do so. (A very good soft! )

    Hi ,

    Thanks for the reply :),

    Presuming your new layout does not include usb or anything else to talk > to the synth,
    perhaps a simple midi dump programme to convert and send samples to the unit?

    Im not sure how you actually stored the samples in your previous demo but I presume theres some onboard ram or space on a chip somewhere that allows you to write/read and & perhaps store sounds?

    Im not sure but I am really excited about the project.

    Also would your ym streamer work with this design to listen to old ym songs?

    I justed wanted to say, VERY GOOD JOB! i’m excited to use it !
    Hope you release pcb layout?

      Sure, the PCB layout will be public. 🙂

    AY8930 maybe a better choice because you can have separate duty cycles (8) per voice.

    its a drop in replacement but has extra features that will be worthwhile.
