Introduction: Nixie Watch Prototope_a V5. Full Datasheet


This is full source code + datasheet + all what you need to build your own nixie watch.

This is new revision of model prototype_a. Now it is archiewed version.

This watch was build for my friend. Casing - brass, bracelett -leather.

If someone need inspiration or small worklog - write in coments, or check my instagram/FaceBook page.

Previous prototype_a alpha on instructables that use Transformer as power source on this project source was lost due hdd milfunction

    That looks awesome. I love the steampunk aesthetic. Could you share some more about the details of the construction?

    On corners i used brass pipe. walls - 1mm brass sheet.

    all part was soldered using simple iron, or you can use dremel versatip photo of casing from top

    casing with laser-cutted acrylic glass (if you'll interesting - i have glass drowing)

    on this photo youll see how parts was soldered

    and just assembled casing without bracelett ears

    box-style design

    folding and soldering. Button-style charging port

    PS. is you'll need worklog - i think ill make one in a few weeks

    ps2. Buttons i cut from solid brass using latre

    2 buttons D3.8mm X 3mm height

    1 button D9.8mm X3.5mm height

    Form of button like screw (rotate letter T)
