62 BAR: a miniature DJ instrument — assembly visualization from the creator’s source
eminimnim · assembly visualization

What the hardware does

A Raspberry Pi coordinates a motorized platter, touchscreen, keys, encoder, fader and audio interface inside a custom enclosure.

How the agent helped

The creator credits Codex with software and motor firmware as well as CAD and an assembly animation. They report assembling a physical prototype after the animation; motor feel and mechanical details are still being tuned.

Before you build

Creator says physical prototype assembled after the linked animation. Motor feel and mechanical fit remain under development; not a finished retail product. The source image is an assembly visualization, not a photograph of the later assembled prototype.

Physical prototype, not a finished retail controller. The source’s assembly image is a visualization; it does not verify mechanical fit or current motor feel.
