Quiet Orbit QO-R1
A USB-C powered desk ornament: four amber LEDs at the corners of a 40 mm square, each on its own hardware-PWM channel of an ATtiny84A, fading independently on four phases. 57 × 57 mm, two layers, no data, no PD, no radio, no battery, no controls.
⚠ This board has never been built
No PCB has been fabricated from these files. Nothing has been powered on. The firmware has never been compiled, because no AVR toolchain was available where it was written, and it has never run on hardware. Every manufacturer part number in the BOM is marked UNVERIFIED by its own author, and at least one fitted part is known to be the wrong choice.
The files pass ERC and DRC. That means the copper is consistent with the schematic and with a set of design rules. It is not evidence that the circuit works.
Do not order this board expecting a working lamp. Order it to look at, to fork, or to fix.

Background
On 21 September 2026, Paras Chopra posted that he had asked an AI model he calls Astra to design a piece of hardware for itself. It chose four softly blinking lights powered by USB, and produced a PCB, a casing and an email to a manufacturer.
The same day we gave that post to copperhead as a brief and shared the result. This repository is that build, with its source files. It is an independent design that started from the public post. No files, images or schematics from the original project are used here.
