A SOYUZ SPACE CLOCK REPLICA

If you like the retro look of old Soviet space hardware, then this replica of the model 774H Soyuz digital clock by [David Whitty] might be the perfect accessory for your desk. Forgoing the original stack of ten jam-packed circuit boards, [David] used an Arduino, a GPS receiver, and a handful of other common parts to create a convincing reproduction.

He also made some functional changes to make it better suited as an ordinary clock for us earthbound folk. If you want to take on this project yourself, be prepared for some real metalwork. No 3D printing filament was harmed in building this project. It’s based on a pair of heavily modified Hammond cast aluminum enclosures, with over 1 kg of lead ballast added to give it the appropriate heft of the original. The GPS patch antenna is cleverly hidden on the rear interface connector, but a discrete hole for a USB connector gives away the secret that this isn’t an original. The software (free for non-commercial use) and build notes are available on his GitHub repository.

We covered [Ken Shirriff]’s fascinating dive into the guts of a real Soyuz digital clock back in January. If old space hardware is your thing, you should definitely check out this teardown by [CuriousMarc] of the 653B, the 1960s-era electro-mechanical predecessor to the 774H. Thanks to [CuriousMarc] for bringing this project to our attention.
