Updates

What changed in the machine, Mar 7 – Aug 19, 2026. Four-week entries cover a whole period; week entries cover the most recent one.

• Week Aug 16 – Aug 19, 2026 A word at both ends of every line Every tube that crosses the rear wall now carries a coloured, lettered chip at the wall, and the same word in the same colour threaded onto the tube itself.
• Four weeks Jul 19 – Aug 15, 2026 One machine, and its first hour on a bench Two machine designs ran side by side for eight days and the narrow one survived, and the controller board was powered up for the first time.
• Week Aug 9 – Aug 15, 2026 A build system, and glass fibre on the plate The flavor manifold was absorbed into the enclosure shell itself, and the first enclosure panel went on the printer in glass-filled PET.
• Week Aug 2 – Aug 8, 2026 The board meets the bench One of the two machine designs was deleted, and the controller board was powered up for the first time with half of it working.
• Week Jul 26 – Aug 1, 2026 Two machines The hardware tree was forked into a second, taller and narrower appliance, and the stripped-down Lite edition was deleted.
• Week Jul 19 – Jul 25, 2026 A build manual, and a quarter-inch line The whole appliance got a printed bench manual, and the internal water line was rebuilt to one tube size.
• Four weeks Jun 21 – Jul 18, 2026 The board becomes real Ten controller boards were ordered and the design behind them retired the next day, and a paste-layer defect was found two days before the assembled boards were paid for.
• Four weeks May 24 – Jun 20, 2026 A box, and water that stays in The subsystems were packed into a real enclosure and split to fit the printer, and the first printed flavor reservoir held water without weeping.
• Four weeks Apr 26 – May 23, 2026 First metal, and a public face The fallback vessel design was archived, stainless was tapped and welded by hand for the first time, and the project got a live website and a YouTube channel.
• Four weeks Mar 29 – Apr 25, 2026 The whole appliance, and a metal shop to build it The machine's scope grew to making its own cold carbonated water, and roughly $11,700 of fabrication and refrigeration tooling arrived to build it.
• Four weeks Mar 7 – Mar 28, 2026 A working machine, then a printer The under-sink prototype gained its full software stack, then a production 3D printer turned the project toward a manufacturable appliance.
