- RepRap 3-D printer completion was celebrated as a milestone for open-source hardware in the channel.

- A live experiment in WordNet-based conceptual clustering was attempted: kanzure tried to group search queries by their WordNet synsets, found the results unsatisfactory, and posted a screenshot of the noisy keyword clusters.

- The group discussed building an open-source repetitive transcranial magnetic stimulation (rTMS) device; superkuh provided a detailed bill of materials (pulse capacitors $20–$200, microwave-oven transformers, copper pipe, diodes, etc.) and noted that semiconductor switching adds $300–$500 while spark-gap switching is “extremely loud.”

- Superkuh shared photos of a single-pulse TMS coil and capacitor bank he had already built for peripheral-nerve stimulation, and stated he has been planning a full rTMS build for five years.

- Ybit maintained a personal project list (http://ybit.ath.cx/misc_docs/projects.txt) separate from the main trans-tech.yaml database, prompting discussion on how everyday tasks like winterizing chainsaws or cleaning saucepans could be captured in structured YAML “how-to” formats.
