Episode notes
Watching A Deep‑Space Capsule Land
- Elliot watched the OSIRIS‑REx sample return live and compared the retrieval to picking up high‑altitude balloon payloads.
- He noted the capsule was very small and landing near a road made recovery easy.
DIY Vibrating Bowl Feeder Build
- France built a 3D‑printed vibrating bowl feeder after hundreds of hours of tuning and prototyping.
- The build used a heavy concrete‑filled base and a bipolar electromagnet driven by DDS to get the motion right.
Open Source Hardware Has Different Tradeoffs
- Precious Plastics uses timed exclusivity for Patreon funders but intends to release designs under Creative Commons later.
- The hosts discuss that hardware 'open source' differs from software because plans, not code, are the main artifact.
