A week of virus first and space seconds
First Moderna shot Second Space X crew launch Second Ingenuity flight
1. Santa Cruz Weather Station
Test cable constructed Test Jig program complete Particle sensor dead I2C sensors work but have significant corrosion
1.1. Next step
1.1.1. Order replacement sensor
1.1.2. Order Adafruit 4649
Needs some more circutry (I2C A/D) and 555? but may be alternative to Plantower sensor if it can be calibrated side by side.
1.1.3. Clean BME680/VELM6075 boards
1.1.4. Design more robust instrument shelter
2. EPICS
No progress. Now that the Brini Tracker A/D is working (which was the original motivation for getting U3 stuff working), this is no longer "critical path" - not like anything is critical in this list.
2.1. Next steps
2.1.1. u3scpi network port testing
2.1.2. initial EPICS interface
2.1.3. u3scpi analog/digital port reconfiguration.
3. Brini Tracker II
No progress
3.1. Next steps
3.1.1. Validate remaining standard GPS messages
3.1.2. Investigate GPS chipset data logging
3.1.3. Investigate LoRA radio interface
4. wktcolor
4.1. Coloring with igraphvertexcoloringgreedy
When the doc says "coloring is not necessarily minimal", it's true.
4.2. Saves output in GraphML format
4.3. cleanup
4.4. graph simplification
4.5. smoke test
4.6. Next steps
4.6.1. Explore how to get a minimal coloring
5. wktplot
5.1. wktlib: c++ export.
5.2. wktplot: read wktcolor file to label polygons
5.3. wktrand: add minimum distance parameter
5.4. Next steps
Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem.
7. AMDGPU
7.1. Next steps
7.1.1. Reverse engineer HSAKMT programming.
8. Ninja v Make
8.1. Next Step
8.1.1. clean simple measurements
9. Plumbing
Shower backed up but snaked it clean
