Santa Cruz Weather Station finally ready

1. Santa Cruz Weather Station

All Particle Monitor shelter parts fabricated.

Part	Quan.	Designed?	Fabricated?
Vent connector mount	1	*	*
Vent connector cover	1	*	*
Vent mount	2	*	*
Vent Standoff	2	*	*
PM box	1	*	*
PM lid	1	*	*
PM Baffle	1	*	*
PM Screen mount	2	*	*
PM Screen holder	2	*	*
PM Inlet shroud	1	*	*
PM box mount	1	*	*
PM box mount standoff	2	*	*
Vent/UV mount	1	*	*
PM Cable assembly	1	*	(1)
UV Cable assembly	1	*	*
UV/PM Cable assembly	1	*	*

(1) Likely will just reuse previous assembly

Fixed crossed TX/RX in weather mast test jig.

Tested, installed, and retested assembled weather mast.

PM history graphs reinstated, but this was more fiddly than expected - weewx software would stop after 5-10 minutes. Eventually started working again for reasons not clear and has been stable since Friday.

Added additional checks for pms5003 synchronization is it appeared to have been part of the problem, now no longer clear it was.

Ensured that sczwx github repository matches what is actually running on hardware.

1.1. Next step

None!

2. Marble Computation

Collected materials (thin copper plate, copper PCB blanks) for prototyping.

2.1. Next Steps

2.1.1. Continue Reversible Computation Study

2.1.2. Prototype Marble inverter

Using dual rail differential logic (left/,right/1), an inverter merely switches sides. I think little "kickers" on the side should be sufficient for a purely mechanical approach.

3. MIT OCW

Preparation to start MIT Open CourseWare classes 18.01 (Single Variable Calculus) and 8.01 (Physics I - Classical Mechanics).

3.1. Next Steps

Start studying!

4. Steel Metallophone

Did some analysis on using 6 and 12 inch steel pipe for metallophone and chime construction (for Kevin).

5. Faust wasm oscillator

Built a simple web browser oscillator using Faust/WASM.

6. Soap Molds

Printed a shallower top. Still not quite right, but workable.

6.1. Next steps

6.1.1. Make sure mold doesn't leak.

6.1.2. Have Annie try it out.

7. Sun Ultra 10

Trying to see what state it is in. Fires up but no video. Need DB25M to debug over serial port.

7.1. Next steps

7.1.1. Serial debug

8. Apple iMac G4

Building userland may be a PITA due to lack of RAM. Build would often segfault.

8.1. Next steps

Not sure.

9. Davies Brothel

Next hearing: 02 September; Department 37

10. Linux Audio

10.1. pvanal to spectrogram

Enough of libriffr and libpvocf work to start pvoctool https://github.com/daniel-kelley/pvoctool. Have HDF5 output and text delimited output for octave. Can import PVOC data to octave spectrogram for display.

10.1.1. Next steps

Loop analysis

10.2. CSound programming.

The FORTRAN of computer music. Getting up to speed.

10.2.1. Next Steps

loscil demo
spectrogram loop point analysis

10.3. Faust programming

10.3.1. Next Steps

GAC Patch save/restore
LV2 autopatcher

Exploratory tool to generate (was pd, ecasound, now carla) patch for arbitrary LV2 plugin: hook up audio inputs to signal source, audio outputs to speakers, control inputs to control surface, etc.
OSC control surface

Some sort of GUI tool (knob/slider) to OSC messages. This may be as simple as a Faust UI program.
Faust/csound

See if a faust generated unit works.

11. EPICS

11.1. Next steps

11.1.1. u3scpi network port testing

11.1.2. initial EPICS interface

11.1.3. u3scpi analog/digital port reconfiguration.

12. Brini Tracker II

Suspended for now.

12.1. Next steps

12.1.1. Validate remaining standard GPS messages

12.1.2. Investigate GPS chipset data logging

12.1.3. Investigate LoRA radio interface

13. wktcolor

13.1. Next steps

13.1.1. Explore how to get a minimal coloring

Need a specific planar graph four coloring.

14. wktplot

14.1. Next steps

Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem. Explore biological cell Voronoi organization

15. AMDGPU

15.1. Next step

15.1.1. Reverse engineer HSAKMT programming.

16. Ninja v Make

16.1. Next Step

16.1.1. clean simple measurements

17. GMP Forth

17.1. Need to think about adding floating point support

17.2. Port to non-Linux OS

18. ca-r

Tier data finally deprecated so processing is removed.

18.1. Next Step

None.

19. Swocer

19.1. Most crashing addressed

Nullified 'handle' API free functions helped a lot. Still see some errors in operations.

19.2. Added outline for 'bottle' test

Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.

19.3. Next steps

Swocer future. Check out what's needed for gears.
