Fun with Reversibility
1. Santa Cruz Weather Station
Most Particle Monitor shelter parts fabricated.
| Part | Quan. | Designed? | Fabricated? |
|---|---|---|---|
| Vent connector mount | 1 | * | * |
| Vent connector cover | 1 | * | * |
| Vent mount | 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 | * | partial |
| Vent/UV mount | 1 | * | partial |
| PM Cable assembly | 1 | * | (1) |
| UV Cable assembly | 1 | * | (1) |
(1) Likely will just reuse previous assembly
1.1. Next step
1.1.1. Finish Vent/UV mount
1.1.2. Build cable assemblies
1.1.3. Test in Jig
2. Marble Computation
Fascinating subject as it turns out. The discipline of "Reversible Computation" appears to provide a good basis for computation with rolling balls, as it also is the basis for quantum computing. Now getting a better understanding of CNOT and related combinatorial logic structures.
Started https://github.com/daniel-kelley/xtg to prototype gate structures of Boolean functions.
Prototyped a straight rail and a helical lift with 14ga copper wire.
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. Soap Molds
Printed a shallower top. Still not quite right, but workable.
3.1. Next steps
3.1.1. Make sure mold doesn't leak.
3.1.2. Have Annie try it out.
4. Sun Ultra 10
Trying to see what state it is in. Fires up but no video. Need DB25M to debug over serial port.
4.1. Next steps
4.1.1. Serial debug
5. Apple iMac G4
Building userland may be a PITA due to lack of RAM. Build would often segfault.
5.1. Next steps
Not sure.
6. Davies Brothel
Next hearing: 02 September; Department 37
7. Linux Audio
7.1. 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.
7.1.1. Next steps
Loop analysis
7.2. CSound programming.
The FORTRAN of computer music. Getting up to speed.
7.3. Faust programming
7.3.1. 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.
8. EPICS
8.1. Next steps
8.1.1. u3scpi network port testing
8.1.2. initial EPICS interface
8.1.3. u3scpi analog/digital port reconfiguration.
9. Brini Tracker II
Suspended for now.
9.1. Next steps
9.1.1. Validate remaining standard GPS messages
9.1.2. Investigate GPS chipset data logging
9.1.3. Investigate LoRA radio interface
10. wktcolor
10.1. Next steps
10.1.1. Explore how to get a minimal coloring
Need a specific planar graph four coloring.
11. wktplot
11.1. Next steps
Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem. Explore biological cell Voronoi organization
12. AMDGPU
12.1. Next step
12.1.1. Reverse engineer HSAKMT programming.
13. Ninja v Make
13.1. Next Step
13.1.1. clean simple measurements
14. GMP Forth
14.1. Need to think about adding floating point support
14.2. Port to non-Linux OS
15. ca-r
Tier data finally deprecated so processing is removed.
15.1. Next Step
None.
16. Swocer
16.1. Most crashing addressed
Nullified 'handle' API free functions helped a lot. Still see some errors in operations.
16.2. Added outline for 'bottle' test
Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.
16.3. Next steps
Swocer future. Check out what's needed for gears.
