First Real Rain of the Year!
1. MIT OCW
1.1. 18.01 - Single Variable Calculus
1.1.1. Sessions 41-50
1.2. 8.01 - Physics I - Classical Mechanics
1.2.1. Sessions 23-25
1.2.2. Labs
There's a version of the course (8.01x) that has labs. Gathering materials Needed for such.
- Lab Power Supply
One of the lab items needed is a power supply. Why is it that with all the piles of electronic parts I have, I can't seem to locate an LM317? Playing around with a design for a mixed switcher and linear supply. Actually 2 switchers: 24V/2A switcher -> Programmable Buck Switcher -> Programmable Linear.
2. Halloween String of Lights
Now drives multiple lights.
3. Santa Cruz Weather Station
Of course the rain gauge stopped working for the first rain. Maybe because a couple of spiders decided to take up residence inside? Spiders relocated and gauge tested. Double checking gauge with rain bucket and appropriate conversion factors.
4. Marble Computation
Collected materials (thin copper plate, copper PCB blanks) for prototyping.
4.1. Next Steps
4.1.1. Continue Reversible Computation Study
4.1.2. Prototype Marble inverter
Using dual rail differential logic (left/,right/1), an inverter merely switches sides. Now thinking an over-center spring controlling a 'side gate' controlled by a pair of sense levers.
6. us-index-map
6.1. error analysis
Started an error analysis on the USGS topomapsall.csv index file. Nothing obvious pops up, and the error reported by Maureen would be impossible to catch anyway.
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 (plea) hearing: 28 October; 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.
10.3. 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
12. Brini Tracker II
Maybe this can be simplified to just the GPS module in 'tracking' mode (which gets carried around), and a separate docking module to extract the data.
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. Swocer
18.1. Most crashing addressed
Nullified 'handle' API free functions helped a lot. Still see some errors in operations.
18.2. Added outline for 'bottle' test
Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.
18.3. Next steps
Swocer future. Check out what's needed for gears.
