Still Praying for Rain
1. MIT OCW
1.1. 18.01 - Single Variable Calculus
1.1.1. Sessions 36-40
1.2. 8.01 - Physics I - Classical Mechanics
1.2.1. Sessions 20-22
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
A little light display for Halloween this year. Mostly based on the Garden Orb, running on a Feather M0. Drives a single light so far.
3. Marble Computation
Collected materials (thin copper plate, copper PCB blanks) for prototyping.
3.1. Next Steps
3.1.1. Continue Reversible Computation Study
3.1.2. 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.
5. us-index-map
5.1. error analysis
Started an error analysis on the USGS topomapsall.csv index file. Nothing abvious pops up, and the error reported by Maureen would be impossible to catch anyway.
6. Sun Ultra 10
Trying to see what state it is in. Fires up but no video. Need DB25M to debug over serial port.
6.1. Next steps
6.1.1. Serial debug
7. Apple iMac G4
Building userland may be a PITA due to lack of RAM. Build would often segfault.
7.1. Next steps
Not sure.
8. Davies Brothel
Next (plea) hearing: 28 October; Department 37
9. Linux Audio
9.1. 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.
9.1.1. Next steps
Loop analysis
9.2. CSound programming.
The FORTRAN of computer music. Getting up to speed.
9.3. Faust programming
9.3.1. 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.
10. EPICS
10.1. Next steps
10.1.1. Started CGR-101 SCPI interface
10.1.2. u3scpi network port testing
10.1.3. initial EPICS interface
10.1.4. u3scpi analog/digital port reconfiguration.
11. Brini Tracker II
Suspended for now.
11.1. Next steps
11.1.1. Validate remaining standard GPS messages
11.1.2. Investigate GPS chipset data logging
11.1.3. Investigate LoRA radio interface
12. wktcolor
12.1. Next steps
12.1.1. Explore how to get a minimal coloring
Need a specific planar graph four coloring.
13. wktplot
13.1. Next steps
Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem. Explore biological cell Voronoi organization
14. AMDGPU
14.1. Next step
14.1.1. Reverse engineer HSAKMT programming.
15. Ninja v Make
15.1. Next Step
15.1.1. clean simple measurements
16. GMP Forth
16.1. Need to think about adding floating point support
16.2. Port to non-Linux OS
17. Swocer
17.1. Most crashing addressed
Nullified 'handle' API free functions helped a lot. Still see some errors in operations.
17.2. Added outline for 'bottle' test
Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.
17.3. Next steps
Swocer future. Check out what's needed for gears.
