Halloween and Almost DST Edition

1. MIT OCW

1.1. 18.01 - Single Variable Calculus

1.1.1. Sessions 57-59

1.2. 8.01 - Physics I - Classical Mechanics

1.2.1. Sessions 28-31

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

Complete.

3. Trojan Source Mitigator

tsm - tool to detect "Trojan Source" exploits

4. WWVB Decoder

WWVB time format decoder. Miserable failure so far.

5. Santa Cruz Weather Station

Rain Gauge still working.

6. Marble Computation

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

6.1. Next Steps

6.1.1. Continue Reversible Computation Study

6.1.2. 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.

7. ca-r

Issue #33 seems to have fixed itself.

7.1. Next Step

Wait for further breakage.

8. us-index-map

8.1. error analysis

Started an error analysis on the USGS topomaps_all.csv index file. Nothing obvious pops up, and the error reported by Maureen would be impossible to catch anyway.

9. Sun Ultra 10

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

9.1. Next steps

9.1.1. Serial debug

10. Apple iMac G4

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

10.1. Next steps

Not sure.

11. Davies Brothel

Hearing: 28 October; Department 37 (held) Looks like a new case C1923172, maybe it's a consolidation? Who knows.

12. Linux Audio

12.1. 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.

12.1.1. Next steps

Loop analysis

12.2. CSound programming.

The FORTRAN of computer music. Getting up to speed.

12.2.1. Next Steps

loscil demo
spectrogram loop point analysis

12.3. Faust programming

12.3.1. 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.

13. EPICS

13.1. Next steps

13.1.1. Started CGR-101 SCPI interface

Will help test u3scpi
Using flex/bison SCPI parser

Added error queue, outline for * ESE and * ESE?.

13.1.2. u3scpi network port testing

13.1.3. initial EPICS interface

13.1.4. u3scpi analog/digital port reconfiguration.

14. 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.

14.1. Next steps

14.1.1. Validate remaining standard GPS messages

14.1.2. Investigate GPS chipset data logging

14.1.3. Investigate LoRA radio interface

15. wktcolor

15.1. Next steps

15.1.1. Explore how to get a minimal coloring

Need a specific planar graph four coloring.

16. wktplot

16.1. Next steps

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

17. AMDGPU

17.1. Next step

17.1.1. Reverse engineer HSAKMT programming.

18. Ninja v Make

18.1. Next Step

18.1.1. clean simple measurements

19. GMP Forth

19.1. Need to think about adding floating point support

19.2. Port to non-Linux OS

20. Swocer

20.1. Most crashing addressed

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

20.2. Added outline for 'bottle' test

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

20.3. Next steps

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