[chbot] Robotics Group meeting, 5 Idris Rd, 6-30pm, Monday 19 Feb 2024 report

[Mark Atherton]

Hello everyone,

Good turnout with 24 attendees, and lots of huddles-of tech-talk. $37 + 
change (in gold, and flat-money) collected and transferred into the 
robotics loose-change jar (for later banking).

All sales from the trading table should go into the brown box on the 
wall, and are directly for the benefit of our host club, Christchurch 
Amateur Radio Club, NZART Branch 05.

Equipment donations are welcome for the trading table, but no CRT based 
product, printers, toner or items that are likely to be a disposal burden.

With thanks on behalf of the group,

Mark Atherton

Mark talked about progress on the uCPU, a small, educational, 
micro-sequenced 8-bit processor to be implemented on an FPGA in Verilog. 
ISA, Architecture, Instruction map, and micro-sequence editor are 
complete, as well as micro-sequencing of several instruction groups.

Graeme Absaslon talked about an interesting current measuring problem he 
resolved using a Raztek sensor.

Robin talked about his ultrasonic anemometer project.

Rudy discussed a high dynamic-range current data-logging problem.

Interesting YouTube content:

fascinating insight into apparently simple puzzle.

in Excel. Three instructions per second. Utter genius.
