[chbot] Robotics Group meeting, 5 Idris Rd, 6:30pm, Mon 21 July 2025 report - Dave Jaggar special :)

[Mark Atherton]

Hello everyone,

Great turnout with 38 attendees, and lots of huddles-of tech-talk. $50 + 
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 his GX35 dyno project; a GX35-based four-stroke test 
platform with servo controlled throttle, processor controlled 20-600W 
load, and Android GUI.

He also talked about his long-time interest in FPGAs, which are purely 
digital. An analogue version has been spotted. Matt Venn (Tiny Tapeout) 
recently interviewed Peter Kinget, creator of  MOSbius - A field 
programmable transistor array. Fascinating project.

Dave Jagger was our guest speaker. He worked for ARM for many years, and 
was architect for many other their microprocessor families. Stunning 
talk, that received lots of complements.
