[chbot] Robotics Group meeting, 5 Idris Rd, 6-30pm, Mon 20 Oct 2025 report

[Mark Atherton]

Hello everyone,

Good turnout with 36 attendees, and lots of huddles-of tech-talk. $52 + 
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

Saw Dave Jagger earlier this month; he will be our guest speaker for the 
15th Dec meeting.

Spent a morning at Ashlin’s with his PDP11. Amazing restoration job;

Went to Nerd Nite at Rolling Stone near South City mall. Fun and 
interesting evening, https://christchurch.nerdnite.com/

Mark presented "Dolby Digital, The Backstory". Several individuals at 
Robotics have asked for this talk, and several groups have taken an 
interest. This was the first public run-through and went pretty well.

Andrew talked about his full-sheet kickstarter laser-cutter, and brought 
in some sample work.

Darren talked about image generation using AI.

Andrew E talked about 3D printer switch panels
