[chbot] Robotics Group meeting, 5 Idris Rd, 630pm, Mon 21 Oct 2024 report

[Mark Atherton]

Hello everyone,

Good turnout with 24 attendees, and lots of huddles-of tech-talk. $72 + 
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
