[chbot] Robotics Group meeting, 5 Idris Rd, 630pm, Mon 16 June 2025 report

[Mark Atherton]

Hello everyone,

Good turnout with 28 attendees, and lots of huddles-of tech-talk. $42 + 
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 passed around, and talked about the completed DSP audio engine V2; 
unit has been assembled without issue. An untended via under a couple of 
QFN24/28 packages caused significant assembly issues with V1, along with 
the initial USB/serial device not using the expected CDC protocol.

Rudy talked about and demonstrated AI programming; an extraordinary 
resource.

Andy talked about some interesting 'sources', as well as showing off 
some of his 'detectors'.

Bevin talked about global Cellphone compatibility, and some of the 
associated adventures.

NB 3G is going away soon, send a TXT to 550 and get a report about your 
mobile's capabilities.
