[chbot] Robotics Group meeting, Monday 15 Feb 2021, 6:30pm, 5 Idris Road – Level 2

[Mark Atherton]

Hello everyone,

Good turnout with 23 attendees, and lots of huddles-of tech-talk. $30 + 
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, 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

============

Andrew talked about his new Ender3/V2 3D printer which he loves; the 
overall print quality is excellent. He also demonstrated an 
implementation of the QMK Quantum Mechanical Keyboard, as well as his 
Linux Pine-phone (complete with GUI, and T shirt).

William brought in his Atari 2600 emulator, and continued with his 
presentation about his trailer-lights test unit.

Russell brought along and talked about a roof-mounted fluid/solar 
collector unit, he also talked through some of the related plumbing 
issues. This really has been quite a long journey, and much wisdom has 
been acquired in the process.

Robin talked about his solar-heat surplus, and associated 
melting-plastic-fittings sagas. During summer he needs a significant aux 
heat-dump as the primary (swimming pool) is unusable when it reaches 40C.

Steven continued his discussion relating his AI project, and an 
over-clocked R-PI processor.

Henry talked about salt-baked 3D prints, apparently promoting 
inter-layer adhesion.

Andrew (who helped at the Linux Conf). Brought in and talked about one 
of the event ‘badges’; and ESP-based controller module with a couple of 
O-LED SPI displays and some hidden features.
