[chbot] Robotics Group meeting, 5 Idris Rd, 6-30pm, Robotics 17 Oct 2022

[Mark Atherton]

Hello everyone,

Good turnout with 20 attendees, and lots of huddles-of tech-talk. $27 + 
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 some items of interest, including a small 100 Henry 
inductor - add 1uF for a 15Hz tuned circuit (!), also a small Deuterium 
Arc Lamp.

Mark talked about a PCB layout issue with the Digital Video Decoder 
project. A PCB footprint appeared to have been cached from a previous 
design. This was of course the only wrong footprint in the whole library!

William talked about his latest incarnation of the clock/thermometer 
project. Updates include auto-brightness, and blinking colons.

Robin talked about his latest design for the window-openers in his 
greenhouse(s), and associated automation system.

Michael talked about his home automation system that is based on Home 
Assistant, and ESP Home. He also discussed progress with his home-made 
furnace.
