[chbot] CHCH Robotics Group, meeting notes 17 April 2017

[Mark Atherton]

Hello everyone,

Reasonable turnout given the weekend holiday. 16 attendees, quite a few 
exhibits, and lots of huddles-of-tech-talk.

$23 collected and transferred to BR05 account. Associated loose change 
is in the Robotics loose-change box.

With thanks on behalf of the group,

Mark Atherton

David Bourke brought in his latest purchase; a third generation Cube 3D 
printer (end of stock, from Noel Leeming). Major issue with the 
unmodified product is the manufacturers cost of filament. Needless to 
say, this limitation has been overcome by David.

Winston brought in his latest, homemade 3D printer. Not quite finished, 
but quite a work of art.

Mark B brought in a whole slew of toys, including an Edison, mounted on 
a daughter-board. Also PiZero W, Raspberry Pi 3, a Micro:bit, a CodeBug, 
and a BeagleBone Wireless.

Darren turned up armed with some interesting items for the trading 
table, including a couple of Apple servers, which caused a great deal of 
interest.

William is making a PCB for his digital watch, and brought along his 
start of schematic capture, and PCB layout. Quite an ambitions first PCB 
project.

Henry talked about the recent Meccano exhibition, at the Great Hall in 
the Arts centre. Exhibits apparently included an auto 
Rubik’s-Cube-Solver, and a Japanese woven-tube-creator.

Robin talked about various insulation issues associated with his home 
made capacitive ground-moisture sensor project.

Darren talked about his home ESP-8266 based sensor network. This 
included discussion of a WiFi network manager. Most interesting project.
