[chbot] Robotics Group meeting, Monday 18 Feb 2019, 6:30pm, 5 Idris Road

[Mark Atherton]

Hello everyone,

Quite a few new faces this evening; welcome.

Enthusiastic turnout with 24 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).

Quick reminder: 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. 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.

With thanks on behalf of the group,

Mark Atherton

William gave us an update on his logic-gate 8-bit computer; main CPU PCB 
is now jumper-wire free. Next step is to continue development of the 
printer interface.

Matthew gave a demo of an SSH server, python, and his own graphics 
library running on his 10 yrs old Kindle.

Volker talked about his temperature sensor woes after installing a TO-92 
single wire sensor mounted out-doors.
