Enthusiastic turnout, with 22 attendees and $22 collected and
transferred to BR05 account. Balance is in the donation box.
New members: Sean, and Shaune.
With thanks on behalf of the group,
Brindsley brought in a low cost pick and place machine, along with IR
reflow oven. Huge amount of interest. Since borrowing the equipment, it
had quite a few unexpected issues that needed to be understood
(including some subtle component orientation puzzles).
Mark B brought in several WiFi controlled mains lights, and in-line
power controllers which were discussed last meeting. He is planning to
create a quick-start guide for MQTT/Node-Red integration.
Mark A talked about remote management of the radio club Heat Pumps. Main
issues revolved about distribution of the Infra Red control signals, and
associated opportunity for feature creep.
Volker talked about trials and tribulations with 18650 LiOn cells, and
size differences with/without protection. Discussion moved on and
included various low cost display technologies, and laser cut Arduino cases.
William reported on his watch/clock project, now with accelerometer.
Andy demonstrated the latest item in his HP equipment museum; an HP
5036A Microprocessor Lab, in pristine condition, complete with full
manual, and attaché case (Mr Bond...)
Robin report that his high power invertor project is proceeding nicely;
he plans to do a demo next meeting.
