Meeting proceedings for Friday 14th of February 2020

Wayne Sierke presented several versions of flyers he had been working on. He explained that this was a work in progress and invited contributions.

David Zerk passed around our new microphones and wireless mike which comply with Australian Frequency Standards. David brought in a mixing console and demonstrated how it could be used.  After some discussion it was determined that a smaller unit should be acquired for club use.  John O’Sullivan offered to see if some of his loud speaker and amplifier kits cold be resurrected for use at meetings. David moved that several associated items be investigated and this was seconded by Rick Matthews.

Peter Gheude gave a brief demonstration of an ESP-12F Wi-Fi module with ESP8266basic installed.  Several members were interested and promised more on how to interface a TFT touch display at next meeting.  James was interested in how to program the ESP series using a Mac which could be done at the next meeting.

There were insufficient members present for the 2020 AGM as the number of members present for a quorum was short by 2 members.  The Group’s Constitution requires at least 10 members so the AGM was deferred until next meeting.

Cliff asked if anyone would nominate a member for any of the executive and office positions as he would not stand for the Chairman or other role.

Peter Gheude agreed to remain as Secretary/Treasurer.  
Wayne Sierke indicated that he would stand if nominated as Chairman.   
Chris Burrows in his letter of apology for being absent from this and the following meeting offered to stand for the WEA representative.  
Rick Matthews also wished to stand for this position.  
Wayne offered to continue as the Website editor.  
Committee – Colin, Chris, John and David.

The minutes for this meeting are available here.
