Peter Harris brought in a pile of his surplus grid-tied-invertors, along 
with some stories associated with similar, newer product he has 
purchased. Quite a technology shift noted with the five years between 
the two technologies; mainly in exposed features.

William discussed his latest electric-watch, complete with I2C connected 
smart-LION battery monitoring.

Robin talked about some the issues associated with switching/sharing a 
DC solar source with open circuit potential of 500V, and continuous 
currents of 10A. Interesting problem.

Mark briefly talked about the youtube video ‘humans need not apply’, 
along with other implications of some rapidly approaching technological 
changes. Also briefly touched on ‘Universal Basic Income’, and some of 
the implications.

Volker discussed display contrast enhancement by the use of colour 
filters, and followed up on some of the recent email discussions. Also 
demonstrated a high temperature insect sting neutraliser, for direct 
application to the epidermis. Cries of 'ouch' rang out as the device was 
tested by the unwitting audience !

David Bouke, talked about his experience repairing product with 
bond-wires, and chip-on-ceramic technologies. Latest investigations 
include a home-made ultrasonic wire-bonder.
