For next month's meeting on the 19th, I have asked Vince Hudd if he would like to come along and do a demonstration. I'm sure you're aware that he has written some software, but he is also in the process of creating his own Raspberry Pi case. It's been so long since our last guest speaker that I can't remember what we've done in the past. Any thoughts Graham? Mark. Visit the WAUG website //www.freelists.org/webpage/waug
