We had a really positive and energetic session on Wednesday (2020-01-29) which was once again an experimental early start. Ten people I think - unless I missed someone! Some introductions were in order as not everyone had already met.
As Will was away, three or four of us tried to follow the instructions to bring up our local Pi-based data collection server, with only partial success. But we felt we’d learnt something, and no doubt the exercise will help us improve the documentation. We did get an air quality sensor working, on the LAN, taking measurements, and it was contacting the server, but was not succeeding in getting the database updated.
Paul brought in a nicely aged Amstrad PC, with two floppy disk drives for different disk sizes: the later hard shell 3½ inch and the earlier actually-floppy 5¼ inch. This is a machine he uses to rescue or copy older floppies that people discover, but it has developed a hardware fault. We might look at this in a later session. (This model of PC dates from 1986. But still not the oldest computer we’ve had at a session!)
Danny posted a video which shows an experiment with Arduino and a couple of infrared proximity sensors:
There was certainly some activity with the two in-service 3D printers (not both ours) but I’m not sure what. I did accidentally unplug one of them but it turned out to be idle at the time.
Danny has been buying some bits, as we gain experience in what’s needed, and so there was a bit of plugging things together to make sure everything works as it should: we got a new HDMI screen for a Pi, so we have a cheap and cheerful computer setup if we need one. There are still some odds and ends to be bought.
