We normally meet (but see below) every second Tuesday of the month for talks and demonstrations from 7:00pm onwards at BCB Radio.
Why not come along to a meeting?
Some of us also create IT Stuff for BCB Radio (106.6 FM) every four weeks on Thursday, 6:00pm-6:30pm. Repeated the next day on Friday at 1:30pm-2:00pm.
Darren reported that his DVD drive door opens whenever the machine is returning from sleep; a couple of suggestions were made: that he checks the BIOS firmware and that he checks the boot order to see if the DVD is selected prior to the hard drive.
He is continuing to explore Picroft.
He showed a Bluetooth speaker he had acquired to amplify smartphone audio.
Darren began by sharing what he had been looking at in machine learning and AI: Siri/Alexa/Picroft and a number of personal projects including
As no-one apart from Brian had brought anything to share, the conversation roamed across a range of non-computing topics.
Brian had however solved the problem he had had over booting a Raspberry Pi from a USB drive.
David shared the rather underwhelming photo of BepiColumbo skimming past Venus.
Bernard shared some more of his work for the Astronomy centre, focusing on the Aladin client. One of the problems in astronomy is determining a zero point from which coordinates can be calculated. Traditionally the zero point had been determined as the equinox but it is now determined by using a catalogue of distant objects which are apparently stationary but whose positions can be determined. This has led to a formal definition of the International Celestial Reference System (ICRS) which the Python package astropy will convert by using a website which gives the earth’s position at present.
Brian had been caught in Covid-19 related travel problems and was having to join us using his Raspberry Pi tethered to his smartphone to create an Ethernet connection. He commented that he was able to use iView Australia without any problems.
Brian asked about people’s experience of
get_iplayer and John said that you needed to keep up with the latest version, which Brian had, but John had had no problems with it except when he had not updated it recently.
Brian then expanded on how he had added Node_RED to Home Assistant demonstrating how he could add a gauge by pulling elements from the left hand column. However, he had had difficulty getting Home Assistant to connect to the Internet.
Brian showed a device he had which measures particulates, in particular the PM2.5 particulates which are particularly dangerous. They had recently experienced sand being blown onshore from the Sahara but there had been none of usual cases of people being affected by the sand particles because people were wearing masks because of the pandemic. Bernard said that he had once experienced sand particles on snow when skiing; when snow later fell on the sand, it turned orange.
Brian finally managed to sort out John’s audio by clarifying that in PulseAudio the settings in the Playback and Recording tabs should be 100% and any volume adjustments made in the Output and Input tabs.
As there were still problems with the sound on John’s new laptop, we started with a discussion of sound on chromium, whether it might worth trying Firefox, which did not recognise John’s external microphone, or whether it might be worth trying another microphone, without coming to any satisfactory conclusion.
