Hi, Mike's Electric Stuff: Lots of interesting poking about bits of electrical equipment from Mike Harrison, who some may know from the Acorn Archimedes where he designed things like the video digitiser ‘podule’ sold by Watford Electronics. http://www.electricstuff.co.uk
He has a YouTube channel too, linked from there, which includes things like a tear-down of a Roche 454 GS FLX+ DNA genome sequencer. https://www.youtube.com/watch?v=XaumUp4GpCw And he still makes and sells boards and products at http://www.whitewing.co.uk, e.g. his Etherdecode which turns a 100 Mbit/s Ethernet signal into parallel signals for a logic analyser. He's thinking of doing a USB equivalent. Fear, uncertainty, and doubt: The tactic has widely been used by Microsoft Corporation against Linux operating systems since the 1990s. https://en.wikipedia.org/wiki/Fear,_uncertainty,_and_doubt Social media censors science: ‘Kulldorff, Heneghan and Jefferson are not snarling conspiracy theorists or bluffers wading into things they don’t understand. They are dissenting scientists and medics who hold positions at esteemed institutions. On what basis could Facebook or Twitter simply declare their arguments null and void?’ https://www.spectator.co.uk/article/covid-has-emboldened-our-modern-censors/amp Retired NHS pathologist Dr John Lee criticises the Government's response to the pandemic, analyses why proven scientific procedures were abandoned, makes the case for ending Lockdown now, highlights the cancelling of critical scientific debate, etc. Google originally took the video off YouTube but had to reinstate its heresy. https://www.youtube.com/watch?v=spmPax0rq5A ‘John Andre Lee (born 1961) is a retired English pathologist who was formerly clinical professor of pathology at Hull York Medical School and consultant histopathologist at Rotherham General Hospital, later becoming the Rotherham NHS Foundation Trust's Director of Cancer Services.’ ― https://en.wikipedia.org/wiki/John_Lee_(pathologist) ‘He gained a PhD in pathophysiology and is a Fellow of Royal College of Pathologists and of the Institute of Biology... He wrote a monthly column for The Lancet Oncology for 5 years. Among many other roles, he has served as Director of Publications for the Royal College of Pathologists, a member of Council of the Physiological Society, Chairman of the Editorial Board of Biologist, and on the Editorial Board of Physiology News.’ ― https://humanism.org.uk/about/our-people/patrons/professor-john-a-lee/ UK domain holders pay Nominet through registrars, many of which aren't happy by the board actions over the past few years and they've been trying to oust the board after their concerns were ignored. https://en.wikipedia.org/wiki/Nominet_UK#Controversy https://www.theregister.com/Tag/nominet And this one was from IRC the morning after the meeting... A board which turns a Raspberry Pi Compute Module 4 into a mini-ITX ‘motherboard’ suitable for a normal case. Of particular interest is exposing the module's PCIe which isn't available on the stock Pi 4. The status updates mention an M.2 NVMe socket is being added as one of the ways to use it, e.g. for SSD storage. https://www.indiegogo.com/projects/over-board-raspberry-pi-4-mini-itx-motherboard#/ There's quite a few boards being made to host the Compute Module 4, e.g. one with four SATA ports IIRC. For those who don't know, the CM4 comes in 32 varieties. 2 Wi-Fi or not × 4 RAM: 1/2/4/8 GiB × 4 Storage: SD card/eMMC 8/16/32 GiB https://www.raspberrypi.org/products/compute-module-4/ Here's another two projects which make use of the PCIe on the CM which is not available on the Pi 4. - Four SATA connectors on PCIe. Handy for a home NAS. https://www.crowdsupply.com/wiretrustee/wiretrustee-sata - A board with gives the normal connections to a Compute Module 4 but with PCIe too. Could be used for a single PCIe SSD. Unfortunately, they've dropped the Ethernet connector, stopping it being a nice home PC. https://www.crowdsupply.com/diodes-delight/piunora -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2021-06-01 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
