2023-08-18 Ferroelectric Memory Transistor Demonstrated
Several decades ago I read about these new Josephson devices that the scientists had invented, and how they would do wonderful things in the future. Here we are decades later and we hear nothing about Josephson devices. So here’s another interesting device, it uses indium selenide. It sounds promising but it may end up like

2023-08-12 Moore’s Law Is Dead? – Sabine
Sabine Hossenfelder goes over the history and ways that Moore’s Law may still make progress. Also a few good comments.
2023-08-10 MEMS Accelerometer Micro Photo
Amazing how tiny the pieces are. The photo was taken with an electron microscope. More about MEMS accelerometers here: https://mems.polimi.it/index.php/accelerometers?fbclid=IwAR2riO6QcedkMZXuZJCsXvM2evY9m_Dv8fbpsf7GwjQdw8dL_NyYaVugmYo
2023-08-07 Auto ECM Electronic Repair – A New Business Opportunity
This is a quote from a post in a group about auto ECM – electronic control module – repair. “”Andrew Brown 12h To the young budding electronics techs out there – listen up. This is a potential opportunity for you to build a decent business with pretty dedicated customers. (No involvement on my part.) The

2023-07-07 Tesla Sudden Acceleration Due To Voltage Spikes
This could affect all models. The heavy power could have caused a negative voltage spike that mimics a pressed accelerator. https://www.notebookcheck.net/Sudden-Tesla-acceleration-attributed-to-voltage-spikes-that-may-have-tricked-NHTSA-into-ruling-it-driver-error.732407.0.html
2023-06-27 The Reasons Behind The Chip Shortage (Sabine)
Very good video about the chip shortage. There were fires in several plants, natural disasters like the earthquake in Fukushima, and too much dependence on only a few factories. We need to prevent this from happening again.
2022-06-01 USB Cable Internal Resistance
I had a “high quality” 1 meter long USB A male to type C charging cable go bad so I cut the bad type C connector off. Then I stripped and twisted the two 5V wires together and measured the total wire resistance on the A end with my HP 3478 DMM in the 4
