Have you got a USB disk drive or flash drive that was sold at a price so low it was “too good to be true”? Steve Gibson’s Validrive will do spot checks to see if the SSD or flash drive is really what it claims to be. Fake drives are sold for cheap and the

A 5 min. YouTube video. Sam the Electric Viking said that the supercomputer is now in New York. There will be a new AI data center (being built) in Gigafactory Texas.
I’ve probably already blogged this, but it deserves to be reprised because it is so important. Tony Seba and RethinkX made this prediction in this report, dated 2017, available at the link below. It’s been seven years since this report was released and recently there has been large incremental improvements in the autonomous self-driving systems.

The modules use both the RCWL-9616 and the BISS-0001 but it seems the schematics are all labeled BISS-0001. The parts values are different. He gives some good information about them. They operate at 3.5 and 3.98 GHz – the ones I have were advertised at 5 GHz. Also he shows his own version that uses a

Supposed to have 10 to 14 km range. But probably at very low data rates. https://www.facebook.com/reel/936216961243959?mibextid=9drbnH&s=yWDuG2&fs=e
A long time ago when we were going to Cat5 UTP, I had a lot of these MX20Ts left over. So I made up a 15 pin plug with the negative 9VDC on pin 6 and positive on pin 13, and soldered the wires to the battery contacts. I taped the battery to the back

In the “Original Series” chapter this very interesting Wikipedia article talks about the “hearing aid computer” that used the OC-71 germanium transistors which were used in hearing aids and could go only up to 25kHz clock rate. That was quite slow – tube computers could clock at 500kHz. Later models used faster transistors and could

This very comprehensive electronics website has many projects with useful devices. This example project is a transistor curve tracer. Go to the index and look at the many, many links. It seems to be at the ETH in Switzerland but some of the words are in ?Thai? https://www.changpuak.ch/electronics/Curve_Tracer_advanced.php#
