This 3 minute video shows how to connect a $2.00 USB to UART adapter to a serial port on some things like cameras, modems, etc. You need three short Dupont connector cables, green for ground and transmit and receive (crossover). Connect the adapter to the USB port on your PC. Then in Linux open a

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

“”The 5 cent microcontroller! Got myself 100 Padauk PMS154C, one time programmable microcontroller. 2K program memory, 128 bytes of RAM, 6 timers (some 8 & 11 bit pwm capable), hardware comparator, deep sleep and interrupts capable. Alongside the proprietary programmer too (about 100$). Perfect to flash a few leds on toys, or similar simple cheap

Sam the Electric Viking tells us in this 9 min. YouTube video. Tony Seba (RethinkX) predicted EV battery prices would fall 50% by 2027. It now looks like it may happen this year. Last year they reduced prices by 30%. This is important because 35 to 40% of the cost of the EV is the

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

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.
For more than a year during this ‘chip shortage, I’ve constantly heard, Elon Musk should build a chip fab. Build a chip fab! Build a chip Fab! Over and over again. It turns out that the chip shortage is actually a wafer shortage – there are not enough 200 mm (8 inch) wafers to make

Rob Maurer’s Tesla Daily episode https://youtu.be/m8TMPbUgpBU About car makers in general, Rob said, “These companies want things to stay the same. They want to take the path of least resistance, and that is continuity. … Those results are visible now as these companies work through the chip shortage.” Tesla is faced with the same logistics

Tesla has developed a workaround for the microcontroller chip shortage. They developed 19 variations of controllers by changing the hardware and software. You can read the text of the video in the description. https://youtu.be/B8b73Zsnn5A
From FB comment Monty Ross It’s true that optocouplers are used for isolation. But I have seen whole sections of PC boards with a hole burned where the optocouplers used to be. It is incredible how much damage the power lines do to the PC boards due to high voltage spikes in the power. Transformers
