In der letzten englischen Übung im Modul #ElectricalEngineering ging es um die Wirkleistung, Blindleistung und Scheinleistung sowie die Leistungsfaktorkorrektur einer ohmsch-induktiven Schaltung durch einen Kondensator inklusive der Zahlenrechnung in GNU Octave.

Im gestrigen englischen Plenum des #ElectricalEngineering Moduls ging es um Wirkleistung, Blindleistung und Scheinleistung bzw. die komplexe Leistung, Blindleistungskompensation und Leistungsanpassung in harmonisch erregten linearen Netzwerken, auch mit einem Kahoot-Quiz.

I do miss the SEL 710.
Also I’ll bet this guy has a little glass dish with Worthers Originals candy at his desk. I mean that in a good way of course.

Literally have no one I can talk that electronics nerd shit with irl 😮‍💨 #electronics #fpga #microcontrollers #circuits #electricalengineering

Some people have reverse engineered the UART diagnostic protocol for the BMS of Milwaukee power tool batteries. The video also states that Makita batteries have also had their protocol reverse engineered. This is really useful for hobby projects like robotics where power tool batteries are safe, reliable, high current portable power that can also be used for tools. #ElectricalEngineering #Electronics

Letzte Woche zu dieser Zeit ging es in der englischen Übung #ElectricalEngineering um "Complex Phasors" bzw. das Rechnen mit komplexen Zeigern, das wir uns am Beispiel einer ohmsch-kapazitiven Schaltung angeschaut haben:

I love going through Mouser's new products. Favorite for the day is a 240 nanoamp real-time clock. That's not terribly exciting, except that it's also digitally temperature compensated to +/- 3ppm from -40 to +85C. #ElectricalEngineering #electronics https://www.mouser.com/new/abracon/abracon-ab-rtc-tn-real-time-clocks/

Anschließend haben wir uns in der zugehörigen Übung im Modul #ElectricalEngineering auch noch ein Beispiel zum Superpositionsprinzip sowie zur Leistungsanpassung angeschaut, inklusive eines kleines Experiments mit einer Batterie, einem Labornetzteil und einem Multimeter:

Two different companies make SMARC System on Modules using the MediaTek Genio 700. Yay competition and standards! The power consumption in sleep is 106 mW for the Ezurio board and 265 mW for the SECO. More than double! And there's nothing dramatically different about their capabilities.

I thought the SECO was available in single quantities. The Ezurio is, from Mouser.

The BQ41Z50 pack monitor and fuel gauge is actually available (shockingly) but it is limited to 4 series cells. The big sister chip goes up to a whopping 16 series cells is not available yet, and unfortunately I designed around a 6S pack so I have to wait. The BQ41Z chips (finally) combine pack protection and balancing with a modern fuel gauge algorithm. #battery #ElectricalEngineering https://www.digikey.com/en/products/detail/texas-instruments/BQ41Z50RSNR/26639635

Any #lazyWeb #ElectricalEngineering folks know of an archive of pre-slop-era #circuit designs with annotations somebody could use for learning / hobby fabrication?

I'm looking both for exercises and useful things. Maybe I want to graft an audio interface into an old casio keyboard or z-waveify my air fryer to send push notifications.

Internet search gets me some decent options but about half the time its pinterest or some seo/slop blog stuffed with the diagrams i want but lifted from context. I want the "i want to achieve x" statement too. I want the though process that goes into the choices.

Sometimes theres a "derrived from X" on a diagram but it doesn't say why he dropped these units or added those ...

We have a 40" GE range made in the 1960's. Before that, we had one made in the 1930's. As with our first one, the oven thermostat no longer works and there is no way to replace it (We've made dozens of phone calls across the country. There is most likely one in a junk yard somewhere, but no one has it inventoried).

When we use the oven we play a game of how wide does the door need to be propped open to be at approximately the correct baking temperature.

Die Knotenspannungsanalyse war in der letzten Woche auch das Thema in unserer englischsprachigen Lehrveranstaltung #ElectricalEngineering im internationalen Bachelorstudiengang #EngineeringScience, inklusive eines kleinen Experiments an einer Beispielschaltung.

Außerdem haben wir ein Kahoot-Quiz zum Superpositionsprinzip gemacht.
