  1. [#TRADESHOW] #PCIM #Asia #Shenzhen 2026 will be held from August 26 to 28, 2026, at Shenzhen #World #Exhibition & #Convention #Center. As a leading #power #electronics #trade #fair in #China and the #Asian sister #event of PCIM #Expo & Conference, the exhibition serves as a major #B2B #business #platform for power #semiconductor #technologies, industrial power applications, and next-generation electrification solutions. cnbusinessforum.com/event/pcim

  2. New Video! I use the Amiga to colour the vectors I've created on the CRT and have a lot of fun creating beautiful coloured visuals.

  3. I had some superb luck this week with tubes I bought. I got hold of 5x EF91s for just £5 with shipping, and while two of them are Mullard, the other three are actually Marconi-Osram Valve, made in 1958 and in their original boxes. I'm super happy about that as the Marconi-Osram tubes are rare, and these sound superb in my Little Dots. I actually have well over 20 of these EF91s, most made in 1958 but some spanning up into the 60s before the Hammersmith and Gateshead factories shut down. The ones I have made in 1957 also have heaters that flash brightly on cold-start.

  4. I'm curious if anyone knows where I can easily source these two transistors that appear to now be obsolete - or ideally a modern replacement that fits the same specs?

    C2812
    A1179

    Both are SMD transistors on the #px8 motherboard. I've circled them both in red in the circuit diagram.

    All I find on Digikey are obsolete entries with long lead times and minimum purchases in the thousands.

  5. Our fav Canadian engineer making electric equipment conversions (tractor, outboard motor, snowblower?) LiamTronix is back with his take on an electric boat.

  7. Hello! Finally, I have decided what we shall have for #NakedDieFriday so here goes.

    This is EM9305 by EM Microelectronic, and it's the BLE chip used in the #Lego Smart brick, another interesting chip besides their ASIC which I think I posted about before. Many thanks to the person who sent this sample in, you know who you are!

  8. My latest blog post: Extending CircuitPython with Native Modules - Part 3

    mikecoats.com/extending-circui

    For CircuitPython Day 2026, I wanted to get close to the metal and write a module in C that I could call from CircuitPython. Finally, we bundle everything inside a class.

  9. One thing I find interesting in electronics consultancy is all the various "standards" people have stumbled on for debug UART connectors.

    Ours: 3-pin Molex KK (centre GND, pin1 DUT transmit, pin3 DUT receive). Hate it or love it?

    Common: TRS jack. Inconsistent pinout.

    Common: 2.54mm pitch (dupont) non-polarised (annoying)

    Common: DB9 (DE9… 9 pin dsub, “the rs232 connector”), but they can't decide if they are DTE or DCE, or which gender you're supposed to use for which. have your null modem & gender changer on standby. Also sometimes not even RS-232.

    Semi-Common: Something fucking annoying and weird that is hard to crimp and/or expensive. Ranges from Mini-Fit Jr. to fucking board-mount lemo or fischer.

    Cursed: Micro/Mini USB but it's not USB it's 5V TTL UART seriously why?

    Let me know what you've seen... #electronics

  10. A one-cold decoder from 74HCT00 NAND gates I built this week as an experiment. It is being powered by a single CR2302 lithium cell. These type of circuits are used for address decoding in computer memory, device selection in computer I/O or state machines in embedded systems controllers.

    EDIT: In case you don't know what a "one-cold" decoder is, it is a decoder where one output is logic low instead of logic high: en.wikipedia.org/wiki/One-hot

  11. Process Control Book

    A Resource of Value for Industrial Engineering. Here is an Process Control Online Textbook for learning advanced process control concepts.

    The Reference includes Sample Process Control Course, Instrumentation for Process Control, WEB-Based Educational Resources for Process Control and Process Operability.

  13. Kevin Santo Cappuccio, founder of Architeuthis Flux, joins us to discuss creating Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches.

  15. Ce soir on s'occupe d'un répéteur WiFi pas cher qui fait tourner un petit Linux sur un SoC Mediatek, et ça risque d'être drôle 😅.

    Ça commence dans quelques minutes sur twitch.tv/virtualabs et :peertube: live.virtualabs.fr/w/gr5P6UC18 😊

    For CircuitPython Day 2026, I wanted to get close to the metal and write a module in C that I could call from CircuitPython. This time, we're looking at adding a module-level method.

  17. I liked the way the traces on this old 1GB laptop ram resemble a building. This is a focus stacked image made from 15 images stacked together with different depths of focus.
