There was a time, 15 years ago, when the € was "strong" and I would buy tons of surplus parts on eBay. That was the great, glorious time, I'd say, and things only got worse from there.It eroded slowly, over a long period : the USD regained its...
I must have watched too many videos of graphical sorting algorithm visualisations. These are hypnotic... I'm so impressed by radix sort and bucket sort, and all the others have a very good lesson in algorithmics to give. But there is always this voice...
So while still waiting for HBSound's Prototyping sponsor, PCBWay, to finish up and ship off the prototypes for that project. I did have some time to work on the ZX81 Restoration. I am still working through the best way to clean...
Hi, I'm Rue Mohr, you might know me from such places as the internet, the information superhighway, or the world wide web. Today I'd like to tell you about an adventure in optimization of a 7 segment decoder. (7 segment display with the highly...
@Paul Gallagher recently did a respin, or should that be a re-ring, of @Ted Yapo 's 20 year old clock project that used a PIC16F84. I thought the original and the tribute were fantastic projects and was curious about the software. As expected it's very...
I built this list, because sometimes I'm bored enough to write the same things again and again, so I have stable place to link. 1) PICs require awkward proprietary tools based on Windows, so you can't use it on Linux or Mac. Nope, see points 2 and 3....
ESP32 The ESP32 development boards are not without their problems. Why keep using them anyway? The ESP32 IC only costs €2.31/pce on Digikey. Design a decent breakout board and done! Well, if you don't want to design your own...
(Updated for Arduino 2 IDE.) As all my friends know, my mugshot is used to illustrate the word lazy in dictionaries. 😉 Anyway I found this AVR MCU in my junkspares box and wanted to test it out. I quickly ascertained that I should install the...
In my previous column, we discussed how everything physical in the universe is made from atoms, which are themselves composed from electrons, protons, and neutrons. Each electron has a single negative (-ve) charge; each proton has a single positive (+ve)...
Who I am and what I do Hey Folks. My name is David Witulla (aka. Gruftgrabbler). I am a student from TU Darmstadt, Germany. Studying "Information- and System Technologie" (aka. Embedded Systems). I just got an amazing offer to build the...
To forestall any questions about how to get the IDE to compile code, Cube is just an IDE, which generates code specific to various STM32 MCU models and dev boards. You have to get a toolchain separately. The ones from the ARM gcc toolchain project are...
Preface A flux capacitor is a fictional device that was created in the award-winning trilogy of films Back to the Future. It is used to power a time travel machine called a DeLorean DMC-12. Flux capacitors are capable of breaking through space-time,...
Understanding the volatile keyword in C and why embedded engineers must know it Okey at any embedded interview you will be asked -What is volatile keyword in C (standart answer)-volatile tells to compiler not to optimize this...
Main Features The Lenkeng LKV372AE extender is considered basic in Lenkeng's lineup. It transmits video with a maximum resolution of 1080p at 60 Hz for a distance of up to 230 feet over a CAT6 cable.It should be noted that the cable category is based...
I'm the owner of a Sunhokey prusa i3 2015 model, and i forgot to talk about it so here is a review of my model. Build volume is 200mm x 200mm x180mm (approximate) arround 15KG and 12v rated.I bought it in kit to assemble for 300$ (including taxes) from...
