Punch Through Switches Gears, Shucks Beans

Do you own a LightBlue Bean or Bean+ from Punch Through? If you don’t have one now, you probably never will, as the company has recently announced they’re no longer selling or supporting the Bluetooth Low Energy microcontrollers. The company says that after selling more than 100,000 Bean devices, the …read more

Everything You Want To Know About The Cheapest Processors Available

Those of us who use microprocessors in our work will be familiar with their cost, whether we are buying one or two for a project or ten million on reels for a production run. We’re used to paying tens of cents or maybe even a dollar for a little microcontroller …read more

Four Years Of Learning ESP8266 Development Went Into This Guide

The ESP8266 is a great processor for a lot of projects needing a small microcontroller and Wi-Fi, all for a reasonable price and in some pretty small form factors. [Simon] used one to build a garage door opener. This project isn’t really about his garage door opener based on a …read more

Hacking The Pocket Operator

The number of easily usable and programmable microcontrollers is small, so when selecting one for a project there are only a handful of very popular, well documented chips that most of us reach for. The same can be said for most small companies selling electronics as well, so if you …read more

Play Tetris on a Transistor Tester, Because Why Not?

[Robson] had been using the same multimeter since he was 15. It wasn’t a typical multimeter, either. He had programmed it to also play the Google Chrome jumping dinosaur game, and also used it as a badge at various conferences. But with all that abuse, the ribbon cable broke and …read more

Low Power Weather Station Blows the Competition Away

Building a weather station isn’t too tall of an order for anyone getting into an electronics project. There are plenty of plans online, and you can even put your station on Weather Underground if it meets certain standards. These usually have access to a reliable source of power, though, and …read more

Making A Three Cent Microcontroller Useful

The Padauk PMS150C is a terrible microcontroller. There are only six pins, there’s only one kiloword of Flash, 64 bytes of RAM, and it doesn’t do multiplication. You can only write code to this chip once, and the IDE uses 8-bit ints. [Anders] got his hands on some of these …read more

Chris Gammell Talks Circuit Toolboxes

Chris Gammell wants to know: What’s in your circuit toolbox?

Personally, mine is somewhat understocked. I do know that in one of my journals, probably from back in the 1980s, I scribbled down a schematic of a voltage multiplier I had just built, with the classic diode and capacitor ladder topology. I probably fed it from a small bell transformer, and I might have gotten a hundred volts or so out of it. I was so proud at the time that I wrote it down for posterity with the note, “I made this today!”

I think the whole point of …read more

Machine Learning on Tiny Platforms Like Raspberry Pi and Arduino

Machine learning is starting to come online in all kinds of arenas lately, and the trend is likely to continue for the forseeable future. What was once only available for operators of supercomputers has found use among anyone with a reasonably powerful desktop computer. The downsizing isn’t stopping there, though, as Microsoft is pushing development of machine learning for embedded systems now.

The Embedded Learning Library (ELL) is a set of tools for allowing Arduinos, Raspberry Pis, and the like to take advantage of machine learning algorithms despite their small size and reduced capability. Microsoft intended this library to be …read more
