A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to replicate it using his conventional 3D printer. His attempts to make a joint that changes when submerged in the water looked at several …
If you would like to build the ultimate espresso machine, you might be interested in a new Arduino project for the Gaggiuino. An open-source modification for espresso machines developed by Zer0-bit and a small community of developers and makers. Check out the video below for a short overview of the current base features of the mod which has transformed $500 Gaggia …

Chinese Youtuber [corebb] presents the second version of his POV display. The earlier version used 5050-sized SMT addressable LEDs, which didn’t give great resolution, so he rev’d the design to use a much higher number (160 to be exact) of APA102 LEDs. These are 2mm on the side, making them a little more difficult to handle, so …
An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight is extremely helpful when processing signals digitally, and allows a simpler way to implement frequency-dependent filtration in a digital system. [klafyvel] needed this capability …
For those that don’t know, Gaggia is a company that produces a line of affordable “entry-level” espresso coffee makers that offer good quality consumer espresso machines at reasonable prices. The entry level machines don’t offer fine grained control over temperature, pressure and steam which is where the Gaggiuino project comes in. The Gaggiuino project is an “after …
If you would like to build your very own smart BBQ you might be interested in a new article published to the official Arduino website this week, providing resources and inspiration for home automation projects. Examples include a temperature controlled charcoal smoker, an Alexa BBQ/Kitchen thermometer with IoT Arduino and ePaper display. As well as …

If you’re above a certain age, you probably remember the atmosphere of a pre-Powerpoint 35 mm slide show. The wobbly screen being unrolled, the darkened room, the soft hum of the projector’s fan, the slightly grainy picture on the screen and that unmistakable click-whoosh-clack sound as the projector loaded the next slide. Nowadays you’ll be …

There are plenty of problems that are easy for humans to solve, but are almost impossibly difficult for computers. Even though it seems that with modern computing power being what it is we should be able to solve a lot of these problems, things like identifying objects in images remains fairly difficult. Similarly, identifying specific …
Both Arduino and MicroPython are giants when it comes to the electronics education area, and each one of them represents something you can’t pass up on as an educator. Arduino offers you a broad ecosystem of cheap hardware with a beginner-friendly IDE, helped by forum posts explaining every single problem that you could and will …
The one thing that separates the pros on Twitch from the dilettantes is the production values. It’s all about the smooth transitions, and you’ll never catch the big names fiddling with dodgy software mid-stream. The key to achieving this is by having a streamdeck to help control your setup, like this straightforward design from [Electronoobs]. (Video, embedded …
