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 […]

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

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

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

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

Many of us have been asking for some time now “where are our robot servants?” We were promised this dream life of leisure and luxury, but we’re still waiting. Modern life is a very wasteful one, with items delivered to our doors with the click of a mouse, but the disposal of the packaging is
THIS IS THE FUTURE OF WASTE MANAGEMENT Continue Reading
The official Arduino development team has this week announced a new enterprise service in the form of the Arduino Cloud for Business. Offering unique benefits for companies and industrial clients looking for ways to utilise enhanced features in terms of device management, fleet management, secure and safe remote access and RBAC to name a few. The new Arduino

Makers and electronic enthusiasts creating projects with ePaper displays might be interested in a new Kickstarter campaign launched this week for EnkPi. A range of ePaper displays powered by the awesome Raspberry Pi Pico W mini PC. Available in a range of different sizes the open source displays have been created by a small team of

Most modern computer games have a clearly-defined end, but many classics like Pac-man and Duck Hunt can go on indefinitely, limited only by technical constraints such as memory size. One would think that the classic electronic memory game Simon should fall into that category too, but with most humans struggling even to reach level 20 it’s hard to be sure. [Michael
