As single board computers have become ever smaller and more powerful, so have those experimenting with them tried to push the boundaries of the machines they can be used in. First we had cyberdecks, and now we have handheld terminals. Of this latter class we have a particularly nice example from [Random Alley Cat]. It […]
For those of a certain age the first digital camera many of us experienced was the Game Boy Camera, an add-on for the original Game Boy console. Although it only took pictures with the limited 4-tone monochrome graphics of this system, its capability of being able to take a picture, edit it, create drawings, and […]
Home routers and cable modems are now extremely powerful devices, but they all suffer from the attention of their manufacturers’ design and marketing departments. Instead of neatly packaging them in functional cases, they impose aesthetics and corporate identity on them, usually resulting in a curvy plastic case that’s difficult to integrate with other network infrastructure. […]
As hardware ages, it becomes harder and harder to keep it in service. Whether that’s because of physical aging or lack of support from the company who built it in the first place, time is not generally good for electronics, especially when it comes to our beloved retro gaming systems. The first Playstation, for example, […]
You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow clock. The heart of the build is an ESP8266 microcontroller, which gets the current time via Wi-Fi by querying an NTP time […]
It’s hard to argue that Soviet-Era nuclear engineering may have some small flaws, what with the heavily-monitored exclusion zone around Chernobyl No.4. Evidently, their industrial designers were more on-the-ball, because [Alex] has crafted the absolute most stylish fallout monitor we’ve ever seen, with ESP32 and a vintage Soviet-designed plasma display to indicate radiation levels in […]
Laser-engraving a cylindrical object usually requires a rotary attachment, which is a motorized holder that rotates a cylindrical object in sync with the engraver. But [Samcraft] shows that engraving all around a mug can be done without a motorized rotary holder. Separating a design into elements thin enough to engrave individually without losing focus is […]
Just about every electronic device has some silicon semiconductors inside these days—from transistors to diodes to integrated circuits. [Charles] is trying to build a “No-Silicon digital clock” that used none of these parts. It looks like [Charles] is on the way to success, but one might like to point out an amusing technicality. Let’s dive […]
