A standard early electronics project or kit has for many years been the construction of a small broadcast transmitter with enough power to reach the immediate area, but no further. These days that …

[EvilTim] dug deep into a classic system to finally give the Game Gear a proper video output.  The Game Gear was Sega’s answer to Nintendo’s Gameboy. Rushed to market, the Game Gear reu…

Chess has been around for an awfully long time, automobiles less so. However, there's no reason the two can't be combined, like in this chess set fashioned from automotive components.

The project w...

[Michael Brandl] got to visit the Milka chocolate factory in Bludenz, Austria and was inspired to build this simulation of the production process for the LEGO world 2017 event in Copenhagen.

The pr...

If we cast our minds back to the early years of the transistor, the year that is always quoted is 1947, during which a Bell Labs team developed the first practical germanium point-contact transistor. ...

This good-looking clock appears to be made out of a block of wood with LED digits floating underneath. In reality, it is a block of PLA plastic covered with wood veneer (well, [androkavo] calls it …

Selective Metal Sintering is cool but slow. Fear not, a technology that was initially developed to smooth and pattern laser beams is here to save the day, according to a new paper by Lawrence Livermor...

Ultrasonic repellent devices used to keep away insects, rodents, birds, and even large animals have been around for quite a while, but their effectiveness depends on who you ask.  Some critters just ...

In the world of sailing, there are many records to compete over. Speed records, endurance records, size records. The fastest crossing, the longest solo journey, the largest yacht.

[Sam Kent] and friends built a sound-reactive LED display as part of the Leeds (UK) Digital Festival and exhibited it at Hyde Park Book Club. The installation consists of a grid of 25 tubes, each on...

Apollo astronauts used the DSKY (Display-Keyboard) to interact with the flight computer with a series of 2-digit codes punched into a numeric keypad. Above the keyboard was a high voltage electrolu…

We really don’t know if the world needs it but we’re sure glad [johnnyq90] took the time to build one. We’re talking about a nitro powered rotary tool. Based on a Kyosho GX-12 nit…

The Gameboy line of handheld systems from Nintendo have been wildly popular, but lack one major thing – a video output. This can be troublesome if you’d like to view the games on a bigg…

As multitools have lots of different functions in one case, so [Shadwan's] clock design incorporates a multitude of features. He started the design as a binary clock using a Fibonacci spiral for the s...

When it comes to displays, there is a gap between a traditional microcontroller and a Linux system-on-a-chip (SoC). The SoC that lives in a smartphone will always have enough RAM for a framebuffer …

Google’s voice assistant has been around for a while now and when Amazon released its Alexa API and ported the PaaS Cloud code to the Raspberry Pi 2 it was just a matter of time before everyo…

Hi-Fi hasn’t changed much in decades. OK, we’ll concede that’s something of a controversial statement to make in that of course your home hi-fi has changed immensely over the year…

GSM IMSI catchers preyed on a cryptographic misstep in the GSM protocol. But we have LTE now, why worry? No one has an LTE IMSI catcher, right? Wrong. [Domi] is here with a software-defined base tr…

Sony loves to have control of their own media formats: Beta, DAT, Minidisc, MemoryStick, Universal Media Disc, MemoryStick Micro, and more. When they released the PS Vita they used a format that wa…

We've taken a few microswitches apart, mostly to fix those pesky Logitech mice that develop double-click syndrome, but we've never made a video. Luckily, [Julian] did, and it is worth watching if you...

One of the great strengths of 3D printing is that it makes creating objects with certain geometries much easier than it would be with traditional subtractive machining methods. Things like thin-walle...
