Collaborate Disseminate
Fan noise is a contentious issue among the computer community. Some don’t notice it, others rage against it as an annoyance and distraction. Some turn to liquid cooling, while others look to passive solutions to eliminate the scourge. [Matt] of [DIY Perks] may have found a far more oddball solution, …read more

Often, when we think of getting a computer to complete a task, we contemplate creating complex algorithms that take in the relevant inputs and produce the desired behaviour. For some tasks, like navigating a car down a road, the sheer multitude of input data and its relationship to the desired …read more

As far as light fittings go, store bought is fine, but it’s hard to beat something you’ve built yourself from the ground up. [Heliox] demonstrates this well, with a 3D-printed workshop lamp that looks the business and is functional, too.
The lamp has plenty of neat design touches that speak …read more

Just over a fortnight ago, RV Polarstern, a German research vessel, sailed back into port, heralding the end of the largest Arctic research project ever undertaken. The MOSAiC expedition, short for Multidisciplinary drifting Observatory for the Study of Arctic Climate, spent a full year running experiments to measure conditions …read more

Retro gaming enthusiasts have always had great interest in rarities outside the usual commercial titles. Whether they be early betas, review copies, or even near-complete versions of games that never made it to release, these finds can be inordinately valuable. [Modern Vintage Gamer] recently came across a pre-release version of …read more
Electret microphones are capable of high-quality output, and are prized for their smooth frequency response. However, unlike other types, they can’t simply be plugged directly into a mixing desk. Instead, they require special high-impedence circuitry to extract the audio signal for recording. [DJJules] is a big fan of these microphones, …read more
The humble kitchen sink has remained relatively unchanged over the last century. While there are now fancier mixing taps and sleeker fittings available, for most of us, there’s a nozzle that squirts water of varying temperature, and a tub in which to soak dishes. Of course, this leaves plenty of …read more
Time is something uniquely important to humans, and they remain the only creatures on the planet to build devices to regularly track its progress. [Ivan Miranda] is one such creature, and built a giant 7-segment clock for his workshop that really ties the room together.
The clock is a testament …read more

The original Sony PlayStation came out just in time for CD piracy to really start taking off. Aware of this threat to sales, Sony engineers included a copy protection and region locking mechanism that placated executives and annoyed end-users alike. [MattKC] explores how this copy protection worked, and how you …read more
The RC world was changed forever by the development of the lithium-polymer battery. No longer did models have to rely on expensive, complicated combustion engines for good performance. However, batteries still lack the energy density of other fuels, and so flying times can be limited. Aiming to build a drone …read more
