At the recent 38C3 conference in Germany, someone gave a talk about sending TOSLINK digital audio over fiber optic networks rather than the very low-end short distance fibre you’ll find behind hour CD player. This gave [Manawyrm] some ideas, so of course the IP-over TOSLINK network was born. TOSLINK is in effect I2S digital audio […]
Every engineer is going to have a bad day, but only an unlucky few will have a day so bad that it registers on a seismometer. We’ve always had a morbid fascination with engineering mega-failures, few of which escape our attention. But we’d never heard of the Super-Kamiokande neutrino detector implosion until stumbling upon [Alexander […]
It is old news that you can print PCB artwork on glossy paper and use a clothes iron to transfer the toner to a copper board, which will resist etchant. But [Squalius] shows us how to do a similar trick with 3D prints in a recent video, which you can see below. The example used […]
For a lot of us, soldering just seems to come naturally. But if we’re being honest, none of us was born with a soldering iron in our hand — ouch! — and if we’re good at soldering now, it’s only thanks to good habits and long practice. But what if you’re a company that lives […]
Much has been written about the demise of physical media. Long considered the measure of technological progress in audiovisual and computing fields, the 2000s saw this metric seemingly rendered obsolete by the rise of online audiovisual and software distribution services. This has brought us to a period in time where the very idea of buying […]
Nobody likes reading the fine print, least of all when you’re just downloading some 3D model. While printing a copy for personal use this is rarely an issue, things can get a lot more complicated when you make and distribute a derived version of a particular model. Case in the point the ever popular 3DBenchy […]
There are many ways to build a radio receiver, but most have a few things in common, such as oscillators, tuned circuits, detectors, mixers, and amplifiers. Put those together in the right order and you’ve got a receiver ready to tune in whatever you want to listen to. But if you don’t really care about […]
Many of us used “big iron” back in the day. Computers like the IBM S/360 or 3090 are hard to find, transport, and operate, so you don’t see many retrocomputer enthusiasts with an S/370 in their garages. We’ve known for a while that the Hercules emulators would let you run virtual copies of these old […]
