[Oli Wright] is back again with another installation of CRT shenanigans. This time, the target is the humble analog oscilloscope, specifically a Farnell DTV12-14 12 MHz dual-channel unit, which features …read more Continue reading Bust Out That Old Analog Scope For Some Velociraster Fun!
Much of the Earth has been modified by humans, which has a flow-on effect on natural ecosystems, including the insects that carry disease. For the first time, researchers have examined when and how environmental change affects the transmission of insec… Continue reading Increasing human footprint influences spread of insect-borne diseases
We have to admire a YouTube channel with the name [Less Boring Lectures]. After all, he isn’t promising they won’t be boring, just less boring. Actually though, we found quite …read more Continue reading Engineering the Less Boring Way
Playing Asteroids now isn’t quite what it used to be when it came out 40 years ago. At the time, the vector-scan display was part of the charm; making do with an emulator running on a traditional raster display just …read more

Nostalgia aside, there are a few things an analog scope can still do better than a digital, with oscilloscope art being a prime example. The blue-green glow of phosphors in a real CRT just add something special to such builds, …read more

We’ve become used to finding models on websites such as Thingiverse and downloading them to print. After all, whose hackerspace doesn’t have a pile of novelty prints? How about printing them on paper? For the plotter enthusiast that can be particularly annoying. Never fear, [Trammell Hudson] is here with an …read more

We generally cast a skeptical eye at projects that claim some kind of superlative. If you go on about the “World’s Smallest” widget, the chances are pretty good that someone will point to a yet smaller version of the same thing. But in the case of what’s touted as “The …read more

In addition to more than cars that might sell for more than a million dollars, the Monterey Car Week auctions also throw up some remarkable cars that won’t fetch that mark, but are nonetheless, automotive treasures. This article is designed t… Continue reading 50 fascinating cars going to auction in Monterey for less than $1 million
The vintage Macintosh all-in-one computers were a design icon, as well as being highly useful machines in the 80s and 90s. In the decades since, they’ve been used for everything from web servers to aquariums, but that’s not all. [Arcade Jason] decided to grab an old Macintosh Plus and turn …read more
Unlike most old consoles, the Vectrex is unique for having a vector-based display. This gives it a very different look to most of its contemporaries, and necessitated a built-in display, as regular televisions aren’t built to take vector signals. Not one to be limited to the stock screen size, [Arcade Jason] decided the Vectrex needed a projection upgrade, and built exactly that.
The build relies on a lens that [Jason] salvaged from an old rear-projection TV. These units used CRTs with big lenses which projected the image onto a screen. That’s precisely what is happening here, with a vector display …read more
