A great many PlayStation 2 games were coded in C++, and there are homebrew SDKs that let you work in C. However, precious little software for the platform was ever created in Golang. [Ricardo] decided this wouldn’t do, and set about making the language work with Sony’s best-selling console of all time.  Why program a […]
A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or capability of what’s on the commercial market. [Chris] from Zoid Technology recently found a portable spectrometer complete […]
[Luca Dentella] recently encountered a toy, which was programmed to read different stories aloud based on the figurine placed on top. It inspired him to build an audio device using the same concept, only with music instead of children’s stories. The NFC Music Player very much does what it says on the tin. Present it […]
[Jamie] decided to build a generator, and Lego is his medium of choice. Thus was created a fancy levitating generator that turns a stream of air into electricity.  The basic concept is simple enough for a generator—magnets moving past coils to generate electricity. Of course, Lego doesn’t offer high-strength magnetic components or copper coils, so […]
Hackers like making clocks, and we like reporting on them around these parts. Particularly if they’ve got a creative mechanism that we haven’t seen before. This fine timepiece from [gooikerjh] fits the bill precisely—it’s a sliding tile clock! The brains of the build is an Arduino Nano ESP32. No, that’s not a typo. It’s basically […]
When you think of printing on paper, you probably think of an ink jet or a laser printer. If you happen to think of a thermal printer, we bet you think of something like a receipt printer: fast and monochrome. But in the last few decades, there’s been a family of niche printers designed to […]
Let’s say you had a SNES with a busted CPU. What would you do? Your SNES would be through! That is, unless, you had a replacement based on an FPGA. [leonllr] has been developing just such a thing. The project was spawned out of necessity. [leonllr] had purchased a SNES which was struck down with […]
Are you eager to get your feet wet in the keyboard surf, but not quite ready to stand up and ride the waves of designing a full-size board? You should paddle out with a macro pad instead, and take on the foam face-first and lying down. Image by [Robert Feranec] via Hackaday.IO Luckily, you have […]
We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment in making a DIY reduced noise, gearless actuator and you can see the result here. Here’s how it works: the […]
We are always fascinated by bubble memory. In the late 1970s, this was the “Next Big Thing” that, as you may have guessed, was, in fact, not the next big thing at all. But there were a number of products that used it as non-volatile memory at a time when the alternative was tape or […]
