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 […]
Prototyping is a personal affair, with approaches ranging from dead-bug parts on tinplate through stripboard and protoboard, to solderless breadboards and more. Whichever you prefer, a common problem is that they don’t offer much in the way of solid connections to the outside world. You could use break-out boards, or you could do like [Pakequis] […]
Detecting single photons can be seen as the backbone of cutting-edge applications like LiDAR, medical imaging, and secure optical communication. Miss one, and critical information could be lost forever. That’s where FPGA-based instrumentation comes in, delivering picosecond-level precision with zero dead time. If you are intrigued, consider sitting in on the 1-hour webinar that [Dr. […]
