If you want to know when the train is coming, you could pull up a webpage on your phone, or walk all the way to the station to look at the displays there. Or, like [eastfamilyreddish], you could build a neat little train info display to decorate your desktop instead. The build is based on […]
Sometimes you need to know what temperature something is, but you don’t quite want to touch it. At times like these, you might want a temp gun on hand to get a good reading, like the one [Arnov Sharma] built. The build is a relatively simple one, and is based around an Waveshare ESP32 C6 […]
[shiura] had a problem — they wanted a nice high-quality audio output for their computer, but they didn’t fancy any of the DACs that were readily available on the market. They specifically wanted one that was affordable, capable, and included a graphic equalizer so they could simply hook it up to a regular amplifier and […]
This week, Hackaday’s Elliot Williams and Kristina Panos met up over coffee to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous seven days or so. On What’s That Sound, Kristina got sort of close, but of course failed spectacularly. Will you fare better and perhaps […]
In the desktop 3D printing world, we’re fortunate to have multiple online repositories of models that anyone can load up on their machine. Looking to create a similar experience but for electronic projects, [Mike Ayles] created CircuitSnips — a searchable database of ready-to-use KiCad schematics available under open source licenses. Looking for reference designs for […]
The Sharp PC-G801 was an impressive little pocket computer when it debuted in 1988. However, in the year 2025, a Z80-compatible machine with just 8 kB of RAM is hardly much to get excited about. [shiura] decided to take one of these old machines and upgrade it into something more modern and useful. The build […]
Rolling two six-sided dice (2d6) gives results from 2 to 12 with a bell curve distribution. Seven being the most common result, two and twelve being the least common. But what if one could do this with a single die? This eleven-sided die has a distribution matching the results of 2d6. As part of research […]
If you’ve got an old black and white TV, it’s probably not useful for much. There are precious few analog broadcasters left in the world and black and white isn’t that fun to watch, anyway. However, with a little work, you could repurpose that old tube as a clock, as [mircemk] demonstrates. The build is […]
When someone creates a US patent, they go through a review process to stop the most blatant copies from previous patents or pre-existing work. After this, you may still have bad patents get through, which can be removed through litigation or publicly accessible methods such as Inter Partes Review (IPR). The latter of which is […]
There’s never been such a thing as being “too competitive” when it comes to competition. This is something that [Tom Stanton] from Tim Stanton (wait, what now), [Tom]’s 2nd channel, took to heart for Polymaker’s 3D design challenge. The goal was simple: a single 3D printed part to hold as much weight as possible. While […]
