Collaborate Disseminate
Before smartphones and Internet of Things devices were widely distributed, the Automatic Packet Reporting System (APRS) was the way to send digital information out wirelessly from remote locations. In use …read more Continue reading APRS Implemented at Low Cost and Small Size
While Mazda has made some incredible advances in fuel efficient gasoline engines over the past few years, their design group seems to have fallen asleep at the wheel in the …read more Continue reading Custom Keyfob Fixes Mazda Design Mistake
Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if …read more
The Mandelbrot set is a curious mathematical oddity that, while interesting in its own right, is also a useful tool for benchmarking various types of computers. Its constant computing requirement when zooming in and out on the function, combined with the fact that it can be zoomed indefinitely, means that …read more

Moore’s law may have reached its physical limit for transistor density, but plenty of other technologies are still on that familiar path of getting smaller and smaller as time passes. It looks like LIDAR is no exception to this trend either. This project from [Owen] shows a fully-functional LIDAR system …read more
The ESP32 was introduced a few years ago as an inexpensive way to outfit various microcontrollers with WiFi or Bluetooth. Since then it has been experimented with and developed on, thanks to its similarities to the ESP8266 and the ability to easily program it. Watching the development of this small …read more
We’ve reported on the world of electronic badges here at Hackaday since their earliest origins in [Joe Grand]’s work for DEF CON 14 in 2006. In that time we’ve seen an astonishing variety of creations, covering everything from abstract artwork to pure functionality in a wearable device. But it’s not …read more
You’ve got to admire the steps some people take to squeeze a shop into a small space. Finding ways to pack in ever more tools and to work on bigger and bigger projects become ends to themselves for some, and the neat little tricks they find to do so can …read more

When building projects with a simple goal in mind, it’s not unheard of for us to add more and more switches, buttons, and complexity as the project goes through its initial prototyping stages. Feature creep like this tends to result in a tangled mess rather than a usable project. With enough focus, though, it’s possible to recognize when it’s happening and keep to the original plans. On the other hand, this single-button project with more than one use seems to be the opposite of feature creep. (YouTube, embedded below.)
[Danko]’s project has one goal: be as useful as possible while …read more
