You might have had a boombox back in the 1990s, but probably not like the Yamaha MDP-10. As [Nicole] explains, the odd little device played MIDI files from a floppy disk. Technically, it wasn’t truly a boombox because it lacked batteries, but it sure looks like one. The box also had a MIDI input jack, but no output. For an antique gadget, it is pretty...

Helicopters are perhaps at their coolest when they’re being used as flying cranes — from a long dangling cable, they can carry everything from cars, to crates, to giant hanging saws. What you might find altogether more curious are the helicopters that fly around carrying gigantic flat antenna arrays. When you spot one in the field, it’s not exactly...

Over the past few years a number of teams have been putting a lot of effort into taking beloved Nintendo 64 games, decompiling them, and lovingly crafting them into highly portable C code. This allows for these games to not only run natively on PCs, but also for improvements to be made to the rendering engine and other components. Yet this artisan...

His earlier vehicle designs were great educational fun, but were limited to about a kilowatt of power. His current platform is in theory capable of about twenty. The last big change he made was...

[Markus] grabbed an ESP32 and created a good-looking e-ink dashboard that can act as a status display for Home Automation. However, the hardware is generic enough that it could work as a weather station or even a task scheduler. The project makes good use of modules, so there isn’t much to build. A Waveshare 2.9-inch e-ink panel and an ESP32, along...

Stringing a badminton racquet is a somewhat complicated job. It needs to be done well if the racquet is to perform well and the player is to succeed. To that end, [kuokuo] built a machine of their own to do that very task. Even better, they’ve made it open source so other hobbyists can benefit from their work. The build is named PicoBETH, which stands...
