via HACKADAY: Custom Split-Flap Display Is a Unique Way to Show the Weather

There’s little doubt about the charms of a split-flap display. Watching a display build up a clear, legible message by flipping cards can be mesmerizing, whether on a retro clock radio from the 70s or as part of a big arrival and departure display at an airport or train station. But a weather station with a […]

via HACKADAY: Vintage Silvertone Cabinet Gets Bluetooth Treatment

This Bluetooth speaker is full of delightful surprises. The outer shell is an antique radio cabinet, but its practically empty interior is a combination of Dead Bug circuitry and modern BT receiver. [PJ Allen] found the BT receiver on Groupon and decided to whip up amplifier and threshold detector circuits using only parts he already […]

via HACKADAY: The History and Physics of Triode Vacuum Tubes

The triode vacuum tube might be nearly obsolete today, but it was a technology critical to making radio practical over 100 years ago. [Kathy] has put together a video that tells the story and explains the physics of the device. The first radio receivers used a device called a Coherer as a detector, relying on two tiny […]

via HACKADAY: Portable Ham Radio Design Fosters Experiments

[Charlie Morris] has been busy building a portable ham radio rig and documenting his progress in a series of videos. You can see the first one below. There’s four parts (more if you count things like part 4 and part 4a as two parts) so far and it is always interesting to see inside a […]

via HACKADAY: Art Deco Radio Gets FM Reception

Taking a vintage radio and cramming it full of modern, Internet-connected, guts has long been a staple of the hacking and making scene. While some might see it as a crime to take what’s arguably a legitimate piece of history and turn it into nothing more than a slipshod case for the Raspberry Pi, we […]

via HACKADAY: Chiptunes on a Solar Panel

With its vintage sound, there’s no mistaking the unique 8-bit sound of video games from the 80s and 90s. It became so popular that eventually sparked its own genre of music known as “chiptune” for which musicians are still composing today. The music has some other qualities though, namely that it’s relatively simple from a […]

via HACKADAY: Speaking the Same Language as a Wireless Thermometer

Temperature is a delicate thing. Our bodies have acclimated to a tight comfort band, so it is no wonder that we want to measure and control it accurately. Plus, heating and cooling are expensive. Measuring a single point in a dwelling may not be enough, especially if there are multiple controlled environments like a terrarium, […]

via HACKADAY: Teardown Of An UWB Location Beacon

Outdoor navigation is a problem that can be considered solved for decades or maybe even centuries, depending on the levels of accuracy, speed and accessibility required. Indoor navigation and location, on the other hand, is a relatively new field and we are still figuring it out. Currently there are at least four competing technologies pushed […]

via HACKADAY: Relive Radio Shack’s Glory Days by Getting Goofy

The Golden Age of Radio Shack was probably sometime in the mid-1970s, a time when you could just pop into the local store and pay 49 cents for the resistors you needed to complete a project. Radio Shack was the place to go for everything from hi-fi systems to CB radios, and for many of […]
