Boombox Doorjam Plays Your Theme Song When You Step in the Ring

Although many of us may have had childhood aspirations to be a famous wrestler in the WWE, not very many of us will ever realize those dreams. You can get close, though, if you have your own epic intro music theme that plays anytime you walk into a room. Although it’s not quite the same as entering a wrestling ring, [Matt]’s latest project will have you feeling just as good whenever you enter a room to your own theme song.

The core of the build consists of a boom box with an auxiliary input. The boom box is fed sound via a Raspberry Pi which also serves as the control center for the rest of the project. It runs Node.js and receives commands via websockets from a publicly accessible control server. The Pi is also running Spotify which allows a user to select a theme song, and whenever that user’s iBeacon is within range, the Pi will play that theme song over the stereo.

The project looks like it would be easy to adapt to any other stereo if you’re looking to build your own. Most of the instructions and code you’ll need are available on the project’s website, too. And, if you’re a fan of music playing whenever you open a door of some sort, this unique project is clearly the gold standard. It might even make Stone Cold Steve Austin jealous.

Want To Wake Up In A Ship’s Warp Core? Circadia Sunrise Clock Makes it So

Who among you has difficulty rising in the mornings? Sunrise clocks that simulate a — well, sunrise,  are a gentle means of returning to the waking world. [FlorianH], grappling with this very issue, has built his own impressive sunrise clock he has named Circadia. Some sunrise clocks mate an LED with a dev board and call it a day. This work of hardware art will never be confused for something rudimentary.

Standing at 187cm tall, the 8mm thick PCB frame contains three main sections that plug into each other “like Lego”: the top houses a cleverly designed (and virtually silent) propeller clock and a speaker with a 3D-printed, omni-directional reflector. The midsection is reinforced with an MDF column, around which is wrapped 16 strips of 18 RGB LEDs with a heat-molded sheet of acrylic to diffuse the light, while the bottom section has the mid-woofer, the Raspberry Pi 2 brain, most of the electronics, and three switched power supplies.

Built over two years, the primary feature is a variety of themes — with more being added all the time — ranging from rain forest, to arctic, to the warp core of a starship that will rouse you over the course of a half hour. Circadia can also function as a visualizer during a party, or even a Tetris display (a theme that was designed and tested in an afternoon!). Seeing it in action is a treat:

Barrel organ made from Lego plays the Star Wars theme


Whether or not you are a fan of the first installment of the Star Wars prequels, you have to see what [Lorenz Lnggrtnr] and [Renee Hoffmeister] have put together for the movie’s 3D debut.

In an attempt to capture the essence of Star Wars in a new fashion, they constructed a large barrel organ from Lego bricks that plays the movie’s legendary opening theme when turned. The barrel is separated into four parts, each representing one of the series’ iconic settings in plastic block form.

Hoth, the Death Star, Tatooine, and Endor are all featured on the organ, with each environment’s structures playing specific notes from the song. As the barrel turns each Lego structure toggles a note to be played on the attached organ, via a “reading” mechanism built from metal arms and Lego tires.

It looks fantastic, and sounds pretty decent too. Be sure to stick around for a short video that shows off the barrel organ in action.

Announcing our next theme: Kitchen hacks

Here’s a theme that has the Hackaday staff quite excited; Kitchen hacks. This is a wide-ranging subject that can include anything having to do with food, food preparation, kitchen implements, and enhancements.

We’ve seen quite a few fantastic examples of this theme already. How about a kitchen island the mixes cocktails to order? Perhaps you’d prefer an AI that keeps track of your shopping list or just a computer kiosk that’s nicely integrated. Of course there’s already an iPod dock for that! You might be looking to supe up a pressure cooker, or add a Sous Vide machine to your culinary arsenal. We shouldn’t leave out the ability to ‘print’ images on toast.

Speaking of toast… we’re still waiting for someone to build a laser bread slicer that toasts as it goes. You get the point. Ladies and Gentleman, grab a computer, document your Kitchen hacks, and send them our way!
