Jukebox Gets Raspberry Pi Update, but It’s Not for Streaming

Here’s a retro-electronic rehab with a twist. Normally we’d expect a jukebox Raspberry Pi project to replace the obsolete electromechanical guts with streamed music, but an intact jukebox with a Raspberry Pi remote control is a nice change.

Old-time jukes like [revnhoj]’s 1954 AMI F120 are electromechanical marvels. Stocked with 60 45-rpm discs in a horizontal rack, an arm mounted on a track would retrieve the correct disc and place it on the turntable to play the selected song. The unit in the video below was the main jukebox, which supported “wall boxes” mounted at booths so patrons could select tunes without leaving their tables. [revnhoj] simulated a wall box with a Raspberry Pi connected to the original wall box interface through relays. The Pi serves up a GUI that can be accessed via a tablet, the correct contacts are tickled, and [revnhoj]’s collection of 45s is played through the original mechanism and amplifier, in all its “Sonoramic Sound” majesty. It’s a pretty neat hack that adds new functionality while being true to the original platform.

The chatter on the reddit thread where we spotted this hack was trending toward adding streaming audio, but we truly hope the juke stays intact and serving only vinyl. We’ve seen jukeboxes gutted before, and while it might make sense for some, we like the old school approach better.

Payphone Boombox Straight Out of the 1990’s.

Due largely to the overwhelming dominance of mobile phones, payphones are a sometimes overlooked relic from the 90’s and earlier eras. While seldom seen out in the wild these days, they can however still be acquired for a moderate fee — how many of you knew that? Setting out to prove the lasting usefulness of the payphone, Instructables user [Fuzzy-Wobble] has dialed the retro spirit way past eleven to his ’90 from the ’90s’ payphone boombox.

Conspicuously mounted in the corner of his office, a rangefinder sets the phone to ringing when somebody walks by — a fantastic trap for luring the curious into a nostalgia trip. Anyone who picks up will be prompted to punch in a code from the attached mini-phone book and those who do will be treated to one of ninety hits from — well —  the 1990’s. All of the songs have been specifically downgraded to 128kbps for that authentic 90’s sound — complete with audio artifacts. There’s even a little easter egg wherein hitting the coin-return lever triggers the payphone to shout “Get a job!”

Levitating Table Makes the Sound of This Holochess Jukebox

A bubbling Wurlitzer juke would be a prized addition to the classic picture of a man cave — brass-railed bar, kegerator, pool table, tin signs and neon on the walls. But it would take a particularly geeky abode to give a proper home to this Millenium Falcon holochess table jukebox. And a particularly awesome one at that.

dsc02100It all started with a very detailed and realistic replica of a holochess table made by [Jim Shima]’s friend. A lot of time and care went into the prop, and [Jim] was determined not to alter the look while installing the media player gear, consisting of a Raspberry Pi running OSMC and a 160-watt power amp.

The speakers were problematic – there was nowhere convenient to mount them except under the brushed aluminum playing surface of the table. The sound quality was less than acceptable, so rather than poke unsightly holes in the table, [Jim] devised a servo to lift the table while the music is playing.

An LCD monitor and wireless keyboard slightly detract from the overall look; we’ll give [Jim] a pass until he can come up with a holographic display to finish the build right. But we are disappointed that he didn’t use “Mad About Me” by Figrin D’an and the Modal Nodes as the demo tune in the video below.

It’s a nice build, and you’ll want to check out [Jim]’s Hyperdyne Labs for more drool-worthy props and effects. And for another fandom jukebox, look over this jukebox that’s bigger on the inside.

Toddler Jukebox Requires No Quarters or Button Mashing

Ahh, toddlers. They’re as ham-fisted as they are curious. It’s difficult to have to say no when they want to touch and engage with the things that we love and want them to play with. [Shawn] feels this way about his son’s interest in the family Sonos system and engineered an elegant solution he calls Song Blocks.

The Sonos sits on a dresser that hides a RasPi B+. Using bare walnut blocks numbered 1-12, his son can use the Sonos without actually touching it. Each block has a magnet and an NFC tag. When his son sticks a block on the face of the right drawer containing embedded magnets and an NFC controller board, the B+ reads the tag and plays the song. It also tweets the song selection and artist.

The blocks themselves are quite beautiful. [Shawn] numbered them with what look like Courier New stamps and then burned the numbers in with a soldering iron. His Python script is on the git, and he has links to the libraries used on his build page. The Song Blocks demo video is waiting for you after the jump.

The Most Beautiful Floppy Disk Jukebox Ever

Playing music on floppy drives is something that has been done to death. [kiu]’s RumbleRail is something else entirely. Yes, it’s still a collection of floppy drives playing MIDI files, but the engineering and build quality that went into this build puts it in a class by itself.

Instead of the usual assemblage of wires, power cords, and circuits that accompany most musical floppy drive builds, [kiu]’s is an exercise in precision and modularity. Each of the eight floppy drives are connected to its own driver with an ATMega16 microcontroller on board. The microcontrollers in these driver boards receive orders from the command board over an I2C bus. Since everything on the RumbleRail is modular, and the fact [kiu] is using DIP switches to set the I2C address of each board, this build could theoretically be expanded to 127 voices, or 127 individual floppy drives each playing their part of a MIDI file.

The RumbleRail can also operate in a standalone mode without the need for a separate computer feeding it data. MIDI files can be loaded off an SD card by the main controller board, and decode them for the floppy drivers.

If you’d like to build your own RumbleRail, all the board files, schematics, and firmware are up on [kiu]’s git. There are, of course, a few videos below of the floppy jukebox in action.

Arduino MP3 Jukebox

Here’s an inexpensive Arduino-based MP3 Jukebox (translated) which [Jose Daniel Herrera] put together.

He spent some time making sure that it looked great sitting on a shelf with his other audio equipment. This started with a wooden box which is some reused packaging. We’re not familiar with the ‘iNFUSiONES’ product; perhaps it’s tea or tobacco? At any rate, to this he added a custom face plate to host the character LCD, rotary encoder, two buttons, and to act as a grill for the two speakers.

The speakers and their accompanying amplifier circuitry were pulled from a portable speaker set. He combined them with a VS1002d MP3 decoder module, SD card breakout board, and the Arduino itself. In addition to the overview post linked above, there is also a collection of assembly photos, and a post discussing the way he arranged the code for the control systems (translated). See and hear the unit in action in the clip after the break.

Hackaday Links: April 29, 2012

More old computers on FPGAs!

[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.

If you’re going to build a jukebox, why not go all out? Here’s a touch screen jukeboxwith an LCARS skin. Yep, the same interface found on Star Trek: The Next Generation.

New desktop wallpaper for you

[McMonster] found a great pair of blog posts (1, 2) showing what ancient ICs look like without their casing. Since these were CERDIP packages (two ceramic plates glued together) they were exceptionally easy to take apart leaving the entire chip intact. Pages are in Polish, but there’s a Google Translate button on the sidebar

Cheap and easy Arduino wi-fi

Quick quiz: what’s the easiest way to get data onto an Arduino wirelessly? XBees? GSM modules? Nope, just get a wireless router and an Ethernet shield. The Ethernet module only cost [Doss] $20, and we’re sure Hackaday readers have a spare wireless router around somewhere.

Chiptunes! Chiptunes I say!

[mdmoose29] has been working on making a custom SNES cartridge for a dubstep artist (tell us more, [moose]…). In his search for programming tools, he found theSNES Game Maker. We tried it out for a bit and it’s still a very unrefined beta. Still, making SNES programming easier is awesome.

You people are awesome. Here’s six things for a links post.

[Valentin] made a night vision monocular from an old VHS camcorder, a small spy camera, and a handful of infrared LEDs. Here’s a video of [Valentin]‘s build in action.
