Resurrecting a Hi-Fi cabinet

[VintagePC] pulled this old stereo out of a barn. It was in pretty shabby shape, but he managed get it running again and make it look great as well.

While it had been protected from the elements, it had not been protected from the rodents. Mice had chewed their way through the fiberboard backing and made a nice home inside. He mentions that they chewed the string which operates the tuning dial, and we’re sure they were the cause of other problems as well. He gives the wise advice of not powering on an old set like this until you have a chance to assess the situation.

The insides of the amplifier were about as disorderly as the last radio repair we looked at. But after carefully working his way through the circuits, replacing capacitors and resistors as needed, he started to make some progress. The receiver coil needed to be rewound and he used wire from an old CRT monitor for this purpose. The loop antenna was remounted and the record player arm was given a new cartridge and balanced using a clever LEGO apparatus. Some veneer work and wood finishing brought the case itself back to its original beauty. We’d say the hard work was well worth it. He’s got a big piece of furniture he can always be proud of!

Playing with routers, vinyl and music concrete

When Danish musicians Vinyl Terror and Horror visited [Daniel] and his CNC router at EMS in Sweden, things were sure to get interesting. The band uses heavily modified record players and modified vinyl records to produce strange soundscapes. During their time at EMS, Vinyl Terror and Horror were able to produce some strange vinyl that shouldn’t play on a record, but do.

Most of VTaH and [Daniel]’s work is centered on a CNC router. This soundscape took two records to produce. The spare rectangles were cut from a second record and designed to be press-fit into the host. When the newly assembled record is played, truly bizarre ‘skipping-but-still-playing’ sounds are made. The same process was used on the puzzle piece record the guys made.

The experiments continued by cutting a circle out of a record and gluing it back into place with a different orientation. This idea was taken to its logical conclusion that serves as the exemplar of music concrete.

[Daniel] and Vinyl Terror and Horror came up with a pretty neat spin (HA!) on century-old way of making electronic music, so we’ll give all of them some props. Check out all the videos from VTaH’s time at EMS after the break.

Broken vintage record player reborn as a portable MP3 cabinet

old_record_player_pc_jukebox

[Julian] picked up an old record player that was sitting in somebody’s trash pile, and brought it home to see if it could be restored to working order. When he got it home he discovered that it didn’t work at all, so he and his wife decided to modernize it a bit.

In an effort to simultaneously reunite himself with his music collection and piss off audiophiles/antique collectors in the process, he gutted the radio and began rebuilding it to serve as an MP3 jukebox. Once the innards were removed, his wife refinished the cabinet and gave the front grill a new cloth cover.

An old PC was installed inside the cabinet, along with a set of relatively cheap (but better than paper cone) speakers. A pair of custom cut plexi panels were used to cover the computer, while providing space for the monitor and Apple wireless keyboard + trackpad [Julian] uses to manage the jukebox.

The refurbed record player came out looking quite nice, and although it likely raises the ire of several different groups of purists, we think it’s pretty cool.

Light painting – still shots and animations

[Kim Pimmel’s] been doing some really interesting light painting with an Arduino. In the past we’ve seen several light painting projects which use long exposures to capture moving LEDs, or moving LCD displays. But [Kim’s] stepping it up a notch, using cold cathode flourescent lamps, electroluminescent (EL) wire, and lasers. The vibrant colors put out by these sources make for some great photos, but that’s not all she’s got up her sleeve. After accumulating a ton of still photographs from various shoots she decided to edit them together into stopped motion videos.

After the break you can see that one method she used to make these images was to spin the light sources on a standard audio turntable. An Arduino is controlled through processing via Bluetooth in order to move the stepper motor-mounted lights while the record player spins. Add some futuristic music thanks to Daft Punk (which is exactly what she did) and you’re in business.

Steam-powered Rickrolling

This is a steam-powered record player; awesome. But wait, that’s not all. Watch the video after the break for about two and a half minutes and you’ll realize that it’s also a Rickroll. No, you’re not getting baited into clicking through to Rick Astley’s music video, the LP that’s playing on the turntable is a copy of “Never Gonna Give You Up”; all kinds of awesome.

This all started with a steam engine machined from a stainless steel bolt and a brass cylinder. It was tested using compressed air before building the boiler. But what’s a steam engine without a purpose? The problem with using a steam engine as a turntable motor is speed control. This is where we move to modern technology, using an Arduino to measure the RPM and adjust the steam engine using a servo motor.

The builder makes a comment that this sounds terrible, but considering it’s steam-powered we think it sounds just fine.

Cybraphon, rocks hard to the mood of the internet

Start off with a beat, wood sticks on cigar boxes will do. Add some chimes as accent, a Farfisa organ or record player for a voice, several other instruments for harmony and dissonance, and you’re still just on the tip of the iceberg for understanding Cybraphon.

Not only is this antique wardrobe completely autonomous, playing music with over 60 robotic instruments, its song are based on the current mood of the internet. You definitely don’t want to miss the video (or pictures) on this one, catch it after the rift.

Cardboard record player

[Yen] tipped us off about this cardboard record player. It’s a marketing tool that you receive in the mail. Inside the cardboard packaging is a record and the packaging itself can be folded into a player.

Hackable handheld

The NanoNote is a tiny handheld housing a lot of power for a small price. It ships running openWRT and sports a full keyboard, 336MHz processor, 32 MB ram, and 2 GB of flash memory. Not bad for $99. [Thanks Drone via Linux Devices]

Virtual page flipping physical interface

Love reading ebooks but miss flipping through the pages? [Marcin Szewczyk] developed this interface that lets you flip a couple of sheets of plastic to turn and fan through pages on the screen.

Augmented reality tat

Not interested in supporting an ink artist or just can’t decide on the design? Perhaps you should get an augmented reality marker tattooed on your arm and have the art digitally added for those who have already made the switch away from using their analog-only eyes. [Thanks DETN8R via Asylum]

Cooking with a CPU

[Bo3bo3] is practicing the art of cooking with processors but he’s bumped things up a notch. Instead of cooking inside a computer case, he removed the processor from the board and made it USB powered. [Thanks Waseem]
