Vinyl remains a popular format, despite taking a huge hit in popularity for a couple decades while CDs ruled the roost. It has a charm that keeps it relevant, and likely will continue to do so until everyone who grew up with a record player dies out. In the meantime, [sp_cecamp] has come up with a great way to experience your collection, with the magic of modern technology. It goes by the name of Plynth.
Fundamentally, it’s a small record stand with an excellent party trick. The prototype consists of a 3D-printed body, which holds a record sleeve at an attractive angle for display. A camera built into the base then images the artwork. The first image taken is run through the Google Vision API, and further images are then run through OpenCV to identify the record. This data is then passed to the Spotify API to play the track. The whole process takes a couple of seconds, and the music is then pumped out of whatever streaming device is connected to the rig.
It’s a fun way to play your old records, and would be a welcome change to those tired of screaming at Siri to play Weezer (Blue Album), not Weezer (Green Album). For those interested, [sp_cecamp] has thrown up a site to gauge interest in the project, and may make a limited production run in future.
Of course, you could instead just go about building your own turntable. To each their own!
It’s often said that the music etched into a vinyl record takes on a transcendent quality that you simply can’t find in a digital recording, but does that still apply when you add motion picture? The collaboration of [Sengmüller and Diamant] sure think so, because they are offering a new experience for the turntable with the introduction of their VinylVideo pre-amplifier. No tape reels here, this project shows the extend of what is possible through analog video.
While all record players capable of playing back 7 in. 45 RPM are compatible with the system, the VinylVideo records themselves specially cut in order to generate the video signal. Each of the custom records has room for a 4-minute music video on the A-side, and the single on the B-side. Videos play back in black & white, sub-standard definition with mono audio, and run around 12 frames per second. The pre-amp takes in the analog signal from regular audio cables via RCA jacks or 3.5mm headphone jack, and then a Raspberry Pi model A+ handles the analog-to-digital conversion. Video out options include HDMI and composite video via a 3.5mm TRSS jack.
The current VinylVideo pre-amp is actually a refinement of the original project from the mid ’90s where it was a part of folk art exhibits. The legacy website (circa 1999) is still live, so you can give it a visit. However, for the most authentic experience you may want to fire-up a virtual machine with Netscape Navigator and Real Player installed.
For a more in-depth look at the VinylVideo in action there is a great video below from [Techmoan]:

Old timers who have been around for the last 40 years or so have been fortunate enough to have lived through several audio reproduction technologies – Vinyl Records, Cassette Tapes, Laser Disks and CD-ROM’s. Most will also swear that analog, especially vinyl records, sounded the best. And when it comes to amplifiers, nothing comes close to the richness of vacuum tubes.
[MCumic10] had a long time desire to build his own HiFi turntable encased in a nice wooden housing, with the electronics embedded inside. When he chanced upon an old and battered turntable whose mechanism barely worked, he decided to plunge right in to his pet project. The result, at the end of many long months of painstaking work, is a stunning, beautiful, wooden turntable. Especially since in his own words, “I didn’t have any experience in electronics or woodworking before I started this project so it took me many long months in learning analyzing and frustration. I burned some electronic parts few times and made them from the beginning.”
The build is a mix of some off the shelf modules that he bought off eBay and other sources, and some other modules that he built himself. He’s divided the build in to several bite sized chunks to make it easy to follow. The interesting parts are the 6N3 Valve Preamplifier (the main amplifier is solid-state), the motorized Remote Volume Control Input kit, and the Nixie tube channel indicator. And of course the layered, plywood casing. By his own reckoning, this was the toughest and longest part of his build, requiring a fairly large amount of elbow grease to get it finished. He hasn’t yet measured how much it tips the scales, but it sure looks very heavy. The end result is quite nice, especially for someone who didn’t have much experience building such stuff.
