The Dyskograf lets you make music with a magic marker. The musical installation looks much like a turntable for playing vinyl records. But instead of a spiraling groove containing the sounds, this uses marks on a paper disk to play sound samples.
You can see the light outline of several tracks on the paper disc shown above. By adding black marks the optical input of the Dyskograf knows when to start and end each sound. This is best illustrated in the video demonstration after the break.
The marker-based setup makes a lot of sense, and we think it would be perfect if the disc was a dry-erase board. It certainly makes it a lot easier to lay down new beats than this other optical turntable which required holes to be drilled in a vinyl record to play the sounds. While we’re on the topic you may also find this coin-based turntable sequencer of interest.

From the look of it his is just another Word Clock, right? From the outside maybe. But if you take a look at the build photos this a good example of extreme fabrication.The design uses a five-layer lamination of glass bezel, vinyl lettering, diffuser, mounting plate, and back panel. The mounting and lettering layers were labor intensive, but are also the reason for the gorgeous finished look.
The bezel consists of black adhesive foil applied to the back of the glass faceplate. The letters were cut out using a vinyl cutter, and the lamination process happened in a pool of water. This technique helps to ensure that no fine particles end up between the glass and the foil.
The wooden mounting bracket was ordered from a local kitchen cabinet fabricator. It’s MDF that is 17.7″ and has been edge wrapped in glossy white PVC. Once it arrived, [Muris] started drilling the 248 holes and their counter sinks. This is on the front side of the layer and when sprayed with silver paint the countsinks act as reflectors. On the back side he milled groves to accept PCB strips to host the LEDs as well as the breakout boards that hold the MAX7219 drivers.

Vinyl records are an amazingly simple technology, but surprisingly we haven’t seen many builds to capitalize on the ease of recording music onto a vinyl disk. [Seringson] made his own
vinyl polycarbonate cutter to record his own records at home. The impressive thing is he did this with parts just lying around.
Just like the professional and obsolete record cutters of yore, [Seringson]’s build uses two speaker drivers mounted at a 45° angle to reproduce a stereo audio track. Each of these drivers reproduce the left and right audio track by carving them into the polycarbonate of a CD with an extremely sharp needle. From the video, the audio quality of [Seringson]’s record cutter is pretty good – more than enough to recreate the sound of a 1940’s 78 RPM record, but not quite up to the task of reproducing something produced and mastered recently.
We’re extremely impressed that [Seringson] was able to a record cutter out of scraps he had lying around. Now we’ll wait patiently until a combination record/CD is released.
Tip ‘o the billycock to [Gervais] for sending this one in.

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.

The Royal College of Art in London recently hosted its annual graduate summer show, where postgrad students exhibit some of their artistic and musical projects. Among those featured this year were several vinyl record and turntable mods by [Yuri Suzuki].
