This LP player is made entirely out of LEGO parts. It plays the songs encoded on each record, but not by using a stylus in a groove. Instead, each LP has a color code on the bottom of it which is interpreted by the optical sensors underneath.
In addition to its functionality [Anika Vuurzoon] made sure that the build looked the part. The horn is a nice touch, but you’ll also appreciate the rotating mini-figures on the front side of the base. To the right there is a hidden door that provides access to the NXT brick which drives the system. New records are produced using a couple of different tools. First off, the song is written using Finale, a mature musical notation program. That is exported and run through a second program which produces the colored disc design which is applied to the records. You can hear the songs for yourself in the clip after the break.

[Benjamin] built a sequencer that uses a turntable and light sensors to lay down a funky beat. If you like creepy videos with repeated gratuitous corderoy-clad rear-ends we’ve got you covered after the break. Art film aside, he’s got an interesting project. Four light sensors are mounted below the turning record with LEDs hovering above. His hatred for old LP records is apparent because holes must be drilled in a disc for the light to shine through. The four notes in the sequence can be altered in voice and color, along with controls for motor speed and direction. The project also has four manual inputs to add some variety to the repetitive beat sequence. It’s a bit less practical than the penny sequencer but fun none-the-less.

One of the most-hyped features of iTunes version 9 is the addition of “iTunes LP,” which aims to recreate the classic record album experience with artwork and photos, lyrics, and liner notes — provided, of course, that you can pony up the purported $10,000 for production and you’re not one of those filthy indie labels.
