Syst3mX posted instructions for building an affordable 8×10 matrix display for use with Arduino -
In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex.
4017 chips can be had for a quarter or so – alternatively, the popular MAX7219 display driver goes for about 10 bucks! Of course each approach has its merits. Project steps plus excel layout sheet over @ Instructables.

Holy Wow – Marcus’ love for digital organ emulation inspired him to emulate the instrument’s physicality as well. Modeled closely after the Hammond B3 organ, the B4 Controller is designed specifically for use with Native Instruments B4 (II) virtual organ software. On top of a hefty amount of good ol’ woodworking, funcionality was developed with Arduino/etc -
Most of the electronics had to be custom developed as there was nothing available to cover all the functionality of a classic Hammond B3 with the full drawbars set, preset keys and all switches. The Arduino platform was of great help for doing all the prototyping.

The electronics for the white keys section of the two manuals as well as the actual manuals where bought from Doepfer. The manuals are the same as used in the Nord C1 and Nord C2 combo organs and are manufactured by Fatar.
Much more info a photos from the build right over here.
