This latest addition to my growing collection of Project Diva: Future Tone controllers is a 1:4 scale version of the full arcade layout. At its heart is a Brook PS3/PS4 fighting board and four Seimitsu PS-14-DN 24mm buttons. Housed inside of a laser cut ABS case provides durability and style. In addition, this iteration features a brand new input method by means a capacitive touch sensor.

The touch pad is manufactured by Brook and has approximately the same dimensions as the Dual Shock 4 touch pad. The USB cable is detachable with a micro-XLR 4 pin connector and tech-flex covering for protection. While this is a finished prototype, the rough ABS edges are still far from perfect and will likely use white acrylic in the final version.

As for now, the controller is not for sale and the design will receive a few more iterations to increase internal space, strength, and ease of assembly. After these updates, the files will likely be uploaded to Instructables along with full assembly instructions. If I do manufacture finished controllers if anyone actually wants one of these tiny (but still fully usable) controllers, estimated price will be around $199 USD.
