What is Project Kajitsu? Project Kajitsu (Kajitsu is Japanese for Berry) is the brain child of Mike Wolak and Jasen Hicks based on the $35 Raspberry Pi B+ Model. The goal was to use the Raspberry Pi with a custom Pi Hat / Linux kernel and turn 2 ordinary PS3Read More…

Project Kajitsu Update: DB15 USB-Discrete Board

Mike and I wanted a simple solution that didn’t require some fancy cable or hack job to connect to the screw terminals so we came up with the Kajitsu USB-Discrete only version. This only converts USB (PS3 and XBOX 360) to Discrete Output using 5V logic. Its slimmed down onRead More…

Project Kajitsu Wiimote Support

Nintendo Wiimote

Wiimote Bluetooth support is now being tested. This demo shows the Pi booting and pairing to a Wiimote.

Noritake VFD

This video illustrates the Kajitsu Pi Hat being used as an interface between a Noritake VFD Display and the Pi B+’s GPIO pins. The octal buffers provide line driving capabilities and also protect the PI’s 3.3v I/O pins fron the display’s 5.0v RDY line. This demo uses the same I/ORead More…

Project Kajitsu Bluetooth Proof of Concept

Although it’s not active in the initial release, Bluetooth testing with PS3 Sixaxis pads works well. We need to figure out the best way to simplify the pairing process but functional tests were 100% successful.
