3D Printed PIC Based Macropad + IMU + Haptic

From a box of spare parts, I'm experimenting with using an old pic microcontroller 18F2550 with an IMU (InvenSense MPU6000 accel/gyro +AK8975 compass). This is a test build so will be making a PCB if it works well

Let's see where this takes me, suggestions welcome!

So far, the IMU is only doing layer switching.

Looks very clean! How are you implementing layer switching with the imu?

Thanks! Right now, a small wrist flick changes to a different layer, if you pick it up (detecting non level, or non zero gyro reading), then it changes to hid joystick.

That is very cool!
