Laser Harp Mk III (with added WiiMote)

by Stephen Hobley on March 23, 2008

It looks like I’ll be doing an interview with WFYI on Monday about the Laser Harp and the sudden popularity of the video on YouTube.

I thought I’d better get version III going – using the PixArt sensor on the front of a WiiMote to control expression.

Basically sliding your hand along the beam can now be programmed to control any of the standard MIDI continous controller parameters.

Pitch bending is treated a little differently in MIDI, and I’m having a few extra issues in scaling the output of the WiiMote to the 14 bit integer values required. All standard 7 bit controllers work fine.
