Here is a video of my latest project the Hexome.
This is a hexagonal based monome.
Hexagons are cool but a bit of a pain because their spacing involves a root 3, a non rational number. This means you can't lay it out on strip board, it needs a special PCB. That's why I built my CNC project mainly to do this project.
The hexagonal spacing allows different sorts of sequencers to be built with sequencing tracks going off at different repeating rates. I have only just begun to explore the possibilities that this opens up. It also allows a more comprehensive way of generating a keyboard for music.
Full construction page to follow in a few weeks, after I show it at the UK Maker Faire in Newcastle 12 / 13th March.
