Probably the biggest Arduino based Monome
Oh yeah!
A 256 buttons Monome in action. I was the other night on Arduino’s IRC channel on Freenode (/join #arduino at irc.freenode.net/8001) when Bastian Chroos posted a video about a 256 buttons Monome. I couldn’t help it so I asked him for some pictures just to check the wiring of that board. Here you can see Bastian’s prototype in action and a picture of the back of his PCBs.

Bastian said that he used:
– 1x Arduino
– 2x 74hc595 (giving voltage to the rows)
– 3x 74hc165 (sampling the columns button states) 1x 8 extra input.. so I
totally get 256+128 buttons..(16 encoders extra and 4 menu buttons are part of the plan)
– 4x MAX7221I did all the code and boards by myself [using Sparkfun parts] but I haven’t implemented everything yet. I just took the basic commands to clearly use the applications.
If you want more information you should look for Chroos on the IRC channel or visit his myspace profile where his music can be found. I got promised some extra pictures soon … neat!
