It's good stuff, it just hasn't made it to the top of my list yet (and we hit the wall in arduino).
I think you would do well to just make a "Skellys arduino based mpguino mods" wiki page with the code embedded in it to cut and paste into arduino. I can add a pointer to it from the top of the pde file in googlecode for the adventurous sorts. And of course a pointer from the code hacks page.
Also, you might want to incorporate the changes for .75, some fundamental accuracy fixes in there, and of course keep an eye on the mpguino update thread if you are going to try to keep it current. This way I know there is a well tested version published on the main site, but there is a path forward the adventurers. I just can't personally help them much these days, and they are good at getting into trouble
Thanks,
Dave.
P.S.: the prebuilt does not come with any guarantees either, but I do try extra hard to make sure it works
My reputation is worth something to me.
