A dummy question. Is it possible to transport a patch pd on a light electronic system, which is powered by a simple batterie?
I run PD on a mini-itx EPIA-5000 motherboard (www.mini-itx.com/store/default.asp?c=2#p1601) with just a laptop hard drive and this very light power suply (www.mini-itx.com/store/default.asp?c=10#p1804). The motherboard is only 17x17cm and by using Linux, you could easaly have your patch launched automaticaIy at startup. I use it this way for a piece I did (a PD controlled pinball machine) and have found it very reliable.
I guess you could replace the 220V to 12V converter by a battery.
Hope this helps, Julien
