It’s been a while since we’ve seen one of these. [vscd] sent in the flikr stream showing off the gorgeous MB-6582, built by [wilba]. It’s a diy midi synth that’s based on the midibox platform. It uses … synth chips to do the dirty work, and some PICs, a little CMOS hardware and a C64 PSU. He even anticipated some future versions of the midibox project to complete the design. This is one of the nicest DIY builds I’ve seen in a while – just beautiful work. Check out the build notes on the wiki page.
