What kind of DIY projects are you currently working on?

I'm scheming out a homebrew computer based on a couple TMS-9900 CPUs salvaged from broken TI-99/4As...not that I'm likely to ever get anywhere with the projct, but you know, fun to plan at any rate

I remember I drew up a plan to make a portable SID player in 1994. It would consist of a cpu, sid and the corresponding electronics + memory to hold sids.

Reminds me of my other "eventually, someday" project to create a Minimoog-style monophonic synthesizer using a SID chip...

Plenty of nice C64 mods around, but here's a quick and easy option I turned into a keytar: http://www.qotile.net/cynthcart.html

There is that, yeah, but I'd like to do one layering the voices similar to the Moog's three-oscillator monophonic synth. I believe the MSSIAH cart includes a module for this, but then I'd have to buy a MSSIAH cart, and anyway it'd be fun to do my own

ExpressPCB, too.
