More progress on my Lunetta CMOS Synth

Ok it has been to long....

Time for progress shots of my Lunetta CMOS Synth! As you know the concept of behind this machine is to use 4000 series logic chips wherever possible and to keep any invloved circuit as simple as possible in it's construction. Mine used to live in a cardboard box. That is slowly changing.

The panel work continues, and adding more modules as I go:
Top Row:
6x 40106 oscs
555 timer

Bottom Row:
Little Summers
3x R/2R DACs
1x Portamento
Space for the Simple Diode VCAs Richard64 linked to. (Will also do the other two he posted as panels.)
2x YAVCO (One so far)
2x NAND VCO (One so far)
2x 4051/4017 Melody Gens (One so far)
4 Channel Mixer with 1/4" out

And there's another shelf under this to fill.

Next up are some parts of my growing portable kit.

All the patching will be done with header leads and those cool breadboard connector leads that come in big bundles.

The Clockinator : 4 4093 PWM oscs hardwired to 4x 4040s
Shifty NAND Squid : Hardwired NAND > 4015s
NAND Photo Synth ! Just for fun. Output to guitar amp, finally a use for my phototransistors, plus these wierd momentary toggle switches i picked up along the way... More on that in another post.

Hope you like!

The wiring continues...
