Have you got a thread about the details of your lunettas, Draal? Seems like you should make a nice little compendium now "Ye Threade of Ye Olde Draal's Big fuggin' Lunetta" _________________ As a mad scientist I am ruled by the dictum of science: "I could be wrong about this but lets find out"

Thanks for the comments guys! I have a pretty amateur blog mentioning some of the things I've built, tested. I do need to make it a bit more polished with more pics and descriptions of my machines though. Time is my enemy !

You need to make a thread for that and fill it with demos! _________________ As a mad scientist I am ruled by the dictum of science: "I could be wrong about this but lets find out"

Hello everybody,
to introduce myself, here is something that qualifies as a Lunetta, a 4093 NAND (left, wooden box) patched into an APC (green box). It has almost every mod I found on the web, 3 modulation inputs and a 555 LFO. What I like best is the starve pot, which makes it very noisy together with the additional pots and switches. I am not really able to play it the way I see it on all the YouTube videos (a quality I like).
Note the cases: The green one is from the Swedish furniture outlet, the plastic is nice to work with and you can take off the lid, which is great for drilling and soldering.
The left one (wood) is a cutlery box from the same furniture outlet. I bought several of them because they were dirt cheap, look nice and I bought some birch plywood to make faceplates for them. Someday I hope they will end up as standalone with proper plexi or metal covers.
Above, you can see what I am working on: an old violin case that will be the home of my Lunetta (the 4093 will be the first module). I want it to be a self-contained machine which I can play on my lap, that's why I put a speaker in it (silver, left side). The woodwork is almost done (glueing cracks, inserting the plywood for the faceplates/controls), next is soldering and drilling.
Let me end saying that I have been lurking here for quite a while, and want to say a big Thank You to all you people sharing their knowledge here and elsewhere. I have learned a lot from you, Kudos.

wow, that was beautifull! thanks for sharing textual _________________ There he goes. One of God's own prototypes. A high-powered mutant of some kind never even considered for mass production. Too weird to live, and too rare to die.

A little jam with my thing, which is STILL on the breadboards. It's getting close to critical mass, but there are still details I have to work out before building a more permanent home for it. And a good name to find for it!
In the meantime, some fun. In this video: a pseudo-random 4-bit generator (40174+4070) feeds an R/2R DAC. The resulting voltage is split and sent to two things:
1. a 4046 VCO with a glide control
2. the CV-in of a 4023 pulse-width-modulation oscillator, which then goes through a triangle waveshaper (4011+4015).

Really nice Ringmad.
What did you endup doing to get glide/slew control?
If it was my suggestion: Pre-emptive you're welcome.
If it wasn't: pre-emptive, thanks for the tip _________________ As a mad scientist I am ruled by the dictum of science: "I could be wrong about this but lets find out"
Except I used a 15nF cap and half an LM324 (in unipolar)... which isn't a JFET opamp AFAIK, but it's what I had to hand and it sounded good to me, so didn't bother digging out a TL072 or something. Using a cap larger than 22nF seemed to mangle the sound too much for my taste... the way I have it now gives a nice triangular sortof sound I like.
I hadnt seen this thread but Its very similar to the slew I used on my R2R DAC module.
Reading through it gave me the tip on how to fix the pitch drift when turning the pot.
Thanks and great sounds.

Modular Lunetta
Last week I finally started on a modular lunetta system. I really like banana's (jacks and fruit )
but they are a bit too pricey and you need a lot! And the PCB connectors are a bit to flimsy for my liking.
So I decided to use the bolts and crocks method after having some experience with this (and being
quite pleased with it), when I was working on some synth stuff.
but what really got me started is when I realised that I could use perfboard to make the front panels.
It's very easy to cut to the right size, you can solder components on it directly (great for mounting LED's)
and you don't need to measure anything when drilling holes for bolts/switches/jacks and whatnuts.
just count the holes for the right spacing.
I used PCB connectors to mount the boards that hold the chips and other components. and on some modules
I also used them as an actual connector at the same time. I'm not completely sure yet about what I'm
gonna use for the power distribution, but I think I'll use cinch connectors like attdestroyers (but with + & - combined)
And I just found out that the space between the mounting holes and the edges of the fronts is just
right to mount them on a rail spacing between top and bottom isn't a standard rack size so I have to
make something custom, but this will make mounting the modules very easy.
so here are some photo's I'll post more info about them at some later time, but feel free to ask,..
