I've been working on a Lunetta recently and finished up a full PC board full of modules. Below is a scan of my notes I used to keep track of what ICs I used as I built it. This is the actually layout on the small board. I'll take a photo tomorrow and post that.

Excellent work! I think that is the most logic(phun intended) layout Ive seen yet, very good choice of ic's. Is it just bare perfboard or mounted behind a front panel? Can't wait to see some pictures.
I would also suggest a 4052 and some sort of 4017 sequencer, they are great for making rhytms.

Thanks for the video! Really nice machine you have going there, when did you start working on it? I really like the portable suitcase design, looks like a really playable design.

thanks for the kind words!
i wish those mixers were more responsive... i guess i'll have to try lower the pot value to 50k. they mute the sound until about 50% turned up, then its a very sharp rise, could be a log/lin thing but i bought those pots from an overstock place so i dont know much about em. _________________ home made noise and electronic ill-logic
I just took some photos of my work in progress. This took me about 2 weeks to build (being unemployed, I had a lot of free time last month). I got a lot of inspiration from the Absolute Beginners thread and the Lunetta Doc posted on this site.
This is the first time I built something without an enclosure or traditional panel. I decided to go the perf board route but I wanted to mount it on a board so it could be easily moved around (and even mounted on my wall!). The perfboard is mounted on a piece of painted wood (hammered metal spray paint). I have 2 perfboards. One large and populated and one empty and ready for more modules.
There is a 1/8 output jack but I also have 2 piezo speakers mounted on the back. You'll see 2 wires, one green, one red that are hooked up to the piezo discs. This is an easy way to quickly listen to the output of any point on the board without using an amp.
Also I should point out that I used 2 different type of sockets on the board. The square sockets are inputs and the round metal sockets are the outputs on a given chip.
I think there are over 80 leds on this thing (blue, red, green, orange, yellow and white). The leds are all clear so I slipped a piece of black heat shrink tubing around each. Actually, there are 8 square red leds for the sequencer... I forgot about those.
It is all run off of 5 volts with the exception of the WSG filter which is 9 volts. I also have a starve pot and a 3 input mixer.
Now I just need to figure out what to add on the expansion board!
Thanks everyone for your help, ideas and inspiration.

I used 2 different type of sockets on the board. The square sockets are inputs and the round metal sockets are the outputs on a given chip.
My method to distinguish inputs from outputs thusfar has been to make multiple outputs and single inputs.
But I noticed you used another trick I've been thinking of but not done yet. You've grouped the outputs and the inputs together.
example: the 4015 dual 4-bit shift register (near topright of your board) has the outputs of section 1 at pins 5-4-3-10. Inputs for reset, data and clock are pin 6-7-9. Not very convenient indeed.
The back of your perfboard must look like a rat's nest of wires crossing to the proper in/ out assemblies on the component side, hehehhe... but I'd do it like that anyway on my next build.
Yes, the rear of my perf board is a rats nest of short wires. I really wish I had taken a photo of the backside before mounting it. Below is a shot of the backside after I had finished the first 3 modules (40106 osc, 4011 NAND gate and 4001 NOR gate). You can also see my notes that I used to determine the placement of components in the 10 x 12 area which each module is allocated. I tried to place the inputs and outputs on the perf board so that they were easy to use.

Where do I start? Ah yes, the looks . That is probably the best and cleanest lunetta I have seen so far. I really like the little sleeved leds, the ins/outs, black perf and you've really thought about the ergonomics of actually using it! I build mine in a quite similar way so I know how hard it is to do all the wiring underneath to keep it clean, it gets messy fast. You've done an amazing job, keep it up, and I would love to see a video of this pretty beast in action.

Yeah now you have all the basic modules in, you can try some other cool things. I would suggest a 4052, 4046 VCO and maybe a 4094? First thing that popped in my mind for that spot would be the trusty old breadboard, that combined with the basic modules would give you a very usable machine.

Thanks for the kind words. I don't have a video camera but I did attempt to make a video using a 6 year old Digital Camera. The sound quality is horrible as is the video quality itself. But if you like blinking lights you may enjoy it. There is no amplification, it's just 3 piezo disks connected to the CD4015 shift register. This will give you an idea of what kind of clicking patterns you can make with it. The only thing I'm doing in this video is slowly adjusting the 40106 osc that feeds into the cd4040 divider (which is the sample for the cd4015 shift register). The clock is not being adjusted at all (it is a mid range 40106 osc). The sound is really low and you may even need to wear headphones to hear it.

Thanks for shooting a vid! I actually really like the clicky sounds, I think the way the piezo turns on and off is very different from a normal speaker, this would be great for a percussion backing track. I would love to see a vid with some more light and good audio, try recording on the line in of your pc.

just recorded this wonky noise jam
Very wonky indeed! That howling sound wasn't from your lunetta right? Keep it up and try recording seperate audio next time, it really makes a difference.
Really liking the new progress here, this forum was a little quiet a few months ago but it has picked up fast! Good job guys. _________________ There he goes. One of God's own prototypes.

Read upside down, the 101010, comes out as Oi Oi Oi
And of course, the centred zero is the standard Anarchy symbol.
Also, 101010 is 42 in decimal, which is as we all know the answer to life the universe, and everything.

That was, I believe, the realization that cinched it

Looks like the Monolith from 2001. Makes mine look like a Happy Meal
