Thanks mosc! as we all know a picture speaks a thousand words, and a video is made of thousands of pictures! meant to say there's a few video's on you tube, here's my favorite
i love this thing. thinking about how to make it slightly more rugged.
sndbyte - your aesthetic is beautiful, the sounds are nice and crunchy too. does it also have an output jack?
Thanks for the comment. 2 of the 3 digital logic noise things I made do have output jacks (the one in the gray box, and the larger wall mounted one). The small natural colored box does not have an output jack, but instead has 4 piezo discs mounted under the pcb. It is a really quiet instrument, but I really like the sound of clicking piezo discs. Of the 4 short videos I posted on Youtube only 1 uses an output jack hooked up to an amp. The remaining 4 are just the piezo discs clicking away which is why they are so quiet.

My Lunetta Rehouse Project BlobLore2.0
Here's a little clip showing the status of my rehouseed lunetta. My old one was smaller and used nuts,bolts and alligator clips. The new machine has nanners now and I'm pleased as hell.
I added leds this time too, but I'm using them in a more 'sci fi control panel' way. Going for atmosphere as opposed to doing what's expected. The featured chip: the 4018, 2 of em, playing a little ditty.
Almost done with her; still need to add guitar/mic input....
2 gated oscillator channels (osc/osc and osc/audio input) + a stereo vactrol auto-pan/gate circuit + voltage starving + jacks for the inputs and outputs of the oscillators, audio input and pan/gate.
my lovely little PLL Pitch-tracking Oscillator. lots of weird options on this. basically an elaborated version of the design in the Nic Collins book. a 4040 is used to transpose notes up an octave.
here's a clip of these two boxes interacting. plus a delay.

Early days!
Well, this is a long long way from some of the gorgeous and fantastic things posted on here recently but it's a start
So far it's just a stripboard 40106 with 4 nice slow adjustable outputs and a breadboarded 4094.
It doesn't make sound because I intend to use it to produce interesting trigger patterns for the Thomas Henry Quad Bass ++ that I'm building.
Just need to spend some time now working out how the strobe, data and clock interact on the 4094 by watching the blinky lights until my head spins!
Many thanks to all of you for inspiration and to Rykhaard in particular for banging on about buffering caps often enough that I got the message. They solved all the problems I had whilst building this (apart from the ones which were just down to my own stupidity which I could fix after staring at the tangle of wires for long enough!)
Hopefully there will be more to see soon.
Cheers
Ian

Ian, that's the way to do it. Once you figure it out then worry about a package.
Kaput, great looking apparatus. Using clip leads and screws is a great methodology. Effective and inexpensive. _________________ --Howard

Thanks Mosc
Against all expectations it is beginning to make sense.
I'm quite chuffed here and ready to start soldering more sockets onto stripboard for the stripped down Pulse Divider that Bruce suggested. I'm quite excited to be able to look at Ken's schematic and have a pretty good idea what's going on. For an electronic illiterate like me that really is progress
As for Kaput - that looks lovely - another set of good ideas to pilfer and adapt!
that is one hell of a nice machine you have there. Really like the small size, what cmos ic's did you use? _________________ 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.

machines used for moOndIscOo
The bigger mothership box:
top left to bottom left (blue, red, green orange) are oscillators done with a 40106. they all have cv in (done with 3904, mosfet, or vactrol-> the one used for the beat), pulse/square out and also a more filtered spike/triangle out. they all have a capacitor switch.
pink is a 4024 and purple a 4040 (with a rotary switch to select the two outputs right to it 5,6 - 7,8 - 9,10 - 11,12)
turquoise is a multiple
yellow is a 4051 with many small pots so it can be used as a sequencer
the small dark blue is just an inverter
the red down left is a 555 used for pwm with 40106 buffers and also a cv in (vactrol) and a capacitor switch
the green and dark red is a 4015 shift register
the orange one down right is a r2r ladder
there are many connections done by default, so that it already starts blinking when no patching cables are connected and also cables can be saved.
the smaller firecolored box:
4051 but this time not used as a sequencer, but can be used as signal switcher
4017 connected to the 4051 (melody generator)
a 40175 with clock input can be switched on, so that the melody generator fits better to a beat

Johannessy, I really enjoyed your Lunetta video - the tremendous variety of the sounds is impressive! At first I liked the "normalness" of the early sounds , then before I got bored with that you switched to wilder stuff and later woke me up with t truck horn, wow! Then at the end you wind things down by unplugging the machine - a nice touch. Well done.

This circuit is the subject of this week's The Les Hall Show, friday at 5pm EST on electro-music radio. It's got a microphone circuit, a modulated 40106 oscillator, and a boolean sequencer with state memory and linear CMOS output stage. It's really quite a contraption and I'll post an audio file of it in an hour or two once I get it recorded.

I must repost this to the correct thread. It is my first enclosed music circuit. I scrounged for all I had to make it. The industrial looking guard rail protects the jack, cable, and switch and give it a sort of a steampunk look. All aluminum parts were slowly brushed with a Dremel sanding drum. It turned out nice. How does it sound? eh, just OK. Vaguely percussive - actually it makes an "angry chipmunk" sound best of all.

Here is the recording of the above photographed breadboard. Listen at 3 minute mark for the best part, but all of it is good in the sense that it illustrates the circuit resonating in response to my voice.
I've started working on my expansion board. I filled in 6 of the 9 spaces on the board. Now I just need to figure out the final 3 and then mount it.
They are:
CD4024: 7 stage divider
CD4060 14 stage divider
CD4017 sequencer (with a fancy bar graph for lights!)
6 patching strips with LED
CD4046 VCO
and finally at the bottom a de-bounced toggle flip flop swtich using a CD4001 and CD4013. The CD4001 is used to debounce the CD4013 flip flop.
I checked, I'm trying to message you.
I hope you'll see my message here
I just finished a small portable lunetta. It is 6 chips on a small PC Board in a wooden box I found at a craft store.
Here is a breakdown of what you see on the board (starting from the top left hand corner):
3 patching strips with LEDs
CD40106 with 3 oscillators (1 low, 1 mid, 1 high)
CD4040 divider
CD4051 binary switch
7805 voltage regulator
small piezo buzzer
a on/off switch
CD4011 NAND gate
CD4070 XOR gate
CD4051 shift register
another small peizo buzzer
2 4-hole headers that connect to the 2 piezo buzzers you can see and the 4 piezo discs mounted below the PCB.
The 9 volt battery is below the control panel.
I'm looking for a box like that but aluminium. any address/url in europe?
