Hi all!
I've been lurking here for a bit and finally have started building a lunetta of my own. This is a whole new world for me and is a lot of fun.
Anyway, here's what I've got going on right now:
A 40106 driving 6 oscillators. Three are completely hooked up and three still need to be wired up to the panel
A 4093 quad gated oscillator
A 4046 pitch tracker
A LM348 based tone generator kit that has been tweaked a bit to turn it into a VCO
The infamous Slacker Melody Generator
A 8 input passive mixer
And finally a WSG (my learn to solder kit )
Combining the melody generator with the pitch tracker is more fun than it should be.
Here's some videos:

Draal welcomes you, former lurker .
Really nice looking lunetta there; diggin' the knobs too. Very good set up of modules to play with. The pitch tracker to me is like what a fuzz pedal is to an electric guitarist; a simple but powerful sound enhancer. Even just running two separate oscillators into a gating ic like a 4070, 4011, 4001, can produce huge varieties to timbres with the 4046 pitchy.
Well done _________________ Zontar Prevails! |

Welcome to Lunettaland, autowitch. You are definitely off to a good start... nice machine you're building!
James. |

I have been having a lot of fun with it Learning a lot! I haven't decided if the building or playing is more fun.
I just added a 4040 divider last night - I think putting in more logic gates is next. That should lead to interesting things. |

Dividers like the 4040 come in real handy for me. They are the "notes" that get selected in patches when connected to the 4051, 4052 or 4512 data selectors. Easy way to get different pitches.
And yes indeed, a few logic chips help create interesting strings of beats to manipulate.
I have two lunettas currently and I treat em like old Chevy's. Love em and I'm always changing out a few parts; never really "done". _________________ Zontar Prevails! |

The problem I have with the 4040 is if you want to use the divisions to trigger drum voices, you will have to invert every output to bring it all into sync. It's a real pain as it increases the IC count or involves a lot of transistors.
If you just want to make beep noises then this probably wont concern you. I wish there was another IC which didn't have this issue. Perhaps there is and I haven't found it yet. |

I hear ya, minus. My machines are nothing close to a drum machine ! More like conversations between Galaga and Asteroids arcade machines.
There I go dating myself again . _________________ Zontar Prevails! |

ha! Well there was one thing you posted somewhere which I thought was interesting... although I'm not sure where. It was where you used maybe just 3 IC's in a patch. It was a video I think.
It's easy to get over ambitious with these things. You can do a lot with very little if you choose carefully. There seems to be a convex curve to this Lunetta thing. It gets to the point where adding more ICs does less to the noise than they once did when you had just a handful to play around with. There might be a point of critical mass .
In fact, I have made sounds with just ONE IC which give much more elaborate machines a run for their money in terms of random hands off blip bleep crackle click blooping. |

@minus: Probably something like the 4046 pitch tracker video where I ran 2 oscillators into a gate of some kind and the output was fed to the tracker. Tons of variety with just those chips made me rethink how big a lunetta has to be to be "worth it".
I remember many a night trying to come up with something really cool by plugging more stuff in and getting frustrated. In the end, I realized simpler IS better .
Grand statements right? Maybe, but after spending a few years on these like you and I have - affords us some... leeway .

I was going to try to use the 4040 to trigger drums. I hadn't thought about inverting the outputs. That would go against my plans on keeping modules as simple as possible. Plugging it into an R/2R ladder is fun. Provides plenty of beeping - and that makes me happy. |
