New Lunetta! AKA Mastodon!

I have returned from the other side of our solar system with many a tale to tell.  Let's get to the nitty gritty:  I am building another Lunetta (codename Mastodon) made from parts and ics that have been almost forgotten/disgarded from other builds.  The goal was to recycle and make the most of found objects to make something new.

I'll give greater detail over the cmos used but here is the general idea:  5 oscillators made with one 40106.  3 of them have cap switches (big and small).  2 different divider chips (4040 and 4020) which will give me many ways to clock other ic's or be used as octaves for the other important ic (the 4051).

There is also the pitch track 4046 which is as important to me as a mixer is to my lunettas.  I may tweak the 4046 to use some of the other outputs like pins 1 and 2, but that's dependent on time :).

There are a few logic gates as well as a 4031 and 4029 counter.  Lastly, the outputs get fed to a four input passive mixer.  This variety of chips should make for some glitchy, synthy fun! More soon!

I want to stress that using cmos to make music/beautiful or atonal, is not impossible.  Find your power pin and ground pin.  Put 50k-100k resistors on the inputs.  Add LEDS if you want.

Wire up the ins and outs to jacks, nuts and bolts and make a panel to hold them.  Power each panel to a central power hub and run off a battery or wall wart.  Don't just settle for an Atari Punk Console.  Make your own beast!

Communications with Curiosity Rover - Lunetta Track

Ahhh,  time alone to patch in peace.  After a busy day taking care of my boys, finishing my Honey -Do List, fixing dinner and tucking everyone in, nothing is more relaxing than this.

Well, ok, there's probably a few things more relaxing but you catch my drift.  For those into details:

I am using a few oscillators as clock sources for a 4040 (to provide octaves for the 4512 and 4051) as well as a 4094.  The 4094 is providing a few outs for the ABC controllers of the 4051 and 4512.  Each of the common outs of the 4051 and 4512 get mixed in my built in 4 input mixer.  The combined output then goes into a Rocktron VII Deadly Sins Auto Wah for filter control.  Then we hear this noise through my Vox Pathfinder guitar amp in rich, Monophonic Sound.

Latest Track:MasterControl


This track was done on my mini lunetta and features the 4052 ic set up to create the beat.  A 4040 provides the 4 octaves for its A and B controllers to choose from.

Nitetime Lunetta Lullabuy

  Lil' Adam turns 2 today!  That's about how long I've been on this Lunetta journey.  I kept him busy the night before patching the machines while momma decorated for the B-Day party.

Cd4006 shift register in action

  Time to score some more of these for backup...

I like this chip!  Being able to choose how many stages has huge benefits in lunetta patches.  Draal's usual approach,  wire everything to the panel.  Ins get 47k-100k drop down resistors.  The function diagram for this chip is essential for figuring out how to patch this sucker.

Lunetta #3 Test Run The 4029 is Fully Operational!

Here's a short clip of my current build.  It has a number of different logic chips and is powered by connecting to the other lunettas in my collection.  This clip shows the 4029 playing a little tune when I connect the Jam inputs with some of the 4017's outs.  It also has an oscillator going into its cock pin.

The name of this build is Pipboy and is the latest member of my luna-family.
The ics:
4029 up/down counter
4040 Divider
4020 Divider
4006 18 stage shift register
4070 gate
4078 8 Input NOR gate
4072 Quad OR gate
4031 shift register

All these ics are simply brought out to jacks (in this instance, nuts and bolts);  nothing fancy or complicated.  Just bring anything remotely an IN or OUT out to the panel :).

Dead bug module soldered

All done with the wiring.  Just need to connect nuts and bolts and find best way to attach it to mini lunetta.  Leds?  We don't need no stinkin' leds.

Spontaneous module#1: LogicGate

Add on module for mini lunetta: 4001 4070 & a 4006 18 stage shift register. Dead Bug style.The original plan was to simply bolt this sucker on to my Mini Lunetta but that proved a little challenging.  I had a wooden box just screaming for electronics to be stuffed in it.

I added it to another panel of ics, posted in the future as the Pipboy Lunetta.  And yes, this in an updated post due to some techie difficulties. ;)

This lunetta was done with many a spare part so it's considered my junk drawer lunetta.  The nuts and bolts with alligator clip connectors work out fine and dandy and I endorse it fully.  It fits the overall look of the piece I believe.

There's a pitch tracker being used in this clip and I find it an essential part of my sound lately.  If Jimi Hendrix had his trusty fuzz, then I can have my trusty pitch tracker ;).

4046 Pitch Tracker in its Simplicity

Here's another clip demonstrating how the 4046 pitch tracker adds tonal variety to the simplest of patches. You do not have to build a ton of intricate modules to ROCK.  Multiply this concept with more oscillators going into more gates or data selectors like the 4512, 4051, 4052, etc., and make some music.

I have made plenty of complicated patches no doubt; but I like to get the most bang for my buck in a more stripped down way as well.   Must be my "guitarist thinking":  it's not how many or how fast you play the notes.  It how you get the most tone dripping from each note.

Tiny Build

I am super slowly building a mini lunetta.  I am going to use an old sega genesis cart box for the enclosure.  The perf holds 6 chips so far.

Julu 2012 update:  Turned out to be to darn small!  See following posts to check out the final build!

Using the 4094 as controller for the 4512

Here's a lil' video of my lunetta playing a tune with the following ics: 1. 3 oscillators built from the 40106 2. A 4040 divider to provide octaves of the clock source 3. A 4094 to provide the ABC pins of the 4512 ic One clock connects to the 4040. I take 8 outs from that chip and connect them to the 4512. Think of these as the notes to be sequenced. The 4094 has Data and Clock pins that are connected to the remaining two oscillators. Pick any of the outs of the 4094 to influence the ABC pins of the 4512. The 4512 has one output pin so all your bits of sound simply need to go to your mixer/speaker. Get more complicated as you like ;).

Not So Daily Twiddles

Nothing beats getting through a cold on a hot, humid day than heading to the basement for some lunetta action. Ic's used are: 4051, 4094, 4018, probably 2 different gating ic's like the 4070 and 4011, and partway through the clip I send the output to the 4046 pitch tracker module to give some change in freQ.

A quick albeit dark, video LOL

I've been stuck in a black hole of sorts but did manage to sneak in some lunetta time. The ics I used: One oscillator as clock source for the 4040, 2 more for the 4094 shift register. These will be the data sources that I connect to the data inputs of the 4512. The ABC controllers of the 4512 are of cource three oscillators but you could mix that up with the outs of the 4094 or other logic. A B and C will dictate which "channel" shows its stuff to the common out pin of the 4512. This output goes to my 4046 pitch tracker to create some of the sweeps you hear. Hope to post more vids soon :)

New Sounds!

Sorry for the delay; life gets in the way of art sometimes :).  I am spending more time recording and experimenting than just build, build, build.  Playing our "instruments" should be at least a tad more important than soldering and stripping wires.

That is, until I come across a chip to die for ;)!

Keep making noise.....end transmission.

Back from the Abyss

Sorry for the looong holiday break ;).  I'm in the last stages of rehousing my lunetta to make room for a few modules I've been experimenting with.  Here's a quick look.

I'm recycling one of my many paintings here at Castle Draal to hold many of the modules.  The upper board will also have a few modules.

The blank wood panel will house the leds in a nod to sci fi  movies, which I'm a huge fan of.  More soon!
