2012 Build Pictures

#1 in a series of noisemakers i plan on producing, the idea is to sell them, they will be made on breadboard, transferred to perfboard and the original then disassembled, making each unit unique, i keep no schematics of these designs.

I finally got around to finishing my row of Frac modules, the modules are all of my own design, panels are from FPE.

1x Tuneable Noise, base on my pcb layout for the Liquid Hi Hat
1x Gate Delay (New version)
1x LPG, my own layout
3x Gate Delay (old version)
3x Voltage Controlled Clock, based on the Aries clock module
3x XR LFO, LFO based on the XR2206
2x 8 Channel Sequencers

The old version of the Gate Delay just delayed the start of the gate, it still ended when you released the key, I wasn't happy with that,
so I redesigned it, the new version has 4 modes,
Normal - works the same as the old version
Extended - Delays the start of the gate, and lets you extend the gate past the point where you release the key
Manual - delays the start of the gate, and lets you set a specific length, regardless of whether the key has been released
Timed - delays the start of the gate and keeps it on for the same length of time as the key was held down.

The sequencers can run of an internal clock, or the length can be set individually for each step, they also have a Cascade output so you can chain them together,
the time between triggering the next sequencer in the chain is adjustable.

I am currently working on a couple Midi projects (I'm using blue panels on them), and a cv keyboard retrofit for the cheap (M-Audio) Fatar keyboards
I am also in the process of building a CNC engraving machine, so I can start doing the panels myself.

This is a silly and simple little build for a laugh. After the disastrous Sweet32 Speaker Interrupter-Switcher Installation thing which will require some difficult debugging to get working, I decided to build something really quick & easy that was sure to work. Better that than give up electronics!

Inspired by PHOBoS' discovery that the flickering LEDs in dollar-store electronic tea candles make sound, I wired 3 of them up and sent the sound to a speaker, putting the whole lot in a wooden tea box. There's a volume knob and a switch to turn the speaker off, and tap wires for a line out.

A quick demo can be seen here: http://youtu.be/GE7RyhDhcyo

what a lovely box Very Happy

.

but to be faiir it's not my discovery, I think I got the idea from here.
But I had not seen them used in a lunetta before.

And is it just me or does it sound like they are communicating/arguing with eachother

. I was actually
working on a circuit to make them 'listen' to eachother and respond, involving a shiftregister. Which is why I started
with them in my modular lunetta. Cool

(to save breadboard space)

That tea-box-fickering-candle thing is brilliant Laughing

the sound makes me laugh, it just sounds so silly! but very effective Smile

Dollarama ftw! I picked up a cool LED-based strobe light thingy from there a while back. They're also handy for wooden enclosures for lunettas. And a million other things of course.

most likely the last one for this year: a custom build of a dual QuadSequentialSwitch...

Love the 2xQuadSeqSwitch! Great looking panel. Tidy build behind the panel, too.

Last one of the year for me. And going out on a festive note!

I've had these pcbs for something like 4 years. Got started on the panel design 3 times, but finally finished it this time. It's a strange collection of knobs to try and make some kind of sense out of; maybe I got close.

That's gorgeous and you fit it into 2 wide! My notes had me for sure doing it in 3....

I really like the use of color to keep it straight.

Yes - I've seen 3, 4 and 5U versions, but they all seem kind of large for what this module does. I mean, it's a great module soundwise, super flexible, but you're going to want 2 or 3 of them, and you can't take up a whole cabinet for these things, can you?

I will say this - those knobs are awfully close together - it takes some dedication and care to tweak the inner ones without moving the ones around it.

awesome sduck! - i think lars also made one in 2u

i have populated my pcbs but waiting to case up my mb808 before i begin on another drum machine

I like that a lot. I can see your panel designs creeping away from MOTM.......

I'm not so sure I like the diagonal set up or the colored knobs, sduck, but I really like your approach. I've avoided buying that PCBs because of the panel real estate required. But you've shown it can be done in a reasonable amount of space. So kudos!

very nice layout sduck as always
I have 3 MPS's to do panels for soon, i think i will do something along similar lines . my panels are a little larger at 241mm high x 100mm wide though which should help a bit those knobs do look a little too close for my fat fingers Smile

The Sweet32 Speaker Interrupter-Switcher Installation Thing

After a few years of collecting speakers from stuff found in the trash, I finally got them off the floor and onto the wall. There are 47 speakers per panel, but only 16 per panel are wired up to the control box. The box takes a 2 channel input and randomly selects which of the speakers the sound is directed to (for each panel). The rate can be controlled by the knob, or via an external CV. There is also the optional interruption control on a per-channel basis... this cuts the sound going to a panel according to the rate set via the knob (or external CV). Alas, the box and the speakers are not very clean-sounding, so not just any audio is suitable. It is best to feed it with simple drone oscillators.

No video could really demonstrate what this installation sounds like in person, with the sound moving around. If you're in Montreal, Canada, maybe we could arrange a visit...

An automatic drone box for use with this thing is possibly in the works....

I've lost count of how many hours this thing took to make. I must be insane.

James.
