2012 Build Pictures

The sound quality from my camera is TERRIBLE, but this module only does control signals.

This is a prototype I finished yesterday, it's a voltage to rhythm converter. It does an ADC on an input voltage and uses the binary result as an 8 beat pattern. 8 different outputs can each correspond to a different sample, or it can be put in parallel mode and each output corresponds to a certain bit of the same sample. It can output triggers or gates, has a built in clock or can run off an external clock. I've had a lot of fun with it over the last couple of days!

The Clockbox... not really a soundbox, this is more of a small utility device for making breadboarding Lunetta test circuits simpler. I thought it was kindof pretty, so I post it here.

I got tired of building power sections and clock oscillators over and over, so I built this little box that gives me a regulated and filtered 9V and four square wave clocks. Each oscillator has 3 different range capacitors, so the box can produce frequencies ranging from about 0.01 Hz to 6300 Hz overall. With some alligator clips and/or wires into the salvaged speaker terminals, I can plug it into my breadboard and away I go!

Despite careful planning of some stuff, I didn't realize that all this stuff in such a small box would barely fit... in fact, I had to glue the thing shut... hopefully I'll never have to get in there to fix anything! Oh well, each build is a learning experience....

Very nice. I like the salvaged speaker connectors.

I built a half a dozen modules including:
5U E340 Cloud Generator
5U E350 Morphing Terrarium
Threeler Third Order VCF
Buchla Pulser - Crossfader - Timbre Generator
Tap Tempo LFO
XY CV controlled Laser

RingMad, your box building skills are improving! Great little utility box you got there, not unlike my emSynth clock modules in purpose though totally different in form. And hey, diversity is our strength, right? Rock on RingMad!!!

..,and yesterday I finished my WogglebugXL Very Happy

It's based on Richard Brewster's version, with some extra in- & outputs
and adjusted to -5/+5V levels, except for the clk rate CV, which is now buggin me a bit (you get it 'buggin'

, sorry that was really bad)
so i'll probably change that sometime.

Wow, lots of cool projects out here! Does give me some feelin to start again myself, after a few months.

Your boxes look amazing Phobos! Very Happy

Amazing work Phobos!

That looks rad, Phobos. I like the blue transformer.

Here is a look at the second emSynth test circuit that I have built. It has three oscillators in the background and two ringmods in the foreground, plust a stereo out at left. See www.emsynth.com for details.

Thanks folks. Yeah, the speaker connectors... I was originally going to use bolts, like I've done on 2 other boxes, but it would have forced me to use alligator clips only. And then I realized that hardware already existed for this situation, and would allow using gators or wires. To the salvage box!

I'm happy about the dark metallic green-blue paint job, although it was really hard to photograph accurately.

PHoBos: You're a monster! So prolific with the great-looking boxes!

davebr: That laser thing looks amazing!

Les: Rock on! I don't know how you do it, soldering that tiny stuff! Do you use one of those magnifying lamps? At my age, I'm having trouble seeing close now.

James, I am one of those strongly nearsighted people (20/400 vision) that is somewhat blessed or fortunate in that without glasses I see tiny objects with great clarity - if they are positioned about 4" to 12" from my eyes.

Naturally, soldering without safety glasses is a concern so I plan to get some type of clear or slightly magnifying glasses if only for safety's sake.

And the tiny parts are not that amazingly tiny, I was soldering 0805 and SOIC parts in the late '80s and early `90s when I was working. The tiniest thing I ever soldered was an 8-bump 555 flip chip, to which I soldered a wire to one corner pin. At this stage in life, though, I don't think I'd feel safe soldering anything smaller than 0805 discretes and SOIC chips.

But you know what? those modules really save a LOT of space!I I didn't realize that 50% to 75% space savings depending on the board adds up to SO MUCH circuit density! Plus they are so easy to wire up. We'll, I should stop this for being accused of selling all the time, but hey, I'm proud of my little creations.

See ya round the forum,

Les

Here's the story so far; Suitcase Synth and the Behemoth. Just a few more modules to go...

Sorry if I sound like a bit of a tw@t saying "great for you doing this, BUT I have.....". It just came out a bit wrong

just a 3x3 matrix mixer. with zebrawood knobs, which i thought came out cool.

I like the woodwork! How did you attach those wooden knobs to the pot shafts? I've thought about making glass knobs for a build, but cannot think of a secure way to attach them other than glue, which would definitely make it hard to maintain...
