Found: a homebrew modular synth.
Dave Wright found this at a “junk shop” in Tucson. It uses two CEM 3394 chips, plus a PAIA MIDI-CV and a few assorted circuits. It was very well-made, almost commercial quality. The maker’s identity is a total mystery.

Some of the crazy at gieskes.nl:
First, the “Acid Machine”, which generates pitches with a rotating wheel and LDR.
Plus, the Synth-Fan, doing similar business with a small computer fan.
And this, whatever it is.

goes into a 6au6 via depth/drive knob with a neon as a modulator –
inductor on the plate for tone
goes into a second 6au6 via depth/drive knob and neon as modulator

6AL7 magic eye on the outputs
each modulator has rate knob and ‘range’ switch – one setting being
a .015 cap across the neons – the other setting being no cap between the neons
some how this works really nicely
you know i couldn’t do it without barbour’s help!!!

Unearthed Circuits
They build some damn impressive gadgets…..that do something.
And how often do you get to read about Paul Ketoff and his notorious Syn-Ket?
Not to mention its predecessor, the Fonosynth. Yet another great unsung pioneer of music synthesis.
Who is this guy??
Retrosonik is primitive and looks like it was abandoned years ago, some of the links are busted and there isn’t any information in Whois except the name James Phillips. I must say, his projects are amazing, what little we can see of them. (Although his spelling is awful.)
Want to explore alternate tunings? Now it’s easy.

H-Pi has released a new, updated version of their Tuning Box. It does any arbitrary tuning setup, from Archytas Septimal to Just to Harry Partch’s 43-Tone Chromelodeon Scale to Johnston Enharmonic. You name it, if your MIDI synthesizer accepts pitch bend, this device ($299 is an amazing price) will generate the correct MIDI messages to make any alternate tuning or key reassignment desired. I’ve already ordered one for my own experimentation.
—————————
H-Pi also had something on its website that amused me.
Remember my post about unusual MIDI controllers last March? Well……
The New York Times ran a strangely familiar article four months later…..
TUIST

Clever fellow made a controller with no keys, strings, or gizmos to trigger. You play it by tilting, rubbing, squeezing, shaking, etc……
Wired magazine article here, Gearwire video here, his website is here. Hope he manages to get it manufactured in some form.

The Brutal Blinky
A synth made of neon lamps, from Not Breathing.
Videos of the Blinky in action: 1, 2

Quote from the maker:
5 neons in a ring counter type set up with a pot and cap value change for each stage,
a multivibrator modulator w/ 2 neons – rate pot, shape pot – range switch, switch o/off to ring counter.
different one w/out shape pot or range switch – depth pot – switch to power it from b+ or the previous multivibrator and switch on/off to the ring counter.
a third single neon osc as modulator w/ just rate pot, switch from b+ or previous modulator, on/off to ring counter
subosc divider, i grabbed from your vco circuit i believe, w/ a range switch,
and a 12 stage passive low pass filter (the magic part)
“Oceanus”
A great British DIY circuit-bender. A few of his gadgets have been mentioned on Matrix before, but I just want to direct you to his YouTube page. He doesn’t seem to have a regular web page. Unlike most other circuit-benders, Paul takes great care to make his gadgets look good, as well as sound interesting.
!! SKANKULATOR !!

From the YouTube video:
“6 oscs(cmos), 4 ring mods(cmos), passive vca(diodes), passive vcf(vactrol), decay generator, additional passive low pass filter (via rotary), 2 watt amp – some knobs n crap – a lunetta? the vca modulation is skankulation – i have a lil fet s&h between the 6th osc and the vca – no buffer not so good”
No doubt, gear makers have horrible nightmares about people like this:
Don’t tell PETA!!
sorry for the quiet time
Not many people have been posting to DS lately. So let me fill in with a new photo–this is the first of the Eurorack modules that Metasonix will introduce in 2009. First one is a combined tube distortion/VCA, using variable-mu pentodes (26A6s to be specific). Shown here is the first prototype. I’ve built 2 more, and they all work exactly alike, so it’s a solid and reliable design. Hopefully it will be ready to show at NAMM.
Infernal Noise Machine v1.1
Six months later (original post):
The picture is of the v1.0. The v1.0 used an out-of-production case, the v1.1 is in a slightly different housing.
I am doing a limited run of five of the v1.1. Each unit is completely hand-made and is personalized on the jack panel. The I.N.M. is the flagship of our semi-pro gear, and is intended for studio use. More information at >the I.N.M. page<.

“How to make a Phantastron sing” article

I posted a brief article on phantastrons and how to use them in audio synthesis on my Weblog at
http://www.electricwestern.com/
Yes, there are schematics posted for the truly insane, and some suggestions to get you going. I was truly sad when I discovered that there really isn’t much info available on that great circuit of WWII radar!
Enjoy, and if you REALLY love it, you can feed me by getting a kit :). Maybe I’ll even cut you a deal or a swap if you’re a sufficiently deviant synther…
And, if you don’t already know, Electron-Tube Circuits by Samuel Seely and other old technical books are now in the public domain, and can be gotten at http://www.pmillett.com/technical_books_online.htm
Now, go forth and study! And do make something really tweaked, please.
Phantastron Kit Available
Electric Western is proud to present the Phantastron Kit: an all tube synth kit. The first all tube synthesizer extracted from Navy radar circuitry (at least that’s where I got it).
Here’s my video of testing the prototype model (yours will be prettier and sturdier) Audio starts as the tubes warm up (within 25 seconds) –
Video Demonstration:

Phantastron Under Test
First, I’ll start with what you don’t get:
1. A metasonix oscillator (yes it uses a 2d21 thyratron, and yes, I too love metasonix and Eric’s work, but this thing is different – the last thing I want to do is rip off someone else, really). But thank you Eric for introducing me to the 2D21, it does work better than the 884 in this case (although the 884 is sooo sexy looking)
2. 1V / xxx — the CV is quite variable, which makes this intstrument, well more like a trautonium than a TB303. Just watch the video above and know that the ribbon controls 0 to 5.5VDC linearly.
NOW, WHAT YOU DO GET:
A Turret board with extra turrets for your own mods.
All the electronic parts, including a 2D21/PL21 thyratron and a 6SJ7 Pentode. Why these tubes? Well, the 2D21 is the most affordable thyratron and the 6SJ7 is a metal wonder that is RESONANT as heck in a phantastron circuit.
An all wooden box and 1/8″ Steel panels. Copper, brass and other shiny things.
A completed, safe power supply which reduces the possibility of tasering yourself and eliminates the possibility of working directly with AC wall current.
Instructions with theory lessons and the original scans of navy and pre-WWII tube textbooks. Drawings and and assembly guides. A nice note from me and my wax seal (yes, I am steampunk, and I do write the note with a quill pen on artisan paper).
All the fun of tubes and experimentation without buying metalworking tools, having a workshop, etc.
Oh, and please buy one, they’re pretty cheap, awesome, and I quit my job as an audio electronics professor and corporate employee to make more crazy stuff. The pitch ribbon is the next release, but if you’re really anxious, you can get a 500mm strip from SpectraSymbol at Spark Fun electronics and make your own. Or I can show you how to make one from $5 worth of EM shielding plastic and mylar. The Electric Western one will include some logic to change tuning, allow two touch finger control, analog computing and sustainable local lumber, etc.
Also, we are total “western steampunk”, post-apocolyptic mountain folk, and we use no lead, local materials, wind our own coils, never get Chinese circuit boards, use “green” canadian lumber and have a solar power array that makes 5KwH a day (and a steam engine that makes abut 9 watts), catch and use rainwater and live in an earthship, compost all of our feces and urine into bio-gas and humanure. And I really do wear a cowboy hat and I’ve punched a goat (lovingly). So, just buy one (a Phantastron kit, not a goat) to support our carbon neutral anti-corporate lifestyle (if that’s your thing).
Or just buy one and return it if you’re not happy. I can deal with that too. But you will be happy.
Here’s a time-lapse video of soldering the turret board: http://www.youtube.com/watch?v=eoEjkSMbkDM
Oh, and thank you to Eric and Metasonix for opening up the world to crazy tube instruments!
