Thats the best style of all, because it means you are probably putting function over form
It is the pervading law of all things organic and inorganic,
Of all things physical and metaphysical,
Of all things human and all things super-human,
Of all true manifestations of the head,
Of the heart, of the soul,
That the life is recognizable in its expression,
That form ever follows function. This is the law.
I love that they all have a different look. That's one way to differentiate functions.
You might need to eventually do something about the top sagging of the 2nd unit from the top. _________________ Revenge is a dish best served with a fork... to the eye
Finished L-1's Quad VCA, sounds awesome!
I used TL074s, OPA2604s (from ebay), and (2)2180As and (2)2180Bs. I applied L-1's suggestions (thanks again) for adapting to banana plugs, works fantastic!
thanks cyno! i did the layout in photoshop but the artwork is done by an artist named Raymond Pettibon. The text in the corner reads "I want the girl in the wig commercial" haha
This is the first finished module of the new rack I built. I'm using the lamination technique and am going for more colorful, artful panels. _________________ http://www.youtube.com/user/borisandfef
Wow Fonik - that's some amazing stuff! I also have dual wogglebug - once you have 2 one is never enough. And that stepped filter thing looks very very tempting - is the pcb available for that, or is it a bunch of stuff cobbled together?
Just finished this -
David Dixon (AKA Dr. Sketch-n-etch on Muffwiggler) supplied me with a hand etched pcb, and some wiring ideas, and this is what happened.
And that stepped filter thing looks very very tempting - is the pcb available for that, or is it a bunch of stuff cobbled together?
it is basically eight (8!) sem style multimode VCF PCBs, and a controlle board containing a sequential switch and a stereo mixer.
i am currently working on a smaller 4 filter version, everything on one PCB, and using VCAs instead of analog switches to eliminate the "pop":

Except in the commercial modular synth world, where you are strictly constrained by size restrictions, knob type, panel graphic style, you name it. All modular manfacturers force you to change your design/features.

I'd say it applies to the DIY world as well. I have a 5U system, and leaving large blank spaces on a panel seems criminal. So I often find myself adding or deleting features based on the panel layout.
Last night a friend was showing me a pcb layout he's working on. I asked him where the front panel design was. He said he hadn't really thought about yet. I told him he was putting the cart before the horse - without a front panel, how could he know what features to include, or how many copies of the circuit are needed? :( Luckily he saw the error of his ways and is now working on a panel layout. :)

That's why I've never used modules. Everything goes behind 19" rack panels. Then you just have to scrunch things up a bit or spread them out to make all your features fit. Form following function.

Megatron Subject description: Modified Korg Monotron
My goal with this project was to create a MIDI and voltage controlled bass synth similar to the Minitaur, Mopho and Microcon, while keeping the ribbon control from the Monotron.
Mods include:
-MIDI-IF kit
-CV control
-Pulse Wave (with PWM, high-pass filter and low-pass filter)
-Sub Osc 1 (one octave down) with low-pass filter
-Sub Osc 2 (2 octaves down) with low-pass filter
-AD Envelope
-Overdrive feedback loop.

That's what I'm doing on my first several panels. Thing is with that, it really multiplies the amount of time and effort you have to put into PCB choice and their order on the panel, as you can't later decide to move the individual pieces around once they're behind a big honking panel.
So pre-planning and certainty becomes critical.
"Form follows function", though, does not mean you grow your panels to fit all functions possible. Design of anything is always a process of tradeoffs and compromises between functionality, available/practical size and cost.
Limiting what functions you include on a panel is simply part of the selection process in determining Function in the Form vs Function equation.
Classic example: the Minimoog. There are definitely functional tradeoffs going on in its design.:
*No random access to waveforms (you have to select waves from a rotary switch moving from one to the next until you get to the one you want).
*Mixing of one oscillator's waveforms to create a hybrid a waveform is not possible (ARP, OTOH, had mixers on even its AXXE synths so you could blend triangle and pulse together)
*Only VCO 3 could be used as a modulation source.
*Signal routing was hardwired VCO=>VCF=>VCA with no ability to alter this with patch cords (like the Korg MS series allowed, or the ARP 2600)
And so on. But after that selection of functionality was set in stone, the Form of the Mini is obviously well thought out and serves to maximize Functionality.

Here's a Thomas Henry SN-Voice I had kicking around with no panel for a while, I finally made up a panel and wired it last week over the bank holiday weekend. It worked on power up, so that was a good thing.
