(n) Modular Synth - The Envelope Generator
Now it's time to build the second module (PSU was first). I went for one of the smaller and easy to test/debug ones. Yes I am a pussy.


That's the PCB once more.


All parts mounted. Yay.


My ghetto test panel. Purty, isn't it?


This is how I plan to mount the PCBs to the panel. On modules without pots I am screwed, I guess.


PCB mounted to the ghetto panel and some of the wiring done.


And that's how I test stuff atm.

Turns out, the envelope works nicely and as expected. Hooray #2.

Some updates:


Now with the preliminary panel :-)

(n) Modular Synth - The PSU
The first module I assembled was naturally the PSU. Makes testing a lot easier if you have power ;-)


This, again, is the bare PCB for the PSU.


That's the assembled PSU. You think the heatsinks will be big enough? ;-)


Top-down view of the PSU, the two power LEDs (one per rail) are not yet connected. Duh.


The fused mains socket and switch. All nicely isolated because I don't really like electrocuting myself. 230VAC is ouchy.


And that's the whole thing with the transformer. Done.

Tested and working nicely. Phew. that's a good start. Let's hope the rest works out as well.

(n) Modular Synth - Ready, Set, Go!
I'll document the building of my modular synth here. It's mainly going to be pictures, because I am too lazy to type.


Sooo, the parts and PCBs got here. This is one of the three boxes of parts I got. All the parts were ordered from reichelt, musikding and farnell. I got the the knobs off ebay.


This is the pile of parts. Thank god reichelt (where I got most of the parts) ship all the different values in different bags. Conrad has a tendency to just throw all the stuff into a box....


That's the PCB which contains 9 modules. Yes, it's missing the part names, because I am an idiot :-)


And that's the PCBs after I cut the up with a handsaw.


All of them have my logo, teehee.

Moving on to the different modules:

The PSU. +-15V regulated at ~1A.


A headphone amp. Always handy.


An envelope generator.


VCA with uni-/bipolar option.


Steiner VCF, bwowowowow.


MIDIbox CV + aout_ng + DIN module. My MIDI2CV module. More info on it can be found at http://www.ucapps.de and http://www.midibox.org


The VCO, would suck not to have one, eh? Why did I take this pic with the PCB turned 180? Dunno.


An LFO. Can you ever have enough CV sources?


And that's a mixer. Whee.

Well that's the PCBs. Next up: Assembling and testing them.

This is a picture of the prototype taken with my webcam. Sorry for the lousy quality; higher resolution pictures will follow soon.

Here we go - better pictures:

Commenting - it is allowed you know.

theGIMMICK - pic-based DIY guitar tuner
Whee! Fresh project, just finished :-)

theGIMMICK is a DIY PIC16F84A-based chromatic guitar tuner. The PCB is roughly 40x60mm so the whole thing can be built into a regular sized stomp box.

A mockup of how it could (and will as soon as I get the case delivered) look in a stomp-box case:
