Next update on PCBs

I just got a delivery from Canada ..
2 BatteryAcid Distortion Modules from hexinverter
One simple and one with CV .. those where designed for the "I dream of wires" Documentary.

I also managed to solder the last parts of the first TH-102 VCO from MagicSmoke ... soon Panel mounting will be done :D

And I build a Cacophonator 6DE from Famfest for my two french Friends from the Cacophoneuses

TODO's 2013

I thought I'd do a quick reminder to myself which PCB's I've bought and still have to solder.

  • Dual Balanced Modulator (Ringmodulator)
  • Random Module (Noise / S&H)
  • VC Quadrature LFO
  • EMS Filter
  • Wavefolder (second PCB)
  • CV Standards
  • Klee Sequencer
  • Mega Percussion Synth
Magic Smoke Electronics:
  • Thomas Henry XR-VCO (2 Boards)
  • Single Bus Keyboard
  • 16 Step Sequencer with Vari-Clock
  • Tube VCA (two PCB's) 
  • Serge VCS
  • SubOscillator
  • Sequential Switch
  • Thomas Henry Controller LFO (2 boards)
  • MCV Interface (Midi2CV based on an ATMega88) (second PCB)

curetronic VCA done

did I already mention that it's getting colder outside??

I finished my second module today (PCB's where pre-soldered so actually this was just cabling/wiring)
It's the curetronic VCA => it can do linear and exponential, AC and DC and also offers 2 more inputs as an option.
I will add those two inputs on a separate front-panel with another multiple.

curetronic ADSR done :-)

It must be getting cold outside - soldering goes well.

Today I finished the curetronic ADSR(T) in addition to the typical stuff it has an inverse-out and a TIME-pot - we will see what it does :-)

Midi2CV done

Jet another board lying around undone is finished.
It's from a sequencer.de user named nordcore who did this thingy based on an AMTEL88.

It offers:
  • 4 CV (Tune, Velocity, Mod-wheel and Pitchbend)
  • 4 Gate
  • Start/Stop for Sequencers
  • Clock out and a Clock-divider
It can be used on one Midichannel, 2 Channel (2CV/2Gate) or 4 Channel (CV/Gate)
The CV and Gate can be configured with an CTRLR based userinterface.
The documentation is absolutely fabulous and all can be soldered within a couple of hours with ease.

If you are interested in the paneldesign I did, download it here
Finishing this module is another big breakthrough this week (the VCO is the first) => from now I can PLAY the modular (or Renoise, or Qmidiarp does)

CGS49 Twin CMOS Filter done

another soldered board that had been lying around without been put to the frontpanel.
The CatGirlSynth49 Twin CMOS Filter with J. Haible Distortion ....

The frequency pot has to be soldered between +15V and -15V (like described in the texts and schematics Ken provides) and I modded the resonance on one of the circuits like described on electro-music.com ...
will do some more tests tomorrow ..

Thanks to Ken Stoner for his nice DIY-boards :-)
