Module a month part 3: May

Hi all!
again I am too slow with building, but a module is finished and I'm happy with it. This time the Mankato VCF from Magic Smoke Electronics. As always with their PCBs I have had a few problems with cold joints, but in the end it was all good. I used a kit from Woody's Electronics and the module was finished within two hours. Time for a picture!

What does it do, and what makes this filter special? First of all it is a filter and has 8 outputs: 6, 12, 18 and 24dB/Octave and their inversions. Those outputs have a phase difference of 45 degrees, so mixing the signals gives interesting filter slopes. Secondly the filter can get in self oscillation and due to the phase differences, it is a quadrature oscillator. The frequency range is really large, so it does work as an LFO too!
After playing around with it a bit I have to say for phat bass sounds the 18dB/Octave output is really yummie! The quadrature mode will be used when I've finished the module of June: the Oakley Quad VCA.

Cheers,
Woody

    1. I use cheap plywood, about 3mm thick. 4 euros of plywood makes quite a lot of modules! :-D
