finally wiring this baby up
check it
this is about the only module i have without mods or extra circuitry
but i did include input attenuators for every cv input

dual phase distortion vclfo (tom wiltshire edruid / haxster)
For a long time i have wanted to build the electric druid vclfo (http://www.electricdruid.net/index.php?page=projects.lfo9) but i didnt really have the knowledge to implement it exactly how i wanted it. Luckily haxster came along with a pcb on electro-music.
This module is a digitial lfo with various features, first one being voltage control, second being phase distortion (ala casio CZ), third being lots of waveforms selectable by CV and more.
There are a couple of pcbs for this module now but no one has really made all the good parts accessable so i have had to really mod the hell out of the haxster board to get it to near where i want it.
The haxster version had the edruide vclfo core with external VC but nothing else. He included 2 extra lfos which is handy. I have added VC for phase distortion, waveform select and S/H rate. Haxster for some weird reason has 4 buffered outputs from the vclfo so i hacked the pcb so that instead of buffers the opamps actually run as led drivers for the analog lfos. So far i have drilled lots of holes in the pcb, have wires running everywhere and it is only going to get more crazy as i get closer to completion
I seem to be stuck on some stupid problems in the analog lfo, the vclfo works. I havent tested my mods yet as i want to fix these silly analog lfos first. Getting close.

uncertainty
i am working on another module
this is a combination of the bunchla source of uncertainty and ian fritz's chaquo
i have used 3 of the 4 SOU pcbs, i skipped the sample & hold / integrator pcb
this module has the following functions:
quantised random voltages
stored random voltages
fluctuating random voltages / stepped output
noise source (original digital MM5837 ver and analog tranistor version selectable on panel)
quadrature sine osc
double well chaos generator
i have populated the SOU boards, just waiting for the rare MM5837 chip to arrive
and i should get my Chaquo pcb in the next few weeks
it is going to be a challenge to get all these pcbs mounted behind the 2U panel :)
