MIDI Clocks Module

Applied a new program to the MIDI2CV module hardware and can now generate clock sources based on the MIDI clock.
Sending 5 different divisions on the digital outs, and generating sine waves from a stepped value table at 3 different periods on the PWM outs. The Sine LFOs are in the range of 0 to +5V. Assembly code for the PIC18F2431 is here. Audio sample using 2 of the clock outs and the sine across a 1/4 note here.

More DLP v2.0 Boards

After a long pause, the control board for the DLP VCO got printed, along with the top and bottom boards for the midi2cv unit. Now just need to wait for some back ordered blank panels and will be able to finish these two eurorack modules.

DLP v2.0 Boards Alive!

I've started migrating the DLP modules to eurorack format - v2.0! First is the oscillator, two voices on one 8hp board; the knobs will likely live on a 10hp panel.

The boards came back this week, and I finally had a chance to wire one up and verify that it's alive.

The Eurorack Saga Begins

After actively trying to avoid going down the rabbit hole, the igloo has finally acquired it's first 19" of Eurorack rails starting with one of the most basic of sound modules, TipTop's lovely BD909 (and Intellijel's Audio Interface II for quiet i/o) This certainly isn't the end of the DIY circuits, as all the Lil'Penguin circuits will likely get a Eurorack makeover. There will also be many other notable and destructive modules as the Eurorack universe is rich with awesomeness, and MakeNoise being quite noteworthy.

Sunday, September 28, 2014 and have been updated with a simple new design.

Aslo, we have made several tracks from the back catalogue of each available on Blizzard and Calibrated's SoundCloud accounts. Enjoy!
