My homemade modular synth

Just wanted to share with everyone. Attached is an image of my homemade, Eurorack-sized modular.

It uses two Thomas Henry 555 VCOs with Fonik-printed PCBs. It has a two audio signal, two CV VCA inspired from this article: http://www.soundonsound.com/sos/jan00/articles/synthsecrets.htm

It has a filter with cutoff, resonance, and LFO modulation inspired and adapted from Music From Outer Space.

It has an 8 step sequencer inspired from this design, http://electro-music.com/forum/phpbb-files/thumbs/t_16_step_4017_247.png and modified with the help of PhoBOs

It has an LFO with square, sine, and triangle, and two "weird" outputs based on the 3 741s design, http://electro-music.com/forum/phpbb-files/thumbs/t_741lfo_169.jpg

It has a gate-producing module that is timed by a Schmitt Trigger and uses a 4024 to subdivide the pulses

It has a 555 timer in mod-able monostable mode that sends out pulses for temporary duration of time (button triggered)

And, lastly it has a mixer inspired from Bernie Hutchins' writing in Electronotes.

Panels are printed by Ponoko and Canal Street Plastics.

And all this has taken me since January of 2014 to build. Case was bought from Control in Williamsburg with Make Noise power bus included. (I stained the case mahogany). I also have an Intellijel microScale.

Thanks to everyone on this board for help!

Some minimal drone tunes (unmastered) can be found here: (before sequencer was completed): https://soundcloud.com/tetracathedral/sets These were recorded with this synth onto Tascam 8 track tape.
