via Axehole: Experimentalist Anonymous has posted a journal of building a modular synth in a month.

“During the month of January, 2006, I built an analog modular synthesizer from the ground up. At Oberlin, where I go to school, January is a time for students to work on individual projects of their choice. It has always been a dream of mine to build a modular synth, as I not only wanted one but also thought of it as sort of the “next step” after pedal building. I started on January 4th and ended on Febuary 4th (at 2 in the morning no less!), so it really did take a month to build.”

There are currently 12 modules in the synth, as follows (from left to right):

• Voltage Controlled Oscillator 1
• Voltage Controlled Oscillator 2
• Dual Logarithmic/Linear Voltage Controlled Amplifier
• Dual Low Frequency Oscillator
• Attack, Decay, Sustain, Release Generator 1
• Attack, Decay, Sustain, Release Generator 2
• Voltage Controlled State Variable Filter
• Sample and Hold and White Noise Generator
• Dual DC Mixer
• Triple Guitar Interface
• Voltage Controlled Lowpass Filter
• Power Supply/Switch

Total price: $785.15

Pretty impressive DIY project for one month!
