This section is currently being built. I working on some circuits which I will post online for free download. There is one project I think may become popular but I need to work out some engineering details. Basically Synthesizers from the 70's and 80's had a sound engine based on VCOs or DCOs (Voltage/Digital Control oscillators). Lately I have been thinking of LCO's (Laser Control Oscillators). Laser frequency or wavelenghs are way too high to hear so why not modulate the light at lower frequencies by mechanical filters or by modulating the laser's power source affecting it's output. The output signal would ride on top of the laser signal producing the audio signals. The mixer could consist of prisms which will allow the two LCO's to combine creating an Interference pattern. The ADSR for the amplifier can be modified by either changing the intensity of the light from the power source or introducing two LCD filters to manually filter out the light's intensity which is the volume. The most complicated thing to do is how to crate the VCF functionality? If you turn the light back into into electrons and feed it through an transconductance OPAMP (Filter) then you are basically an Analog synthesizer. The final issue is how do you send the signal to the amplifer? Speakers require electron flow to create sound and not photons. Well its an idea to start with and hopefully I can comeup with some interesting results.
