    DIY | LFO | PHOBoS | MFOS | Triangle | Square | Saw


    PHOBoS LFO's this is his description : The LFO's are actually what I started with made of a basic 2 opamp inverter/integrator configuration, with square and triangle outputs, similar to the MFOS supersimple LFO. It has a switch to select between saw/triangle/inverse saw and a 3rd output which you can mix between the square and triangle. Originally I made it with only one LED, attached to the mixed output, but you can never have enough blinky lights, so I added one to the square out aswell. I made 3 versions with different caps to get a total range of ± 0.5 sec. to 10 minutes. You could offcourse use a switch to select different caps and have the full range in 1 LFO. The 100nF cap attached to the voltage divider for the squarewave (non inverting input of U1b) is added to suppress voltage spikes.
