Manual Oscillatoscope1a

::ABOUT
It can convert CV (and optional audio signals) into video and audio.
It works by changing the frequency of oscillators that are synced to a composite video sync generator.
The signal that is generated is output as audio on a mini jack connector, and as video on the RCA jack connector.

::STANDARTS

PAL seems to work on all devices i have tested it on.
NTSC works on everything i have tested it on, but in the standard mode it did not work on my video projector, so i added a extra mode that makes it work on my video projector.

the next time you power up it will start up in the mode that was last selected

- PAL hold left 12mm gray button during power up
- NTSC hold right 12mm gray button during power up
- NTSC (video projector hack) hold left 12mm white button during power up
