Power Supply schematics errata

Many thanks to Carlos - Colombia for point erros in the Power Supply schematics: The capacitor of -15V is marked with invese polarity. Both (15V and -15V) power suplies must have a small capacitor (i.e. 22uF) on their output as request on their datasheets).

Anyhow, it will be much better if scrap the current power supply and use this one:

All the power will be suplied by the USB.
