Elektor Hacks: Symmetric voltages from MAX232

From Elektor 2008-7/8 (uk version p.57):
Gratis Symmetrical Opamp Supply Voltages[1].

This is interesting for analog/digital synth hybrid experiments, since
most simple circuits really need a proper symmetric powersupply, and
gives a standard serial port interface.

Another interesting one on p.125:
PR4401/02 off the Beaten Track
