This uses 15VDC 2.5A PSU to power the myPSU board
Have added an LM7812 regulator chip to take down to 12V
The 15VDC goes straight into the LM8117T chip

Why
Cause with 12V there is 1.5-2V drop from 12V to 0-12Vadj so only can get around 10.5VDC max out

LM7812 TO-220 1.5A Voltage regulator (1-In, 2=Gnd, 3=Out)
0.33uF ceramic on input
0.1uf ceramic on output
