I just corrected a few errors in four of the circuits:
-Capacitors are no longer backwards on Inverter -Ground added to power section on 12V to 24V DC-DC converter -Power supply now includes note about using 120 ohm resistor instead of 240 ohm -Op amp pin polarity corrected on low voltage alarm
Yep, the circuit still sucks. One of these days I will get around to looking through the large inverter topic and picking a few good ones for inclusion on the circuits page.
