gah, no sense of humor.

Quick method for regulating 12+ to 12v steady. There's a voltage drop off of around 1v or so. Using a 7505 or 7509, you can get regulated 5v or 9v too respectively.

Note: Less then 1 amp load. You cannot get regulated 3amps by just using 3 7512s or the like, so don't try.

Sends a momentary pulse to push the power button when the computer senses the charging go from cold to hot AND it's not already awake.

Enjoy!

Here is a switch configuration that let's you manually control your PSU. It works for ITPS, Opus, and CarNetix type PSUs.

Heres the pinout for your normal DB25 printer cable to use for wiring up HD44780 type LCD's

These circiuts you may find usefull to "trick" a motherboard into powering up just after it has recieved batt power thru an ignition relay and a "on pulse" is needed to fire up the atx motherboard connection. There are plenty of other uses for them if you can think of them. Such as dethump power dissconection of amps during head unit turn on, etc.
