A Hackable 12-Channel Bidirectional Logic Level Shifter/Translator

This is a very hackable 12-channel logic level shifter/translator with a voltage regulator. This video demonstrates how it works. There's more detail here on my website at http://www.thefrankes.com/wp/?p=2557.

In this example, it's translating from 7.5V to 3.3V. In another example on the website, I've demonstrated the hackability by wiring it up to drive a 3.3V Nokia 5110 LCD, using five of the 12 channels as logic level translators. Channel two is wired directly to 3.3V for power, channel three is wired directly to ground, and the transistor on channel nine is turned so that the 5V signal controls the gate, which allows PWM control of the LED with full power from the regulator.
