About PIC MicroControllers - (electronic schematic / circuit added 4/02)

ABR-42019 / Calculating Frequency Setting Resistors when Using the ML4835 - Fairchild Application Notes / (app note added 6/06)

AC Line Powered LEDs - The circuit above illustrates powering a LED (or two) from the 120 volt AC line using a capacitor to drop the voltage and a small resistor to limit the inrush current. Since the capacitor must pass current in both directions, a small diode is connected in parallel with the LED to provide a path for the negative half cycle...(circuit added 06/07/08)

Accurate Digital LC Meter - Based on PIC16F84A microcontroller, 16x1 LCD and LM311 IC (circuit added 08/07/06)

Accurate Digital LC Meter  - Most accurate and simplest LC inductance / capacitance Meter that you will find. It allows you to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 900nF. The circuit uses an auto ranging system so that way you do not need to spend time to select the ranges manually. ….(electronic schematic added 11/08)
