Active-Matrix LCD Bias Supply Operates from Battery Input - 02/03/00 EDN-Design
Ideas.....Many active-matrix-LCD applications need multiple voltages for
thin-film-transistor (TFT]bias. Typically, three voltages are necessary 5V for
column driver; a positive voltage, such as 10V; and a negative voltage, such -5V, for
TFT gate drive, or row driver. For handheld electronic devices, a battery must.....

Audio noise generator drives earphones or small speaker - This is a circuit
that generates white noise, rolled-off to drive earphones or a small speaker. White
noise creates is a "rushing" sound, which sounds something like air rushing by your
ear(s). White noise would be flat with frequency, and since this circuit rolls off
within the audio range, I refer to it as "rolled-off" noise. White (or rolled-off)

AVR 2x16 LCD & 4x4 keypad driver - A very simple circuit to experiment with
AT90S2313, 2x16 LCD display and 4x4 keypad. The clock based on 4 MHz crystal, but you
can use anyone crystal between 1-4 MHz. The keys with the name "A", "B"....."F" are
typed to the LCD with numbers 10-16. Because the AVR have only 15 I/O pins we are
working the LCD display with 4-bit databus. The 4 resistors (10K) are to protect the
AVR from the shortcuts as the coloumn of the keypad is change.....(circuits added
