A Stereo Digital Volume Control based on the CS3310 - The CS3310
is a complete stereo digital volume control designed specifically for
audio systems. It features a 16-bit serial interface that controls two
independent, lowdistortion audio channels. The CS3310 includes an array of
well-matched resistors and a low noise active output stage....(data sheet

A worked Stepping Motor Example - Perhaps some of the most
commonly available stepping motors, for the experimenter, are the head
positioning motors from old diskette drives. These can be found at
electronics swap meets, in computer surplus outlets, and even in trash
dumpsters. In addition to a stepper, a typical full-height 5.25 inch disk
drive includes a 12 volt DC motor with tachometer....(Circuit design added

ADC controls multiple stepper-motors - 09/14/00 EDN-Design
Ideas....Typical stepper-motor control circuits use either logic gates and
flip-flops or shift registers to generate the proper sequences of binary
codes that produce bidirectional stepper-motor movement. A conventional
stepper-motor-control circuit uses a square-wave generato....[Design Idea by

Adjustable Voltage Motor Controller - One of the nice things about
flying electric is you can test run your motor in the house, workshop, or in
the yard and the neighbors won't complain. The problem is how to control the
speed of the motor. One way is to use the plane, radio, and speed control
with the motor in it. That's no fun!....(electronic circuit added 4/05)

Alternating CW & CCW Motor Driver - A while back a company needed a motor
controller for a custom door latching system. The system used a small brush
motor with a speed reduction gear to both latch and unlatch the door. When
pulsed for about 250ms in the clockwise direction, the motor would unlatch the door.
When spun in the opposite direction for 250ms, it would latch the door. The circuit
below performs this function. A single low power pushbutton is used to alternate
between the two directions. The circuit is powered by 4.5v using a battery made
from three alkaline AA cells. The motor draws about 250ma. The battery should
provide many years of service. [Designed by David A. Johnson] |
