Desktop Power Supply -  (application / block diagram added 6/07)
Desktop Power Supply Clone Market -  (application / block diagram added 6/07)
Digital Speed Control -  Digital Speed Control with aSwitching rate of 15KHz (circuit added 11/06)
Digital Speed Control for RC Car -  DC motor PWM controller that takes the1ms to2ms pulse from the RC receiver and converts it into a PWM train at1Khz (added 5/02)
Digital Speed Control with Reverse -  (Schematic added 11/06)
Dimmer/Motor Speed Control -  Lamp dimmers using traics can be quite simple,  nothing more than a potentiometer, resistor, capacitor and triac with a built-in diac. (See Teccor's application note for examples and other technical data.) The circuit below is similar....(electronic circuit added 7/03)
Discrete component motor direction controller -  This circuit can control a small DC motor, like the one in a tape recorder. When both the points A & B are "HIGH" Q1 and Q2 are in saturation. Hence the bases of Q3 to Q6 are grounded. Hence Q3,Q5 are OFF and Q4,Q6 are ON .....
DMOS 3A, 55V, H-Bridge -  National Semiconductor Application Note....[App Note]
Dremel Speed -  The circuit at right uses a logi-level N-channel FET driven directly by the PIC.  The PIC creates a variable PWM signal to power the  motor.  Motor current is sensed using a combined 0.5 ohm resitance to ground.  Since this …. [Luhan Monat - Mesa Arizona]
[_OLD-ads-dont_upload/OLD I-ADS from web/ad-djandassoc.htm]
Driving a relay with a CPU -  ASCII format (circuit added 2/07)
Driving Bipolar Stepper Motors  -  The permanent magnet rotor has the same number of pole pairs as the stator coil section. Interaction between the rotor and stator (opposite poles attracting and like poles repelling) causes the rotor to move ¼ of a pole pitch per winding polarity change. Motors are available in either 2 coil (bipolar) or 4 coil (unipolar) windings. In the unipolar  ….(design added 11/08)
DS1821 programmable thermostat -  (diagram added 2/07)
DSSSE: Dual Slope-Sampling Solar Engine -  Voltage-Controlled Solar Engine: The dual slope sensing SE is another Wilf Rigter design; this SE is optimized for 'bots with a low-power standby mode.  (added 11/05)
Dual Channel Servo Pulse to H-Bridge Interface -  (circuit / schematic design added 7/06)
Dual Channel Servo Pulse to H-Bridge Interface ~mixos -  (electronic circuit added 2/07)
Dual DC Motor Speed Controllers Navigate Robots -  03/29/01 EDN-Design Ideas....Mobile robots need simple and lightweight dc-motor-speed-control hardware that can work with low-power batteries. Flip-flop type navigation systems allow only one motor to operate at a time while the other motor remains off. Navigation direction changes....[Design Idea by Shyam Sunder Tiwari, Robotics Software Pvt Ltd, Gwalior, India]
Dual Fan Controller -  Each fan turns off when the temperature drops 5 degrees below its turn-on temperature. For example, if the dial is set to 80 degrees, the fan turns on at 80 degrees and turns off at 75 degrees.  This prevents the fan from cycling on and off rapidly, which would occur if the fan turned on at 80, started to cool the cabinet, and then immediately turned off at 79. ….(design added 11/08)
Dual Fan Controller (David Cook) -  A birthday present gone too far. An overengineered temperature-based automatic twin fan controller with brass face to keep a kitchen PC cool.  (project added 11/06)
Dual Slope-Sampling Solar Engine -  Voltage-Controlled Solar Engine: The dual slope sensing SE is another Wilf Rigter design; this SE is optimized for 'bots with a low-power standby mode.  (added 11/05)
Dual Stepping Motor Drivers using UDN2540 -  In this design we use two UDN2540B to drive two stepping motors at the same speed. Each motor can be independently controlled. The S1, S2 switches control the ON/OFF and the moving direction of Motor1. The S3, S4 control the Motor2, respectively....(electronic circuit added 4/05)
