Chloroplast Voltage Controlled Solar Engine - Voltage-Controlled
Solar Engine: These designs are based on the Motorola MC34164-* micro
power undervoltage sensing ICs. They're pretty efficient, work at higher
voltages... |

Circuit Controls Stepper Motors - 01/08/04 EDN-Design
Ideas....Stepper motors are useful in many consumer, industrial, and
military applications. Some, such as personal-transportation systems,
require precise speed control. Stepper-motor controllers can be simple

Circuit forms DC-mmotor switch with brake - 10-Jan-02 Issue of EDN
Controlling a small dc motor without speed control sounds like a trivial
task; a switch or a relay should suffice. However, several problems
accompany this approach. For one, the switch, because of the inductive load
and the low starting resistance of the motor, tends to wear out prematurely
(with all the related sparks and EMI problems]....[Design Idea by JB Guiot,
DCS AG, Allschwil, Switzerland] |

Circuit Generates Analog Fan Speed Control - Maxim-IC Appnote
#1125 / (app note added 5/08) -This circuit delivers a continuous and linear
fan-control voltage that is proportional to temperature. |

Circuit generates fan-speed control - 21-Mar-02 Issue of EDN
Fan noise is becoming a significant issue as electronic equipment
increasingly enters the office and the home. Noise is proportional to fan
speed, and the airflow¡ªhence, fan speed¡ªnecessary for cooling is less at
low ambient temperatures. Because ambient temperature is lower than the
upper design point most of the time, a fan can run slower, making it easier
on the ears....[Design Idea by Jim Christensen, Maxim Integrated Products,

Circuit Measures Small Current in DC Servo Motor - 12/06/01 EDN-Design
Ideas....The simple Circuit design in Figure 1 lets you measure all components of a
current flowing in a dc servo motor. The rectified output of the circuit uses ground
as a reference, so you can measure the output by using a single-ended A/D converter.
The current-sense resistor, R1, has a value of 0.1Ω..../ (Circuit design added 11/06]

Circuit protects system from overheating - 8-Nov-01 Issue of EDN The
two-chip circuit in Figure 1 provides fan control and overtemperature warning and
shutdown signals to protect systems from excessive heat. The circuit monitors the
temperature of the pc board and the die temperature of a CPU, an FPGA, or another IC
with an on-chip temperature-sensing transistor....[Design Idea by Kerry Lacanette,
