| Atmel’s AVR450 reference board described in this article has just about everything you would expect from a high-end multi-standard battery c...
| This programmer was specially designed for those of you requiring a cheap way to program PIC microcontrollers, without sacrificing useful fe...
| The IMT902 from Nanotec is a PWM chopper type sinusoidal microstep bipolar stepper motor driver. Two stepper motors can be controlled by a s...
| A simple proportional fan controller can be built using the MIC502 from Micrel (www.micrel.com). With this IC the speed of the fan runs slow...
| This circuit, aimed at electronic and power electrical engineers, is a test and simulation instrument for ambitious experiments. In combinat...
| Pulse width modulation (PWM) is Ideal for controlling small electric PCB drills that draw currents of up to 2 A. Larger currents are poss...
| The most remarkable feature of this small stereo amplifier is the use of a stepper motor bridge driver IC as a stereo power output stage....
