LED Flasher is a simple project producing a flashing effect of six LED’s.  This project can be used in all areas where you want to draw attention.  Hi-glow LED’s providing enough flashing light to attract your attention. Can be used as warning light. Specifications Supply...

kicad StepUp allows exporting kicad 3D board and comps in STEP AP214 .By easyw @ sourceforge.net: kicad StepUp: a new approach to export kicad board and modules in STEP AP214 (with colors). With kicad StepUp, it is possible to work in kicad EDA with the same component model data...

Ytai Ben-Tsvi @ ytai-mer.blogspot.com build a PIC based 3W LED Driver that is chainable. He writes: LED Pixel: The Pixie is a color LED module, allowing an external controller to change its color and brightness dynamically. Chainable: The module is designed so that you can chain...

Versatile project has been designed to use in automotive application and industrial servo control application. This project provides all active necessary functions for closed loop servo system using Brushed DC Motor and potentiometer mounted on output shaft of DC Motor Gear. This...

The DRV8871 is a brushed-DC motor driver for printers, appliances, industrial equipment, and other small machines. Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6-A peak current. The inputs...

Clemens Valens @ elektormagazine.com discuss about the new iCoupler family of isolators from Analog Devices: Digital isolators based on transformers and capacitors use magnetic and electric fields to couple data across isolation barriers where optocouplers use light. Digital...

This is a simple 555 timer IC circuit that is able to power two strings of LEDs alternative. Disco lights are mostly used in decoration made with colourful LEDs. For begginners, this is a compact circuit using a single chip IC. IC555 is connected here to form a multivibrator. The...

Tomasz Ostrowski has tested some cheap USB sound cards as low speed oscilloscope interfaces/recorders. He writes: I've tested some cheap ($1) USB sound cards for DC sampling capability, in particular for using as low speed oscilloscope/signal recorder. Some...
