Silicon Chip February 2012

In stock now the February Issue of Silicon Chip Electronics Magazine, with a wealth of interesting articles and projects, this magazine is ideal for the electronics enthusiast. This month's articles, include an interesting article about converting a washing machine smartdrive for use as a Motor. The washing machine motor with smartdrive can be obtained very cheaply and includes a smartdrive that can be used to control the speed of the motor. This variable speed motor can now be used in a wide range of power applications. Also this month a look into DCC, the digital control system for model railways, in this article, we cover the technical basics and some background on the system.

This month's projects include an easy to build 10W LED Floodlight. Ideal for lighting the backyard or pool, this unit is based on long life LED's and can easily replace the halogen lamps used today in floodlights. Also this month, a professional semiconductor test rig, this unit is able to test, LED's, Diodes, Transistors, MOSFET's, SCR's and also TRIAC's. Featuring an LCD display with professional case and easy to follow instructions, the unit can quickly test the performance of your semiconductor parts. Finally this month, a simply 1.5A Switching Regulator, this unit will deliver quite a large current in a very compacy size over a range of voltages from 1.2V to 20V. All projects come complete with circuit diagram and electronic parts list.
