Speed Controller for Small Cooling Fans - Give a try

Small cooling fans are used in some equipment for cooling semiconductor devices. The circuit given here is of a simple automatic speed controller for a 12V, 0.6W (or 1.2W) cooling fan that increases the fan’s speed when temperature rises, and vice versa.

Recover Deleted Files in Linux

Have you accidentally deleted an important file because you have the habit of usingShift+Del instead of only Del? Well, don’t panic. I had this very problem some time ago, and found some utilities that helped me recover the so-called “permanently deleted” files; so thought of sharing this useful discovery.

Linux on The POWER

I guess that almost all desktop systems in the office or home are derived from one prototype, the IBM PC (personal computer), which was built around the concept of an open architecture that IBM introduced 30 years ago.

How to create a Printed circuit board

You did some computer aided simulations and the circuit is working great. Only one thing left! You need to create a printed circuit board for the circuit so you can see it in action!

Automatic Evening Lamp

Presented here is a solution for switching off outdoor lamps even when you are not at home. The lamp turns on in the evening and turns off in the morning so that there is no need for manually switching it on/off. The circuit is directly powered from AC mains and can be enclosed in a plug-in type adaptor box. It can drive a bulb, CFL, tubelight, LED lamp, etc up to 200W. Author’s prototype is shown in Fig. 1.

Battery-Discharge Measurement Circuit

Battery-life measurement for a portable system is a time-consuming task and many methods used for it do not give reliable results. Presented here is a circuit using which you can measure the battery-life very easily. Here, an analogue clock tracks the discharge time of the battery used in battery-powered portable 
devices.
