Here is diagram of the wiring of a Piso Net, which is popular here in the Philippines by using a PC with a Timer and Coin Slot to operate an Internet Cafe even without supervision because it is made to operate automatically. The main issue here is what signal or power source that you will cut to switch it using a relay. Some users are freezing the keyboard and mouse while other cut the signal or power line of the...

This is a project for those who want to build their very own Automatic Battery Charger. This is a project made by one of the member of Elab Forum, duc_tech. But as a reminder, this circuit don't have a current limiter which means this charger is good to use only on a known good battery but not on a battery that have defects like having a short or open plates which will cause the diodes, switching Thyristor and transformer to heat easily....

This is an example how an LCD Start Up Circuit looks like. It shows the flow of the supply which switched on the circuit. This is only a very simple example and other start up circuit may looks more complicated than this one. We can make this image as a guide to give us an idea on how do a start up circuit of an LCD may looks like and how does it function. In this way, we now have the idea of the switching circuit of most LCD Monitor and all we... [ Continue reading... ]
Upon surfing the net, I have found this site: http://electroschematics.com displaying their projects on making a Transformerless Power Supply with a 12 volts output voltage and a current of 100mA. We usually see this kind of power supply on a China made model of rechargeable products like flashlights and mosquito killer. This circuit catches my attention because of its application in our work which needs a power supply and we can also use... [ Continue reading... ]
