Wireless Remote Light Switch Circuit

When looking for a remote light switch, I found a fairly simple circuit and very universal in use. This circuit can be used to control any electrical line powered devices such as a television, fan, lamp and others using the IR remote control.

However, the more I focus on this circuit for use as a remote light switch. Remote usage of some functions is the more indoor switch, if not complete when the remote control must be aimed at an outdoor light. For the purposes of outdoor use, I think should be the circuit control switches should be stored in a safe box from the water or wet, and then usually for outdoor use. The infrared range should be increased.

The advantages of the remote light switch are that you can re-use a remote control that has been unused in storage. Almost everyone today has a pile of old IR remote is left of their equipment have long ago disposed of them. With this circuit, you can put them back into use.

17V Switch Mode Power Supply Circuit Design

Here is a switch mode power supply design which is a stabilised DC power supply in a compact, specially designed to get the best performance of the Active Loudspeaker System. Switch mode power supply is capable of sourcing up to 10A and has an excellent efficiency and produces the ideal supply voltage of exactly 17V.

Switch mode power supply is designed using two ICs LT1074 regulator. LT1074 is an integrated step-down switching regulator that can source healthy 5 A and further requires very few external components. IC1 to function as a ‘master regulator’, while only IC2 springs into action when riding on top of 5A output current.

Battery Load Tester Circuit Project

Almost every vehicle either in the air, on land and at sea have a battery. Start light to heavy duty equipment, therefore, you need a battery load tester available at any time. Having a system that is reliable and has proven to give accurate readings. With a final conclusion on the decision to use batteries that you have today, or you should replace with a new one.

Commercial battery load tester are priced from reasonable to more expensive, and the unit price and a higher offer is very good not only viral, but the stress test and alternator and starter testing as well. Many of these are built with the rugged “carbon” pile resistors (some variable) and some with microprocessor control and metering luxury.

So that you can know about a battery tester, here is a homemade battery load tester project, built with budget in mind. It consists of several “nichrome” wire loads applied to the battery through the starter contactor old, and LED bargraph voltmeter thrown for good measure. He also has a fan too.
