Do you want to recharge your non-rechargeable batteries?
Most of us think that non-rechargeable batteries are only for once use. But it also can be use multiple times (2-10 times depending on quality and type of battery) after recharging them.
Here is a simple circuit which you can build and recharge your non rechargeable batteries.
Remote control is a great marvel of modern world. Controlling some thing remotely sounds great. But remote control systems have many limitations one of the limitation is the distance range of the remote control usually most of the remote control systems used in home have range of only 10 – 1000 meter.
Here is a trick to increase your remote control range to 1000s of kilometers by using your mobile phone.
Mostly Clap switch are very complex most clap switch use atleast one IC or atleast 7-8 transistors. So making clap switch for an unexperienced electronics hobbyist is allmost imposibble. But I am here to help you with the solution. The circuit given here contains just 3 transistors.
Most probabley this is the simplest(using very less components) clap switch in world.
