Air Ionizer

  

An air ionizer is a device that uses high voltage to ionize (electrically charge) air molecules . Ionizers are distinct from ozone generators, although both devices operate in a similar way. These can be turned into devices for water purification, bacterial foaming etc. The circuit  uses a ignition coil from scooters.

Micro Inverter

 

 A simple low-power inverter circuit is described here, which converts 12V DC into 230V AC. It can be used to power very light loads like night lamps and cordless telephones,but can be modified into a powerful inverter by adding more MOSFETs.

Remote control using IR

Image result for Remote Control using ir

Make any battery-operated toy car remote-controlled using this circuit. The circuit, consisting of an infrared transmitter-receiver pair, uses IR beam transmission to switch the toy car ‘on’ or ‘off ‘. To operate the toy car, you need to hold the transmitter in your hand, keeping it pointed at the toy car which has the receiver fitted inside, and simply press a switch provided on the transmitter.
