Simple Remote Control Tester

When your remote control TV problems , because not works well , you can use this circuit to check .

This circuit using BP103 which is photo transistor who will response to infra red spectrum when remote control TV problem.
Transistor BC548 will biases and turn LED D1 will flash when you test your remote by pressing the button and make sure the infra red of remote works well. Check it Out!

We have Generic Universal Tv Ir Remote Control Decoder Tester Infrared Remote Control Testing. with this tool you can answer the questions :

(1)How to confirm different TV remote controls can be compatible with each other?

(2)My TV remote control doesn't work, if you don't have the one I need,which model can take place of it?

Use this to test functionality of the remotes before listing them. Super easy to use and does exactly what it is supposed to..

Free Electricity Using Magnet and AC Motor

Magnet Neodymium circle , Big Magnet (blue) replace on between small magnet ( orange circle magnet). Small magnet replace with strong glue on Axis of AC Motor , uses 3 small magnet. And Big magnet glue on static body of AC Motor . Ignition Piezo connected to pole of motor . And after everything is done connected , tested by push the Piezo Ignition on , just once , and the AC Motor will running , and magnet will generate current and supply to bulb, and the bulb light on .
