LIFEHACK AUTOMATIC LIGHT IN THE ROOM
So often we are faced with the fact that entering the dark room of the apartment (the garage, barn, cellar, cottages etc.) for a long time we are looking for a light switch, we make our way to touch it, we are afraid to stumble and drop something. Therefore, I offer you the simplest, cheapest and autonomous device. Auto light switch! Turning on from opening the door. Trailer its operation is very simple: the door opens - the light turns on, the door closes - the light turns off. Also, the lamp can be turned off so that it does not turn on constantly when the door opens. The lamp is powered by batteries, which is very useful in the absence of electricity.So we need:
- headlamp
- the most common wire
- switch
- roller for of furniture
How to do it, you can see on this video:
