Intro: Let the Sunshine In
Simple idea to use the windows as lightning equipments. (Solar Charged)
Step 1: The Mirrors
Fixing two mirrors on the size of the window, looking in each other.
Step 2: The Circuit
Build a simple circuit which will make charging and controlling available. A regulator for charge. A photoresistor with BC547 to switch on the circuit in the night time. A PIR motion detector for turning on the lights with any motion in the room. A timer circuit with 555 to turn it off in 1,5 minutes.
Special thank to ELECTRONICS HUB for the timer circuit design.
Step 3: Assembling
Connect 10 x 1.5V Solar cells in serial (+ to -), stick them with silicon on the mirror. Put the rechargeable batteries and the circuit in the cable canal. Fix them all together.
Step 4: On the Window.
Screw the equipment on the window.
Step 5: Circuit
The simple control circuit.
1- LM1117 (is a small one but LM317T or L7812CV is ok too)
2- BC547 x2
3- 10 X 1.5V Solar cell (connected in serial)
4- 10X 1.2V Rechargeable battery
5- Resistor 220KOhm
6- Photoresistor 5mm.
7- Diode 1N4007
8- PIR sensor
9- Resistor 10Kohm
10- Resistor 120Kohm
11- IC 555
12- Capacitor ceramic 0.1nF (104)
13 Capacitor 470μF 16V
14- LED strip
