Intro: How to Make a Powerful Flashlight With Just $2
Introduction: why do we need a flashlight? Well we need it everywhere, including dark streets, walking in the nights, searching for a lost ring or coin, looking through a dark window, searching for a big cockroach who has intimidated your children or even committing burglary! It was a joke… I thought buying a powerful flashlight is expensive and if it is Chinese made it would be prone to failure, so why not making a cheap and funny one, so I have started to do it and it is incredibly easy as follows:
1- An empty box of cream
2- A cylinder container of Vitamin C
3- A COB 5 W LED white color
4- A small switch
5- Two 9 V batteries
6- 2 pcs 9v Volt Clip on Type Battery Snap Connector Lead Wire Plastic Head
7- Two screws
8- A circle made of metal sheet with 0.6 mm thickness, the diameter of that should be equal to the internal diameter of cream container.
9- 10 cm of electrical duct
10- Good Glue
11- 10 cm wire
1- Soldering Iron
2- A drill
3- A cutter
1- Make a hole equal to the external diameter of Vitamin C container on the cream box and then insert the cylinder inside the hole and glue it.
2- Split the duct in two halves and glue it to the back of cream box.
3- Make the connection for a circuit in which two 9 V batteries are in series connection to make 18 V potential difference to activate the COB 5W LED
4- Make for holes on the metal circle two to hold the LED with two screws and two to insert the connecting wires.
5- Make a small rectangle on the Vitamin C container to install the switch, but the switch should already soldered to wires.
6- Put the batteries inside battery holders and screw the LED to the metal circle base circle and solder the wires to it
