Flashlight for phone

Flashlight for phone

As you know, a phone's flash can be used as a flashlight. But with prolonged use, it can burn out and fail, and it also consumes a large amount of electricity, which causes the phone’s battery to drain quickly.
Advantages of my flashlight option:
  • Compact size.
  • Bright light (slightly inferior to the phone flash).
  • Low electrical consumption.
  • Ease of manufacture.

For production we will need:
1. Light-emitting diode (diameter 5 mm, voltage 3 volts, color white).
2. Resistor 100.Ohm.
3. Micro USB plug with housing.
Tools: soldering iron and wire cutters.

Manufacturing process:


1. Approximately determine the length of the resistor legs and LED.
2. We cheat all contacts.
3. We need to close pins 1 and 2 of the Micro USB with a jumper (as shown in the picture).
4. Solder Light-emitting diode to the resistor (in this case, it does not matter which contact, without observing polarity).
5.Pin 3 is (+), and pin 1 (-) (as shown in the picture), solder the plus LED to the plus of the plug and minus to the minus.
6. All that remains is to install the micro USB into the case and close it.
Thank you for your attention!

    Interesting solution! And by and large there is nothing complicated, Light-emitting diode getting it is not a problem and installing the flashlight on your phone is very easy. When we were on vacation, we did something similar in our tents, only with AA batteries.

    I advise you to take the connector from the broken charger or headphones. Better of course from charging. There is no confusion with the wires - you take black and red.
