Led Light Using Cell Phone Battery Charger

a salvaged 5mm led along with a 68OHMS resistor when connected to a charger having 5 VOLTS output produces what is shown below....i topped it with a pyramid made of crystal from one feng shui shop. a very decent night light,,,you could cut a hollow cylindrical translucent portion of any coloured BALL pen to give it the pinkish(mine) look or any other colour ,,,,the charger provides only what CURRENT is needed and i even use it to run a small pc cooling fan. the led along with the resistor is the same arrangement from one of my previous instructables https://www.instructables.com/id/TORCH-OR-NIGHTLIGHT-FROM-A-RECHARGEABLE-BATTERY-FR/.........set the led under the hollow of the pyramid to get your night light....yaaaaaaaaaaayyyyyyyyyy.....the charger was from an old mobile phone rated at 5VOLTS 500mA,,,,i.e, it could provide a max of 500mAmps. the red and black wires indicate -ve and +ve respectively
