GRYNX » TicTac flashlight

GRYNX » TicTac flashlight: "A disposable torch with long life (I hope I don’t invent the wheel once more) I bought ‘tic-tac’ mint candy and found out that this package must be ideal for 3 AAA batteries to make a small torch (or lamp) with.
Yes the batteries fitted perfect - I soldered them in series and used a small micro switch from an old circuit-board together with an ultra bright white LED (25.000 mcd - 3,8 volt and 20 mA - 35 degrees) and a serial resistor of 27 ohm (to make it 3,8 Volt)."
