LED Flashlight

This flashlight I have been using about 3 months ago, I was quite happy with the result although a little difficult to install components. The idea comes from here: http://www.instructables.com/id/LED-Torch-2, there are some components that I replace it with what I have.

Electronic components that I use is:

1. 8 mm straw hat LED
2. 6.8Ohm Resistor 5%
3. Diode IN 4007
4. Push Button Switch(http://www.ebay.com/itm/10x-Red-Push-Button-Switch-6-Pins-Latching-DPDT-Tact-Tactile-Self
