How to Build a Red LED Torch
Submitted: Tuesday, 21st February 2006 by Chris Marsh
If you are anything like me you probably have a handful of torches lying around that you don’t use anymore. I was going to buy a Red LED Torch, but I thought I would try and convert one of my existing torches first. I managed to convert a flashlight that has been lying around for years.
This is a very simple project and only takes about 10 – 20 minutes if you have all the parts and know a little about soldering.
What You Will Need
I use NIMH rechargeable batteries because they are a lower voltage ie 1.2V instead of 1.6V. I do not recommend the use of alkaline batteries as you run the risk of popping the LED.
