Years ago I posted my thought on The BEST LED Flashlights.   Unfortunately a few things have happened since publishing that post: 

The Nifty-Stuff LED Boost Circuit / Joule Thief is a device designed for two purposes: 1) To suck any and all traces of juice from your “dead” batteries. 

I’ve had a lot of fun making up many different versions / modifications of these tap lights (also called touch lights, push lights, closet lights). Over the months I’ve received requests to make custom modified LED tap lights. I noticed that on the net there aren’t many options available for LED Tap Lights or an Read More …

Led’s are a great solution when replacing incandescent bulbs in many applications. One problem is that LED’s don’t like changes in voltage & current. For example, the voltage from a car battery can fluctuate quite a bit from 11 – 14 volts and this can be a big problem for an LED.  If you design Read More …

This was actually one of the first LED conversions that I did, but I never posted it because I’ve been wanting to re-do it to make it nice and pretty.  The problem is that it works so well that I haven’t been pressed to make any changes.  This being the case I’m posting the modification Read More …

In addition to the LED tap lights I’ve made, I’ve also received requests for some custom LED lighting applications. I usually use bright white LEDs or the bright blue LEDs for these projects but have many other colors to choose from. For most of these applications a very special circuit was designed to run the Read More …

Misc. wires, solder, etc. Here is the flashlight prior to Read More …

In July 2003 I bought about 120 LEDs and have since been converting everything I can get my hands on. I’m not an electronics buff, but I love to tinker. Below are the very first mods I made: The LEDs that I work with are the standard bright white or blue LEDs, the specs are: Read More …
