Thanks for the replies. I emailed Erv and he got in touch with me. What a great guy he is. It turned out I was using the wrong type of resistors for a 3w led rgb. All sorted now for the moment!
Wow Crafty! That blaster build is awesome. Hopefully I get mine to look half as good as yours. If you don't mind Crafty ; would it be possible to use your expertise along the way of my build. I just know I'm gonna run into a few problems! One that's been racking my brain is how do you mount the luxeon RGB inside the barrel front end and how do you stop the inner barrel with the progression LEDs on from moving about inside the main tube?
Any feedback would be greatly appreciated.
Thanks again guys.
