Hi guys, I'm happy to post some photos of my completed kenbarrel kryton tube build. This is with a long die open can diode and custom switchmode PSU, glass lens. Total cost: over $100 counting broken diodes leading up to it, etching materials, and parts!

My camera just doesn't do the beam justice! In real life it looks much brighter for some reason.

The PSU is a custom switchmode PSU designed to completely drain the batteries before output power decreases at all. Once the batteries are totally drained, the laser turns off. Versions of it may be available in the future as 'lavadrive2'
 
Absolutely outstanding work!

The is the reason I check this forum is to find the awsome stuff like this!

Great Job!
