Thought I would just update this post since it has become a complete laser. Some nice video of the beam etc. --- Nothing beats a nice Ehgemus host! Was getting kind of tried of all the cheap dx hosts I had. So I contacted Harold and told him exactly what I wanted. This host has a massive 32650...

I just put together a rather nice laser. A quick test on my LMP shows 2.3W. Did the normal quick check of the laser without the lens (G2)on a wall to see if all is good. That is when I noticed these dark spots. Since I took off the lens I take it there is something on the M140 diode window? I...

Chargers are just one of those things people don't think about until their house burns down. I needed a charger for my 32650 (D size) Li-Ion batteries. My Pila charger was nice for my little "wuss" Li-Ions with its 600mA. Right so a 32650 (6000 mAh) would need 10 hours to fully fill with the...

I got this crazy idea wanting to make a knife edge using 4 (later 8) M140s. No PBS (for now) just 4 mirrors reflecting beams 90 degrees to making a nice row stacked for the anamorphic prisms to clean the beam up. Not super advanced it would seem. If this works out nicely Ill mount it to a...

Are there monochromatic yellow lasers between 570-580nm? Around 100mW would be nice. I would think there would be something that you could pump a non liner crystal with (DPSS) that would give something close to the “magic green” 555nm. The frequency the eye is most sensitive to. Prolly just...

I have been using AW IMR red unprotected cells for most of my builds. I am always worried about them being discharged below their braking point. A real pain to check the voltage all the time. Recently I needed a D (32650) Li-ion. Picked up a Feilong over at feilong (the postage was stupid...

Normally I don't rant about things like hosts. Ehgemus host deserves an exception! Was getting kind of tried of all the cheap dx hosts I had. So I contacted Harold and told him exactly what I wanted. A proper plagiarized RPL like he made for Jordan :) This host has a massive 32650 “FeiLong”...

Wow … I just got hit in the left eye with 2352mW of 445nm laser light from about a half meter away. The reason I am here writing this and not getting eye surgery is because I had a good pair of goggles on. I am still really freaked out. If I did not have those goggles on I would be blind ... its...
