Well it says for lasers and related things so I decided against it. Oh, and they are much better quality than buckyballs. I have owned both.

Not sure if this is the appropriate place to do this but I have 3 extra sets of Zen magnets that I am looking to sell. If you don't know what these are just watch this YouTube - Never Let Go of Childhood Wonder. These are the "Retail Sets" which come with a wooden box, velvet carry pouch, a...

This may be a stupid question but I see that almost all green lasers start with an 808nm pump diode and then passes the light through a Nd:YVO4 crystal to convert it to 1064nm and then passes through a frequency doubler to reach 532nm. And all of this done up to a maximum of around 30%...

Re: Nova laser 125 PM sent. :)

Im all for laser safety, believe me. But one thing that really bugs me about this forum regarding safety is :horse: I think he gets the picture, pretty soon its only annoying to hear the same thing from a dozen people. You've proved your point, If he cares about his eyes and the longevity of...

Awesome! I love how you use lipo instead of li-ion. I always scratch my head as to why they don't make them into standard sizes with protective PCB circuits. Maybe even then its too volatile?

All of the parts were run on a CNC Mill including the engraving.

Re: Custom 445 Polished Brass Schweet!!! Haha I almost bought some copper stock cause copper gets unbelievably shiny but like you said, tarnishes very fast. Brass should last a little longer and I can easily whip out the dremel and buff it again if I need to. But daily use should keep it up to...

Alright so I have been away for quite a while and decided to check back recently and found out about these super powerful blue diodes. And since I have always wanted a blue laser, I couldn't resist doing another build. However, I wanted something unique and different that was also portable. I...

Hmm thats strange, I just ran mine up and the resistors don't get warm at all however, the two black chips on the one side, as well as the big circle piece (lol @ me for not knowing the official names) get warm to the touch. They feel hot if you touch your mouth to it (yes I know thats weird)...

Re: H1600 - Possible higher-powered 445s? Not just a new "model number" this time ;) I don't think it will have a green diode based on reviewing the little diagram in this: http://www.greenslimprojector.com/resource/pdf/pro_series_npi_3_28_11.pdf "...by efficiently converting blue laser light...

Sorry for the bump on the thread but did you ever get your results dvant? I also received one of these drivers (the aixiz version) and when I hook up a freshly charged 14500 battery, I am only pulling 1.3A however the current climbs gradually. When I tried with a cr123, the current was right...

Yeah thats what Im wondering, I have seen switches that have different current ratings at differing voltages, maybe I should just go for it, I have a feeling it should work.

Hey guys, been out of the loop for a while and am building a custom laser and am in need of a clicky switch that is <16mm in diameter that is capable of handling a 1.5A current. Please do not suggest this: $1.94 - Clicky Switch for Flashlights (16mm 5-Pack) - Flashlight Parts and Tools This...
