Yeh a E-Cig place sells AW batteries over here for $10 each. It's nice to see a E-Cig place actually selling good batteries instead of ultrafire crap.

I sent the request in with the link to the video. I hope they don't want me to send the bad battery back though. I live in Canada and it would cost me more in shipping then it would cost to buy one at a store here. If i REALLY need to i have parts to build a voltmeter, but that would take waaaay...

The batteries I ended up ordering were 4 18350 KeepPower 900mAh ICR18350 Protected Button Top . The problem is one of them seems to be defective. The laser I said I ordered in the first post takes 2 3.7V batteries but when I use the one I think is defective it turns on only for a split second...

I'm looking to make or buy some sort of large UV reactive surface to write/draw on with a laser. I'm not sure exactly what to search for when looking for something already made, but ideally it would be just a large thin square plastic sheet. If i can't find one making one would also be a...

Re: Question about these safety goggles. What? in that topic "Pi R Squared" linked someone tested the exact same glasses I bought with a blue laser even more powerful than the one I'm getting and nothing made it through. https://www.youtube.com/watch?v=lsE9nkMUxuQ

Thanks again. I'll get that i4 since it charges AAA batteries too and i have a few things that burn through 4 AAA at a time really fast.

I'll be receiving the 2W-2.4W version of this laser soon SF501B 445nm Blue It needs 2 16340 batteries and all I have are some ultrafires I have around that I bought off ebay or amazon at some point in time and I keep reading that they are terrible, don't put out the advertised mAh and such. I...

Re: Question about these safety goggles. Ah, thank you! I'm glad my shot in the dark bargain basket glasses are good. I was worried when it didn't say what nm they were rated for other than "blue and green". The hard case is a nice bonus too.

Re: Question about these safety goggles. I should of re sized that. They also have this on the frame

I ordered these off amazon for a 2W-2.4W 445nm laser I ordered http://www.amazon.ca/HDE-Protection-Safety-Glasses-Goggles/dp/B009T6RN0G I received the glasses before my laser so I looked up a visible spectrum image and the whole area around the 445nm point was black when I looked at it with the...
