Count me in!

Negative towards the spring.....usually.

Was looking at stuff on the Deal Extreme website and came across this notice. Be sure to order soon or be prepared to wait even longer if you are ordering anything from any company in China.

Re: New #120 and #150 Green Lasers from IQS! I just hope Eekbay doesn't get wise to him and yank all his auctions.

Wearing good eye protection, focus the dot to the smallest point possible on a white sheet of paper about 6 inches from the lens. That's the distance you should hold your target.

All winners, tough choices!

I've been doing a lot of experimenting with ambient lighting temperature settings so far to no avail. Shorter exposures tend to lessen the violet effect but they still persist. Next I'm going to try custom white balance settings. At least I don't have to wait for printing them all to see how...

Re: 1-1.2 watt 445nm lasers **ON SALE NOW** CHEAP $165 Yob's is going to be 25-50% more powerful!

Today a friend brought over an Opto 75mW pen and some AAA NiMH rechargeables (forget what brand) to see what the output power was with them. It was very erratic and had trouble even lasing. The fresh charge voltage was 1.3V. I'd say stick with Everready or Duracell Alkalines.

Re: 1-1.2 watt 445nm lasers W/COPPER HEATSINKS CHEAP $180 Don't let a missing battery stop you! Go to Walgreens and get a pair of 123 primaries and fire that bad puppy up! It will work fine with them.

Actually, the street lights are sodium vapor. The camera is new and I have not changed the default settings. I was hoping I was on the right track since it is set for auto white balance. I'll play with the settings to see what works. You guys are the best. So much help and knowledge here! :thanks:

I have a Canon T2i (EOS 550D) and the beam shots of my 445nm look very violet. Does anyone know how to adjust the color rendition to more accurately reflect what the eye sees? Is that white balance or some other setting? This is my first digital SLR and the number of settings and flexibility is...

Re: 1-1.2 Watt 445nm Host Ass'ys w/Driver and Heat Sink ONLY $50!! I just wanted to share a photo of my finished Survival Lasers kit with a DTR A140 diode on the LPM. Needless to say, I'm very happy!

Cool! Awaiting your review with bated breath.

Anybody bought a Super Power #100 Green Laser Pointer Visible Beam W/Box from our guy itemquickship yet? I'll bet it's a nice AAA pointer!

Haha, I hadn't noticed the sticker over the other one. Good catch extremeodd. Just a little nitpick here, but the lanyard will barely fit over a small child's hand. Not useful for much unless you're going to hang it up to store it.
