At 5v, your probably pushing over 2A http://laserpointerforums.com/f65/3x-445nm-ld-piv-plot-53927.html (look at the red voltage line in the graph)

Be careful with that regulator! A L78S05CV is a higher amp version of a 7805 (5V fixed) voltage regulator... It has a > 1V dropout voltage, which is probably the only reason your diode is still alive. Get yourself a LM317 and a pot for a proper current regulator at about the same cost.

I'm still waiting for my real o-like goggles to get here, but in the mean time I've discovered that a standard brown bud light beer bottle passes only a very dim, diffuse spot when hit with 1W of 445. Heres the spot at approx 1ft from the bottle, with the laser passing through sideways so it...

Well, it died because I kept trying to up the power until I killed it.. if i left it alone it would have worked

No problems on my first red (which died a few months later) a couple years ago or this first 445. See my post a little below this for the cheapest part list I could come up with.

Yeah, I don't have goggles yet, so testing has been pretty much limited to outdoor shots, but I did pop a couple balloons while viewing through a camera... It takes a couple seconds though. The new driver got here today, and I swapped it in and rewired the 3AAA holder to provide 1.5V in...

Ok. I'll agree with you that using lasers would be a bad idea as it would be bad for the hobby. But I still very much support destroying the cameras using other means. Noone is going to put more regulations on guns just because someone decided to shoot a couple cameras... (as opposed to another...

Heres the distributor listing for it, its very easy to wire up the circuit with a couple resistors, post back if you need a diagram. LM1117 - 800mA Low-Dropout Linear Regulator I'd suggest digikey in the US, but I'm not sure if they ship to Australia. You can try ordering a free sample from...

Currently just using the 3AAA holder. I have a 22600 in the mail, plan is to use that with the NJG-18 driver.

Host: $10.00 Diode: $45.00 Lens: $12.50 Driver: $2 $69.50 as of right now. I already had an old aixiz module. I'm going to replace the current driver with a NJG-18 ($5) tho. -------------------------------------------------------- EDIT- Final Updated list: Hotlight Host: $10.00 Diode: $45.00...

Here it is, using a hotlight host and this driver $1.99 - 18V 5W Cree Circuit Board for Flashlights (16.8mm*5.5mm) - Flashlight Parts and Tools set at stock current, waiting for my NJG-18 to get here... Output power unknown.

Maybe if this balloon was coming after you...

I remember being here back in like ~07, learned how to build my first red when the diodes cost more like $50 than $5. Burned the thing out in like a month and kinda lost interest, was too expensive for a high school budget... Can't remember what my old username was, but I think I only had like 1...

The red light cameras here use a lidar gun to detect cars, it sets off my lidar jammer every time I go through.. Might be a good idea to aim that 1W into the detector, I'm sure something meant to detect reflected pulses off of cars won't like a direct hit :D Do it at night with noone else...

Re: 445 1-2W Blue Diodes *Tested* $46 Shipped US $42 Each When You Buy 3 Or More I found an old aixiz from a red that I burnt out a long time ago. How much for a diode and a lens?

Definitely not, I can fit a couple big lithiums in that host with minimal mods.

Heres the host I plan on putting it in, 6-3/4" 109 LED Flashlight Plenty of room for a big heatsink. Its built pretty solidly, I've used it in some other projects (non-laser). I don't plan on running it at full current, maybe pulsed at >100 Hz with a low duty cycle.

The red LED from the projectors... Theres gotta be a bunch floating around out there. Looks like something fun to play with/put in a flashlight. How much do they go for?

Guess I'll wait till I finish the 445 pointer before I start messing with it then.. Hopefully ~1.5W CW will be enough to remove paint from copper. If not, I'll probably look into a PBS cube to make 3W. I'd prefer not to have to deal with IR and the difficulties aligning and focusing an invisible...

Has anyone done experiments to determine the max pulsed power for a 445nm diode? Since they can do 1.5W CW, would the diode potentially do say 5W+ for 10ms with a 10% duty cycle? I have a partially completed CNC XY table that was meant to be a CNC mill, but that got a bit too complicated...
