Yeah I've got a 5mW red to play with the cat. With the BR I made sure that the beam was pointed so he couldn't look into it (it was sitting in a vice) - I wouldn't feel too smart if I blinded my cat. Still, I might keep the cat away from now on, seems like a good precaution.

I noticed some people said they were having trouble focusing them. Seemed fine to me - although I'm not going for a burner, just a collimated beam. Just used three different distances and a vice to hold it steady and it was fine. Har har, my cat's sitting looking at the dot mystified and...

Yeah.. so.. I read through this forum a bit and see that 405nm light is quite difficult to focus on. Interesting phenomenomonom though!

Thanks to a recent GB by BluRay (good job!) I got myself an 803T and got it working. It's all attached to a bench supply at the minute, and sitting in a meredith glass module, but still very cool - first time I've had anything but a red laser. I'm running it at 5.2V @ 109mA. One thing though...

Cheers for the reply, I think I'll go ahead and put the 803 into the module. Maybe get some thermal paste and stick the 22x red into the other one, hopefully that'll stop it from burning out!

Hi, sorry if this has been covered before but how good are the heatsink properties of the aluminium meredith enclosure? In your collective opinions would I need more heatsinking than that for a red 22x open can and a PHR-803T? I've got two and those are the lasers I am intending to put in them...

Re: Laser Engraver on the cheap Yeah I've been doing some further research - got as far as finding a bit out about a few specific plotters and it seems a nightmare to get the things running. That said I found this - engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/ and the...

I'm playing around with the idea of building a laser engraver from an old flatbed pen plotter and er, a laser. I was thinking of biffing a ~300mW 22x red LD into it originally, but on further research I think that might only be capable of engraving fluff and if I'm lucky, foam. So maybe I'll go...

Re: **20X Red LONG OPEN CAN SLED GB $14.50 Shipped Cheers BluRay, lookng forward to getting my lasers up and running. Feel like I've been building this thing for months - I'll have to try and make these two last longer than ten minutes!

Re: BR PHR-803T Sleds or DIODE $13.50 Shipped Anyw @ BluRay Thanks for letting me in on the buy, I was feeling a bit hard done by having to gut another £22 DVD-RW, and was considering just leaving it and keeping my 'two matches popped' memories! I'm especially pleased about the PHR-803T -...

Re: BR PHR-803T Sleds or DIODE $13.50 Shipped Anyw I'm using a modded ATX for a bench supply and I had a LM317 driving it at ~380mA so I'm not sure what happened. Was an odd one because I'd set 'er up and focused the beam, then went to watch some TV. Came back and plugged it in and nothing. The...

Re: **20X Red LONG OPEN CAN SLED GB $14.50 Shipped Hi BluRay could I get in on this buy for one bare diode as well please? I've PMed you.. and posted in the other thread. I'm only planning on having two lasers. Until the next one. Dammit I know how this is going to go!

Re: BR PHR-803T Sleds or DIODE $13.50 Shipped Anyw Hi, I just registered here today. Sorry for my first post to be in the gimme-gimme section. Been reading on the forums for a while and it's a gold mine of information on lasers. I'll try and contribute some stuff if I can, although so far it...
