wow thats funny I noticed the same thing in coke a while back and went on a quest asking professors of different departments what they thought. I found after a bunch of experiments with different drinks that the sugars were pretty much the only commonality. General consensus as I understood it...

Perhaps a stupid question but I bought the reflect red/pass green dichro pack and one of these: Lens-Base-Holder-Mounter-RGB-Optical-Combination-RGB-Laser-Beam-Adjustor Anyway I just received it all and while everything looks good I just realized that I dont know how i'm supposed to attach the...

I received your payment and packaged it all up last night but I didnt get a chance to print out the label or take it to be shipped yet. I get off late this evening but i pinky promise ill send it off before i go to bed and send you the info. :) EDIT: Just posted it and tracking info sent to...

After doing a little research im afraid $10 shipping to the netherlands is just too optimistic. It cost more than that just to ship these to a different state. If you really want these youre going to have to up you budget a bit. Otherwise leave it for someone more enthusiastic about them as...

Yeah ok if you want some I guess i'll see what I can do about the shipping. Also, to everyone reading this. I'm not certain if there are more than 2 so hold your horses until I can confirm supplies tomorrow.

I shouldn't even dignify this with a response but god i laughed so hard when i frantically flip open lpf expecting to read an interesting, topical post and then i am given this...

ok shouldn't be a problem. Don't forget to pm me your address. Do you want it intact/cut down etc

The cost is going to be $10-14 in shipping plus $15 per unit or they may be back up to $20 depending on how many of the original 6 I have left at the lower price. Once they are gone then I may be able to buy more but they may go back to charging $20each since it's not the holiday week anymore...

So after taking another look I agree that this is probably the best way to ship 2-3 intact units for $13.45. unfortunately usps doesn't offer a smaller box with useable dimensions for single units but I could easily fit several cut down units in a fedex one-rate small box and that would only...

Ah good point. Somehow managed to forget about that even as a Brit living in the states. Although working over the break doesnt help! Maybe im a little bit subconsciously salty beause of that lol

Ok I was able to get a bunch of them today so you guys can take them if you want them or if nobody else wants them i might put in the effort and try to part them out. I havent heard back from those I pm'd so if they dont message me in the next 24-48hrs then they are free game. Im honestly quite...

Yeah man its in hillsboro you HAVE to go. Im confident that you will at least salivate + possibly experience bladder failure. Its massive. They have several boxes of working 660nm-ish HeNe tubes, an entire wall of mysterious optics and a bin of suplus 1-50mw 660nm coherent diode modules worth...

Ahhhhhhhhhhh yes much more concise than many posts ive seen on the topic *cringe*. I finally understand!! Thanks! :D

interesting. So if I were to get a driver that was rated for higher it would only provide as much current as the diode pulls?

OK I just went and actually measured it. 2 3/8" x 5 2/8" x 10" and I would say at a guess that it weighs less than 2lbs (amazingly, I do not own scales of any sort!). So i'm afraid it wont fit that box but perhaps there are others which are a bit more square?

oh really? i've never really read up on IR diodes I just assumed they would be around the same as the shorter wavelengths...I suppose it would only take a very small driver then. Are they easy to come by and do you know any to recommend?

pm'd you both. I dont ship things very often so I have no idea how i'm going to do that or how much it might cost. these things about a foot long but are surprisingly light. They do come in that hard plastic shell and a big antistatic bag so i'm not very worried about things getting broken at...

hmm, and you think it scans by reading the reflecton back to the photodiode? I think that makes sense in a way... good idea on the arduino and I actually already have one! Dont you need a lot of power to run steppers though? I would be surprised if the board could drive one although im sure...

Hey guys so in a surplus store I recently discovered I found a whole box of these optical assemblies for crazy cheap. Perhaps somebody could help analyze it and help me decide what to do with it. Given the quality of the diode holders and the optics it might be worth the $15 just to salvage the...

Thanks guys! I cant believe after all this time I never noticed the search bar at the bottom! Normally I have to go through ALLLLLL that extra effort to click "lpf search" at the top so thats a lesson well learned already! :thanks:
