Hi All, I've recently been a little hard up on funds so have found a little free entertainment. It's baiting the scammers. I've read a few very funny outcomes from others and now am talking to a couple of scammers and giving them the runaround. Has anyone had experience of this pastime? Has...

Hi All, Well, it's been a long time since I posted a build and we can't have that now can we! This was a quality 100mW 532nm Viasho laser at some point but unfortunately it seems all the photons ran out and the output had become... Let's say disappointing to be polite. I was set on the search...

Hi All, I have a couple of questions regards polarization please. I will try to be clear in text as I have limited access to pics but I hope you will all be able to understand my queries and offer some insights... Firstly, the aim here is use PBS cubes to combine two magenta beams. Each...

Hey All, Having turned down my project proposal last year involving lasers, my Engineering Manager now seems to have got interested in lasers. He had now purchased a 75W CO2 cutting system for the college and seems much happier to let me build my initial proposal! The downside? It also seems...

Hey All, I had the opportunity to play with my corrective optics from Dr.Lava last weekend. With all the cool stuff available from him I am a little embarrassed to say these have not knocked my socks off. Following the instructions supplied was not difficult but the results were...

Hi all, Well, Round 1 went well, so, as promised, and now that all the sleds from Round 1 are sent, (the last three to go are at least packed and will go on Monday 4th Oct! ;) ), I can now start taking interest for Round 2 and putting names to sleds. Please see the details in the first post...

Hi All, I've been sent a new source for 12x BR diodes so here are some pics and output info. It looks like it could be a, "New Kid on The Block". [EDIT: I won't edit the title as it may confuse but... It seems this may not be the BDR-S06J sled but the 10x sled from the LG drives posted here -...

Hi Guys, I have another GB for you... This may be a moot point with the arrival and interest for cheap 12x sleds but supply may not be gauranteed long term and it's always good to have a fallback position. So, in the interests of a reserve trench I can offer you... The Sony SLD3236VF diode...

Hi All, Thought you might like to see my latest build. The host for this is not one I've seen used before and was chosen specifically to dissipate as much heat as possible but be small and compact and still run from just 1 x 18650. The photos are limited at the moment and before anyone...

Hey folks, [EDIT:] 2nd Round can be found here - http://laserpointerforums.com/f55/12x-sled-gb-round-2-go-56329.html Thanks. Okay, it looks like it's on for real! These are Lite-On sleds as found in this thread - http://laserpointerforums.com/f38/harvesting-lite-12x-52254.html...

Hi All, I was sent an 8x, (well 320mW pulsed from the spreadsheet which means the same!), diode to test and would appreciate your seasoned eyes being cast over the results. First of all, the threshold seems a little high to me and I've not seen any on graphs reaching Vf of 6.5V! The...

Hi all, I think I'm going to regret this initially but I think the time has come to put some figures on this for my supplier so I can apply some pressure. I've been looking at getting some supplies of 12x sleds but the Chinese seem to be protecting their own by supplying to laser companies...

Hi all, As we know, we are pushing these boost drivers, (I include the Flexdrive here), trying to run 445s at full bore from one 3.7V battery. This creates a lot of heat during the boost and I'm wondering what parts on the Microboost should be particularly cared for? I have a build in progress...

Hi All, For the last few days, when I try to choose the font size 1 in posts, the font actually gets bigger?! Is anyone else suffering from font envy? [EDIT: NVM, sorted] Thanks, M :)

Hi All, This might not be the best link in the world but it might be the best attempt at a link to the world - Big River Man Check this guy out. A man against the biggest river... A man against one of the biggest obstacles a human can undertake... A man against his own demons... A man on...

Hi All, I did some testing and measuring the other day whilst putting together a 445nm build and found what I think are some interesting results. The build uses a Flexdrive and the idea was to simply max it out and see what happened. The host is a 18650 host with a custom heatsink, an A-130...

Hi All, I'm sure I don't really need to post this but Glenn deserves a mention. I've had a couple of transactions recently with Glenn and had great feedback, answers to questions and contact. The first was for a number of 8x sleds for a few of us UK guys. We managed to tie them all up...

Hi All, I'm now doing a limited time special offer on 6x diodes and sleds. The offers are: GGW-H20L Sleds - $38 plus shipping and PP fees, (further dropped to $35 :eek: ! 02.09.10) Note the finned heatsink, bottom left, so these are not the 4x fakes. SF-AW210 extracted diodes - $25...

Hi All, I've been building lasers for a while now but never tried to actually pop a balloon. I thought this was supposed to be pretty easy but when trying to burst my first balloon today I suffered a serious fail! It's fair to say that this was a distance shot so it wasn't as straight...

Hi All, As there has been a rush to get a good solution to the dire output of our new acquaintance in blue I was sent a 3 element AR coated lens similar to the Aixiz one to compare. It is a full threaded body and looks to be identical. Here are the results: Beam with Aixiz lens at 8.8m...
