Hi LaserCo, if the cunning stunt works, it will truly be a stunning **** :D My brother is into astronomy big time and makes his own lenses and mirrors, so the correction optics are going to be 'home brew'. I've done a very quic experiment and the theory sort of stacks up. Never done anything...

Hi Arg Not yet, but I did play with the red and green to get a feel for the adjustment. Need to get some decent dichroics before setting up properly. ATB MM

Short, out of focus (sorry) video of the laser cycling RGB. ATB MM

Hi, Could you post a photo of the PSU, driver and diode all set up? ATB MM

638nm is the way to go and I have a "cunning plan" to get the Mits 300mw divergence under control..... Some stuff arrived today for a little experimentation over the weekend. ATB MM

Hi Flare, sounds interesting, please start a build thread and share some photos.:beer: Hi Hobbes, I might make some, but got to get the first one working first;) New photos...1st post. ATB MM

Hi Ed, Well it's my dream...... I just wish I had simpler dreams :D I do the design in 2D and then use this as the base for the model in a CAM program, this generates the GCODE for the machine. I programmed and made the parts, it's my day job button pressing on a machining centre. The turning I...

Ok, this may be a simpler solution to scare the locals without the need for lasers / helicopters etc. Pop this on and walk down the street :) [Alien Mask UFO Space Creature

Surely, with lasers being so common place now, people who see the "UFO" are going to say, "wow that's a big laser"..... rather than "run & hide, save yourselves, aliens are beaming up people with a tractor beam to do terrible experiments on":crackup: I did see a laser show writing messages on...

Hi Things, The blue didn't look that fat in reality, but the red, sheesh!!!! has to be 10x wide as the green at about 5m....so some work to do. I think I'll end up having to defocus the green a bit it to match the divergence of the blue and correct the red as best I an to match (I'v some ideas...

New photo showing the modules and drivers powered up - 1st post. ATB MM

Hi, Have a look at Synrad - CO2 lasers. (expensive $$$) The depth will be the main problem for a laser, but might give you some ideas. Dremmel or a high speed spindle sounds like the best method.

JK, don't say "I want a burning laser" Say , "I would like to build a 638nm red laser for optical experimentation" Google some cool experiments you can do (eg, simple interferomenter), much more interesting than burning stuff - well almost ;-) ( Keiichi tsuchiya, whats with the huge photo of a...

Hi, New photos added to post #1 of the "drivermountheatsinkthingimabobie":) ATB MM

Looks like ImageShack has a problem, even their home page has the blank windows with the red crosses. Hopefully they will sort out the problem and restore the links. Last photo was just of the 3d model of the driver mount, should get it turned to metal next week. ATB MM (Photos back ... phew!)

Hi, For another £6 you coud get an extra 100mw and put it in a host of your choice? 150mW Powerchecked Green Modules (Spring Contacts) - Detailed item view - OdicForce Lasers Online Shop ATB MM

I've been a bit lazy the last few days:yabbem:, but managed to get the driver mount / heat sink thingie mabobie designed. Photo of it in the 1st post. ATB MM

You made a 'FLED' (filtered light emitting device) not a LASER (light amplification by stimulated emmission of radiation) ;)

Hi Things, Yup, I seen the other hand helds and was aware that this wasnt't the first - not many things in this world now that hasn't been done already. However, once its all assembled and working, there is at least 1 more suprise about this RGB hand-held to come ;) :shhh: :) ATB MM

He might have a camera attached rather than looking "down the spout"?
