Looks like it might be misty tonight - hopefully take some outdoor shots. I poked the laser out the back door last night and I could "scan" lines / circle on the low clouds ! Hi Grainde, no not yet :cryyy: but will work on again soon. Hopefully the outdoor shots / video will show the "special...

My favorite is the third photo - looks like they are about to have a game of conkers.

Re: A little build I've started. Ooooowh, Please give some details - looks like an interesting and different project. Can't wait to see what the format will be:beer: ATB MM

Hi, My 2p worth. Using a laser with focusing optics in order to provide a small spot size, you will need to compensate the focus from the centre of the scan field to the outside (as the distance increases / changes) to ensure the spot size remains constant. You can do this by a secondary lens...

POWER UP !!!! Three quick photos of the laser powered up- see first post. ...to say I'm pleased as a pig in $h1t is an understatement....I'm off to have a :beer: More photos and videsos to come. ATB MM

Saw this during my breakfast - I'm going to be smiling all day. Thanks Cyp, made my day already:D

Update 1st post- Photo of batteries and contact spring PCB ...thats a good sign;)

I think the best way to start is from scratch - you will have absolute control and limits the chance of you being ripped off. a) Find a supplier/s of quality lasers that will be legal to sell in your country. Do this by searching the net - start small - if you start placing large orders, think...

Groundhog day again :D

Come on flare, stop teasing us all ..... this was 2nd Dec ;):D

Hi Flare, Very cloak and dagger:D How about a JPG. of the pcb design or photo / pick of the head design / parts? What is the specification, or the aim, progress so far, how you doing it, who's helping etc etc etc. What will your PCB do? does it have the drivers built in? what are the controls...

:shhh::shhh::shhh: She might be listening :tinfoil: .

Hi cairan, Grainde is correct, just the red green and blue laser modules cost nearly $300, then there is the dichroics, mirrors, mirror mounts, PCB's, electronics, lcd, all the machined components etc. etc. I'll have to add up the invoices one day when "the wife" is not looking ;) ATB MM

Buying a website is not the same as buying a business - be careful !

Here's my baby - 20V 10amps. I like the MPG to for setting, accurate and not at all twitchy. ATB MM

Hi LaseCo, I never expected it to be simple, quite the opposite, but that makes it much more fun. What's the point in doing "simple", the satisfaction is much higher when you do the difficult :D Parts came back yesterday from anodising - look great. I'll post some pics later and then start...

Fiddy's spot on. Also, alot of these chargers pulse the current, sometimes 2x the rated charge current at ~50% duty, so measuring the just voltage can be very misleading.

1st try at taming the red didn't work - different optics to order ! The MPG has done some more programming though, so at least some progress. Hope to get the anodising before Christmas, photos when done. ATB MM

Small brick or a piece of paving slab- these have much less chance of giving off a "beam" reflection and will handle a lot of power.

I've also ordered parts from DTR, Flaming and Laseerer and I agree, they've been superb. Deffo, "prefered suppliers"
