I am a bit confused with these pictures.

What are the zip ties wrapped around besides the laser? The pdf says “Zip ties to hold laser to bar under the supports” but I can’t see a bar and there are no pics of the underside of the mount.

Is there just a short piece of metal or something that I can’t see in these images?

I’m guessing theres a bar (thin piece of metal?) that runs perpendicular to the supports. The zip tie runs around the bar and the laser. The silver supports are sandwiched in the middle and hold it all in place. Just a guess…

Nice!  Mmmm Laser cut holders. rasberry That should give you plenty of adjustment and freedom for lense rotation.

I just hope that my plans have the correct size, or I’ll have to laser cut the supports with a Dremel smile

You need to make sure that the centre line of the laser module is at least 1mm above the surface.

My acrylic is 6mm the module is 13mm Diameter so the centre line naturally sits about 1mm above

Have fun!

Ok, that’s what I have : 2mm LCD matrix + 3mm Acrylic, so the beam should be 1 or 2 mm above the Acrylic surface.

Thanks so much for this. I just got my lasers and am wiring them up and was dreading the process of getting them “perfect”. I’ll be following these instructions and report back on how it’s going smile

Hi

You dont need the laser module blanks (3rd item)

You should get 4 850nm Lasers each with a line generating lense

The output depends on the size of your table/setup i have used 10mw lasers which are just about powerful enough but in hindsight i would have perhaps gone for 25mw, (price was my enemy!)

As for a power supply, RS, maplins, etc all do 1000ma adjustable voltage supplies which can be set to 3.2v(have a range typical 3.2v upto 15v) this would be suitable to run all four in parrallel.  Its probably cheaper to buy an adjustable supply than a fixed 3.2 at 1000ma.

Hope this helps. rasberry

850nm is best!

and i use 120deg line lenses but a 90deg fan angle in all fours would just about cover it in IR.

I didn’t try this yet, but it is possible to make something like this or the acrylic/projection surface diffuse the laser?
