RGB hand-held laser






wow what a nice addition, this angle control! I can only imagine what may be next:
How about some type of speed detection of your waving it thru the air that would control a strobe rate of the lasers..or even this with the lasers being 120 degrees behind each other so that you could then in turn make the colors flow depending on the speed you spun it around!.. the things you could probably do with that are endless!
Good job! thanks for sharing!
I liked the look before anodizing though, those squares for grip on the handle looked so perfect - and everything else, like the corners (with a sort of pattern) of the cover over the LCD
 
1st baloon pop and you saw it first on Laser Pointer Forums:beer:
(Wife wasn't impressed :evil: - should have given a her a warning:crackup:)

 
Oh no, the wifey will have your nutski. be careful my sir! XD
+Rep if i havnt already. You deserve to be a top builder here.
 
Multimode, I noticed in the pictures a few posts back of the beam being swept over the ground, the output appears to be pulsed at a high frequency? Is the driver circuitry the cause of this? Or interference effect of some sort? :confused:

And, if you aren't going to make units for sale, would you consider a build tutorial?

Hi T,

The PWM frequency of 1 of the channels is 1/2 that of the other two - I fixed that in the software now, but havent uploaded the newer version - few more things to do first.

The effect could also be due to the speed the laser is moving?

I'm looking at making some more - I do have 3 or 4 sets of the machined parts and PCBs - But I want to sort the wide red first, the photos reduce the effect of the wide red, but in person its very noticable :cryyy:

edit - I just read you Q again. the dots are due to the PWM- If the power is at 50% then the laser output will have a on / off ratio of 50/50.
I'm looking at increasing the PWM frequency to make the beam dots overlap - you don't see the dots unless you move the laser quickly. However, the beam effect looks good, so I'm going to have a mode to make this more visible !

How much would the PCB and machined parts cost? I would buy a set in a heart beat. :)

Hi Multimode:

Was wondering if the beautiful key switch cover was machined from a single block of Al or if the laser symbol rays were soldered or welded on?

Other thought was a flush mount or different design key switch would better preserve the beauty of the design--if something other than standard barrel key switch is available.
 
I'd guess machined, it's too precise to be welded, also you can see it in 3D render exactly like it. CNC machine won't complain about details :p Might as well use that.

Spot on Eud,

It's machined out of a small billet.
Roughed using a 10mm end mill with 1mm corner rad.
Then a 6mm ball nose and finished with a 2.0mm ball nose.

It's just a cover that hides the mirror mount screws, TBH it would be much easier to have the key sw on the back end and that would simplify the wiring.

Prety much the same method to machine the LCD cover - you're right about the machine not complaining about the detail, it just take a bit more time to mill.
