Better laser guide mod?

Thanks! Found them that way. I searched those terms on mcmaster and figured I must have the wrong name!

Not sure if its the right size

Thinking about trying to fab those mounts the reviews were not very good… And they’re not really that cheap… I should be able to make them for at least twice as much money and 8 more hours! :slight_smile:

I too was wondering if those held the lasers secure enough, or were they just fiddly.

On Amazon…

No, no,no, just a simple switch will not do for me …Built a quick-n-dirty 555 “one-shot” timer on one of the circuit boards I made for another project. Depressing the button will trigger on the two line-lasers for about 30-secs. I’m impressed with how well my Crossfire is dialed-in, that 16g aluminum cover was cut with virtually zero dross and those 1/8 holes look like they were drilled (31A, 150ipm, kerf 0.025") …did i mention how much I love this machine?? :rofl:

Here are two “one-shot” schematic diagrams drawn in “CletusCAD”. One uses a push-button and the other, well, you can get really cool and use a touch-plate
EDIT Sorry, the unidentified cap is 10nF

I was wondering if you were driving a relay, but the 555 can handle the current of the lasers I assume? Nice! I couldn’t find the current requirements on the laser amazon listing…

Ya Cletus listed that. I was thinking of making them as the reviews are not too good.

Yup, the ones I ordered are rated at 5mW, I do have a few 5mW spot lasers here in the shop and they each draw 20mA @ 5V so a couple of them should draw no more than ~40mA, the 555 can source/sink 500mA

EDIT Kinda like the touch-plate thing, so I implemented that as well (too much time on my hands this week) :rofl: :beers:

How are you going to power it?

A 5V 1A wall wart.

EDIT: Yee gads, Torch firing certainly triggers the touch-plate, no biggie I guess! :crazy_face:
Not going to lose any sleep over it… reverted to the first diagram!

Well the lasers arrived today, and only one holder. My stupid fault, somehow, I only ordered one. so here I am waiting again. :crazy_face: :tumbler_glass: :tumbler_glass: :tumbler_glass:

Well, I’m an impatient old fart, so I McGuivered a little something in the interim. This laser cross-hair implementation is pretty damned neat! :rofl: :beers: :beers:

Looking at that I wonder if it’s not a good enough long term solution? The reviews of the amazon mount weren’t great how did you find them @Cletus ?

I am tending to agree with you @ScottNH . I find the commercial mount pretty iffy, whereas mine I’d say is pretty solid.

I think once you’re happy with the alignment, a drop of crazy glue on the balls, locks everything in place nicely. Then, if you really need to move it later on, a bit of force, a heat-gun or both, will loosen it all up nicely.

I would definitely avoid crazy glue on the balls. :rofl:

Here’s my version of the laser crosshairs for my Crossfire Pro:

The lateral lines on the aluminum are reflections and not coming from the lasers. What I particularly like about this is the lack of glue on balls, whether accidentally or purposely :grimacing:
