Crosshair laser

[rfranzk]

Here is something that is relatively simple and appears to work well. Check it out.

Being that uses a flexible tube to hold the laser, what keeps it from moving if bumped or from the drill press vibration?

Those goose-necks are pretty stiff, so I doubt he has a problem. That was actually quite educational. My initial response to the crosshair question was simply that it was the first thing I thought of. But now I've looked at that tutorial, I can see why I would prefer a crosshair. It's purely a matter of personal preference.

I think I'm going to PWM the module and reduce it's supply voltage too, keep the pulses narrow so it should minimise the damage it can potentially do to my eyes. I'll also experiment with shining it through something that makes it dimmer, it that method isn't enough.

I'll be sure to photograph and write up a full description of the drill when it's done

Good luck and keep us in the loop

Wish I could find the link again. But coolest idea I've seen for a PCB drill with laser was one that mounted the laser on the top side, then the drill came up through the table. The spindle was mounted below the table and was lifted by a foot pedal. The top mounted laser was just a dot aimed at the drill point.
