Crosshair laser

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
