What servos did you use? The ones I have move at about 60RPM. No way fast enough to do even a simple vector graphic.

THis is why you use a mittor. If you do not know what that is, it is because I made a typo. It should be a mirror.

Shooting at a mirror ensures maximum effect, you can hit the very angle where.. well you know. Please don't ask me to drawings etc :D

You can also just place the laser on the servo - but make sure that the emitting bart is sort of at the axle. And then get some distance, like at least one meter.


However. I know you have a lot of servos laying around unused. THis is what I would have a look at in the theme of next week (This week being sunshine-week). Personally I think you should make a tirdnkwiit-kind of project; Have some fun, do some snaky stuff that you have no clue will end up with.

tirdnkwiit's are fun - I want to play with mine, but have to make ##Q€(/!! tutorials.

Hmmm... I see why you'd use a mirror, but don't you lose and awful lot of resolution that way? Like you only have about 2 degrees of movement in your servo!

"Mirrors." Those are the things used for looking at your self, aren't they? I know nothing about them.

I see what you mean, but then just do not point the laser at the very axle, you see :)
