There are swivel mounted mirrors out there with a coil already on
them which can be modulated to hard point or oscillate the mirror
angle.

I used to put \'music\' up on the ceiling with my HeNe laser tube, and
two such mirrors.

Hi

I am working on a project, just for my own business

I need a laser marking system, that can show a cross hair or other visible marking on a cardboard box up to 4 meters away

Initial thought would be class 1 laser (no approvals?) and then 2 steppers in a mechanical arrangement to provide x and y
functions

I can add a USB camera to home in the laser, so the mechanism does not need to be precise

Any hints for the cheapest system?

Maybe using the optical drive for a cheap projector?

I need to be able to buy it for my own production
Use RC servos and 1 PIC micro
red laser diodes are cheap on ebay.
http://panteltje.com/panteltje/pic/camc_pic/

Or you could get one of those xy movable video security cameras and put a laser diode on it.
Wrote a controller for mine long time ago.
Then you have the camera pointing at the target all the time.
https://www.ebay.com/itm/324772560866
That is actually a very nice idea. Kills two birds with one stone

I then need to find a camera with an open SW/library. How did you go about finding the documentation for controlling them?

There is some history to that, I wrote soft for my first IP camera:
http://panteltje.com/panteltje/mcamip/index.html

The way I hacked that is by looking with \'snort\' (monitors IP traffic) at what the web browser with their software did send to it....
They, D-Link, were a bit upset when I reported the security hack/ leak.
Anyways when I bought that Chinese x,y cam I added support it.
Later I added motion control, wrote a program called \'xipcc\'
http://panteltje.com/pub/xipcc_setup.gif
that can move the camera left right up down.
That Linux xipcc code is not on my site, but you can have it if you want, is basically open-source,
you could modify it to move the camera auomaticaly, for me it was just a quick hack so I could point the thing.

Let me know if you need the code, then I will make a .tgz and put it on my site, is all Linux C though.

I had my first LaserDisc player and when I got my new player since
the first was acting up after being in an upright arcade game for a
couple years, I took the old one apart because it actually had a nice
little light table inside and a HeNe Tube laser and an HV power
supply to excite it with. I pumped 60 Hz sine into one and music
into the other and made lissajous on the ceiling in my bedroom back
in \'91.

5 tube 3 inch scope? On the scope face? This was on the ceiling
above the laser table.

Oh and \"on the high end\". You\'re not even close to the units the
rock bands of the seventies used, much less what they are using now.

Ok. I used lasers to make \"scope traces\" project. You used a
scope? No projection just look at the pretty lines on the scope
syncopate to the music? My first week in the electronics lab. 8
years later.

So when you were 60 you went senile and angry, because that is how
long you have been posting senile angry horseshit into this group.
Were it not for that, you might actually be considered a group

WelI have seen lost of that stuff in the studio.
And that laser videodisc, Philps asked me to write the service manual.
Sure I had the HeNeon laser too at home.
And then, in the seventies we had holograms, I still have one somewhere.
Rock bands these days? Are not there only rappers these days?
As to politics, you failed here spectaculary.
Now go back to yer mama for breastfeeding.

Yes, but RFC977 is from 1986, and was obsoleted by RFC3977, which was
later updated by RFC6048, and so on...

Brackets are a good idea these days.
