Re: 2-axis mirror controller

You can do at least as much (probably more) hardware control under Linux/BSD as you can under DOS/Windows environments. Timing will be more reliable under a UNIX environment as well.<p>I did note that you were talking about the parallel port; this won't be a problem at all.<p>Thanks for all the help...

Re: 2-axis mirror controller

Ah, I'd probably be using Linux to control this thing anyway, so QBasic isn't going to be useful for me. I've done electronics programming though a serial port in C before for a (I think) more difficult project.<p>Thanks for all the information!<p>Kind regards,
Devon

Re: 2-axis mirror controller

Our application just needs to let people see that we're drawing something with a LASER and make them think "cool" and dance harder. :) . The electronics guy hasn't worked in this sector before, but it sounds to me like all the problems (or features) are going to be found in the software I've got to ...

Re: 2-axis mirror controller

Grant,<p>Thanks a lot for the schematics. I have a couple of questions about them:<p>1) What is the precision to which they can control these motors - or, if more applicable, <p>2) What is the precision of control regarding the motors they *can* control.<p>This is really great being able to control ...

Re: 2-axis mirror controller

Bob,<p>Thanks for the link!<p>We're not doing something as precise as scanning wafers; we're trying to build a programmable device to control a couple of mirrors for LASER lighting effects (i.e. parties and dj stuff). <p>We're wondering if there may be lists of parts for this kind of project, perhap...

2-axis mirror controller

A couple friends of mine and I are interested in building a controller for 2 stepping motors, which would steer a couple of mirrors for laser lighting effects. Any pointers on kits/parts for this kind of project would be highly appreciated.<p>Thanks,<p>Devon O'Dell
