Default knob tripod.

I was thinking, now this is a longshot here, if I hook up the same mechanics from an etch-a-sketch, (the knobs move the spot) if I could use that to more precisely aim lasers being held on a tripod. Currently, I'm disassembling an etch a sketch I picked up at a dollar store to extract the pieces. If anybody has any experience with a similar mod let me know. Also if I can find a good relatively cheap tripod I might sell these modded bad boys at a later time once I figure the best way to assemble it.

Stay crunchy.

I'm confused as to what your trying to accomplish. Are you trying to turn an etch-a-sketch into a kinda mini manual cnc machine? Turn the knobs to burn a design into some material?

Yeah I would like to know too. Just last night had this idea of taking apart an etch a sketch and using the parts inside for a mini cnc.. or at least use the parts as a template for a larger one.

the hell is a cnc?
I'm kinda new to lasers but have a vague background in simple mechanics.
What I want to do is turn a tripod into a tripod that can be moved on an X and Y axis via the use of 2 knobs, similar to how an etch a sketch moves the drawing pin on an X and Y axis. This would be used to finely move it, perhaps used in high exposure pictures to write things.

CNC's are machines (usually number controlled), such as laser cutters.
