Glad they made it OK David,

Is anyone else interested in the other set? THe ones with the big mirrors?

[jordan200]

I think I have 4 at home, I will check. I would prefer to sell as pairs though.

Does this interest you?

This is my first time to see such big one!

Are these considered closed loop? Woudl they work with any driver board? Those are beastly mirrors! Easy to align on? :roll:

[QUAZAR]

These are open loop sacnners, they can be driven by almost any simple amplifier circuit. The mirrors can easily be changed for something smaller. Using the schematics below, you can actually build a simple analogue controller. A fun project that wont take long and is very cheap on parts.

I see. They're kinda like these I got of eBay.





I had em hooked up to an old Laser FX that I disected and bounced my lasers into.

That was cool for about 2 or 3 months... Now I got some scanners and am waiting for a DAC... :roll:
