I have two of these and 2 motor drives that mirrors can be connected to.
I have no idea of their worth?
They have been sitting in a box in my closet for when I have time to build a laser project, no time yet so time to go.
Any offers or suggestions of value?
They were tested when I put them away but I can't find the power supply so they are as is.

Probably ~$10 each on the lasers

The stepper motors will be whatever you can get **IF** you can find someone that wants them

Peace,

The HeNe's are nice, but not too valuable on these forums. I would try Ebay. As for the motors, they don't look like stepper motors, but rather very low RPM DC motors (these types have a special name that I don't remember). These motors are good for lumia wheels, but the ones I bought had burnt out somehow. Those motors could be worth $10/piece if they work and the RPM is 0.5-1.

Also, if you want to put them for sale in ebay, please check them first.

I mean, maybe is just my impression, but in the pic, the capillar tube of the laser in the bottom looks "bent" (displaced, not in the center of the tube), opposite than in the tube at top ..... and if so, the tube is broken.

LOL! Picture right in front of me and I didn't see that :yabbem:

The bottom one definitely looks broken

You guys are correct, it is broken, I hadn't noticed it but when I turn it side to side there is a slight piece of glass inside.
I would sell the one good tube and both motors for $10.00 plus shipping. I hate to throw them away.

Seriously, you would make some more $$ on ebay. I already have 5 of those tubes, so I don't need any more. If the motors worked for sure, I would gladly give $10 shipped.
