Post DIY dolly: Interesting ebay item: 4 foot linear stage
Saw this and thought it might appeal to someone. Ends Aug 22nd 2011.

Linear stage.
48" of travel.
I maybe wrong, but I'd guess that the lead screw has a pitch of approx. 1" per turn. That means 48 turns to get shuttle from one end to the other, requiring 9,600 steps of a standard 200-step stepper motor. Strikes me as well spec'd for time-lapsing.

Hot, shame it's not in the UK, would probably cost a ton to get that shipped over here. :(

Ill bet that thing weighs a ton, for a shorter rail i think something lightweight would be a better choice, might as well make it light and portable if it will be under 6 feet.

Im sure it would do a great job though, i was looking at stuff similar to that when i was designing Chronos.

Is ebay becomming way to expensie for peope to run ebay businesses? Ebay seems to continue to raise fees and charge fees for things they didn't in the past. They own paypal as well and now rape you on paypal charges. I know in the past some people ran ebay businesses I'm wondering if it's getting harder to make money or even possible to make money anymore?


I know as a 'normal user', you get charged 10% on the final selling value (might be less for high value items). Then you get an additional 4% (or so) charge from paypal, its rediculous. If can make selling items a waste of time, hopefully more people will start using gumtree or similar
