Hiya - This is an eBay listing for a huge lot of Lego Mindstorm parts, possibly from one or two kits. I'm selling these for a friend who filled a whole closet with Lego stuff. Most of the items in this kit are unused and are still in the original bags. There's quite a few motors, two 'smart bricks' (NXT and Ev3) and several sensors. There's enough parts here to build probably anything... Cupcake CNC machine? Maybe, but don't hold me to that. Feel free to shoot me over questions and requests for info on specific parts, additional photos, fashiun advice or just to chat... Thanks for looking!
