Qdeathstar:
Inspired by robin and sane day delivery by amazon!
I now have two of them !
The original one I ordered actually arrived at Argos (click and collect) on 9 August after I had got a full refund. The seller was happy (I think) to let me have it at a considerable discount rather than go though the hassle of having Argos send it back to him.
I was in two minds whether to take it but I reckoned I would never get that collection of parts at the price on offer. I am slowly constructing the second one in between other jobs - including writing a Python program that will write Openscad code.
The one I got from Amazon is the smaller 1610 version and I was surprised (and pleased) to discover that the slide bars on the 3018 are 10mm diameter compared to 8mm on the smaller model. At some stage I plan to do some tests to get a sense of which one is stiffer (i.e. more precise).
i just got the x table built and one of the y pillars up before i had to stop fro a while.... about an hour. Went together super easy i was suprised the spindel holder is some sort of formed plastic and not 3D printed.... i bought some PCB blanks so that’s probably the first thing i’m going give a go... wonder if can make it do two sided pcbs...
The build quality on these types of things is a lot better than it was five years ago... not exactly the same thing, but i bought a replikeo 3D printer and the buold quality was atrocious... they used all thread as a lead screw...
Hi, @raymw be very careful you don't put the ribbon, where it is coming out of the display, under any stress.
I bought two of these and only one would work if the flex strip was positioned in a certain way.

Thanks for the warning. It probably needs putting in a case, if only to keep the bottom of the pcb away from any metal, bare wires, etc. (My Unos, I double sided taped an old credit card on the bottom! They are about the right size, and have rounded corners.)
I read about a random number generator somewhere, that used a lava lamp and a camera. The number was generated by the positions, shapes and sizes of the blobs. That would be cool. Wouldn't even need to be a camera - perhaps just put light detectors all over the glass surface.
I admire the marketing guys that conjure up those products. I don't think I have ever come across anyone who actually needed more than 3 of the types in the collection - and then only after keeping it for years and running out of one type within 3 weeks
