The Mäqädat team presented their latest progress at Maker Faire Hannover 2015.

Here's the prototype I've been working on lately. More details to come, but I wanted to point out the vacuum adjustment inspired by the Michigan prototypes. There's a clear plastic film wrapped around two adjacent tubes (one not visible in the picture). The visible tube is slotted and connects to the vacuum, and the film has holes cut in it so that it can be rotated to change the position of the suction area.

Di Fu and Yusheng Zou posted some videos of their work on Michigan Prototype 3. They are continuing to improve a prototype that they worked on with Yuwei Li and David Pawlak in the fall of 2014.

A video discovered by Hackaday April 23 shows another scanner build, this one using a server fan to provide suction. The photos show some great craftsmanship!

This is an impressive high-speed prototype designed by Gérard Tolboom, with firmware changes contributed by Matthieu Gros. Gérard made improvements to Prototype 1 last year and has now configured the same parts into a V-shaped channel for higher speed. He reduced the cycle time from 11 seconds to 4.5 seconds and demonstrates an incredible 1.63 seconds moving the book by hand.

Here's a cardboard model of a new design inspired by the University of Michigan prototypes. It will hopefully improve on the V-shaped channel, and will be laser-cut out of acrylic.

This is a great article published by University of Michigan about their work on the Linear Book Scanner.

At Maker Faire Hannover, a team in Germany presented an exciting new design for a linear book scanner, for use by Mekele University in Ethiopia. Their prototype is made of wood and uses the Coandă effect with blowing air rather than a vacuum to separate pages.
