2020-08-17 Thank you all for your great feedback! I will incorporate some (minor) design changes this week to implement those improvements. It would be great if you could let me know, how the "00 Tester" parts work on your printer! Thank you
Remarks - Please Read :)
Even though I went through several iterations, the parts might need to be change in the future! The build instruction is available here: https://en.openscan.eu/openscan-mini
The scanner works with the existing OpenScan Pi Shield (see: https://en.openscan.eu/pi-shield but you could also use a plain Raspberry Pi + breadboard with the existing pi-image provided on my website.
