This project is great.
Last semester at university lab, our group tried to rebuild it in our lab.
Through our spectacular fail, we learned how amazing this project actually is.
It is harder than it seems.
One can learn very much about piezo electronics, especially about OPamp circuits.
And do not underrate the damping!

- FuriouslyAdrift 5y agoIn the section for "Electronics" is this line "I place a metal can over the STM during scanning to shield the tip and preamp. Without the shield, the images produced by the STM are dominated by 60 Hz noise pickup."
- jacquesm 5y agoAh! I totally missed that, thank you. I thought the pictures were of the scanner in operation, and that detail really confused me.
