@k8ik has built an STM in the past and we want to get it back up and running, with the goal of eventually improving on the resolution it can achieve. The first step here is to achieve basic imaging in a laboratory environment.

Project homepage is at https://wiki.fa-fo.de/projects:stm and a repository with technical documentation can be found at https://git.fa-fo.de/fafo/k8ik-stm.
