 +==== Open Beam Interface (digital acquisition) ====
 +
 +Use [[https://git.fa-fo.de/fafo/jeol-t330a/src/branch/main/obi/microscope.toml|microscope.toml]] from [[https://git.fa-fo.de/fafo/jeol-t330a]|our repo]]. There's also a obi.nix next to it to build the OBI codebase on Nix.
 +
 +Connect the OBI to power (currently through bundle of DIN SMPSes next to OBI), connect the OBI to the WHLE-LSE-1088A box via USB (or connect directly to your PC and run your own obi-server, after editing microscope.toml). Run GUI against microscope.toml.
