AeroElectronics/Open-Source-Electron-Microscopy7This is not the first or last attempt at making open source electron microscopy a reality. Many others have attempted this large and difficult task before with varying specialties and contributions.
Inductor board is an open-source printed circuit board by AeroElectronics, from the AeroElectronics/Open-Source-Electron-Microscopy repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 2-layer board of 275.5 × 90.6 mm with 220 parts on 298 nets, routed with 1,468 tracks and 107 vias.
It is built around the TLP175A and L7805. Its parts include 65 resistors, 33 ICs, 18 switches, 17 diodes and 16 capacitors.
This is not the first or last attempt at making open source electron microscopy a reality. Many others have attempted this large and difficult task before with varying specialties and contributions. I have learned a great deal from other's work in this area and it is my hope that I can make a contribution too. It is through the collective effort and ability of the open source community that progress on such large and difficult tasks may be realized.
My work so far has focused on the control electronics which can be used to drive electron microscopes. This is an essential first step that can (mostly) preceed the design of the electron optics. I'm hoping that by lowering the barrier to entry, others can work on this exciting task.
Note to readers! This repo is quite new, many of the currently uploaded works are my most recent iterations (old designs have not been uploaded) and have not yet been tested. Please check the
I've worked on a few areas, see the links below:

Wireless enabled power switch for desktop PCs.
It measures 275.5 × 90.6 mm and has 2 copper layers, 1.6 mm thick.
220 parts, built around the TLP175A and L7805. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the AeroElectronics/Open-Source-Electron-Microscopy repository on GitHub, at the commit this page was made from: the board is SubstitutionBoard/inductor_board/inductor_board.kicad_pcb and its schematic Backplane/backplane/backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
