Open enclosure designs
Design a printable case, battery holder or headband mount for an open PiEEG-family board. Share STL + source files under an open licence.
Possible Outcome
Files on your GitHub or Thingiverse.
You own what you build. Publish it under your own GitHub account with your name and chosen open-source licence.
Why It Matters for Open Neurotech
Good mechanical enclosures protect boards from electrostatic discharge, strain-relieve electrode cables, and make wearable experiments comfortable.
Starting Points & Technical Notes
These are open-ended suggestions, not specifications or assigned tasks. Change the scope, combine ideas, or take a completely different approach:
- Provide both print-ready `.stl` / `.3mf` files and parametric CAD sources (`.step` or FreeCAD/Fusion files) so others can remix them.
- Include snap-fit or screw standoffs, clear access to electrode headers, and strain-relief channels for leads.
- Specify recommended print orientation, infill, and filament (PLA/PETG/TPU).
Independent Open-Source Work
PiEEG Ltd does not take on volunteers, interns or unpaid workers. Any project you start is your own independent activity under your own repository and responsibility. Read the full ground rules →
Safety First
PiEEG devices are not medical devices. Use battery power only when electrodes are on a person, and never connect to mains power during recording. Liability & safety →
More Hardware & Analog Ideas
Independent noise & CMRR characterisation
Measure input-referred noise, CMRR and channel crosstalk of an open PiEEG board using your own setup, and publish the method so others can repeat it.
Active-electrode front-end prototype
Design an open active-electrode (buffer at the electrode) board that plugs into an existing open-source EEG front end, and compare it with passive electrodes.
Shielding & cable study
How much do cable length, twisting and shielding change mains interference? Run simple, repeatable experiments and document the results with photos.
