When a stable prototype of the companion radio is finally designed, I would need an anonymous volunteer(s) inside Iran to help test and / or setup the device.
They would ideally be someone who is comfortable with wiring up some electronics and flashing some firmware.
If you are outside Iran, the best way to support the project would be by donating XMR. This disproportionately helps the project, since parts and resources are comparatively cheaper inside Iran.
You can contact me via my LXMF address for details.
