Source code and schematics

Currently dAISy is only partially open source.

The core of dAISy, how the Si4362 radio IC is programmed to receive AIS, is available on Github. While
the project does not include all the functionality of dAISy as sold, I do backport any bug fixes that are
relevant to the task of receiving AIS.

There’s also a long thread on 43oh that documents the journey of dAISy from its humble beginnings.

http://forum.43oh.com/topic/4833-potm-daisy-a-simple-ais-receiver/

If you want to mess with the real code, brick your device with custom firmware or even build your own
dAISy from scratch, please contact me.
