aegir
Aegir, beside being associated with the oceans mainly, was also the brewer for the gods of Asgard.
This project aims to create a precise brewing platform using industrial-grade tools, based on Raspberry Pi3, and FreeBSD.
So far, the project is still heavily in development, not suitable for use, not even for testing.
Project goals
As it can be seen from the part list from the project wiki, one of the goals is to utilize industrial-grade tools for the homebrewing process, trying to still be within reasonable financial limits. Probably the best example is building on T-type thermocouples with SLE (Special Limit of Error) cabling, which provides a quite decent error range of +- 0.5C.
For the initial development, the goal is to make it work in a 1-pump RIMS setup, without PWM valve controls
