Here’s a quick update on the PFC2 costs and maturity, from the creator’s forum at: http://forum.openag.media.mit.edu/t/pfc-2-0-beta-materials-cost-2914/1299
Incomplete BoM cost: $2914.38.
Add to this some custom assemblies:
LED lighting assembly,
PCB for sensors, etc.
The project is getting more expensive and complex than originally thought. I have wondered if their personal food computer architecture (HW and SW) is intended to scale to warehouse sized ‘farms’. This would explain the added cost and complexity, over what is required to simply automate and document growing some salad.
As such I’ve decided to watch that specific project (PFC2) from the sidelines for the near future.
A much cheaper and simpler offshoot is in progress. It it’s discussed on the same forum here:
That also uses a raspberry pi and Arduino so the parts I bought can be used again. I’ll post here if I decide to run it up. However currently I’m working on other things.
