My attempt at building a food computer.
I’m going to attempt a build of the old food computer, and probably the new one after that as well.
It would be great if people could point out my mistakes as I go along.
Step 1: Research
- OpenAg Wiki on Food Computer 1.0
- Another build diary on the forum
- Slack (Sign up here)
- Adrian Lu’s Blog
My understanding is to just look through the BOM on the gro-hardware repo and start buying stuff right now.
Will update as I go along.
Step 2: Buying Stuff
I’ll just start by buying all the stuff on the BOM on gro-hardware. I recently moved to the US so I need to get some tools as well, but I’ll leave those out since most of the tools look pretty accessible.
My concern was that the BOM looks incomplete in regards to the shell and mainframe.
There’s a github issue regarding this as well.
However, excel spreadsheets have multiple tabs/sheets on them. It took me an embarrassing amount of time to figure this out, the hardware/kit BOM is in separate sheets.
I went to Home Depot today and bought some more stuff. Realized 4’ x 8’ boards don’t fit in my car though, so I should probably do something about that. I noticed that the 2" Diameter standoff mentioned in the Mainframe Assembly Instructions weren’t really something you buy, I assume you use a hole saw on the remaining PVC board and cut it out?
Step 3: Assembly
Made some progress on the shell assembly today. I started cutting it with one of those retractable blade knives, but the cuts get dirty and it’s difficult to cut straight with them. I switched out to a circular saw and that worked perfectly.
Everything was pretty straightforward following the instructions on the PDF, cut the insulator to size, apply hot glue. I did run a bit short on the foil tape though, so I guess buy 2 rolls. The corruplast has yet to arrive, so I might do work on the Main Frame in the meanwhile.
