The Food Computer is a controlled-environment agriculture technology platform that uses robotic systems to control and monitor climate, energy, and plant growth inside of a specialized growing chamber.
For more details check out this pagehttp://openag.media.mit.edu/hardware/
See our TED Talk.
The plans are all open source (see latest release - Personal Food Computer 2.1
See our Bill of Materials (BOM) on our GitHub.
Yes! The code and hardware plans are all open source.
Please see the Personal Food Computers page for info on all versions of the OpenAg™ PFC.
The Personal Food Computer v1.0 was our first go a the problem of creating an open source tabletop growing chamber. It could run limited environmental recipes for light and nutrients.
The Personal Food Computer v2.0 was a next-gen system. It included:
The Personal Food Computer 2.1 is the latest release, and an evolution of the PFC v2.0. This release includes a new light panel and the latest release of the openag_brain v1.0.0. It has several updates and many bug fixes.
The MVP 1.0 is a minimalist Personal Food Computer developed by OpenAg Community.
See Climate Recipes.
There are lots of kinds of hydroponics. You can drip water over plants, mist the plants, or use soil.
There's some vendors who sell kits based on the open source materials available. They're not affiliated/endorsed by the Open Agriculture Initiative at MIT, which is the academic research arm of the OpenAg community.
Lots of things! Leafy green and herb are good first choices. They are fast, easy to grow and fun. We've grown lots of plants that are frequently grown hydroponically (basil, tomato, chard, kale, …) and a lot of plants that aren't usually grown hydroponically too. Join the experiment and see if you can grow your favorite plant!
It depends on the plant. Many leafy greens and herbs take 2-3 weeks to grow from seed to full plant. Tweaking the Environmental Recipe can also cause faster plant growth, more leaves, and different tastes.
1-2 experienced makers can source and build a Personal Food Computer 2.1from scratch. The OpenAg Community Forum is a great place to ask questions, source alternative parts/materials, and follow along with other nerdfarmer builds.
We like to use food-safe bins and safe fertilizers so that the plants we grow are edible. Yum!
Of course, the Food Computer is open source, so safety is up to you! Make sure to use clean water and food-safe materials/ingredients if you plan to eat your plants.
Nope! There are folks all over the world building Food Computers, and we welcome contributions from anyone.
The forum is a great place to start if you have a question.
Troubleshooting or doing development on a Food Computer? Check out development for tools.
And, if any mods are possible, how to upgrade the v1.0 to the v2.0?
(i.e., not Linux/RPi but on OSX/Windows)?
Check the output of dmesg right after you plug in the camera. If you see something like:
[1648506.064410] usb 1-1.2: new low-speed USB device number 8 using dwc_otg [1648506.164390] usb 1-1.2: device descriptor read/64, error -32 [1648506.384347] usb 1-1.2: device descriptor read/64, error -32 [1648506.604409] usb 1-1.2: new low-speed USB device number 9 using dwc_otg [1648506.704412] usb 1-1.2: device descriptor read/64, error -32 [1648506.924382] usb 1-1.2: device descriptor read/64, error -32 [1648507.144360] usb 1-1.2: new low-speed USB device number 10 using dwc_otg [1648507.584367] usb 1-1.2: device not accepting address 10, error -32 [1648507.684377] usb 1-1.2: new low-speed USB device number 11 using dwc_otg [1648508.124522] usb 1-1.2: device not accepting address 11, error -32 [1648508.124603] usb 1-1-port2: unable to enumerate USB device
then it is likely that you need to switch the two data pins on the white plug that attaches to the camera (they should be the two middle pins)
