This is a detailed post on how to get your fridge to autonomously order fruit for you when you are low. An RPi takes a picture every day and detects if you have fruit or not using my Caffe web query code. If your fridge is low on fruit, it orders fruit using Instacart, which is then delivered to your house. You can find the code with a walk through here: Some of my posts are things I end up using every day and some are proof of concepts that I think are interesting. This is one of the latter. When I was younger, I heard an urban legend that Bill Gates had a fridge that ordered food for him and delivered it same-day whenever he was low.
Hacking up an Instacart API The first thing we need is a service that picks out food and delivers it to you. Head over to instacart.com and set up an account and login. That string is what you need to access your instacart account. Curl. Raspberry Pi + OpenCV. OpenCV is a suite of powerful computer vision tools. Here is a quick overview of how I installed OpenCV on my Raspberry Pi with debian6-19-04-2012.
The guide is based on the official OpenCV Installation Guide on Debian and Ubuntu. Before you begin, make sure you have expanded your SD card to allow for the install of OpenCV. Its a big package with lots of dependencies. You can follow my instructions here. Once you have expanded the SD card, open up a terminal and install the following packages: There are some dependency issues with the order of the install, mostly with regard to libjpeg issues, so be sure to install in this order. Next, pull down the source files for OpenCV using wget: wget Once finished downloading, extract the archive, remove the no longer needed archive (to save space), change directory to the top of the source tree, make a directory for the build, and change into it: cmake-gui ..
