Bean sorter: The opto-rack for the raspberry pi arrives from China

This opt-output rack I bought from China cost less than $17. They used to cost an order of magnitude more than that. It is kind of sad we do not make them so much anymore in the US, but it is a very good thing they are available at so a low price and that we do not have to make them as low cost items with thin profit margins. This is the last piece of hardware I needed for hooking up the control to our coffee bean sorting project, but I have had two other projects take priority (involving clinical trials and compliance issues–that is a good thing because the trials and compliance issues would not be needed if the product did not work). So I am going to have to sit and just look at this fun new toy for a month or two before I can hook it up and make it do its thing.
