Internet Enabled Coffee Machine

Next time you walk over to your coffee maker to turn it on jut imagine the time you could have saved if you had a Internet Enabled Coffee Machine. 🙂

“The goal of our implementation was to make the machine useable in both standalone and Internet connected modes. This means breaking into the push buttons and interfacing with the status LED. However the PCB within the machine floats at MAINS voltages. This is a potentially dangerous situation therefore one of the prime interfacing tasks is to create a totally electrically isolated inteface. We achieve this using opto isolators. Just before boxing the machine up, we made some final interfacing tests. The most important test is isolation where we checked that the optoisolators were indeed correctly connected and that there would be no electrical connection between the WebBrick and the coffee machine.”
