• Finally christmas

  Finally we have some time to continue with our project, we have already written a few lines of code and designed a bunch of concepts for lattefy.

  This are some concepts we have been making, developing with each iteration a more simple design easier to build.

  We have already bought the hardware we need but unfortunately it hasn't arrived yet so we have been working on the software, but not having the hardware to try our code makes it a bit difficult.

  The code we have written is divided in two child functions, one which checks pushbullet and another that listens the physical buttons, and a father process that processes the signals received by the child functions. Whenever you ask for coffee by pushbullet or by pressing the buttons on the control panel a signal is sent to the father process which then makes the coffee you ordered.

  We just bought the coffee maker and we took it apart, this are the parts that we need (they are all shown in the picture):

  Pumping and heating system

  Temperature switch

  Water tank

  Now we have to measure everything and buy the parts that we need, then we will be ready to start building the prototype.
  

• Starting to code

  At first we were planing to use Twitter as the communication system between Lattefy and other devices but after some problems with the API and after thinking that it wasn't secure enough, basically anyone could send a request to Lattefy, we decided to user pushbullet wich is a bit more secure, communication between devices is private and you have to know Lattefy's e-mail account to send it a request.

  At this moment the code, which can be seen in our github repository, is able to read messages and to answer them, components and complete functionality aren't decided yet so it can't do anything productive with your order.

  A request to Lattefy would be something like this:

  Requester: Coffee with milk

  Lattefy: *processes order*

  Lattefy: Order completed, you can pick up your coffee with milk

  This is an actual "conversation", in spanish, between Lattefy and me:
