This week, we’ve started prototyping!

We ordered a few components, such as:

  • pH sensor
  • battery
  • storage box (TODO)
  • solenoid

CAD designs have started for the mechanical components, such as the housing. The following are a few images of the GnoMini CAD:

In terms of software, a first prototype of the backend server has been completed. We also did some planning for the app component, and decided that a web app would be the best approach, with WebBluetooth used to connect to the Raspberry Pi. Work has started on a basic version of this app.

We also met with Prof. Khamesee and Prof. Pellizzoni to discuss our plans for the term.

Next week, we’ll start prototyping electrical components once our electrical parts arrive.
