Internet 0 / Zero - Milling, Stuffing & Setting Up the Boards

by Anna Kaziunas France

I0 The Fab Academy Assignment: build a network with at least two nodes The Project: Internet 0

Progress so far:

  • milled out boards:
  • 2 leaf nodes
  • 1 serial board
  • 1 hub board
  • made cables
  • stuffed boards
  • flashed all boards
  • tested network

Tools Used

  • Modela milling machine
  • Python Cad

Individual Boards / Boards in Stages of Completion

I0I0I0 Network Operation: I could get the leaf notes to respond to each other. When I pressed the button to connect node 1 to node 2 and vice versa - the LED’s would blink on the opposite board.

The setup went smoothly until I tried to view the IP addresses over the computer via the serial board / port. At first I thought it was the serial board - perhaps there was something wrong with it - but after much troubleshooting, I couldn’t find anything wrong (except it didn’t work). I then tried using an echo board that I knew worked properly, but still not communication with the computer over the serial port. Shawn, Makeda and I worked on it in the lab for a while, but nothing came of it.
