How to Make (almost) Anything

Week 13: Networking and Communications


1. Following the Example
2. My Own Design

This week's assignment is to build a wired and/or wireless network connecting at least two processors. For my final project, I needed to connect four parts to the interface so I decided to start with the Neil's example serial bus boards. I was going to modify it to connect four separate boards (the input devices) but I haven't gotten around to make my own board yet.


1. Following the Example

My soldering skill has improved quite a lot over the course of the semester. For the Neil's serial bus example boards, I was able to program the two nodes on the first try. When I tried to program the bridge board, I got the dreaded "initialization failed, rc=1" error but I was able to fix it by resoldering leads of the processor.
