wired/less networks
The focus of this week was to continue to expand on our electronics knowledge in the area of networks. This is quite a new and deep topic for me so I spent a decent amount of time reading and comprehending just how the many types of networks function while working on the hello wired network. The bridge board traces layout above.

A set up for multi- node board cutting.

Milling was a challenge this week perhaps due to the high volume board making. A few tips include being sure to vacuum the bed before adhering your board. Be sure to stick down your board as firmly as possible to keep the board from moving especially on a multi run board. Also be sure to use a razor blade and/or tweezers to remove and copper fuzzies between the traces. These tend to lead to shorts that are often unnoticeable after stuffing the board.

Burning the bootloader for a ATTiny 45 with an 8mHz internal clock through the Arduino IDE.

Programming the bridge. I ran into a few snags here. One was using a sparkfun usb to FTDI adapter that seemed to be buggy! Buy your own FTDI. Also the direction of your FTDI matters. (I think this photo was when it was upside down.. later flipped)
