We decided to make a bread engraving machine using a soldering iron. It's purpose was to engrave bread using a soldering iron as an end effector to create a sort of custom toast. We had initally thought about doing some sort of hotwire cut toast but settled on the engraved toast as a somewhat novel way of producing some interesting patterns.

My contributions were mostly software, however I did turn a new soldering iron tip on a lathe so that there was a somewhat clean tip with which to engrave the toast with.
