The TeensyNet started as a way to monitor and control several fermentation chambers and beer storage coolers that I have scattered throughout my home. I wanted something that could be used either stand-alone, or controlled over a wired and / or wireless network.
Using a Teensy3.1 mini-board and a WIZnet WIZ820io board, I can now do just that. For wireless, I use TP-Link TLWR702n and TL-WR703n wireless client adapters.
I also have a complete Linux environment setup on a Raspberry Pi that can find, interrogate and control all of the TeensyNets on my intranet via a LAMP setup and UDP.
