TMImachine was built at The Stupid Shit No One Needs & Terrible Ideas Hackathon 2015 at Noisebridge, San Francisco.
With this code, a CloudBit and a pressure sensor from littleBits you are able to build your own TMI machine. Place the TMI machine with the presure sensor on the toilet seat. This will enable the machine to send a tweet about when and how long the visit at the loo was. See examle at https://twitter.com/tmimachine
