I love the pomodoro technique mostly because it reminds me to remove external distractions, so much so that I built my own tool for it.

Planning to built a Pomodoro clock using Arduino... Some day :) I know there is a bunch of them available but hey nothing is more fun than using a device built by yourself.
I've used that and it's really well written, issues I had though where I work with headphones in (even at home) so I often didn't hear the tablet/phone where I can chuck mine on a virtualdesktop off screen and just listen for the notification noise (it also does desktop notifications on chrome).
An arduino one with a nice dot lcd and some kind of logging would be a kickass little project though, I might steal that as an idea :D

Itch scratching but I use it every day :)
