I've created a how-to guide on how to build the TIRO watch over at Instructables.com.

I had fun making the guide as it allowed me to go through the steps myself and contemplate about my design decisions. It was a lot of work though. It's a good thing that the project is not that complex.

I've mentioned this a couple of times already, but the next step for this project is for me to redesign the circuit by using SMD components. This will result in a smaller watch. This is my first time doing this though so I might take the time to learn and research about it first.
