Dashing Widget: Red Green Meter

A modified Meter widget that sets the background colour to either red or green depending on a threshold.

To use it, use something like this on your dashboard:

    <li data-row="1" data-col="3" data-sizex="1" data-sizey="1">

Dashing Widget: Time Since Last (Red Green)

This is a modified version of the Time Since Last widget by hannesfostie that is a bit simplified and with the red-green inverted (goes red when too much time has passed).

It does not use HTML local storage (no need, the server remembers it for us) and the threshold is just called 'threshold' and it is in hours.

8GB USB Digital Silicone Watch

Video teardown: https://www.youtube.com/watch?v=4uUUDYiGjno

USB Interface

When I plug the watch into the computer, it appears as a single USB MicroSD Storage device with idVendor=05e3 idProduct=0741. Nothing stands out as interesting, just a standard IN and OUT endpoint.
