audio on a particular clock face simply press the encoder in and turn clockwise to increase and
anti-clockwise to decrease (the volume level will be displayed on the two rightmost E1T tubes).
You can also use the IR remote for the same purpose.
Clock Customisation
One of the core principles embedded in an Open Source device such as Fortress is the ability to
customise it by understanding how it ticks . Faces for the clock are written in a hybrid coding
26
language called ‘Nuggle’ and exemplary examples are provided in a separate manual called ‘The
Nuggle Cookbook’ available on the Dropbox. As supplied, the Fortress comes with a pretty
comprehensive set of ‘faces’ which combine both timekeeping, LED lighting schemes, solar
information, screen savers, and the occasional light-hearted audio chimes. All of these are
provided on the SD card and can be viewed and edited as needed. For a detailed description of
the standard Face Distribution set start at page 13.
Clock Care and Troubleshooting
Fortress is a pretty special clock and as such should be suitably cared for to enable a long life and
enjoyment for years to come. Please only clean the acrylic with a lint-free cloth (scratches aren’t
cool), and keep it away from prying fingers. There are high voltages employed within its confines
and even though it is well protected accidents can happen. The E1T tubes are very valuable and
(alas) a non-renewable resource, so please only operate the clock with the case top in place to
protect them from accidental contact and stray flying objects. As with most complicated
27
electronic devices, sometimes things don’t go according to plan. If the clock, for any reason,
28
doesn’t operate correctly, the first thing to try is a hard reset by turning the power off, waiting 5
seconds then turning power back on. Pulling the PSU socket out and plugging it back in isn’t
ideal as this can also lead to hanging the CPU, so please only cycle power using the switch on the
power supply. If that doesn’t fix things, then please try using the serial console (see Page 47) to
see where things are hanging up . If that doesn’t pinpoint the issue, then please contact us and we
will help you to get things up and running again. This doesn’t extend to failure of the E1T tubes as
these are obviously out of our control and have a finite lifespan. We will, however, warranty any
issue in the Fortress electronics due to premature component failure or faulty construction for 1
year after date of purchase. This does not extend to accidental events such as spilling drinks on
the clock or dropping it on a hard floor etc. This warranty also only applies to pre-built clocks
29
purchased directly from us. If you are having problems with kit construction we are here to help
but some costs may be incurred for such assistance depending on whether shipping the clock is
involved etc.

This may seem a little OTT, but as a favourite author of mine once wrote, ‘Scientists have calculated that the chances of something so
27
patently absurd actually existing are millions to one. But magicians have calculated that million-to-one chances crop up nine times out of ten.’
- Mort, Sir Terry Pratchett.
This should be a rare event.

Common sense should prevail here.
