Hi Nick,
Sorry to rain on your parade. A good idea BUT ...
As a new (45 years) New Zealander may I make a couple of suggestions
that folks back where I come from and others across the pond forget.
The Pacific Ocean is large and very spread out. So the Chatham Islands,
though part of New Zealand are 45 minutes ahead of New Zealand time.
That is a real nasty and unusual time change. Plus NZ daylight time
being GMT +13
Next are the Islands making up Tonga. To keep the day consistent with
New Zealand, Australia, other Pacific Islands & Asia went to G.M.T. +13
as its timezone a few years back.
Cheers,
Will

I’ve finally added the power supply I’ve designed for the Thunderbolt. It’s a
combined switching+linear design. It’s been running my own Thunderbolt for a
while now. There’s a schematic on the store page and it can come with or
without a 15W primary supply.

The second one will be up next week, and it’s a simple GPS clock. It has 7 seg
LEDs for hour, minute, second and tenth of a second (the later is interpolated
from the PPS). My educated guess is that the tenths are accurate to around 200
µs or so (the zeroeth is probably much better). It has support for +/- 12 hours
of timezones, 12- or 24-hour time display (with AM and PM LEDs) and DST for US,
EU or Australia (or off). It can come as a board-only “quick kit” (surface
mount components all done and programmed, through-hole left for you to do), a
“quick kit” with a laser cut wood and acrylic case and plug-in power supply, or
assembled (in the case, with the power supply). It has an SMA jack for an
external antenna (that is not included). 3.3V is supplied for active antennas.
Board-only quick kit will be $59.99, assembled $99.99. I’m just waiting for the
inventory of boards to come in before I activate that store listing. But for
now, there’s the Hackaday project page: h
