nwts has a lot of potential to be more than a simple GPS emulator just to set the time from UTC.
There were several requests from customers to extend nwts' functionality.
Last week we released nwts version 2.1 beta. This version includes:
Some customers requested the "Clock drift correction" option:
Two clocks from my customer Jeff Walton: on top there's a Nocrotec Bluedream and on the bottom a PV Electronics clock. The Bluedream clock has a constant delay of -3 seconds, so when connecting the clocks to the same time source, there's always a noticeable 3 delay on the Nocrotec displayed time.
Changing the drift in nwts on the unit that has the delay, increasing it to 3 seconds, makes the Nocrotec clock align the time with the PV Electronics clock.
Here's Jeff's configuration. You can also see the time zone and DST parameters.
The release version of nwts 2, version 2.2 will be available on Sunday, April 2nd 2017. All new nwts units ordered after this date will include version 2.2.
I'm very happy I can add another "non-nixie" clock to the list of supported clocks. All of this thanks to both Chuck and Bob!
When we started in the beginning of December 2016, we would never expect to sell over 30 units in less than one month.
Currently we're out of parts. We're waiting for some - we tried a new supplier - and it's taking more time than we antecipated. The holiday season doesn't help too! We were not worried... we expected nwts sales to go steady but slowly.
However thanks to Ian's excellent review at Tube Clock Database and word of mouth, we've seen a surge with customers buying sometimes more than one unit.
We have new parts arriving anytime now.
We'll let you know!
Thanks for trusting us!
One of my customers, Bob, approached me if it would be possible to connect nwts to this Jeff Thomas GPSII clock.
I answered that if it supported TTL or RS232 for the signal and NMEA messages, it should work...
Well, not so fast. As Bob noticed, it looked like nothing was happening after plugging nwts to the clock.
Contacting John Miktuk (oldvan.com) who designed the software of the GPSII clock, it was clear that my nwts device was not sending the NMEA string as required by this clock.
A small correction on the code, lot's of hardware work from Bob and now nwts is also syncing a piece of Nixie clock history!
Thanks Bob for the valuable input on nwts!
