Hi All --

The production batch of TICCs has arrived at TAPR and the first
shipments to customers are going out today.  It will probably take
another few days to get them all sent -- there are nearly 100 units
going out the door!

As previously mentioned, the TICCs have been loaded with software and
tested, so they should be "plug and play" when they arrive.

I've been working on the user guide, and while it's still a bit rough, I
think it's fairly complete.  You can download it from

https://github.com/TAPR/TICC/tree/master/docs/TAPR%20TICC%20User%20Manual.pdf

The installed software version is "20170108.1" Since then, I've
implemented a couple of new features, including semi-tested code for
slaving multiple TICCs into a 4 or more channel counter (semi-tested
because I still only have one unit!), and a polling capability in
addition to the normal "talker" mode.

The updated source code is available at

https://github.com/TAPR/TICC/tree/master/TICC

If you don't want to install the Arduino IDE and build/upload the code
yourself,

https://github.com/TAPR/TICC/tree/master/binaries

contains a compiled version, as well as a simple Windows tool to upload
it into the Arduino.  The User Manual has instructions on how to do the
upload.

Enjoy!

Another info about the HP5065A.
Some test Cooling the HP5065A from 39.5 to 29.5°C (chassis temperature) show a 2E-13 / °C, positive slope.
The first graph show the frequency drift, the second the temperature drop and the voltage at the A15 pin 2 (magnetic field set point regulator).
I am working on a project to compensate pressure and temperature starting from the Corby Dawson study.
I am planning to made an smd version of the board.
This circuit with some minor change can be applied to any Rubidium standard.
