Well, its a matter of opinions I guess. The RPi has one UART which is also
the console port, so so much for that, and 17 IOs in total from the link in
the message below.
On the other hand, the BeagleBone Black has 96 IOs including several UARTs.
I have one of each at the moment, and it seems

All looking good with EFC reconnected.
I will chuck it on time-lab shortly.
Except the output frequency is -0.05Hz out.

The C field adjustment on the Rb should have a range of +/- 0.003 Hz a 10
MHz. It is unlikely that you can pull the Rb 0.05 Hz.
The EFC on the OC-VCXO should have a range of 30 Hz. You should be able to
bump the EFC 0.05 Hz.
All that is based (of course) on already having something that

carefully to see if it's drifting and in which direction. If it's
moving, just leave it alone and see how far it will go. Be sure to

If you want a project, you should be able to get an older Android tablet or
a Chumby 8 for $100 or less and hack it to do what you want. Hard to beat
the price for the hardware you get.

If you are doing this from scratch today, would you go IRIG or would you go

in a house. Both are reasonably noise immune. With RS-485 there's less to do.

If you go with the Pi's I2C port, it's strictly a 3.3 volt port. Some (but not
all) of the display boards are 5V gizmos.
If you go with a WiFi approach, be careful about latency. NTP only understands
symmetric delays. Of course if you are on a cable modem there's noting in the

SNTP probably is ok if you are running against an NTP server hardwired on a
local LAN. Running it through a home modem and out onto the internet likely
isn't going to be as good as a full blown NTP stack. You could quite easily get

The first step is NOT to try and write the final program. Get the picaxe
