David,

Thanks for the info and link.  That will be very helpful.

Still would like to have an documentation that Jeff may have provided with 
the clock.  Also trying to figure out how to set the seconds on this thing.

Re: [neonixie-l] NixiChron upgrade, new firmware, NixiChron style case...

2016-10-04 Thread Wayne de Geere III 
I’ve got a handful of Nixisat and Nixichron clocks all of which could use 
modern GPS upgrades. My cylindrical acrylic Nixisat has been down for a few 
years because the original GPS board died, and it’s just been sitting in 
storage.

Is the firmware update from John Miktuk? What is the version?

Re: [neonixie-l] Re: INS-1 flickering

2016-10-04 Thread TheJBW 
Gene,
It is possible, although I somewhat doubt it. The supply source is a 12V 
cheapo amazon 2A unit driving a Tayloredge 1364 module on a Tayloredge 1355 
backplane (along with 6 IN12As). 

The 12V supply is driving several other modules (an IN13 module that I 
built -- which is powered by an independent 1364 taking 12V input), a 
raspberry pi, an amp, and some low current incandescent indicators. While 
these obviously will load the power supply randomly over time, peak draw is 
on the order of 750mA and all of this hardware was installed weeks before 
the flickering began.

In any case, definitely strange and maybe a unique case, but perhaps worth 
using a test rig on any INS-1s that are unstable but might be saved.

[neonixie-l] NixiChron upgrade, new firmware, NixiChron style case...

2016-10-04 Thread Mitch 
Hi All,

Only a few Nixichron upgrades are left. I have three ready to go, and a few 
more boards to be assembled. I may order more toward the end of the year, 
but it won't be an ongoing business, for sure.

A new firmware release is ready. Some minor bugs were squashed, a few 
options were added or changed, and most importantly, better tracking to the 
GPS. I'll email the hex file to anyone who can flash it, or send the board 
back and I'll do it for the cost of return shipping.

Next project is a Nixichron style case. I know a manufacturer that has 
large CNC machines and the owner said it would not be a problem to make the 
cases. We'll see. Talk is cheap, but they've come through before. A sample 
will be ready in a few weeks. If it goes well, I'll make a version of the 
Zev clock for it in both six and eight digit configurations. I won't offer 
kits, 
probably just cases and boards. The MOQ on the cases will be 50-100 pieces. 
Again this will not be an ongoing business, just a one time thing for fun.

Mitch
