I would be interested in a PCB and a copy of the software ( what chip are you 
using here?) . Please let me know via PM ( [email protected]) how to get the 
specialised pieces and / or circuit and / or overlay and other stuff.


How do you make the NEON towers - can you explain that a bit?

I am a great fan of using GPS - for the following reasons:
1.The clock can self set it self - even if the power is pulled - it will 
re-find the correct time. 'Very new meets old'.
2. The accuracy is Stratum 1 - and can be resynchronised every 1 second
3. GPS modules are low cost - especially serial ones like the Motorola encore 
which also gives a 1pps output as well.
4. Offsets are easy to use and program from UTC  - could even deal with half 
hour offsets
5. Totally global - no issue with things like rugby or other such radio types. 
Good for US or European or Asian.


To this end, I am using some Smart sockets and have just started to build up 
the hardware nad will start the software as well to do a 6 digit nixie clock. 
GPS driven.

Subject: [neonixie-l] 6 Digit Direct-Drive B7971 clock kit

To all,

As some of you may know, Carl Ott of this forum has done a wonderful 6 digit 
direct-drive clock design for the B7971. I have been working with Carl and 
another forum member and have had a batch of PCB's made per his gerber files. 
This has resulted in my building an open-top version of his clock using Carl's 
software which can be seen here on my site:  
http://www.badnixie.com/The_%22Modular%22_Nixie.html  and also on Brian 
Stuckey's site: (scroll down a bit) 
http://www.tubeclockdb.com/nixie-clocks.html  We have received some inquiries 
about offering a kit like the clock you see here. It would be complete with the 
acrylic top, drilled and tapped base plate, colon towers and the whole nine 
yards. So, we're trying to determine if there is enough interest to make an 
initial run of 10 kits. We are not sure of the selling price yet, but our 
driving force here is to offer a product to the community that fills a void, 
not try to gouge our brethren.

Note the aluminum fab'd bracket mounting the rotary encoder. This will be 
replaced with a right angle rotary that will mount directly to the PCB. Carl 
plans to do a little more tweaking to the software as well.
Also there is a fair amount of SMD component soldering involved by the user and 
the kit will be offered without tubes.

Here is a list of the feature set as it stands now.

==Unique Rotary Encoder User interface

==Auto Display dimming feature via photo sensor

==Adjustable DIM and Brightness levels with Adjustable Dimming threshold

==QuickTime Set feature- quickly and easily set current time without entering 
config. mode

==9 Selectable FONTS

==Clock spells out the Month and Day of the week, also displays date and year

==Four user selectable colon modes- OFF, ON, BLINK, ALT, or RAILRD
(railroad)

== TCXO time based

==Time On/Time Off sleep setting

==Smooth Digit Cross Fade feature with fade rate adjust.

==12/24 hour display mode selection

==Leading Zero Suppression selection

==Adjustable Pulse width Modulation setting value.

==Light Value Test Feature to determine optimal dimming point

==CW/CCW Rotary encoder direction selection

Your feedback is appreciated!
