Crossfading was covered a couple of months ago:
Are you designing your own board, or using an existing design ? I recently
finished my 7971 PCB design, but I'm in the 'countdown hold' before I send
out the board for fabrication while I make design tweaks and other
improvements.
Sorry, I dont have any extra tubes. Grthey are getting
I'm interested in purchasing B7971 tubes for a project of mine, if anyone
is willing to sell some, feel free to send me a PM and we'll see if we can
sort something out, thanks!

I use shift-registers to control the individual driver-transistors in
non-multiplexed mode. Then, I tie the shift registers into a serial chain
so it uses only 2 pins on the controller (clock, data). So far I've used
FPGA's for control, but I'm switching to a RasPi for the next project. Some
I have room for a clock with really large tubes... I mean, I'll make room!

cold cathode tube power supply ie for fluorescent cold cathode tubes puts out close to 1000 volts of pulsed current. I would not try it. I have an easy way of making portable 1.5-3 volt battery powered handheld nixie tester which I have used for years but the group thought it was silly.
Well, there is also the LD-738, somewhat of a mythical creature that is
rumored to have been even more of a beast than the CD47. Unfortunately
only a few prototypes were ever made... Jens

Like others have said, I'd make room!! That would be a beast of a clock and
would probably light a room quite nicely...:-)

If you were to go bigger, you'd have to make them slightly bigger than the
CD47, so you could claim the "biggest ever nixie" headline, which would be good
for free publicity!

Hi, OK thank you very much!
With heat problems, I was just thinking of a transistor not being used as a
switch but linearly. For example, with a 50V drop across the transistor for
some milliseconds * maybe 7mA = 350mW. Well that is not too bad over just
milliseconds anyway.
I'll just try
I would find room, trust me.

You worry about building them and we will worry about where to display them! :)

Welcome to the group, Paul.
It's easy to test nixies. You just need a small high-voltage power supply
and a current limiting resistor on the anode.
I use a 47K resistor at 170 volts for most tubes. 5900's are smaller and
should work well at 140V or so. I think the z5900m is a clear version
Yep, I love them.
However, they are vastly more complex & subtle than the simple AVRs and
PICs...
I'm currently working on a project using the MSP430FR5969 in
ultra-low-power mode - a CR2032 will power this thing for 2 years...
Everything, and I mean EVERYTHING, has to be carefully considered
SUPER!!!
Reaffirms my decision to change from Microchip/Atmel to TI.
Way to go TI!

Hi,
I received a shipment of tubes (Z5900M) that I want to fire up (becasue,
you know, I want to see them glow!). I have a cold cathode tube power
supply. Could I use that? DO I need to add a resistor to the anode? Should
I get me a power supply of some sort instead? If so what?
Very naive
Just to add, as of now, TI are no longer charging for any of their
development environments, including all compilers etc. i.e. Full function
license keys for all previous and current versions are now available for
free.
If you have CCS 4, 5 or 6 installed, you can now download a free full
BTW, code for everything is on github: https://github.com/judge2005

Hi
I've been working on a project to add a wifi interface to my NCS314 clock. This
clock is an Arduino shield, so it shouldn't be hard to add that to the arduino
right? I used an Arduino that had rows of holes next to the pins and also had
specific connector patches for interface pins, so it
22 matches
