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 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

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.

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! (Sent from phone.) Original message From: Dalibor Farný Date: 21/01/2017 21:08

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

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

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

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
