Even though they have the primer, I found that initially the tubes struck in different places and were irratic when trying to sweep a bar across the tube. I ran them 50% over current for a few hours and then used the controller to continuously sweep them backwards and forwards. After a few days of this treatment they started to behave and have worked faultlessly since. I've no experience with IN9 tubes. If you look at the schematic you will see it is very crude as I do not use any opamps to offset the voltage drop but only run the DAC over a limited range.

Re: [neonixie-l] Re: IN-9 drivers
Funny I immediately dismissed this idea originally because I always think H-driver for DC-to-AC; using 4 switches. For my clock this would have been too costly. I didn't realize that replacing the upper 2 switches with resistors was perfectly fine and resulted in negligible wasted energy. In the case of my big clock, the PCB layout routing was too dense in 2 layers to use 2 resistors per bulb, even using resistor SIPs (though SMT would have been fine). WIth a high-enough DC supply, I could connect bulbs in-series (which saves on resistors). -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] Dalibor's Nixie tube: R|Z568M
Dalibor, You are doing some great work! I know a few of the sort of issues you deal with in putting in so much hard work and lots of your time into these tubes. There is no way to ever charge enough for each tube when you sell them to pay you decently for your time. I run into this same thing with my newly made recording-blank cylinders for use on Edison cylinder phonographs. You are doing for nixie tubes what I've done for brown wax Edison blanks. These blanks are for sale, but that is just for fun, the price is just a token amount. There is no way that I can ever be compensated for the sheer amount of time this has taken. Completely O.T., but here's my website for anyone interested: http://www.richardslaboratories.com Chuck Richards Original Message From: amelyena...@gmail.com To: neonixie-l@googlegroups.com Subject: Re: [neonixie-l] Dalibor's Nixie tube: R|Z568M Date: Sun, 15 Feb 2015 21:00:35 -0800 (PST) Dalibor: Have you considered adding decimal points to your tubes, or perhaps recreating a tube that has decimal points?

Re: [neonixie-l] Re: IN-9 drivers
Let me take a step back - the current schematic is not MCU based, let's say it's analog. The building blocks are: input amp - bandpass filter - lin-to-log converter - AC-to-DC converter - driver The LPF is between the AC-to-DC converter and the driver. At that point, the audio signal has been already filtered, so in theory I should have only the DC component of a specific channel/audio frequency.

Re: [neonixie-l] Re: IN-9 drivers
I can't answer that question from knowledge. Gas filled tubes (being pedantic these indicator tubes are not nixies) are relatively slow devices as ionisation and deionisation are a slow processes. My answer would be that HF noise would be ignored; now someone who does know can knock me down :-) But if you are building a spectrum analyser with the bandpass filters done in a micro, why do you need LPFs? Or have I missed somthing? If you are going to use external filters then you need one per band and they must be band-pass not low pass? On 16/02/2015 18:16, Mihai wrote: Thanks for the tips.

Re: [neonixie-l] Re: IN-9 drivers
AC-to-DC converter LPF driver rectification smoothing DC to driver Are in some way equivalent. So decide on the degree of smoothing required and you are home. But I think we have come full circle back to your LPF requirement I can suggest two ways - build a channel and experiment increasing the amount of smoothing until you get the look right - this is not going to be a precision instrument. Or try modelling the circuit. I use the open-source Qucs as it is free but you have to learn how to use it.
