[neonixie-l] Anyone using the Supertex HV5523?
I was thinking about using the HV5523 to drive some ZM1040 nixies as these would seem ideal - 32 channels of high voltage drive capability and serial data in. I just wondered if anyone else had used these devices and if so, were there any issues? -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Thanks for the quick reply, Grahame. I will be driving mine from a PIC. I might do a layout which has the PIC on the board, but only populate one of the boards with the PIC. using these devices sure reduces the number of IOs needed.

Nigel, I have used the 5522 without issue. The 5523 appears to be a better device with higher clock frequency and 5V logic. I use the blanking input on the 5522 and a PWM output from the uC for dimming. I have used th 5522 with 5V logic directly and 3V3 logic (from a raspberrypi) via a level shifter. Finally, I've chained 3 together to give 96 HV outputs. I normally use the SPI output rather than bit bang. So, not quite your question answered but I would have no immediate concerns.

Re: [neonixie-l] Anyone used Iteadstudio for PCBs?
I've used them a few times. I think their prices are very good which has really transformed my attitude to getting prototypes made. The only problem is there might be postal delays due to Hong Kong customs. I cuurently have a set of board which they shipped last week, I can let you know when they arrive as an up to the minute report.

Re: [neonixie-l] Re: Using 60Hz line-frequency (US) for your nixie clock
I like to use GPS, DCF, MSF because then I don't have to set the time on the clock, it is very accurate and in clock needs fewer buttons. Disadvantages are: GPS - The clock location needs to be able to see the GPS satellites, although these days the receivers are so sensitive you can often make these work indoors. MSF/DCF - Can be prone to interference from TV/Computer monitors and even the switcher in the clock. These disadvantages can be addressed by having the receiver unit remote from the clock and then a low power wireless connection between them, but that is getting a bit complicated. It does mean, if you have several clocks, you could have one 'server' sending to all the clocks.

Three things moved folk away from that - firstly, many countries have de-linked the mains frequency from accurate time, even long-term (more than a day) - its simply not economic to have a false constraint in the mains frequency which is primarily driven by consumer load. Secondly, mains frequency tends to be either 50 or 60Hz, so designs for use globally have to adjust for that and in some countries, you are lucky to get any frequency at all some of the time! Thirdly, RTC chips are plentiful, very cheap and generally provide battery backup so that in the event of brown or black outs, the clock maintains accuracy - most RTC chips provide a xtal stabilised 1Hz output that makes designing such clocks very simple.

The MAX232 however is a 16 pin device and I am looking for something smaller (8 pins). I only need one Rx and one Tx channel. I am also thinking, maybe I don't need one and just use 0V and 5V levels rather than -5V and +5V, but not sure if that will work. Anybody knows more about that?

Re: [neonixie-l] Question on Russian IN-14 kit
I just use the brute force method of using a 40 pin DIL PIC. Nice and easy. Nigel. - Original Message - From: Dylan Distasio To: neonixie-l@googlegroups.com Sent: Friday, November 25, 2011 3:37 PM Subject: [neonixie-l] Question on Russian IN-14 kit Hi all- I picked up a Russian nixie tube kit on eBay which I just received. It's got 6 IN-14s, each wired to a separate PCB with a 74141 on each board. I'm not sure if anyone on list has built one of these before, but I wondered if anyone has any tips for controlling all 6 digits for a clock without needing to control 4 separate inputs on each 74141 individually. I will have to set 24 different inputs this way to control the clock digits. I realize I will have to wire them up either way, but was hoping there might be a trick to reducing the number of unique input signals I need to manage with a microcontroller of some sort. I am still a beginner with multiplexing. I am familiar with it from the Arduinix and other designs but since each tube has its own chip I'm not sure what the best approach is. I'm still a beginner so I am probably missing something obvious. Thanks, Dylan -- You received this message because you are subscribed to the Google Groups neonixie-l group.

[neonixie-l] ZM1040 driving
I'm finally getting round to building my first nixie clock! I'm using 6 ZM1040 tubes with 74141 direct (non-multiplexed) drivers. I have a high voltage switching reg which I can set to anywhere between 170 and 220V. Is there any merit between running the tubes with a high anode voltage or a lower one with a corresponding lower series resistor? What is the recommended current to maximize the life of the tubes?
