Greg, Overvoltage is not a problem if at least one cathode is turned on when the anode is turned on. On Tue, Mar 6, 2018, 9:58 AM gregebert wrote: > Interesting. The HV5812 is a CMOS device rated for 80V, so it will be > vulnerable to overstress if the nixie tubes leak (no bleeder resistors are

Re: [neonixie-l] Re: status of original Weisling FLW kit design? Clone kits? Software?

There must be hundreds of that design out there. I personally sold more than 100 kits of one kind or another and the Jeff Thomas version used the same circuit. I've used it with regular nixie tubes as well as B7971s, and I've never heard of one failing. -- You received this message because

Re: [neonixie-l] Re: status of original Weisling FLW kit design? Clone kits? Software?

Sorry, I did miss that. It definitely solves any potential problem with nixie leakage, clamping it to a safe value. Much better solution than tying a bleeder resistor across each segment driver. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] Re: status of original Weisling FLW kit design? Clone kits? Software?

You obviously missed that in my design, pin 1 of the HV5812, the VPP pin, is tied to approximately 60 volts. An "off" output then is pulled up to 60V, which is high enough that the cathode is extinguished, and any leakage current is clamped to 60V. On Tuesday, March 6, 2018 at 8:58:46 AM

I'll bite: The datasheet says the HV is controlled by MOSFETs: "It combines a 20-bit CMOS shift register, data latches and control circuitry with high-voltage MOSFET outputs". On Tuesday, March 6, 2018 at 11:58:46 AM UTC-5, gregebert wrote: > > Interesting. The HV5812 is a CMOS device rated

Re: [neonixie-l] Re: status of original Weisling FLW kit design? Clone kits? Software?

Interesting. The HV5812 is a CMOS device rated for 80V, so it will be vulnerable to overstress if the nixie tubes leak (no bleeder resistors are present). Has anyone ever had driver failure ? If not, then I guess the blanking time is sufficient enough for charge to decay to a safe level, or

Its an HV5812, with cathode resistors and MPSA42/92 anode switching. I guess Pete could give you all the details. On Monday, March 5, 2018 at 5:36:13 PM UTC-5, gregebert wrote: > > What kind of segment driver does the FLW use ? From the PCB layout, I can > see it's a multiplexed display. > --

What kind of segment driver does the FLW use ? From the PCB layout, I can see it's a multiplexed display. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an email to

I havn't added word-capability to the software yet, but that's very easy to do. Obvious things like holidays, birthdays for folks at home, and perhaps phrases for "2 minutes hate". As others finish their clocks, I'm hopeful that software contributions will generate more interest. Right now
