 @ David - that is an interesting idea - I did that already in another
 design  where I wanted to reduce the workload on an ESP8266 so I used a
 Teensy running a state machine based piece of code to do the heavy lifting
 - the ESP8266 just fed data to the Teensy over a serial connection - I kid
 you not - it works really well - though that is all running a lot slower
 than what I need for this multiplexed display project.
 I am actually hoping to do it all on ESP8266 this time round with a
 couple of 595's driven via SPI transfers and some state-machine based code
 which manages the display.

 The next part of my planning is to gain the understanding of what
 delays are required and where.

 I am broadly assuming that I need to do things in the following order:

 {
 Set the cathodes for the number to be displayed
 Delay before turning on anode
 Set the desired anode on
 Wait for the desired 'anode on' time
 Set the anode off
 Wait for the desired 'anode off ' time
 Increment the current anode number (reset to 0 if we got past the max)
 }

 In this way, the anode on and off times can be set - thus controlling
 fading etc

 My next question is - do I need to wait at all after setting the
 cathodes up and before turning the required anode on?

 For the hardware I was thinking that one of the 595's would connect to
 low sided drivers (MPSA42 etc) to ground the required cathodes whilst the
 other 595 would connect to high sided drivers (MPSA42+MPSA92 etc) to
 connect the desired anode to the HV supply.

 I was then thinking that all anodes and cathodes would connect to
 something like 80V via a suitable resistance - as per the Bally schematic
 for driving multiplexed panaplex displays in pinball machines.

 As detailed here: bally_as2518_15_6digit.pdf (pinitech.com)
 

 Am I anywhere near the right track on any of this?

Looks like something I want to build but am too lazy to hand wire it.

Does anyone want to make us a PCB?

Re: [neonixie-l] What's the best approach for this?

[martin martin]

Update:
Will soon replace caps on the calc. board.  
Here's a pic of the power supply. Caps leaking and diodes were partially 
melted from the failed batteries.
More work to do!

[neonixie-l] Very much off-topic

[martin martin]

You've heard this one before..
While cleaning the garage, I found this. Probably built in the very late 
70s.

Uses three 74154 decoders as counters for a near-simulation of a classic 
roulette game.
The design was to let a large cap discharge to "see" the ball slow down.

Enjoy the 70s madness!

Re: [neonixie-l] Re: Jeff Thomas WWVB clock modification

[martin martin]

Speaking of Atomic clocks... I have two Heathkit GC-1000 "Most Accurate
Clock"  complete with the original manual.
* One of them has some mods too.  I have been unable to get either  one
working.

I can post pics if you guys want!

[neonixie-l] Now it's time for some "real" neon!

[martin martin]

I was helping a friend clean out his garage and this popped in to view.  
How could I leave it there to break or be lost?

If one looks close at the clear glass it really looks great.

[neonixie-l] ID these Sperry planar display...

[martin martin]

I found 7 of these while cleaning a friends garage.  I can't make out the 
part number but they are Sperry neon planar segment displays.  About 1/2" 
tall.

I use the larger Beckman in my 1980s Heathkit.

Any ideas?

 Also the voltage between the cathode and the blanking section should be
 checked (I.e. the voltage across C51) and R65 and R67 should be checked (or
 potentially replaced along with C51 if shotgunning it). The rest of the
 high voltage supply appears to be working.

Re: [neonixie-l] Cathode Corner Scope Clock is nearing production

[martin martin]

Count me in!  I have one other scope clock, but it's not too accurate.
Will look good next to the many Nixie and Numitron clocks..

 Another option is available here as a kit:
 https://threeneurons.wordpress.com/nixie-power-supply/hv-supply-kit/
 The site also publishes full details of the circuit which I have used many
 times with success on my own boards. It's a well established design using a
 part which is relatively ancient but has proven reliable.
 As Paul mentioned, layout of these things is often critical so always
 look at the manufacturers recommendations for the layout of components,
 tracks and copper fills as it can make the difference between a functional
 power supply and something that gets too hot and releases the magic smoke
 from time to time (speaking from my own experience).

 The  HV5622  has open drain outputs, so the cathodes will be left to
 gradually float to whatever value they feel like. They probably won't do
 this fast enough to prevent ghosting and you don't really want them to
 float in a multiplexed clock anyway. I would suggest a push-pull chip for
 the cathodes, like the HV9808.

Re: [neonixie-l] best method for pin cleaning?

[martin martin]

look good. Soon to be enclosed in a hardwood box.

[neonixie-l] Re: Another of my "antique" SP-352 clocks

[martin martin]

Hi have the same 6 digit Heathkit.  I do have the complete schematic if you 
need it.  My issue (not solved yet) is the power transformer runs too hot 
to touch. All my voltages are good and the clock still keeps time - I built 
it back in '77

 Well I found another clock to work on, using SP352 displays It 
 is marked DIGITAL CONCEPTS CORP, EC102 electronic calendar clock.

 It uses 3 SP352's for a 6 digit display. A MOSTEK 5017BA chip to run 
 things. 

 The display doesnt light up, at all. In attempting to check voltages, I 
 cannot find any above about 125 (this seems VERY low for the panaplex 
 displays) I have been told that this is similar to a HEATHKIT GC1092d. 

 Anyone got any ideas, maybe a schematic for this guy?

[neonixie-l] Neon and Mercury

[martin martin]

Greetings all,

These are no longer available in the US as of 40+ years ago. I found one in 
a box and had to put it back in to service!
They were sold as "silent switches".  Small tube of mercury to make the 
contact and the toggle switch has a large NE-2 for a nice looking night 
light.

 Enjoyed watching that, thanks for sharing.
 Any idea what the large round tubes were used for back then?

Those nimo look like tiny CRTs!  If anyone can make them it’s Dalibor!

[martin martin]

Just curious, what's the filament voltage?  27VDC?  And what's the HV?

[neonixie-l] ZM1032 - Dual Anode

[martin martin]

I was building up a two-digit Nixie thermometer with leftover tubes I found 
I a box
To my surprise, the ZM1032 has dual anodes.  Designed for multiplexing.  I 
am using direct drives.

I have two of them if anyone can use em!

Looking great?  Will it be close to "Cathode Corners" rechargeable?  I
think David uses the same Burroughs tubes.  I have a clock or two using
those.  They are clear, bright and last long...

 Recently started up a longtime nixie project I've had in mind. Quite
 ambitious (for me at least), and something that hasn't quite been done
 before to my knowledge. This is a 4 tube, bluetooth enabled (nrf52832 mcu),
 direct drive (not multiplexed) watch with burroughs b5755r nixies that I'm
 currently getting out of my head and onto paper. It will include features
 such as capacitive touch buttons, programmable accelerometer, automatic
 light sensor, removable 14500 lithium battery, and smartphone app for all
 sorts of display effects and options. No LED backlights on this one; its
 all about the neon!

 It's nowhere near complete; the design currently exists in the digital
 domain. I'm closing in on the first "complete" revision in the next few
 weeks. Current dimensions are 59mm square by 28mm deep. Its quite large to
 be hanging off of the wrist.. but are there really any rules when it comes
 to a timepiece as unconventional?

 The software development will also be a tremendous task. Slow and
 steady wins the race here!
