Okay, count me in for a board.  Good luck with the training!  Seems we're 
into the same things just in different order.  I'm working on learning 
microcontroller programming and PCB design.

Mahdi,

I am interested in getting one of your ZM1350 8-digit clocks.  I have ten
or so ZM1350s.  I especially like the idea of hosting a message on your web
site (I do not have one...yet) that I can modify by submitting text to.

Re: [neonixie-l] Re: B7971 DUSTOFF Board Interest

Yes that’s certainly possible but are you sure you would like that? There
are more than 100 individual discrete transistors on the board, an equal
number of individual pin sockets, and nearly double that number of SMD
resistors.

Perhaps you really like soldering!

 Yes, all of what you are requesting can be done seamlessly, though it
 requires a wifi network that you can connect to, to be available. Shouldn’t
 be a problem if you live at an airport!

 I have one other interested individual, but need one more in order to
 make putting another batch in worthwhile (the $300 cost is near production
 cost, so it’s a loss if I can’t sell at least of four of five). I will let
 you know if that happens by email

 Thanks!

 These new boards are outfitted with the improved ESP32s instead of

 The cost would be $300 + shipping.

 Thank you.

 The current code for TAF/METAR is attached for reference. If purchased, I
 will adjust the code slightly, to support the ESP32 on the new boards.

Re: [neonixie-l] New clock project with R|Z568M nixies

[newxito]

I found some 2.7k and 1.2k resistors. I tried with 2.7k, still got some 
erros but with 1.2k on the 5V side it works like a charm. I'm using the 
2.5m cable, 2 sockets attached, HV enabled and sending 50 commands per 
second in fast mode. I'm sure that's good enough. All the heavy tasks like 
nixie dimming, slot machine effect and led color cycling will be done by 
the socket, so I don't expect performance problems on the I2C bus.
I found a TI note, they recommend 1.5k for 5V, so that's pretty close.  
Thanks again!

Re: [neonixie-l] Re: B7971 DUSTOFF Board Interest

[Mahdi Al Husseini]

Hi, Peter, very cool! I have my commercial and instrument ratings in rotary
aircraft (and am working on my commercial multi engine FW). Possibly ATP
one day - we’ll see!

Yes, all of what you are requesting can be done seamlessly, though it
requires a wifi network that you can connect to, to be available. Shouldn’t
be a problem if you live at an airport!

I have one other interested individual, but need one more in order to make
putting another batch in worthwhile (the $300 cost is near production cost,
so it’s a loss if I can’t sell at least of four of five). I will let you
know if that happens by email

Thanks!

 These new boards are outfitted with the improved ESP32s instead of

 The cost would be $300 + shipping.

Re: [neonixie-l] New clock project with R|Z568M nixies

A quick test you can do is lowering the values of your pull-ups. You can 
easily use half your current values, assuming you've only placed a single 
one on each of the lines. Should even be able to go lower than that. A 1k 
resistor will result in 5mA at the 5V side, which should be manageable by 
most devices. I'd probably start with 2.2k though and see if that gets you 
anywhere. If it doesn't work with 1k or a new HV supply, you'll probably 
have to take on the daunting task of rewiring the whole thing with twisted 
and/or shielded cables as suggested by others.

Re: [neonixie-l] New clock project with R|Z568M nixies

[newxito]

Thank you all!

I think, daisy chaining is almost impossible because there is no real 
access to the horizontal tube. Maybe it works using a slim flexible cable 
and some steel U-form wires and then trying to pull out the cable trough 
the short vertical tubes. But if I use a separate cable for the HV, I will 
end up with 4 cables in each short vertical tube, I think that’s not 
possible. 

What I did is kind of a star wiring. First, I pushed a cable all the way up 
inside the long vertical tube and it came out on the left side of the 
horizontal tube. Then I introduced a new cable into the horizontal tube 
from the left to the right. After that, I was still able to push 8 cables 
from the top of the short vertical tubes to the sides of the horizontal 
tube, 4 to the left, 4 to the right. Finally, I had to join all the cables 
on both sides. I tested the connections, they are all ok but it does not 
work as expected. 

For the socket I’m using an atmel 328p at 5V and on the controller a ESP32 
at 3.3V. The level shifter sits on the cotroller board under the base of 
the "lamp". I use 2 small MOSFETs. The pull-up resistor values are 3.9k on 
the 3.3V side and 4.7k on the 5V side. The HV supply is a flyback design 
with a LT3757, it works great but I don’t know how noisy this thing is. I 
will try using another HV source.

Re: [neonixie-l] New clock project with R|Z568M nixies

[Christian Riise Wagner]

What value resistors are you using for the pull-ups on the I2C bus? Also, 
what voltage are the microcontrollers in the smart sockets run at? If 
they're 5V, you'll have more EMI susceptibility on the bus, as the ESP32 
runs the bus at 3.3V. A level shifter close to the ESP32 should provide a 
benefit here, as the HIGH level output then won't be as close to the LOW 
input threshold of the smart socket's microcontroller.

Also, it may be that your HV supply is overly noisy. Have you put a scope 
on the output?
