[neonixie-l] Re: Troubleshooting a mux'd clock

OK, all of the obvious culprits have been ruled out so now we have to consider weird things. Wish you had a schematic, but it's not mandatory. 1. With your scope, do you see similar on/off times at the base of each NPN 'predriver' ? It should be in the milisecond range. Trying to rule-out the

[neonixie-l] Re: Troubleshooting a mux'd clock

Transistors arrived today --- I swapped in a new PNP and still no dice. Since the tubes have individual anode resistors, I remain at a loss as to what the problem is. Waveforms did not change. On the working tubes, I can see the voltage drop across the anode resistor as the tube lights. No

Juergen uses code developed by Pete of PV Electronics.   Take a look at the clocks on the PV Electronics web site.  Jeff Original message From: Alic Date: 11/15/16 5:41 PM (GMT-06:00) To: neonixie-l Subject: [neonixie-l]

[neonixie-l] Re: There's more!

Maybe the seller bid on his own tubes with a different account to raise the price and got greedy? I never understood how people plan on making money on eBay if they only put 2 pictures... There isn't even one where you see them working! -- You received this message because you are subscribed

[neonixie-l] "Firmware" must-have's / nice to have's

Hi Jonathan, Thanks for sharing! Jürgen's clocks (nixiekits.eu) use scrolling to switch between time and date. I find it a nice feature since it uses the digits in the tubes more evenly in addition to the anti cathode poisoning routine. I like clocks with 2 "dots" for each separator column.

Re: [neonixie-l] "Firmware" must-have's / nice to have's

Andy, I don't know about that. I find it takes less effort to set a clock than it takes to configure a network device. It also takes less effort to ensure that you haven't crete a spambot if it's not connected to the Internet. That said, I do believe in ntp for setting the time on our

Re: [neonixie-l] "Firmware" must-have's / nice to have's

This is not completely a firmware feature but a clock for this day and age should be able to connect to my wifi, and then use ntp for time setting. A challenge to make it easy for the user to set up since you have limited display/input capability, but it could be as simple as allowing the user to

Re: [neonixie-l] "Firmware" must-have's / nice to have's

*Jonathan* - Are you running in an Arduino environment, or is the AT328 essentially standalone ? I'm planning to switch to Arduino for my current/future projects, so this is definitely something I'm interested in. One thing I suggest is a 'scramble table' that allows you to handle arbitrary

Re: [neonixie-l] "Firmware" must-have's / nice to have's

Hello Jonathan. First of all, thank you for sharing your work. While I grew up surrounded by RS232 cables, the serial setup sounds not practical and user friendly. In a couple of my firmwares I hardcoded DST changeovers for 100 years (eats up 100 bytes): you only need to reset the clock at a

Hi I know a lot of people here have assembled kits or build there own clock. For driving nixies there are not too many different ways. Since im more "builder" than "programmer" i want to make a firmware thats really good, and use the same firmware for all my future clock projects, so i don't
