For some reason the parcel could have been assigned a new code when crossing the border. It happened once to me on a pack coming from Germany as I recall. You may ask the buyer if he still has the envelope to check for other tracking code stickers. So you may find out where it spent all that time.

[neonixie-l] Russian Nixies in real world use (video)

Hello. I just spotted a Nixie-based numeric indicator used in real-world, filmed probably in 1980's: https://youtu.be/KX9hHqByXzo?t=535 (at 8:55) Audio is in Russian, I've no idea what it is counting nor the tube model, but given the type of control room maybe nobody wanted to move to a more mode

Re: [neonixie-l] Nixie Tube Calculator Clock w/Android Control

Eric that's an excellent work and very inspiring. I wonder how much time you spent on it! I have a desk calculator with VFD to repurpose as a clock. I will keep your result in mind when I will be reverse engineering the circuit, in case I can hook it up in a similar way you did. Not knowing how su

Re: [neonixie-l] Free Gerber Files - Nixie Clock

Hello Michael, thank you for sharing. I wonder if you already know which other nixie models you will design the board for? And one request: would it be possible to include in the zip file a jpg picture of the resulting board? I do hope to design and release my own board for B5092/Z560M and alike,

Re: [neonixie-l] Re: RTC chips that behave nicely with crystals

Hello. (In the cheap Chinese modules) DS1307 are not accurate. In a DIY clock for my own personal use (bedside clock ;) ) I estimated the drift and corrected it in software, daily. That can be done since it runs 24/7. I had also found an algorithm that computes the total drift from the set timestam

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 know

Hello. I am about to test and the do something with a bunch of 5870S tubes, both ITT and Siemens. >From the datasheet I see there are two anode terminals, but there is no indication of a reason. Were they made to simplify wiring? Or to make the anode more stable? Should they always be connected to

Hello. Looks like the footprint was called sk116: have you tried looking for this code instead? Then you might search a library for an equivalent tube (as form factor). It worked with sk207 footprint for me. Paolo Il 27/Dic/2016 23:42, "Hatse Flats" ha scritto: > Hello, > > I am new to this gr

Re: [neonixie-l] KiCad footprint for ZM1130

Hello Hatse, have you found some interesting footprint for KiCad? It turns out that yesterday I installed KiCad and gave it a try. Board size limit of free Eagle was my main reason to try the switch over: given that I've not spent more than 10 hours on Eagle I have not wasted too much (sleep) time

Re: [neonixie-l] 1pps signal for old Nixie Clocks?

Hi. I use the SQW output of Maxim RTC ICs (or clones...) in my clocks. It is 1 Hz/pps but I never measured its jitter: I read the time over the I2C bus periodically. I believe they are related so on the long run you get the same accuracy. And my cheap ds3231 modules are right on spot! My Arduino c

Very interesting Jonathan. Any chance you could share a picture of the little warning sign and its position? I have very few of those Nixies and all tested negative, but my counter is quite insensitive. Thank you! Paolo -- You received this message because you are subscribed to the Google Grou

Hello. According to prpopto.com they were founded in 1989 and produce led displays. Their website search for 640 returns a spare for military applications, seven segment green (led). Easy to find out with a multimeter and will not be damaged in case it is a true panaplex. Have you already tried?
