I created a separate user group https://groups.google.com/forum/#!forum/b7971-driver-board-user-group for neonixie members who are interested in building a clock with b7971 tubes using my PC board. As of now, I dont have any more PC boards. I have 2 boards running, but we need to have more

If you want 10msec granularity, traditional Linux may not be the right choice. I did quite a bit of data-gathering (See my April 14 post in this subject), and got 64-bit serial packets to transmit , on average, in 32usec. Occasionally there is an outlier, on the order of milliseconds, due to

Greg, is I/O fast enough to support cross fades? For a really smooth fade, I think updates must be 10ms or less. -- 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

Re: [neonixie-l] Re: Raspberry PI controlled Nixie display

Good news. I had wondered about using a PI myself but was concerned with lack of realtimeness. BTW, in regular UNIX you would set your app up as a demon that runs at boot up. Crontab would not be the way to go. There should be a bunch of stuff in /etc/init.d or /etc/initd or something like

Re: [neonixie-l] Re: Raspberry PI controlled Nixie display

Thought I would post a follow-up regarding a RasPi as a nixie controller. So far, using a RasPi Zero W for controlling my latest nixie clock (8-tube b7971) has far-exceeded my expectations: - No 'helper' FPGA is needed; there is far more than enough horsepower in the Pi to handle all of

Another option for a nixie socket/adapter would be the ones available from our friend Pete over at www.pvelectronics.co.uk. Pete is very active, and I have used his clock kits to build several clocks. I have also purchased the adapters you need to fix some of my horrible soldering jobs. Now

Re: [neonixie-l] Re: Raspberry PI controlled Nixie display

I got my RasPi-based clock to display time last night, so proof-of-concept is done. Right now, I'm using seven b7971 tubes. All of the compute-related stuff is done via a 'C' program running on the RasPi. I had planned on adding an FPGA to offload the RasPi, but so far I have not seen a need

[neonixie-l] Re: Raspberry PI controlled Nixie display

I ran a few more tests on serializing a 64-bit stream using C-language and the wiringPi library. Typically, I'm getting around 32usec (measured on a scope) to send the 64-bit burst, which is decent for software-controlled GPIO's. There are timers available in wiringPi, but I found they are not

[neonixie-l] Re: Raspberry PI controlled Nixie display

I have an FPGA as my 'Plan B', in case the there isn't enough predictability in the Pi to display time down to the second. It wouldn't be much work to modify the Verilog code I did for my previous clock to allow the Pi to handle daylight savings, insert text messages, and possibly correct for

I'm just using C, and so far I have not chosen a development tool. The info I found on sparkfun mentions Geany (and it's included in the current raspian image), so I will try that first. There are sample programs included in the wiringPi distro for I2C and SPI. Have not tried either yet, but

[neonixie-l] Re: Raspberry PI controlled Nixie display

I chose the RasPi zero-W (the newest Pi, for $10 US) because it has built-in WiFi to do periodic time-sync, and it will allow me to update my clock software remotely, rather than taking the clock apart each time to update FPGA code. My concern is the limited GPIO speed of the Pi, so I will

Yeah, but this is costly due to custom transformer used. I'd prefer a 12V supply and cheap NE555 converter or 5V + voltage doublers, as this is just cheaper than those 'ready to use' modules from ebay. On USB you are heavily limited with current anyway, so the clock has to be multiplexed or

I wonder just wondering, if anyone has made a RPi hat that adapts to an Arduino header so that you could use an RPi with any (well, most) Arduino shield as there are 1000's of Arduino shields and only a few 100 (maybe) RPi hats... Just a thought... RATS! Someone else thought of it first -

Unfortunately there aren't any original IN-14 sockets. But there are good news: you can easily buy IN-14 to 2,54mm adapter from OSH park. I don't know if there is any existing project like this, but for me it is really short work and I could make gerber files for such PCB*. OSH makes three
