    Default PIC Nixie Clock project

    Hey Group,

    I am designing an adapter board to allow a 20 pin pic (like a 16F690 or 16F1828, etc) to take the place of an MSP430 processor. Why?? You might ask.

    Well I bought one of these...Name:  clock.jpg

    from here... https://www.tindie.com/products/RobG...xie-clock-kit/ and want to modify the way it works. Unfortunately, for me, it is controlled by an TI MSP430 processor and coded in C.

    The clock is (I believe) an outstanding value as far as nixie clocks go. ($50 usd) which includes the NIXIE tubes and optional case.
    I have actually purchased 2 additional clocks, 3 total. One for my son to build. Then my daughter liked it so much that I told her if she would put it together then I would get her one for Christmas.

    Though the clock is quite a beautiful piece it is lacking in some features that I wanted.

    Self setting time from NTP time source.
    Able to blank the display during certain hours as the clock is in my bedroom and quite bright at night.
    Able to blank the display when not at home to extend life of the nixie's.
    Able to alternately display indoor/outdoor temperature.
    (Add your own feature here...you are the programmer)

    So I designed this... Name:  PCB.jpg

    Which includes one of these... Name:  ESP01.jpg

    The adapter PCB has a spot for a ds18b20 to provide indoor room temperature.
    There is a couple of extra I/O pins to allow you to remotely recieve outdoor temperature if desired.
    Will be able to get NTP time via the ESP wifi module and auto set the clock and keep accurate time.
    Will have a web interface, also via the ESP, to allow you to choose hours of display on/off and easily change other parameters.
    Includes a PICKIT programming header to allow firmware updates easily.

    And will be coded in our favorite PBP BASIC so it will be easy to customize.
    The little 1.5" x 1.5" board is an adapter that will plug into the socket for the MSP430 and fit nicely inside the case.

    So if you are interested in joining in and having some fun and ending up with a nice little nixie clock... well... stay tuned. Or better yet get your clock on order! (be sure to get the optional case) assuming you want it.

    I am not associated with the maker of the tindie clock kit just a satisfied customer.

    I'd be happy to share my code and you can order your own adapter board from oshpark (3 for $12)

    Here is another link to someones webpage reviewing the clock kit... http://maniacallabs.com/2015/03/11/m...-clock-by-rob/

    I have not yet received the adapter PCB from Oshpark, so at this time it's untested. I'll post back here when I get it and assuming no errors, etc. Here is the link to the adapter board... https://oshpark.com/shared_projects/VGYjILPE

    What do you all think??

    These PIC's are like intricate puzzles just waiting for one to discover their secrets and MASTER their capabilities.

    Default Re: PIC Nixie Clock project

    Hey Group (again),

    I have a pretty decent beta version of the code up and running.
    My clock will now...
    > auto set the time via wifi from the esp module (ntp time source) on initial power up
    and every day at 0500
    > blanks the display between 2200 and 0600
    > cycle through all nixie digits to prevent cathode poisioning (every 15 minutes for 5 sec)
    probably overkill but it looks cool
    > you can choose 12 hr, 24 hr or a mode where the hours alternate between 12/24 hr
    for those who can't read 24 hr time but want to learn
    > can display room temperature (but I haven't actually added this to the code yet)

    here are some pics...

    here is my beta version of the code...
    It runs on an 16F1828 or 16F1829 and with minor mods will run on an 16f690

    picIN = mid(picIN,1,5)
    if picIN == "Time?" then gosub [gettime]
    wait
    '
    [gettime]
    bla = time()
    hh = mid(bla,12,2) 'hour
    mm = mid(bla,15,2) 'min
    ss = mid(bla,18,2) 'sec

    picOUT = hh & mm
    picOUT = picOUT & ss
    serialprint picOUT
    '
    return
    '
    [Exit] 
    end
    this has been fun and a real challenge
    IF anyone would like to build one let me know and I'd be glad to help you out with parts procurement, etc for the little adapter board.

    Default Re: PIC Nixie Clock project

    My latest working version of the code is posted below.
    It incorporates Darrell Taylor's Instant Interrupts modified by Tabsoft in this thread...
    http://www.picbasic.co.uk/forum/showthread.php?t=19910

    It incorporates a check for USA Daylight Saving Time

    I currently have commented out the temperature sensor code as I have not decided how/or if I am going to implement a temperature display.

    enjoy

    I forgot to mention that the new enhanced code that needs to be loaded on the ESP module is located at the bottom of the above posted PIC listing. It is commented out so it doesn't interfere with the PIC code.
    This new ESP code provides more NTP time data to the PIC. It now sends day of week, month and day of month, along with the HH:MM:SS

    The pic code used the date information to determine if daylight saving time needs to be in effect.

    Due to drift in the internal osc in the 16f1828 you may want to check NTP time more than once a day.
    It seems to drift about 2 minutes in 24 hours so checking the time 2-3 times a day (or even once an hour) would insure your clock is more accurate.

    cheers
    dwight

    PS if you decide to build one of these please let me know before you order your boards from oshpark as I would be willing to upload a new board design that incorporates a couple of improvements. The boards work fine as is but I found that I overdesigned it to try and turn off the high voltage to blank the display and it is much easier to do that in software by just not turning on any digits.

    Thanks Ioannis!!

    It really is a good looking clock and nice to look at sitting on the book shelf.
    And the fact that it sets itself and I can modify the code to my hearts content is all the better.

    My wife commented that she missed it while I was developing the code.
    It really is, in my opinion, a good value for the $50 USD including the case.

    Dwight, I took your DST segment from the PIC code and incorporated it into the ESP8266-01. I am running the version 3.0 ESPBASIC on the ESP8266 and it works flawlessly. I have incorporated it into my version of the Nixie Clock build. I made a few and gave the kits to 2 of my kids for Xmas. Attached are the pics and ESP code.

    That's awesome Dave!!

    I am glad you could use the code. It was fun (mental challenge) to figure out how to determine DST.
    Although I did notice that this past Nov my clock did not change to Std Time until the day after it should have (as I recall) I was busy at the time and did not (have not) investigated why. I still need to look into the code and see if I missed something by a day. It did get it right the next day so I did not get too concerned.

    I chose to do all the DST calcs in my PIC code as I am much more familiar with PIC BASIC. But the espBASIC has come a long way since then. I am still running version 1.65 on my esp module so I'll have to update the code to be compatible with the newer 3.xx versions.

    It is amazing how powerful the little esp-01 modules are!!

    Hi, Nice idea to get rid of the chip that you don’t want and replace with your own board
    If the ESP module getting the time, then the DT elapsed timer is really just cycling through the tubes?

    On EEVblog, a YouTube channel if you watch it, Dave is in the middle of a nixie project now I’ve been watching.

    Hi Dave,

    go check out the thread over on espbasic... http://www.esp8266.com/viewtopic.php?f=41&t=11518

    and check out his code... he does a better job (simpler code) of determining DST yes/no for the ESP8266
    Note: the following bit of code is not PICBASIC it's espBASIC

    Code:
    [calculate_DST]
    dow = time("dow")
    day = time("day")
    month = time("month")
    hour = time("hour")
    
    if ((DST = 1) and (dow = "Sun") and (month = "Nov") and (day >= 1) and (day < 8)) then
     DST = 0
     write(DaylightSavings,str(DST))
    endif
    
    if ((DST = 0) and (dow = "Sun") and (month = "Mar") and (day >=8) and (day < 15)) then
     DST = 1
     write(DaylightSavings,str(DST))
    endif
    
    return
    and to others... if you haven't checked out and played with mike's awesome espBASIC you are missing out

    I have complete Nixie clock project, written in Picbasic pro, you can find it on instructables "Mid century modern nixie clock". I've updated it to DS3231, added alarm and some other functions (updated code not yet uploaded to instructables), so if anyone can help with hooking ESP to it, I'd be very glad.

    Hi Curious One,

    WOW! that clock on Instructables is an absolute work of art! I'm jealous.

    So what do you need help with as far as connecting an ESP8266??

    If you look at the beginning of this thread you will find the schematic and code for both the esp module and the PIC.
    (Although today, I would highly recommend you use ANNEX RDS as the language for the esp module so you would need to change my espBASIC code.)
    I'd be happy to help you with that code when you are ready.

    It really is just as simple as setting up a serial comm channel between the PIC and the esp module.

    I'd suggest, if you haven't already, that you join the ANNEX RDS group found here...
    https://sites.google.com/site/annexwifi/home
    where you will find a load of information on the ANNEX operating system. (it is very similar to the older espBASIC but much more advanced and development is very active)

    how can I help?

    Thanks for reply.

    There issues are as follows - I'm not a stellar in programing, all what I know is 80s style BASIC and unfortunately have no time or type of mind to learn C++ or some other things. Regarding the ESPbasic, I downloaded it, but was not able to run even a line of code, because it does nothing in browser.

    Regarding hooking the ESP to picbasic, in my clock code I have routine getting time from DS3231. So if anyone can help with same routine but for ESP, that would be cool. Also, by my understanding, ESP is not just plug and go type thing. I mean, if I even add it to my code, say I gave complete clock to friend, he'll need to connect to ESP wifi, to make it work with his access point, manually assign NNTP server and so on. Right? From my point of understanding, GPS or DCF77 looks maybe more complicated, but much more straightforward and easy to use.

    Well, GPS needs clear sky and DCF77 is not available everywhere. I am in Greece and do not receive it or at least not all hours of a day. Maybe if I relocate to a more open area with big antenna... That is not practical...

    I am very interested in ways to use ESP to PBP projects. Have never used that little modules and am a bit afraid to touch them without a step-by-step tutorial. Especially on uploading new firmware and connecting to router and internet.

    Thanks for the response and the link to the board.

    Just to give you the background, I'm completely new to this, so please forgive the very newbie questions that are bound to come.

    I got the clock from RobG pre-assembled when I was last over in the states about 1.5 years ago, and would certainly class myself as a novice at electronics and I've never touched anything related to espbasic. Saying that, I do come from a software background so am more than happy to give this mod a go

    Having done some research on programming PIC devices, I've been looking at PICKit which I think I'll need to get the chip flashed? In terms of the other components that are required to complete the build, I'd really appreciate if you could list out what they are? I know you included you schematic digram in the original posts, but like I said, I'm very new to this so would appreicate the basics.

    Also, in regards to the wifi chip (ESP01), was there anything that needed to be done to that? I see they come prebuilt, but do they just work?

    Looking forward to getting my head into this some more!

    Thanks in advance

    All that is of course somehow good, but not exactly what is needed for PIC Nixie clock. It's like someone was asking about how to use transistor, but he'd being taught first what is Epitaxy, Czochralski method or Gallium nitride doping. We don't need that.

    All what we need for clock is something like this:

    1. flash this firmware.hex into ESP
    2. Connect it's pin #4 (or whatever), to your PIC port X
    3. Use SERIN X,Y,Z statement to get the current time


    That's all.

    I am afraid it is not that simple. You have to write that firmware.hex and then upload it to the ESP.

    In what IDE you will do this? In Arduino C or Annex Basic?

    If it is going to be #4 or #7 it is up to you. I mean what you did in the previous step.

    The serin is the easy part...

    Hi CuriousOne,
    So to help you get a simple time server up and running on an ESP8266 I have a few questions...

    What are your size constraints?
    Do you have 3.3v available or just 5v?
    If you would be willing to use a larger module like one of these...
    https://www.aliexpress.com/wholesale...=lolin+esp8266.

    my favorite is this one...
    https://www.aliexpress.com/item/3272...archweb201603_

    But it really does not matter too much which module you choose.

    You also note that you have experience with old school BASIC.
    I will tell you it is trivial to flash ANNEX RDS onto one of these modules and then code development is drop dead simple.
    The IDE (Integrated Development Environment) is hosted right on the module.
    You only need a micro USB cable to flash ANNEX and then you simply log onto the webpage of the module and you are in the IDE.

    If you get this far I'd be happy to help you get the few (and I do mean few like <20) lines of code up and running.
    Annex makes it very easy to set your time zone and it handles DST/ST for you.
    You would be able to have the module send you serial time out to one of the pins and have your PIC recieve that time.

    It really is that simple!

    Now there are certainly other ways of doing this (like the arduino environment and C-like code) but this Annex is amazing and very easy!
    Oh yeah... and it is very similar to PIC basic and old school basic from the 80's
    But do not think for a moment it is not powerful.

    It is actively developed and very powerful.

    So do you have any ESP8266 modules on hand??

    If you need the small size of the ESP-01 module then it is just a bit more complex.
    Where the other modules have an onboard USB serial channel for flashing, the ESP-01 does not.
    Therefore you would need an USB-serial cable to flash Annex (or any other OS like Arduino).
    Also the ESP-01 does not have an 5v to 3.3 regulator so you have to feed it with 3.3.
    So if you have a bit more room the larger modules are the way to go.

    Let me know what you have or need.

    Id be more than happy to get on a SKYPE to help you get familiar with how to flash annex or understand the features of the IDE.
    Just drop me a direct message through the forum.

    For the ESP, I bought them all - big, small, nodemcu or whatever are available.
    I even flashed some wifi clock project, but using LED matrix displays and it works fine, but that does not helps me.
    I can get 3.3 or 5 volt or whatever is needed, that is not a problem.
