OK, again, I am trying to build my first clock. I am off of work
for a long time, can't walk, and have the materials and time. I
like using logic, as I have no programming experience. I would use
micro controllers if there was a program or firmware available.
Basically, can someone point me in the right direction for a simple
beginners clock?

Hi Shane. If you have any interest in learning about microcontrollers/programming I highly recommend the Arduino. They have a lot of example code which could help you get started.

www.arduino.cc

To make things easy, I would start by playing around with your tubes. Get a high voltage power supply and some 74141 ICs to drive the pins.

I recently posted a blog post that may be of interest to you. I use an Arduino to count 0-9 on my nixie tube (Z573M). It's pretty basic.

On my website you can also see the high voltage power supply I used. It's easy for the novice, as you can use an adapter you already have, like 12V, and it will output a sufficient voltage for your tubes. The power supply can be ordered as a package.



If you do decide to do anything, do not touch anything while the circuit is plugged in. High voltages are dangerous and will hurt you.

Feel free to contact me with any questions/concerns.

Thanks for the suggestion! I have the HVPS, and the 74141 ICs, it's a matter of putting it all together to make it work, that loses me.
Thank you!

Can you suggest a kit to start with? Cost is an issue, as I have limited savings and little income at the moment.
Thanks Shane

Sorry to hear you won't be getting around too well for a while. Hopefully you'll recover quickly. As mentioned, it would be a great time to do some playing with nixies.

Along the lines of a kit and using old-school logic, I might suggest the "TI app note" (Texas Instruments applications notes) clock board from John Taylor.



At $6.95 it is a work of art and IMHO can't be beat. You may have a little 'fun' gathering the old 74LSxx ICs. [To get the very best prices, I sourced them from several suppliers. Of course, you have to consider shipping charges too.]

I haven't built mine yet (too many other things going), but am thinking about installing leads to remotely mounted sockets and maybe even using tubes other than the IN-12.

74LSXX you say? you're not going to believe this, but my father in law gave me an old breadboard kit, with a box full of ICs. There are a lot of part numbers from Motorola, Texas Instruments, and other I don't know, that are part number DM74LS04N, SN74ALS00AN, a few Fairchild 74LS86, and abunch of other odds and ends. I assumed these were junk!
SW 74107-N, SN7400N, 4558CPSN74S861, LM741CN, DM74LS02N, FD-1079-CL, 74LS20, DM74LS86N, SN74ALS00AN. A couple of old, waht look like AMD ICs as well.
Is any of that helpful? Do I have something useful here? I have about 45 or so ICs, all kept in a case.

I will look into that board, it looks great for the price, I would like to used the tubes I have, so I might see if it can be adapted to use the ones I have as well. Thanks for giving me a place to look.!

Some good remarks were made (use of #define for instance).

I have another one:
in the C language, all array adresses are 0 based, so if you declare "unsigned char outNum[6];",
?you should only access outNum[0] through outNum[5], exactly 6 elements and no more.
?
So reading outNum[6] in line 56 and following will return undefined value.
Writing to this area may?break the stack and crash your program.

Hi there, Shane.

I'd go for a kit, that's what I did. It's a great way to get introduced to this great hobby.

Cheers

Marco

That was it Nick. Hah. The reason for that was I never use define and assumed if it was wrong the error would be on that line. Guess not! Thanks a lot!

Hi, could you put your code in a pastebin or something like that so we
can see all the code? It will help a lot instead of guessing whats
happening.

Thanks for the response guys. So here it is on pastebin.



The error in question refers to line 82, and every line following that with the same syntax.

....

I might be missing something blindingly obvious here, but why are you using definitions like:

#define IC1A = RB0

That will expand to "= RB0", which will give you a syntax error.

Surely you should be using

#define IC1A RB0 // Note no "=" sign

RB0 is defined in <htc.h>: static volatile bit RB0 @ (unsigned)&PORTB*8+0;

Hi. While that definition seems a bit odd to me, RB0 it is a pointer
unless that "@" has a very special meaning.

Could you please try with this:

*(IC1A) = bitMe(1, outNum[5]);

cheers

There's a Cathode Corner nixie watch on ebay for a fundraiser. I donated it to a good cause - disease cluster research.

It's at $222 right now - a good deal.

Ends today, Sunday at 6:30 PDT which is 0130 UTC.

I have experience with C and C++, but more recently C++. So I may be mixing things. I just find it really odd that I'm getting a syntax error when I'm simply trying to define a variable. It's not saying data type or conversion or anything but "expression syntax" in the error.

bitMe will accept two char inputs. It will return a bit.

IC1A points to RB0.

RB0 is defined in <htc.h>: static volatile bit RB0 @ (unsigned)&PORTB*8+0;

Figured it could be a long shot, but I was wondering if anyone here has a Jeff Thomas NixiSat Kit that they bought when available and never built it.

I checked with Jeff and they're long gone.

If anyone has one for sale, shoot me a message.

Thanks

I'm not an uber C expert or know anything about MPLAB but aren't arrays pointer?

David

This is my function:
bit bitMe(unsigned char weight, unsigned char number)

I call to it in my program:
IC1B = bitMe(2, outNum[6]);

I'm getting the nonspecific error:
Error [195] C:&#92;Users&#92;Mike&#92;Documents&#92;Progamming&#92;nixieClock.c; 55.1 expression syntax

1 - does bitMe accept 2 arguments as input ?
2 - Are the arguments the same type as the input you are giving above?
3 - isn't it IC1B := bitMe(2, outNum[6]); instead of what you wrote (:= instead of =)
