GRA-AFCH NixieClockShield_NCS318_V1_94_TZ.ino with Time zone and automated summer/winter time with example video

I added the timezone.lib plus arduino-additional code to the open-source code as GRA-AFCH made this for their  IN-18 nixie clock with Arduino Mega : NixieClockShield_NCS318_V1_94_TZ.

This is a first version that works, but it might require some coding to be done, depending on where you live.

And THIS is HOW it works:  The startup sequence is shown in the below video:

If you’re not in Western Europe, changing the timezone will be needed.

If I want to spend some more time on it, I can make it fully automated to work anywhere in the world and make the timezone setting done via the menu buttons, requires only a one time setting upon installation.  Maybe later.

This 1ST version makes the NIXIE clock sync to UTC with the help of a to be connected standard GPS module . This was already in the code. Then, the clock changes to the correct time zone, including automatic shifting for summer- and wintertime! 

In the code, I used the Western Europe timezone- and winter/summertime settings.  Also, an example is given for a US timezone. Others can be derived from the examples that come with the newly added timezone.lib from https://github.com/JChristensen/Timezone

These are the available timezones:

// Australia Eastern Time Zone (Sydney, Melbourne)
TimeChangeRule aEDT = {“AEDT”, First, Sun, Oct, 2, 660}; // UTC + 11 hours
TimeChangeRule aEST = {“AEST”, First, Sun, Apr, 3, 600}; // UTC + 10 hours
Timezone ausET(aEDT, aEST);

// Moscow Standard Time (MSK, does not observe DST)
TimeChangeRule msk = {“MSK”, Last, Sun, Mar, 1, 180};
Timezone tzMSK(msk);

// Central European Time (Frankfurt, Paris)
TimeChangeRule CEST = {“CEST”, Last, Sun, Mar, 2, 120}; // Central European Summer Time
TimeChangeRule CET = {“CET “, Last, Sun, Oct, 3, 60}; // Central European Standard Time
Timezone CE(CEST, CET);

// United Kingdom (London, Belfast)
TimeChangeRule BST = {“BST”, Last, Sun, Mar, 1, 60}; // British Summer Time
TimeChangeRule GMT = {“GMT”, Last, Sun, Oct, 2, 0}; // Standard Time
Timezone UK(BST, GMT);

// UTC
TimeChangeRule utcRule = {“UTC”, Last, Sun, Mar, 1, 0}; // UTC
Timezone UTC(utcRule);

// US Eastern Time Zone (New York, Detroit)
TimeChangeRule usEDT = {“EDT”, Second, Sun, Mar, 2, -240}; // Eastern Daylight Time = UTC – 4 hours
TimeChangeRule usEST = {“EST”, First, Sun, Nov, 2, -300}; // Eastern Standard Time = UTC – 5 hours
Timezone usET(usEDT, usEST);

// US Central Time Zone (Chicago, Houston)
TimeChangeRule usCDT = {“CDT”, Second, Sun, Mar, 2, -300};
TimeChangeRule usCST = {“CST”, First, Sun, Nov, 2, -360};
Timezone usCT(usCDT, usCST);

// US Mountain Time Zone (Denver, Salt Lake City)
TimeChangeRule usMDT = {“MDT”, Second, Sun, Mar, 2, -360};
TimeChangeRule usMST = {“MST”, First, Sun, Nov, 2, -420};
Timezone usMT(usMDT, usMST);

// Arizona is US Mountain Time Zone but does not use DST
Timezone usAZ(usMST);

// US Pacific Time Zone (Las Vegas, Los Angeles)
TimeChangeRule usPDT = {“PDT”, Second, Sun, Mar, 2, -420};
TimeChangeRule usPST = {“PST”, First, Sun, Nov, 2, -480};
Timezone usPT(usPDT, usPST);

Be aware,the way I did this is a Q&D method since i have just hacked  this into an existing piece of code, and only do a rewrite of the RTC’s original time after every sync to GPS with the new timezone and winter/summer time rules, so RTC will then become the new local time, either summer- or wintertime.

Since the time and applying the rules of timezone+ winter/summertime is continuously refreshed, not just the time is very stable, but also the changes between winter- and summertime and vice versa are automated.

The required arduino libraries are on the GRA-AFCH Github pagine:

https://github.com/afch/NixieClock

OR-just download the zipped Libraries from our website.

It works really well, please see the zipped file here or copy/paste the arduino code below (you will need some additional files than can only be retreived from the zip-file below, though).

Xmas star door/ window hanger Arduino nano and WS2812 LEDS with LDR

The latest arduino code WITH LDR is HERE:

The LDR is to be soldered between A0 and GND.

The data output is D5 and this must be connected to Data-in of the WS2812 (B) string.  5V and GND goes to the power source, which is also connected to the Arduino Nano.

The STL file for the star parts is HERE.  Print this x5 in semi-transparant white.

The small Xmas- star measures 50cm in diameter from left- tip to right-tip. I printed it with glow in the dark ABS, white.  It glows in very faint green, it is just enough to glow a little and keeps your eyes focused on the star when it is not lit.

If you make the star legs watertight with silicon sealant, the star can easily be attached to an outside wall, door or fence.

ou can use a long 3-wire cable between the Nano and the Xmas star to keep the electronics mounted inside the house and the star outside, or as I did: hang the star inside, in front of any window.  I have the star hanging in my front door window, which gives amazing effect due to the non-transparant glass.

The programming can be altered to make the light effects behaviour any way you like.  I usually have a non-stroboscopic fluent scene running.

You need to print 5 star points, feed the LEDs through them and then have the wires come out somewhere.  You can glue the points together with hotglue or transparent silicone sealant after assembly and testing.

If you don’t have the Arduino IDE yet, download the app from the Microsoft website (Arduino IDE) nor from the Arduino cummunity forum.

Make sure you download my Arduino code and open it with the Arduino IDE APP. Probably the APP will have to move the arduino INO file to a new directory but that should do the trick. If not, start the Arduino app, open my code in notepad and copy/paste it as fully new code into Arduino:  Replace the example code that automatically opens when you open the Arduino program/app with my code.  Save it and rum it to see wether you need to add any library.  For adding libraries, find general help in the Arduino forum.  In my code, you can find the names of the required libraries.

undefined

In the Arduino IDE select the right microprocessor (Arduino Nano).  Then select the correct processor version (large or small memory) and the old or new bootloader.  These choices depend on the type of Nano you bought or still had lying around.  Then you choose the right port (USB) for your Nano.

To test if you have connection between IDE and Nano , you can ask if the Arduino IDE can read your Nano.  Only then you can start loading the Nano with the complicated program.

The BIG 70cm width 5-pointed star with thin hollow legs to put the WS2812 LED string through. AND an integrated tube to put the wiring through

 

The Arduino programming file is HERE.

The latest arduino code WITH LDR is HERE:

The STL file for the big star is HERE.

Afterthougts: I also made circular designs, dual oval crossing designs and a lot of designs that I tied to existing shapes like a steel star, some Xmas animals and so on.  The light design I made varies per application,  A star typically requires a specific design due to its shape.  A cicular design needs more of a scattered design and a straight string or a balcony-wrapped design all require specific patterns of LED programs.

I will also try to implement an auto-scanner in the setup part of the code to identify the number of LEDS that is used, since this is required to get good petterns to the string used.  (set NUMPIXELS automatically)

Circular clock WS2812 & Arduino nano

LEES DIT ARTIKEL IN HET NEDERLANDS

In the above video you see all required parts for the elctronics.  An arduino Nano, a time module LS3231 with battery back-up and a 4-parts ring each with 15 WS2812 LED’s that provide a 160mm 60 LED units clock.  You can build it as an open built unit as shown above with wire strings or in a 3d printable slim case that I developed.  See the pictures below.

For building this nice precise clock, you can use my design files for the housing on any 3d printer that has a horizontal bed size of at least 165x165mm.

Grab both the print STL’s . HERE. from the Prusa shared site where I uploaded these designs. (If the link breaks, search on the prusa site for ws2812 circular arduino clock).

OR get the STL file for the clock’s FRONT from my website HERE

AND get the STL file for the clock’s REAR from my website HERE

One STL is for the rear and includes the Nano box, the other is for the front face of the clock.  Position the rear STL 180 degrees (so up goes down) in your slicer, so both the box and the LED housing are at Z-0 level, i.e. facing down at the same horizontal level.   The front can best be printed with the flat side down.  ABS is not recommended since it has less stiffness, but will probably also work.  For me PETG or PLA works best.

Use white filament for the front part, the rear can be any color you like.

In the circle the 4 WS2812 LED segments are positioned in 1 full circle of about 160mm.

Once you have the rear electronics connected, the front will slide snug over it. No glue required.  But the LED ring can best be glued in 4 places with a drop of hotglue to the base of the rear housing.  Best to do this after you are sure everything works OK.

The LED parts are available on a.o. banggood , aliexpress and so on, search for 60LED circle WS2812 that has the 160 mm outer diameter.

Each LED represents a dot either for seconds, minutes or as hour indicator.

The colors detemine the function.  Blue is also used as Quarter indicator with less intensity, to have a feeling of positioning for the other LEDS when it is dark.

Please look at the video above of the ‘open’ demo model to understand how it works.

Below you can find the Arduino code for the used Nano3, as-is.  it works for me, and in the code you will also find all required electrical connections and the used Time module’s spec.

When connected to your PC, you can program the Arduino and via the serial interface you can afterwards change special settings of the clock like brightness, special quarter dimlit indicators, et cetera.  it’s all in the code below.

The controls can be sent via a serial interface with the usb input of the Arduino, via a terminalprogram like YAT or with the Arduino IDE program’s interface.

The commands are:

  • f; fader OFF
  • F; fader ON
  • m (number); dim the 4 blue marker LED’s with value (number)
  • S; sync to RTC time
  • s; sync to System time (computer)
  • t (time); change system time to:
  • b; brightness of all non-marker LEDs

Please donate $1 to my paypal account if you use (parts of) my developed materials so I can continue to share nice stuff for you to download

Hope you will have a good build!

Cheers,

jan

The Arduino code, to be used for programming the Arduino Nano3 is available at the bottom of this post as plain text to be imported in an empty arduino file (with copy and paste).

Take care to use only the libraries and time module that are specified in the code!  The used time module is of the better generation that holds the time very well, also on standby.

When connecting the wires between the neopixel segments, the arduino and the time module, use a temperature-regulated soldering tool.  Use a fan when you are soldering and don’t inhale the toxic gases while soldering.

The Arduino code is shown below, to be imported in Arduino in an .ino file.  With Arduino, you must compile the code to get the Arduino flashed with the program.  If you want to do this easier, you can make use of the binary file I already compiled for both Arduino nano versions (with full memory and with half memory). Both Arduino nano types will be OK to use for this build, but they each require specific firmware.

The last part of this post is the Arduino program for the clock:

OCTOWS2811, Teensy 1.4 & JINX 64×32 LED display

Using an octoWS2811 is the easiest way to make a LED display as shown above.

For this to work properly you will first need to flash a Teensy module with the correct ARDUINO program and .firmware from HERE:

Arduino IDE – Microsoft Store-toepassingen

Install Arduino including the Teensy libraries and then download the firmware (program file for Arduino, this is an example for 8 straight tubes with 32 x WS2812 ) HERE:

Glediatorteensy64x32matrix_with8x32x8

Then connect the Teensy to your PC, check that Ardiuno recognises rthe Teensy and run the driver program to make the Teensy work as WS2812  LCD driver board.

Then, uncouple the Teensy and plug the teensy into the OCTOWS2811 connector module.

In the RJ45 sockets of the OCTOWS2811 module, plug 2 LAN cables and connect the other end to the WS2812 LED modules.

The maximum number of connections to the LED matrices or DIY strings of WS2812’s is 2×4=8 (Octo).

Then, download JINX HERE: jinx

Run JINX directly  (as jinx.exe , no install needed) after you have decompressed the files.

Connect the Teensy with the USB port to your PC/Laptop.

Power your LED matrices to a beefy 5V PSU.

Check yor wiring.

Define your WS2812  setup in JINX (size X*Y, type of direction, zigzag or other, etcetera) so the output will be pre-formatted correctly for your setup.

Start any output and test it.

If not OK, redefine our preformatted setting of the matrix/tubes setup.

 

CNC pendant for Duet2wifi and Indymill

On the Duet support site a very good description and software for rebuilding a Chinese CNC-pendant for the Duet2wifi is available.

I used this description to program an arduino pro micro, and connect it to the pendant wired, place it inside the pendant and connected the pendant with 4 wires to the Duet.  This works very well.

In the process, I developed some schematics that may be useful to you, available in this post:

Needed: an arduino pro micro and a pendant like this:

China Universal 5V 100PPR CNC 4 Axis Mpg Pendant Handwheel and Emergency Stop F/ Siemens - China CNC Handwheel, Mpg Handwheel

 

In the above picture, the coloured wires on the inside of the CNC pendant are shown. These wires need to be soldered to the correct pins of the Arduino pro micro (at the right)

One of the 2nd floor bedrooms was converted into my 3.5×2  meters mini in-house workshop… The garage is used for my larger machines like the lathes, milling- and welding machines, laser cutter et cetera…

Arduino led bar demo & sketch for 64×16 Canton electronics LED matrix

Module No.:  TB275

//#include <AT24Cxx.h>//no lib needed since we will only use basic functions in 1 page at first

// Author: Phil Kaziewicz 19th July 2014,
// Jan Griffioen did quite some ADDITIONS july-nov 2014 such as RTC, temp, humidity, barmetric pressure, stringtext in time, funny roll-ups etc and voidstructuring
// 64×16 LED display matrix test code
// based upon original code from canton-electonics
// Arduino 1.0.6 NANO V4.0 (with the 2008 Windows drivers; these work with W8.1;

// add buttons or wire bridges for intensity (if possible), speed, language, time up and time down (both last buttons work more agressively when kept pushing…)
// will also try to adapt rotary switches for settings…
// D9& D?? are free for this
// A1 and A3, A6 and higher are free for this, preferrably with a resistor network like on the LCD shields, that should only consume 1 A-pin…
// Add a device for proximity and connect to a ‘button’ input for something like speed or intensity// crash,…
// The development is done with a Nano, after all is OK the pro mini will be glued to the rear of the board and one time programmed via a USB to TTL converter.
// Re-programming only on request!

#include <dht.h>

// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain

#define DHTPIN 16 // what pin we’re connected to; A2=D16

// Uncomment whatever type you’re using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302)
//#define DHTTYPE DHT21 // DHT 21 (AM2301)

// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V! with shield 5V is OK
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor

// Initialize DHT sensor for normal 16mhz Arduino
DHT dht(DHTPIN, DHTTYPE, 10);
// NOTE: For working with a faster chip, like an Arduino Due or Teensy, you
// might need to increase the threshold for cycle counts considered a 1 or 0.
// You can do this by passing a 3rd parameter for this threshold. It’s a bit
// of fiddling to find the right value, but in general the faster the CPU the
// higher the value. The default for a 16mhz AVR is a value of 6. For an
// Arduino Due that runs at 84mhz a value of 30 works.
// Example to initialize DHT sensor for Arduino Due:
//DHT dht(DHTPIN, DHTTYPE, 30);

void switches()
/* the intent here is to use a couple of hardware switches to set all parameters of the system, so you don’t need to update it with the PC.
The systems becomes independent in this way and possibly it can be a sellable item then.

There will be 3 switches: Select , Up and Down. If there is enough room, I will connect them all three to available inputs:
A1= Select,
D9= Up and
D7= Down

The structure is for Select to halt the running programs through the interrupt that is built in the wait void!
Once you are in the switches void the structure is to g through setup with Up and Down, choose the appropriate setting ans Select is, after which you
can again select a new option if available and so on.

I will try to make a function that allows you to press Up and Down at the same time to return immediately or to use is as a reset possibility…

Up and down could also be used as up/down time/date/others by pressing where long press fastens the speed of change…
