MMM-PenPlotter -Render mesmerizing line animations on your mirror!

Description:

Render mesmerizing line animations on your mirror!

I wanted the mirror to act like a piece of art when I wasn’t using it for Weather, Spotify, Google Calendar etc… The less busy mirror with just the PenPlotting module running creates a really peaceful display. Looks great in the room, and it certainly captures the attention of guests.

Will this work in any valid position and with MMM-Pages, using classes? I attempted to add the module to page 2 of my MM setup, but nothing is displaying, and no errors in dev console. Here is my config:

 {
                    module: 'MMM-PenPlotter',
                    disabled: false,
                    position: 'top_left',
                    classes: 'page_2',
                    config: {
                            imagePaths: ['modules/MMM-PenPlotter/example_svg']
                    }
 },

@BerkSmash1984 what is the pages config?

do other modules appear on page_2?

if u disable pages, does the content appear?

BerkSmash1984

@sdetweil Thanks for the response

Yes, all other modules appear fine on page 2. Here is my pages config:

  {
                    module: 'MMM-pages',
                     disabled: false,
                    config: {
                            modules:
                                    [[ "page_1",], ["page_2"]],
                            // fixed: [ "clock", "MMM-Wallpaper", "MMM-page-indicator" ],
                            rotationTime: 30000,
                    }
},

I did confirm that after disabling MMM-Pages, it does work

@BerkSmash1984 the module delay time is 65 seconds and u have 30 seconds for pages.

so the module is waiting, and then gets hidden, restarting on show. then hidden…

BerkSmash1984

@sdetweil Thanks! Yup I just realized that too and changed the value for MMM-Pages to 6500 and it works. Only thing now is, if you have a background (I am using MMM-Wallpaper to display random in images from Bing and Chromecast) you will see an outline of the whole image instead of what is being drawn.

Wonder if there is a way to address that, besides disabling the background wallpaper…

sdetweil

@BerkSmash1984 welcome to the fun of backgrounds!

somehow you would need to make the image background not transparent, but you will get a big black box instead

BerkSmash1984

@sdetweil lol Indeed! Still a cool module. I will likely go back and forth between this and MMM-Wallpapers… Thanks for your help Sam

@BerkSmash1984
I use both MMM-PenPlotter and MMM-Wallpaper (the jupadin version) and was able to make the images transparent with no black box. You need to edit each of the svg files in the example_svg folder.

Most of the files were updated by adding

fill="transparent"

in the section with:

<desc>pwidth:500;pheight:500;</desc>
    <path
       stroke="#999999"
       stroke-width="0.2mm"
       fill="transparent"

There were a couple where background was already defined in the 3rd row of the files so it had to be updated there. Let me know if you need more specifics.

BerkSmash1984

Oh awesome! I am just now seeing this. Let me give it a go!

@tdw
That did indeed work. Many thanks!

@bballboy21
I am interested in attempting to create one, but how do you handle the code when path is formatted as shown below, with spaces and new lines and not having separate paths individually spelled out like what is discsussed in: https://youtu.be/Nz0SzKKdd-A

The code from this screenshot is the bunny, found at: https://drawingbots.net/knowledge/tools/svg-generator

@bballboy21
Also, if you use https://sandify.org/ to generate a svg file, how do you figure out the number of paths to update the stroke-dasharray and stroke-dashoffset values in the style section, as the svg file will not have individual paths specified?

Example:

If I move the svg file to the example_svg folder on my MM, it just shows to completed picture, and does not actually draw it. I am guessing this is bc the value for both are currently set to 1 (but again not sure how to determine what those values would actually be)

BerkSmash1984

@bballboy21
Disregard, I figured it out. I did not realize that the path is effectively a value of 1 if not otherwise specified, thus following the guide on https://jbamford.github.io/Animate-SVG-Files-Breakdown/ and specifying

pathLength="1"

and

stroke-dasharray: 1;
stroke-dashoffset: 1;

in there respective places in the svg files allows the animation to work.

I can now create as many animated svg files for this module as I like, using https://sandify.org. Awesome!
