Support for multiple stencils, operated by servos #78

Open ruedli opened 6 years ago

ruedli commented 6 years ago

My clock has three moveable stencils, that can be moved with servo's.

All is working now, and I have created a plugin to allow for choosing the template to use for time_default, sunrise and matrix_time.

You need to install and enable i2c support and import the ADAfruit_PCA9685 module.

I have:

The code and configuration files contain explanation and examples.

I have tested, that this also works "without" the new hardware for the servo's, so it does not break the functionality for clocks without servos.

I have everything versioned in git, but have trouble committing this delta (I do not see "files" on a branch to commit to), so for now enclose the "unified diff" as pdf.

as well as the modified / moved files.

Please let me know how I can contribute it into the repository, and what to do next. Will try to upload a video as well with this new "feature" all people that have seen it so far, were very impressed... And, obviously the clock pleases me as well. (Perhaps exchange by mail further info, that would be much more efficient)

Thnx Bernd for creating the excellent starting conditions for having this feature!!!! As I implemented these changes, I got very impressed with the nice framework you have created, software and hardware!

And... here is the video....

With some pictures of the mechnism, Software, with a new plugin, is now fully functional, I intend to build a second row of 3 servos to the right, currently I only use 3 servos, one for each stencil.

It all fits in a "swedish furniture store" 50x50 frame. For the video I removed the transparent front. The 3d printed mechanism (own design) is only 20mm thick.

This picture shows the driver for the up to 16 servos, a 2 dollar TDA-9685 breakout. (Uses i2c and does all timing stuff, without bothering the raspberry pi)

Hi @ruedli, really nice clock! Thanks for sharing!!

....definitely a strong candidate for the gallery (...to come...)

Hi Bernd,

As mentioned, I have the code managed under git here on my PC, how do you want to proceed now?

Leave it on my PC only? -or- Review the changes and merge it with your code repository?

I set it up in such a manner, that it does not break the functions for people not having servos to operate the stencils. At the same time, people who swap their stencil manually, with magnets e.g. could benefit from the "stencil changer" plugin.

There are new dependencies however: for i2c and the Adafruit library, they must be included in the software installation doc.

You can mail me to my private mail, to exchange ideas on the merge, also I could program other new feature, I intend a few more addons myself.

cheers Ruud

(ps. I also resolved a "bug" when you configure the initial brightness level at a vaule larger then 247, it crashes the clock in an attempt to set the intensity at values bigger then 255, the "check" for bigger then 255 was at the wrong place, and the "change direction logic not working properly)

Hi @ruedli,

please create a pull request to "develop".

Then we can discuss changes in detail and decide, whether to integrate the soures (and documentation) into develop (preferred!) or leave it on a separate branch.

Best, Bernd

Hi Bernd,

Sorry I feel like an idiot, but despite more then 15 years experience selling configuration management solutions, I do not succeed in uploading the delta's to the files...

When I create the pull request and "drag-and-drop'.py files, I get a file type not supported. I never see a directory tree, where I would expect to be able to upload individual files.

Finally, I did not base my development on "develop", but on the master copy of a week ago. The develop already contains a change. Even if you already migrated it, adding my change there should create either a conflict or undo the intended change currectly in the development branch. (If I understand correctly how this is supposed to work...

So please, a little help on making the pull request work for us, so that I can update and add .py files and that we use the correct baseline for the pull request...

(sorry for not understanding)
