I'd like to get tips about electronics projects with the theme of Christmas. Is this question on or off topic?
For Chiphacker, it was definitely on topic. We had a large number of opinionated questions, skim https://electronics.stackexchange.com/search?q=best+kit for a sampling. However, as I understand it, the Trilogy sites are much less tolerant of these kinds of questions, so we may have to adjust our policies a little.
What do people from the Trilogy sites think: Should the linked questions be discouraged?
EDIT: Also, you didn't ask a question. You proposed a subject. For example,
What are some good projects to give to beginners?
Question same as title.
Will be (rightly) poorly received, while one that is asked well, with good details, an example solution, and ideas for a start on the answer will be well received.
Perhaps you can give an example of the question you would ask about a project for Christmas?
As a Chiphacker user who has suddenly found himself a user of the Electronics and Robotics Stack Exchange site without so much as a by your leave, I vote we continue with our existing standards from Chiphacker until someone tells us we can't. Are we not a major section of the user base of this site after all?
I'm not sure how that could be considered off-topic. It's part of "robotics, electronics, physical computing, and even those working with an Arduino", no?
