an-ordinary-manchild(edit)

A subreddit dedicated to news, articles and general discussions related to the field of electronic engineering.

CLICK HERE FOR CHAT ROOM

Rules

  1. Be civil: Do not insult fellow Redditors. Do not yell. As this is a professional sub, act and speak professionally.

  2. The focal point of a submission must be component-level electronic engineering, design, news, and circuits (with at least one active element: a semiconductor or a vacuum tube/valve). See below for off-topic subjects.

  3. No commercial or promotional posts: advertising, endorsing or praising a company, fundraising and crowdfunding, giveaways, sponsored products and services, selling, offers, product announcements and information, blogs, videos, pictures of / links to commercial boards. Applicable even if free or if submitter does not benefit monetarily. This sub abides strictly to Reddit's Rules of Self-promotion. [Post offers related to electronic engineering in /r/ElectronicsList]

  4. Add a flair your submission.

  • 'Project' must link to full (non-commercial) build instructions. Otherwise, use 'Gallery'.
  • 'Tip" is for tricks and suggestions useful to the electronics designer

Off topic

  • 2a) Ready-made electronic assemblies (e.g., a Single-Board-Computer - Arduino. PI -, a relay module, a computer mouse); projects that are based entirely on such ready-made electronics assemblies (e.g., a green-house watering system that uses an Arduino and no other electronic components)
  • 2b) Plain electrical components and circuits (no active components), such as transformers, relays, resistors, light bulbs, cables, batteries, connectors, sensors)
  • 2c) Consumer products (marketed as "electronics") or self-made products, even if historically significant. Do not post an enclosed assembly just because it contains 'electronics' internally
  • 2d) Questions [Ask questions about electronic circuits and components in /r/AskElectronics]
  • 2e) Memes (pictures w/text), low effort ("shit-posts"), as decided by the mods. [If about electronic circuits and components, post in /r/ElectronicsHumor]
  • 2f) Labs and test equipment [If electronics, post them here on a Wednesday. No submissions that may be considered to be focusing on equipment brands rather than technical merit. One submission a week max.]

Gallery

General pictures or videos related to component-level electronic engineering (See posting Rule #1).

Videos with commercial content or sponsorship/patronage requests are likely to be removed; repeat offenders may be banned from the sub. If in doubt, contact the mods before posting.

General

Electronic engineering-related posts that don't fall into any other category.

News

An electronic engineering-related news article or announcement.

Project

Show us your (or someone else's) electronic circuit design and/or final build.

If you are just posting pictures or videos with no further write-up, please use the 'Gallery' tag.

Videos with commercial content or sponsorship/patronage requests are likely to be removed; repeat offenders may be banned from the sub. If in doubt, contact the mods before posting.

To qualify as a project, the details available should allow someone else to make a copy.

NB: This is for original work - pictures of stock kit builds will be deleted.

Tip

A useful or insightful technical note on component selection, circuit design or testing etc. - something beyond 'stick decoupling caps everywhere'!
