Rules

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