/r/electronics
Discussion and news about component-level electronic circuits.
A subreddit dedicated to news, articles and general discussions related to the field of electronic engineering.
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.]

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.
Electronic engineering-related posts that don't fall into any other category.
An electronic engineering-related news article or announcement.
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.
A useful or insightful technical note on component selection, circuit design or testing etc. - something beyond 'stick decoupling caps everywhere'!

Iโm making a USB-C powerd, attiny based IR interpreter
If you have your TV attached to a good, mid 2000 Hi-Fi, probably you have two remotes laying around, or if you are a retro gamer, you probably have to get up from your couch to restart or turn off tour PS2. This device allows you to control all from a single remote
It respond to a received IR code with a previously programmed, corresponding IR command to control a second device. It is fully open source and thereโs a github repository for all the work Iโve done so far

fixed a Bench power supply today
broken transformer, insanely dodgy mains power switch (probably Stolen from a lamp sometime) and a shitty solder Job on a 7805 all added up to the thing ending in the scrap pile. fixing all these things made it work again, have to say is a decent low voltage low current supply.

I thought the STM32 was a series of 32 Bit wide-market microcontrollers?
They are now making 64 bit full Linux capable processors under the โSTM32โ name. I can understand putting the STM32MP1 series under the STM32 brand, but this should just be a new line of chips at this point.

2 second mistake, 30 minute botch ๐
Mirrored a symbol in the schematic for better readability, got a phonecall, forgot to mirror the signals too when I continued. Did this botch so I can continue writing the firmware whilst waiting for the fixed board to arrive. So, how is your "Revision A" going?
