/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.
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.

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'!

A few things I have bought in the last couple of years
It came out really nicely - the keyboard is silk screen printed over capacitive touch pads:
It looks even more impressive in person. There are a few more details here, but the actual process of getting the boards made was pretty painless. Just needed to send a PDF with the artwork and some guidelines on where it should be printed.

My first electronics project was an annual clock based on something I saw on kickstarter a while ago. The clock slowly advances ~1-degree a day and you can see the year progressing in a whole different way. Just in the 3 weeks I've been working on it has advanced 20-degrees and it gave me an interesting perspective on what % of my year went by in a very intuitive way,
It was a great learning experience and got help from this community too--thanks! If anyone is looking for a simple project that has a fun deliverable, take a look. I think it'd be perfect for STEM programs starting at middle school.

I am definitely open to feedback for any part--hardware, software, instructions, etc--so please share anything that you think would help get more people to be successful with projects like this!
r/ROMarchive is a subreddit for archiving all types of ROM chips contents to make sure they won't be lost forever.
I'v built a circuit that use PIC mcu and CCD to measure the width of things (tube) without using micro meter. the result is quite good. However there's a little point I'll improve later. just to make it best tools.

Bit of a laugh... Random sh&t post...
Knocked up a quick and dirty UV light to try and cure some Chinese solder mask... (Don't ask lol) Running a LOT of UV LEDs And an LM317 with no heatsink... it's dissipating rather a bit of power... 24v supply 🤣
In fact I expected it to blow up 10 mins ago...
Currently sitting on 135degrees C. I could heat my damn coffee on it...
Yet it's still working... Damn... 😂🤣😂🤣😂🤣

This is an attiny85 based IR interpreter i made, it is completely open source (repo and patreon on first comment). The board works, and quite well actually. Planning to distribute some pre-assembled board after a bit of testing. But now it’s time to design a case!
