A subreddit for the low-cost software defined radio (SDR) community. While originally dedicated to the [RTL2832U USB rtl-sdr](http://sdr.osmocom.org/trac/wiki/rtl-sdr) project, relevant content related to general SDR, RF, and similar projects are also welcomed.
Welcome to Reddit's own amateur (ham) radio club. If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. All topics relating to the hobby are welcome here, from purchasing and building equipment, to operating techniques and activities, and everything in between.
Subreddit for review / layout / manufacture of Printed Circuit Boards (PCB), including schematic capture, assembly, soldering. Related topics: Altium, Eagle, DipTrace, KiCad, Gerber, PCB, Breadboard, Electronics, Electrical, Engineer, Arduino, Raspberry, STM32, ESP32, AVR, ARM, Embedded, SPICE. Our WIKI is located at https://www.reddit.com/r/PrintedCircuitBoard/wiki/index
A place to ask questions, discuss topics and share projects related to Electrical Engineering.
Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. AskEngineers is a forum for questions about the processes and standards used to build these systems, as well as for questions about the engineering profession and its many disciplines.
This sub is dedicated to discussion and questions about embedded systems: "a controller programmed and controlled by a real-time operating system (RTOS) with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints."
Welcome to the Hardware Startups sub-Reddit - feel free to post on anything that you think will interest anyone in the community. The idea is that we're a blend of r/DIY and r/startups content - like a Hacker News for hardware. Good ideas: hardware news, prototyping/manufacturing how-to, success stories, physical Kickstarter pages, etc. Bad ideas: General startup stuff, DIY articles without a startup angle, TC/VB/etc. link-bait, etc.
The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
