Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Did students lose interest in electronics as a hobby in the early 80s?
We made abstractions successfully, world changing abstractions.
Do the NAND to Tetris course and see that tech is abstractions on top of abstractions. Electronics today is frequently represented by code. Check out Verilog or VHDL.
https://en.wikipedia.org/wiki/Hardware_description_language
Where electronics stayed interesting is in the realm where code meets reality -> robotics and art.
Playing with LED's, robotics competitions, quad copters, cosplay. Maybe adjacent to SDR. Raspberry Pi's and Arduinos.
Check out ADAFruit: https://www.adafruit.com/
or Sparkfun: https://www.sparkfun.com/
Check out sites like: https://hackaday.com/
There is also the greater cultures: Maker culture and hacker culture. Maker Faire is super interesting and has many many attendees.
I would say that in America, it is harder to work with electronics because the number of maker spaces and places you could buy parts (RadioShack/Fry's) greatly diminished, but afluent folks can definitely have an electronics hobby supplied by online vendors.
- A local solderless electronics vendor?

What would be a super cool gift for an electrical engineering student?
It's really a golden age for EEs. If he likes to play/experiment with stuff, then a good online store is Sparkfun. My wife still gets me gift certificates from there & I love it. You can make/create A LOT of things from there. If he likes to program/software, you will find a lot there.

LPT: How to not shop at Amazon
for specialized things, look for specialized sites or services. For example if you're buying spicy Korean ramen on Amazon because you can't find it locally, check to see if a service like Umamicart might deliver in your area. If you're ordering organic groceries from Whole Foods (Amazon), check to see if a service like Thrive Market might work for you. If you're into hobbyist electronics and want to pick up some Arduino gear, maybe check out SparkFun. Each of these companies is run by people who are passionate about the market they've specialized in and they're a better place to spend your money than Amazon.

My 14 year old son wants to learn how to code
The other reason to lean towards C++ is the land of ARduino. Arduino is a microcontroller board where people ( a lot of kids really) create real world projects. It is pretty cool as the hardware can be used to drive model servo's, read form sensors write to displays and offer a lot of fun to a technically inclined child. You can learn about Arduino here: https://www.arduino.cc/. This melds the world of programming with real world hardware and gives a kid plenty of avenues to follow. Some sites that encourage educational exploration with electronics: https://www.adafruit.com/, https://www.allelectronics.com/category/209/educational-kits/1.html, https://www.jameco.com/shop/keyword=Educational-Electronic-Kits, https://www.sparkfun.com/ and likely several hundred more. In any event mixing electronics and programming is a good way to learn both with a meaningful hobby. Robotics can really prime the interests in writing software.

Resources for designing circuit board on embedded systems
Sparkfun sells tons of MCU dev/breakout and sensor boards, and the schematics are available for nearly all of them, along with "hookup guides". Look under the Documents tab for each product. You can learn a lot by studying these.
- Very new to robotics. What type of robot should a beginner like me build first?

I'm a newbie wanting to make a system to measure atmospheric data at intervals and record it in a spreadsheet. How do I get the data from my device to CSV?
Other companies do this as well, like Sparkfun, DFRobot, Wemos/Lolin, etc. I feel that Adafruit goes the extra mile. And that has won my loyalty.

Is this any good for testing vintage audio/radios components? Which one is the best tester if budget is not a problem.
As far as I understand, this is one of dozens of similar clones of the "transistortester" (https://github.com/Mikrocontroller-net/transistortester) originally designed by Markus Frejek, Karl-Heinz Kübbeler and others. They work fairly well to identify most simple components.

What would be a super cool gift for an electrical engineering student?
There could be so many improvements... and there are already so many versions of the original. For example, for old caps, sometimes ESR is so high that it shows up as a resistor... how about an op-amp tester?
- Well this isn't good.

How to know these two Capacitor value.
Buy or build cheap transistor tester.
- I want to hook up this OLED ssd1306 to my Arduino. Does anyone have schematics of how to do this (via SPI)? I want to design my own pcb with the display soldered directly to it, which is why I'm not just buying an off-the-self OLED from eg. Aliexpress.

Is this worth? Hi! Can you tell me some cheap but nice component tester? Thank you.
This is the link to the current wiki article, including the english versions: https://www.mikrocontroller.net/articles/AVR_Transistortester

My friend gave me his OG xbox that wouldn't power on. First time working with power issues. Assuming these 4 rusted capacitors are the culprits, but is the white gunk in the PSU supposed to be there as well?
You can start by recapping the system if you don't mind the cost of a capacitor kit, and don't want to test suspect capacitors. If you do want to check suspect capacitors, you will need to remove them from the circuit, measure across them for shorts, and check their capacitance, and ESR. Multimeters may not have a good range for capacitance and may not tell you ESR. For that, you can use a general component tester--normally listed as a 'transistor tester' online and based off of this open source project.
What are some alternatives?
Adafruit_Sensor - Common sensor library
ATmega-Transistor-Tester - Small version of the famous component tester from mikrocontroller.net
DHTNew - Arduino library for DHT11 and DHT22 with automatic sensor recognition
ESP-Google-Sheet-Client - Arduino Google Sheet REST client library for Arduino
Google-Sheets-Logging - Log data from an ESP8266 device directly to Google Sheets without a third party service. Log sensor data, send data by pressing a button, and receive data from a Google spreadsheet. (NodeMCU, Wemos D1 mini, Adafruit Feather HUZZAH, etc)
Rotary_Encoder_Breakout-Illuminated - This is a clever little breakout board for both the RGB and R/G illuminated rotary encoders.
RF_Links - These wireless transmitters and receivers easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link.
