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.

The Pinouts Book: Pinout functions for 130 commonly used components
Obligatory shameless plug of https://pinout.xyz where I’ve been maintaining an interactive Raspberry Pi SBC pinout for some years, and the newer https://pico.pinout.xyz where I’ve tried to do the same for the Raspberry Pi Pico board. The latter also became a command-line pinout via the Python package “picopins”
I feel- and of course I’m biased- that if anything is worth bringing to the table for device pinouts it’s interactivity and accessibility. The latter, in particular, is lost in static images. I really leaned into this with the Pico Pinout, including everything from visual accessibility accommodations (avoiding low contrast text background colours), to markup for screen readers to the ability to turn off labels and reduce noise. I’m still unsure if I actually achieved my goal, but it’s been fun.

Q: KS0212 4 port relay interface to the Raspberry Pi
There is a great resource to be found at pinout.xyz that details a lot of boards and the pins they actually use.
-
Network and dual WAN monitor
All the LEDs have their negative pins together and go through two 1k resistors in series on their way to ground (any gpio ground pin). Then a short piece of jumper wire goes from the positive lead of each LED to it's GPIO pin number. Don't use the pin order number, use the GPIO number.

Show HN: An accessible, beautiful Raspberry Pi Pico pinout
I wanted to create an accessible alternative to the official Pico pinout image, offering more complete pin details, light/dark modes, screen-readable text, and at least some capacity to focus on the peripherals you’re interested in. It’s a sister site to the now ancient Raspberry Pi pinout (https://pinout.xyz/) which started out life hosted on a Raspberry Pi.

Setting up "Adafruit SHT-30 Mesh-protected Weather-proof Temperature/Humidity Sensor" with Raspberry Pi
GPIO PIN numbers - its a real pain with both board and BCM numbers (see pinout.xyz for details) without having to translate what the libraries use by default!

My Star64 displays nothing on the HDMI-connected screen
The pins are at top right corner here: https://pinout.xyz/ and you just connect TX to RX, RX to TX and GND to GND. On the software side you can use picocom on the builtin serial device. Not sure which though, seems to depend on the software and exact revision of your RPi.
- Ask HN: Most interesting tech you built for just yourself?

Wiring buttons to GPIO pins
You can see all the pins on the pin documented at https://pinout.xyz

Connecting a pico-enabled screen on a PI4?
Use pinout.xyz to see what pins are used for the SPI interface on your Pi.

need help with first time useing
You have mixed up the PIN numbers - the Pi has two sets on numbers (board and BCM) - see here for details

Looking for help with transpiling TypeScript to Golang and Python using LLMs
For a auth product, you probably should go with traditional code generation, not LLMs (re: all the unsolvable problems they have (hallucinations, incomplete code answers). For an auth product, you want something definite and reproducible, or you are asking for trouble.
If you are interested in a flexible code gen framework, I built one that had this very use case in mind. (https://github.com/hofstadter-io/hof)
I'd be happy to think / talk this through with you

Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones?
I recently built a TUI for exploring and developing CUE, JSON, Yaml.
Large inspiration for the overall UX comes from the Bloomberg terminal, where every function is reachable with four letter shortcut from the command box. It was really the command box that I liked. I've also built a sort of "flex" panel component for the layout so you can create as many panels as you like.

Ask HN: Are SQL developers generally familiar with JSON, VSCode and Docker?
Many business analysts use SQL, have for a long time. They are probably not your target audience. With the problem being JAVA specific, you'd likely want to start there
This sounds similar to the goals of my hof tool (https://github.com/hofstadter-io/hof), lift type definitions out of code so they can be defined in one place, then generate the code for all the places. Is that sounding like what you are after?

Show HN: Open SaaS – An open-source alternative to paid boilerplate starters
Having built something similar, the biggest challenge for users is that they have to use a bespoke language, like WASP here. I suspect that it is also your biggest challenge as well.
Mine is built on CUE, which at least has the potential to become a more widely used language. CUE hasn't reached sufficient maturity for broader adoption yet, so I continue to face this same problem.

OpenAI: Prompt Engineering
Here's a big one I needed to get ChatGPT to do something more sophisticated with a JSON object response (predates functions and all that)
https://github.com/hofstadter-io/hof/blob/_dev/flow/chat/pro...
It no longer worked after a model update some time ago, haven't tried recently.
I found codellama to be much better for this and require fewer instructions, an anecdotal validation for smaller, focussed models
-
Ask HN: What's the most compelling AI prompt result you've seen?
I was surprised out how you can define arbitrary grammars using arbitrary formulation and it would follow it. Of course you have to redo the prompt every time there is an update... such a pain

HTTPie Desktop: cross-platform API testing client for humans
CUE is indeed a beautiful language, will get those mind juices flowing for sure!
There is more work to be done on the codec implementation, but if you just want to split yaml/json across files, CUE is a great option
You might also like my project, built on CUE: https://github.com/hofstadter-io/hof We have a TUI where you can explore and work with CUE, JSON, Yaml

Show HN: A tool to Convert JSON schemas into TypeScript classes
You can pretty much make up any pseudo grammar like this one, which is a reduced JSON object that is close to CUE: https://github.com/hofstadter-io/hof/blob/_dev/flow/chat/pro...
No need to be formal or use a standard format

Guidance: A guidance language for controlling large language models
Yea, in particular for this project, they have created a bespoke templating system.
You can get the same thing with Go text/templates by adding chat function(s) as custom a helper: https://github.com/hofstadter-io/hof/blob/_dev/lib/templates...

Textual Web: TUIs for the Web
100% one of the best things about building a TUI is not having the pain of modern web development. I do think there is a way to have a CLI & TUI come from the same code, so you can get the best of both, or pick the best for the task at hand.
experiments in progress here: https://github.com/hofstadter-io/hof/tree/_dev/lib/tui
