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.

Nyan Keys - An FPGA Based Mechanical Keyboard I Engineered for Low Latency - Open Source
Nice - a friend and I worked on my keyboard's debouncer and call it "eager debouncing", not sure if there's an official term for it. I agree that it's much better for latency.

Ask HN: Most interesting tech you built for just yourself?
Awhile ago I made an remote infrared sending tool so a raspberry pi can control my A/C unit
https://blog.bschwind.com/2016/05/29/sending-infrared-comman...
Since then I made a much slimmer, cheaper, more efficient version based on the ESP32 but I haven't written up much about that.
I also created my own keyboard with firmware in Rust
https://github.com/bschwind/key-ripper
I've done a bunch of other small one-off projects too.

2nd post about my first pcb(added pictures)
Good luck! I have an open source keyboard project in KiCad as well, feel free to reference or use anything from it.

Yet another keyboard post, or, introducing ErgoNICE
Not sure if the author of the post is around, but I guess this is a question for anyone who has designed keyboards: have you ever tried using shift registers for reading all the keyswitch inputs, and is it worth it? Does it mean you don't have to use a diode per switch?
I've designed my own as well but just went with the traditional key matrix with a diode per switch. Works well enough for the current size.

[Review Request] RP2040-based keyboard
All the source files can be found here
- Point keycaps? Yes.

Drop Giveaway Day 2 - 5x DCX Dolch Keycap Sets
I made my own keyboard layout just the way I want so I would put these caps on that, or replace the stock caps that came with my Filco board.

[Giveaway] PBTfans Deep Sea Predator/Twist
Twist looks awesome, I'd put it on my key-ripper

Can you run rust on the new raspberry pi pico w?
You can absolutely run Rust on the pico - I designed a keyboard with Rust firmware which runs on an RP2040. That being said, wireless functionality might not be existent yet in the Rust world for the Pico W, but I'm sure it won't take long to get added.

[Review] RP2040 Keypad
I looked at the schematic and it seems reasonable. I just completed an RP2040 project with USB C and it works correctly. You can see the project files here

Help with environmental parameters for a computer-controlled terrarium?
For controlling everything, the plan is to use a Raspberry Pi running Mycodo, which will connect to the the temperature/humidity sensors, and also control the LED lights, the misting sprayers, and the heating coil.

Grow light automation
As others have pointed out, there are quite a few alternatives already on the market, including open source ones. If you are attempting to turn this into a marketable product, you might be disappointed.

Fermentation Chamber 3rd generation
I'd also take a look at mycodo (here is the repo) which I personally found much more powerful than BrewPi and has an okay API I think if you want to set up your own frontend

IoT for hydroponics
Update: Found out about: MyCodo - https://github.com/kizniche/Mycodo (opensource Environmental Regulation System for rasbery pi) https://www.youtube.com/watch?v=nyqykZK2Ev4

Wireless sensors
Mycodo is great for the software side, but I don't think they have libraries for any wireless sensors.

Microsoft open sources its ‘farm of the future’ toolkit
There's tons of land unused in the US. But I also agree with you. I haven't played with this one yet, but it looks very nice

Timers?
Inkbird has a good reputation at a relatively low cost. Personally, I like to build my own systems using the Mycodo system running on Raspberry Pi W's.

Hydroponics: Growing an Appreciation for Plants
Here's my quick intro to hydroponics.
If you want bridge your grow with automation and coding I recommend everyone take a look at
https://github.com/kizniche/Mycodo
If you're looking for instrumentation/controllers for your grow (CO2, PH, TDS, EC) I recommend:
https://atlas-scientific.com/
If you're indoor and need lighting, build your own LED based lighting. Use the Samsung LM301B or LM301H led. I shopped https://atreumlighting.com/ for my last DIY kit and my light fixture came out perfect.
If you're buying nutrients or supplements, always try to get them in powered formula. Liquid based formulas are typically more expensive because you're paying to ship the water around and water is heavy. Most nutrient lines provide a feed schedule and dosing. When doing nutrients, less is more, never give them too much fertilizer, you will damage your grow and burn your plants.
Yes, I'm growing cannabis, you can see some of the fun we've had over the years at:

It’s less about the weed and more about the programming now. Having a blast with this little arduino. Two sensors per pot, 40 moisture-content readings per second. I also have data-logging capabilities via a data link from my laptop 🤙🏼.
Check out this environmental monitoring and control software I’m using on a raspberry pi with my grows, it’s amazing: Mycodo
