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.

FuryGpu – Custom PCIe FPGA GPU
The RP2040 is a great MCU for playing with graphics as it can bit bang VGA and DVI/HDMI. There's some info on the DVI here: https://github.com/Wren6991/PicoDVI
I wrote a couple of articles on how to do bit banged VGA on the RP2040 from scratch: https://gregchadwick.co.uk/blog/playing-with-the-pico-pt5/ and https://gregchadwick.co.uk/blog/playing-with-the-pico-pt6/ plus an intro to PIO https://gregchadwick.co.uk/blog/playing-with-the-pico-pt4/

Video Game Module for Flipper Zero
A few years back someone was bit banging DVI and 720p 30fps video straight off the RP2040 GPIO pins with just inline resistors between not and the HDMI cable.

VGA driver using PIO and DMA on the RP2040
I have the Adafruit DVI board and have been hacking on it some. It's more fun than should be allowed.
There's a project to get this running using Rust[1]. Currently it outputs the blue channel with sync, but has trouble with the other two channels. I don't have a hardware lab with scope, logic analyzer, etc., so it's not easy for me to debug.
In the meantime, I've been doing some experiments in the C codebase as well[2], mostly in the direction of proportionally spaced bitmap text, using the fonts in the X11 distribution.

Recommend MCU with dual USB - one host and one device IF?
There is even bit-banged DVI library for pico.

Show HN: PicoVGA Library – VGA/TV Display on Raspberry Pi Pico
Apparently, there is a digital video output project for the RP2040 already out there [0]! As for why digital video is more rare, it is because the common digital video formats are higher bandwidth and require higher signal integrity.

Least resourceful 18 year old air defense ukrainian soldier with basic coding abilities
I've seen people implement DVI with PIO, and I'm sure basic missile commands wouldn't be as bandwidth-intensive as that.

Help understanding current-mode and TMDS logic in DIV/HDMI.
For example this guy (https://github.com/Wren6991/PicoDVI) essentially 'bit bangs' CML. Sure its not a completely compliant implementation, but it's pretty close... In his case using a push pull with 3.3V/0V. I don't know how he's getting a 0.8V swing.

Anyone know where I could obtain these
I’ll do you one better: Here is the WLED main site - they cover everything - however you want it for your vehicle is up to you! (If you want to see a truck I personally worked (with 2 other main guys doing the woodwork and wiring) on that was probably the “most expensive” project with these controllers, check out the SEMA entered “Realtree Stormtrooper truck” - a LOT of time went in to that and almost a year of prep, not a fan myself, but custom electronics are what I like doing)

The perfect WLED board... is not working.
Did you use the esp32.bin? If so, you should instead use ESP32-C3 here: https://github.com/Aircoookie/WLED/releases/download/v0.14.0/WLED_0.14.0_ESP32-C3.bin

How do I get LED strips here? My plan is to use Govee H619A and PVC U profiles again (like in the last pic) for the green part but how do i get electricity up there? the outlet is X'ed 'cause theres gonna be a shower right under it and theres only one more outlet next to the sink in pic 2

An idea I had for a power injector for use with bullet pixels left me with questions.
I feel like I should start this post with a disclaimer. I tend to over-complicate things. Which means I'm making this post partly as a sanity check and partly to fill in some gaps in my kno.wled.ge
