NEW PROJECT WOOOO

I probably should’ve started writing this sooner

Anyways, welcome back! After Open Sauce, I’ve been brainstorming plans for my next build, ????? (you’re gonna have to check my updatelogs on github for the secret name :p), where there are some constraints on the build that I’ve planned that might require it to have a custom PCB…

Looking at that now, it might not happen, but who knows, fun to explore custom pcbs anyways! The goal for River? Basically to create a cursed setup where it just stores and plays music, which displaying some synced graphics, similar to something like the Internet Archive (and Milkdrop inside it)! It’s kinda an evil RP2040 devboard in a sense, which the twist being that… theres kinda two RP2040s (at least, the plan is). Simply, one is to work on the music, the second is to work as a display/graphics controller!

So, what’s been done? Currently, a LOT of benchmarking with circuitpython (and C (wow, scary!)) to measure whats a reasonable way to do this. As mentioned, we’re gonna probably have to use C for reasonable speeds for the graphics controller (which appears blazingly fast! no, not gonna try rust lol). Currently, 128x128 with an SPI interface seems like the plan!

Talking about the display, today (7/30/2026) has mostly been part sourcing, specifically for the display, as that’s what everything’s gonna have to revolve around! One was found (check the repo and today’s updatelog for the link), and CAD has started!

Well, that’s it for now! See ya in a bit!
