I’m so tired, man

looking at the schematics of the device I want to monitor more closely, it looks like it’s actually using addressable LEDs with a two-wire protocol, which actually makes things even easier because I can just sample on the provided clock edges. I think these are colloquially DotStar rather than NeoPixel devices. For reference I’m designing some mods for a modern pinball machine and it would be useful to know the state of lights on the playfield since I can’t hook into the code directly.

well, it’s more being able to detect long vs. short pulses, as it’s not the logic level but the pulse width that encodes the bits.

fortunately the RP2040’s programmable IO can run at 40x that 3MHz rate, so with a working program I should be able to differentiate short and long pulses and convert them back to bits. My application shouldn’t need to know exact colors, rather just detecting certain patterns or an on/off threshold state for a specific light in the chain.

This is not true, datacenters are bad, but this is not why. Here’s a good post re. this “study”

Data centers’ heat exhaust is not raising the land temperature around where they’re built

I’m selfhosting a gitea instance now. If anyone wants to host some code on an optiplex tower in my spare bedroom, pm me and I’ll make you an account. Absolutely zero uptime guarantees, but also absolutely zero AI.

all of the computers in my house run linux, and other than a few laptop hardware issues my non-techie wife uses it for all of her work happily. Sure I can’t play Fortnite, but other than that sort of edge case I never see myself going back. My dual-boot windows install has been left to rot on my desktop and I don’t think it’s even worth the time investment of updating by firing it up again.

bookmarking this to read later, thanks for sharing! Loved the game as a kid, and it’s still fun to pick up and play on literally any hardware now :D

I just went in and opted out, but setting up my sellfhosted gitea instance has just moved to the top of my todo list. I already have a postgres database server running, and a VM where I can run docker containers so I’m excited to get all of my code out of there.

I’ve been bitten before, hence all the extra cable. He’s a lot less wire-crazy than our other bunnies. They aren’t allowed in here 😆

edit now the link actually goes to what I meant to post, the bunny will have to go here:

Really cool idea, hoping to see updates on the project as it goes!

I really like the gardening analogy. It also feels that way from a user’s perspective since I’m not getting content fed to me by an algorithm, I’m seeking out users and communities to follow and cultivating my own feeds
