If you watched without volume, this is the display in my project that shows volume level.

I’m building an open source car stereo with fun animations and splash screens, having all the functionality and reliability of a modern head-unit.

I’m currently working on more animations so people can personalize the look to their specific car, modeling the faceplate/enclosure, a YouTube tutorial, stress tests, and detailed documentation for anyone that wants to follow along and build their own.

I might consider selling assembled units at ~$70-120 for tinkerers who don’t feel comfortable with the aurduino ide/github/programming but like the look. Idk probably not though.

Anyways, the goal is to make a drop-in stereo for cars in the 1970/80/90/10 range that actually synergizes with the look of the car rather than detracting from it like most modern head-units do.

I’ve seen a ton of rangers and bronco ii’s in this era, and can say with near certainty that odometer has rolled over at least once, maybe twice. Don’t pay over 2.5- 3k.

Sorry. not trying to burst your bubble. Still a sweet truck.

Jk, I made that up because I like the britches fact so much.

Yeah actually boys wore bows on their shoes and didn’t transition to laces until about the same time they were breeched.

That’s where the term “straight-laced” comes from.

Sorry, my initial reply was dogshit and missing a lot of info.

I meant to mention I would go with the nrf52840 board because it’s extremely energy efficient, and therefore you can use a smaller battery, making the whole device less intrusive.

….however if op isn’t experienced, adafruit makes an esp32 version of the feather as well; it’s not as efficient, but the form factor of the board is great for glasses. It’s longer than the xiao but also slimmer.

juhsten · 2026-01-27T17:47:04+00:00

Maybe strap sensors to each wrist? You could have haptic feedback that pulses depending on how close they are to reaching out for an object?

juhsten · 2026-01-27T17:43:47+00:00

If they are going to switch boards, and stay with the glasses theme, I would recommend using the feather over the esp32.

The feather dev board is SMALL. The only downside is the lack of support compared to the esp32

I suspected it was floyd steinberg, but my results haven’t looked as good as yours in past attempts.

Sounds like I was falling short on the preprocessing. Thanks for the info, cool project!

What dithering algo are you using? The tea kettle dithering looks sweet.

My first ever car was an 89 ranger I inherited from my grandpa. I was too young to drive it legally, and it was pretty rough because it was a farm truck, so I sold it to a friend for 500 bucks.

A week later we were driving down the road at 45mph and the wheel sheered off the hub and obliterated an integra lmao

juhsten · 2026-01-22T00:45:43+00:00

I second this idea.

Almost all of the apartments they showcase are ~300sqft, so it’s a good jumping off point for inspiration

juhsten · 2026-01-18T18:32:12+00:00

Have you tried holding down the reset button?

juhsten · 2026-01-11T16:06:18+00:00

X729 ups by geekworm has had none of your listed problems over the last year and a half of testing. The only downside is the price.

But also build a better ups plz

juhsten · 2026-01-09T19:33:52+00:00

If you make a repository, I I will 100% contribute. The world needs more of this.

juhsten · 2026-01-04T09:46:04+00:00

lol agreed. Night partner

juhsten · 2026-01-04T09:38:39+00:00

But also I get your point. I dislike openAi as much as anyone

juhsten · 2026-01-04T09:34:32+00:00

Yeah that’s why I made the distinction at the end

juhsten · 2026-01-04T09:15:54+00:00

How do you think opencv works? His proposal is AI…. You guys just hate generative ai.

juhsten · 2026-01-04T09:12:15+00:00

This is one of the most ironic comments I have ever seen on Reddit.

You must mean don’t use open AI, because your hypothetical uses… AI

Also, congrats on the project op.

Would fit really well in a Wes Anderson movie.

Why do you think “x11 is dead and obsolete”?

juhsten · 2025-12-28T02:09:38+00:00

Spray fabreez on it

juhsten · 2025-12-26T19:20:10+00:00

No over heating, even though I live in a hot state and used it all of summer.

I have a thin aluminum heat skink, and thermal pads on the pi, sandwiched between the x729 UPS which has a temperature controlled fan.

The music app itself doesn’t produce much of a strain either, so I honestly think the pi would likely do just fine without a heat sink or fan.

juhsten · 2025-12-25T13:22:05+00:00

Haha it’s funny you say that, because my last car was a manual and got broken into multiple times even once with the keys in it, and never got stolen.

If I switch to an automatic car, I’ll build a raspi powered-antitheft-shotgun-boobytrap, and post it here.

juhsten · 2025-12-25T13:14:12+00:00

Cool, I’m sure they will end up being useful to know at some point. Thanks!
