Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol). I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, e…

I'm already working on something like this and have a prototype board designed.

Here is my version 1.

Version 2 is being built around a CM4 IO board and will include my AVCLAN implementation, DAC, GPS and is intended to run AOSP Android. The board is fully designed already and I'm working on the custom Android build now.

Godspeed. I find it frustrating these systems don't follow some sort of international standard, still. I can't justify replacing the system in my 2016 Highlander just to get Android auto, but the Bluetooth system handles non-phone calls poorly and the album art database hasn't been updated for basically the entire life of the vehicle. I don't like having to rely on the manufacturer nor Google/Apple for connectivity basics.

Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.

So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox

A tree cutting tool. Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree. The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side). I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping…

Do consider the value of the wood in relation to your cuts. A well-placed cut not only guarantees safety but will also take the maximum board feet from the tree.

i work a lot with NVEL for this. one time even tried porting nvel to wasm for fun and client accessibility. we "virtually buck" trees which seems like could be applied to your proposed use case. if op wants to go down this path: https://github.com/FMSC-Measurements/VolumeLibrary/tree/77d4...
