Here is the hacked together *DashPack*, a tiny CAN‑bus interface that listens for the window‑up switch in my 2018 Porsche Macan and plays movie quotes through the car’s AUX input. It gives passengers (especially kids) something fun to do that doesn’t involve touching any “unsafe while driving” controls.

---

### Why?

* The only controls reachable by back‑seat passengers that don’t affect driving are the seat and window switches. * A single, familiar control with two modes:

* **Short press** – triggers a *random* clip (e.g. a “pew‑pew” laser sound). * **Auto‑up hold** – triggers a *known* clip (e.g. Spaceballs: “Thank you for pushing the self‑destruct button”). * Adds a bit of shared, in‑car comedy without screens or Bluetooth headaches.

---

### How it works

1. *Hardware*

* Raspberry Pi (or any Linux box with `socketcan`) * USB‑to‑CAN adapter (I used an InnoMaker USB2CAN) * 3.5 mm audio out → car’s AUX jack (I used a cheap 2.4 GHz TX/RX pair to hide the Pi in the cargo area) 2. *Wiring (Macan 2018)*

* Comfort CAN at the gateway under the rear bench * Pin 5 = CAN‑L * Pin 15 = CAN‑H * Posi‑tap, run two wires through the stock conduit, DONE. 3. *Software*

* Python (`python‑can`, `pygame`, `playsound`) * Reads CAN ID 0x3D0 and decodes the *window‑up* bits * Picks a WAV/MP3 from `sounds/`, launches `mplayer` * Autostarts via a `.desktop` file so it survives key‑off/on cycles 4. *Testing*

```bash # virtual CAN sudo modprobe vcan sudo ip link add vcan0 type vcan sudo ip link set up vcan0 # simulate a window‑up frame every second cangen vcan0 -I 3d0 -D 0000140085 -g 1000 ``` ---

### Caveats

* *Vehicle‑specific:* Only confirmed on a 2018 Macan Base. Other Porsches → new CAN IDs & pins. * *Hackish:* No guarantees, warranty, or safety claims. Tap the wrong wires at your own risk. * *Audio:* I avoided Bluetooth on purpose; AUX + analog TX/RX has 0 pairing issues and \~0 latency.

### Repo / Docs / Pics

[https://github.com/your‑user/dashpack](https://github.com/your‑user/dashpack) – full wiring photos, CAN logs, and a list of quote clips in `sounds/`.

---

### What’s next?

* Hooking HVAC and seat‑vent messages for more “passenger superpowers” * Car‑agnostic bus sniffing to auto‑learn switchgear IDs * Maybe an “Arduino‑only” build so folks don’t need a Pi

---

I’d love feedback on:

* Better ways to detect switch events across different Porsche models * Safer/cleaner CAN tap ideas * Creative sound clip suggestions (short lines that always get a laugh)

Hi HN -

I'm excited to share a free, local, open-source AI app builder that I created. You can see what it looks like and download it here: https://dyad.sh/

It's open-source and on GitHub: https://github.com/dyad-sh/dyad

If you've used one of the popular AI app builders like lovable, v0 and bolt, but want something more flexible and without the lock-in, I think you'll like dyad.

Here's a few things that makes it different:

- Runs locally - Dyad runs entirely on your computer, making it fast and frictionless. Because your code lives locally, you can easily switch back and forth between Dyad and your IDE like Cursor, etc.

- Run local models - I've just added Ollama integration (https://www.dyad.sh/docs/guides/ai-models/local-models), which lets you build with your favorite local LLMs.

- Free - Dyad is free and bring-your-own API key. This means you can use your free Gemini API key and get 25 free messages/day with Gemini Pro 2.5!

Note: dyad isn't an IDE (and not another VS code fork :) and instead is focused on people, esp. non-coders, who want an all-in-one tool to build+preview web apps in a simple intuitive desktop UI.

I’d love any feedback. Thanks!
