How to Capture     on    using   

This guide explains how to locally record raw audio from Microsoft Teams on a Mac using OBS Studio. This method avoids using Teams' built-in recording or third-party bots. Nobody in the meeting sees a recording banner or a bot joining, and the file stays on your Mac.

Important

Ofc, tell the participants that you are recording.

Prerequisites

• macOS 13 (Ventura) or newer. The app audio capture used here does not exist on older versions.

RP2040 boards + arduino-cli on Raspberry Pi (headless): setup notes

Flashing an RP2040 board (tested with a Waveshare RP2040-Zero) from a Raspberry Pi over SSH using arduino-cli. Written for a first-time setup. Notes from actual trial and error.

Things that will differ on your machine are marked like <this>. Pay attention to usernames, serial ports, and file paths: do not copy-paste those blindly.

1. Install arduino-cli and fix PATH

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh

How to run a full screen browser (web-app) on a non-GUI Pi-OS

Context (Problem)

Imagine you have an embedded-system prototype running on a Pi 5 SBC, but you need a lightweight OS—for example, to boot faster. Typically, if you don’t need a GUI, you might use something like DietPi or the Raspberry Pi OS CLI (non-GUI) version. But what if you do need a GUI? Preferably a web app? Here’s a helpful nugget if you’re facing that scenario …

Approach

I didn’t realize that these days we can display a Chromium frontend on this minimal OS without installing a heavy, full-blown desktop environment. Since the Pi 5 (our target) defaults to modern Wayland graphics, we can use a “kiosk” approach. This runs a lightweight Wayland compositor whose sole job is to draw the Chromium browser directly to the assigned external display, saving RAM and CPU for other processes.

Listing Cameras (Multi-Cam Scenario)

To reliably list attached cameras and see which /dev/videoX path corresponds to which device, the best tool is v4l2-ctl.

First, install the utility if you don't already have it:

sudo apt upgrade -y

Migrate Raspberry Pi 5 from SD card to NVMe SSD (headless / Pi OS Lite)

Clone a running Raspberry Pi OS install from the microSD card to an M.2 NVMe SSD (via the Pi M.2 HAT+) and boot fully from the SSD. No desktop, all over SSH.

Tested on: Raspberry Pi 5, Debian 13 (trixie), Pi OS Lite 64-bit, 256 GB NVMe.

Tip

Why not SD Card Copier? That is a desktop GUI tool. On a Lite/headless image, it does not exist. This guide uses rpi-clone instead.

Hunyuan3D-2.1 in ComfyUI on Linux — Field Notes

What it took to get visualbruno/ComfyUI-Hunyuan3d-2-1 running reliably on Linux with PyTorch nightly + Blackwell

---

Why visualbruno/ComfyUI-Hunyuan3d-2-1 ?

1. The default Hunyuan3d-2.1 workflows in Comfy Do not bake texture.
2. kijai/ComfyUI-Hunyuan3DWrapper is a little behind and mostly targeted for Win installs and older py torch

Raspberry Pi Tmux Dashboard on Boot

Auto-launch a tmux monitoring dashboard on Raspberry Pi boot (headless/CLI). Press any key within 10 seconds to skip and drop to shell.

Note

I use this for a pi that I carry on-site, either when I'm teaching or on a client side, where I need a MQTT broker and also where wifi setup shoudl be easy (So, my pi is running: headless pi wifi configurator)
