Hello Nexus vs Open Adaptive Switch

Nexus turns your phone into a live dashboard and control surface for the computer you game and work on. Pair once with the free Nexus app on your Windows PC, Apple Silicon Mac or Linux PC, then build a panel of widgets you can reach from the couch, the desk, or the other side of the house. WHAT YOU CAN DO - Watch CPU, GPU, memory, temperature and fan readings update live, as gauges, sparklines or full-screen charts. - Control your RGB lighting: pick an effect, set colors and brightness, and give each device its own look. - Tune cooling: switch presets, edit fan curves against any temperature sensor, and see every fan respond. - Run playback, system volume, the per-app audio mixer and your monitors' brightness. - Drive OBS: switch scenes, start and stop streaming or recording. - Build a deck of custom keys for shortcuts, hotkeys, launching apps and one-tap system actions. - Keep an eye on processes, storage, network and overall system health. - Fill the rest of the grid with clock, weather, stocks, calendar, photo gallery and more. A PANEL YOU DESIGN Drag widgets around the grid, resize them, spread them over several pages, and tap any of them to open a full-screen view with the detailed controls. Your layout stays in sync with your computer. SEND THINGS TO YOUR PC Share files, photos and links from any app straight to your computer, or push clipboard text across in a tap. CONNECTED TO YOUR OWN MACHINE Your phone talks to your computer, not to a middleman. Pairing is confirmed on both ends, the session is pinned to your computer's own certificate, and an encrypted relay carries the connection only when you are away from your network. WHAT YOU NEED Nexus for Windows, macOS or Linux, a free download from hellonexus.com. The app on your phone is free too, with no account required.

Open Adaptive Switch is the companion app for a do-it-yourself Bluetooth accessibility switch. It lets a caregiver set up and manage the switch from an iPhone or iPad, with no cables and no computer. Please note: this app requires the matching hardware. Open Adaptive Switch is an open-source switch that you build yourself from inexpensive parts (a Seeed XIAO nRF52840 board, a button, and a small battery) for roughly ~$15. Full build instructions and firmware are free at github.com/mikavj/open-adaptive-switch. Without the hardware, the app has nothing to connect to. The switch works with iOS Switch Control, so a single button press can tap the screen, run a recipe, or drive the scanner, giving people with limited mobility an affordable way to use an iPad or iPhone. With the app you can: Choose the key the button sends, from a full list including the F13-F24 keys that pair cleanly with Switch Control, plus letters, numbers, and common keys, with modifiers. Switch between single-key, tap-or-hold, and short/medium/long press modes, so one button can trigger up to three actions. Set how long the switch waits before it sleeps to save battery. Rename the switch and pick a color in the app to match the button you built. See the battery level and charging state, including in the list of nearby switches before you connect. Install firmware updates over Bluetooth, choose any released version, or roll back if needed. The app collects no personal data. It uses Bluetooth to reach your switch and contacts GitHub only to check for firmware updates, which you can turn off. Open Adaptive Switch is free and open-source, built to make assistive technology affordable for families, classrooms, and anyone who needs it.
