Bridge the digital and physical worlds by creating a custom hardware device that acts as a physical approval button for Claude. Use AI to write the low-level code and connect it to the Claude desktop app for a more tangible AI interaction.
Purchase a small, self-contained hardware device that includes an LCD screen, Wi-Fi, and Bluetooth. The blog post mentions one was found online for around $19.
Plug the device into your computer and open Claude Code. Instead of writing C code, describe your vision in plain English. Claude will figure out the Bluetooth protocol and write all the necessary code to make it work.
I want my little Claude to live on this thing, and I wanted to cheer me on every single time I do a good job, and also every single time I need to approve something that Claude is doing, I want it to be on this big button that is out here.In the Claude Desktop app, go to Help > Troubleshooting and select 'Enable Developer Mode'. The app will restart, and a new 'Developer' menu item will appear.
Click the new 'Developer' menu and select 'Open Hardware Buddy'. A window will pop up to scan for your Bluetooth device. Click 'connect' to pair your hardware with the Claude app.
Now, whenever Claude needs permission to perform an action (like writing a file), the hardware buddy will light up, make a sound, and display a prompt. You can physically press the button on the device to grant permission.
Create a personalized dashboard that automatically pulls in the latest data from your apps like Spotify, Gmail, and Notion. Design it once and let Claude's Live Artifacts feature keep it refreshed and relevant with a single click.
Turn a simple realtor's floor plan into a fully interactive 3D model of your house. Use AI to calculate dimensions, place your actual furniture by scanning emails, and create a virtual walkthrough before you move in.
Ensure UI consistency across projects by using AI to analyze your codebase and generate a 'living design system' in a single HTML file. This artifact acts as a portable, visual source of truth for you, your AI, and your team.
