How to reuse an old Chromecast in 4 smart ways

Chromecast beyond streaming

Your old Chromecast isn’t just for Netflix or YouTube; even if you upgrade to a newer device, the old dongle can still be useful. With a bit of imagination and the right setup, it can serve multiple purposes around the home.

Instead of letting it sit unused, you can repurpose it to extend value. This slideshow explores various creative and practical ways to reuse an old Chromecast. Let’s turn that spare gadget into a useful tool.

Turn your TV into a photo frame

You can use Chromecast to cast photos or slideshows from your phone or computer, turning your TV into a large digital photo frame. Just open your album (e.g., in Google Photos), hit the cast button, and send it to the Chromecast-connected TV.

It works great for displaying family photos, holiday memories, or even art slides for ambience. For gatherings or cozy evenings, this simple trick breathes new life into your TV. A virtual fireplace or scenic image loop can make the living room feel more inviting.

Use phone screen mirroring

Chromecast supports full-screen mirroring from compatible Android phones and from the Chrome browser on a PC or Mac. That means you can show webpages, documents, presentations, or apps directly on your TV. Want to browse photos, show PDFs, or demo an app on a bigger screen?

Casting your screen makes it easy. It’s useful when your smart TV apps don’t support certain content, or when you want to share something from your phone with a group. This turns your TV into a big display for almost anything on your device.

Cast music to soundbar or TV speakers

If you connect your Chromecast to a soundbar or TV setup, you can stream music or podcasts from apps like Spotify or other cast-enabled services. This turns your old TV setup into a full-fledged audio system even without video.

It’s a low-cost way to reuse hardware and enjoy better sound. Especially useful for living rooms or parties where you don’t necessarily need video. Chromecast still works fine as a “music player” hub.

Display live camera and security feeds

For homes with smart-home cameras (for example, from Google Nest or other compatible systems), you can cast their live video feed to your TV using a Chromecast with Google TV or another compatible Chromecast device.

That way, a TV becomes a dedicated security monitor handy for watching the front door, baby room, or backyard.

It’s a convenient way to keep an eye on security without needing a dedicated screen. Instead of buying a separate monitor or tablet, your Chromecast + TV combo does the job.

Use for presentations or slideshows

If you need to show slides, photos, documents, or web content to a group, say in a meeting, class, or family gathering, a Chromecast plugged into any HDMI screen works great. From your phone or laptop’s Chrome browser, you can cast your content to the screen instantly.

This turns almost any display into a presentation monitor. It’s a handy, portable solution for business, study, or social use, especially when you don’t have a projector or smart TV.

Create a DIY media server hub

Pairing Chromecast with a media-server app like Plex lets you stream your own collection of videos, music, and photos stored locally, effectively turning your TV into a home media center. Instead of relying on paid streaming services, you stream your own library.

All you need is to install Plex (or similar) on your phone or PC, connect Chromecast, and enjoy your media on the big screen. It’s a great way to reuse old content like movies, anime, or family videos. This works even if you’ve cut the cord on paid streaming subscriptions.

Build a retro gaming console

If you have a Chromecast with Google TV or another compatible Google TV streaming device, you can install or sideload emulators and run retro games, turning your spare Chromecast + TV into a budget gaming console. Classic games with simpler graphics often run smoothly.

It’s a cool project for nostalgic gamers, reminiscent of old-school platformers or 16-bit titles. While not ideal for heavy 3D games, for retro gaming, it’s a fun, low-cost way to get more use out of your old hardware.

Turn your TV into a home dashboard

You can cast a customized dashboard like weather info, calendar, news, to-do lists, or family schedule from your phone or a browser tab to the TV. With a Chromecast plugged in, your TV becomes a control center that everyone in the home can glance at.

Ideal for kitchens, living rooms, or common spaces where you want easy access to daily information. It’s a practical way to repurpose the TV beyond movies and shows.

Make TV a digital cookbook display

For kitchen use: cast recipes, cooking videos, or measurements from your phone or browser to your TV. Instead of juggling a phone or tablet while cooking, your Chromecast + TV setup becomes a hands-free cooking assistant.

It’s especially useful when you’re busy chopping or mixing; a glance at the screen is easier than handling a small device. A good way to reuse old hardware for everyday home tasks.

Stream educational content for kids/family

Even if kids outgrow shows and movies, Chromecast can still be used to cast educational videos, documentaries, or tutorials from the web to the TV. This makes learning group-friendly, since everyone can watch together.

For homeschooling, group study sessions, or casual learning, it’s a cheap and convenient medium. It gets extended life even without new streaming subscriptions.

Emergency entertainment for guests

Got guests over, but no smart TV? Plug in the old Chromecast, cast a playlist, music, or slideshows, and you have instant entertainment or background ambience. It’s inexpensive and flexible. Instead of spending on a new streaming device, reuse what you already own.

Great for parties, family gatherings, or casual get-togethers. The Chromecast stays useful even if you’ve upgraded your main system.

Old Chromecast stays useful

An old Chromecast doesn’t need to be thrown away with a few tweaks and some creativity; it can serve many roles: media server, music player, gaming box, security monitor, kitchen assistant, and more. Its versatility comes from simple casting and HDMI compatibility.

Even if it’s no longer ideal for the latest streaming, it remains a handy, low-cost streaming hub or display adapter. Before tossing it, consider repurposing. You might be surprised how useful it still is.
