1. Old Phone = Smart Home Command Centre
Your outdated smartphone can become a smart home dashboard.
Tools You’ll Need:
- Free apps like Home Assistant, Google Home, or Samsung SmartThings
- A cheap phone stand or magnetic wall mount (under £10)
Use it to control lights, thermostats, speakers, and security cameras. Bonus: Turn on “do not disturb” and it becomes a dedicated control hub.

2. Tablet = Digital Picture Frame or Recipe Screen
That crusty old iPad? Mount it in your kitchen and load up:
- Google Photos Slideshow for a dynamic digital photo frame
- Paprika Recipe Manager or Tasty app for a swipe-and-cook screen
Add a cheap tablet stand (£8–£12), and voilà—your cooking companion or memory display is ready.
3. Laptop = Chromebook Clone
Old laptops still work—they just need a lighter OS.
Try this:
- Install ChromeOS Flex (free)
- Upgrade to SSD storage (~£20) for a major speed boost
- Add more RAM if it’s below 4GB (budget sticks cost ~£25)
You’ll end up with a clean, fast browser-based device perfect for emails, browsing, and cloud apps.

4. Phone + Webcam = Wireless Security Camera
With free apps like:
- Alfred Camera
- Manything
- IP Webcam
…you can repurpose a spare phone into a motion-detecting security cam. Mount it at the front door or living room, and monitor remotely via your main device.
Spend £5 on a tripod or corner mount and you’re good to go.
5. Echo Chamber: Turn a Bluetooth Speaker + Old Phone into a Voice Assistant
Pair your unused Bluetooth speaker with an old smartphone running Google Assistant or Amazon Alexa app.
Bonus idea: Stick it in the bathroom or kitchen for voice-controlled music and timers while you wash dishes or take your karaoke shower sessions to the next level.

6. Raspberry Pi Magic
If you’ve got an old monitor or keyboard lying around, a £35 Raspberry Pi 4 can turn it into:
- A retro gaming console
- A private VPN server
- A smart mirror interface
- A low-energy web server for testing projects
All for under £50, including accessories.
7. Old Monitor = Second Screen for Productivity
Got a dusty monitor? Grab a DisplayLink adapter (around £20–£30) to connect it to your current laptop—even if you’re on a MacBook with no HDMI.
Use it as a dedicated window for Slack, Notion, or Zoom.
Multitasking = Unlocked.

8. DIY Smart Mirror from Old Tablet or Monitor
This one’s fancy but doable. You’ll need:
- An old monitor or tablet
- A two-way mirror acrylic sheet (~£15)
- A simple frame
- Raspberry Pi or Android apps like MagicMirror²
Mount it in your hallway or bathroom. It shows the time, weather, calendar, and news—all while reflecting your fabulous face.
9. Old Phone = Kids’ Entertainment Hub
Install YouTube Kids, ABCmouse, or PBS Kids. Put the phone in a durable case (£10–£15), download shows offline, and you’ve got a portable entertainment system without risking your main device.
Parental controls included, peace of mind guaranteed.

10. Mini Music Server or Offline Radio
Install Plex, Spotify (offline mode), or VLC Media Player on an old laptop, tablet, or phone.
Connect it to a speaker or aux cable. You’ve now got a dedicated home music hub or retro DJ booth.
Final Tips for DIY Upgrades on a Budget
- Clean first. Factory reset old devices, clear cache, and uninstall bloatware.
- Power it right. Invest in good charging cables or battery replacements (£10–£20).
- Wi-Fi only is fine. Most of these hacks don’t require a SIM card.
- Use cases and stands to keep setups neat and functional.

Closing Thought
Smart doesn’t mean expensive. With just a few pounds and a pinch of DIY spirit, your forgotten gadgets can become part of your smart tech setup—enhancing your home, productivity, and creativity.
Give your old tech a second chance. Who knew recycling could be this clever?
