Don't Toss That Old Tech Yet: Smart Ways to Reuse Webcams, Routers, and Old Phones

The world generated a record 62 million tonnes of electronic waste in 2022, up 82% from 2010, according to the UN's Global E-waste Monitor. Less than a quarter of it got properly collected and recycled, and that number's on track to hit 82 million tonnes by 2030.

Meanwhile, the right to repair movement has been gaining real traction, with several states now requiring manufacturers to make parts and repair info available instead of nudging people toward buying something new. Giving old devices a second life before the landfill isn't just a way to save a few bucks anymore. It's part of a bigger shift in how people think about all that tech piling up in a drawer somewhere.

So before you toss that old webcam, router, or smartphone, here are a few practical ways to put them back to work.

Webcams Can Become Security Cameras

Most computers today have built-in cameras, so a lot of older stand-alone webcams end up sitting unused. Rather than letting one collect dust, you can turn it into a basic home or office security camera.

Reconnect it to a computer using its original USB cable, then install software that records footage continuously or only when it detects motion. iSpy Connect is a free option that's still actively maintained, and it supports unlimited cameras and microphones, motion detection, scheduling, remote access, and password protection.

Routers Can Become a Smart Home Access Point

A smart home setup needs solid Wi-Fi coverage everywhere, and an old router can help stretch that instead of gathering dust in a closet. Most routers include a built-in access point (AP) alongside their routing function, and that's what actually broadcasts the Wi-Fi signal your smart devices connect to.

Connect the old router to your current one and set it up to work as an external access point instead of a second router. PracticallyNetworked's guide to converting a router into an access point walks through the setup, which mostly comes down to disabling the old router's DHCP server so it doesn't conflict with your main network.

PC Fans Can Generate a Little Power

If you're retiring an old desktop, the CPU cooling fan inside can be turned into a tiny wind-powered generator. It's not going to power much, usually just 1.5 to 2 volts in an 8 mph wind, but it's a fun little project if you like tinkering. Creative Loafing Tampa's guide walks through how to wire it up.

Old Smartphones Have More Life Left in Them

Smartphones pile up faster than almost anything else, mostly because manufacturers release new models so often. But a phone that's no longer on a cellular plan can still earn its keep in a few different ways.

Home or Office Music System

An old phone works fine as a control center for a speaker system, streaming from a saved library or a service like Spotify or Pandora. Worth downloading a podcast app or two while you're at it if you want more out of it than a basic playlist.

HUD System for the Car

A head-up display (HUD) projects things like speed and navigation onto the windshield, so you're not glancing down at a dashboard while driving. Navier HUD is still actively maintained and free to try on Android, and similar options exist for iOS through the App Store. Once it's installed, just prop the phone on the dash so its reflection shows up on the windshield.

Digital Photo Frame

An old phone propped on a stand or shelf makes a surprisingly good digital photo frame. Load it up with a folder of photos and use a slideshow app, or set your photo gallery app to cycle through an album automatically. Plenty of phones already have this built in as a screensaver option when the device is charging, so it might not even take an extra app. Google Photos, for example, lets you build a slideshow from a specific album, and the native Photos app on iPhone has a similar option. A basic phone stand works fine to prop it up, and it's worth leaving the phone plugged in since it'll likely be running the screen non-stop.

VoIP Phone

An old smartphone with no active cellular plan can still make and receive calls, all it needs is Wi-Fi and the right app. This might be the most useful of all these ideas, since it turns a phone that would otherwise just sit there into a real, working business line.

The easiest way to do this is with an app like the Telzio Mobile App. Connect the old phone to Wi-Fi, download the app, and it becomes a secondary business line backed by a full VoIP phone system, no need to buy a dedicated IP phone. It comes with the same core features you'd get on a desk phone, caller ID, call recording, call transferring, conference calling, so that spare phone can become a real extension for an employee, a second line for yourself, or backup coverage when things get busy.

Give Your Old Tech a Second Job

None of this takes special skills or much of a budget, and it keeps working devices out of a waste stream that's growing a lot faster than recycling can keep up with. Pull that old gear out and see what it can still do.
