Using a Raspberry Pi-powered deadbolt actuator, multiple users can remotely unlock a door via a smartphone app.
The build can be attached to your existing lock, so there’s no need to start pulling out the inner workings of your door.
The app will also notify you when the door has been unlocked, offering added peace of mind when you’re away from home.
For a full run-through, check out their video below.
You’ll need access to a 3D printer for some of the parts and, as a way to support their growing channel, the team provide printed parts for sale on eBay.
You may also wish to check out their other Raspberry Pi projects too. They’ve made a lot of cool things, including a Facebook Chatbot, a Portable Arcade Console, a Smart Mirror, and a Motion-tracking Nerf Turret.
And in celebration of hitting 50k subscribers, the team are giving away two Raspberry Pis! Just subscribe to their channel and tell them how you would use one in your own project to be in with a chance of winning.
If you have built your own Raspberry Pi-powered lock or security system, we’d love to see it. So go ahead and share it in the comments below, or post it across social media, remembering to tag us in the process.
