In the dark ages, you had to use a key to lock and unlock your car doors. Just about every car now has a remote control on the key that lets you unlock or lock with the push of a button. But many modern cars don’t even need that. They sense the key on your person and usually use a button to do the lock or unlock function. That button does nothing if the key isn’t nearby.
[Pierre Charlier] wanted that easy locking and unlocking, so he refitted his car with a Keyduino to allow entry with an NFC ring. What results is a very cool fistbump which convinces your car to unlock the door.
Keyduinio is [Pierre’s] NFC-enabled project, but you can also use a more conventional Arduino with an NFC and relay shield. The demo also works with a smartphone if you’re not one for wearing an NFC ring. Going this round, he even shows how to make it work with Bluetooth Low Energy (BLE).

If you’re looking to add a bit of the future to your living room, you might want to look at this tutorial to build a very professional infinity mirror table.
It’s an IKEA RAMVIK coffee table, modified to include RGB LEDs and a one-way mirror for that ever-so-awesome infinity effect. And technically, you only have to cut one hole in the table.
By placing a large mirror underneath the glass, wrapping the inner edge with a strip of RGB LEDs and coating the original glass top with a reflective car tint, it’s a pretty simple hack that results in a very polished product — not something that can be said for most of our projects! But to make it even better, [Pierre] added an NFC chip under the table, allowing you to control the color with just a tap.
