More Lights for your Presents

presLights

Lights on the tree? Check. Presents under the tree? Check. Lights in the presents? Why not! If your gifts don’t look festive enough and you have a spare inductive charging system lying around the house—though, you could always build your own from scratch—you can brighten things up by installing a few LEDs in the packaging.

The Instructable takes advantage of those new-fangled LED Christmas lights, one strand of which typically draws under 1A and requires around 5V, putting it in the ballpark for popular induction systems used to charge cell phones such as the Powermat. In this particular example, the strand ran off 3 AA batteries, or 4.5V, which meant stepping down the voltage either with a power regulator or, more conveniently, a simple diode in series.

Some additional modifications to the packaging tidy up the installation, including carving out some of the cardboard to recess the receiver and securing everything with hot glue before wrapping it all in paper. You can see a quick demonstration video below.

Keeping Christmas present hunters guessing with QR code gift tags

qr-code-gift-tags

[Thadd Brooks] is a geeky dad of the highest degree. His kids are constantly trying to figure out what mom and dad bought them for Christmas, while he continues to think up ways to stymie their progress. He certainly could have put a few prank presents under the tree, but he opted to go a different route, confusing his smartphone-wielding kids with QR codes.

Each gift under the tree bears no name tag, rather they are adorned with a single QR code sticker which [Thadd] printed out. When scanned, the code brings his children to a page on his web server stating who the gift is for.

The catch? Well, the codes bring up a random page each time, attributing the gift to every member of the family along the way. There’s no chance that any of the kids will be able to correctly identify their gifts before Christmas Eve, when [Thadd] flips a switch on the server and reveals the actual gift recipients.

It’s certainly a clever, yet frustrating, way to keep his family on their toes, and we think it’s a pretty awesome idea.
