Christmas is a time for family, friends, holiday cheer, and if you’re a techie, try to avoid these as much as possible. Even with all the holiday obligations, no work, and a lot of stuff closed, you still get a lot of free time. And how best to fill this free time? A DIY project or two.
Even better, if you take on a Christmas themed project, you can pretty much claim to be getting into the holiday spirit by locking yourself in with your favorite soldering iron and Arduino. If you have some family obligations to fulfill, you can simply let the children help. Holidays are really the perfect time to do your own thing.
Let’s take a look at seven great project ideas you can do during the Christmas holidays.
Christmas snowball lights

Regret buying those sticky Christmas lights? It doesn’t take much to turn them into something more special: just a ping pong box and a workout. User Instructables hboom does it in this super simple Christmas themed project. Sometimes you don’t have to go all-in with Arduinos and Raspberry Pis to make something cool.
By putting every bad LED in a ping pong ball, you can turn the worst Christmas lights into beautiful glowing balls. With half an hour of your time and a few dollars, it’s easy to dress up decorations this Christmas.
Control your Christmas lights with Arduino

If you want to get a little more involved, you can use an Arduino and a Raspberry Pi to take full control of your Christmas lights. You can create static or dynamic templates like in the video above. Osprey22, another Instructables user, has created a tutorial that shows how to do this. This setup is much more efficient than anything you can buy in the store.
Combine this with the previously mentioned snowball lights and you have the coolest Christmas tree ever.
Tiny Arduino powered Christmas tree

The Arduino Christmas tree doesn’t have to be a huge space pig. This amazing little mini Christmas tree by Instructables user Imperkins is built using LEDs and copper wire. It will fit even in the smallest apartment and will be a great decoration for the Christmas table.
If you have the few hours it takes to assemble it, this is a great little project to put your soldering skills to good use. in the test and learn how to drive many LEDs with a limited number of I/O channels.
