Don’t you have enough to do this Christmas without having to worry about Christmas cards? The answer is yes. So build a LEGO machine that will handle all of your holiday card needs. That is what this Mindstorms assistant does.
This machine churns out Christmas cards like an elf churns out toys. It was designed and built by 14-year-old Sanjay Seshan and his 12-year-old brother Arvind. It’s called the Holiday Card PLOTT3R and it can print multiple designs including a festive tree and a snowflake, which is pretty much required on Christmas cards. It will even sign Santa’s name for you.
You still have to mail your cards out, but at least it does the rest. And you got to play with LEGO blocks. So it’s a win win. It would be a fun project for the holiday. While they didn’t provide build details for this specific machine, there are instructions for creating a non-holiday version, called the PIX3L PLOTT3R over on the Seshan brothers’ website.
