Here’s another DIY hack project that I find might be really useful. Everybody likes fireworks and around here people just look for a reason to set some off, legal or otherwise. It can be dangerous though and First Responders are usually kept pretty busy running to scenes where people have gotten burned or worse. This DIY LEGO project solves that problem for you and allows your family to enjoy the spectacle of home launched (or home made) fireworks without the fear of one losing a hand.

This autonomous NXT robot will light multiple fireworks in a sequence. It uses a MINDSTORMS NXT, two light sensors (one for navigation and other to detect a lighted fuse) and an Ultrasonic detector (to adjust the torch arm height depending on the height of the fireworks fuse wire. It uses three motors - two for motion and and the third for the torch arm elevator.

How cool is that? It doesn’t replace the prospect of you burning your house to the ground but it could save your wife from having to open your ketchup bottles for you.
