In case you missed them the first time, here are our most popular posts from the past week.
Our most popular post of the week was about a ball that has a matrix of 256 LEDs encrusted onto its surface, allowing all sorts of patterns to be displayed.
Next up is a post about the vibrator shield for the Arduino. If you must mix sex and nerdy things, this is one route to happiness. This post is safe for work but the links may not be.
After that we had a post about a novel way to take panoramic pictures. In this post, you will see a ball that has an array of 36 cameras embedded into it. If you throw it into the air, it will take a picture at the apex of its travel.
In fourth place, we have a post describing how you can add an external GPU to your laptop. If you only have a laptop and are looking to play with the latest and greatest graphics, this is one route that you could take.
Finally, if you like things that glow, this one is for you. This post links to a video showing you how to make luminol using household chemicals.
