Photoresistors are very common electronic components that works like a normal resistor in total darkness, but as soon as light is hitting it, it changes. Increase the amount of light and the change will increase as well. This phenomenon is commonly used to detect when a light beam is broken, turning them into a light controlled switch. But did you know that they can also be used to make music? In this video Make: magazine walks us through a simple build that results in an electronic slide-whistle! Basically you transform light into music, and if you don’t think that is a cool idea, then what is?!
If you are here, you have probably seen our cool introductory video of the new Barrii mascot and want to know how it was done and how to make one for yourself! You can download all the necessary files by clicking here and start designing a personalized mascot right away.
The video above will take you through the assembling process, and the video below will show how our particular design was made. You are welcome to copy and imitate, or create a unique mascot just for you. You can even change the 3D models into something completely different if you like! We would love to see a video of your mascot when you are done!

As promised, here comes the second tutorial for polymer clay beginners, care of PuddingFishCakes! In this tutorial Helga walk us through the various kinds of tools and material that can make your clay modeling life super easy. Polymer clay is in general an excellent material and in our humble opinion, something that no crafter should be without. So if you’ve never used it before, sit back, learn, and enjoy easier crafting in the future!
You can see the first part of Helga’s beginners tutorial here.
“Smart materials” such as memory metals are really fascinating, and their full potential is far from known. In this video, Associate Professor of Mechanical Engineering & Materials Science at Yale Dr. Ainissa Ramirez shows us how memory metals change phase and shapes with heat, and why this is so useful for robotics such as the Mars Rover and even in medicine. A must watch for anyone interested in making robots or health related inventions.
