Last week we built beautiful Christmas tree lights. You can reprogram, and reuse these all year round. But what's cooler than beautiful Christmas tree lights? How about Christmas tree lights that change based on what's happening around the tree? Adding light sensors to your tree lights should take between half an hour and an hour from start to finish.
You may have seen ghost hunters on TV, investigating paranormal activity (or like us, you may have heard it from hiding behind the sofa while the programme's been on). Did you know that you can use your HIDIOT to build the same type of equipment that ghost hunters use to track down bumps in the night? This battery powered halloween project is easy to build within 30 minutes, and is great for kids and adults.
