Everyone always complains about the Christmas season coming earlier and earlier, but we think when we can have Christmas trees like the one pictured above, it’s not such a bad thing. Created by English fashion designer [Gareth Pugh], the tree features sixty white neon tubes, and is supported by a freestanding metal rod. It reminds us of the light sabers in Star Wars, which is probably why we like it so much. The tree is just a carrier for the decorations anyway, right? You can check out the tree in person at the TOPSHOP in Oxford Circus, London.

High Power LED Blinking Circuit

Evil Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put a LED in series with a small blinking incandescent bulb from a string of Christmas lights. The bulb has an internal bimetallic strip that bends out of shape when it heats up, cutting the circuit. when it cools enough, it returns to its original shape and closes the circuit again, making the bulb and the LED turn on. Both lights have short period of sustained light when they are initially powered up since the bimetallic strip is still warming up.

The project uses a 5W blue LED, the aforementioned bulb, and a 6V battery pack loaded with 3 AAA batteries. The battery pack and the lights are all attached to a small section of perforated board. Duplicating this project should be easy and provide a very bright LED, but to make a 5W LED shine its brightest, a larger bulb and a heatsink will be necessary.
