Do it yourself LED Christmas Tree from $3.37

In the old days you used to drive far, far out, on a snowy day and after a long hike you fell a pine tree to decorate it at home and enjoy it throughout the winter. But that’s not up to date anymore, decent Nerdchristmas is only possible with this DIY-Set LED Christmas Tree.

• LED Christmas Tree
  • at AliExpress from $3.37 | Banggood for $4.07

This set not only combines chic PCBs with a Christmas atmosphere, but also radiates a certain geek coolness. Maybe you should have some experience with the soldering iron and the principle of direct current and alternating current, but it is also a nice gadget for beginners – and an ambitious goal. Banggood has also compiled a guide – Instruction for Christmastree – which is quite understandable, but will be incomprehensible to an absolute layman.

The tree consists of three printed circuit boards, which can be put together to a Christmas tree form, everything is already pre-etched and one must solder only the resistors, transistors, LEDs etc. at appropriate place. You can choose between a variant with 3 different coloured LEDs or a variant with multicoloured LEDs.

Once you’ve put it together, you can power the Christmas tree with a USB cable or batteries. The battery compartment is also included in the set, the 3 AA batteries unfortunately not. In total your LED tree is 60 x 136 x 60mm and unfolds a nice play of colours:
