3D LED Christmas Tree

Back to overview

DIY solder kit. The flashing Christmas tree kit consists of three circuit boards, 37 LEDs that alternate flashing, and dual power sources.

@Mathijs Groothuis: The other board is being populated jut the same as the first one. The resistors are not exactly at the same place but are numbered the same. R7 is only on the first board. The LEDs are also in the same order.
BTW: I came across pictures on Aliexpress that were mirrored left to right.

I see many trees with a whole different led order for the other tree half. On this page I only see the first half. All other trees on the internet have different order. Can you elaborate on this one? My green was too dim, so I changed it to your order, but I don't really understand what's the correct order when you take in account that certain resistors are meant for a certain color.

Thank you for taking the time to post this. The little trees are a nice Xmas project and they do not come with instructions these days. There are dozens of vendors happy to take your money mind you.:-) I got a very Chinese version of the  BOM  but this is so much better. Bless you  mate :-) I chnaged the current limiting resisitor all to 330 and the green are all still too dim for my tastes. I did not place the led's per instructions either :P
