Having no experience of electrical circuits I was unsure what to do when this arrived. The download instructions aren't that clear so here are my tips for assembling the multi colour LED version with white LEDs: View a PDF with assembly details here (Credit to the reviewer pages back who posted this): http://www.haoyuelectronics.com/Attachment/CTR-30C/CTR-30C%20Flashing%20Christmas%20Tree%20Instruction.pdf Link with images is: http://www.haoyuelectronics.com/Attachment/CTR-30C/ CTR-30A is one tree PCB CTR-30B is the other one CTR-30C is the base Resistors: These can be fitted in either direction and are: 6 x 1k: Colour bands Gold/Red/Black/Brown 6 x 10k: Colour Bands Gold/Orange/Black/Brown 1 x 2.2k: Colour Band Gold/Red/Red/Red Locate where these go via the pdf and insert in to the relevant location R1, R2 etc... The single 2.2k goes on R7 on CTR-30A. Transistor (With the 3 legs) Must be fitted the right way but the PCB shows the orientation. All are the same spec so use any of them. Capacitor Must be fitted the right way. Longer leg is (+) Positive. And negative side is printed on the casing. All the same spec so fit where required. LEDs Must be fitted the right way. Longer leg is (+). Positive terminal is the lower location where the letter is such as D1, D2 etc. Solder in place with enough length to bend to point out the way. Solder the tree segments together. When you fit the soldered tree to the base I recommend installing and power up to test before soldering in as you can have a (+) against a (+) as per the instructions but it can still be 90 degrees out. I did this and it was a pain to unsolder as I didn't have a solder sucker. It all went together and worked great once I had realigned the tree to the base and works great off USB power.
