“I bought the pre-soldered version of the tree.
I hadn't realised when I ordered that this had surface mount components on it.
The LEDs are small but bright. The whole kit looks professional.
I've plugged mine into a pi zero and it doesn't balance very well, easily fixed with a blob of bluetack.
if the tree is available next year then I'll likely buy another one”
“The xmas tree is a lot of fun. It delivers the best visual effect if you can place it in front of a mirror, or a shiny black reflective surface to see the lamps in the rear of the tree. I was not happy with the supplied program to with a bit of experimenting I wrote this program. It is not optimized, but it works just great. To change the frequency the lights change, edit the "time.sleep(.075)" value. You can also enhance this a bit more by making the sleep value random! Hope you enjoy.
Happy Holidays

“This beautiful christmas tree stands on my desk in my office. Everybody loves it. I use it with the sample python code, beacause I don't have time now to develop my own code.
Every geek needs one. And it's also a perfect gift for everyone.”
