Nice! I just put eight meters of dotstars in my tree, but that's only 480 rgb LEDs. And indoors :-) Did you consider DC/DC regulators for stabilizing 12V? 10A

Did you consider DC/DC regulators for stabilizing 12V? 10A per bus could be done with inexpensive boards?
- chrlilje 11y agoThat was a mistake by me in the design process - I simply forgot, that the charge voltage of battery systems are 14.7 V - And when I tested the diodes, they were not very happy getting more than 13 V. We should have gotten a stack of cheap DC-DC converters to keep the voltage at 12 V for each strand of Diodes. But we realized the mistake too late for another Aliexpress-order, so we just had to go with a solution with parts from our stock. ..next year we will have lots of better ways to do things.
