64x96 SmartMatrix outfit

Well, that was months of work. Huge thanks to Louis for the work with his driver and animatedgifs that I heavily depended on.
Finally finished a page with more build info and the up to date code that runs on it: https://github.com/marcmerlin/NeoMatrix-FastLED-IR

I see from this post you’re using a BEC to convert the battery output to 5V for the panels, which one are you using? I tried using some “3A” BECs, and found they couldn’t even do 1.5A continuous and were extremely hot. Do you add any capacitors or anything extra besides Lipos -> BEC -> Panels?

I use this, it does 10A fine: https://www.amazon.com/EPBOWPT-Converter-Regulator-Supply-Transformer/dp/B01M03288J/ref=sr_1_1?dchild=1&keywords=tobsun&qid=1599773789&sr=8-1

I do not use capacitors or anything else. It also peaks in a nice way where it will stop at 10A but will not drop voltage. This means that if I make my panels too bright, they won’t get full brightness but the MCU doesn’t reboot from undervoltage either (that said, maybe the ESP32 is resilient and once I switch to rPi, it’ll be a different ballgame).
