For this initial board I used the WS2812 chips out of the package… For the other 11 boards I may try baking them at 60C for 6 to 12 hours before soldering to reduce the potential for issues that Doug has experienced (though my stuff is for fun not production) PSA: WS2812B LEDs may not be what you think they are!
Thanks for the write up - where did you get your leds from? I have a batch from Aliexpress that don’t work too well - I’ve resorted to pulling them from known working strips.
The packages also seem to be abs, not very heat tolerant.
@Jarrett sold me the led modules with the strips…
I think he has a bunch of em (roll of 1000 mebbe)…
I ended up soldering all 12 strips (60 leds) in the oven…
Was going to bake some first(12 hours @ 60) to ensure they were dry enough but got impatient and reflowed all of them…
These strips are awesome @Majicj, @xquared, and I built them this afternoon. We used the oven. Then we tested them on @lukecyca’s party cat. Good times.
