I was gifted a Tall Trees LED Co Harvester bar, "205W from the wall." I wasn't convinced a bar light was really well suited for this build and I wanted it to fit a 2x2 space so a little hacksaw time gave me this: PXL_20220715_040316406.jpg Its' voltage and current needs are matched by my currently i...

Not quite there yet, life's intruding. Got all the parts, just need to sit down, cobble the parts together, and bang out some code.

Should I start an instagram or something?

Yes, they are all in parallel in the left picture.

Tip: put two 280mm strips in series first, then parallel the pairs. This will bump up the voltage to ~40V so use a -42 driver. This will reduce the amount of wiring and reduce the voltage loss over small wires.

Yes, you can double them up. Two of the 280mm strips in parallel is equivalent to one 560mm strip.

An esp8266 can only output up to 3.3V on its gpio output. Without any additional hardware to raise that pwm signal to 10V, you will only get about the lower third output capacity of the driver.

I'd recommend browsing the entire archive of Home Power magazine, https://www.homepower.com/

Wire to the strips should be series or parallel?

How they should be wired depends on how they're wired now, can you identify that?

Someone has this interesting thread on how to protect these sensors , as they don't exactly have the best long-term durability.

Chopped! I gave up on canopy management of the left side, didn't get around to installing a second layer of netting and it just went chaotic.
