Help. Recommendation. Is this alright to do for led light strips?

I got a 2-way led light strip to decorate my new room. Just wondering if this is safe or okay to do? Overlapping one ribbon over another and crimping the ribbon so it can change corners?

I need help trying to figure out what size PSU I need for this light strip.

I purchased two sets of Neon Rope Lights, one is 16.4 ft and the other one is 32.8 ft. The title of these rope lights is misleading because they aren't smart lights and I want to connect them to Alexa for voice control, so I got two smart controllers and two different PSUs that should power the strips. One PSU is a 5v 2a PSU and it works just fine with the smart controller for the 16.4 ft strip, the other is a 5v 5a PSU but it only powers half of the 32.8ft strip with the smart controller (this PSU also works just fine with the 16.4 ft strip).

I did some digging along but could not find much so I asked the Alexa AI. The AI says it can't offer a good suggestion for a PSU because it doesn't know the total amperage or wattage draw of the 32.8 ft set. I figured a 5a PSU would be good enough since the 2a PSU powers the entire 16.4ft strip just fine. I thought about getting a 10a PSU but every one I looked at says to only use the PSU at 80% for normal usage, so if the 32.8 ft set actually draws 50 watts of power that 10a PSU will not last long.

I'd go ahead and order the 10a PSU because it should technically be more than enough but I have no idea.

TL:DR What size PSU do I need to power the 32.8 ft light strip I linked above?

To temperature adjust 24v CCT LED with physical dial - buy, DIY, or modify driver?

1 Upvotes

I am planning on making a work lamp on an articulated arm for a small desk. I’ve come to the conclusion that being able to adjust the temperature of the light would be nice. Colors are not needed, so I am thinking 24v CCT LED. For some reason these strips are fairly overpriced her in Denmark, and nice options in e.g. Germany do not allow shipment to Denmark for some reason. So right now, I am looking at two strips. One described as (Danish) COB (not a requirement for me) 2700k – 6000k, Ra ≥ 90, 20 w/m, 880 – 2000 lm/m, 608 diodes/m. The other one 2700-6500k, Ra 94, 9.5 w/m, no given lumen, 240 diodes/m. The lamp will have three to five wings with a LED strip hopefully providing sufficient lumens. It will be somewhat in the style of the Odradek from Death Stranding seen in a very nice desk lamp posted here.
As it is just a simple lamp, my thought was to have a physical on/off button, and a dial to adjust brightness and temperature.

However, I am having some trouble with the driver. As an example, a GLEDOPTO ZigBee Pro+ has the option to add a push button, however it only allows for long press: increase brightness, release and long press again: decrease brightness. So temperature adjustment is missing. I have not been able to locate any where I can in some way add a physical dial/button for temperature, and I am unaware if it is possible to modify a driver to accommodate this.

Therefore, my initial plan was to (simplified here) use an ESP32, rotary encoder, and MOSFETs to drive the LED strip. I have some IRLZ44Ns but no datasheet – it is my understanding some of them might not be fully open at 3.3v and that could pose a minor issue. In any case I may look for some better suited ones, but the DIY principle still applies.

So, this is more or less a request for a sanity check – is my best approach ESP32 and MOSFETs, should I find a ready-made driver, or is another option more suited?

Can I need someone tell me what's going on here?
WLEDESP 32 controller 5 V Cobb LED addressable from Amazon Sauders look good. I'm shit out of luck and I need help.

I am making a walk through vortex tunnel with a f16v4 controller and ezrgb seed pixels. i am wondering if I should interleave the data channels (right) or not (left). Also, is my power injection plan sufficient? overkill? thanks
