Nice project! :) I was wondering about heat. These strips are often put in aluminium rail for heat dissipation. Are you finding that the light runs nicely? No warping of the 3D printed parts due to heat?
So far, I haven’t had any issues yet, using it an hour here and there. But I feel like it will warp being PLA. I plan to make the next version PETG which will do better with the heat.
Hey bro! Wanna ask, isn't this electronic design overly complicated for the end result you want? Correct me if I'm wrong but the Arduino is uneccessary as the LED strips do not need PWM signal to work right? Dimming of the LED strips could have been accomplished by reducing the voltage that is fed into the 12V strips, by correctly hooking up the potentiometer as a Voltage Divider. Doing so not only simplifies stuff but also, reduces the cost of the project. Just my thought :) Not sure if I'm correct in practice but do let me know! Cheers~ Something similar to this "3-Channel"Analog Dimmer Project: ruclips.net/video/bJKLvEuFiiA/видео.html Yours would be a "1-Channel" Additional example, ruclips.net/video/jdwlqoHAA1o/видео.html
Reducing the voltage won’t dim the LED’s. But it’s true, like I mentioned in the video, it’s more than necessary to create a dimmer circuit but I’d argue that it’s not complicated and way easier to employ an arduino than to wire up, say a 555 timer circuit. To drive these LED’s it has to see 12v to properly turn on, so some kind of PWM signal is required. I mentioned all of this in the video.
A single MOSFET and a cheap microcontroller is definitely the most accessible way to have this setup work. Exactly how I would achieve the dimming functionality. Nice project! (Also for the original commenter, these LEDs are probably constant voltage meaning they could be dimmed by an adjustable constant current supply but that is quite a lot more complicated and totally unnecessary).

Very cool project, but what knife is that, it looks really nice??
