The updated HexLED Lights are posted on Thingiverse. They were updated to work with a with a higher current switch and higher current DC jack. As noted in the thing's description though, it is still a make it at your own risk deal, since the switch I had is not DC rated (it is an AC 250V/6A 125V/10A" switch). If anyone has a better switch please let me know and I if I can get one (that is it is available and not very expen$ive), I will see if it will fit. I'm not electronics expert, but I have been using the LED panels without an issue intermittently over the past couple weeks, having them on, cycling through colors, for around 8-10hours at a time, though I don't run these all the time (too wasteful). I am running mine using a 5V DC / 4A power supply so that is about as high as my panels will go when the LEDs are on white which I never use. In actual use though it runs a bit over 2A (when all LEDs are on white it draws the max current). In any case it's uploaded. I have had it hanging on my wall and it seems to work well, and I'm not planning any further updates at this time.
Welcome to my Stoopid corner of teh Internet. It's mostly gonna be 3D printing stuff, but I also post some recipes, projects, and the occasional rant here as well. More Stoopid stuff is updated regularly.
