    Replying to my own thread. I believe this is not safe and will result in damage to module if a voltage divider or level shifter is not used.

    A best solution is to power the ESP module independently of the programmer and just use the programmer for the 'data' connection.

    Stay tuned, I have developed a board to do this and just need to solder it up and test it.

    Anyone ever seen this? I have no idea why this is happening.

    That's usually caused because not all the web page data was received by the broswer (probably style sheet info). Anyway, the only time I've seen that is if the PixelStick is busy processing E1.31 data at the same time that you are browsing the setup pages. I suspect it's a limitation of processing all the traffic. Try turning off your E1.31 data source and try accessing the device again.

    I would love to try building some of the PixelPops, are there any more of the boards available? if not, I'll get on OSH Park and order some.

    Thank You,

    Dave

    2016 - 184 channels of Blinking/Flashing using 4 Arduino MEGAs and cheap home-made props.

    The 3.3 volt regulator LD1117v33 gets really hot when doing 12volt pixels. Is there a fix for this?

    The only 'fix' is to help it dissipate the heat.
    When feeding it 12V that regulator has to dissapate a lot of excess watts of heat by the extra ~9V * your amp draw of power.
    I'd put a heat sink on it to help out. They are cheap and readily available.
    go to Tayda Electronics and search for: HEATSINK TO-220
    Or you can get these from Amazon PRIME: https://www.amazon.com/uxcell-21x15x...5%3A2470955011
    You should also use some heat transfer tape/paste when mounting it.
    You do NOT need any special bolt and screw to mount these. Anything that fits the holes will do.

    Are you running your pixel power through the ESPixel or just using the controller for data transfer?
    If only using it for data transfer, you could also put a buck/step down voltage regulator in front of the pixel controller and drop the voltage to 5V before you feed it into the ESPixel.

    I am connecting 12 volts to the ESPixel terminals. I will look into some buck/step down voltage regulators.
    thank you
