    Can anyone help with PID adjustment?

    I am running a 22" weber Kettle (performer) with a microdamper and I don't know where to start with the PID adjustments. Current Settings, P=4 I=0.02 D=5 Fan output voltage on above 0% min 0% max 50% startup max 50% As of right now, I get crazy temp swings. I think I have 2 issues 1. Gap...

    I found that I had a slowly dropping voltage on the Mos pin on the button board. Ironically it's the same pin that gave me trouble on the base board for my previous problem. Voltage there started at 2.85 slowly dropped down to about 2.6 and that's when the LCD started to act weird. Took it all...

    There is something else going on now. After 5-10 minutes of being powered on, the backlight starts flickering. Up until that point it works fine and continues to look as though there are no other issues according to the web interface. Eventually the screen goes blank and then displays random...

    Bryan, to clarify, it looks like the trace was connected to the solder pad on that pin hole from the factory. Not a big deal to me since it was an easy enough fix that I didn't have to scrap the board and start over.

    Yeah it seems like it was connected between 6:00 to 9:00 if you look at it like a clock. I dug it out until I was comfortable with it and there's no short anymore. After that it booted fine so I switched over to 12v and threw it all in the case. Seems good now but I haven't hooked up any probes...

    Found it!! Thankfully, I didn't need to de-solder anything. just picked at it with a thumbtack until broke the connection.

    Hi Bryan, Yes it is a short. I also checked without the chip last night and there is still continuity to GND. I pulled the plastic housing off the LCD riser to check under that but it looks fine. I'm wondering if its under the chip socket or inside the pi header. Either way, I'm not looking...

    I measured and confirmed that I do have 5 and 3.3 at those locations. So far I can tell that MOS is 0v and should be 3.3v (like I mentioned earlier, there seems to be a short to ground somewhere.) Also, AREF on the Atmega is 0v. According to the voltage diagram on the wiki, this should also...

    Don't mind the jumpers from the cap to the mosfet...I had some trouble with a trace coming up when removing a capacitor that I placed in the wrong location.

    Hello everyone, I've just built a 4.3.3 and I cant seem to get it working on the Pi's 5v.(I have not tried the 12v supply yet) When I hook up the Pi3, I can get to the webpage but I see a No Communication error for the linkmeter. It fails with the following info in the system log Thu Sep 29...
