    Heatermeter on new small-footprint platform: HLK-RM04 (RT5350 based)

    Help me understand why this is good? Cheaper than rpi? Smaller physical size?

    HeaterMeter project / tindie on hold

    I'm really sorry, Bryan. Reach out for help when you need it, there are a lot of us here who would love to help any way we can. Business decisions, staffing, technical issues, or anything I bet someone can help.

    Running HM off of a battery (a review)

    Right. W-h would be a better common unit for talking about battery size.

    Running HM off of a battery (a review)

    The battery doesn't need to be that big physically. For example, iPhone batteries are 1850-2250 mAh so you could get away with 3000-4000 mAh with something double the size of the iPhone battery. Just look for LiPo (Lithium Polymer) batteries on ebay, one thing you might need is a circuit to step...

    Serial Checksum Errors

    Glad to know there's nothing to worry about. Thanks Bryan.

    Default PID Settings

    That all makes good sense, Bryan. I've also observed the I increase over time to dominate a stable system at temp so I guess all is working as it should. Thanks for taking the time to explain.

    Default PID Settings

    Why the change, Brian? Especially interested in the move to B = 0, but interested in the increase in P and I as well. Thanks.

    Trouble hitting and maintaining 400F with blower

    Updated the graph in Post #8 to the right one so you can see what I'm talking about.

    Wish list...

    Here's another vote for a countdown timer that can trigger alarms.

    Trouble hitting and maintaining 400F with blower

    It does have a gravity flap. I tried it right side up and upside down. Upside down keeps the flap out of the way and in either case the temp wouldn't go above 300.

    Trouble hitting and maintaining 400F with blower

    Ralph, the roto damper with stock fan performs just fine, no complaints. It's the Auber 6.5cfm blower that won't go above 300f.

    Trouble hitting and maintaining 400F with blower

    Experiment with the Auber was before messing with PID, maybe I posted the wrong graph, sorry, but 100% is 100%, right? And the Auber wasn't cutting it, at least on my setup.
