<p>Michelle, your perspective is really interesting.<br>
</p>
<p><br>
</p>
<p>For me, it's about the creative process, and learning about technology. With a bunch of parts and wires, I made a weather station that shows temperature, relative humidity and barometric pressure. Learning how to make the pixels on a screen go a certain
way, writing the program to capture the data and save it or send it somewhere, connecting wires to make something happen. Knowing you did it all yourself. I don't think it's any different than any other creative endeavour. We do it because we find it fun.
Why does a chef cook? I don't understand how that can be fun but we all have different things that float our boats.</p>
<p><br>
</p>
<p>Happy Friday :)</p>

<div dir="ltr">Can someone help me out here. Maybe it is not as interesting as I thought. Basically, I learned how to deep sleep a battery powered ESP32. The turkey was unimportant. A very portable device that reports humidity (a cause of mold, for instance,
or of hugely expensive water leaks in a condo) and temperature (for cooking, etc) should be in everybody's house, IMHO. The turkey stuffed with micros was a bit of a joke.
<div><br>
</div>
<div>Deid, I like the bead thermistor more than DS18B20s because, waterproofed, I can insert it deep into the turkey breast, for just the right safe temperature without overcooking. Besides, I've got 40 thermistors left <haha>. They worked fine when powered
by 3.3v and not a GPIO pin. I suppose I could spare 0.15ma (3v / 20k ohm) continuous drain on the 2600 ma-hour battery. </div>

<div dir="ltr">A couple of corrections... multiplying a minute of microseconds requires the microseconds to be declared as 60000000ULL yes, thats ULL at the end, Unsigned Long Long. I found this error when I went above 20 minutes sleep.
<div>Also , concatenation of strings in php is with the period, not the plus sign. I should put all this on github so that my corrections are available.</div>

<div>Michelle, I am defrosting a turkey slowly inside a closed ice chest on my balcony. I have a temperature sensor on the turkey that warns me when it has risen to 3 degrees Celsius, meaning it is thawed and time to cook it. I'm not heating it in the ice
chest... ambient daytime warmth just seeps in slowly through the walls of the ice chest to melt the turkey slowly. The turkey is cooking in the kitchen now.</div>
