Busy weekend, wow, barely had time to touch this.

Here's some of the info for people that want to play along at home:

https://www.adafruit.com/product/2796

So the basis is this adafruit feather adalogger. Out of all the flavors of arduino, i picked this one because i liked the built in SD support and the form factor matches up to a good little screen. Also I already had a 3.7v lipo battery to run it, its got native USB and quite frankly i just thought the name was clever, haha. Also its an ARM m0 chip instead of the 32u4 so its faster and has more ram and all that fun stuff.

I mated it to this screen also from Adafruit. I took a guess at it, but it actually worked out perfect for displaying 3 lines of temp. The way the characters and formating and all that worked, it was better to do 3 horizontal lines, easier to read, but i would like to eventually code some kind of bar graph or something fancy.

As an added bonus, its got a 'stemma qt' port which is just a nice lil plug and play i2c interface, i could add networked sensors or all kinds of other weird stuff later.

These are the thermistors i'm using. They are 100k NTC thermistors known as '3950' because they have a beta coefficient of 3950. Lots of 3d printers use them, they can handle up to 300C (theoretically) and they have the largest change in resistance which is good for resolution.

oh what else, i also have a 3.7v 100ma lipo from adafruit. The feather has a built in charging circuit which is flippin' rad... eventually i can use my onboard usb charger to charge it, but i probably will get quite a few hours runtime out of this as it is.
