Advice for building a wireless temperature sensor as small as possible?

2022.01.19 16:43 Surveyor7 Advice for building a wireless temperature sensor as small as possible?

I would like to be able to integrate sensors (or PWM signal) into a mini wireless package, however my technical background is not ECE/IoT...
I thought a temperature sensor, like shown in this video (link), would be the simplest starting point. My main goal would be to scale things down as small as possible (e.g. 2x1cm). I only need operation for something like 24-36 hours and I have a few hundred bucks I can spend on redundant components, trying multiple things out, etc. The less code the better.
Thank you in advance! I'm grateful for any help I can get.
Some microcontroller boards I was looking at...
CC2541 (existing dev kits available)

2022.01.19 16:43 effing-boomer LE: Switching to MAGIC on Menu causes CTD every time

I'm running LE through the Steam site. I loaded up several mods from the Workshop. I also loaded up a bunch of Nexus mods manually.
The only real Magic mod I've loaded is Apocalypse. I have been playing almost problem free. The ONLY problem has been selecting the Magic menu. As soon as i do, I get an immediate CTD.
I'm okay...kinda... playing without Spells (kind of different, actually), but I'd like to figure out what might be causing this.
Ideas?

2022.01.19 16:43 Packeselt How often should I update my frontend changes -> backend for user's inputting new data?

Hello folks. I'm building a little hobby budget app, and am a lot of the backend with AWS. (DynamoDB and graphQL).
It's more of a concern for down the line, but I got to thinking, do I want to update my data fields everytime the instant a user changes them (say, changes the amount for a budget for a certain category), or do I want to wait about once a minute, and then do an overall data check? Simply to cut costs on the serverless setup.

2022.01.19 16:43 SheldonBrown24 CEOs Deserve Their High Pay

It sucks that some people work their asses off and barely make ends meet, but I feel CEOs are unjustly crucified for making so much money. They work super hard, crazy hours, and have a ton of stress. Each time there is a jump in responsibility, there SHOULD be a pay jump. Why else would anyone want to take the job?
Anecdotal example: Cook at McDonalds makes 40k a year. Assistant manager makes 55k. Manager Makes 80k. Franchise owner makes 120k. District area manger makes 180k. State manager makes 240k. US district area manager makes 300k. Keep this going until you get to the CEO who makes millions. As responsibility levels up, so should the pay. Otherwise, nobody would ever want to take the high level job and the stress/responsibility that goes with it.

Hey everyone, is there any hypnos that increase your musculinity, drive you to success and make you smarter? (The opposite of bambi and all the sissy hypnos) I'm a bisexual guy who discover his femininity and musculinity and want to enjoy my both sides :) Btw I don't use sissy hypnos at all, I'm all natural.
