Anyone know much about electronics?
I have an NTC probe that reads 9K @ 0C and I want to add a mechanical offset as the controller does not have this functionality.
If I throw a 32K resistance in parallel I should get my +5C offset at 0C which is perfect.
BUT… I’m feeling a little greedy and I’d like to trim it a little each way, and I reckon between 25K and 50K would be a perfect amount. If I throw a 50K potentiometer in there, it’s variable between 0 and 50,000 which is not ideal. Is there such a thing as a potentiometer or similar that provides between 25K and 50K resistance?
Never mind, I’m a dickhead… I can just stack a fixed resistor and a potentiometer in series
LOL This dude didn’t even know you have to stack the fixed resistors and pontomoters in series… What am idiot - 🤓
(/s in case it wasn’t obvious. I genuinely have no clue what this means, but I couldn’t miss the chance to make a good joke)
Hump day, and the nice cooler nights have eased :( didn’t even get to bust out the thicc blankie yet!
I was starting to think I might need to invest in an electric blanket! Body heat seems to do an alright job at heating the bed up, however the initial plunge into bed is quite cool.
Do it. A pre warmed bed is bliss. I sleep hot but takes a while to get toasty without the blanket.
I love the initial dive in to a cold bed. Then you create your warm little cacoon and get all snug and its so nice to sleep in. And then the alarm goes off and its work again :(
Yeah, that’s the best part of winter (the warm cocoon part 😁, not the alarm and work part 😢)
