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 - π€
(/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.
