I want a thermometer with dual sensor probes, one for outdoors, one for indoors. When either temperature passes the other, I want it to beep at me or an equivalent alert of some sort, so I know to get up and close/open the window.
Someone invent one and send it to me. Thanks.
-
They already have those, just without the beeping. So half the work is already done.
-
*has one beside him*
-
The beeping would get very annoying after a while IMHO. Just get one with a really big display that you can see from across the room.
-
and when the temperatures reach equilibrium... BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEP!
-
Ok, where would one go to purchase such a thing?
-
Umm....
Can't you just open the window when it's too hot, and close it when it's too cold?
I could build you one rather easily, but the costs would be prohibitive (unless you're filthy rich, in which case get back to me ;)). All you need is a couple of digital thermometers and a diff-amp circuit...

It's actually for summer, so I'd be opening it in the evenings and closing it in the mornings. But the whole point of this would be to have something that would tell me when it got cooler outside than inside (so I'd go open the window), or hotter outside than inside (so I'd go close the window).

Ahh...
I could do you a basic schematic if you want, but you'd have to build it and tweak it yerself...
-
buy an air conditioner and keep the window closed at all times :p

Heh, no, that's ok. I guess I was kinda hoping that someone would link to just such a product on Amazon or Home Depot or wherever that I could buy. It didn't for a moment cross my mind that you HLPers are actually crazy and talented enough to be able to invent such a thing! :yes:
-
shouldn't be to hard to drawn such schematic indeed:)
Fun to do also:)
-
I try. :D 'tis fairly simple electronics (me having just finished my A-level in the same, I still remember most of it) - if you know any army techs or electrical engineers then they'd almost certainly be able to hook you up with something. :) I mostly make guitar effects circuits, but this kind of thing can be fun as well.
-
Never underestimate the craziness and talent of an HLPer!
(or at least the craziness):nervous:
-
Lazy bugger.
-
Do we get adminship if we invent a wheel-and-pulley system that will open/close the windows as appropriate for you?
-
Yes, but they have to be the kind that need zero installation, work with any and all windows in the house - wirelessly, mind you - and don't squeak. Oh, and I'm not posting floorplans or any other schematics.
And neither is Splinter. :p

i think there's a few wireless versions about, too.

Lets just make it automatic :D
