LED Thermometer?

The Tick · 09-05-2002, 04:39 PM

I've looked high and low and have yet to find one of these. What I'm looking for is a thermometer with these stipulations:

-hardware only, no MBM stuff
-compunurse style, fits behind 5.25 drive cover with the real thin thermistor
-the kicker, LED (not LCD!!!) display. I want to be able to see this thing at night.

I want to use this to monitor my cpu so thin is needed, and I would like to mount it on a 5.25" drive cover. The closest things i've found so far are the lian-li T-3's and antecs hdd cooler .

I'd like a prefab one but at this point i'll settle for schematics. anyone?

Hum... these LED displays are getting rare (read: probably out of fashion!)

I'd need a compunurse to mod it with an LED display, unless someone has schematics for the compunurse, or at least specs for the probes.

fashion, schmashion...im goin for practicality

compunurses are nice but i cant see them when my puter is on the floor. i dont think you can rip the LCD off the compunurse and stick an LED display on there because of much different connection types...right?

No, definitely not. A new circuit would have to be built.

nice, pH is on the ball...those first two links are the same unit, ive seen that one already but havent been able to figure out what kind of input voltage it needs (much less where it goes). also, how big is the thermistor on that unit? big enough to not fit under a cpu?

the schematics in the other link dont look too bad but i doubt i could get that to fit behind a drive cover. also that takes in 220V so my american 115V volts wouldnt be good for that. im sure using other transformers and other parts would fix that, but thats beyond my knowledge of circuitry...

The Tick · 09-05-2002, 08:59 PM

ah, first line of the UK127's specs...5 V...sounds handy...what about the thermistor though, can it be replaced?

pHaestus · 09-05-2002, 09:08 PM

It uses an LM35 (transistor); dunno where you'd find a small enough one for mounting on side of CPU. If using a TBird or other ceramic chip you could just epoxy under the center of core (thread the wires through socket).

im usin a watercooled p4...

hmm, dunno what the price of one of these is, but maybe get the Lian Li or Antec one with the LED and mod it/extend the thermistor so it reads your CPU?

that was my next course of action if a modular couldnt be found...i've been lookin at the antec one, that has everything i want, switches between 2 temps, small size, small probes, and C/F temps...the problem is getting the led off the bezel. id have to disconnect the fans from the power and such but that doesnt look to be hard...snip snip...fans are not needed for a fanless puter

lotta work for one of these things but itd be worth it, my computer follows the "less is more" philosophy...antec's cooler costs roughly $36USD after shipping and i just got a job here on campus so ill order one soon if nothing turns up...thanks for the help everyone

why not just pick up a normal lcd (2x16) with backlight and pull the CPU temps from MBM to that? No thermistor on the side of the IHS of a P4 will give a reliable reading, and lcds aren't that much more than the Antec:

It is bright in person, and you could always go with a VFD if the normal lcd wont cut it.
