Project: Water Cooling Turbine

[rendermandan]

Thanks Spawn, +Rep you just saved me a boat load of money!!! I ordered 15 blue leds and resistors. I'll skip the idea about color changing for now. and I'm not sure I'll use all 15, I just figured I'd get some extras while I was placing the order. Thanks again.

i would look more into the colour changing thing bcoz that would be rele cool.
im pretty sure you could do it with a thermistor and just have an extra resistor on 1 colour.
there must be someone here that would know how to do it

I would need someway to measure the temp of the water also. Preferable measure it right after it leaves the cpu block.

np. so you got 15 eh, thats good then you get the 1 free 5mm Blue LED. they even through them in coloured bags so you know what colour right off the bat.

you could get this and make a T line right from the cpu (in or out). you would need some kind of micro controller (i think is what you want but not sure) and have it change the number/colour of led's on at one time.

on a side note what program did you use at the start of this log to make rendering (right word?) of this project. i started making a sketchup to show what i was going to suggest. so now i'm just building it for fun.

Thanks again for the head up on that company, and they only charge $2 for shipping. Excellent!
I've been doing all the 3d modeling in Autodesk Architecture 2008

any pics?

none at the moment its going into my case mod that i have delayed whilst i play around with a couple of ideas. (possible involving a complete rebuild as there isnt enough room in the two cases)

for the idea with the color changing leds.. this is an NTC right, so ntcs are like:
temp up, res down use a switcher relay, if the water is cold the relay is not forced (dunno how it called but its "off") because the resisor is 2 high = blue led is connectes in circuit. secound circuit on relay activates when the water is getting warmer, the resistance(?) is sinking and the relay can switch to the blue led.. bad thing on this is you just know that the water is hot or cold. not how and youll hear the click of the relay... im looking for a IC circuit somewhen and try to translate it

[rendermandan]

wow, that would be great!

[FrooP]

first off i want to know if you think you can solder something like this.. its the basic version, fades a bicolor led from 1.2 to 12V, we would manage that with a ntc and some stuff more.

[rendermandan]

Yeah, I think I could solder something like that. as long as it was clearly labled out where things go in the breadboard and what needed to be soldered to what. +rep for your help!
