Temp Gaged by color of fluids...

[Arkamedies]

:) Good Morning All! I hope you slept well. I try not too, it seems such a waste of time.

Anyway, here is my preponderance... I know for a fact that there are fluids out there someplace that actually change color as the temperature changes. What I don't kow is, other than paint, where would one find these fluids?

My reasoning is this... If you ran color changing fluids in your water cooling system, you could tell at a glance, depending on your systems mods, what the approx. temp. was in your water system.

Combine this with a flow indicator and you would have a visually simple system.

Green when cold... Red when hot..... If you are running a server in another room, all you would have to do is walk by and glance in to see that the temp was good or bad, instead of having to go in and look at meters and gauges.

Help finding the stuff? Or comments on why this would be a bad idea?
:confused:

[The Overclocker]

nice idea, dont think there is any stuff like that, the best idea is to gett a small ammount of copper pipe and paint it in the paint and have it going through a spare 5 1/4 drive

[Arkamedies]

Hey! Theres an Idea! I wonder if it would be best to shield the tube from outside temps? Like encasing it in a clear plastic box.... hmmm... must try this.

Thanks again!

[r0ckstarbob]

wow. that would be cool.

so there IS paint out there that changes with temperature? whats it called and where can i find some?

hmmmm

*hamster wheel starts turning over...*

[IFMU]

Paint that changes color with temps.. Ive seen that before... very interesting idea... What would be the best material to paint it on to run the water through? Copper? Alluminum maybe? And you would prolly have to protect it from the outside air so the temps dont get too far off from the water temps...

***kicks hamster, doesnt move - Forgets why kickin hampster, reads another thread***

[Arkamedies]

Like I said, if we put the tube (I would use copper) inside a plastic box that would fit into a 5.25 slot so it is easily read, then it is protected from outside air and intrusion.

I think it would work well... let me get back to you on the color change paint! This could be grand!

[Flow]

Hey, great idea but maybe we don't even need this color change paint (I expect it to be quite expensive).

I thought of these little "safety thermometers" they use in aquariums. I'm sorry I can't find a picture of it right away, but I’ll try to describe them. It's a small plastic strip (black), about 1,5 cm (w) / 10 cm high and only maybe 1mm thick. On the front side there are (black) numbers (corresponding with the temperature range of the thing). I think it consists of two layers with some color changing substance in between. I don't know how it exactly works, but depending on the temperature the appropriate number will "light up" because of the color changing substance.

You could attach these thermometers at the outside of a copper tube or even better: inside a clear plastic one.
The only thing is the temperature range these things usually have: between 20 and 35 °C I think. But I know there are versions with a wider range. The good thing is that they cost less than 2$ !!

[r0ckstarbob]

well now

i think that would work just fine. hm. very cool.

btw - whats your sig translation flow?

though you can't see it in my sig at current (cause they're having problems with the signature thingy, my sigs not showing up in the thread)

Thanks.

got to go now.
*walks away into the setting sun*

[Arkamedies]

Okay... a little revamp here... How would you like the liquid in your sysem to go to the heatsink one color, and be a different color on the way back to the reservior? Read on *smile*

Thermochromic (a.k.a. "thermochromatic" or "chromatic") ink/dye changes color and appears or disappears as it cools down or heats up.

Depending on the kind of ink/dye you use, you can reach a vast range of temperatures to indicate. It can go from clear to green in a mater of 5 degrees ,or you can have a gradual change from one color to another over a wide range, such as 0 - 50C or even higher (why you would need higher I do not know! LOL
They come in 11 standard colors and usually start out as clear.

I think I would choose Green when cold, to Yellow when hot (yellow always indicates caution here in the U.S.) You can even get it in Purple when cold to Pink when hot.

Actually, now that I think on it... Green to Clear would be great....

Well, what do you have to say on this one?

BTW, the fishtank temp indicators would work perfect and are very cheap. Anyone who can not get them where you are, send me an pm and we will see if I can't get it for you and send it out!
Remember though... I know nothing about sending mail overseas. *smile* But we can try.

[r0ckstarbob]

hell yeah d00d

where did you find it and where can i get some?

[Arkamedies]

I have written two inquiries to the companies that sound the best for flexible thinking. They both say that they will make custom colors and can do bulk or single orders, so I asked them to give me prices and colors available.

I also made it very clear that it MUST be able to be placed in water for long periods of time without quick fading effects, and that if it can be placed with alcohol (names a few types) that that would be nice too.

The limitations seem to be that they can only make "blend" combinations that work with a color chart (i.e.: Yellow + Blue = Green) and so forthe.

I will post more as I get my replies. Lets keep our cyber fingers crossed!

[Arkamedies]

This is the most encouraging as far as having a place that can make it, but the color is limited and the cost is extreme.. here is what I got back:

Thank you for your inquiry.
1. We understand your application.
2. We can do this, but the color change would be different. We recommend black when cool to red when hot. We may not be able to change smoothly over the full range of 50-140°F, but we think we can come close. The material we will use is a thermochromic leuco dye. It is a 5 micron average diameter micro encapsulated slurry (capsules and water) that can be dispersed in water and alcohol. An information sheet is included with this e-mail.

The wide temperature range material you are requesting is highly unique. We believe that we are the only company in the world that can do this. We developed this proprietary material in a development project for NASA and wind tunnel testing. We can make about 200 grams leuco dye slurry (LD-S) of 68°F (black) to 10°4F (clear) for about $300. In volume, the price would be about $300 per kg for LD-S, black O29C40T.

Please tell me how you would like to proceed.

Best regards,

So as you can see, we are going to have to find another way top trick out the colors, unless ofcourse we have a very rich member who would like to buy us all some dye? Thought not... *smile*

Sorry all... I will keep searching.

[Arkamedies]

Well here is the response to inquiry number 2...


(Sir),
Thank you for contacting us and for your interest in thermochromic inks. First of all, your project sounds very interesting. As you may have picked up from our web-site, we specilize in manufacturing commercial printing inks, namely offset, flexographic, and screen inks. We obviously don't specifically make something that will dye water. If one of our inks had a chance of working, it would probably be our water-based flexographic inks. This is a water based ink and it is very viscous, having the consistency of a thick chocolate milk. Some of our printers prefer to "water-down" this ink with distilled water which is possible. Now, I suppose there's no limit to how much water you can add to this, but at what point does the ink lose its color changing properties. This is something we've never looked at because we've never needed to.
You are welcome to purcahse some ink and do some experimenting. You do need to know that our inks do not slowly change over a large temperature range say from 50 F to 140 F. Our inks will change within a 5-10 F range, this means that they are red and ten degrees later they are colorless. I am going to send you our sales policies, our colors, and pricing.
Also I would not recommend using an Alcohol in the ink, it will kill the color changing pigments.
Let me know what your thoughts are.

And just so you all know, the price per quantity is listed below.

[r0ckstarbob]

*sigh*

ah well. so much for that. liquid nitrogen and flouroinert don't even cost that much.


too bad. cool thought. guess we're reduced to stickers on our hoses.

[Arkamedies]

Hold on there r0ckstarbob! You ain't Elvis, so don't leave the building yet! LOL

We will continue to search until we have exhausted every possibility...... Me and my "people" that is..... okay me and a guy I met a few days ago?.... alright so its just me and a cat, but we got gusto!

Don't give up the fight!

[Christoph]

What a great idea. As I remember, the crazy guy in NZ who used flourinert said that liquid nitrogen wasn't that expensive. <gets idea but quickly kills it before it can mate and lay eggs>
How much is that color changing paint? Maybe some computer store owner could buy some and resell it in smaller and more affordable bottles, since most of us don't need a gallon of it anyway.
I don't like the changing water idea so much 'cuz I'm going to get a bong cooler, and I don't know if I want to breathe the stuff and replace it often.
<resuscitates hamster, hamster now has strong legs from much running>

[Arkamedies]

I will have to check on the price of the paint. I seem to recall it was a bit more expensive than the ink. (more applications for paint, don't ya know)

I will post what I find.

[Christoph]

MORE expensive than the ink? I'll have to look into that myself. That'd be nutty. I wonder who uses the ink, anyway.

Edit: Just fired off an email to Sherwin-Williams. They'll probably ask me if I was joking.
Just in case anyone has some luck, what range would be best? I asked for 15°C to 75°C just to be on the safe side.

[r0ckstarbob]

offset printing presses.

[Christoph]

Huh? How?

[Arkamedies]

Actually the color change clothing industry is still pretty strong. It mainly has gone to the light activated colors, but the inks are still used for coffee cups, paper, sunglass frames and stuff like that. All recreational stuff mainly.

It turns out that a guy on another web site also thought about this, the same day or the day before i posted, so I am gonna scan his posts and replies and see if he had any more luck.

[Christoph]

Quite a coincidence. Got a link?

[Arkamedies]

His thread is here (http://forums.2cpu.com/showthread.php?s=&threadid=10371) and it looks like he may have found something, but we shall have to wait until he remembers to bring home an address or name or somesuch.

Give it a read and perhaps bookmark it like I have so you can check back also.

Lets keep our fingers crossed.

[JaY_III]

why dont you just put a " mood ring" over the tubbing(copper part)?
As the rings change colour with your body temp.

[Christoph]

A mood ring probably doesn't have the necessary range of temperatures.

[r0ckstarbob]

yeah but it'd be groovy

[Arkamedies]

Okay, I have sent out about 15 more inquiries to chemical companies around the world and I have contacted Mr. Holoma with another idea. Since he is the one who said "I believe we are the only ones in the world that may be able to do this for you" I figured I would ask another option. See below for a small quote from my inquiry.

"Since we don't seem to be able to change gradually from one color to the next in the 50°to140°F range, what would be the chance of using multiple colors that would have overlapping ranges from 30° to 160°F or so. Such as 30 to 40 Red, 40-50 Green, 50 to 60 Blue, 60-70 Purple, 70-80 Orange etc etc. The colors for each range is not important, but having them be clear until their color is activated would work VERY well."

What do ya think? Multiple color variations while heating and cooling? And if it works, then we could possibly split costs and devide the stuff equally over several people since we would only need so much per system.

I will let you know how the inquiries come back.

[Christoph]

That'd be even better, as it'd give a more specific idea of the temperature. Is that for the color-changing ink? If so, I wonder how it might be adapted to an open bong cooling sysytem.

[Arkamedies]

"The material we will use is a thermochromic leuco dye. It is a 5 micron average diameter micro encapsulated slurry (capsules and water) that can be dispersed in water and alcohol."

That is the best description I can give ya without uploading the datasheet, which has a flaw and will not open.

[Christoph]

What's their email address? Also, how long do they take to respond?

[Arkamedies]

And they usually only take a day. So we may hear back from them on Friday.

[Ridenow]

Another idea you guys caused me to have:

[cmcquistion]

Hey, I'd be interested in that, too. If you get any idea on prices and such, give me an email.

:D

[Christoph]

Hey!
I got a response from Sherwin-Williams. Like I suspected, they don't make such things, but they gave two places that do.

Repsonse:

We appreciate you contacting us about heat Indicating Paints.
Sherwin-Williams does not have these types of products. Two companies that carry these products are Craig Adhesives at 201-344-1483 or Tempil Products at 908-757-8300. You may contact them to find out more about their products.
The Paint Guy


I'm going to try to find a website. I'll be back!
That formatting has to be the stupidest thing I've done to date! At least it looks cool.

[cmcquistion]

At Home Depot they have Indoor/Outdoor Themometers for $10 and up. These are little boxes with a digital readout that tells you the temperature indoors and out. They do this by having a little sensor attached by a wire that you run out a window to the outside. Since the sensor is designed to be waterproof, I don't see why you couldn't use it submerged in water.

I made my water cooling system with a "T" attached to the line feeding the pump. (I got the idea from an article in the watercooling section) Attached to the "T" is a fill tube.

You could feed the sensor and wire down the feed tube to the "T", here it would report the temperature back to the readout, which you could have mounted on the outside of your case so you have your room temperature and your water temperature.

P.S. They have these Indoor/Oudoor thermometers everywhere, Wal-Mart, K-Mart, Radio Shack, etc. Make sure that your'e getting a sensor with an attached probe, however. The newer thermometers have a separate box that you place outside to tell you the temperature, but these are not suitable for our use.

[Christoph]

Someone else will have to look for those two companies. I may have just killed a second CPU, and I've had enough of computers for this week.

YEp, I have seen several types of these. As a matter of fact I hhave one in my kitchen window over the sink so I can check inside and outside temps.

The thing is though, we want this simply for the "WoW" factor. It would justbe a great effect to have the fluids in your cooling system change colors while you work.

Even if it does not work out that we can get a goodcolor change system going, I may figure out what my average temps are with my new system and just buy some for tyhat range.

I am still getting replies back, so I will post them on Monday. I gotta get to work now.

[Christoph]

I noticed that on colorchange's site, that their ink consists of tiny capsules of the ink. I wonder how well they'd mix with paint.

Edit: I was sure quick to get over that CPU. I just hope they believe that the chip was screwy (as I think it was).

Edit2: I found another site, here (http://www.craigadhesives.com/Specialty.htm), that also seems to have some relevant stuff. I'm emailing them and will post back here whenever I get a response.

[Arkamedies]

New news....

Okay, I got three "We can't help you" letters so far and one fairly promising lead. A company called Chemrez Inc. (Philippines) sent me a return response that directed me to inquire with there associates in Taiwan, the Kelly Chemical Corporation. These folks apparently already have a chemical that color changes with temperatures and may be able to help us.

This may be good, it may be disappointing.... Do you know how many pounds 250 kgs is?..... It is 551.25 pounds. That may be the minimum purchase quantity. That comes out to about $1.84 per pound + shipping and handling.

I am awaiting the response. If it comes back that they do have what we are looking for, I will discuss shrinking that order (a lot!) so it is not so horrid! LOL

I am still working on it, but we probably won't hear anything else until Monday. I just hate to give up the fight on a good idea *grin* :cool:

Or perhaps we could take a poll to see how many people would actually want that: $1.84 a pound seems resonable. Then whoever wants that could send their mony to someone who is willing to purchase all the 240kg.

edit: or another idea perhaps if you told then our situation and said that one person does not want all of the 240 kg but they would get many samll orders. That might work. Ofcourse considering that many people want to buy this stuff, we could also contact other overclocking sites and ask them if they are interested. That might work.

[Christoph]

Even if we got the same amount of interest that people showed in the OC shirts, we'd only be able to sell maybe 50-100 lbs. That sounds fine if someone's got the time, but I don't believe that it'll work with their minimum order.

[Arkamedies]

I had that thought also. But that too has some problems. We shall see what the e-mail brings over this weekend and see what we get this week.

I would like to know how many watercooled people out there might be interested, but I am sure they would want to wait and see how much the actual cost would be and what the color and situation would be.

Perhaps after we get a few more solid facts we will run the poll. Thats a great idea Coolio, and I am glad someone other than r0chstarbob, IdeaMagnate and myself is interested in this. Lets keep rockin, and hope for the best.

if anyone does do this i want pics damit

oh and i dont think the paint is too expensive because it is used for getting the right heat on the bottem of a frying pan

I just bought my w/c stuff a few days ago from DangerDen<Maze2, eheim 1250, heater core, fixin's> and I was also thinking about how to keep an eye on my temps. Although I want a doc to monitor the normal temps, i wanted to keep an eye on it from just walking past the door. Good stuff guys, I congratulate you for being quite innovative. Bravo! Keep it up, cuz I'll be readin it! :)

[ROH]

Keep us all posted! I like the idea of watching all that rainbow water.

perty, george!


I think a good mod for this would be some type of bubble or cup on the top of your case that the liquid passes into then back out from! the pump pumps it in and gravity would pull it out again to the waiting res. Hmmm....

I so, have to get my water cooling parts together. :D

[Arkamedies]

I am a very patient man, and if I have to work hard to get this done, then so be it... but damnit, I KNOW it can be done, and if we keep going, I can just feel that it WILL get done.

Keep an eye open for this one guys... its gonna be a grand fight! I have the entire world inundated with e-mail inquiries, and with rockstarbob and IdeaMagnate pitchin in, it ain't got a chance of evading us! *evil grin.... maniacal laughter**

:D


What many folks need to remember on this also is that a lot of the reason we are doing it is for the wow factor... the temp gaging is just a side effect! LOL

[Arkamedies]

Update:
It appears that the inquiry, although not able to be done by some of the manufacturers out there, is making it's way into the hands of helpful people.

Today I received the response below... and of course I had to check it out.

INSERTED ***********

We are very pleased to hear from you and deeply appreciate you have the interest in our products. Based on y(ou)r description, the product you request must have a gradual color change from 5 ~75 deg C. For our recommendation, the liquid crystal will be suitable for y(ou)r application more. On one hand, the LC is more sensitive than the chromic, so it can achieve y(ou)r requirement. On the other hand, it may have difficult for multi-colorchange to chromic from 5~75 deg C. But at present, we don't offer the LC. But it you have any further inquiry about our product, we welcome you to contact us directly.

Nice!
I'm still waiting. Could be a while though. :(

Given that it's about 10:30 over here, your sig seems strangely apropos (http://www.m-w.com/).

May your dreams be filled with color-changing case mods.

[Maximus Nickus]

i've seen a nissam primera before that was apinted in this weird paint! its like looking at oil(all rainbowy) and it changes colour!

[Wicked Klown]

I'm not sure if this will help on price but the paint I used to do my rig changes color when light hits it and it was $11 a can. So I'd say the paint that changes due to heat would be about $30 if not more.

[Arkamedies]

Thanks for the input guys! I will add them to my "look into" list. You never know what may come in handy!:D

:cool:

EDIT:

Well I got another response, and frankly it is not good. I don't think these people really understand what we are trying to do here. The letter I send out is very specific on what the application is for (so they don't send me a $300.00 package of something that doesn't work). Below, you will see the latest response:

Dear Sir:

Thank you for your interest in Hallcrest's products.

Unfortunately, although we do have thermochromic products we don't have
anything that would be suitable to your application.

Again, thank you for your interest and please contact us again if you
have any other applications.

Not to rain on your parade but with the precision measurements available with cheap digital thermometers, this seems like a waste of time. :confused:

No rain here.. lol... Not to worry friend. The title is a bit decieving. It is actually for the "cool colors" factor, or "wow" of watching your system change colors as I stated a few times further up the posts.. Its mainly for fun. But thanks for stopping by.

Its all good.:cool:

gee whiz guys. maybe we should get together and have a cyber hug and start picking out cyber curtains - whoops! who dropped the cyber soap?

[cowanrg]

hum, i had an idea, its not what you guys are looking for, but it may be a substitute.

you know those little credit card shaped thermometers that change color due to heat? they tell you what temp it is by what color it shows? since they are SO thin, you could paste one onto a copper pipe, and have a window so you could see what color it was. if all else fails, that would work.

any material that changes color with temp SHOULD work.

and remember, the computer really only operates at 20C - 60C (for most of us...). some comps get colder, but few.

[cmcquistion]

I went and bought one of those Indoor/Outdoor Thermometers at Home Depot for $10. It works great! I ran the little temperature probe into the computer case and down my fill tube. It is sitting in a "T" connector just before the pump. It gives me very precise temperature readings of the water at that point. One thing, though. This is the water temperature after the CPU waterblock, not before. I know now that the water temperature usually runs about 82 - 85 F before it gets to the radiator. I don't have any way to measure the temperature after the radiator, unless I put in another "T" just after the radiator and before the block.
This is good information, however, because I was wondering whether I could put in a few more waterblocks in my system. Since the CPU consistently runs about 98 - 105 F, however, I was worried that I might only heat up other components with the circulating water. Now I know, however, that the hottest the circulating water could be is 85 F and its probably 5 or 10 F cooler than that after it goes through the radiator.

$10 for peace of mind.

[Christoph]

BLASPHEMY!!!! BLASPHEMY!!!!!

That's not what we're after. What we (or at least I) want is a surface that changes colors with the temperature. I'll probably do something with the boring LCD thermometers on my bong cooler anyway.

[Arkamedies]

Calm IdeaMagnate... calm... find your happy place... calm.... there, now isn't that better?

Most folks have not read the rest of the thread to see what we have been discussing. We can handle that. Just remember, we have stated rather plainly a few times now what it is we are going for, and with responses like the suggestions of devices for us to keep track of temps, you can tell they have not read it all.

That is okay, the more people who see this thread, the more will want to join us when we figure out what to use!

Its all good.. :cool:

P.S. EDIT: By the way IdeaMagnet, have you ever heard of 3M™ Fluorinert™ Electronic Liquids... LOL... also known as FC-3283? This is another one I am playing with just for WOW factor....

Having my motherboard and slotted cards all submerged in liquid with a refridgerated coil and impellers directing fluid directly towards the chips.... mmmmmmm YUMMY! Or as a normal liquid for use in the cooling system. It can spring a leak and not damage any components in your system.

It is rather spendy, but it may be worth it. $27.00 a pound (it comes in liquid form, so why they go by pounds I can't say) but think on it as 11 punds to a gallon, and you have the price... plus it would be best to keep it in a sealed system.

[Christoph]

I feel better now. Thanks.

Yes, I've heard of Flourinert, but I think that you're craky to buy it if the $500/Gal price I saw was correct. That's some insane stuff, and if you've got the money, enjoy! It'd be an expensive setup, but the cool factor would be immeasureable. If you do that, take some pictures. Maybe you could even add some color to the flourinert.

[Arkamedies]

If I add color, it is considered a "contaminant" and can cause the fluid to become conductive... zapppppp-o-rama! Ungh.. bad thing... baaaaaadddd.

I am still searching for the colored stuff, the submerged system is going to be my main system. I am building 2 others for experimenting. I will submerge my dual and place the refrigerant coils in the liquid as well. The temperature so far is indicated at about -17F or so. But until my samples arrive, I can not test anything.

There is a demo video of the FC-"class" of liquid. They take a 19" color television and lower it into the FC-77 and then turn it on and watch TV while discussing the product..... that is coolness.

"Its all good" :cool:

[r0ckstarbob]

just be aware - flouroinert isn't cold (i don't think) - it's just EXTREMELY resistant to thermal deviation from what i understand. it's best used in colaboration with LN2 or dry ice - but you'll have to keep putting something cold in there or purchase an LN2 compressor. Once you get the temps down, fluroinert will keep em down for a long time, but even that stuff will find equilibrium eventually and come back to room temperature unless you continue to feed something cold into it.

[Christoph]

No, rodkstarb0b. In the article where I found out about Flourinert©, the guy also used LN and the Flourinert© gelles after a whole from the extreme cold. If you do go that route, find out explicitly the freezing point of the Flourinert© that you buy. You might have already done this, but I just wanted to make.
Love those extended chars.

[Jackywebdesign]

any news on the color thing?

[Christoph]

Oh yeah, I need to get back on that. Thanks for bringing it back up.

[Arkamedies]

Well, I got this a few days ago and was hoping to hold out to see if he got back to me quickly... here it is so far. Not much overall...

Dear (Sir),

I am trying to find a suitable product for your application . For this I may need some time. In 2 weeks time I will report of my success to you.

Thank you,

So There ya have it. Lets hope he comes through for us. :D

[The Overclocker]

glad to see this is still going, no use to me though, i have green tubes...

[cowanrg]

i would really like to see this done! im just starting to put my setup together. get my block today, fans tuesday, and heater core sometime next week. already have pump, resevoir, and tubing. (tubing is clear silicon with nylon reinforcing threads).

some cool color changing liquid would be cool, but unfortunately, mine would always be solid, becuase its always at full load though...

[Arkamedies]

I plan onsticking with this until there is no one left to ask about it. So far, out of all the world oragnizations that have a product that MIGHT do what we need, I have contacted about 2/3 of them.

Keep them fingers crossed! LOL
:cool:

[Jackywebdesign]

bump...

[Jackywebdesign]

any new info???

[Arkamedies]

No new info so far. Several places have chosen not even to answer. Perhaps I should lie and act as though I am looking to make friggen shirts or something... sheesh... These people in the "Ink and die" community are some snooty supremists.

I will deliver as soon as I get more word.
:cool:
Its all good

[Arkamedies]

Okay... just to let everyone know, this is going no-where. I have gotten no responses for some time now, even on multiple inquiries. So, I think it is time to let this lay for now. I will research it in a bit more detail and continue the fight.

It all good :cool:

[Christoph]

Yeah. I agree that this needs a rest for a while. How about one of us starts it up again in a couple weeks. http://koti.mbnet.fi/antiqser/smilies/cry2.gif Sorry to hear that you'rew not having much luck either.
http://koti.mbnet.fi/antiqser/smilies/missiler.gif We know what we need to do and http://koti.mbnet.fi/antiqser/smilies/kiss.gif what it'll be like to finally get this done.

[IFMU]

Yea know the funny part about this? I saw a commercial on TV yesterday I think... It had Legos that changed colors in different temped waters... Didnt get the site or phone number, I was way super busy... But thought it would be a hella idea for a resivior...

Good thought. Now how to get this thing started again. http://koti.mbnet.fi/antiqser/smilies/thinking.gif

After reading through this thread I want to help finding companies that might help us out myself. I'm not watercooled yet, but I have already got my pump and clear pvc hose. So I might go out searching the web after temp sensitive fluids.

I thought of another alternative. How about making an electric thermometer control a neon light. Alternating the neon intensity level according to the temperature thus giving a visual impression of the temperature. It should be possible to make this..

[Crash893]

how about one of these things

its not exactly what you wanted but im sure you could use some lighting effects and stuff

i hope every one knows what im talking about this picture is pretty crappy ( becuase the camera is pretty crappy)

if you need better pics let me now

heh, thats a cool, idea.. i just got one of those.. there kick a$$, but i cant read mine yet.

[RoadWarrior]

Hi folks, interesting thread, can't quite figure what temps you are really going after. Since I guess cryo/icepack/multipelt/antifreeze systems are going to want a range say of -20C to 10C, whereas people with bongs will want about 15C to 40C and peeps with regular sealed radiator systems will want I guess about 20-50C.....

I know you're going after the liquid solution, but was just thinking about the "mood ring" suggestion among others. Well the range of temps that are useful for most people with the radiator setups would pretty much approximate the human body temperature range. So also in fact, those thin film "fever thermometers" that you see in a lot of dollar stores nowadays, would be somewhat useful, they're the ones you stick on your forehead to see if you're running a temperature. IF you've got a few bits of copper pipe in the system it might be worth strapping a few of them round them anyhow.

Another thing I thought of as an indicator, though it's a calibrate it yourself jobbie. Is those battery testers that you get on duracell batteries. They are actually a temp sensor with a resistance strip of some kind on the back. When you hold them down the strip heats up a certain way according to how many amps tha battery can still deliver. Now those are pretty much free if you know someone who uses a lot of batteries. This would only be good for people with ambient and above cooling systems I guess. And the temp range might be on the high side. But what you could do is use the metallic strip on the back as a conductor and affix that to copper pipe, heatsinks etc, by the end and however far it changes color along the length gives some indication of temperature. You'd have it standing away from the heatsource of course.

Anyway, if you wanted lots of cheap sensors, those might work out, stuck all over every bit of your system :)

The liquid idea is really awesome though. Hope something comes of it soon.

:cool:

from what i have seen you have had some good replys on the subject so just go with those

[CrystalMethod]

Try checking 3M or DuPont.

[Crash893]

this was sort of my idea

you read the bubble that is floating in the middle

if no bubble is floating you just take the temp inbetween the top and the bottom

like 74 is all the way up and 72 is all the way down its probably around 73degrees

the one i have now has a range from 68F to 80F but the better ones have more bubbles and more range

im sure you could make one of these your self

anyway here is kinda what i was thinking of

[combatmedic]

What I envision is kinda what crash posted but not quite. You would have the Galilo thermometer inside of a Lexan box. It would be sitting/glued on a piece of Lexan that has holes drilled in it. Below that plate would be your resivor and pump. The water comming in would flow over the thermometer and fall into the res.

[combatmedic]

I don't know the ranges that you want, so maybe someone else should contact these people. From their site the 'Microencapsulated liquid crystal slurries ' looks perfect.

[Maximus Nickus]

What about this?

I have seen these stand up cylinder glass things with floating coloured things, and they float at different heights depending on the temperature, so why not try to use one of these and somehow have water flowing around it (not through as they wouldn't be able to go up and down they would just fly!) and after a few minutes the water inside would be the same temp as the water going through your system, it wouldn't be that accurate untill your system has been powered up for a bit but after it would be as they have markings on the ouside, it would look really cool with a light and a window and its quite practical to.

What do you think?


Nick:cool:



P.S. Eventually our P.C.'s will be aqquariums with fish flowing around!!!
