well am waiting on a few things left.new inline drier and a bag of charge port solder on fitting so i can charge and adjust the system.i hope by this weekend i can get it mounted into the computer case lower slide out tray.first i have to make the tray i guess,

hey one thing i am looking for if anyone knows of where i can get a reasonably priced LED digital temp readout for the fron of my pc.i am looking into soldering myself one together but i dont have alot of the time i would like to.now i have about 6 or 7 LCD readouts so i am not looking for one of those.LED is what i want.
i have been looking in the forums for a used controler from a vapochil unit or a Maxxxpert MX-EVA3 unit that i can buy for parts.anybody it would help my project if anyknows let me know.

how much did u spend on this already?

bowman1964 09-18-2002 03:51 PM

MORE THAN I WOULD LIKE TO HAVE.I WILL GIVE A BREAK DOWN AT THE END BUT I TELL YOU.IF YOU HAVE TO BUILD ONE FROM THE GROUND UP LIKE ME AND BUY ONLY THE BEST LIKE I AM DOING.I BET I CAN BUY A NEW VAPO WITH THE MONEY I WILL HAVE SPENT BEFORE I GET FINISHED.BUT I WILL BE THE COOLEST GUY IN TOWN.BUT A BROKE COOL GUY.LOL

pun intended?

I hate it when faggots say that. hehe. EVERYONE makes a pun somehow, somewhere.

bowman1964 09-18-2002 05:07 PM

WELL I GUESS YOU MIGHT BE RIGHT, I AM GETTING TO OLD TO BE COOL ANYWAY.MY KIDS SAY I DONT KNOW WHAT KOOL IS,THEY ARE PROBABLY RIGHT.BUT I BET -60 IS STILL COLD TODAY.AND THAT IS WHAT I WANT TO HIT.SO I MIGHT NOT BE KOOL BUT I BET I KNOW WHAT COLD IS......:dome: :dome: :dome:

SonixOS 09-18-2002 05:38 PM

nonono. I didnt mean it that way. I was just saying that other people usually say "pun intended" when they use the word cool. Pun for cool as in hip and cool as in cold.

hehe, sorry for the misunderstanding. come over the pro/chat and enlighten us a little. We were appraising ur work there the other day.

ok well i thought i might show everyone what a ac project like this is going to take as far as tools go.now remember you can do this with out the fancy tools like me but i have them so i am going to use them...
in the pic you well see from back to front.
30lbs container of r22
refrideration oil
set of ac gauges(good quality set)
raytek st30 temp gun(lazer guided)
a couple of indoor outdoor lcd temp units(will go down to -58f
my new tubing bender(robinair ac tubing bender)
tubing cutter
silver solder plus solder(bowman 21572)
lead free soilid wire solder70/30 (napa#777-1865)
solder paste
and my trusty calipers

You might have already answered this, but how much did you spend on your gauges?

pHaestus 09-19-2002 02:43 PM

LED thermometers:

http://www.qkits.com/serv/qkits/vell...ages/K6003.asp

(only goes to -50)

Regarding vapochill controller; you talking about the delay before start that lets the temp drop? I am fiddling around with a circuit to do exactly that right now.

bigben2k 09-19-2002 02:53 PM

Dang!

90$ CAD?

I was gonna tackle the delay starter too! What do you have so far? (PM me).

pHaestus 09-19-2002 02:55 PM

easy to do on a timer; more complicated based upon temps. You can use a 555 or just make a comparator circuit.

i believe i paid $180.00 for the set when i got them.

and i am looking at the LED temp gauge ,but i am trying to build one from scatch cheaper if i can.i can find the LED board pretty cheap online now i just am not sure what it will take to make the circuit work properly.

pHaestus 09-19-2002 03:33 PM

#rotor has a full circuit for such on his website. Can't find the URL to it for some reason now

bigben2k 09-19-2002 03:52 PM

Bowman:

Try this one

It also has a link to the backup circuit.

It's still have to be adapted with a thermal probe, but it's almost there...

pHaestus 09-19-2002 09:11 PM

Here is sort of thing you may look for instead of the vapochill controller:

http://cgi.ebay.com/ws/eBayISAPI.dll...tem=1767762283

Link with a normally closed relay across reset button; when the temp gets where you like it then the relay will trip and the PC will boot.

Keep your eyes peeled and you might find a cheaper one.

On other hand you might be able to get a controller from asetek via a us distributor. Whichever is cheaper...

bowman1964 09-20-2002 11:48 PM

i really want to say thanks for helping me find some links on a temp unit.i am looking at the one on ebay real close.i am emailing the guy to find out how low it goes and it i need a thermistor or not.
i am at a point where i need to catch back up with my funds.am at $400.00 so far in just a week.so i am going to slow down om my speeding a little.but really all i have left is the LED readout and aluminium angle and flat plate.i would have gotten the aluminium by now but the guy who is selling it to me has been on vacation this week.and he is going to bend and weld it up for me.my brother by the way.he makes custom aluminium signs so he can bend and router out a perfect pc case.I showed him a pic of a LIAN LI case and he said no problem.so he is going to try to rough it in and i will finish the case with the chiler in the bottom

pHaestus 09-21-2002 12:41 AM

In the description he mentions one PID with a secondary relay. That is the one you would want. Connect a normally closed relay to that one, with the outputs of the relay going to the motherboard's reset header. The system would then keep the reset button pressed down (in effect) until the system reaches the desired temp. Then the relay switches, the reset header is no longer shorted, and the system boots :)

bowman1964 09-21-2002 07:22 AM

well i am biding on the unit now.checked out what i could and looks to be a good unit for what i need.just hope my bid holds.if not o well.i wont be on today to check it much so maybe i will get it.

i almost forgot look what i just got in for the project.sight glass and box of access vavles.sight glass will help me get the just right charge with out over charging.should make it easyer i hope.

bowman1964 09-21-2002 11:43 PM

well lost my bid.the other guy wanted it wourse than i did sold for $81.00

godsdice 09-24-2002 10:08 PM

Don't have much experience charging systems. Could you explain where the gauge and access valves go and from where do you charge the everything. Also, does the compressor already have oil in it?

yes the compressor will come complete with a full charge of oil.
there are 3 tubes comming out of most ac compressors.you have a small one called the hi pressure side. and a larger suction line called the low side.then you most of the time have one more large tube by itself that is used for fill purposes.,
now i am going to show you a pic of my new one.one the left you will see the fill tube.on the right you will see one larger tube(low side suction) andone smaller one marked hi side.now the gauges will connect to scrader ports i will solder inline in on the hi and low side to charge and monitor the system.
hope this helps

SonixOS 09-24-2002 10:28 PM

48 for TX Valve, 22 for hard start kit and 75 charge for installation.

does that sound reasonable to u bowman?

well that is about right.now you know that the hard start is just a start capacitor to give it more juice. just to start up easer underload.which is a very good thing if you can do it.always use one if you can will make the compressor even last longer.75 may sound hi but it will take him a hour to install the tx vavle and about 15 min on the start kit.so the charge is a fair price if that is what you want.

well finally got my aluminum cooling tray finished so now i start my fitting and pipe bending.
just incase anyone was wondering this cooling tray will slide in the bottom of my custom aluminum pc case.so i can slide it in and out for ease of my old butt working on it.ha ha ha

i know alot of people wanted to see my block so here it is.i snaped a pic while i was stripping my pc down.sold my xp333 and xp2100 w/512 pc3000 to a friend.now my abit at7 maxx 2 is in and my corsair 512mg pc3200cl2 is in.now i have to wait on the xp2600.but that will be end of mid oct before i can buy that.

well i know its been a few days, trying to get caught up.I am working on too many parts at once.(1) I am trying to inprove on my block design with some added features into the new design.when new block is finished, i have designed a way to slow down the freon for the first 12 "s or so of the maze without making the channels any smaller.this should inprove heat transfer.(2) I am designing a way to adjust the freon flow to my chiller unit with out losing a freon charge,or using a exp vavle.this is trickie to do.still trying to get the best subcooling possible without overloading the compressor.trying to make the condensor do most of the work..well here is a little progress pic
