digital temperature/fan-control with LCD for PC, selfmade

[keiang]

It is done, a final version of a guidance how to built up this fan/temperatue-control (http://www.keiang.de/modules.php?name=Downloads&op=getit&lid=24) is available now
for the Download. (press button "Auf gehts" to start download)
Here you can find some pictures (http://www.keiang.de/modules.php?name=Album&file=kat&kateg=die%20Luefterregelung) and a detailed desription in english (http://www.keiang.de/modules.php?name=PCcool_en)

the main characteristics in the overview:

- by micro-controller digitally regulated fan/temperature-control,
regulation works 100% independently of the operating system (e.g. Windows...)
- with up to 8 sensors the temperatures of the PC's are supervised and
the speed of the fan's is adapted automatically
- very exact temperature sensors with a accuracy of 0,1°C
(DS1820)
- several safety functions protect against overheating the computer-hardware
- low-loss control of the fans by pulse-width-modulation
(PWM), saves energy and produces no additional heat
- the fans can be regulated into a range from 40% to 100%
- indicate the fan's "rpm" also in PWM mode,
over the whole work area
- USB-interface
- also for watercooling suitable!
- displaying of all values on LCD 1*20/2*20/4*20 (temperatures, fan's "rpm", alarm status...)
- simplest operation over only 2 keys
- very flexible configuration possible (alarm temperatures, sensor-fan config, hysteresis...)
- store of all settings in eeprom

Sorry for the bad english, i will try to improve the translation but it is a little bit hard for me. Maybe someone can help me?

:welcome: to BE keiang. Hope you enjoy time here. We are here to help and take you to the BleedinEdge.

That is one very BleedinEdge piece of work :thumbs: . Glad you told me how to download the file by pressing "Auf gehts" button. I woudl have been fumbling around the site for a while.

BTW your English if perfectly fine. Do not worry about it.

Below is some information we post for new members that some have said was helpful such as The BleedinEdge Story (http://www.bleedinedge.com/forum/be_pagegen.php?id=about_be). When we are not tweaking our rigs or helping folks out we put our unused cycles to work the the BE Folding@Home Team Info (http://www.bleedinedge.com/forum/showthread.php?t=1418)

If you are interested in telling us a bit about your User Name...what's it mean?? (http://www.bleedinedge.com/forum/showthread.php?t=1319) or some info on Your System (http://www.bleedinedge.com/forum/showthread.php?goto=lastpost&t=5856). There is also Post Your Pets (http://www.bleedinedge.com/forum/showthread.php?t=1766), The Computer Room Thread (http://www.bleedinedge.com/forum/showthread.php?t=490) and even a BE Family Photo Album (http://www.bleedinedge.com/forum/showthread.php?t=2601&highlight=photo+album). Or maybe you would prefer to read through the Forums on BE (http://www.bleedinedge.com/forum/index.php?).

In the end we hope you relax, put your feet up and stay awhile.

That looks really good i will be bookmarking this for future reference, as for translation to english it looks fine, also before i forget :welcome: to our freindly community

If someone are not able to connect to my website and want to get the "HowTo built this Fan-Control", please simply send me a email to "rg256@gmx.de" with subjekt "HowTo Fan-Control" and i will send you the full archive containing a screenshot of my website, all plans and the HowTo.

A "small" update of the project:

1.) Instead of a normal Text-LCDs (HD44780 etc.) also a graphics LCD can be connected now, with that some more information can be indicated at the same time. I used a GLCD with the controller "T6963C" (240 * 64 pixel) here.

Here is a short video: Video of the GLCD (http://www.keiang.de/modules.php?name=Downloads&op=getit&lid=38) (press button "Auf gehts" to start download)

2.) The software for Windows is now also almost ready. At this time all dates of the regulation can be indicated and adapted (temperature-, fan-, regulation dates as well as all configuration data: temperature limits, sensor-fan config, etc.).
As next a small interface comes for the software "Samurize" www.samurize.com included, with that everyone can represent the dates graphical likes he want to.
You find a precise description and even further information here: Windows Software (http://www.keiang.de/modules.php?name=PCcool_en&file=Software)

http://www.keiang.de/modules/PCcool/software_1.1_1.GIF

The most important enlargement is to be let indicate all dates in a diagram. With that one gets a very good overlooks about the regulation behavior and with that whether all attitudes are correct.
The diagram can be stored if required with a right click as a graphics file.

3.) With this enlargement bigger fans (>2W) or several can be connected at the same time. in total 6 fans with each 10 W can be connected.

Very nice work keiang! :thumb:

[Rukee]

It`s cool as heck!!
I wish I could understand the guide. :scratch:

A english mirror of my side is under contrustion, there you can find an english HowTo and other stuff...

Just a short update of this project. I have added support of a new graphic LCD:

graphic LCD during operation ( all data scrolling from down to upward ):

Hello keiang and :welcome: to BE, enjoy your stay.

That some serious work, very nice indeed. This will go great for my next project.

Cheers

Ok here are now a final update of this project.

I have reworked the hole Windows Software V1.8 (http://www.keiang.de/modules.php?name=PCcool_en&file=Software) and added many new feature.

http://www.keiang.de/modules/PCcool/Software_18_2_sm.JPG

http://www.keiang.de/modules/PCcool/Software_18_9_sm.JPG



I have finished 2 extension for this project:

- "8 channel light control" -> "8 channel light control" (http://www.keiang.de/modules.php?name=PCcool_en&file=lightcontrol)
- "Emergency shutdown / alarm output / pump check" -> "emergency shutdown" (http://www.keiang.de/modules.php?name=PCcool_en&file=alarmout)


extension: "8 channel light control"
http://www.keiang.de/modules/PCcool/PIC02616_sm.JPG

- With this extension can 8 additional light channels manages and to be programmed own light sequences. Here a short sample movie: light sequence (http://www.keiang.de/modules.php?name=Downloads&op=getit&lid=56). ( to start download click button "starte download" )
- it can be also showed the speed of a fan as bar graph or as a binary value
- alle settings can be done in windows software:
http://www.keiang.de/modules/PCcool/Software_18_8_sm.JPG


extension: "Emergency shutdown / alarm output / pump check"
http://www.keiang.de/modules/PCcool/PIC02603_sm.JPG

The emergency shutdown works in this case not over the Windows software but ove the connection "power switch" of the main board. Through that the emergency shutdown is independently of Windows and works much more secure with that.

- With this extension the PC can in the alarm case shutdown or completly switch off.
- In Addition there is another relay with that on the extension an additional fan or a pump in the alarm case can be activated.


In the case of following alarms the emergency shutdown is activated:
- temperature of a sensor rise over the defined value ( overtemp. )
- a temperature sensor turned out
- rate of a pump or flow sensor lies under the defined value or completely breaks down
