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

It is done, a final version of a guidance how to built up this fan/temperatue-control is available now
for the Download. (press button "Auf gehts" to start download)
Here you can find some pictures and a detailed desription in english

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?

 

Very impressive!

 

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 (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

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.

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