digital temperature/fan-control with LCD for PC, selfmade
Posted: January 2nd, 2005, 9:34 pm
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:
- 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 monitored and the speed of the fans are adapted automatically
- very exact temperature sensors with a accuracy of 0,1°C (DS1820)
- several safety functions protect against the overheating of 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 within a range of 40% to 100%
- The fan's speed is also shown in PWM mode, over the whole work area
- USB-interface
- suitable also for watercooling
- display of all values on LCD 1*20/2*20/4*20 (temperatures, fan's "rpm", alarm status...)
- simple operation over only 2 keys
- very flexible configuration possible (alarm temperatures, sensor-fan config, hysteresis...)
- storage 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?

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" 
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.

on this graphic LCD I have tested now a
