Ok here are now a final update of this project.

I have reworked the hole Windows Software V1.8 and added many new feature.
http://www.keiang.de/modules/PCcool/...re_18_1_sm.JPG

http://www.keiang.de/modules/PCcool/...re_18_2_sm.JPG

http://www.keiang.de/modules/PCcool/...re_18_9_sm.JPG



I have finished 2 extension for this project:

- "8 channel light control" -> "8 channel light control"
- "Emergency shutdown / alarm output / pump check" -> "emergency shutdown"


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. ( 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/...re_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

What was the total cost of this build? (man hours excluded)

I have seen many of these for sale, and to be honest, all the ones on the market look like crap compared to this one.

Have you considered making some money out of this and building a few of them?

Wow! That is really cool. I'm with dsio, start making some money of those. Whether it through eBay, or through your own website. Those are awesome!

I realy dont know, mybe over 300€ ???. But this was not the main factor. I invested many hours in the software and much more in the firmware. I'am working on the firmware now over 3 years and realy finished first now.

The fan control i have developed offer 3 different mode:

1.) manuel - each fan channel can be configured to a fix fan speed
2.) target temp - ( also called PID-regulation ) each of the 8 sensors can be configurated with an own temperature, it is also possible to configure with of the fans are responsible for cooling this sensors. In this mode the fans are automaticly controlled so that the configured temperature are reached for each sensor.
3.) step - Each fan channel can be set in a step mode ( also called 2-point regulation ) in this mode the fan are automaticly swich off or switch on with an configured fix speed.

Everthing can be configured by the Windows Software ( over USB ) or with 2 buttons on the front.

http://www.keiang.de/modules/PCcool/Software_18_3.JPG


Here an example of the mode "target temp.":
- red line = temperature of sensor1
- white line = speed of fan1
- configured "target temperature" = 35°C

As you can see the speed of fan1 controlled automaticly:
