At this time I am not looking to take on any additional projects.

I'm from Peru. I'm going to do a spinning LED's project, but it's going to be used as a 2D spinning that you can place onto your bicicle wheels. Your project just gave me some hints. If you are interested, get in touch with me to see my project when it's done =).

Great, send it in when you are done.

I watched the PWM fan controller with temp sensor and i really liked.

Now I'd like to make my own fan controller for my computer since any of the commercialized controllers aren't for my likes.

I'd like to control more than a single fan.

So: Is there any way(I'm sure there is) to control 5 fans with individually parameters?

Thanks in advance

Yes, but you would need to use a larger microcontroller with additional I/O lines.

I'm used to putting 2.2k ohm resisters in series with an LED for 5vdc power. this says 56 ohm. Seems like a huge power flow. lol

Yes, LEDs will still light with very little current.

I am looking a kit of stair lights, could you tell me if yours works with 12 volt LED lights. If it is not possible, could you make one of 12 volt and how much is for it. Thank you. Jose Gutierrez

Hi, i am trying to design a temperature controlled fan using LM35DZ. i have tried a number of circuits using lm741 opamp and lm358 dual opamp but nothing seems to work. i need your help in terms of a circuit diagram for this circuit. please

Hey Alan,

I am a beginner electronics student at Millikin University and chose your PWM fan controller as my final project. I looked at your schematic and I don't know where collector of the NPN transistor goes. does that go to one of the leads on the molex connector of the fan. Any help would really be appreaciated.

Replied on: 7:34pm 12-15-2012

That gets connected to the negative of your fan. This is probably the black wire in your molex connector.

I saw the project of the Hard Drive Clock recently, so I decided to make one for my final work at technical school. Could you tell me some hints to make this job easier? I thought of using three colors of LEDs instead of two, for a better view of the colors, mainly under natural light. In what language did you write the source code? Could you send it to me?

Waiting for your response,

Replied on: 9:47pm 12-15-2012

You can get the code here.

It was written in PicBasic Pro
