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.

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,

You can get the code here.

It was written in PicBasic Pro

Hi Marco,

Everything that is available is shown on the project page. There is no kit for this project.

I built the Stair Light project and everything works great. Thank you so much. I have a small request to make. Is it possible to send me (or buy) the source code for step by step lighting. I have the "all led on" version but I realy want the version to light each led step by step. Thank you so much, Lucian
Replied on: 12:41pm 09-27-2012

Yes, the code on the site if the basic one. Please email me for the one you would like.

Hi Alan!

Thank you for stair light project. It works perfectly. Is it possible to get the hex file, version 1.3 or 1.4? I tried to MicroCode Studio (MCSX) but show me an error. I have no experience with this. It would be very happy if they could get the new version.
Best regards

P. S. Sorry for my english.

Hi Alan...
I bought your stair lighting kit from you six years ago and it's still going strong. I always meant to send you the pictures from the second story addition....well...

I just got to say, it is the hit of my remodel addition...

Thank you so much for the help and if you want pics of the finished product, just let me know.

Hi Alan,

Great videos!. Your projects are inspirational stuff.
I was wondering if you can guide me with my project.
I am working on a similar project but i have limited experience. I was wondering if you could provide me some information or schematics about how to connect solar panels,computer fans, motion sensors and a led light.

I want to connect to a solar panel :

-three 12V computer fans
-eight led lights
-one motion sensor

Computer fans and lights must turn on when sensor is activated by motion also computer fans and light have to stay turned on up to 10 minutes.

Again wonderful work there!

I think all you may need is a motion sensor that has a time output needed for the shortest delay then build a pulse stretcher circuit for the longer delay needed.

Hi Alan,

I would like to use the automatic light controller for two flights of stairs (three entrances). I have a 12 Volt DC source, 100 W and LED strip lights monochrome.
Do you think your controller would work for this setting?
Is it possible to have 4 sensors instead of two, one pair for each flight of stairs?
How much would that cost and how long does it take to get the final product?
Thank you.
Best regards,
Replied on: 1:12pm 09-27-2012

Sorry this controller can't control strip lights due to their power consumption.
