I just had another member email me regarding the fan circuit I built from this thread:

http://hardforum.com/showthread.php?p=1039857972#post1039857972

I figured I'd post it here for everyone.
The images are huge, so I've just linked to them so you can have the full detail versions.

- Top View


- Bottom View (changed the layout twice while putting it together, hence the mess.)

Hope this helps!

hi, a bit late, but thank you for the pictures ;)

now i have some time to answer.

could you provide a list of the used parts?

Just grabbed all the parts at a random RadioShack I was passing.
Meant to keep my invoice for exactly this reason, but looks like I already shreded it.

Wire. I used a bunch of wire from the original fans to get the signal out to the motherboard, the rest I already had. Probably 20-22awg.
The reason the signal wires jump in-and-out of the breadboard is to add strain-relief so the wires do not pull directly on the solder joints.

Have fun! :)

Will definitely be saving these images and rebuilding this in NI Multisim for myself at a later time.
