This will help you make those little somethings like home made fan speed controls, etc, that you have to put in the PCI bracket space.
I FINISHED the fan speed control at last!!
Here are the dimensions for the PCI bracket along with a picture(poor quality, sorry:shadedshu).
(no, the scientific calculator at the top of the pic wasn't used, i used it as a paper weight)
all dimensions X are along horizontal(along x-axis)
all dimensions Y are along vertical(along y-axis)
total length from left to the dotted line is 13.2cm.
X1 = 6mm
X2 = 3mm
X3 = 1.6cm
Y1 = 1.8cm
Y2 = 9mm
Y3 = 2.0cm
*The dotted line is where we turn the part on the left at right angles, while pulling it toward us....get it? its faintly visible in the pic.
Here are some pics of the aluminium bracket I made
The bracket after cutting out:
Cutting out the screw hole and bending it:
This is the cover that guards the opening:
i bent it in half and stuck it to the bracket to reinforce... You may stick it without bending in half, though.
the final result:
only fixing the potentiometer is left.
Here's the package of my test circuit. ALWAYS REMEMBER TO FOLLOW THE GOLDEN RULE OF TRANSISTORS: INPUT THROUGH BASE ANN AMPLIFIED OUT OF THE COLLECTOR.
Its time to move on to the real deal!
This is the layout of my printed board circuit:
notice how the two individual fan controllers are simply copy paste!
This is the circuit nicely soldered on a piece of 24 pin print board.
After attaching the output jacks for the two sets of fans, the potentiometers and mounting them on the bracket
and ...... ACTION!
Does it work??
Yes, yes it does!! And that too for any load you put across it. This means you can run with multiple fans in parellel!! This controls fan speed between 100% and 25-30%.
THIS is the best way 'cause it cost less than $1 for the whole thing!!
Only draw back is that for 2 or 3 pin fans the speed control isnt uniform, but on the other hand, not enough to notice
LED UPDATE:-
The LED is basically connected to the fan(s) in parallel, through a particular amount of resistance (or else the LED will(may) burn up).
Here's how to calculate the resistance using ohm's law.
first lets say your LED is rated "v" volts and "i" amperes.
so now i've simplified a formula for you
resistance = (12-v)/(i+current rating of fan)
another EDIT:-
For insulating the underside of the PCB, you can use your mom's or sis's nail polish. easy to apply and easy to remove. + this is better than Liquid electrical tape!!!
njoy!
ps:- dont forget the thanks!
