    Black Shiny Silence [updated] baybus led indicators developed

    Since the goal is to make the PC silent (and it already is pretty silent) just having 2 touchbuttons on the front of the PC isn't enough, one has to see the setting the fan has, because one cannot hear it. I took this in account when developing the PCB for the fan control, i made a 'sense' pin wich i can connect to another device.

    Today I made this device on breadboard, to see if it works.. and it does :) It's a fairly simpje device based upon a LM3914-N chip.

    Here's the total setup:

    To show how good the QT160-D sensors work, I taped the sensors under my glass desk. The glass plate is like 1 cm thick:

    [​IMG]

    And heres a movie of the thing in action:

    DivX, ~508Kb

    note:
    the led indicator is in 'dot' mode here, I can also set it to 'bar' mode in wich case it'll display a bar of leds that fills when the fan speeds up, instead of a dot (duh)

    note2:

    right now I only have one fan connected, and one led bar. The PCB you see has 2 controllers, so in my computer i will control 2 fans and 2 ledbars with it (4 sensors).

    Since I used an IRF520 MOSFET for the final stage, this controller is able to handle up to 9.2Amps (!!) per channel, so I could place like up to 45 fans per channel :p (yes thats overkill for ya)

    OMG that's amazing.

    I don't really have a need for a quiet PC as i always have music on (even when im in bed :eek:)

    I need to get reading up on all of this, very, very impressed :D

    Well done

    Ah, i thought nobody found it really interesting.. anyway i have since designed and etched the PCB's for the leds/sensors, so basically the baybus is complete. Will post pics of that shortly.

    Haven't had to much time to spend lately, so project is going slow..

    not interesting??? are you mad...imho this project is one of the top three on bit-tech (the other two are Narcissus, and Metaversa)

    Thanks for the encouragement, but now you're grossly exaggerating.. there are lots of better projects around, like the ones mentioned, or the truck, or the project grandiosa, the reactor core, Qbix watercooled cube, and so on.. tons of them.. only thing i modded so far was the fan hole and i designed a fan control circuit.. nothint really special, the watercooling stuff is all stock.

    But.. it will get better :dremel:

    I def want an update, the touch controller looks pretty sweet and any info on what you used will be greatly appreciated. Plus I can't wait to see everything implemented as it is pretty advanced. Keep posting the updates :clap:

    Totally star trek :D

    you know how to make a chip control a fan, directly wired into the magnets so i could spin forward or reverse?

    Good work, cant wait so see the finished result.

    very nice project you have going here. Keep up the good work. :rock: :rock: :clap:

    BTW can you show a photo of the back of your case because I can't understand how it works with a 120mm radiator and "the back of the motherbord" (the connections ) How do they coexist there????

    (i hope that you do understand wath i'm saying, because english and me....)

    Grunt... please please please!!!! Bring back the updates on this!
    I am such a noob when it comes to circuit design and electronics...

    I an RAVENOUSLY reading this thread, and loving what I see!!!
    Keep up the inspired work!
    I have been considering a touch pad of this very type for my machine, so I am GLUED and subscribed!

    Wow, grunt, great work!

    I wanted to create a controller for my cathodes, LEDs, and fans, all in one, to fit in a CD-ROM case. You have no idea what kind of ideas this has given me!

    When you desodered the wires on your PSU, did you just desoder at the base of the wire, or from the bottom? I need to do this as well, but I don't want to botch it.

    And what program (and where can I get it) did you use for the PCB? Eagle something?

    The PCB CAD software can be found here. I've been tinkering around with it and it is quite good.

    Keep up the great work, I wonna see how this turns out. :thumb:

    That's a nice schematic there, hope the author doesn't mind you hotlinking it :wallbash:

    Nice work though, keep it up ;)

    No, Langer's right. I think your project is very promising (and I built Metaversa, so I should know! :p ). The home-grown electronic baybus is great work! :thumb:
