Ok, first a little background.... I did created this 'monster' about 2 years ago but never got around to posting pics for it. (yeah i'm lazy) I started this project really to learn some stuff about electronics and to have a little fun. It ended up taking me so much longer then I had hoped its not even funny. Many of the problems I ran into was because i was trying to cram the entire thing into one 5 1/4 drive bay. Finding componets that fit in the thing took forever and caused many a heartache. I wanted to make a 'fanbus' that was different and interesting. I decided I wanted one that displayed the voltage that was actually going to each fan in a digital readout. What I ended up with is a fanbus that uses a basic LM317 voltage regulator to adjust the fan speed and a digital display using 7segment displays and a 7107 analog to digital converter. I think the result is what I was going for. Let me just say that this thing took WAAAAAAAYYYY longer to build then I even dreamed. Much of which was because I was a total electronics n00b when I started it. Trying to fit it in the drive bay was a nightmare too. Becuse of space limitations, I had to use really small 7segment displays that were a pain to use and also quite spendy. Ok, enough already get on with the pics.... Here are some pics of the circuit board that I designed and made myself. Here is is after components are added.. Here is the board with the friggin tiny-pain-in-the-ass-to-solder displays. The drive bay 'case'.... Without the displays hooked up yet.... With displays hooked up... finished It was actually really hard to get a picture of how this thing really looks. There was a real problem with glare on the front from the flash. Its hard to see the display readout in the pics but it looks great IRL. Also, I know it looks like there are a billion wires all over but it fits quite nice actually. (yes it did feel like i soldered a billion wires). Each channel has a switch that can be in one of 3 positions: Off, full 12v and variable with the regulator. Also each one has a bicolor LED that indicates which position the switch is in. I will try to get a picture up of the unit in the case as I haven't taken any pics of that (did I mention i was lazy?) I an going to start a new case soon as this computer is a few years old now and will be doing a much simpler version of this for my new project, I have more room in this case. It will have just 1 channel in each bay but will have more 'eye candy'. I will post that case in the projects section as soon as I get anything done as I and just planning now. Anyhow.... thanks for looking at my little 'diversion'. Oh.... and guess what.... It works. EDIT: Electronics wizards: I am no super genuis when it comes to electronics, although I learned a lot doing this over the time it took me to complete.... I may have done something realy stoopid and not even have know it, so be gentle.
