Project N0NAME

@Lairy: 10ks and that is a nexus 4 channel 3,5" fan controller. I had to place an order for that and it cost me almost 30$.. But I liked it as a temporary solution :) It is fairly powerful and compared to the akasa model I also own, a tad more resilient (I managed to burn one channel there). It has a fairly long PCB, so it is almost as big as a floppy drive.. but, looks nice.

@The boy 4rm oz: 10ks, but.. well, I didn't plan that.. I need some mesh to cover the mobo up and use my highlighting scheme.. Also, a UV board from DFI Lan Party series would be much cooler :)

I just received my DFI LANParty (680i LT) this afternoon. looks awesome under UV light.
Here's a pic:

OK.. creepy j/k :D
Looks so awesome! But you know what it lacks? The AM2 retention module ;) (I like good CPUs, but I kinda favor the one who loses >> AMD :) )

Well all of the water cooling components I want have just come back in stock so you will be able to see my other UV components soon. Check out my worklog Project LEXA

I want that MoBo.

Where?

How much?

I want it.

Post it to me. Please.

I'll pay the postage and everything.

Sorry, I'll stop drooling now.

+rep for giving me movement and everything.

Lol no problem mate. I got mine for $399.00AUS, They wanted $480.00 but I said no more than $400.00 so they gave it to me for $399.00 lol.

Ok, the board looks nice, but at this price :( :( I could never afford it, considering that it would need a processor and a video board too.. :( Luckily, I'm broke right now and the current job I'm doing will pay me just a few bucks (designing stuff, but not payed by the hour >> by the amount of accepted projects.. currently I have 6 running and waiting for approvals).. So, I don't have to think about it :);)

One thing I can do is take a break from the chores, the learning and the physical world and design nice circuits.. or better yet, refine them :)

So, here is what I made:

These are screen caps. Please ignore the weird names I gave, they will help me in the board creation stage. I added and tweaked a bit at the output stage, preparing for a LED, after uploading the images.. so, this is the fan control I have been talking about for such a long time. I actually made a prototype, but because I'm not that good with a soldering gun and I used a bad board for my needs, I ended up recycling everything on the board, except for the final transistor.. Well, that was an older design, not truly suited for my needs.. now.

This circuit is based on the Pulse Position Modulation principle, has a nice over-current protection section and a low voltage drop. I tweaked the schematic to get from 9V to 11.2V bursts. And increased the current by the same rate. If anyone is interested and can find something wrong, I would like to hear it :) I could build this and find out it doesn't work either :( And this time, I'll be buying more stuff (gonna make a 1 or 2 layer PCB.. so I need copper boards, chemicals, a small drill head.. a black marker or press'n'peel foil..)

Some chronographs too:

Fan(s) is set to go at max... Because I am a dope still, this is as far as I can go.. Not 12V, but close. Not at all the time, but close. :)

Fan(s) at 50% setting

And this is the lowest voltage/current attainable...
All these pulses are 40KHz (40 thousands times per second), so IF you average them, this is close to 0V. I chose this frequency because it is much higher than the human hearing limit, but I can't tell a thing about the interaction with the fans themselves.. Till now I couldn't find one internal schematic of a fan motor.. I may have to do it myself, but reverse-engineering something this small... must wait for my new glasses :)

Finally, the part that has most worried: the PCB. The traces may be too fine and then I'm in trouble.. More stuff later :) bye

My brain hurts.

Same haha.

Sorry for that.. I can make some simpler fan controllers and explain their inner workings :) This could be nice for those that want their fan controller on the cheap and have 'em really custom :)

Happy post time! I just got my international card from a local bank, charged it with my earnings for my work (graphics of course) and have ordered a nice peltier unit :) it is a 40x40mm, 10A max, 15V max unit, which could lower temps with almost 70 degrees.. Now, I know just a bit about peltiers, but at the 15$ I'm spending (If I'm lucky, this is a 2 hours job) including shipping to the far corners of Europe.. I think it is a good deal. Only problem is this is normal mail, so that gets me worried...

Also, I'm looking around for a good chipset block, but I'm having troubles here.. found one cheap, but ain't sure of compatibility.. More on that later..

Back to the worklog.. All the new stuff I learned from other small stuff I did made me a lil bit more courageous, at least in thinking. So, these are my thoughts:

Using the antec case I have, but cutting away the front racks.. and faceplate, this is what I came with. The rest is the normal config I have (mobo, psu, top rad), except the small rad is in the front now and I have no video adapter nor north bridge waterblock.

why would I chop a nice case like this? To put 2 120mm fans in front, of course ;) Using 2 of these in the Tensa case, I got it really silent and acceptably cool at 5V. So, this is just normal evolution...

I want space for a big video card and maybe even 3 more hard drive.. You never know.. I might need/buy some in 2 moths time ;)

lots of fans, but undervolted I bet the pump will be louder ;)

Hiding behind the bays are the pump and the reservoir, almost like now.. I have enough tubing, almost all connectors and lots of fluid..

Now for fabricating.. Steel or aluminum sheets will be bent and riveted to create this tower, stretching from the bottom to the top, avoiding fans and drives and what-not..

This is what makes me feel cowardly and afraid >> the front panel.. I don't really like this simple look, but the side intakes stay. This is doable with minor bending and shaping.

This is not final, but an experiment... I could do it, sooner or later (this month.. tensa case.. or the next.. vacation). Just need some metal sheets, which isn't expensive at all..

Back to reality, I bought some more clamps and a file pack to help me with future gluing/metal working.

See you later :glasses:
