Project N0NAME

...after a long time at home.. with nothing to set me back (school hours, long night drinking sessions or such ;)), i've been doing 2 things mainly:
a nice new fan controller... which works in a very efficient way, i might add.. pic time:

..this is the 4th topology i tried.. this is getting very close to what i can do right now.. schematic is from wikipedia, indirect link, but i tweaked some values and changed a part here and there.. this is a 'pulse generator' :D

i control the circuit from one knob.. the ! and by varying this resistance (can tweak it to be a linear control or even a logarithmic control :D by adding some stuff), i vary the noise/speed/cfm of my fans :) and not just one! this baby should control up to a few dozens of watts (the v3 could keep even 120W under control, but i sacrificed some control), not just 10,15 or 20 watts..

this is how it works, for those that wanna know but don't feel like reading thru hours of materials all over the net and in.. the books.. scary place..

while normal fan controllers vary the amplitude of the voltage, giving the poor fan less than 12V.. this type of control gives the fan pulses, 12V in size, but varying in duration.. so, the fan receives it's nominal voltage needs, but is allowed to take a break too :) PWM (Pulse Width Modulation) in principle, can be used as a fan controller, a strobe light driver, an ignition coil driver or even an audio amp...

..this is the controller set on low.. this means the pot's resistance is close to zero, and the other components in the circuit determine the minimum duration of the pulse.. i don't wanna have a total off position because i plan on using some other options to tweak fan speed..

..turning the knob on the higher side of the resistance side ;).. we get a longer work time and a smaller (it can never be zero, but it gets really close) pause.. this means the fan will work a lot more and move more air.. generate more noise:(

i know i've taken extreme shots.. so. i also have a nice video of the circuit's response.. i turn the speed down in this video.. hope the effect is seeable :)

what i have to mention is that, as you can easily spot in the pics, the max voltage isn't 12V, but 11+.. this is because the components eat some voltage too.. that's why, if this thing passes the prototype stage, i'm gonna have a nice rotary switch to allow my fans running in off/5V/PWM/12V mode.. i still have some doubts regarding the functioning of this contraption, as fans have a variable resistance while working.. i know it's high, but not how high :) oh, another shortcoming (at leat in the fan drive theory) is the pulse frequency.. i tried building a fully customizable pulse generator.. frequency and duration.. and kinda failed.. or at least, i didn't get the response i wanted.. it did lower the apparent voltage to 6V.. but that wasn't my goal... i wanted 3% to 97% of 11V.. and failed on th elower end.

why would i want to control the frequency of pulses? because you can hear it indirectly.. the pulses translate into switching noises from the fans ICs, which are there even if u use DC, without PWM.. the problem could get more serious, and i've seen it with the other design(v3), which i built and tested.. by varying frequency, noise is also controlled.. if i where to use a frequency higher than what we could hear, i would have problems only with animal rights activist :) but could sleep at night ;) my best design yet achieved only a frequency of 2KHz (need more than ten times this value to be in the safe zone.. >20KHz).. after i build this puppy (next week i think, when i get back together with my tools :D and have a nice long time to spare)..
oh, basically, i wanna get my fans really slow when needed and do that by reinventing the wheal to fit a larger one :D (mobos have some kind of PWM, think asus Q-fan or the newish board sporting 4-pin CPU coolers)

..the other thing i did during late nights was.. (warning, should be in the crazy idea thread, but i couldn't find one :D) this.. heat-pipe extreme...

..start of the idea.. an all fanless design.. but with the ability to turn the things cooler.. the other side is a huge piece of aluminum with fins.. design not final..

..more heat pipes..

..err m.. looked at the specs of the oo so quiet ac3 fans and surprise.. the new ac12L are even more quiet.. so i used 2 of those.. and maybe added something to the video side of the story.. still working on this.. it looks good and it should do wonders (8mm heat pipes used all over, except on the ram).. but i'm thinking is this do-able? my work-flow in max is by nature mimicking the natural way.. but.. need some critique :) if anybody likes this, i can do blow-ups.. maybe someone with the money backing would try this :) i sure would like it, but no heat pipe maker close by (i'm gonna try and mail the company mentioned looong time ago.. again)

But, is the motherboard gonna boot up if it doesn't sense a CPU fan? My computer won't even attempt to boot windows if there's no CPU fan detected.

depends on the mobo.. and there is a setting in the BIOS to allow for this (cpu fan alarm or something).. i actually did run almost fanless.. i had only the exhaust working on low.. and no other fan was running/connected.. and the case fan has no yellow wire.. so all i got was a red warning near the cpu fan rpm at POST time :) depends on the mobo, but if u think how many fanless heatsinks are out there.. and that there are water-coolers that also sport no fans at all... newer mobos should allow running nothing at all...

Only for the innovators. :D

=)) kinda came out funny =))
almost reminds me of a 486 board i had looong long time ago.. it had everything on-board.. and no fans at all.. even the ram was partly integrated :) i think intel and amd are going back to that design (integrate everything in the northbridge/cpu).. except with fans :)

hey did you draw those heatpipes if so waht did u draw them in

draw? :) if it were that simple.. i use 3d studio max... and the bends should be do-able in real life.. most of them.. the heat pipes are shapes, with an 8mm thickness, at first, tracing the 'path' of the heat pipe going thru the blocks and making contact with the radiator.. of course, to make it look like a heat pipe, i used a controlled reflective orange(copperish) color with a slight bump map :) that's how i drew them :)

ahh i get it now i think iv got that program somewere on my pc

one problem.....

for a heatpipe to work the hot end has to under the level of the cold end, so the GPU cooler would not work, and the rest of the sistem for that matter, because you are looping the pipes downwoard
think about it, the way heatpipes work is this vapors rise from the bottom to the top were they condense and due to the cold walls, and fall back down in the hot bottom end

but i must say you did a great jog drawing them

Actually, I'm pretty sure that the design of them means that hot vapor is forced through to the other end, so it doesn't matter which way up it is.

+Rep for another magnificent update.

you have a point there and i dont know that much about the subject to say if you are right or wrong
the best argument i can come up right now is this: bit-tech had a pcu heatsink test some time ago, and they made a note regarding some coolers, something like "only three pipes out of six will work, because only three of them are going up"



of to find some proper info....

:) well... gt40, you would be right.. and are in 80% of cases.. a poorly designed heat-pipe relies on gravitational force.. but, then.. it's not actually a heatpipe.. it would be more like the tube that the waterchill use.. that kind of pipe needs some form of direction, but a nice heat pipe is made of small cavities that promote capillary action >> fluid (one that wets the tube) goes up against gravity if the tube is small enough that the curvature the fluid forms is so tight, that it makes it 'crawl' on the tube's walls (the force pushing would be 'heat')... and, after reading a bit, i found out that 'they' even make 'em with ridges of some sort in some heat pipes interior walls and also add a wick! and an evolutionary development are sintered powder pipes (i don' know the exact mechanics inside of these..).. i asked and it seems they are some sort of spongey metal.. and i do know that a normal pipe has low pressure fluid inside, something water or alcohol based, but i have no idea what kind/type of coolant the sintered powder ones use..

aanyway, good (expensive?) heat pipes should work irrespective of orientation, but maximum efficiency in case of normal pipes is achieved when used in a heat-goes-up configuration.. oh, i forgot to say that this 'system' had originally a desktop layout, with the video array at the bottom, sucking air thru (somehow.. not quite decided..), and the big aluminum radiator on top.. so the mobo would be 'hanged'.. also, in this way, in case i had to manufacture my own pipes (buy copper plumbing pipes, like the ones used in interior heating), of low quality and questionable functionality (cut them, curve them, fill them with 'something' and then seal them), i would take advantage of the hot and cold orientation.. of course, with a nice commercial sintered powder pipe (i've been sending some more mails, hopefully i can get a few).. the system could be mounted in any way :)

oh, dang, i forgot about something... should have posted this earlier

1st, thanks to both of you for reading :)

2nd, i finally got some money and wanted to buy a pump.. for one of my hidden and deepest fantasies: water cooling :twisted:

so, several months ago i found a nice 1200L/h pump, AC powered, similar to eheim's products, but from a lower brand, at a local fish-stuff store. being the only model not submersible, it was perfect :p of course, faith has a funny way of dealing with this situations.. and today.. not only did the shop didn't have it in stock, but none of the guys who worked there half a year ago are there anymore.. i spent half an hour trying to tell them what i was looking for (the first guy got in one sentence), with no success :( well, i'm gonna try again when i go to school.. maybe i'll find a bigger fish-shop.. :bunny: 'till next time..

Wow those models look amazing man...what program do you use?

3d studio max, v8 sp3... there is v9 available also.. but it's pricey, 3k$+.. some kind of university program is best if u want a non-demo version.. for free.. ask someone if they can give u a copy.. here, you have to ask the right person and be a student and be able to prove that :)

hey just noticed this was ur mod likin it loads

Nocturnal iv pm u about that program

10ks

to the mod!:
last night, between 3 and 4 am, while trying to get asleep, i had a couple of 'visions' :D so, now i need the folowing:

#2 square meters of black leather or similar, artificial stuff (do-able..)
#0.25 sq. m of plexi (can do)
and..
#some copper (!?)
#drill with table (the article i read about making water blocks totally shattered my insecurities) and clamps (!?)
#a donor water cooling kit >> 120mm rad (keep other parts until i get more money)
#lots of solder (check)
#open-flame device thingy (do-able)
#time.. gonna need a month plus, till exams pass.. and i pass them too

so, a question... i can get the 3D galaxy and Tt big water (the kit with single and dual rads).. budget-wise and shipping-wise.. which one should i go for??

copper eh!! your not doin what i think you r :) also makin my own watercooling kit aswell

:D weeeellll, my heart won't let me destroy the current config i have.. i absolutely love the sonic tower! but if i can design something to get the temps lower (i have 36 degrees now.. no noise unless i turn every other thing in the house off..).. 10 degrees lower in same conditions :D.. also, i'm gonna go full out then and use a peltier.. if i can find one.. i'm googling some specs now on and see if i can design my own power supply for it :) anyways, i like my pc a lot.. gotta convince my parents to give a couple of buck.. ok, a bucket! to buy some new stuff, materials and components.. i think this will happen in the summer.. but before.. i can still play around with my own bucks :)

lol just get whatever money u can i say stuff like u still need to give me back that tenner which shes already givin me about 2 times already

Thanks sirkilla, appreciate it...and great work dgrmkrp looking forward to seeing more

Hi everybody :)
Got my hands on a 5MP camera for a few minutes.. and it's cable :D
Got this out:

case.. with markings..

my sleeving and cabling..

another shot..

night shot... hmm... not much..

my night light, under the desk.. yep, it's a light from an LCD :)

..the inverter

..old psu, amplifier and it's cooling 'solution'

..front end..

.. i'll hopefuly get more pics when i do more stuff :)

Glad to see you got a new camera, but you need to pull back a bit from stuff you're snappin! Can't tell what some of your stuff is! :)

-Dave

@DaveW: sorry, the camera acts a bit different than my phone :rolleyes: but i'm getting the hang of it.. never used it before and.. it's not that complicated, but i have no control over zoom and i'm actually taking the photos from 30cm.. cause if not, i would have been forced to reposition the stuff... well, next time i get my pc open, i'll shoot more stuff, and be more careful:D

the unrelated stuff is under the table i keep my keyboard and screen on.. there is a 12" woofer there, not used, that acts as a support for my pioneer amp :) the cooling i rigged there consists of 2 8cm /5V led fans connected to the (hot-wired) psu i used in my computer a long time ago.. also, for convenience and 'eccentricity', a CCFL tube is taped under the table.. i can put my keyboard on my knees and type at night.. if needed.. or study :)

more pics.. i've been toying with the macro feature, but now i see the importance of a tripod.. or a rock steady hand :)

mouse pics this time:

..the flash makes everything shinier and i can't see any flakes with my naked eye.. !?.. well, i have to learn how to shoot these scenes.. it's kinda harder in real life.. than in 3D :|

..'day' shots

..night shots

.. the first pics show that a steady shot is impossible right now :) i'm sleepy and can't focus myself.. and the flash is over-powered.. :)

..till next time, happy modding

You need to extend the exposure time and get a tripod. I actually wrote a photography tutorial, but i need to find it...

...ach, it's in a folder with the million other things i've written and not posted. Just too damn busy these days.

-Dave

i thought of that.. but all i can find in the menu is is the iso setting.. and an EV setting.. hmm... i should toy with them.. i know a bigger iso is for darker shots.. i read some articles on tomshardware, but i guess i just didn't need that info.. till now :) well, more exposure and a tripod.. hmm.. no tripod.. will improvise :) still, i have to hand write 150 exercises and half a note book of courses.. damn time... i wish i could overclock myself..

Well, like i promised, i fu..dged another exam.. grrreat... so, i bought myself a new mouse :) i had an a4tech x-710 and now i have a x-750 (laser, 2500dpi :D)

..mouse in the .. nope, box and mouse out of it :) notice the nice under-belly..

..i gave my other mouse to a room mate and i got his in return, to mod :) this is the stock version..

..mouse disassembled

..starting to glue leather..

..trimmed version..

..after some fine cutting and gluing and cutting..

.. here's some potential.. i have a thing in mind :)

..how it looks now, after i ran out of glue.. hmm... till tomorrow..

nice mouse you got there

that is theexact mouse i have, main is red

a4tech thing, right?

10ks.. yes, it's an a4tech.. which one do you mean? the blue one? or the black one ;) :)

back to my crazy mice mods..

the victim.. the "gold-plated" connector.. comparison with normal usb plug.. nice surface and logo - will soon be gone..

..triple fire button (3x click).. side buttons and side grip.. i will try and keep the side grip as it's nice and rubbery and does its job nicely..

..mugshots of the victim..

..the laser sensor and the stuff on the belly..

..front to back and a nice foot pic.. this model uses black feet, as opposed to the white ones used in other siblings..

..dismantling and checking cut-ability and mounting system..

..frame and weight.. same model as in my other mouse (x-710), with the same x-708 (ancestor) marking.. 18 grams..

..guts 1.. laser diode and it's small circuit.. roomy design.. just some caps in my way, but doable.. again, lots of room with nice and neat organisation and button placement..

..guts 2.. the bi-color diode (will be replaced with 2.. red ones.. maybe), more markings and birth date.. laser from side... small height, perfect for what's next..

..top part and ... lower top part..

..mask/markings for cuts.. ignore the 'dots', i have..

..ta da.... . ..ta.... da... ta da..ta da..tada... (jaws theme).. stuff i was planning on using with the dremel on the poor defenseless mouse..

..usual leahter works.. this time, i'm thinking on something more refined.. so, lots of glue and sanding will go to waste to achieve a plastic integration.. with the palstic... errm... hopefully, you'll see what i mean..

another was sleeping..cutting work.. i used the soldering gun to melt thru the plastic and then a sharp cutter to sculpt it to the desired form.. coouldn't use the drill cause it broke - a room mate stepped on it.. he was ok.. (for a while at least..) and another was (is) asleep, so, no noise..

..this leather, although from the same patch, is different than the other one i used.. so the model is different.. the pics show how rough the cuts are.. need a lot of glue and sanding to make the 'grills' look good..

..i've taken out lots of material inside to make room for the fan.. haven't got it, but it should arrive on order.. a 30x30 or 35x35 or 40x40mm fan, native on 5V.. from sunon hopefully.. 5 of each for nice experiments.. and for other mice too...

comparison with old mouse.. younger brother... older build.. hmm.. weird.. the x-750 is slightly bigger, which i don't get.. as there is room inside, the circuitry wouldn't require a bigger housing and the added cost of another set of molds.. aaa... never mind :)

that's it for now, i'm gooing to sleep.. i'm gonna need some cash to buy like 35 grams of super-glue and some leds.. will check my stash.. i'm planning on making 'side skirts' of leather too.. and lacquer the remaining plastic piano style.. and make an inside cover for the electronics .. and add some filters in intake side.. a chromed wire mesh will do this trick.. the theme is black and red.. the output is over cut and needs some reshaping.. also, 2 more slits have to be cut on the last layer, thru the leather, cutter has died.. mm.. snapped :|

till now i've spent more than 12 hours on this.. but it was worth it.. i think i'm not even half way though.. so, yesss, i have hidden plans..

oh, because the mouse has no native lighting, i guess i could make it any color i want.. if you think blue is better.. post :)

..continued.. after another day of work i have kinda finished the external body work.. now i have a real wide-body kit.. not only was the mouse bigger than my last, now it's 2~3mm bigger in all dimensions.. i lost some blood and my head hurts (hunger or rum may have something to do with this..), but i am a tad happy and maybe even proud of myself.. pics:

stuff ready for further mayhem.. that's my phone.. k300i... it can do nice shots with proper light.. or maybe not..

work bench..

side shot.. the side intakes are being sculpted by adding a layer of super glue to toughen the leather and then sanding.. repeat until i get a rounded, cvasi-organic form, not to symmetric, not to weird.. something a bio-mecha mouse would 'grow' to adapt..

..closer shot.. still can't focus right.. i need the flash, but it's not available in the macro mode.. so my handshake blurs everything..

shots of the wire-mesh installed from the inside structure.. i used the soldering gun to heat the mesh in some points and pressed it against the mouse.. it liquefied and bonded..

more shots.. the intakes have chrome mesh and the exhaust has copper mesh.. looks nice.. and with some lighting.. <??>

..blood shot.. i heal to fast.. i'm wolverine's cousin... :D but i shed some blood.. you can see how blood trickled to the back side, flooding my nail..

..top side.. under construction still..

..compared to the first version..

..another shot...

..more.. more side intakes, on both sides hopefully will assure more airflow..

..more.. i have to do something with that weird thing i bet you can see near the 3xfire button.. i had to do it like that because the top-most layer wouldn't fit.. not even the stock did that well.. they chose a very weird mounting mechanism..

..more.. hopefully the new 'design' of the vents will make it stronger.. i didn't wanna make them wide and with small struts.. looks interesting.. don't like it 100% tho.. have to experiment more..

..more.. you can see the only stock remaining part, although it has been sanded to remove the markings for the speed changer.. the middle section will be kept like that, cause it works best IMO..

..more.. see? it's not just the perspective.. the new model is bigger..

..more.. weird... the older is blacker.. hmm.. need black die paint and can't find it..

..more.. by extending the leather area i hid the side buttons and will hid further mods better.. this is like a tank.. no more sports car.. i have a NOS escalante :D

..assembled and buttons tweaked to .. work.. when building something up, like thicknesses, it's nice to check and tweak.. i don't want a leather piece of furniture.. i want a functional mouse..

maybe is should paint everything black? some acrylic and die paint? hmm.. still possible..

..slit made for the switch that will control the fan.. man, i have so many ideas to go with the roomy inside: resistors, fan, fan control?

..because i'm dead tired and hungry.. and my head is killing me.. i'm gonna end this with a cheap, fast .gif of the before and after kind :)

hmm.. on second thought.. i still have to sand some more, to get the lines close as possible to perfection.. night..

what program are you using to make the .gifs i love something like that

errmmm.... the frames where made by varying the opacity in 2 layers in photoshop, then i saved each frame and made an animation using a free downloaded gif thingy>> barbarosa or something.....

hmm.. i am just starting to delve in the wonderful world of electrotechnics... yey! for an exam.. buu... before, that, i forgot to post a ghetto style mod.. well, not a mod.. but ask yourself.. if u have cd cases, duct tape, carpenter's glue and lots of ..errmm.. pinkish paper.. what can u do with them? oh, and i forgot, thanks to a friend, i have a hole in the window too... so? i had an idea..

hole in the window prepped..

case prepped..

forming the duct...

after drying, i now have big temps in my room (>30 degrees centigrade) and ~25 degrees for my cpu.. this with 5v >> just some cool air entering... in silence.. and with improper positioning of the heatsink's fins.. (i'm studying to change that..)

:D

edit1:

..can't go lower.. dammit.. will have to take voltages lower... i have all fans running on max now... hmm... the fin alignment would take temps much much lower... #@$%@.. i wanna go sub zero... :(..ok, rant over.. i'll quit experimenting for tonight, as i don't like noise.. uu, i just hit 18 :)

edit2:

:D :D ..lower...

man you are going to suck bird in triugh that thing lol

great idea, but won't it cool the room too?

how much did you pay for the x-750... ou, and i have the blue one

ROFL.. that's what my room mates said.. "you're gonna get feather inside your case man! don't do it"... but if u look closely, there is a copper mesh installed.. i have nothing with lil birds that might get caught.. they never bothered me so i will try not to distress them either :) (but in the summer, during summer exams, there are some type of owls that can't quit singing at night.. no comment.. woooot... woooot... )

well... considering i'm really in need of cooling too :D another +... this guys are crazy! they are pumping heat thru the heating system to drive us out, i think =)) so, we usually have to open the windows, cool down, close them.. repeat :) i just turned the fans down and stopped one.. now i have 32 degrees... and silence.. :) i love silence..

ahaaa now i see it, tha damn thing was so fine i thought its cardboard or something

ok, for this installment, i shall continue to mod my mouse.. oh, my nice old crt tube passed away so i have to switch between computers and sometimes use the adjacent screen and plug it in my pc.. :(

on to the pics:

the window side of the room, with visible computers and displays.. i would say this is a nice example of space management... looks a bit different now..

..dead screen... or a new kind of kit bashing project :P

friends pc.. covered with white/transparent plastic panels and with 4 ccfls...

..his mouse, in building stages.. silver after 2 coats and sands.. black is cleared with about 5 coats now, still not happy tho..

..leds i was playing with.. i have about a dozen.. red, green, yellow.. from keyboards and cigarette lighters.. and some laser diodes we are playing with.. i wanna try and do the predator gun :D

..some stuff i got out of the dead screen.. lots of resistors, some caps, some transistors.. most i can use, some have been charred or the legs have been cut too short.. by me..

..old pic of body work i did to the mouse.. gonna have a new session of sanding soon.. still, i'm taking a break right now from learning.. so not that soon..

..close-up of the mesh i used inside.. this is from long ago, just testing it.. although it's final now, i refined the slits more.. and will repeat until i'm satisfied..

electronic work and analyzing my possibilities...

some pics of the leds.. i'm going all blue with this one.. the top 2 leds are connected to the color changing mechanism that informs me of the mouse's sensitivity (different intensity leds are used so i can tell a lil how much speed i have.. and at which step i am).. bottom leds are connected at different points in a diode series circuit, so that i dropped the voltage without using resistors.. this i did before i had lots of spare resistors from my now dead screen..

dark shots..

.. i painted the insides of the mouse white after covering and insulating all wires.. i left the wires that will lead to the fan longer.. the paint diffuses the light a bit and gives me a base to work with further.. i wanna paint it with some blacks and grays.. or not.. i don't know et..

on another plane, it seems another pack of ordered stuff is gonna arrive soon:

..for the chipset.. more modding involved as i don't know how to integrate this in my airflow schematic.. for best performance and stability.. but i have some ideas..

a nice fan control.. not needed right now, but why not? :)
i wanna build my own, but this is gonna offer me a hint on what they use (commercially) so maybe i can build some similar stuff, with better components >: )

for the ram: copper headt-spreaders :D.. errm.. hopefully for some new ram:

corsair ram :) 2x 512MB ddr 400, cl2.5 :) good enough and better than what i have now :)

okay.. enough.. ishould log off now (literally, i'm very sleepy..). bye

hmm... because i use the pc mostly at night when others are sleeping, i seem to have missed this.. sorry.. i payed about 25$,but i found it at 23 too, but was out of stock.. up to now i spent about 5$ on super glue =)) and the leds were free..

well, i'm back... exams finish the day after tomorrow.. too much too learn.. need a break :D

pic time :

got my ram heat spreaders

and installed them..

got two silent fans to replace 2 of my own.. they are recom 120mm, yellow uv blades, 1700rpm@19db.. so they say, of course.. they are quite silent (not like ac12), but move a lot of air :)

go this fan too.. enermax with variable rotation :) gave it away as a gift :)

..with this lil mod: a gf5200 with a zalman north bridge heat sink :)

also, we washed out heat sinks :) funny =)) lots of dust there, too much!

fan controller installed and working nicely..

..some uv action :D

oh, i removed everything cause i put zalman paste all over my chips :)
till next time..
