i know i'm going WAY off topic, and really great modding idea btw, but you can buy an xbox usb controller adapter, and download XBCD drivers, and that way you can avoid all that trouble of putting an xbox port there. i got mine at www.liksang.com
just search xbox usb adapter and you should find it no problem. i got 2 of em, and it's great for emulators and sometimes FPS.
THE CASE LOOKS AWESOME! and i agree with putting those cones on the fans so it looks like jets n stuff..... (i dont know much about planes)
FPS on joypad??? Are you insane???
Anyway, the Xbox joypad is a usb device (well two really). Even the colour of the wires are the same (there is a yellow one extra on the Xbox). Just trim that yellow one back, and hook up the leads exactly as you would for a usb port. I did, used Cuxctrl, and I have 2 Gamester Arcade Sticks on one PC in the front room (for Mame), and one on my main rig for loads of stuff (BUT NOT FPS!
). A grand total of 89p (plus cost of the controllers).I can't vouch for other controllers, but the Gamester Arcade Sticks suck 400mA and do work (but more than one on a hub requires extra power). The Logic3 Arcade stick does not work (untested with a powered hub).

That's amazing! I can't believe you wound your own transformer... I would never try something like that. Looking forward to more progress updates here.
you wouldn't happen to be from New Zealand would you?
seriously though, that thing is freakin crazy. only bad thing about the design that i can see is that you are going to get a lot of cross wind with the blowers firing directly at each other.
but ya like others yave said, you are [H] to wire your own transformer. don't quit though, i need you to finish this project or i'll die.

nice fans just make sure you don't put casters on the bottom of the case or it will pull itself along. could be interesting though...
good luck!

Wow, didn't think those things could run on such a small circuit - the other guy with those blowers originally (@ocforums) had a PWM controller that was much bulkier.
Other than that, its looking great so far. If it turns out half as good as that picture, you'll have a great case.

Ok, so Im experiencing a small technical difficulty. As I was warned by another forum patron, the PWM circuit is causing a horrible buzz with my fan motors. So, Ill spend the next few days researching a solution. Until then, I have started on another blower related mod that I think is very unique. Im still working on the details so I wont reveal the precise nature of my latest feat of hackerjackery. Instead Ill post a pic of the ingredients and challenge you to deduce what concoction is a brew. The first to get it correct wins 1 free transformer winding...w00t, I guess ???
Hmm, what is he up to???

volts + amps on each blower (duh) (dont forget you cant hook thos up directly!!)
and the parabolic mirors... on the ends of the blowers? spinning? oh that would be too cool
and for varing the motor speed... VAC transformer... IE Varable Alternating Current... basicly has a moving winding to change the output voltage.

I commend you on your performance so far. I can't wait to see the finished product.

First, a great looking mod/design.
Second, as far as voltage control goes, couldn't you use something like what is used for race car sets. The ones that look like guns. I believe they just use a coiled wire to control the voltage with a slide to control how far along the coil the electricity has to travel. Voila, instant volt control. At least I think that's how they work. COrrect me if I'm wrong.

AFAIK that is a resistive system, like a good ol' potentiometer, where the unneeded energy is basically given off as heat. Not a big deal with little tiny race cars, but with those monster turbines... meltdown?
Anyway a PWM circuit is by far a much more elegant solution, and wastes a lot less power.
Maximum fun is important, but don't dismiss this too quickly. A hand wound multi-tap transformer for speed control will be:
· a modding first AFAIK (PWM is old news)
· by far the most efficient way to control voltage and fan speed
· foolproof (definitely no humming)
· cheap (except for your labor)

wow, this looks like an very helpful read. thanks alot. However, if i end up buying an osciloscope because of you i'll redirect my girlfriends hollering to you PM. * heads to office to dust off his trig*

Wow that was an excellent read. and I noticed that rondu. I'm hoping i might be able to adjust the cap values to compensate for my greater load. I tested with a 220uf cap and that eliminates the motor buzzing but i could fry a falafal on the mosfet because it's trying to discharge the cap at low duty cycles. So i'm off to find some < 50uf 100v caps and i'll let you guys know. Thanks again blusol

Ok, i've been working on the pwm circuit all week and i finally got it COMPLETELY silent. The pdf blusol gave me was excellent so i passed it by my pwm guru Gary, who recommended some modifications for the 3 amp blowers and, Wham, it worked. I used a 1.0uf mylar capacitor and a 1k resistor. The only issue i'm now left with is my mosfet on which i could fry chicken if i so chose. So it's off to the junkyard to find an old stereo with a giant heatsink.Stay tuned for i have an interesting new mod i'll be posting.
Ok, I had a discrete Mathematics and Algorithms and data structures test in the same week and a birthday on tuesday so Ive been a bit occupied, hence the absence (got a Dremel 400xpr from the honey :-p ). Nevertheless, work has commenced. Lets see, where were we. Ah, yes. Thanks to a very clever paper I read on pwm noise reduction and some very helpful assistance from Gary my pwm guy, I was able to modify my circuit to the effect of eliminating nearly all the audible noise. Its a very good read if youre interested. It was presented to me by blusol here at hardforums. Here it is if you so fancy a night of tinkerin with sinusoidal functions...and who doesnt. Next weekend Ill be making the circuit board for the pwm, Ill be running stress tests on the circuit till then. In the mean time I began construction on what Im calling the blower health panels. The panels are essentialy four heavily modified panel meters mounted in 45 degree recesses on the top left and right of the case. These meters will monitor the current draw and voltage of the two blowers thus giving an indication of their relative health. If one motor begins to fail the panel meters will begin to take peculiar readings and Ill know its time to replace it.
My profound apologies for having to subject you once more to my illustrations, but I must post this to give you an idea of my concept. In the final manifestation Ill attempt to round off those harsh edges with some body filler.
The pictures I posted earlier of the mystery mod ingredients should now begin to make some sense. These are 2 blind spot mirrors I got from AutoZone. With the mirror removed they make an excellent housing for my meters.
I used the circular mirror as a trace for the piece of plexi that will form the meter cover.
The plexi was cut using with a metal grinding bit then ground into shape with a stone grinding bit. I had to use this peculiar mounting for my rotary tool in order to properly grind the edges. My 400xpr doesnt get here till Thursday, it comes with a circle cutting kit.
Cutout the hole for the uh...meter guts.

A pic of a disassembled voltmeter.
I shaped the rear housing out of the old panel meter housing
A paper print out of the test façade for the new meter.
A test fitting
Here is a closer look at the nearly completed test meter next to its former self. You cannot quite see it in this pic but there is a plexi shield on the meter. In the final product I will paint the black casing and paint a mask over the area of plexi showing the uhhh...meter guts.

Here are the four current full color designs for the panel facades. They will be printed on a high quality stock with a very high resolution photo printer.
Ill be finishing the rest of the meters when my Dremel arrives as to take advantage of the circle cutter. I thought this mod might catch on so Ill be willing to write a more detailed tut if anyone needs. Till then.

rofl, meter guts.
Those decals for the meters look rad. I was skeptical of this mod when it started, but you definitely got a good head on you to make this mod so
btw, you're taking some pretty advanced math courses. Algorithms are used a lot in programming, right? What do you plan to do for a living/what do you do for a living?

Thanks for the compliments. Well, technically algorithms are used in everyday life. an algorithm is just a step by step instruction set for solving a problem. In computer science algorithms tend to inherit a mathematical manifistation but they don't have to. I'm a computer science student now and I run a small bussiness called the digital self (thedigitalself.com) through which I design web applications for clients. When I finish school i'll prbably turn the digital self into a mathemetics/computer science reaserch firm because I think I'd make a better scientist than a business man. I also think id make a better fry cook than a scientist but that story is for another day.
