Speed simulator for racing games or coaster simulators

a simple project, a fan is going to blow air into your face according to the in-game speed. Easy to do and funny!

Step 1 Disclaimer and what you need

hi!

first of all the disclaimer:

***Disclaimer*** The following is for informational purposes only, I take no responsibility for what you do with this knowledge.

---

it is just a prototype in the pictures, i did not care the welding and soldering so its a bit a mess. :)

---

what you need:

- 1x DC-Motor 10 or 12V (10 is better)
- 3x 6A diodes (in my case i needed 6A diodes, you will select yours according to the power of your motor)
- you can use a diode-bridge instead of the 3 Diodes.
- some meter of wire
- 1x old Hi-Fi.
- 1x switch(optional)
- 1x plane model propeller

hey what is hifi

[Hacker95XP]

Ma questo bisogna connetterlo all'uscita audio del pc?

[tzaq93]

Hi ! Nice tutorial but i don't understand how to connect the motor to the pc? does it work if i connect it to a 3.5 jack and then plug it into the audio card? if this is correct, i think it would be posible to connect it even to a mobile phone that has a 3.5 hub? a hi-fi = a sound system? or it means nothing? i see that in the second picture you've tagged a shadow with hi-fi.. :|

[sharkyenergy]

hi! thanks for the comment! DO NOT connect your motor to the soundcard! it will most likely kill it! you need an amplifier. there are several kinds of amplifiers, even a car amplifier will do. but it is much easier to use a comon "bedroom sound system" that has a line-in. basically what you do is connecting your soundcard output to the line-in of the amplifier. then you unplug the speaker wires that are plugged into the back of your sound system, and connect the motor instead. if you have further questions just ask.. :)

[krapu]

there is a problem, this stuff only works with the sound... if we play to a car's game, there is always sound, so the modulation of motor is always at the max...

[sharkyenergy]

not esactly.. this works with teh volume.. so the more sound, the faster it turns. if you are driving faster the motor of the car is louder, and teh speed of the fan is faster.. :)

[A.C.E.]

this would definately work with x-plane because you have that freaking annoying roar, but that is usually why i switch to the outside view just to make it shut up lol. and outside is where the wind would really be maybe if i got real close to the plane... well whatever good instructable 4.5 stars

[sharkyenergy]

thank you very much! :)

[tudgeanator]

Does any one know how i could work out the 'impedence' of the moter so i would know how to place it instead of a speaker?

[jj32x]

hi
I would hazard a guess that the reason the motor works better with the extra diode is because of back emf (a.k.a counter emf, cemf and counter electromotive force). also if you used a stepper motor and the right circuitry then it would change speed depending on the frequency. that would be better in a way because on car/bike games the faster you go the higher frequency the revs get to (until you change gear).

cool its Kumba

[RidoKilos]

I laughed for about 3 minutes at this... "...come off and shoot into your face!" lol Really a cool idea by the way.

[sharkyenergy]

thank you very much.. :) let me know if you intend to build it.. :D

[superquack11]

where did you get the coaster game?

[sharkyenergy]

its "no limit coaster simulator". its a really good, cheap simulator

[Coffee bean]

that is cool

[Fizzxwizz]

How much larger of a scale can this be preformed on? For example, one of those fans that stand up and are plugged into an outlet in the wall.

[sharkyenergy]

hi! if you use a diode bridge and some huge powermosfet there is virtually no limit to the size.. :)

[Grey_Wolfe]

The best thing about this is that it is something that absolutely no one needs, yet we all would love to have one. lol Excellent idea, btw. You should think about prettying it up and getting a patent. Companies like MadCatz would sell something like this. Just a thought.

[sharkyenergy]

hi! thank you very much! well a system like this is sold by creative (?). they started to sell it 2 weeks after i posted this.. anyway too late.. :D i agree, something nobody needs and everybody wants.. :D

[Grey_Wolfe]

The fact that they actually started selling it only two weeks later does say they were doing it first. But still you could sell it, just make sure yours looks and works differently. Or just pretty the up and sell on eBay. lol. I saw yours first, so my vote goes to you.

[ultimatesx9]

Cool project, i like the way you think, by the way, if you dont have a old HI-FI, you could buy a 3.5 mm Audio jack from maplins (or radio shack) and attach the wires in there, then you could plug it into the Rear speaker jack on your pc. id acctully love to have this when im playing my GT pro seris on Wii, anyway, nice project and good luck with future ones

[ultimatesx9]

by the way, i forgot to say that i think that video used Roller Coaster Tycoon 3

[sharkyenergy]

hi! thank you for your replies! teh rear output of teh computer is not amplified.. the motor wont spinn.. but you can use the normal 20$ pc speakers and replace teh speaker with the motor... the game is not coaster tycoon.. the game is "no limits coaster simulator".. :) i plan a new video and tutorial today or tomorrow.. on how to play games in true 3d.. :) check out my other vid... the one with the chair.. bye igor

[drummonkey92]

this is awsum! i dont need it but want to make it anyway!!! also, realy great idea for the video (using a duster to show the power)

[sharkyenergy]

thank you.. :)

[blacjack1]

hey cool instructable man, definetely making this for my 360. I was just wondering if you could do a mod for a psp slim. no worries if u cant its just an idea i thought of. thanks

[sharkyenergy]

hi! there is no need of a modification for a psp. you can simply buy a "jack" adapter. with one male jack at one side, and two female jack connectors at the other side. you connect it to the psp instead of the headphones, and then connect the hifi to one of the two female jacks. :)

[soccerskyman]

DUDE! this is sweet! i want to make it and use it in roller coaster tycoon 3.

[PlanE]

Awesome, coolest idea, definably making this!..although there cud be more info bout the Hi-Fi connections, but no big;) But don't leave it to there, make a chair as well! (Y)

[sharkyenergy]

hi! thank you for your comment! every hifi is fine. the important thing is that it has line in to connect it to the computer. have fun and let me know about the results... :D

[madaanshivam]

all 3 diode numbers are P600M yes i am building it is it dangerous

[sharkyenergy]

yes all three diodes P600M.. it is not dangerous.. the only thing you have to watch for is that the motor spinns in the correct direction! remember to post any pictures.. :) i really reccomend you to build the vibrating chair.. it will increase dramatically the sense of beeing there with that one..

[madaanshivam]

what is the diode number

[sharkyenergy]

P600M are you building it?

[scotty3785]

Diode 'in the middle' prevents the motor from going in the wrong direction. Best guess would suggest that the other two diodes are used to drop the voltage across the motor, so if you put 12 across the whole assembly then approx 1.2-1.4v will be dropped across the diodes and the remainder will be across the motor

[chavez00001]

one in the middle is a flyback diode. prevents spikes going back to your circuit when motor is stopped.

[sharkyenergy]

thank you:)

[sharkyenergy]

thank you, so all the diodes make sense right? was afraid that due to my minimal electronic knowings i would write a senseless thing.. :D

[Cosmostrator]

Looks like you have made a half wave rectifier. If you add in one more diode you can rectify the whole wave, and get nearly twice the power. Check out http://www.kpsec.freeuk.com/components/diode.htm#bridge for how to wire it.
