Help modify the maximum rotation for my steering wheel.

Hi everyone, i have a steering wheel from trust , i dont know the details. so, i attached a photo to understand better what i`m talking about. i play racing games, and i need a maximum rotation, i installed the drivers for it, so when i am in aprox 45 degree rotation it show and he behave like i`m in the maximum rotation. The maximum rotation is aprox 135 degree, so its a difference between them. i opened him, because i finished an tehnical university with a electromechanical profile, and try to modify the potentiometer that handle the rotation. i tried to put a smaller one, a bigger one, even try the fine course like its called, but nothing, i attached a photo of it two, maybe i forgot something. If anyone think or have an idea what to try , please help, because i have no other idea.

Steering wheel desk

From the MAKE blog, comes a pass-through of a product available on Amazon. The steering-wheel latch-on table itself is fairly pedestrian (pun intended), but the legalese is just delightful. Read it for yourself at http://blog.makezine.com/archive/2009/09/re-make_simple_elegant_handy_steeri.html .And before you comment, please keep in mind those orbital lasers. I have access to the launch codes, and have no qualms about using them.

Knex 4wd w/ steering

I'm building my own 4wd truck with knex, and I want it to have steering. I found my own weird and not-always-reliable way, but I want to see if there is an easier way to build it, like using joints and axles. I can find 4wd cars and cars with steering, but none with both. Suggestions must be MOTORIZED, and WITHOUT MODIFYING PIECES. Thanks for the help!

What frequency to use for a gaming steer?

I have an old gaming steer which is not compatible with win 7+, and I can’t find its drivers either. So, im manipulating it on my own, and will use 4 IC NE555 and a potentiometer in astable mode to press [w/s/a/d] with I-don’t-know-what range of frequency. Is there anyone could suggest me use what range of frequency? I thought 700–4000 Hz would be ok. But I have no idea if it is, or not

Riding in style for a 14 year old that is...

I have a challenge/ project/ idea for you all! Have you ever sat in a shopping car while somone pusshes you around? Me and my buddies did this a few days ago and i thought to myself what if this shopping cart had a motor. A shopping cart made for driving that you could sit in and steer! This inspired me to make a moving vehicle. Ideas that came to mind were narrowed down to either the shopping cart with motors and steering wheel or the mini-tank which would be a sheet of 1 inch plywood on wheelswith a steering system aswell. Has anyone ever done something like this before?

PC USB steering wheel 180 degrees 1080?

I've got a GEMBIRD STR-SHOCKFORCE-M Multi Interface steering wheel which I bought new about a month ago. It is pretty much "you get what you pay for" as far as it goes, and its not nearly as good (nor did I expect it to be) as, lets say a G27. Now, I have never used a G27 but I saw some videos, and it seems that it can do a full turn, while this one only does 90 degrees to each side - 180 in total. I'd like to modify it somehow so it can be rotated 1080 degrees like in a real car, or atleast somewhat more than 180. I found it useful in some racing games where turning needed to be quick and sharp, but in some simulation games it just jerked the ingame steering wheel like it were out of cardboard and ultimately I end up parked inside a wall or on top of a tree.(adjusting the steering wheel AND ingame sensitivity setting to lowest didn't help) If anyone needs pictures I'll post them later today.

DIY Steering Wheel

Hello, I'm new here. So, lately, I've been thinking about making a steering wheel for my PC, with a simple up-and-down gear box and 2 pedals for acceleration and brake. Steering Wheel. I'm using a polystyrene sheet, to cut out a wheel from it, and in the center, there's space for installing a phone holder. I'm planning to use my phone's gyroscope and simulate it to the PC. Pedals. I've figured by using foams underneath, we can place a nail and a foil separated and when we press the pedal, the foil touches the nail and circuit gets completed. I've a general idea, but I'm stuck on how to give that signal to PC as to simulate as a button (say for acceleration and brakes.) Gearbox. For the gearbox, I figured it might be easier to make an up-down box (as in pulling the level shifts the gear up and vice-versa.) Here too, The part where I'm stuck is giving the signal to the PC. Anyone who can help me, please?

sidecar wheel position

I've looked up sidecars on google and found lots of information for sidecars on vehicles that have front steering only in which case the sidecar wheel tends to be positioned parallel to somewhere between the midpoint and the rear of the vehicle, however if the vehicle has both front and rear steering would the sidecar wheel be best positioned parallel to the exact midpoint or not?

Help needed on FLL robot

Hi guys, this year is my third year that I am going to be participating in the First Lego Leauge. (btw, we are using the ev3 sets) This year, my team (of 3) decided to build a car based robot. I have designed the steering mechanism and it works, and I have made a basic chassis that links everything together, and I am using 2 big servos for power(rear wheel drive), they will drive in sync, and a medium servo to control the steering, and since I had to mount the medium motor in the back, I used a driveshaft to control the steering at the front. My problems are 1)  whenever I program the medium servo to turn right, it suddenly goes out of control and goes full power to the right forever, and skips gears in the process, breaking the motor. I have tried using it outside the robot, and it works fine. 2) I am not sure if my design is a good idea, and if I should stick with tank drive. This years map need speed and precision, and the car steering lends itself to both of those, but, its unreliable, and the tank drive is not quick and not precise, but reliable. So, I need your guyses opinions, do you think I should stick with the car steering system or not? And why?

Wooden Go Kart?

*Hopefully this is the correct category..... Hello all! I am quite interested to start learning woodworking (already have some knowledge) And what better way to start that with a gas (or electric) go-kart :-P? I know fair amount of people who have built things out of wood, some younger than I am (14). And it seems like a very good skill to have. Plus, if I am good enough at it and I outgrow the go kart, Ca-CHING! I could sell it for profit (If it is in good enough condition still). I'm currently in 8th grade but I cannot take a woodworking class until 10th grade, So why not start? I was also wondering if the Ibles community could help? I could use some ideas, and I will need alot of info for the engine and frame.(If you can even find PEDAL CART info that would be awesome too). My plan is to have it done by mid summer (July 10 for me). This may seem like too much for me, but I want to build one that, if it doesn't have an engine, one could easily add one (I realize I can not run a gas/lawnmower engine on its side) Please leave your thoughts below!!

DIY AUX unit with steering wheel controls

On my previous car, I hacked together an aux input with two CD-ROM plugs as described in many places on the Internet (here's one). I was really happy with it, and fully intend to do the same on my new (?) second-hand car, which also has CD-changer support, but no AUX. (Neither car had a CD changer installed, because I couldn't be bothered). The new car has steering wheel controls though, and I thought this could be a nice upgrade, but I'm really not sure how to do it. The pin-out diagrams for the CD changer plug (which I stole from here) for the CN702 12 pin connector shows lines 9 and 10 as TX signal lines. Since there are track (and disc) up and down buttons on the radio, I assume this is how the commands get through to the CD changer. And the phone obviously has support for headsets with track skip buttons. So the stars seem to align. Except for the details.  First, a normal audio cable only has three wires and one with headset controls have four: Ground, left, right and comms. I think I can connect the following pins on the 12 pin connector to ground: 6, 7 and 9 and then 1, 2 and 10 get connected to the correct wires. Is this correct? Second, I have no idea if the actual signals sent to TX for a CD changer bear any resemblance to what the phone expects from a headset. Does anyone know? I can probably hack a test using a bread board. I think. Third: I really only dabble in these things. Did I miss anything really important?

toy rc car steering mod

I just got a sorta good used R/C toy car for $2, pretty nice for $2, and it works too full suspension, differential drive, two speed gearbox, and the steering mechanism uses a servo but this servo has all of it's control electronics out side the gearbox and on the single PCB the car uses. I just want to hack it so that I can turn it into a 2.4ghz (freebie RF modules from cypress yay) controlled "hobby grade" car with variable speed and such this gearbox has 7 wires sticking out of it, 2 are to power the motor itself, another 2 is 6v+ and ground ( - ), the last three is a potentiometer in the mega ohms range, higher than 20 mega ohms for sure, because it goes out of my multimeter's range if it's at neutral, but goes to about 10 mega ohms when the wheels are turned now, my datasheet for my PICmicro says in the A/D converter section "The maximum recommended impedance for analog sources is 2.5 kΩ" I can't really replace the potentiometer inside the gearbox, there is room for me to fit in my own, what would you do? *add parallel resistors to the potentiometer (probably easiest) *I can have a piece of paper shaded from light to dark and have a photo resistor tell me the darkness of the paper (might get jerky) *I can probably directly attach a potentiometer outside the gearbox directly in line with the output shaft (durability issues) *or I can put a gear on the shaft and have a potentiometer above the gearbox (I would need to cut my chassis to fit it) what sounds good?

The $2500 Car

From a NYTimes article, a story about a new $2500 car hitting the market in India. It won't pass US or European emissions or safety standards, but still- how neat is this?For Tata Motors of India, which will introduce its ultra-cheap car on Thursday, the question was, what could it take out?The company has kept its new vehicle under wraps, but interviews with suppliers and others involved in its construction reveal some of its cost-cutting engineering secrets — including a hollowed out steering-wheel shaft, a trunk with space for a briefcase and a rear-mounted engine not much more powerful than a high-end riding mower.The upside is a car expected to retail for as little as the equivalent of $2,500, or about the price of the optional DVD player on the Lexus LX 470 sport utility vehicle.The model appearing on Thursday has no radio, no power steering, no power windows, no air-conditioning and one windshield wiper instead of two, according to suppliers and Tata’s own statements. Bucking prevailing habits, the car lacks a tachometer and uses an analog rather than digital speedometer,

Excercise car?

What I am designing (and planning on working on very soon) is a vehicle with the possible speed of a gokart, but with a propulsion system similar to a bike. The mechanism itself would be a simple push pedal (like a car) but with a gear system like a bicycle. Upon pushing down the pedal, a shaft connected too it would then push against the foremost gear. and that gear would push another and so on until it comes in contact with the rear wheel, propelling it forward. A simple spring between the pedal and floor will allow the pedal to return to the original position. However I cannot seem to get the steering and brake system down right. Should the steering be that of a car and use 2 wheels on the front with a long axel connecting the 2? or more like a bike, with a one wheel turning system. (aka. should it be a 4 wheel or 3 wheel? Might depend on weight distribution and balance, though both could be possible.) and how should the brakes be arranged? a pedal, like a normal car brake, or a stick beside the driver, like an emergency break, as well as where the brake pad would come into contact with the rear. On the axel or on the wheels? Last (and most definitely not the least) is that while this vehicle must be sturdy, it must also be light weight. So any and all material recommendations for parts would be greatly appreciated. (cheap would also be appreciated) (My thought for material) chasis - light, but firm (strong) wood. axels - aluminum or steel tires - Gokart/ riding lawn mower turning wheel/steering - wood or plastic seat - whatever I can find that's soft (not a major thing) safty belt - I may not be able to test out the prototype (kinda thick) so I need the crash test dum *ahem* "driver" to survive incase a crash were to happen. brake pad - rubber so that it causes the right amount of friction but not enough to damage any parts.

Things your instructor never told you...

I was chatting about changing driving tests with a colleague today, and I realised that I had been driving longer than she has been alive, in often rougher conditions.That means I knew a couple of things about driving that she didn't. Others here are in a similar state as I am, but many are in a similar state to her - young, and only learning (or yearning to learn) to drive.How about sharing tricks that make your driving easier and/or safer that your driving instructor never taught you?Here're my starters:Reverse is lower gear than first - if you're stuck in a pothole, or trying to get up a hill your car can't quite manage, try again backwards.Watch your thumbs - when driving in water, snow or mud, or otherwise uneven ground, keep your thumbs on the steering wheel, not in the "hole" - sudden unevenness can kick the wheel and spin it with enough force to break thumbs, especially if you don't have power steering.Brake as you enter a sharp turn, accelerate as you leave it.In urban driving, skill beats power every time (me and my 900cc mini could beat my mate and his three-litre Capri Sport across town every time).On icy wet roads, slow down gradually with the gears instead of with the brakes

Another interesting story from Africa about handmade goods. I'd love to get one of these.Phillip Isohe is a metal fabricator in the jua kali, non-traditional industrial sector, in Kenya.

What's most interesting is the excruciating attention to detail that he puts into each one. In fact, they each have motors with working lights, steering, engine and interiors. full story

Kite-Biking? Street Luge Meets Kite Boarding Meets Tricycles

(WARNING: If I or anyone else should try this or try to recreate the idea in any way, please be safe, wear full body racing gear Like for motorcycles and such. If I do this I will definitely try to be as safe as possible.)Okay so I was fooling around on the net and ran into Turbo Pro Tricycles. http://www.primepedalkarts.com/resources/2007picturboyellowbig.jpghttp://www.primepedalkarts.com/turboproyellow.html They have a Demo Video that's about 20mb if you'd like to see some action with it. Anyway, as soon as I SAW the Trikes, I was thinking EXTREME. Basically the bikes steer like Luge boards, except you pedal them to make them go, not gravity. Well The bikes have a 'Free' gear which is used for coasting, and I was thinking with some modding, This could be an ATV or street beast (Permitted that these would be allowed in your area). Just add a Kite and steering system with the mandatory trike mods to follow (A list at the bottom) and you'd have a new (I hope) extreme sport 'KiteTriking'. I'd keep the pedals functional if possible so that when not skirting around on Kite-power you can pedal around. Although a completely other idea might be to try to motorize it electrically. (someone come up with a concept?)The mod list would most likely have to include:Some appropriately sized metal alloy wheels with racing or All-terrain tires to match.A reinforced chain or complete replacement.Brake replacements or modding to make them more efficient.Adding an Emergency Break.Reinforcing the frame.Changing the seat to a more sturdy, ergonomic one.And changing the pedals to aluminum ones.Kite mounting and emergency release mechanism.Some sort of rear storage space.

Potential $5 RC Hovercraft

Hey y'all, I was bored, so I made this RC hovercraft, kinda like a Tiny Whoov, from the guts of a $5 RC helicopter (sold at most FiveBelows). The idea is that a hovercraft is more fun than a cruddy helicopter, in addition to being a fun and easy DIY project for the weekend. It could be a nice gift to a kid. My first concern was that the motors would not provide enough power to get the thing moving. They give more than enough power, and this thing can MOVE. My second concern is that the differential thrust steering system (one motor turns faster than the other, steering the hovercraft) would not be effective enough. This is still a problem that I don't have the enthusiasm or time to solve anymore. Maybe someone could figure out how to reprogram the FC board to have more differential thrust (is that possible?), or somehow configure a servo or actuator without raising the cost of materials too much. Anyway, here's the concept, go have fun with it.Supplies:Foam platesHot glue$5 RC helicopter with 2 motors and receiver (LED optional, but really cool)Connector (the battery might be soldered directly to the FC board, so this will make it easier to fiddle with)Soldering iron (not %100 necessary, but it can come in handy)Propellers (see design notes)Design notes:Notice how the underside of the hull is curved and smooth. I used propellers from a Blade Inductrix FPV Pro, but any micro quad propellers should work. Notice the nice little compartment under the FC board where you can stick a battery without the need for Velcro or glue. This would be a very easy FPV mod, but that would add about $20 to the cost.

Recumbent cycle: "blue sky" design query

I am not one of nature's cyclists. I didn't actually learn properly until I was in my twenties. My bike is very old, very rusty and very, very heavy.However, I feel that I "ought" to cycle more, for shopping trips and the like. I quite like the idea of switching to a recumbent, but they are expensive (current available funds: zero).So, I'm playing with the idea of rebuilding my mountain bike into a recumbent (and learning how to weld on the fly?).In the sketch below;The black section is the back of the old bike, turned upside down.The blue section is the front of the donor bike.The red part would need fabricating somehow.I haven't thought properly about steering mechanisms, but probably under the seat, via cables to arms welded to the forks of the will-be-the-back wheel.Would the bike, as I have sketched it, in principle, work?I'm bothered about stability, especially at take-off and landing. Am I worrying unnecessarily? I have access to a second donor cycle. Is there any mileage thinking about "doubling up" the blue section, to make a trike? Not massively wide, but I could add luggage space, or an extra rear-facing chair-style seat.Brakes: before I cut up the bikes, am I right in thinking that I just remove the cables and levers from the handle-bars and add them to the under-seat steering?Gears: the donor bike is a mountain bike, but I never used all the gears anyway. This area is pretty flat - can I get away without any gears?Coasting: although the back of the donor bike ends up upside-down, it is still turning the same way, so I can still coast OK.I'm sure I've missed something obvious...Anyway, even though I've not decided to do this for certain, I'd appreciate any comments or thoughts.

I have limited use of my arms which should allow me to control the steering but I am trying to get another degree of freedom to control acceleration and/or braking One of the ideas is to use a piezoelectric type force transducer in the mouth to control and acceleration via an arduino or similar. The transducer would detect bite force and it would be converted into control signals for the throttle and/or brake. It would be embedded in a gumshield and it would be acceptable to have a cable coming from the front of it to the control System. I am wondering has anyone worked on such a project and could anyone point me in the right direction please. The gumshield may end up looking something like the image here.
