Independent suspensions? Answered

I have been trying to figure out how to put an independent suspension on a Huge scale RC.  What I have noticed on large cars is that unlike small RC cars the rod going from the dif to the wheels is solid and can't extend/shrink.  Why doesn't this bind up? I have also noticed that for some reason they don't line the suspension up to move exactly up and down. The wheel's pitch is actually set up to change as the suspension depresses.

Declaration of Independence

When in the Course of human events it becomes necessary for one people to dissolve the creative bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.We hold these truths to be self-evident, that all makers are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Tools, Warranty and the pursuit of Customness. - That to secure these rights, Websites are instituted among Makers, deriving their just powers from the consent of the members, -That whenever any Form of Website becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Webspace, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Ideas and Projects. Prudence, indeed, will dictate that Websites long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Webmasters, and to provide new Guards for their future security. - Such has been the patient sufferance of these Users; and such is now the necessity which constrains them to alter their former Systems of Website. The history of the present CEO of Instructables is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these Members. To prove this, let Facts be submitted to a candid world.He has refused his Assent to Features, the most wholesome and necessary for the public good.He has forbidden his Staff to pass Forum Topics of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their Public Records, for the sole purpose of fatiguing them into compliance with his measures.He has dissolved Comments and Topics repeatedly, for opposing with (wo)manly firmness his invasions on the rights of the people.He has refused for a long time, after such dissolutions, to cause others to be elected, whereby the Legislative Powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.He has endeavoured to prevent the population of these Users; for that purpose obstructing the Laws for Naturalization of Free accounts; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Features.He has obstructed the Administration of Justice by refusing his Assent to TOS for establishing Moderating Powers.He has made Sherrifans dependent on his Will alone for the tenure of their offices, and the amount and payment of their salaries.He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people and eat out their substance.He has kept among us, in times of peace, Standing Filters without the Consent of our legislatures.He has affected to render the Military independent of and superior to the Civil Power.He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our TOS; giving his Assent to their Acts of pretended Legislation:For quartering large bodies of armed troops among us:For protecting them, by a mock Trial from punishment for any Murders which they should commit on the Inhabitants of these States:For cutting off our Allsteps with all parts of the world:For imposing Pro fees on us without our Consent:For depriving us in many cases, of the benefit of Refund of Fees:For transporting us beyond Seas to be tried for pretended offences:For abolishing the free System of Exchange of Ideas in a neighbouring Webspace, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these directories:For taking away our Favorites, abolishing our most valuable Features and altering fundamentally the Forms of our Websites:For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.He has abdicated Government here, by declaring us out of his Protection and waging War against us.He has plundered our seas, ravaged our coasts, burnt our towns, and destroyed the lives of our people.He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation, and tyranny, already begun with circumstances of Cruelty & Perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized website.He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Spammers whose known rule of warfare, is an undistinguished destruction of all OSs, platforms and softwares.In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince, whose character is thus marked by every act which may define a Tyrant, is unfit to be El Jefe of a free people.Nor have We been wanting in attentions to our Hacking brethren. We have warned them from time to time of attempts by their staff to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.We, therefore, the Representatives of the Members of Instructables, in Freenode on #instructables, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good Posters of these Forums, solemnly publish and declare, That these united Dirs are, and of Right ought to be Free and Independent Sites, that they are Absolved from all Allegiance to the Robot Crown, and that all TCP/IP connection between them and the Site of Instructables, is and ought to be totally dissolved; and that as Free and Independent Sites, they have full Power to assign Mods, post content, contract sponsors, establish Advertising, and to do all other Acts and Things which Independent Sites may of right do. - And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our Tools, our Kiteboards, and our sacred Honor.None of the above, is, of course, intended seriously. Dur. IT'S A JOKE, peoplez. Sheesh.

Jack Daniels Independence Contest

Hi, I am sorry if this question is repetitive, and I figure who ever is approving videos for The Jack Daniels Contest is overloaded today, but I am just worried that my video submission is somehow void for some reason. Matter uploading my submission on Friday, I received the email stating: "If after two business days or so your project has still not been accepted, then it did not meet all of the requirements for participation in the contest.  You will then need to make the appropriate changes to your project." So I will not receive an email stating if I have done anything wrong, which I have not, because the email also says: "Requirements: - Video of one minute or less explaining what you would do with $25,000 prize - Date of birth in the text part of the entry - Entrant is 21 years or older at time of entry" And I meet all of the requirements: Should I be worried?

JD Independence Project IP rights

Apologies if this has been asked before, but I've looked around and haven't been able to find anything dealing with the IP rights associated with the JD Independence Project contest winners.  Typically Instructables contests don't run into this issue as they are dealing with already-created content and as such the IP is either available already or made available by nature of the public release of information (rendering the content ineligible for patent, at least under US IP law).  With this particular contest, however, the prize is meant to preemptively fund a project, business, etc - so there's definitely the possibility of IP creation.  How would Instructables/JD deal with this and what assurances do entrants have that IP generated as a result of the contest remains their own?

Electronic help required - independently powering a CCFL

Hi, a friend of mine recently had a problem with a laptop where the screen went dim. I tried the obvious, screen settings (it didn't have a monitor swith-off button :S ) and reset the bios with no luck, so I thought that the problem was probably related to either the cable, the inverter or the backlight. I tried a new lcd screen with a known-working backlight and it failed to work. I also purchased a new cable and a new inverter but the backlight still failed to turn on. This now points me in the direction of a motherboard problem. I am going to take a multimeter and test the voltages going from the inverter and to the inverter. If these appear to be correct, is there any way that I can get the backlight to turn on? If the voltages are correct I would assume it's something to do with the light control and stuff, and wonder if I was to say, disconnect all the wires from the inverter but dc supply and ground (and I think there is a connection to the oscillator?), would it work? If there is no voltage going to the inverter, does anyone know how I could power the backlight independently? I would imagine it would take some sort of power regulator and maybe a separate inverter? Thanks

Transition between two Steppers with independently assigned cues

Hello. I am going to use two step motors, two easy-drivers, one arduino uno. Each step motors have gear to rotate, front and back. First, I'd like to assign multiple rotation cues for each steppers. such as, int step1cue1 = 329 int step1cue2 = 582 int step1cue3 = 1038 int step1 cue4 = 1790 ... int step2cue1 = 568 int step2cue2 = 1004 int step2cue3 = 1928 int step2cue4 = 3592 ... and each stepper needs minimum 0 and maximum value, such as, int step1maxcue = 8372 int step2maxcue = 8421 each rotation speed and acceleration need to be set and controllable as well. I would like to use rotation speed = 0 to make the stepper stopped at the cue. ** Operation Both steppers start from 0, First, stepper1 rotates to randomly chosen cue from its step1cues, when it almost reaches to the chosen cue, stepper2 starts to rotate to randomly chosen cue from step2cues.(stepper1 stopped at the cue with speed=0), when step2 almost reaches to its cue, stepper1 starts to rotate to another randomly chosen step1cue (not the current cue).. (stepper2 stops with speed=0).. and repeat this transition between two steppers. I would like to use the code from this, 'Example 4: Running multiple stepper motors'

Web Hosting Help for a Non-Profit

Hi,So this year I joined a non-profit organization called The Student Free Press Group. It distributes a newspaper called The Independent about once every 2 months or so. Here is a little blurb about them. The Independent is a student-run, student-owned, student newspaper and non-profit organization. It is important for us to emphasize "student" because we are in no way affiliated with the school district or Memorial High School.Philosophically, The Independent strives to be an open forum for students to express their views without oversight from school or governmental authorities. While news articles are required to be objective, editorial opinions are not censored; inclusion in the paper is based upon the quality of the writing rather than the nature of the opinion. The Independent serves the community not only by providing a forum for expression but also by giving students an opportunity to develop skills in writing, reporting, leadership, and independent initiative by becoming writers or editors of the paper.The Independent was born during the 1990-1991 school year after a censorship dispute between the administration and the student-edited school newspaper, The Sword and Shield. The administration, once a staunch supporter of student journalism, began to exercise the powers granted to it by recent Supreme Court decisions and sought to review each issue prior to printing. After encountering fierce opposition to publishing a news article revealing sub-par minority grade point averages at the school, all but one member of the editorial staff of the official school newspaper resigned in protest and, the following year, began publishing The Independent. Since that time, The Independent has gained the readership and the respect of students, faculty, and administrators.So here is my task. I need to create a professional looking website for the newspaper. I'm already have a domain but I am looking for a good, free hosting provider.So I am looking for a free web host that will give us a lot of space and a decent amount of bandwidth. In return I will allow them to put ads on the site and in the newspaper which is distributed to about 1,300 people. So I'm wondering if anyone would be interested in sponsoring the site/newspaper. If anyone knows anyone who would be interested please give a link or there email.Thanks for your time,Joe Rowley

I have the editing and lighting techniques down, but is there any way to adjust my video camera so that I can get DSLR-like quality? Like adjusting shutter or something? I know that the advantages of a DSLR are their large sensors and supreme ability to capture light using these sensors. Can I achieve this, at least a little, with my video camera? I can adjust the white balance, shutter, iris, and focus, on my camera. Any links and/or help is greatly appreciated!

I need to remote controll two 12 volt motors each one needs to operate independent of the other and both motors must go forward and back if you have any tips or diagrams on how to remote controll this please leave a comment.

Controlling two servos with one pin and a NOT-gate

Here's an interesting idea. It may be possible to control two servos independently with only one output pin and an inverter/NOT-gate. Normally, a servo is at its 'center' position when a pulse is 1.5 ms & its angle (or speed for continuous servos) is based on the difference between the length of time of the pulse it received & the base-time of 1.5ms. The servo itself does not react to the time BETWEEN pulses however. If the signal was inverted, the result would be a pulse with a time being that of the time between pulses of the initial signal. If the width of a pulse and the time between pulses can be independently controlled, then it would be possible to control one servo with the signal directly, and another servo using the inverted signal. I found something similar here [] but it seems to be intended for 'reversing' the signal used to control one of the servos.

20$ for Arduino sketch

I will pay 20$ for Arduino sketch. please if you can do; reply here and I will send the flowchart. Flowchart steps: Arduino has one PIR sensor input. when sensor detects a surface at distance 25 cm or closer; it triggers 2 DC motors and 3 servo motors to move randomly. the 3 servos move back or forth at range 0- 60 degrees. Direction is random and amount of movement is also random. but speed is fixed 20 degrees per second. the 3 servos should move same time but independently. the 2 DC motors move forward only for 250ms at full speed. but the interval between on move and another is random between 1-3 seconds. they both independent from each other. you are free to choose which pins you use for input/output. use arduino Nano. Thanks for reading
