Which Phonograph/Gramophone models created the BEST sound fidelity & quality?

Hi, I am designing & building my own record cutter, and phonograph player. I am trying to track down which Phonograph/Gramophone models were known to have produced the greatest playback sound quality & fidelity? Specifically, which diaphragm design & material, and what kind of reproducer (sound box) design provided for the greatest playback fidelity. Are there any knowledge around which model(s) were known for this? To elaborate a bit, I'm designing and building my own phonograph recorder & player, but using modern materials. No electrics (still driven by a spring motor, and no electronic sound amplification), but I'm happy to use modern materials. As such, I'm going for the greatest playback fidelity possible, and I figured I'd start by looking at the best designed reproducer (sound box). If anyone has a better material and/or reproducer (sound box) design, please share? Thank you so much! Mark seegem@me.com

What to do About Shadowman39's "Official Guide to Knex Ball Machine Lifts"

     As you know Shadowman39 on December 17, 2009 posted his Official Guide to Knex Ball Machine Lifts, but as of July 2011 he has not updated his guide. In fact his last comment on instructables was September 28, 2011. And since then there has been over 15 new lifts. So I was wondering whether someone should post a new and updated guide with all the new lifts created since. Not with all the lifts on Shadowman39's guide, but all the ones created since. It could be called something like, "The Official Guide to Knex Ball Machine Lifts 2" or something like that. If none of you guys are up to the challenge I will gladly take on the responsibility, but first I want to here what you guys think.                      UPDATE Sorry guys. Sorunome says he has been communicating with RNB and Shadowman39 via skype. He says that RNB will continue Shadowman39's guide as soon as possible. So please don't post another guide. Thank you.                                                                                                                                                                            KneXtreme

K'NEX Tractor Pulling

Figured I'd throw this out there- There is a small group of us in southwestern Ohio that have started a  local pulling league for K'NEX tractors. It's great fun and probably more entertaining than it should be. Is there anyone else out there doing something similar? We're always looking for ideas to make it better. We're also always looking for new competitors if you're local and interested. There are classes for every level from a two wheel drive 'box stock' type setup all the way up to AC and cordless drill motors on tractors that only have to be 50% K'NEX. Thoughts? Interest? Offers of sponsorship? ;)

Have you ever broke up with somebody that was special to you? Have you ever since that awkward moment when you guys are in the same place? well I have for one. Its always so awkward when s/he says let be friends when you know that you guys arent going to be acting like freinds. Then not only does it effect you but it effets your friends if you guyss have the same kind of friends!!! I hate this so much. You know you guys cant be friends, you still have feelings for s/he, and ya have alot of classes together! So what should you do?? Should you guys be enemies? Should you just erase s/he from you life permentally? I for one dont know what to do.... Maybe you guys know? Please answer this question as if it was you!!!

Are there any knex block pins on this site?

Are there any block pin guns on this site? because i made one and wanna know if it is unique. i have seen one on knex innovation but it didnt work very well. so i wanted to make one that worked very well with a good removable mag system. the reason why im asking is because i wanna know if im the first one. i dont weanna brag about it either because that gets annoying now a days. please respond and if you have one share your idea or creation here!! PS: people please stop posting the same type of guns over and over again. we have enough of them. if you really care about knex guns then you would start looking into creating different types of guns and mechanisms. if you do post the same kind of gun make sure it has everything on it. for example: an sniper rifle should shoot more than 150 ft and have a removeable magazine and look nice not crappy. should be strong and not weak. anyways you get my point.

I need some help with paper mache angry birds for a party game

For my daughter's b-day I want to make an Angry Bird game out of small pinatas. I've never actually played the game myself (prob the only person in the world who hasn't) because I don't hove time. But I thought it would be fun if I could make small birds and pigs out of paper maché, about 7 inches in diameter. Then I want to make a catapult, and hang the birds from strings from the ceiling, and have the kids shoot the pigs at them. How's that sound? First of all, is that how the game is played--pigs hit birds? Or is it vice versa? And I need the pig pinatas to be durable enough to shoot without collapsping in the catapult, and hard enough to break the birds. I want to put candy in all of them, and have quite a few on hand so all the kids can get a shot. I made a cool catepillar pinata a couple years ago for her but the kids couldn't break it because I made it too thick -__- So, I need some help with my "recipe"... Thanks

They've even been so kind as to provide full instructions, parts lists and code, just so anybody who wants to can make their own! Kudos, chaps.

Hispanic or Latino?

I cringe everytime someone uses the word Latino when generically speaking of Spanish-speaking people. I prefer to be called Spanish or Hispanic. Some people may disagree with me but I think that calling me a Hispanic describes my true ethnical and cultural origin. Although many people will bring the fact that the colonization of America by the Spanish conquerors was bloody and opressive, we still owe to Spain the origin of our countries. From Mexico to Patagonia and the Large Antilles, the Spanish conquistadores left their footprint in the form of language, architecture, religion, cooking, stories, art, crafts and culture. In contrast, a Latino is anyone who descends from people that speak a Romance language like: French, Italian, Portuguese, Spanish and Romanian. By that definition, when we speak of Latin America we include countries like Brasil, Haiti, French Guyana and, Surinam. The same definition could apply to Italian-Americans, French-Americans, French-Canadians, and Cajun people.

New Mag Idea

So, I was thinking and I came up with a new idea for a mag.It works almost the same to the P90's mag system. So in a p90 the rifle rounds sit sideways in the mag. Then, they get rotated into the barrel and shot out. Since the bullets are sideways in the mag it can hold alot. So I was thinking if we could use that idea with a bunch of green rods sitting sideways. The olny problem is that the bullets would be fired out of the gun sideways which would decrease the range of the gun. Heres a simple pic to show you what I mean _______________mag_________________ 0000000000000 bullets 0000000000000000\ 00000000000000000000000000000000000 \--------------barrel----------- ----------------------------------------------------------------------------------------- Yeah. I know its confusing but all the little 'o's are the sideways green rods then they get pushed into the barrel and fired. The really only point of all this is to increase the mag capacity of all horizontal mag. So send me a message if you have any questions.

Why you can never have a "true" knex semi auto with decent power/range.

Ok here goes I will try to simplify my theory down a bit so everyone can understand: basicly energy cannot be created or destroyed, it can only be converted, eg kinetic into heat, chemical into kinetic ect. Knex guns are no exception, the enery has to come from somewhere, in most guns this takes the form of pulling back a pin or rubberbands to create potential energy, this is released when the trigger is pulled, this potential energy is converted into kinetc energy and this is how the bullet is fired. A semi automatic gun is required to fire every time the trigger is pulled, but the energy still has to come from somewhere. RBG's take this into account as each band is pulled back and has potential energy stored, however many knexer's opinions differ on whether this is truly semi automatic, many calling this type of gun a psuedo semi auto. Other guns use the energy imparted on pulling the trigger to create the potential energy to power the bullet, this is considered to be a true semi auto, however the main drawback of this system is that the amount of energy that can be transfered from the trigger to the bullet is very limited, therefore this type of mechinism has limited power. So if the problem is energy how do we solve this? one possible answer is to have an extra source of energy, such as a motor or a winding system that puts extra energy back into the system, however this approach will not give you a "true" semi auto as you will have to have an external source of energy, that and the fact that knex motors do not have the power and torque needed for this system. So what's your opinion, do you have anything to add?

I am still curious....and wanting to know the best methods of acquisition of said kits...

I am curious, not so much for my own self (after all, I am nearing my mid fifties) but because a youngster that I am mentoring likes this kind of thing, is there any way to get a decent "collection" of parts together without spending half a fortune? She prefers robotics, dinosaurs, and human anatomy to other subjects, but loves to build just about anything.  And since erector sets and lego mindstorms sets (she's a bit advanced for an 8 year old) are so expensive, and she does have a small K'nex set started, I figured we could "build" on that one, if it can be done at a reasonable price.   Sadly for me, "reasonable" is much less than the average idea of reasonable. When I was younger, I got an erector set that could build literally hundreds of different "contraptions" for about $20-$30 and now I see on line a "discounted" "contraptions" set that can be used to build 6 different things for about the same price.....not really comparable in any way.  Tinkertoys are not really that "useful" for "creating" things as far as I could see (had those as a child also and the one I am helping doesn't care for them either). She also has a set of lincoln logs, but bores of them quickly as her imagination has not yet had a chance to "kick in" :-) I know I asked a similar question recently (in the general forums) that was a bit more broader in perspective, so I thought I would narrow it down and get some input from you all. Thank you in advance !

Expanding Thought Process, the Mind, and General Creativity

I believe that, for the utmost of simplicity, I should begin this topic with the fact that I am a teenager who is quiet passionate about electronics, engineering, and teaching others in general. I have run several websites (each generating a plus of 200 unique visitors/day), created many circuits for school applications (projects), and many similar forms of expressing oneself such as writing. Being just about 15 today, my mind is far from creative, though. Less then three years ago, I was at, what is at this point, my "creative prime". I was publishing quality articles daily for my website, and greatly grew in the ranks of superiority among other websites in my niche. At ages 12 and 13, I was pushing content out - in addition to designing many webpages through core-coding languages - on a daily basis, requiring a load on my creativity to be pulled. Nonetheless, I always managed to tap into my inner-creativity and pull out great ideas. The Point of This Thread Less then two years later, though, I'm stuck in a bit of a muddy puddle. I cannot tune into my own creativity, for the well that it is is now very much dried up. I'm looking to somehow expand my mind and thought process. Are there any activities (keep it legal, guys(;   ) that can help? It'd be a huge inspiration. I can come up with the ideas for circuits and execute them, but from there, all of my creations fall short - they don't end up how I pictured them. The visual aspect of my brain is, uh, malfunctioning. Thanks(:

Of course, it's hard to follow the "be nice" policy with something like this. Really, though, if the instructable was that bad, the instructor usually didn't actually care to do it well. If they did try, and it just turned out bad, then they can still be added. Including a few tips on their page to encourage improvement wouldn't be a bad thing to do. Mostly, though, this is for those really terrible instructables that really should be deleted. Something like "Make light from matches. Instructions: Go to a dark room and light some matches."

Notes on specific Laws - the Zeroth Law

This is where the whole Law thing started:There is a fairly regular kind of thread that appears here.It starts should I make an Instructable about insert topic here?You know what? The answer is yes. Even if nobody else on the site is even vaguely interested in insert topic here, it is probable that somebody with access to the internet, somewhere in the world, will eventually develop an interest in insert topic here and resort to Google. Since this site is googlable (is that a word?), they can end up here, grateful to you and potentially a new and useful member of the site.So, unless it breaks the guidelines for what is suitable here (basically, Please remember that this is a family site), and you're not just re-inventing the wheel, then the answer to should I? is always yes.This has become the Zeroth Law:If an Instructable exactly like yours has not already been posted, then you shall post your Instructable.Instructables are, after all, the whole point of this site. If nobody posted new Instructables, the site would shrivel and die.It doesn't matter what you make, as long as it falls within the bounds of "good taste" (define them how you will). What does matter is that you make. If you look at other sites limited to making only one kind of thing (jet engines, chests of drawers, whatever), they tend to have a slow input of new projects, with many variations on a few basic themes posted early in the site's history. Instructables has a daily project count that rarely drops below ten, and sometimes hits thirty.Addendum to the Zeroth LawIf your Instructable has an identical goal to a pre-existing Instructable, but achieves that goal by a different or improved route, or in a different style, then you shall also post your Instructable.Why the addendum? Sometimes potential posters worry - there's already a project quite like mine, so should I waste bandwidth with mine? Of course you should! Some people will prefer the first version, but other people will prefer your version - maybe it's easier to read, the photos are better, or they prefer your sense of humour. Maybe you use different raw materials, or use different tools. Either way, unless your Instructable is indistinguishable from an earlier project, you should post your own.
