Reno we need Room to build an ART CAR

[JRoyale]

The word "significant" is arbitrary and unenforceable unless clearly defined. And I bet that YOU are NOT the guy defining the terms set forth in the agreement. As such, I am not surprised at your futile attempt to find a backbone for your inherently weak argument. You would be better served by shortening your handle to "tool" instead of toolmaker. "Tool" more accurately describes your abilities.

I very much enjoyed your attempts to find fault with my reasoning in this thread. I'm flattered that you took so much time and effort to attempt to form a coherent thought on my behalf! If this forum had online cookies or stickers, I would give you one!

So, you really don't get Burning Man, I see. It's a private event, so it can be as arbitrary as it wants to be. If you don't like that fact, don't come. That said, we typically bend over backwards to avoid being so, however, assholes and friends of assholes don't get nearly as much slack as nice people having a bad day.

As for enforcement, once you've exhausted the patience of the Rangers, things happen very quickly. Honestly, you should avoid that.

Regardless, I'm not really interested in having a conversation with you. You're an asshole, and I have enough those in my life already and don't need anymore thank you very much, and your not a Mutant Vehicle owner, so I could really careless what you bring to the playa. In fact, I really do think Burning Man would be better off without you.

I am, however, interested in why White Rabbit allegedly permitted his MV to altered after his inspection last year. He does claim to know the rules, so it will be interesting to hear his side of the story. Given your loose cannon nature, it would probably be best to take this off line, so I do suggest he contact us at dmv@burningman.com instead of remaining here in an open forum where you continue to insist on sticking both feet in your mouth.

You fucking retards know who i am talking about.

Dave ?

I keep telling you Dave's not here...

Well I'm enjoying the show and eating Popcorn, Gulping Pepsi, sharpening my tools, ect......







Relax dumbdog, I'm a landscaper and I sharpen my tools all the time..

[Box Burner]

hey toolmaker! better keep duffdog riled. He might actually gift you with that train horn. I know someone who has a trailer and could store it nearby. I bet there is a lot of col ways we could turn it into an art project for next year.

That would be an awesome gift. I've never had a train horn. I don't think he realizes how much I would enjoy his threats if he acted on them. 6AM is a little late for me to get up though.. I would rather he come wake me sooner so I can be ready for sunrise. We could dance together with 70,000 watts and free breakfast. I'm just social engineering him to deliver my breakfast and wakeup call. I'm too lazy to bring an alarm clock this year.

[oneeyeddick]

Dammit Box, don't blow our cover like that.

I get dibs on whatever air source he is gonna use to make the airhorn work.

Daddy needs a new compressor, or better yet, another co2 tank.

But I need it more... AND I am doing all the work here I might add.

[oneeyeddick]

OK , lets just settle this and attach it to Fishy's rig instead.

[HeironymousJosch]

This guy's a jagov.

I would like to know what a Jagov is...and where you will be camping. That way us "jagov's" can drive by your camp with our 70,000 watt sound system at 6AM and let you know just how wonderful we think you are!

How about 70,000 watts of uncheck the "Disable BBCode in this post" instead.

Just remember that the lack of rules that allow you to do that kind of shit also allow for tohers to get even. Don't get too upset if someone you piss off follows you back to your camp and returns the love. Since you can only drive walking speed its not to hard to follow you. OR Are you planning on speeding in our city while you act like an ass driving around camps with 70,000 watts. Aren't things that loud to be limited to certain areas.. say 2 and 10 oclock and deep playa? Maybe someone at DMV should reconsider your permit privilege?

And you fuckstiks wonder why nobody would offer you land. Think before you post when you come back with a new screename in a year or so. If you come to the playa with that attitude rest assured there are equally nasty folks to make sure you don't return. You will only get what you bring in return. Just try coming by where I camp at that hour with 70,000 watts.

I didn't know that your groups of friends personally owned BRC. And don't worry, we will wait until we are right outside of your window to turn it on, that way all your neighbors can be laughing their heads off when you piss all over yourself in the morning when your RV just about vibrates apart. Who knows, we may even offer to cook everyone else around you breakfast just to make sure that we are more popular than you are.

I will get what I bring in return? AWESOME!! I typically bring lots of attractive girls with me and lots of speakers and amplifiers. Does this mean I will get even MORE?!?!-- I'm starting to like your philosophy! Do you have any other tips for me?

Okay, the gigs up. This has to be a joke. This drivel has to be put on. Has this been revealed as a sweet prank yet? I haven't followed this thread in a couple of weeks. No way this level of asshattery is for real.

Actually HJ, I think this is just a clash between two schools of thought out on the playa. One being that BM is the best party EVER (with topless young chicks) and I can do whatever the fuck I want. The other being BM as a community with art, music, fire, topless young chicks and I can do whatever the fuck I want (as long as I'm respectful to others). It's different things to different people and some people get more out of it than others. I'm not trying to make peace here though. I'm enjoying my view of the train wreck.

I get dibs on whatever air source he is gonna use to make the airhorn work.

Daddy needs a new compressor, or better yet, another co2 tank.

My minitruckin' buddies have been putting train horns on their trucks for a while now. If its not plummed into the air suspension, you can use a Viair 380c compressor, with a 5 gal tank. PM me for a great train/air horn site. don't want to advertise it here, as to stay within the TOS. I say screw a train horn, I'm trying to track down a cruise ship horn!! (not for playa use though, of course)

Sorry but blowing a horn at someone is kinda…. I don’t know…Silly.

Seems to me this MV has become a BIG slow moving target.
Just remove the moving part…. just saying.

It really sucks when your u-bolts come up missing off the driveline while you were parked in deep playa showing off your sound system.
I know some one that removed a motor out of a VW while the guy was in the gas station. Hot Rodders they know too much about what makes your vehicle move… what are you going to do.
I’m not suggesting anything but this is Black Rock City piss off the wrong person and he will set fire to the man (or your MV) on Tuesday.

Just saying…

So a few questions if anyone can answer them..

If there is an increase in horsepower via engine boring etc will this increase the 138db 30,000 watts significantly? I wonder what could be achieved with a 500HP engine. Those 50s engines while awesome as hell aren't quite as powerful as what we have to play with now. How would one change the pitch/tone? What would happen if the number of horns was reduced or increased?

What would I need to fabricate to make this work?

http://cgi.ebay.com/Federal-Model-5-Civ ... 16702316QQ


I'm guessing from the design that this one doesn't use horns. Would I just have to frame the thing out and mount it so to speak with an air intake "funnel/cone" going in the top?




Found these.. looks easy to make from scratch if one had the dimensions of the parts handy.

So a few questions if anyone can answer them..

I actually had to do some work today, sorry to keep you waiting.

No, that design simply runs an air compressor that feeds rotating blades connected to external horns. Increasing the engine horsepower is equivalent to charging your air reservoir more quickly. If it were a rotational open frame horn, then increasing the power still won't do much except allow you to get up to operating speed faster. The transformation of rotational power to acoustic power is incredibly inefficient. On the order of less than .1% of the engines torque directly contributes to the actual volume of the device. The loudness of the device depends on several factors: One, the tolerance between the rotating blades and the inner surface of the stationary frame has a direct effect on the amount of wasted air that passes through the gap. Also, if the physical distance becomes to great, then the acoustic loading of the rotating blades will create excess drag on the rotor and high pressure zones localized near the holes on the frame can interfere with the production of sound. The output of a rotational siren is maximally limited to the physical air pressure gradients which can be created by slicing the air and causing vibration. If you go too fast, you can exceed the devices ability to slice the air and thus you will have a cavitation effect by creating alternating vacuum and 2atm zones. It is equivalent to overspinning your prop in a boat. Two, the actual pitch of the device and the physical horn design and size need to be synchronized and designed together to ensure that the resonant frequency of your device does not fall outside of the useful frequency cutoff of your horn. The equal-loudness curve dictates that the human ear is much more sensitive at 4000Hz than it is at 400Hz (the frequency of the chrysler siren)... So, if you were aiming to be as loud as possible, you would want to design a horn and siren system that operates at 4khz, then duplicate it as many times as necessary by combining the output of all the smaller horns into a much larger sectoral horn.

I wonder what could be achieved with a 500HP engine. Those 50s engines while awesome as hell aren't quite as powerful as what we have to play with now. How would one change the pitch/tone?

Make the horns smaller and the rotor spin faster.

What would happen if the number of horns was reduced or increased?

More horns= more air capacity needed to drive them=more horsepower needed=more loudness.

What would I need to fabricate to make this work?

My guess is lots of stuff.

I'm guessing from the design that this one doesn't use horns. Would I just have to frame the thing out and mount it so to speak with an air intake "funnel/cone" going in the top?

The funnel is to reduce the impact of stray air going back into the device instead of radiating out into the surrounding area. Plus, it is mildly shaped like a cylindrical wave radiating horn when placed near the ground plane. There could be some small acoustic loading effect from having a horn/funnel shape on the top.

The most current version of this rotating siren is found on 80's firetrucks. The tolerances are so close that the metal on the outside of the rotor actually scrapes the inside of the frame slightly. But they are loud.

Interestingly enough, the creation of loud sound is more easily accomplished by putting a horn in front of a speaker. Large horns attached to very powerful speakers can easily create more sound pressure than this ancient thing. In the 40's, this was probably the only way to generate any sort of tone louder than 120db-- not so nowadays.
