um, ziplock? :)
Actually, MP3 players are still more expensive than CD players, but you can have something that doesn't skip and they are way smaller (you could keep it in your coin pocket). I wouldn't wear one scuba diving tho. :)
How are you at humm>>Y not an MP3 player without moving parts?
are you able to wire up the personal mp3 players into larger speakers and plug into a 12v power source?
lol.....thats just....mean. ;-)
Snorkel and a winch first....
And a sealed plastic box for the stereo with poly speakers. Marine shops have some interesting containers and you can make a sealed exit for the cables. Or improvise with a tupperware container and duct tape as a second seal....

86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT'sThe more I drive it The more I'm amazed. I owned it 8 years now I've driven it over dead fall trees,logs,branches and browse. Trail? We don't need no stinken trail (Seriously)
Through loon s**te swamps (you know, when you sink up to your knees/crotch in it)
Crossed lakes,ponds and streams.
As for rocks... Well it's like any machine. Put the wheels on the highest rocks to climb over or go around.( I don't climbs rocks for fun) I have a skid plate on it so scraping over rocks is no problem. traction is no problem as it's a skid steer when one side starts to spin just brake it and the other side drives it out. I wish I had pictures of it in action.
With the super tracks, it also traverses deep snow (I don't have tracks as I have a Ski Doo MXZ)
I use the machine only for hunting season in the Calabogie Ontario Area. Mike Romain kinda knows the area as it in the same general area he wheels in the fall.
Granted some th> >
I have no clue.... I don't recall ever reading it either. The manual spouts thd, +-db etc but I don't recall seeing the sampling rate. I have an Alpine that sucks for skipping, bought some Pioneers for work and they were surprisingly outstanding but I've never had my Mac skip until about 35 mph on a rough trail/road... almost washboard. Still pretty impressive for me. Just the vibration of the 660 might be enough to skip a CD. twaldron has the right idea... mp3

Most use a lower voltage, so you could use a downvertor from RatShack or equiv for power, and then use a set of powered speakers. Best model to get is one you can get a software driver for, say a free one from RealAudio.

Oversampling doesn't prevent skipping, has nada to to with it. Most oversampling is just used so the D/A can be done by a 1 bit pulse width modulator rather than the far more expensive linear PCM D/A.
It would be possible to help skip protect by rotating the CD faster, as is done in a computer CD-ROM deck, and then if you miss a sample hope you can spin it around again and get it on the next rotation. Dunno anyone doing this as opposed to just making the pickup extremely lightweight.
MP3 is really more convenient anyway, as you can get more music on a CD. You wouldn't really need such fancy features as variable bit rate 320+ Khz sample rate in a automobile unit, since it would be a waste. Anything that can play a standard data CD at 128 Kbit or better should work.
Kenwood has a CD/Mp3 player in dash unit and there are probably hundreds of others.
My suggestion of the MP3 is so that you could take it with you. It would be non permanent. If you want a more "installed" setup, you could use an in-dash, or experiment a little. The only output on most MP3 players is the headphone/earphone out. That isn't enough to drive a set of speakers without some sort of amplification. If the speakers were self powered, you might be able to do that. Some CD players have a speaker out or LINE out.
In our Jeeps, we could run the headphone out of the MP3 player into the CD (AUX) input on our stereos. Headphone is not quite LINE level, but it will get you close enough to play it. I imagine it would not have the full volume of the radio or CD player tho. There are companies that make adapters for that very thing and will bring the earphone LVL up to LINE.
Well most ATV's and the Argo is an ATV don't need a real trail. But they need it to be clear of lots of vertical trees. :) That shurb brush can rip you up pretty good.
Yep, I know it and avoided it in maine when I was up there years ago.
Looks a bit iffy on the depth you have to the top of the damn there is a nautical term for it and it slips my mind! Anyway you don't have a lot of room before water comes in and you need a bilge pump. They send me the catalogs every couple of months and while it can cross dead water. Anything amounting to chop would be scary.
Well what I really meant was it does not look like it has a lot of articulation in the wheels to go up and over some of the rougher stuff. To me it basically looks like a variant of the M29 weasel which was also amphibious but the Weasel had a problem in that while it could chew through stuff that would kill a jeep it has metal tracks and was a pain to drive with a 3 spd manual studebaker tranny. I'd love to seea video of you putting it through it's paces. I won't ever be able to ride a Quad agaid so the Rhino is looking mighty good and I'll be interested to see what Nathan says about it's capabilities. The Argo's can only go 24 mph or so. I guess there is another company out there that makes a similar ATV to the Argo but it has up to 8 driving wheels and is amphibious.
I wonder how well those tracks would actually work since they stay on all the time. It might climb hills a bit better with tracks.
Quads are fast and it would be nice if they could double the speed on the Argo. But the ground clearace is low with little articulation. So big rocks are out but being amphibious is an asset if you have to go through standing water. I wonder how well it will pull itself through real Mud tho. Dealers never let you actually play with one. Is teh only reason the Quad can't make it up to you camp is because of deep standing water?
I'm not trying to give you a hard time. I just am curious since my quad riding days are over and I'd like to find smething fun. Speed is good too tho.
already routing the snorkel through the roll cage, and a 3000 pound ramsey is on my christmas list.
hadnt thought about a marine shop. come to think of it, dont they sell waterproof radios that dont require anything further?
ive met a few argo and argo type rigs on the trail in 6x6 and even 8x8 configurations. theyre a great all around machine, but my experience with them has left me with the impression that they arent at home in rocks. im not talking about crossing a rock here and there, im talking about in more aggressive areas like daniel at uwharrie, or anywhere at tellico. while you can make it go, it seems to require far more effort than i would want to put into it. skid steer just is not effective in off camber rocky situations.
or maybe it was just those particular riders.
you talking 4x4 quads? unless youre referencing floatation......
so far im amazed by this machine. the proof lies in the rocks though, and thats coming this weekend.
my '01 arctic cat 500 4x4 manual runs out about 52mph....58 with the "normal" tires on it. there are many faster machines, but i prefered the low end torque of the cat. now they have the 650 vtwin cat that gives you the best of both. another option is the polaris ranger. i was going to get the ranger until yamaha announced the release of the rhino about 6 months ago. both are great machines, but i went with the smaller rhino because i dont like the polaris front drive system. it works like "auto" 4x4 on the expedition. if you put it in 4x4, the front wheels dont pull until the machine senses rear wheel slippage and then it locks them in. when there is no more slippage, it releases the front drive. i would have gone that route for the benefits of a side by side, but im glad now that i waited.
? i thought oversampling was where the player reads ahead and plays from memory therefore reducing skips?
Approximately 10/22/03 15:44, Nathan Collier uttered for posterity:
No.
The only way you could read ahead is to spin the disk faster than the music rate. Don't know of any music player or even CD-ROM that does this when playing the data as music. Ripping CD-ROM's of course do overspin, but that is recovering the music as data, not music.
For skip/loss issues, a music CD has it much easier than a data one. The music is group encoded and interleaved such that the player can actually lose one entire group sample and still be able to recover the original signal 100%. And if the loss is beyond the ability of the player to recover from error and group encoding, the player will typically interpolate the missing values. [Muting will either produce a pronounced "click" or will cause more audible effects than simply interpolating.] Engineering opinions vary on what to do if the music track is lost, some players hold the pickup exactly in place and hope it is recovered. Some do that at first, but then slowly move the pickup outwards, hoping to pick up the next track. [not song, just the linear track] and recover a better clock. For a player that gets moved a lot, first you make sure the playback mechanicals are really really light weight, so they are more immune to being jarred out of place. Then you add a few Megabytes of FIFO memory in series with the data. That way, if you drop the signal at the pickup end, you can hopefully recover it and stuff it into that FIFO exactly where it belongs before the FIFO empties out. This memory is what really helps a moving type player handle shocks... it doesn't handle them, it just cheats and uses the data as it comes out of the FIFO and hopes the pickup manages to wander back into place before the memory is drained of music.
Oversampling is used to make it easier on the D/A convertors, whether multibit or single bit. Oversampling consists of [and this is oversimplification] simply sampling the *same* sound sample multiple times. 2x to 16x or so oversampling usually means that the player has a linear D/A of which there are cheap ones and very good ones but not both. This oversampling can help with clock recovery issues as it is extremely important that the digital recovered data be fed to the convertor at exactly the rate at which it was recorded [nominally 44.1 Khz] and that the successive clocks do not vary as far as when they are used to clock the music sample. Anything over 16x Oversampling with a Linear PCM D/A is marketing fluff. Oversampling rates of 96x to abou 256x mean that the D/A is pulse width modulated. In other words the analog signal is created by simply switching on and off a single bit at many times the original music rate, then integrate the result and viola.
Don't know how "waterproof" you can make a CD player, but I replaced my stock CD player with a Jensen marine AM/FM/CD, model # MCD6424RC. The circuits are all potted and the front cover does a pretty good job of sealing out dust and dirt infiltration, which is how my stock CD player died.
That's buffering.
I am not sure, but I believe they sell the waterproof containers for radios.

This is what I am wondering about Nathan. I know of relatively flat surfaces it should have no problem but it doesn't look like it has a lot of stretch for the wheels over big gaps and the ground clearance is about 6 inches or so. That's not to knock it it's just that I'm wondering about how it will work for my needs. Also I wonder how well it can climb hills at only 24 mph top speed. If you run out of grunt there's no where to go. Be nice if they upped the power and speed and gave it some articulation.
Well it looks damn good for most uses although rocks can be very slippery. So I will be interested to see how well it fares.
Soo I think around 50-60 mph is a good speed unless you are on the highway with all the other commuters. The Kodiak 650/700 looks like a decent quad for a swing arm. I don't know how well they will implement their IRS. But My back cannot handle the position I'd have to be in on a quad. I believe the Cats are using the Kawi engines now.
The Ranger looks pretty rugged but the specs on the Rhino seem better. Still I wonder how well the Rhino will perform in mud and water. Mud always seems to be the toughest on ATV's.
I don't suppose you'd care to take the Rhino through some decent Mudholes while you're out? :)
you and me both! expectations are high with my goal being to find its limitations.
most of my riding is below 20mph. the only time i run faster is if im driving on the highway to the trailhead (which you arent supposed to do anyway).
since the swing arm has _zero_ articulation, i would avoid swing arm quads if you have any plans of riding rocks. sure they do it, but most of the rollovers i see are swing arms in rocks. other than off camber crawling the swing arm will do fine. in fact, it can make for a "zippier" quad on twisty trails because there is no lean in corners. its also better suited for heavy work. arctic cat had everything up to '03. their "ACT" suspension was a live axle on coil springs with upper and lower control arms just like a tj has. it was perfectly suited for work and articulated like nothing else. i cant understand why they dropped the ACT suspension for fully independent. well, i understand why......the market was heading in that direction.....but the ACT should have remained an option like it was in '02. ill be hanging on to my '01 cat for a long time i think.
i think thats why SxS (side by side....as in rhino/mule/ranger/gator) are becoming so popular. several of my relatives now have rangers instead of atv's for that same reason. course now theyre talking about looking into rhinos. :-)
cats have always used suzuki engines until this past year when suzuki and kawasaki merged. it worked out too, that v-twin kawi 650 is an awesome engine. theyll still use the suzuki 250/300/400/500 and then the kawi 650.
the ranger is rugged.....its one hell of a machine. while the specs on the rhino are a little better, it really depends on what youre looking for. the ranger fits 3 people easily with seat belts, the rhino 2. its almost impossible to roll the ranger over simply because of its massive width. we've had my brothers 6x6 ranger
theyre both great choices for work or play, with the rhino doing a little better in the play area and the ranger doing a little better in the work area.
we dont just have mud around here, we have swamps with really big gators. :-) i had it in the swamp yesterday and i was _really_ pleased. i didnt get as far as i can get with my arctic cat, but my arctic cat weighs half as much and is running 26" x 10" vampire mudders (by interco/super swamper) front rear and the rhino is running 25"x 8" front and 25" x 10" rear rawhides. although i couldnt get quite as far in the boggy swamps, i never needed to get towed out. i could always back out on my own power. in all fairness i feel i could have done better had i gone WOT and slung the mud a little harder, but WOT isnt an option until after 20 hours. i think the rhino could follow the cat in about 90% of anywhere id want to go. it was only when it really gets bad that forward momentum was lost. fwiw, my rubicon wont get down the road that leads to the bog, so just getting to the bog impressed me. ill probably try again after breakin.
