Cheap MP3 Broadcaster
Raffi Spock writes: "OK, this isn't new or anything, but with all that stuff on transmitters for MP3 that transmit through phone lines to an expensive receiver, I just thought I'd point the dial to Cana-kit who manufacture a little kit that transmits any audio source to a distance of about 150M. Cost is about $40 Canadian. I just built one of these, so I now can listen to MP3s without carrying a very heavy PC around. Oh yeah, since it just plugs into any audio output, drivers are unnecessary making it run on any OS."
broadcast-warehouse.com (in the UK) sells REAL fm exciters and amps. yeah, beyond what's legal in the US, but the audio quality is 100% full pro.
and if you're worried about too much power, just transmit into a dummy-load (50ohm resistor with enough wattage to take the output, at least 5 watts non-inductive).
the ramsey kit (fm10a) is very well known and famous, but has spurs that, if amplified, will make you quite illegal. I opted for the synthesized broadcast-warehouse system since its known to be much cleaner (rf wise) and you have more options on the audio front-end.
but be prepared to spend at least 2 hrs per kit to build it...

Napster-to-go says "Fill and refill your compatible MP3 player", which is a lie. It's not MP3. It's WMA with DRM.
The register had an article a while back about Psion bringing out a Digital Radio which will have the potential for fast internet access
Allegly the BBC here in the UK(according to this article in the register) will be doing just that in the not too distant future, hook the radio to your PC via its USB port and forget phone lines becuase in theory you could recieve data at up to 1.5 Meg per second.
Let's see... $20 canadian, in the US, that'd be worth approximately...

Check this one out. Cool or what? Too bad it's way too expencive, I wonder who will buy one for $250?
The idea is great though, use your old cassette players. Second bad thing is that it can only hold 30min of music.
They don't say how much the flash addon costs, but I bet it will be expencive also.
Oh well, bed time, night folks!

Whoopdey-doo! Audio transmission...pretty new. Lets make some other 'new' interesting items to feature on slashdot...
(1) MP3 Phone - Simply place our specially designed handset near your PC speaker and transmit mp3's across the world at the same quality as realaudio but without glitches or buffering problems!!
(2) MP3 PPP - With our advanced audio technology, you can transmit audio to any point in your building without terminating any cables!!! Simply place our patented TransCan(tm) in front of your audio speaker and the RecieveCan (tm) at ear or microphone of recipient. Pull the string tight and you have clean uninterrupted MP3!
(3) MP3 Wheel - This new Solid Object Design (SOD) is designed to roll much better than a normal square cement slab thanks to our super advanced manufacturing technology. It doesn't play MP3, but I figure that if you put those three letters in a post, it somehow becomes relevant.
'When I was young I prayed to God for a bicycle.....Then I learnt that God does not work that way - so I stole one and asked him for forgiveness instead.'
Can't get to the website due to errors over there, but if this kit is based on the BA1404 chip like the Ramsey FM10 (which, for this price I think it has to be) you may have serious problems receiving what this thing puts out on many FM receivers. The BA1404 uses a tank circuit (an inductor and a capacitor) as the part that sets the frequency, and this can drift really badly. Many FM recievers today are PLL based (if it has a digital display, it probably is) and can't tune in an analog sense. If the signal drifts off of the FCC "channel" (they go in 200KHz increments, starting at 87.9 up to 107.9), many receivers won't, and if they do at all you get a really noisy signal. An FM discriminator can pull in a signal a few KHz, but they are generally designed to work within the frequency specification that FM broadcasters are mandated to follow by the FCC, which is *much* smaller than the frequency precision an L-C tank will give you.
There are FM transmitters out there that don't suffer from this problem- they use a crystal controlled PLL circuit to set the frequency, Ramsey sells one. But it is much more complex, and more expensive (I think Ramsey's is about $150)
Isn't this the same thing as a Mr. Microphone? They used to advertise them on TV for kids. It was a microphone attached to a small transmitter that you could pick up on a regular FM radio between normal stations.
"Hey good lookin! Be back to pick you up later."
Software sucks. Open Source sucks less.
At my work, a bunch of us have 900Mhz wireless headphones
900Mhz ?
Was that before or after you overclocked them ?
X-10 also has a "DVD Anywhere." In reality they're the same product. So while I've never used mine to play MP3's, my experience with using it to play DVDs might still apply.
I used my DVD Anywhere to transmit DVD video from my PC to a TV screen over 24 feet away. The image is crisp and clear and the audio sounds great (except for some static when someone walks between the recievers).
The remote's a pain to set up, but mainly because it's designed to be extremely flexible. Once it's set up, it's easy.
Like bluestar said, it's $80, but they seem to be running a deal where it's only $70 (plus free shipping). Apart from some stuff for the remote control, I don't think there was any software to install to get the MP3/DVD transmission functionality working. So those of you running Linux boxes wouldn't have to worry about Win9x-only software. (And they have a Linux-version software for another of their products, so my guess is, they'd provide Linux software if the demand was high enough.)
My sci-fi novel, Ghost Thief, is now available from Amazon.com.
They use NT, to judge by the error message (characteristic of IIS) and all the .asp files on the google cache page's hyperlinks...
Yet another example that NT blows. (note that it isn't a bandwidth problem or else we wouldn't be able to get to the server at all)

You could then hide the "station" somewhere where it can't be linked to you, and see how many people start to listen to it before the FCC finds the box and shuts it down.
The possibilities are endless. You could set up "phone in" competitions using GOP telemarketer numbers. You could spread news and rumours (ie "And I've just been told that KFCs all around the city are going to give out free chicken to anyone who comes in within the next 30 minutes and says the words 'I'm a chicken, cluck cluck cluck' to the cashier".
I mean, wouldn't that be cool?

Similarly, they sell a video transmitter that broadcasts to channels 2-5 (I think) so one could broadcast there Divx;)'s to other rooms of a house. I believe the unit costs around $150. Sorry, don't have my cuecat (blah!) to check the price out (it's been dismantled). :)

That's the same as most cordless phones. Yes, it's 900 MHz. They also have 2.4 GHz phones.. It has nothign to do with clockspeed.. It's just the carrier frequency of the signal.
imagine a bew.. oh never mind
.sig (insert funny sig here)
The technology has nothing to do with MP3. Much as how people say they use their minidiscs to play MP3s when in actuallty their listening to their MP3s reencoded into ATRAC, the term "MP3" has not hing to do at all with what's really happening.
A headline "Cheap Radio Transmitter" would have been more accurate, and it certainly would NOT have been news. Music over radio is certainly not new technology, and after the transistor became popular and cheap, broadcasting inexpensively became a no-news issue too.
No offense to anyone, but I think that slashdot has been suckered into giving this company free PR.

what I've wanted for along time since I rent running CAT5 is not an option but now I can listen to MP3s in another room without having to run cables or buy new hardware. This is very cool.

I just built one of these, so I now can listen to MP3s without carrying a very heavy PC around.
Laptop, portable MP3 player? Sorry, but I don't really see the use.
People replying to my sig annoy me. That's why I change it all the time.
Actually, it was a Canadian (Fessenden) who invented radio as we now know it. He was the first to transmit an audio signal through the air. Before then, it was all morse code.
:-(*
I definitely have to agree with you on the Mims books, though. I learned sooo much from them when I was a kid. I even remember going to Buffalo, NY to get the 3 mini-notebooks that weren't available in Canada at the time. For some reason, back then, there were three exclusive to the US, three exclusive to Canada, and three you could get in both countries. Now they're all available anywhere and there are new ones. I also highly recommend his "Getting Started in Electronics" book and the new flashy ones, "Basic Electronics," and "Basic Digital Electronics," written by other people, as well.
In fact, buy every book in that store. Nowhere else can you easily get excellent beginners electronics books for so cheap, especially since McGraw-Hill stopped the book clubs.
I built one of these using an cheap fm broadcaster from ramsey electronics. http://www.ramseyelectronics.com It works very well and did not costs 40 bucks.
Only 13 comments and thier webserver is already a smoking heap on the side of the road...
You can find a excellent comparison of Ramsey's and Cana and other exciters/low power transmitter kits here.
RADIO!
I hope they don't patent it.
Seriously, go to the library, get out a book about hobbiest electronics, then go to Radio Shack and buy the bits for five bucks or so. Hell, buy the book at Radio Shack for a $1.99, Engineer's Mini-Notebook-Communications Projects, by Forrest M. Mims III.
You might even, God forbid, learn something in the process.
What does this have to do with mp3, exactly? It's an audio -> FM transmitter. very common, you can buy kits all over the place, and have been able to for years. Same stuff old (and new) CD changers work off of.... very simple circuit to build yourself.
How is this news?
Sorry Yes I knew the 900 Mhz was frequency not clock speed... but I couldn't resist, call it the lure of the dark side. You spend all day on a computer, see 900 Mhz in a post, and go on admit it, the first thing you think of is over clocking!
i wonder what kinda heat sinks he has to throw on them to get them to 900 Mhz ;)

Since you don't really care about quality of the music you are broadcasting, and you don't seem concerned about the range, why spend the money? Use a better hack and transmit AM with your monitor!
Don't buy it -- It's an evil canadian trick! Think about it... what does Cana-kit most sound like? That's right: Rootkit! Even worse, what's its main purpose? To transmit.
But wait, you say. It's just transmitting music.
Ah ha! That's what they want you to think. While it may be sending music on one channel, this is only a front. Its _real_ transmission is on a much lower frequency, right above the 20m ham band. This enables it to bounce signals off the atmosphere and RIGHT INTO CANADA! They're secretly sending all our root passwords to canada!
In sum, I encourage everyone to boycott this nefarious scheme. We Americans control the world and it should stay that way. G-d bless apple pie and the American way!
Of course, one could also argue that Slashdot is a DDoS tool. The master (CmdrTaco and the rest) order the "zombies" (eheremm, us) to attack a site (our poor little mom and pop businesses that get posted on the front page o-so-often) and takeit offline.

That's a beautiful troll. Very subtle the way you bring up Canada, and thus a possible flamewar. Also the implication that granny could die from one of these devices was masterful. Very accomplished, and carried out with aplomb. Keep it up!
Nope according to the frontpage they are more than happy to ship to the US. The key is range. The microwave could kill Grandma also. As low power as this bad boy is it would be fine with the FCC. This is the same thing as those mike/radio things that Homer got for Bart that one time. :)

At my work, a bunch of us have 900Mhz wireless headphones that we use to listen to music (clotheslining yourself while rolling around the lab sucks). The cool thing is that we can all tune into eachother's frequencies. So in a way it's kinda like we have our own mini radio staitons :)

And remember, if you bring your clocks over to this country, you need to modify them to count from 0.0 o'clock to 9.99 o'clock metric time in one day, or else you'd miss the train.

(back on topic) Canadians going down to the US: Don't forget to ditch those 900 Mhz scanners. In the US you are only allowed to listen to portable phone conversations, and not cell phone conversations, since this makes all cell phones much more secure. And don't even think of mentioning the NDP party down there. You Canadians know what I mean.
For Americans coming up to Canada, don't forget to ditch those radar detectors, since in this country those are banned. But why would you need one anyways? The land up here is too rough and barren to drive over the limit anyways.

No, because if I get a link to my site posted on Slashdot, I'm going to squeeze out every banner impression I can. This is the single biggest reason why caching will not work in this application.
So? Cache like google. No url rewriting, or at least no tag rewriting. That way, your banner will be still be viewed as much as possible, but /. takes the burden for the pages. As long as your ad-server can handle it, you get all the impressions you want...
The big problem is legal. It's mirroring without permission, which may or may not be illegal (I'm not touching that one with a ten-foot pole).
Someone mentioned the 'Win 95 compatable' power strip. Also known as the 'plug & play' power strip.
Also, I've seen plug&play UPS units (though they arent' actually manageable, so they act like a power strip).
Then there's the 'soundblaster live mp3+' which is really the exact same hardware as the 'soundblaster live x-gamer', and the 'soundblaster live value OEM (though the oem one is missing 1 smd resistor pack and the digital CD in, but you can add them yourself).
Then there's 'digital ready' headphones.... that's funny. let's see.. what else....
or like 'Cholesterol free' or 'Fat free' bran flakes during the cholesterol retail wars.... yeah. They were ALWAYS fat free. Funny.
There are a plethora of 'plug&play' and 'windows XXX' compatable serial/keyboard extender cables (just cables.. not active components).
I know there was an even dumber one I saw.. I can't recall what it was, it was so dumb. Something like a keyboard dust cover or something that was 'win98 compatable'.
Of course, there's the new buzzwords too, right?
