Topic: [ANN] The world's first handheld Bitcoin device, the Ellet! - page 13. (Read 45670 times)

The iphone gets ham radio? Encrypted no less? Is there some Trucker CB radio app I've never heard about?

Please explain, on the surface that sounds ridiculous.

I guess it needs to be recharged at least once a day...

Do your calendar and clock require a repeater and other clock in a 150 meter radius in order to function?

I would like to point out that it's been more than a week.

A secret episode of bittalk.tv only available to ellet owners lol

Will it support ipv6? Launching a mobile device right now that doesn't support ipv6 would pretty much make it obsolete before even being manufactured. Although it would be a great upsell for later versions. Planned obsolescence and all that.

Come on, spill all the info, you know you want to.
Just how far along is it, anyway? It's been more than a week since it was supposed to be announced in a week. I see that the OP has been edited.

So what is this secret weapon I heard about before cut off from the chat?

I'm guessing it's a wrist watch? hehe

I'm not concerned with the IARU, it's the FCC that controls my license.


Nope, it's because it's the law in the US.


Digital radios can transmit the callsigns in their normal mode, so long as they are in the clear. In the case of modified wifi gear, this usually means in the SSID.
Again, nope.  Not in the US anyway.  The classic example is that you can't order a pizza over ham radio bands but you can over CB. Although bitcoin's protocol doesn't actually facilitate a business transaction, it's the result of one, so I don't know how it would work out.

seems legit

Ellet supports encrypted ham radio transactions with the iPhone CONFIRMED!

And that’s where I get the affirmation that transmitting encrypted through ham radio data is a bust. Glad we talked this out guise.

watching. will be great to see how this + bitcoincard develops..

Don't put it past me to include easter eggs like that.

You would have ranges where each value would be represented.  Say 34-35 represents 01101100 (arbitrary, don't try to figure it out).  You would have a tradeoff between accuracy and obfuscation.  If you broadcast 34.5 you'll have the best chance of falling in the proper range after your signal is corrupted by noise.  If your signal is strong enough and there is minimal noise, you can choose any random number in the range each time.  You could probably make it look a lot like analog noise if you tried hard enough, but you would have a tough time broadcasting over any distance.  Plus, the fact that your broadcasting noise would raise questions and it wouldn't be too hard to track down the transmitter to get those questions answered.

Most excellent, Matthew. 

Will it come with horse wallpaper?

Ill be watching this, good work.

exactly what i was talking about. i just could not put it into words. would such signal be detectable because of the "hops", like there is only 34 and 35 but not 34,5. would it not leave a empty "space" between 34 and 35?

You just need to quantize it, not necessarily binary.  For example you could take each byte of binary data, and map it onto an analog signal.  The low end of the signal would be 0 and the high end would be 255.  Of course, you will need redundant transmission and error correction because your analog signal will get distorted by noise.  The more bits you map to each analog value, the more problems you will have with errors.

I'm just going to briefly jump into this thread to correct some misinformation about amateur radio (ham radio):

1) the international governing organisation is IARU; not FCC

2) FCC is an obsession of the American radio amateurs. The reason for this is that historically most American hams held radio-operator positions in some military service. Most importantly they bring with them paranoia and indoctrination prevalent in the American military.

3) It is a violation of the amateur radio rules to transmit radio signals that require some secret to interpret.

4) Bitcoin uses cryptography for signatures, not for encryption. All information required to understand the transmissions is public.

5) Amateur radio actively encourages experimentation with the following disclaimers:

5a) don't interfere with other radio users
5b) identify your transmission in a way that can be discerned by ear by an ordinarily skilled radio operator using oridinary equipment
5c) publish all the technical information required to demodulate your experimental transmissions
5d) maintain (for about a year) the original text,voice,video,whatever used in your experimental transmissions and be ready to submit them to the licensing authorities
5e) there are additional restrictions on use of high power or wideband transmitters.

The rule 5b) means that every about an hour you have to transmit your callsign using Morse code or one of the classical audio modulations. In case of digital radio the Morse code doesn't have to be transmitted using unmodulated carrier (CW). It is sufficient to alter the parameters of your digital modulation in such a way that when listened on the audio the operator can by ear discern those changes and understand them as Morse code.

6) Amateur radio clearly prohibits for profit broadcasting and advertising. This rule is frequently misunderstood to prohibit any commerce or any monetary exchange. It isn't against the rules to facilitate person to person exchanges of value.

7) Politeness and common courtesy gets you far more in amateur radio than the strict obeyance of the rules and regulations.
