Working SONY Multiscan Projector VPH-1272QM direct ready to create your home cinema.

With the proper graphical card you can use it for HD-TV, HD movies, HD games and business presentations. Details are H-scan 15-85 Khz, V-scan 38-150 Hz, RGB bandwidth 75-Mhz, resolution until 1600 x 1200. Size 65 cm wide, 80 cm deep and 35 cm heigh, weight about 60 kg and has handles for easy transportation. Serial number is 5000586.

Can be mounted on the ceiling, including power cable and extensive control panel and remote control with identical extensive functionality. The projector (beamer) can be used on surfaces up to 4,5 m screen height, optimal viewing distance is is 2,4 m to 20 m. Extensive manuals and help can be found on-line and in this forum.

The reason I am selling it is that I don't find the time to create a home cinema. I hope some else can enjoy this wonderful machine.

I will throw in a new VGA cable for free that costed € 15,-. The total price is only € 225,- and you will have to collect it at my home in Utrecht, the Netherlands. In BTC I will charge the intemediate market exchange rate to EUR of day of sale, which on September 6th is just over 40 BTC.

OptionallyI have also a new projection screen for sale which is 175 cm wide and 132,5 cm heigh (218,8 cm diagonally). The brand is ACCO Nobo and it rolls up towards the ceiling. The price for that is € 85,- but if you buy the projector I will give you a discount on it.

Hi all, if you agree, please merge all serious proposals and requirement for Bitcoin sign here: https://en.bitcoin.it/wiki/Bitcoin_symbol#New_Unicode_symbol in order to have a clear and high quality overview in stead of them being distributed over many long posts. Of course the posts remain useful in discussing proposed Bitcoin signs.

The implementations of the glyphs and optional alternative glyphs are completely up to the designers. Example for euro can be seen here where the first series contain text figures, non-lining numerals or old-style numerals and the second series contains lining numerals or titling figures.



Note that most fonts only have one of the two versions and that is at the same time the default for that font. High quality fonts or fonts in which attentions has been paid to this aspect have both. Apart from the numerals also dollar, cent, euro and pound sterling can have two versions (sometimes also for the percent and ampersand glyph). The versions are mainly concerned to the normal or full height and positioning below the baseline or exactly on the baseline.

As seen in this example, some features can change. For the dollar, this is usually observed in one or two vertical bars. For Bitcoin you can choose what to change if there is an absolute need for it that has been observed in its usage. Otherwise it is best to keep only on version and only change the two aspects as height and positioning on or below baseline. So yes, only minor variants!

As for which is the official bitcoin character from which I make the an reference character for Unicode Consortium, please let me know which one it is. I will not be a part of figuring that out and will use whatever the community comes up with. I think a poll is not a good idea since most community members do not have enough experience and proper frame of reference on design and typography relating currencies.

Best is to have the community to appoint three of five people that will look into all suggestions, pros and cons and decide what it is going to be. That will be the version we will stick by. Note that this has to be well designed and chosen (both for digital use and handwriting). It would be a success for Bitcoin of course to get a Unicode assigned.

So let it be one of high quality. If you have a committee of three or something we can also as some open source typographers to have a look at the current proposals and perhaps they have some good feedback or improvements.

As far as the copyright, the copyright of the logo's is enough. They want to make sure we are not trying to insert some symbol that is proprietary or has copyright or trademark by a party that does not allow use of it freely. Who can help me out with this by contacting the authors of the official logos?

The #-B is perfect as a compose key sequence for bitcoin sign like C= and =C are for euro sign €. Alternative compose key sequences can also be B# and #B. I will come back later to this at the end of this reply.

As I explained wareen, the symbol submitted to Unicode Consortium is only as a reference implementation to assign a character code. That particular glyph is in the style of their typeface (which you cannot use, except for reference in http://www.unicode.org/charts/PDF/U20A0.pdf so it should be as generic/boring as possible). It is up to the font communities such as Latin Modern, FreeFont, DejaVu etc. to come up with their own implementations in the style of their typeface once a unicode has been assigned.

For example the euro has an official symbol, but not many fonts are using it because it doesn't fit the style of their typeface. Hence, designing a bitcoin symbol that all should use will also not work. Just have a simply and clear description of that it should look and leave it up to the typographers to make a version in the style of their typefaces.

In fonts it is possible to have two implementations of a currency sign, like the dollar with one or two bars. One is in the lining numeral range and one is in the non-lining or old style numeral range. This could also be used for the bitcoin signs to offer an alternative glyph. So you have the B| and the B#. As people have mentioned, B# is written as a 3 plus a hash and the B| as a B with longer vertical stroke and a (sometimes partly hidden) bar (like B for bitcoin and bar as in a writing dollar). For that reason I prefer the B| because in the the process of writing it associates more with bitcoin and currency.

For the Unicode Consortium, there has to be one reference character and not two. Of course each font can make their own version to match their style but this is unrelated to the reference for the unicode. Because we (here) communicate mainly digitally, the advantage of a written bitcoin sign is only now appearing with B# compared to B|. That is all fine an can be a possible implementation for a certain font but the community or the maintainers have to decide on the official glyph, but it has to merge to a definitive official character/glyph. The logos and artwork on the other hand all use B|. In short, in the proposal to the Unicode Consortium I have included a SVG version of http://img228.imageshack.us/img228/4500/bitcoinsign20110719.png which is in the style of the Unicode Consortium font and not an official version from the community, only a reference to the concept of the official bitcoin character. I used this one as the official version to create this serif reference character and aligned the bars to what is common with other reference currency signs in the Unicode code charts.

If the official bitcoin glyph has changed in general make up, not in details, please let me know and I will amend the proposal.

Wanted: scans or photographs of actual use of the bitcoin character (B with two lines of which the second one is only visible outside the B, see image below). Note that this refers to use of the character or glyph for bitcoin in texts, not the use of the logo in artwork.



The sources can be either printed press or actual handwritten text.

Please upload these files to e..g http://imageshack.us/ and post the URL at http://forum.bitcoin.org/index.php?topic=7215.msg105833 This will be used to finalize the request for a Unicode at the Unicode Consortium. The request has already been made but more real word examples have to be provided in order to resubmit the request.

Good that a part of the commuinity is in favour of using the actual bitcoin sign.

The request for a Unicode for the bitcoin sign is halted at the Unicode Consortium until the community can provide the following:

• statement that the bitcoin logo/glyph is open/free (e.g. that it has the MIT License like the software)
• collection of examples of actual use in publications or handwritten texts of the bitcoin glyph (please send me digitals scans / photographs)

If the community can provide me what is listed above, I can resubmit the proposal at the Unicode Consortium to get a Unicode assigned. Please ask some of you community friends if they can help out too. Please post links of the scans or photos, e.g. via http://imageshack.us/

Hi all,

I just got the following answer from the Unicode Consortium:


So, can someone from the core developers provide me with the license of the bitcoin currency symbol and with several examples of running text so I can resubmit the application?

Thanks,

Pander

Also added BTC as non-ISO curency on Wikipedia https://secure.wikimedia.org/wikipedia/en/wiki/ISO_4217#Without_currency_code

Many currency codes can imply a different interpretation. Just stick with BTC as it is not used by others and used extensively throughout the community.

For people that would like gnucash to support BTC, see https://bugzilla.gnome.org/show_bug.cgi?id=648627 for contributing a patch providing BTC as a user defined currency.

After positively challenging all four points, this is what I got back, unfortunately:


Perhaps when Bitcoins are more mature and the market has grown, I hope they will pick it up by themselves.

I got the same reply.

1: agree, EUR is a good example
2: it is not privacy because everyone can use it, there are no conditions to exclude anyone so it is public
3: agree it is international
4: OK, well that is the power that it has no single point of failure, but that doesn't mean it is not a currency. However, it has a market, just a matter of time it is on Reuters and Bloomberg. We could ask Reuters http://reuters.zendesk.com/home and Bloomberg http://www.bloomberg.com/about/contact/ to also report on the market figures from http://bitcoincharts.com/markets/ Who has any idea how to go about that? Who is willing to take up that one?

Please challenge SIX Interbank Clearing (in a positive way) on all points. I will do the same.

that too indeed

You can configure X.org/GNOME to generate a Thai Bath sign for a 'B' and '|' with your compose key. But note that that is Bath and not Bitcoin so I would not recommend that and put effort in getting support for the actual Bitcoin currency sign.

Once Unicode has assigned a code for Bitcoin, a B with two bars van be generated via the proposed compose key combinations mentioned earlier.

Already a many currency signs exist, see http://www.unicode.org/charts/PDF/U20A0.pdf plus the 20 that are in other Unicode ranges. Even https://secure.wikimedia.org/wikipedia/en/wiki/Currency_sign is listing over one hundred currency signs. Bitcoin has a currency sign and as the currency matures, this might as well be supported by Unicoded, I think.

Hi all,

Please help in requesting Unicode Consortium to support Bitcoin currency sign. If a Unicode has been assigned, free and open fonts can start implementing their own glyphs for the Bitcoin currency sign.

I have made a request two months ago, but haven't heard since from the Unicode Consortium. Perhaps some extra (digital) requests can motivate them more to start supporting the Bitcoin currency sign.

See the following procedure:
  http://www.unicode.org/pending/proposals.html
to fill out:
  http://std.dkuug.dk/JTC1/SC2/WG2/docs/summaryform.html
with the help of:
  http://std.dkuug.dk/JTC1/SC2/WG2/docs/principles.html

Below are details of what to include in the request:

http://img5.imageshack.us/img5/4017/99838698.jpg

Composite sequences, inspired by euro composite sequences:

b=    (b + equal sign)
B=    (B + equal sign)
=b    (equal sign + b)
=B    (equal sign + B)

Please contact me in a personal message to send you the .SVG with the glyph as the upload folder of this forum is full.

gnucash maintainers told me to make this request as they will not support it otherwise. see also https://bugzilla.gnome.org/show_bug.cgi?id=648627

In order to get Bitcoin currency code BTC more widely supported (e.g. Unicode, gnucash, etc.) please request http://www.currency-iso.org/iso_index.htm via email on office@currency-iso.org to add BTC to the ISO 4217 list of Currency Codes. Below is an example email (please improve the text with some motivation if you like).



Dear madam, sir,

Please support the new Bitcoin currency code BTC in ISO 4217. For more information, see:
