Good idea, I will order airtite capsules (with foam inserts). They are pretty cheap and I think they will be better than plain capsules.
Plain ones of the correct size will be less likely to make the silver tarnish as there will be less air and the foam may not be inert. Also get some plain cotton coin gloves for handling as sweat and grease will also make them tarnish (i.e. the less handling the better) |

I would be interested in 2 of each. Total would be 6.6 BTC + postage (I assume RM Special Delivery)
2x 1 BTC / 1oz coin
2x 0.5 BTC / ½oz coin
Same. Would you mind doing what the other group buyer did and order some of the coin cases from eBay at like $1 each? I'm in UK. Let me know when you want paid. +1 for coin capsules I just checked on ebay and 20 coin capsules cost £5.60 which is 28p per coin. (Does anyone know the width of these coins?) |

I have made some UI improvements to the version supporting user provided private keys. By default the field to input custom private keys is hidden. If you check the box to use custom keys the field appears along with some text explaining how to use it. BitAddress fork 0.5Functionally it is the same as the 'dougie' version. I've implemented all the functionality requested by casascius and will leave it at this. I'm still open for suggestions/feature requests though. Thanks - I have played with it for a bit just so I could produce the photo below. I found a bit of difficulty on the sheet of labels I had, horizontal spacing of the labels differed from vertical spacing. It might be a good idea to make them two separate settings. Anyway here is a photo of some coins. There are roughly 500 in the bag.  How does my version look when printed? https://bitcoingrid.com/jsprinter/jsprinter.v0.1.html |

This looks great too! Same on the circles, any way to not print them? [/quote] Just untick the "Show Circle Outline" box (top left) |

Great work! Was testing, then my printer run out off ink on the first sheet!  In other news, you finished the job faster then it took me to get the labels! Please let me know your public key so I can 'buy' you some labels!  Same goes for the next person to finish. The one problem I did run across was the "change your paper size" text was acros the labels if using small margins, but these could be edited out. Just delete line 10401 or do a ctrl-f for this and just remove it doc.text(10,4,'When printing use the "actual size" option and change your paper size to '+ base.format); I will make it smaller in v0.2 |

This makes mini keys but uses the javascript random number generator which is not good for cryptography i tried using the BitAddress SecureRandom function but i cant understand how it works. Can someone have a look at this? //This code unsuitable for cryptographic purposes due to the use of Math.random();
//Bitcoin Grid - bitcoingrid.com
generateMiniKey: function (){
var possible = "23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz";
do{
var key = "S";
for( var i=0; i < 29; i++ ){
key += possible.charAt(Math.floor(Math.random() * possible.length));
}
} while (!Bitcoin.ECKey.isMiniFormat(key));
return key;
}

The 29mm labels are going to be the best fit on the coins but probably going to be harder to find in the US where 1 inch (25.4mm) is far more common unless someone wants to pay expensive shipping from outside US. Ideally it should work with any labels - someone should be able to figure out the numbers for their particular labels and then hit print.
The send many command also needs to send to the Bitcoin address not the private key (starts with 1 not 5) and also needs to be a comma and space after the amount.
Also this would work so much better if it could generate the 30 character minikey and not the full length 51 char privkey. Mini keys are easy to generate, just generate 'S' plus 29 random alphanumerics in the base58 set, do a quick sha256 test on it+'?' (only 1 in 256 codes will pass the test), and increment or regenerate the code until you get one that passes. When you have one that passes just take sha256 of the string and use it as a private key. Minikey is described on the Bitcoin wiki and redemption is well established since I use it in Casascius Coins. I am willing to pay this bounty out more than once and would love to see bitaddress modified to make minikeys.
Just generating 256 takes 9 seconds on my computer so a whole sheet would take about 10 minutes! I will give it a go but its going to be slow. |

There is one problem with presets; every browser and every printer prints pages differently (especially the margins are different, and the DPI of the printer will also have an effect because CSS assumes a default DPI of 96).
It's better to give users enough control so they can try to find the right parameters with a few blank normal paper pages before printing on the sticker pages.
Mine uses PDFs so you just print it as actual size with the correct paper size and it will come out the same on every printer. |

I see, that's great. They do have templates on the website but not full specs. I guess I will order a few sheets to start with and measure and supply the required info.
Or just contact the company and ask for them? |

Mines coded in mm not inches. I cant find the specs for those labels on the website. Do you have the specs for them? I need these (in mm): Top Margin Left Margin Circle Diameter Horizontal Spacing Vertical Spacing Num Labels Across Num Labels Down |

I was going to code this anyway as i had the same idea! I tried using the print button in browser but the margins kept changing depending on the printer used. I have coded it in JSPDF (A Javascript PDF Creator) Which can be run in firefox or chrome (It works in firefox but takes forever, chrome it takes seconds). PDF With Text Private KeysPDF With QR CodesThe pdf generating code is done just got the GUI to do. |

If you order both, you will now get two notes with the same last 2 numbers in the serial. (see photo above)
