I received my 10 conis today! They are really nice. I little lighter in weight than I expected but very bright and shiny with a shimmering hologram sticker on the back. I can't wait to hand these out to friends. Thanks Serp!

Great!  Really glad you like them.

I would like to know if these are dependent upon a website outside of the BTC network.  If so, that would mean the site needs to be maintained online for these coins to work.  So they may not work 2 or 5 years from now.

They are not dependent on any website.  The QR code is a private key of a bitcoin address in WIF.  You can scan it in with a phone wallet app that supports it (the blockchain.info app for example) for easy import.  If you don't have one of those apps you can always scan in the QR code with any qr scanner and then copy/paste the text into any bitcoin wallet.

I'm really sorry btceic.  Not this time.

i would also like some shipped to eu if you have any left.

Send me a PM with specific location so I can make sure but it looks like it will cost me 0.145 + the cost of the coins (0.025/each) to send to that area.  I can send 10 or less coins this way I know but I could probably fit more coins in with this method.

I technically have 16 coins left still but I'm waiting to hear back from a few people.  I'm going to keep coin #1 for myself and if any others aren't sold by tonight I'll keep them to hand out locally.

Shipping within the US is < 0.05 in all cases I've priced out so far so less than the flat rate envelopes.  I'm using padded envelopes and each coin is in soft plastic.

Very nice. I am also working on a scratch-off version, but I think yours is better.

I suggest that you don't bother with a scratch-off sticker for the 0.01 BTC coins and reserve the scratch-off stickers for the 0.05 BTC or 0.1 BTC coins.

Yeah, I will possibly go to higher denominations in future versions.  With the effort and the loss from trial and error this first run is costing money for sure.  I put the scratch off on these because I really don't like the idea of just having the private code visible even on 0.01 BTC versions.  Once it's visible it's the same as redeemed to me.  But you are right, it hardly seems worth all the effort and cost.

I have been working on the link idea.
trying to put together a guide that explains:

1:bitcoin
2:checking balance
3:reedeming
4:spending

If you can help write the guide I could include your coins in the guide.
realbitcoin.info

Yeah, I picked up a few domains with that thought in mind as well.  I've just been so hesitant to flesh it out and put a URL on the coins though.  It's nice when the coins don't rely on any one website for anything.  I keep going back and forth on the idea but so far have settled with leaving a URL off.  A guide is a great idea and would be good for linking new users to it somehow but I imagine it would often be the case that some coins outlast the website.  As for including the coins in the guide, you should definitely put Casascius coins in there as he's the original and the basis for these coins too.

Great work on the site.  I would suggest you get into firstbits for the Checking Balance of coins since most the coins use that instead of a QR code.

I'm afraid I have to leave for a few hours.  I'm caught up on IRC but I have a couple more to answer on here.  I promise I will answer everything tomorrow.  There are currently about 16 coins left.  Cyrus I'll get you a quote.
170  Economy / Goods / Re: Aluminum Casascius Coins [loaded, qr code, scratch off?] on: June 22, 2013, 09:43:45 PM
BCB, I'll catch you in OTC.
171  Economy / Goods / Re: Aluminum Casascius Coins [loaded, qr code, scratch off?] on: June 22, 2013, 09:26:18 PM
I really want one! no international shipping   Sad

I am doing international shipping for someone else but after pricing it out it REALLY isn't going to be worth the shipping cost for just a couple.  But if you want send me a PM with location and I will price it out.
172  Economy / Goods / Re: Aluminum Casascius Coins [loaded, qr code, scratch off?] on: June 22, 2013, 09:24:26 PM
I'm interested in 4. How much would you charge for a first class envelope to somewhere in the United States?

I just priced out 4 for someone else and it is about 0.13 btc for coins+shipping.  Send me a PM with zipcode and I can price it out for you.
173  Economy / Goods / Re: Aluminum Casascius Coins [loaded, qr code, scratch off?] on: June 22, 2013, 07:58:29 PM
ill buy 10 if you will accept paypal, i spent all of my btc between terrahash and knc purchases.

Sorry Sad I would like to deal in bitcoins only for now.

There are 35 left.  Post in this thread or send me a PM.

So I've had a bag of these for a while now and have been working on scripts to create labels along with finding proper labels for them.  I have made 48 of them (1 sheet of labels) and loaded them with 0.01 bitcoins each.  I'm calling this first set version 0.1

v 0.1
 - weatherproof silver labels (laser printed)
 - full private key in a qr code
 - hologram scratch off covering private key
 - firstbits address on bottom
 - 10 mBTC at top
 - loaded with 0.01 BTC
 - sc v0.1 on left
 - numbered #/48 on right






Sorry for the picture quality.  I did them on my phone.

I used coin #2 as a test coin.  I scratched it off (as you can see above) and swept/tested the qr code with the blockchain.info app.  I wanted to use the mini key for the qr code but in my tests the blockchain.info wallet phone app would not read mini keys from a qr code (only the full private key).  Mt.gox's phone app was the only one to read the mini keys from a qr code I believe.  Anyways, the full private keys in a qr code seem to be fairly easily and reliably read from my phone at least.

I have 47 of the 48 coins left unredeemed.  I want to keep a few myself to hand out locally.  I would like to sell around 45 of them for 0.025 btc each plus actual shipping.  I'd prefer to ship within the US for now as I have no experience with the requirements otherwise.

Also, I'm really interested in ideas/suggestions for the next set.  I'd like to fit a link on there somehow which could teach someone more about bitcoins but not sure about it fitting.  I have some square hologram scratch offs on the way which would give a bit more room on the coin (and allow more room for error).  Any questions/thoughts?

175  Other / Beginners & Help / Re: Bitcoind CentOS Clean Compile On AWS EC2 on: June 21, 2013, 03:42:12 PM
A few things to watch if you are using the free tier is the number of I/O's you use on your EBS (you get 2 million/month free) and your bandwidth (you get 15 GB/month free).  I've not tried it but if you plan to run it continuously then you might want to keep an eye on these things.  I'd be interested in hearing how it goes.

Also, I understand if you want to stick with CentOS, but I wanted to mention it would probably be super easy if you wanted to just use one of their Ubuntu server images.  You could just install the O/S then type 'sudo apt-get install bitcoind' and probably be done.

They are pretty.

Do they look the same on both sides?

Ok with JS? Why not try http://brainwallet.org/#verify

It works offline and is pretty good.

If you look at the source you will see that the brainwallet you linked uses the bitcoinlib-js linked above.  Using the brainwallet software offline is fine if you are just doing one manually every now and then.  If you are wanting to incorporate the functionality into your own code then it is probably best to use the core library or just write your own.

We could also use a JavaScript library while everyone is at it. Smiley
