Title: Demonstration of my Offline Paper Wallet Generator Post by: stevep on April 20, 2013, 11:48:17 AM Hi,
I've been working on an offline paper wallet generator for the last few weeks. http://www.youtube.com/watch?v=f7y_emuo68g (http://www.youtube.com/watch?v=f7y_emuo68g) What do you think? Source code is now available here. https://github.com/spearson78/paperwallet (https://github.com/spearson78/paperwallet) Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: marcus_of_augustus on April 20, 2013, 11:58:24 AM Neat.
Any long term 'big' plan ... or just a hobby hack? Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: stevep on April 20, 2013, 12:22:32 PM If there is enough interest I'd love to try and productize it.

I'm interested, especially if your device would allow users to adjust the formatting in order for the keys to be printed not just on regular paper, but on something like this: http://www.avery.com/avery/en_us/Products/Cards/Business-Cards/Two_Side-Printable-Ink-Jet-Clean-Edge-Business-Cards_08871.htm Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: cbeast on April 20, 2013, 12:48:20 PM Outstanding! This will be very useful for People that use Bitcoin ATMs and don't want to use smartphones. I'm a big fan of paper wallets and hope the development continues into deterministic wallets.

So what kind of printers would it work with .. something like one of those inexpensive portable printers? I think it probably has to be dedicated off-line (bitcoin only) printer for good security. A portable minimal printer and simple two button electronic box like you demonstrated would be a good package I think. And has the future expansion into a hardware wallet possibility also. Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: stevep on April 20, 2013, 02:33:03 PM My ultimate goal is a self contained unit that you can feed a blank note or a roll of blank notes into and press print.
I bought a couple of Epson M-190 printer mechanisms. http://www.epson.de/de/en/viewcon/corporatesite/products/mainunits/overview/9407 (http://www.epson.de/de/en/viewcon/corporatesite/products/mainunits/overview/9407) They're not much larger than the arduino and print using a ribbon Unfortunately I haven't been able to get the arduino to print via them yet I'm pretty new to electronics so I'm having trouble deciphering the data sheet. Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: cbeast on April 20, 2013, 02:47:27 PM Just a suggestion, but I am still hoping someone will create a program that will produce these (http://bitcointalk.org/index.php?topic=74978.msg831067#msg831067) from a deterministic wallet.

Your skills are pretty cool! Neat secure EMP safe DIY solution. Title: Re: Demonstration of my Offline Paper Wallet Generator Post by: stevep on April 21, 2013, 07:12:07 PM I published the source code here.
