Demonstration of my Offline Paper Wallet Generator

Hi,

I've been working on an offline paper wallet generator for the last few weeks.

What do you think?

Source code is now available here.

Neat.

Any long term 'big' plan ... or just a hobby hack?

If there is enough interest I'd love to try and productize it.

Very cool!

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:

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.

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.

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.

[cbeast]

Just a suggestion, but I am still hoping someone will create a program that will produce these from a deterministic wallet.

Bitaddress.org works for me

Your skills are pretty cool! Neat secure EMP safe DIY solution.

I published the source code here.
