Storing bitcoins in a paper wallet is the most secure way to keep them, but making paper wallets is a hassle.  Piper makes it easy.

      Thanks for this. I have never been really big into Bitcoin, but with our business considering accepting bitcoin for our subscription services this will be really useful. I also have some plans to do some other nifty things with it. Receipt printer + PI = ideas.

      Absolutely I have the SD card, and that makes me feel much better. As far as the other currencies, you are correct, I flip fairly quickly, but there may be a time where, say, Litecoin takes off huge and would like to eventually like to have that option to store and speculate.
      Thanks for your response!

      Hmm that's a great question. Do you have an SD card reader for your computer? I will likely release an "official" SD card image, which you can download and then put onto the SD card with software like this (it's free): http://www.runtime.org/driveimage-xml.htm

      That way, if you ever break the software of your Piper somehow, you can just restore the image from the computer to the SD card, and it will be like brand new.

      Also, with regards to mining multiple currencies, I could be misunderstanding you (and I apologize if I am) but it seems like you don't need Piper to really deal with other cryptocurrencies. You say this: "I chase whatever's most profitable to convert to Bitcoin", so you're going to convert it to bitcoin in the end anyway, right? I guess my question would be "do you plan on storing other cryptocurrencies long term, or are you going to immediately convert to BTC?" Personally I would think you would do immediate conversion since the alt cryptocurrencies are very volatile, but I could certainly be missing something about your plans.

      Well, I chase whatever's most profitable to convert to Bitcoin, so there's not a single answer to that question. Today is Bottlecaps, tomorrow may be feathercoin. But you bring up a point on learning new things. WIll there be a "factory reset" in case I would screw something up? I can do hardware, but command prompts frighten me.

      Right now the software only generates bitcoin keypairs. However, I can include utilities for other cryptocurrencies as part of the software on Piper. That way, you could hook it up to a tv/monitor and a keyboard and mouse and generate keys for other cryptocurrencies.

      What other cryptocurrencies would you like to see?

      Also keep in mind that this is just a standard Debian Linux install, you will have full root privileges, and the software is all open source. So you could also add any cryptocurrencies that you want if you know how to use Linux, or if you're brave and like to learn new things.

      Is this Bitcoin only, or will this work for any cryptocurrency?

      Looking forward to using the Piper as a mining host (with a separate SD card) when I don't need a new paper wallet!

      I do think Piper could be a good tool for a beginner, and I fully agree that bitcoins can be unintuitive. Part of my goal when designing Piper was to make it really easy to use so that anybody, even new users, can keep their bitcoins just as safe as the "pros".

      I hadn't thought about a tutorial for new bitcoiners, but I think it's a great idea. I was planning to ship Piper with basic instructions on how to use it, but those were going to be for someone who already knows a lot about bitcoin. So maybe I'll create a web page to go with the instructions that have more in-depth explanations of what all the terms mean and stuff for new bitcoiners.

      Thanks for the great idea!

      Thank you for your response! Truth be told, I've been looking into bitcoins for a long time, and I love the concept, but I find the system behind them to be really unintuitive. Do you think the Piper could be a good tool for a beginner, and will you provide any sort of tutorial to introductory-level consumers?

      Just realized I didn't answer your second question, of what sort of performance is gained with the extra RAM.

      It really comes down to what you plan to do with Piper. The extra RAM will only be beneficial when you plug a keyboard, mouse, and monitor/TV into Piper and essentially use it as a computer. Specifically, the extra RAM would allow you to run more programs on Piper simultaneously. If your primary use case will be plugging a keyboard, mouse, and monitor/TV into Piper, then you will most likely notice a difference between Model A and Model B.

      This is a really great question and I'm going to add it to the FAQ right now.

      Piper is powered by a Raspberry Pi, and there are two models of Raspberry Pi, Model A and Model B. Model A has 256MB of RAM and Model B has 512MB of RAM. So therefore Piper Model A has 256MB of RAM and Piper Model B has 512MB of RAM.

      You can Google the Raspberry Pi to see it's other specs, and I may add them to the FAQ as well. I believe the CPU is a 700Mhz ARM SoC with a PowerVR GPU, but I could be remembering it wrong.

      Hey! This project looks really promising, but I have a couple of questions. The Piper B mentions that it has double the RAM of Piper A--how much RAM does Piper A have and what sort of performance is gained from the extra RAM?
