Hey everyone, update time!  So far, we've shipped over 30 Pipers and released the first software update which added some new features including Litecoin support and custom address prefixes.  We've added a lot more information to our site, including:
  • Interactive screenshots of the Piper User Interface
  • Full specifications
  • A feature list

We also have a fancy new domain alias http://piper.pw

Thanks everyone!


most thermal papers are impregnated with bisphenol-A, to the point of representing the main source of BPA found in human bodies

You'll be happy to find out that our paper is 100% BPA-free  Grin

First of all, kudos for the project that excels at so many levels. One detail that bothers me is the thermal printer technology,  for two reasons: (1) most thermal papers are impregnated with bisphenol-A, to the point of representing the main source of BPA found in human bodies, and (2) printouts are too fragile, cannot be laminated, and are sensitive to a wide variety of environmental factors.

You might be interested in my dot matrix based paper wallet printer.

It can print on normal paper and has the expected archival qualities of dot matrix print.

There is more to Bitcoin than bitcoins.

Hi everyone, everything for Piper ( https://piperwallet.com ) is coming along quite well and according to schedule.  

First, the good news

Today we received some new paper with a 10 year image life, and our test prints appear to be good so far.  To be specific, we now have rolls of appleton paper of grade 400-2.1.  You can see the different paper grades on this chart: http://www.appletonideas.com/Appleton/jsps/pdf/thermal/Storage%20and%20Shelf%20Life.pdf?0912

We are open to obtaining even higher grades with a longer image life, but we can't seem to find a source of it in the 2.25" wide x 50' long format or the 2.25" wide x 55' long format.  We've used our best google-fu but the best we can find is the 400-2.1 grade paper.  So if you can find a higher grade, we will buy it and ship it with Piper!  Please let us know if you find anything!  We'll give you free stuff in return Smiley

Second, the better news

Our enclosure manufacturer has just shipped our enclosure order, and according to the tracking number it's scheduled to arrive 5 days earlier than we had planned.  So you might just get your Piper a bit earlier than you expected Smiley  No guarantees though!

Third, we need your help!

We're finalizing the software and we need to know what you want Piper to include.  Piper is running on Debian (Raspbian specifically) Linux, so any Linux packages that you want, any Python libraries or development environments that you guys want, let me know.  

We currently have vanitygen and a local copy of bitaddress.org on Piper, and we're looking to add electrum as well.  The current Piper install uses about 2GB and we put 4GB SD cards in Piper, so we have 2GB free to use for more software.

Thank you everyone for your support so far!  I'm so excited to get Piper into your hands so you can start doing cool things with it.
