Topic: 1BTC Bounty: mass-produced programmable USB stick w/ [O]LED display+button - page 2. (Read 5611 times)

Hi, I will send 1.0 BTC to whoever can point me to a device I can purchase retail (quantity 10-20pcs) with the properties described below.  In the event that multiple people post links to qualifying devices I reserve the right to pick the winner at my sole discretion.  The bounty will remain open for at least one week regardless of answers.  The bounty will close if not claimed in 30 days.  I have a history of posting bounties and making good on them (here and here).

I had my hopes up for Trezor, but it turns out that the Trezor developers community is targeting a market that doesn't include me.  That's unfortunate, but consumer electronics is a tough market so I don't blame them for being focused.

I'm looking for a device I can use for signing bitcoin transactions as well as for doing GPG signing and authenticating to my Kerberos infrastructure.  I am willing to write the software myself, and plan to release it under an open-source license, but it's definitely not going to be anything fancy or something your grandma can use, so don't get your hopes up.

Requirements:

  1. USB Male A-type connector (like a Yubikey).

  2. Ability to impersonate a USB HID device (i.e. keyboard, mouse) and a USB mass-storage device, preferably at the same time.

  3. Some sort of microprocessor/microcontroller on it that I can reprogram, preferably using an open-source toolchain.

  4. Nonvolatile storage for my keys.

  5. Some sort of display that can show at least 10x2 or 20x1 characters of text, preferably a whole lot more.

  6. At least one button on it, preferably two.

  7. Still being manufactured (so I can order more in the future).

  8. Less than $100 each, preferably more like $50 each.  I might go above $100 if things get desperate.

  9. Can be rendered permanently non-reprogrammable (fuse, etc).  If you're not sure about this one please post anyways.

  10. As small as possible.  Honestly it shouldn't be too much bigger than a Yubikey (but probably a lot thicker).

If I find something good I'll standardize on these as our security tokens too (hence the need for 10-20 of them and a reasonable probability of future supply).

Thanks!
