How are we suppose to pay at a shop on checkout without smartphones?

This is a good question! ;-)

Maybe with a smart card based system, but you have to trust the smart card terminal because you can't verify the transaction without a display on the smart card...

It's definitive hot wallet (for Proof of Love cryptocurrency). The blue one fucks red one.

It's cryptoporn !

It is a nice idea and the renderings are beautiful but I think he can't realize it into a working product. He want's to stuff wifi, gsm, gps, qr code camera and a solar panel in this tiny device. It is a nice design study but that's it.

Edit: This is one of the comments at his site:

"That is *some* feature list to get into a ridiculous thin package! Also, the mere fact you want seven people to work on this project for free, means you'll need luck. Lots and lots and lots of it!"

when does it come out?

Gr4ssh0pper · « **Reply #25 on:** April 29, 2014, 10:18:21 pm »

good question, I think I will have a working prototype in the mid of june. I ordered the PCBs today after finding two minor flaws in my design. This will take at least 10 days to deliver. More information about the timeline can be found in the initial post.

This is one juicy project! We are interested in embedding the key's transaction signing capability to the Offspring java client that already has advanced wallet features.

Gr4ssh0pper please contact me when you have a working prototype and if you would like to discuss the prospects of integration and possibly partnership regarding wider scale distribution.

Gr4ssh0pper · « **Reply #27 on:** April 30, 2014, 06:04:57 am »

Graviton, great to hear that you like my project. I will contact you when the basic functionality is working!

It might not be relevant right now but could you give an indication if you plan to sell shares on the AE? Whether on launch day or soon/months after? Trying to get AE launch info all in one place

That would be super

Thanks

I'm not planning to sell shares. I'm even not planning to sell this device by my own as stated above, sorry. But thanks for asking me!

Daedelus · « **Reply #30 on:** May 02, 2014, 08:44:34 am »

No problem, just canvassing everyone I know about just in case

I received the PCBs 5 days earlier than expected, I'm a little bit in trouble because I didn't order the parts for assembly until now $:-\$ I'm going to do this tomorrow.

Also after discussing with CfB and some other guys I found out that the passphrase can have UTF-8 encoded characters. This is a problem because a USB HID Keyboard can't send UTF-8 chars. I think that this device can only support passphrases with normal characters a-z A-Z 0-9 and special characters which can be found on a normal USB keyboard. At least this will work with the passphrases generated by wesleyhs client. This is only a problem for the yubikey style device which I'm implementing first. The signing device can store the 32 byte private key and doesn't have to deal with UTF-8 encoding. But.... I think there are going to be different, more complex problems with the implementation of the signing device (-;

Looks amazing, man.

Cool project.

You can send any special character using the "ALT+nnnn" sequence.

For example:
Ø (ALT+0216)
ß (ALT+0223)

Maybe this helps.

Nice project , I think we will post it in the news section of nxt.org site (when all will be done of course), wish you success with it.

I was thinking about this, but this is only working for Windows, Linux uses [ALT], [SHIFT] and [/u], OS x doesn't support it at all. :-/

Thanks but please wait until I have a working prototype.

I assembled two PCBs today and had some hard times get them running. After hours I figured out that I switched a resistor and a cap during assembly which prevented the USB bootloader to do its work. Didn't do some deeper electrical tests but at least the USB Bootloader is working now.

This project is important... Keep going I'm sure you will get help and funding...

BTW I tweeted you... and the initial reaction from one influential member was +ve as you can see below
