Let's get this project Kickstarted (or equivalent)!  IMHO, projects like this are not only useful tools but are good for PR and helping a crypto-currency stand out against others.

At the moment I don't need funds to realize this Project, it will cost me less than 150€. So kickstarting is not needed at the moment. I also hate Kickstart Projects which takes forever and are delayed for months. Maybe we / I can kickstart it later to get funds for mass production but first I would like to have a working prototype!

I agree with you that this would be very good PR, this is one of the reasons I'm not using a simple yubikey which does almost the same. Also the NXT logo acts as the touch key to achieve brand awareness!

NXTBank would be interested in financing when the time comes. Feel free to submit a proposal here https://nxtforum.org/nxtbank/submit-your-loan-applications-to-nxtbank-!!!/

Best part is funds would be available immediately! Let me know if we can help.

Why don't you drop this in the AE - whereas one share equals the price of one unit? Then you match exactly what you need, and you know the demand pretty much instantly. Plus the buyers will get the goods - not like in kickstarter where it's basically a donation.
No risk involved except for shipping.

Btw- I'm so curious how this thing is supposed to look in the end. Do you have plans for some casing yet?
Shame there had to be chimps chips on that :D it looked so sexy in black and gold.

Edit: Chimps... lol, dear god.

So all someone would need to obtain the passphrase is a standard keylogger?
I dont like this.

Why not store the passkey on the device, send transaction details to it, after manual confirmation the device sings the transaction with the passkey and sends the
signed transaction back to the client, client can distribute the transaction.
If you want a device that you can use to spend NXT 100% secure, this is how its gonna work, the passphrase never has to leve the device.

If i store my passphrases in a encrypted file or device, and just copy & paste the key into my nxt client this would probably be safer than this thing.

Yes, this is absolutely required for it to function as 2 factor authentication.  The passphrase should never leave the device.

And you can do it with a 30$ Raspberry Pi and and an 5$ LCD Display.

However I do admit that the PCB looks pretty cool.

oh, a lot of posts. I have been busy IRL, sorry for the delayed answer.

Selling it over the AE could be a good idea. But as stated above, I can't handle warranty and UL / CE certification as a private person. I think we will find a way to distribute this device where I don't have to sell it by my self.

I don't have plans regarding the housing of this device. The touch interface (NXT logo) has to be left uncovered so you will see the bare black pcb and the golden nxt logo. I have access to a 3D printer and it should be possible to build a housing for my first prototypes. To be honest, this is my last priority :D

Please read the the last three pages of this thread. You can find the answers there. In short: This device was not meant to sign transactions in the first step. It could be possible with a software update but I simply don't want to promise this because I have no idea if it is going to work. Also you have to communicate with the client over USB and this is not easy with the javascript based client from wesley. So at first I'm going to build a yubikey style device which can handle different accounts and is supported by all clients without changes.

If you are afraid of key loggers please be warned that even simply key loggers are able to check your clipboard! So this is NOT safer than the NXTkey.

Regarding the price: Why would you spend 35$ for a raspberry pi and display? The assembled NXTkey PCB will cost something about 15$ to 20$. The Raspbpi is much bigger, more expensive, a pain in the ass to set up for a newbie and you have to wire it up with a touch interface and the display. So, not really a good solution.

Javascript based client should be able to save (manually) a transaction to USB device, which can be signed by the device that has that capability.

Good news first: It's alive! Bootloader, touch interface, USB HID Keyboard communication and the display are working!



The bad news: I'm running into stack / heap problems when the USB communication and the display driver are working at the same time. The lpc11u24 has only 8kB RAM which is not enough. I think I have to choose a bigger controller, something like the lpc11u68 with 32kB Ram and 128kB Flash. This means I have to make a new PCB :-/

Besides that, the actual PCB is working as expected and I can do software tests with each functionality on its own.

Do you think that I should make a second version of the PCB? Maybe I should file a bounty request and get some support from the community...

go for a bounty!

+1

Also agree in advance how things will work once you have got the working version done. I.e. when you come to sell them, possibly for profit  ;D will the bounty just be money for you as this is awesome, will be popular and you put a lot of work in  ;D or will you give x amount of money for each unit sold or repay the bounty as a loan later or ... etc etc

Clarity upfront, don't let things get messy later so neither party feels they got burned ;D ;D

please go ahead with this. :) do a crowd funding round on the AE. even if there is no promise of dividends im sure many many people would love to donate to help this happen, including myself.
