Looking for TI Calculator ASSEMBLY Programmer to make Wallet Generator

[str4wm4n]

I was intrigued after reading this thread
https://bitcointalk.org/index.php?topic=286534.0

And I desire a program written to work on the TI-83+ graphing calculator that is able to:

1. Generate bitcoin wallet private key using user imputed entropy ( rolling dice or something )

2. Generate a private key and hash it into a valid bitcoin address

3. Display the address as a QR code

I assume since it's on this board, you are willing to pay.  Did you forget to say how much, or maybe you are looking for bids?

I am interested and have a TI-84+ (seems to be backwards-compatible with 83+), but realistically would probably only get around to it if there's some money to be earned (or at least several people who would appreciate it ).  I'd prefer to release it as open-source.  I'd need to look at the specifications closer and do some estimating on whether it can fit in the space requirements and won't be painfully slow, before I devote too much time.  I also wonder if a bitcoin QR code can be reliably scanned from that low of a resolution.

I am willing to pay. What would you charge for doing such a project?

How about 1.5 BTC?

This sounds awesome I'm just putting that out there

I've got some barebones C code that generates privkey+address and works on Linux.  I was working on compiling it for the TI with the sdcc compiler.  I may also have to rewrite the input/output to use the calculator's system calls.  There could still be pretty big obstacles as far as what the compiler supports and device constraints.  I haven't had time to work on it in the last week.

To be honest I will probably do it without a bounty, but would like one and can justify working more if there is one.

Sorry to bump this thread without delivering.   I just wanted to post a link to my unfinished code: https://github.com/scintill/ti8x-bitcoin .  I may take it up later, but for now I've hit a pretty big obstacle with the size of the compiled code being too large to put in an app for the calculator.

It may be useful to port to other small systems.  It probably ought to be licensed under GNU Affero GPL due to linking with MIRACL.  I haven't officially put in a license yet, as I am not sure what I have the rights to do with rmd160.c, which is derived from the reference implementation of RIPEMD-160.  I'll try to clear that up soon.

What about an HP 50g calculator?

I would buy a TI if it meant I could generate wallets with it I'm just putting that out there
