BitCoins - who else on this ML is interested?

[AbH Belxjander Draconis Serechai]

I have managed to get a bitcoin and watching the IRC channel it looks good so far...

But I am wanting some help towards making a toolkit for AmigaOSv4 to use the embedded FPGA in my mainboard

Who follows bitcoins and cryptography?
  Maybe in part?

I might be able to grab some here and bring them along with me to Japan
for trading to ¥ since I've got a feeling my visa card is going to be
slightly useless once I leave the bigger cities.

You debit card can be used at any 7/11 or any Japanese Post Office.  Just make sure your bank knows before you leave that you are going to Japan otherwise they may tag it as fraud and not allow you to use it until you call them and remove the fraud alert.

Most small Japanese business are cash only establishments.  Event many of the chain restaurants don't take credit.  Expect to use mostly cash for eating out.  Hotels will take credit though.

I have interest in both bitcoins and cryptography.

I am currently taking the cryptography course at Udacity for fun (and learning the stuff in a more organized way as I didn't have the chance to take any cryptography related courses at the university).

I am also interested in FPGAs. There is an FPGA bitcoin miner that some people developed. That can help you start your project.

But I have to say that FPGA performance is pretty limited when you compare them with GPUs. For good performance, you must have one of the "high-end" boards. I tried mining some with the board I have, performance was very limited.

Did you see the NES miner?
About 20 seconds per attempt.

[Jud Taylor]

Nope. Where?  I am interested.  Thanks.

@Taylan:  Then we will have to organize meeting up so you can see the FPGA and 80pin header on my embedded PowerPC machine running AmigaOS

I have not written any BitCoin related code or re-installed Linux as a 2nd OS yet...

I don't have enough C++ skill to read the BitCoin-QT client yet...

I am more versed in programming on the AmigaOS using C and Assembly for 68K/PPC at this time

Trying to write a framework for executing Wine styled wrappers around non AmigaOS programs with optional interpretation or translation elements

@all  I would appreciate and constructive feedback as I have limited time to code but excessive planning time with a penchant for overthinking problems

See http://code.google.com/pop/polymorph for AmigaOS base code to make a shared library and tools

I would re-use parts of that towards a proof of concept AmigaOS client and embed mining into a library wrapping the FPGA usage as optional

[Taylan Ayken]

Definitely! I am usually at THS 2-3 times a week. The project I used had a Python script for mining: https://github.com/teknohog/Xilinx-Serial-Miner (Look under sources/software). It is easier to work with but if there is some code online that does the internet side of things, writing the serial port side is not that har.
The Verilog code can fit into a Spartan 3E 500K, I had a Spartan 3E 250K and it was too small for this application. The new Spartan 6 board I have can use the code. Size of the FPGA affects the speed.

I follow bitcoins daily and have invested in them heavily.  I am currently working with a friend to build a bot with python, whose api's will tie in to Mt. Gox and Capitolwords.com.  "What's that API? Congress is talking about bitcoins? SELL SELL SELL!"

This is uncharted territory, so if anyone has tied into an API before using eclipse, I could really use some advice.  

[AbH Belxjander Draconis Serechai]

@Taylan:  I need a hand updating python on AmigaOSv4 from 2.5.5 to having 2.7.4 & 3.3.0 then add a custom extension and use python modules to wrap C and the FPGA usage

@Garrett:  Do you want to join me and Taylan in making an expanded multi platform toolkit forWallets Mining and Trading based on existing projects?

[Jud Taylor]

Inneresding!

[AbH Belxjander Draconis Serechai]

@Garret:  Eclipse the IDE?

I don't know of many java based tools,  only the python and C/C++ tools being more common for now

My wife is a snow bunny too so the next time we go up your way... Ill try to meet you

@all Before I completely forget...

I'll be using a sam440 flex motherboard from http://ACube-Systems.biz/
PowerPC AMCC440EP processor and Lattice XP series FPGA on an ATX Flex standard motherboard
2x.Ethernet, 5x USB and 4x SATA ports with three PCI slots for expansion cards and an 80pin connector for custom Hardware

The OS supports an fpga.resource loadable.module as part of the AmigaOSv4 Kernel and the FPGA has support for a boot and runtime programs

Default boot is an IO program for fpga.resource syscalls to read/write to the 80pin connector with wiring documentation

I also have JTAG support onboard for the FPGA embedded along with header location for Lattice Semiconductor ispVM JTAG programming... but this needs a header soldered to the board for cable usage

Maybe custom wiring a breadboard and using the FPGA for writing to dedicated hardware on a breadboard would be better than reprogramming and soldering my computers mainboard?

[Garrett deRosset]

I would like to join you, but I don't know how useful I will be outside of javascript, jQuery, PHP, ruby, python, HTML, CSS.

@Garrett then you will be very useful for helping me setup a python scripted "server" to use from a browser to wrap the various functions required

That is the only truly independent GUI mechanism I know

Message me through the IRC channel and maybe we can talk more directly with this thread being the launch point for organising meeting online?

@Taylan can you join IRC at all as well?

[Garrett deRosset]

Ok, but where's the IRC channel?

Your prospects are looking like .0000001 bitcoin a day.  That's very close to being a selfless hacker.
