    Yes, I will get ordering parts soon. Been saving nicely recently, will be nice to get the garage widened. Also need a paint job.

    As for the mining code. My board connects to the internet, grabs the work information. Processes it in a number of seconds, throws away ones not in target, and sends off the valid ones. It appears to be doing the submit command correct. Perhaps my format is incorrect or perhaps my results are wrong, but I get no confirmation back. I will be using wireshark again to compare data packets from the PC and from my board. The results will be different, but should confirm the format and length.

    We have been saving too, but every penny is going to the new house and all the new furniture we are buying.
    Maybe 2019 will bring a Hellcat?!

    Maybe you will have a surprise in your new garage. You open the doors for the first time to find Clare has brought you a Hellcat.

    The FPGA miner is working. Finally got there, well happy and over the moon right now. My aim was to get it working first before optimising to make it faster.

    Now you would think and FPGA miner would be quick, this isn’t yet. The hashing is done in the FPGA fabric and completes in around 0.1 seconds, the sorting is done in C on a 700Mhz processor, this will be moved into state machines so my limitation is with the DDR interface. Next will be a wider connection to DDR 64 or 128bit with 2gb or 4gb of DDR ram, Ready for the BEAM or the 150,5. I’ll need to build hardware for the DDR ram, it will take it as an SODIMM form.

    Feels like i have created a child that is now finding its way in the world.

    So this board is using TCP-IP to connect to the server via the Statum protocol, signs in with a username and password, gets work, using the FPGA to hash this work, then the processor does the 9 levels or sorting and indexing then SHA256 and comparing with target before submitting the result. The result is now being accepted its been a long journey, 17 months i have been on this now. Next is to make this things faster a great project, and really happy its finally got to this point.

    So which part of the Otto cycle are you on when the #6 piston is coming up on the and the intake valve has just shut!!!!!!!!


    Just pulling your leg! Sounds complex but hopefully the results will be worth it?

    Its a great adventure. Feels like I'm achieving something, however it is taking up a lot of my time, taken me away from the forum.

    There is more for me to do on it. As although the 64Mb of data is created in the FPGA, the sorting is done on a CPU, so a lot slower. My next step is to do this n the FPGA too. At least I now know what every step needs to do, where before I was reverse engineering someone else's code.

    I have been documenting my findings along the way. It could be useful for someone else on the same journey. There are forums for the ZCash mining, but this is mainly people with GFX cards running software to produce the result. I have created hardware to do the same job.
