Are you certain that every cell of memory is used each time?
Even if not, how long do the 1024 32-bit words have to stay valid until the next call to scrypt() overwrites all of them? |

I'd just like to add that even if this thing can only put out as many Kh/s as a GPU, costs the price of a GPU, uses less wattage compared to a GPU, and will just run on its own while doing all that, it'd be well worth it for me and for many others (I'm sure).
This is obviously at the very least our aim, but anything better of course would be better. |

When doing 1 kilohash per second a completely new scrypt() is executed every 1ms, which overwrites all of the previous data. The maximum refresh period for most of DRAM chips is on the order of 64ms. For the homework solve the following problems: 1) how is the natural scrypt() refresh period affected by pipelining the implementation? 2) how is the natural scrypt() refresh period affected by reading the memory by a wider units than the 32-bit words native to scrypt()? If you solve the above without cheating you can upgrade yourself from "internet engineer".  |

Not just anyone can be an "Internet Engineer" you do first have to speak with authority.

I'd like to volunteer my services.  I'm an IRL electrical engineer. I also have all the tools I'd need to do hardware & software level debugging at home (scopes, power supplies, etc). I think their in-house guy is more than capable of doing such things, but I'm putting it out there just in case. |

"why smoothie isnt dead after drinking so much sugar, why simran is forever alone etc."  This made me LOL so hard. Also, I am very much looking forward to LTC fpgas, if not to mine with for myself, then for the increased security of the LTC network and less nuclear power plants running the LTC network. So excited  |

By the way, if you need a C/C++ developer for the project, PM me.

We completed our modules, and sent off for engineering samples, no we are not disclosing pricing/hashing info yet as we do not know what it will be by the time we go to production. There will most likely be at least 2 more redesigns when we have our samples. http://litecoinfpga.com |

A hint on the side of pricing would be helpful though - for people like me who do not have many bitcoins - and need to collect/buy them. A range is also fine. |

So how long will you mine before selling them?

0 days, 2 years. All in his right and of low relevance to you. |

Why wouldn't I keep a sample amount of the units we produce to mine? How could we know that the units work if we did not test them?

You should at least have some sort of newsletter sign-up on your website or something.
Very interested in how this turns out. May be interested in a unit or two if they are viable!
