Could you upload some real photo of the device? I see some renders only..
Thx!

Hello guys,
I started a new thread to discuss current FPGA-miner-developers. Any feedback or comment is welcome!

This looks pretty weird because of these few points:
1. people are going the hard way: pci-e board, that needs advanced programming, drivers, etc. Development time is long for this single part.
2. pci-e board needs a complex pcb design, because it's high speed bus. This mining application has a requirement similar to rs232 or uart, or i1c, or spi, or whatever. Why to take a race car to deliver pica next door?
3. why 500 kh/s per asic? why not 333? or 666? or perhaps 777?
4. 20 watt per 500 kh/s is the power consumption of kintex 7 running open source ltc miner with external ddr3 memory. For the asic it should be in sub-watt range. Are you scamers using bitcoin asic data? There is huge difference between bitcoin and litecoin: bitcoin asic does processing every clock cycle a calculation in entire asic area. 
Litecoin asic makes a single access to the RAM every cycle. The RAM is 90% of the die, the rest 10% logic is not power hungry. The 500 khs/ asic would consume 2 watt using some old 300 nm technology.
5. LTDs in UK are well known in Germany as offshores and money laundering holes. That does not add extra weight. Might be just another company in Romania.

They maybe trying to split alg. Part in fpga/asic, part in host CPU.

That makes sense. The bandwidth needed to pass the PBKDF2 hashes in and out of the salsa engine is much greater than that needed just to send the getwork and return diff=1 hashes as it needs to be done per nonce (1024 bits per nonce, each way), so eg 500kHash/sec is 500Mbit/sec each way. It does seem overkill though as the PBKDF2 only takes up a tiny fraction of the fpga/asic.

I totally agree with you, I went this way in my attempts. But, think how simple salsa/RAM read/write is compared with PBKDF2 ..

True. I just coded a great glob of a FSM based on the original scrypt.c and fpgaminer's SHA256 core. Horrible way of doing it but it only took up around 4kLE (or maybe it was 8K, but thereabouts anyway) so once it was working I just left it alone as a black box.

If you go for an asic, you do it proper way - all inside single package. This split CPU/asic approach is just stupid. NRE, production cost and die cost is the same, but at the end one is asic, and the other one is only attempt-to-build-something. PCI-e bandwidth accessing RAM from peripheral is a joke, makes no sense even to start conversation about it.

01/11/2013 Update:

1. Completing the design and prototyping of our ASIC chips has been our priority thus far, we will showcase this in an ASIC prototype in the coming weeks. And as development has matured it has helped us to design a more powerful boxed solution rather than our originally planned PCI Cards. More chips can be packed per device and a fully built in solution which will give a lot more ease in connectivity to the miner. You can expect much cheaper cost per kilohash with this solution rather than a card design as well as performance per device being much higher than 5 megahashes or 10 megahashes. Final figures are to be announced soon.

2. New website will be live in the next 24-48 hours where you can sign up to the newsletter to get updates on our development.

3. Our partners have mentioned our partnership in an article by a major Indian newspaper 'The Hindu', viewed by millions daily. We will post up a link when it's out.
