prospects for FPGA is indeed not so bright. If difficulty will grow near 18% in two weeks (it been growing around 15 % in 2 weeks recently) then by November 2013 diff will be  96203242 that means 0.08 btc per month from 500mgh FPGA unit.

Even for ASIC it will cut profit quite significantly, after last diff rise from 11 to 12 mills my bitcoin mining capacity reduced  from 10 to 8 btc per day  Sad

hope that btc rate will grow in same pace and bitcoin will not cost near 700usd by November. It may cost that much in fact, as we've seen with previous hash rate growth, btc rate been on rise too. In this case hoarding btc (or investing into ASICMINER shares) can be more profitable rather spending it on buying into FPGA mining.

Yep, thats 100% true, i think we'll have to wait for cheaper ASICs to come out and maybe then it'll make sense in making a all in 1 miner like this i guess, as FPGAs just wont do much in a few days

Cheaper ASIC will be on offer from September, many guys from Avalon's chips group buys may wish to sell.
I'm talking to few PCB manufacturers in Pune and HYD, but all usual staff, chances seems to be very slim to make it in India.

at that cost ROI is going to be in next ....... well  NEVER !

err, this is just a tentative spec, I am not selling it yet, I am looking for suggestions and feedback

basic idea is to make a ready2go miner, which does not need a host system to mine.

Was just considering this as an idea,

All in one miner,
RasberryPi as the host (with Cgminer or BFGminer)
4 x BlockEruptor USB miner

RaberryPi = Around Rs, 3000 = $53.66 = 0.413 BTC
4 x USB miner = 1.99 BTC each (if we buy direct from Friedcat) or else 2.1 BTC each (if we buy from another group buy)

Total would be around,

CASE 1 :
1.99 * 4 = 7.96 BTC
RasberryPi = 0.413 BTC
Total = 8.373 BTC

CASE 2 :
2.1 * 4 = 8.4 BTC
RasberryPi = 0.413 BTC
Total = 8.813 BTC

Would mine at around 380 Mhash/sec (?) * 4 = 1520 Mhash/sec or 1.5 Ghash

Power usage would be very very less though,
RasberryPi is powered by a microUSB (like the mobile ones)
2.5watt for the rPi + 2.5 watt*4 for the the USBminer = 12.5 watts

------------
This is a rough estimation, correct me if I am wrong Smiley

This +

It can be done easily, as setting up the rasberrypi won't take long, the only things that I have missed accounting for are,

1. USB Hub (Split 1 port -> 4 ports)
2. Power supply (ie, the same as a mobile phone charger)
3. Case (if needed)

These all together will account for a max of Rs, 1500 i think


Any suggestions ?

CASE 1 :
Total =8.373+0.21=8.583BTC

CASE 2 :
Total = 8.813+0.21=9.023BTC

At Max 70,000 INR for 1.5 GH/s

If it is Rs.1500, I am ready to purchase immediately.

Hmm, and what would you do with a USB Hub, Power supply and case?

It does sound like a good build if it can be done quickly.

that one looks like quite powerful FPGA
Problem is getting a  Raspberry at  market  rate price in india.

not a problem at all. buy amazon gift card for btc and they will send it to you in any numbers. Is it open source hardware or not, any one can check out.

hey thanks for the tip , now i will get my hands on my toy.

Alt coin FPGA will be very difficult to implement, I'm currently looking at a few boards for which the bitsteams are readily available and we can get them and quickly start to mine, rather than building the whole bitstreams agian

the only issue I see is that the FPGA is will give around 100 Mhash/sec max, probably will have to look at Spartan6 or other FPGAs

Hi guys,
I had recently been contacted by a member from here to start work on a FPGA* or an ASIC**, before I start any type of work on it, I'd like to know, if people would want something like this ? As I've started various things in the past and they have lead to nowhere, well no one to blame but myself because I did not do much research before starting it off, so this time I'd like to ask the community members before I start Smiley



* = FPGA would yeild about 100 Mhash/sec or so
** = ASIC would be using Avalon Chips


Thanks again!

Small update:
I have just received word that Benson is already working on the ASICs so, I have withdrawn the ASIC option Smiley I will continue to work on the FPGA as long as there is demand for that.

Not working on ASICS setup in India. That seems to be a bit out of my scope. Companies that i have contacted are asking for an upwards of US $ 950K upwards to get stuff in place to churn out some asics.

Trying to physically visit and verify upcoming ASICS companies like KNC Miner, but I must admit that this is a paid exercise from a client who wants to be on the first bus holding ASICS.

At the same time, it also allows for my trust circle to invest in KNC Miner if they prove to be good.

I am interested in your timelines for ASICS or FPGA. What is the capacity of production that you are aiming for?

FPGA now are best you can make it work for mining alt coins like Litecoin e.t.c  , I read some on this forum mining YAC coin using fpga , bitcoin mining using fpga is not a good idea unless you have some super duper fast mining fpga running @ Gh/s not Mh/s each.

I would be interested in buying fpga developed to mine any alt coin.

FPGA can be done right away, but it is around $350 which is the main issue I am seeing

ASIC will depend on when Avalon sends their chips, design will be the Klondike board as it does not make sense to redesign everything when there's a ready to go design available

I do not believe that your bottom line will be recovered from forum orders.

But any quantity at any practical price CAN be sold in India through several other marketing vectors.
