Do you think Tarkin can modify his code to boot with a later pi version? I would gladly pay to see this done, as I was the first to pay for custom work from him for the Titan miner project.

I agree. Debt is created to control people and enslave them for their life time and their children. Money is just created out of air, Governments are printing currencies out of thin air and they circulate it  among their citizens. It all just based of "TRUST". I recommend everyone reading this post to watch "Bitcoin the end of money as we know it". It is a wonderful documentary which will open your eyes.

Dear God No. This is me pounding my own head against the KNC wall. Besides I would rather blow up beaglebones on controllers trying to figure out some of these failures than the now limited supply of Raspberry Pi's.

Note: Everything I do here is my own work or is based on publicly accessible documents. I have no encumbrances or NDA's in this venture and I would prefer to keep it that way.

Update: I have the code working for a Neptune 100% on a beaglebone (yeah, big deal but it's a bitch to compile and get working) however Titan is still down. It's somewhere in the titan.c files in Bfgminer. But anyway in the meantime know that the newer version of fpga code on the Rpis can work with Neptune boards, so it's an enhancement to the Neptune code and not a replacement.

BBB's compile so much faster than Rpi's. I hate Rpi's.

Immediately stopped reading at compiling the miner with Ubunto.

Stop making coins that require all that compiling and building the miner bullshit. Not all of us are hardcore computer geeks with a shit ton of programming knowledge.

Windows exe file or not interested.


Good guide overall tho.

So if the efficiency is no better than a Titan -- then -- is this a SCAM?

Why would someone overpay to buy these units?  I'm lost here.

It seems that it is basically 2.5x as efficient as the 100Mh/s A2 units (which are selling for about $650 with PSU).

the fee of bitcoin transaction is very small. im not sure it's profitable.
if miner get profitable with "fee of bitcoin transaction" the seller and buyer will get loss in "higher fee" in bitcoin transaction 

Got to say from the specs on these units...gonna take a 'massive amount" to upend my Titan apple carts.......just saying....I suppose if enough of them work for a year and flood the market.

looks now like spec wise it is pretty much oranges vs oranges eff and mhs wise all in all

the main advantage with a Titan right now is if one of 5 cubes goes you still have 4 cubes (and hopefully lightfoot to fix the broke one) ..with the A4 if the board goes after

45 days you are skunked...(again unless lightfoot changes vendors)

Still,  if you believe in an eventual BTC pump to 800 bucks plus and LTC or scrypt coins to follow ..you could get one of these for a gamble ..but right how using this calc

www.lightcoinpool.org

I get a bit less than a year ROI at 12c kwh (winter 11c and summer 14c kwh ave) ...so the gamble is on a pump an mining paying off I guess

Then again an 800 buck BTC pump with LTC at 0006 btc to usd would be 4.80 usd LTC

one of these miners COULD climb out of that hole even with difficulty...but again if they flood the market even at the above rate would probably again reset to s year ROI anyway

Isnt this, in a way, expected? Not in the sense that Inno failed to meet some efficiency goals but in the idea that Litecoin (Scrypt) was to be ASIC resistant. Its true that ASICs have been designed for Scrypt (obviously) but they are not as efficient as those that were designed for SHA-256. Granted, a lot more money has been dumped into SHA-256 ASIC development compared to Scrypt but still. Maybe we are reaching the limits of what can be done with our current technology?

KNC hit a homerun with the Titan.

k previously I had -allcoins 1 .... trying -allcoins -1 now, seems it has started on devfee fine then switched to exp (my pool) and subsequently epoch... just fine as well ... will see what happens when next devfee pool switch comes along.
If this still fails, Ill have to get that -allcoins exp fix from ya.

I just tried to mine EXP, it mines it, after a few DAG switches it still works, no rejected/invalid shares. EXP has epoch #13 and ETH has epoch #79, so it takes in about 1.5 times longer to create DAG for ETH.
Try to specify "-allcoins -1" option, see readme for details. If it does not help, ask here if someone mines EXP and has same problems, this way we can confirm that the problem is not in your hardware.
PS. If you use dwarfpool (or any pool that accepts wallet address directly) you can avoid DAG re-creation at all, miner can mine EXP in devfee too. Though it seems "-allcoins exp" option was broken in v7.x, I fixed it and I can send you an update.

If you use same version and it started to generate DAG slowly - reboot PC, it's not miner issue, drivers or hardware failed. I have several rigs turned on right now and they work fine with latest 7.2 on Win10.
What version of the miner do you use? What pool do you use to mine EXP?
