I do not know why you would try to deny it - the miners are physically identical, the firmware still states 'PinIdea' in multiple places, and I am willing to bet the hashboards are physically identical. At the very least, you have acquired all the assets of PinIdea.

There is no doubt that DaYun is PinIdea now, they listed the Miner R1 for Cryptonight (classic) at same performance as the RR-210.

If they don't disclose the changes made to the algorithm, it may take a few extra weeks or months before new third-party ASICs show up. Reverse engineering a chip takes considerably longer than reverse engineering software. This is assuming that Obelisk actually has a secondary blake2b implementation on silicon, and aren't just making the change in software ...

I do not have access now to take a photo of the hasboard. a short movie below. https://imgur.com/a/hxetkZ7Do you know if there is a way to repair the hashboard? I have some skills ;-) @Mordred80 Z1. I think it flashes green, but I can be wrong :-) 7-zip (7-zip.org) can open/unpack the .img file Thanks for the video, better than nothing. The light pattern and physical build is identical to PinIdea RR-210, this just backs up my guess that DaYun is indeed PinIdea under a new name. I would try to log into the controller and stop the miner process, then attach to the serial interface of the failed board using `screen` or `cu`. You could additionally try to connect to the serial interface while the miner process is running, and see if it replies at all. The problem with debugging on PinIdea rigs is that they do not interface with the hashboards directly a la Antminers, but instead the controller communicates with a small CycloneV FPGA. So, due to a lack of debugging information from interfacing with this FPGA, the most I can suggest is comparing rails between working and non-working hashboards, and seeing if the chips are even coming online. For the image file, 7-zip FM is a good choice to analyze the image. Another useful tool is photorec/testdisk as well as binwalk, these can help you unpack old deleted files if they did not properly create the image. |

I have not seen it listed as 'Penta Miner', but it still makes sense if it supports 5 algorithms. Doesn't mean it's simultaneous. I don't know if it is simultaneous or not, I only asked a reseller about it and they told me it is one algorithm at a time. Again, waiting for somebody to purchase one and try it out =)

D3 is profitable again so we've listed it. Enjoy.
what the hell are you talking about? profitable again? Are you on drugs....give me some calcs or proof.. (me thinks you lie or are in major denial)  brad Prices were elevated about 24 hours ago, and even old Baikal sub-1GH/s miners were profitable for a few hours. It's over now, though. |

The hashrate report is correct, it is generating that number of hashes, but there is damage or other problems preventing valid shares.

This one supposedly does 5 algos at the same time.
I checked with vendors. The unit can only mine one algorithm simultaneously, which makes it much less useful. |

The board will not POST then. This is standard behavior of PinIdea board failure.
Can you please post pictures of the hashboard?

I doubt they can afford to fab chips for so many different algorithms right now. They also made the mistake of not decoupling the algorithms on their X11 chips - they can be used for X11 only, and not any algorithm built from the same components. Look at Baikal and now PinIdea/DaYun X11 miners - they are also capable of hashing algorithms using different combinations of the X11 algorithms. but if these are coming off their shelf from their active use; they aren't impacting the overall algo sum net hashrates as if they are a new product. You probably aren't considering this.
Their impact is minor considering the SPx36 units coming online, literally 31x the hashrate per unit. |

Interesting new miner from DaYun... specs are very weak, seems to be maybe an old model from their days as PinIdea that they just want to get rid of? | Groestl | 2.6 GH/s | 200 W | | Myr-Groestl | 4.3 GH/s | 220 W | | LBRY | 1.536 GH/s | 11 W | | Pascal | 2.3 GH/s | 3 W | | LYRA2rev2 | 192 MH/s | 25W |
Interesting to see how low the draw for LBRY and Pascal are.. perhaps this machine was a testbed for each of the chips they made? Or perhaps to keep the hashrate per device low enough that nobody suspected them secretly mining. If anybody gets their hands on one of these, I would love to check the firmware image to see how long they have been using them. When PinIdea launched the RR-200 I was able to confirm they had chips in hand and mining Cryptonight as early as August 2017, long before anybody started pointing fingers at secret ASICs. |

Monoro sounds like an interesting project  |

There is a modification you can get for 25 mBTC, to make the miner connect and hash on CNv2 pools. I think it is being offered to buyers with more than a few machines only, though.

What the hell is your problem? |

The duct works pretty well |
|
|

It worked for CN-lite before coins using CN-lite changed to a newer version that isn't compatible with these ASICs. Anyway, if you really want some firmware to mine CNv2 with these units, you can get it for much less than 0.18 BTC  |

Usually stores listed on asicminervalue are OK.
