Hi, i have a problem with my moonlander 2. I have a Raspberry Pi3 and 2 Moonlander2 on a 20W powered hub. After a bit of work, one of the two moonlander go to 0 Mhz. Sometimes after 10minutes, sometimes after 48 hours of good work. I try to reset raspberry and change the hub with another one but the problem persists. I try to change the frequencies from 600 to 796 but the problem persists, i don't change any voltage. Do you have any advice? Thank you.  Try running each one alone at 600mhz. If they both run fine alone then the issue is with the hub. |

Hi jstefanop ,
Any update on this nice project?
Check the order thread, all order/shipping updates are there. |

Hey guys quick update for all Apollo Batch 1 Pre-orders. Final design is complete and we have all major components ordered/in production currently. ASICs are also in hand and PCB production should start next week.
Unfortunately we got screwed over with Trump China Tarriffs and had to switch out some non critical suppliers which is going to cause a 1-2 week delay from the original end of October start shipment date. We are probably looking first week of November to get the first orders out and all shipments should be done by Mid-Nov.

Obviously some components will have to be from China like asics they seem at the cutting edge with cheap manufacturing would make sense to keep the cost down. But if your gonna suffer from the raise in tariffs on stuff from China might be better possibly cheaper to have the shipped to Europe and forwarded to USA may be an indirect way but may be cheaper than the tariffs.
Yea we got the ASICs in so were set to at least start production on the PCB. Only bottleneck right now coming from china is the MCU and Fan. Even if we sent the shipments to Europe, they are still subject to a 17% import fee there regardless....trade sucks right now :/ Either way this at most adds 1-2 weeks delay, so worst case well start shipping beginning of november. |

hi all,
I have a question, I'm newbie and I have, I think a little problem with my ML2 usb stick when I plug (on my laptop, not usb hub) and start the
fan does not activate... and in the pool I lose mhs as time goes by. it's comes from power ?
THE FAN SHOULD SPIN-- Even in a USB 2.0 port, the fan should spin. Without it, the ASIC may become damaged. Is the fan plugged in to the micro-molex? Are the fan wires damaged? Is there a particle interfering with the fan blades? Check the close-up photos in the beginning of thread. --scryptr   the fan connector mounted correctly? Try unscrewing the fan and seeing if it spins when you plug it in...could be that it was tighten too much and was stuck. Either way if you ran it for a lengthy time without the fan running you have most likely damaged the ASIC beyond repair. |

i have one that is consistently slower than the other ones. i haven't adjusted anything, should i try for the core or memory? im running them at speed 796.  Definitely should tinker all of them. You have 35%-40% HW error rate !!! ( HW are hardware errors) ... your miners are actually working only 60 - 65% capacity) I'm keeping HW under 3%. EDIT: Read the OP. There is guide how to test them (using --benchmark flag). the hw rate on minera is calculated by accepted vs error. its not accurate. im running on a solo pool with very high worker diff.. so the accepted will be a low number compare to hwe in bfgminer log its only 1.5% [2018-09-27 19:24:18] 20s:34.65 avg:34.79 u:33.88 Mh/s | A:64840 R:230+0(.35%) HW:40689/1.5% ive tried speed 756 and 768 and it still is the same. Then it's ok. Suprised you can go that high. Might be some lucky batch. About the one miner try this: I was running Moonlander 2 for a couple of weeks, from internal USB of the laptop and had stable 4.7MHz/s speed at 832 freq.
Now, I got a good quality 2A USB hub. I put the core voltage slightly up and frequency 852. For a couple of hours it gave me speed of 4.9MHz/s and then stopped. I put the voltage back to previous position but now, no matter what frequency I put I get a speed of 3.1-2.4 MHz. Anybody knows how to check if I damaged the device? E.g. is there a way to check number of alive cores?
Thanks!
Put "-D 2>log.txt" at the end of the bat command. Start it up and it will spit out the log.txt file in same directory. In there you will see startup sequence and it checks for number of active cores. Should say 64. Yea I don't know why minera does not pull the HW error rate % directly from the miner instead of doing its own wrong calculation. I should probably update the driver to normalize the error shares based on the difficulty its mining (each HW error is hardwired to the internal ASIC difficulty which is very low). |

SORRY TO HEAR ABOUT YOUR MOONLANDER--
Did you do any adjustments to the Core voltage pot? I just got my MLD and have not touched the voltage pots. It does OK on 700Hz frequency on stock settings but hardware errors get big at 720Hz.
Just asking before I touch the pots. I am going steady at 3.9 MH/s at stock settings, 700Hz frequency. I am running a single stick on a USB 3.0 port of the PC, running Ubuntu 18.04.
Thanks for any help. --scryptr
P.S. Looks like a piece of Astroturf was pitched in the trash. Good riddance! (spam post was deleted). -scryptr
Never touched the pots. Just ran it as usual in a powered USB strip. I'm just super unlucky. Mine screamed like a banshee after a few weeks I couldn't stand it and removed the fan. Then added 2 external fans. It ran cooler that way and much more stable. Then it decided it was done hashing. Le sigh. Shoot me a message...I have had almost zero failures reported from all of these shipped, so I'm always curious on what fails on these over a really long time. Would be interested in getting yours to dissect. |

Hmm. Been running no issues for a long time and today as I walk away from my computer, bfgminer says moonlander2 stopped hashing trying to restart on loop. Shut down bfg checked the moonlander. Green light is still on. Weird. Restart bfg and says no device. K. Shut down bfg, unplug USB strip, unplug miner, give it a good blast of air, all clean , plug it all back in, restart bfg and blam no miner. So did it just die? Green light is on but nada. Thing doesn't even run hot as I have 2 fans on it and it's fall weather. Basically was mining all night and up until a about 30 minutes ago.
Windows do any updates? Make sure the moonlander shows up in the COM port...sometimes updates kill the UART driver and needs to be re-installed. |

Time line on first shipment?
First units wont start shipping out until end of October, and since these are getting manufactures in the states were running into issues with the new import taxes and trying to figure out how to minimize them. Some of our overseas components timeline could be impacted by it, but Ill have a better idea when units will start shipping by next week. |

Hello,
Power to the independent miners.
Ideally, the centralized mining cartel which is comprised of for-profit miners dumping into the markets can be overthrown.
The price point on these scrypt ASICs is just fine for any newcomer.
Can you tell us more about the platform's capabilities?
You mentioned a quad-core A7 ARM based controller.
What I would like to do is assemble a small swarm of them which report to a local P2Pool and coin daemon.
What's in the image for the controller currently?
Where are the sources for any modified miner which is required by them?
If some high quality work is contributed to help improve the platform software to give new buyers an easy way to join a P2Pool with their Apollo miners, would it be accepted upstream and be included in future images?
I'm looking for a way to do two things well.
1.) provide the common man an easy to use accessible miner which doesn't sound like a jet engine
2.) customize the control interface with retail branding and support options
Would love to hear your thoughts about the expectations new mom and pop miners may have with regards to support.
Best Regards,
-Chicago
Yes this is exactly what I intended to do with this platform. Probably wont make it into the initial image release, but eventual I want to give people the ability to run full nodes and connect to a p2pool for a true decentralized mining ecosystem. Definitely send me a PM if this is something your interested in, I'm looking for more software devs for the UI side of things. i was wondering about the same thing. i am hoping in your web interface we need the full address of the wallet or pool. ie http://192.165.0.2:3389stratum+tcp://bills.pool.com:3389 that would be super if its done that way. thanks most of the other manufactors get hung up on making you only put a strattum address nothing else. Miner still needs stratum responses though, as long as the pool/website is configured for the protocol should not matter what what the URL formatting is. |

Pre-order is now closed! Thanks for everyone that ordered, and for anyone waiting out for it to ship I should have a limited number of units shipping at end of October/beginning of November.

Are the 6 pin pcie sockets on the apollo standard size or mini?
They are standard GPU type pcie 12v connectors that come with ATX PSUs |

Already to rock and roll economically. Bring on October.
Just a note it say 12.4 on the readout presume its the volts will that be fine?
Yea regulator in the miner can handle a pretty wide 12v range. |

Ordered one and looking forward to play with this device!
Pre-Order is almost filled up and most likely ending after this weekend FYI. So last chance to pick one up at pre-order price! |

Thanks for the quick response guys. I'm searching ebay and amazon for the requisite power supply. I'm running into difficulty finding a 6 pin PCI-e.
I have until October though.
Yea 250 watts is just be being generous. Always add at least an 20% margin on top of the wattage you will be running at. So if your not planning to go past 100 watts on these and run them on eco mode, all you would need is a 120 watt PSU. The MAX you would eve need for one of these is ~240 watts if your running them at 200 watts. Problem is all good consumer power bricks usually only go to ~ 100 watts so I couldn't really bundle one of those with the miner which was my original plan for these to be complete plug in play. Anything in the 200 watt range are those shitty chinese aluminum screw PSUs, and then past that your in the ATX PSU territory. Im going to do some research and see if I can source a good ~250 watt for people just wanting to run one, otherwise if your running 2+ you might as well get a good 500 watt server or ATX PSU. Thanks, this will be helpful Apollo is ordered. Also hoping to get this https://www.ebay.co.uk/itm/HP-Switching-Power-Supply-750W-DPS-750AB-3-A-HSTNS-PD29-643955-101/153066774374?hash=item23a37d9f66:g:VDwAAOSwbzVbKBm4 plus a breakout board. Should be ok for upto 3 in future.? Yea server PSU + breakout board is always a safe bet...youll get really high efficiency and reliable PSU. That could run 3 as long as your not running them all full speed. |

yep appears to be a rip off, different circuit board design but most likely the same ASIC chip.... a certain country is very good at reverse engineering things.... LOL, reverse engineering? You think someone is that industrious? I could be wrong, but whomever jstefanop contracted out with to manufacture the ML2 either offered to remake these for this other person or the schematics were shared (possibly for a price) with another manufacturer. Could be an enterprising employee that has access to the schematics or even the owner him/herself. Electronics have a shelf life and the closer to obsolescence it reaches, the easier it is to have access to the schematics. Its all about the relationships and who you know in Hong Kong & mainland China. No one has my schematics/designs...the only possible source would be a PCB design leak from the Chinese PCB manufacturer I use. Even so they don't have the full BOM so they would still need to at the very least reverse engineer resistor values and guess on capacitors. On top of that they needed to pull off my UART controller code thats embedded onto the chip, since the stick can't work with my bfgminer code without it. You'd be surprised how industrious the chinese can be when they can copy a relatively successful design. |
