HASHRA - LUNAR SERIES - ASIC SCRYPT MINERS

[anarchoatheist]

Is there any way to turn the fan down on these? Can you please work on the decibel levels on the next version. It kinda sounds like a wind tunnel. I think maybe its the design of the heatsinc. The air passing over the fins creates some kind of resonance. I have been doing my mining at a friends house because he has free electricity. I brought this asic over and hooked it up and he said get that thing out of here. I need to find a way to dampen the noise, so I can get some free electricity.

I'm thinking to switch the fan to a much quieter but still high flow fan I have at home but no idea of the windflow of the stock fan. I wonder if you're right about the fins though, that would be a real pain as there's no way to get around that obviously.
Not sure about risking $2,000 on switching the fan tho...

I was thinking maybe putting one of these on each end. http://www.iaqsource.com/product.php?p=suncourt_dm106&product=111138&CA_6C15C=405309807. Or maybe rigging up my own with some acoustic egg crate foam.

you could build a 3 sides sound proof box - use thin balsa or 1/4 plywood and put some pillow foam on all three interior sides where the rear of the unit begins and have it extend about 8 to 12 inches behind the unit that will deaden the sound of the fan. as long as you don't interrupt the air intake or exhaust fan I think you'd probably be in good shape.

or open the unit up - gets some specs on the fan itself and see if you can find a less noisy fan.

that's a great idea! - the diameter matches the size of the fan also - I just measured my unit.

those dampeners are a little expensive. I'm thinking about making my own with some of this foam http://www.foambymail.com/EC1-5-F-CH/1-5-eggcrate-foam.html. This dampening technology should be implemented into mining machines, especially machines that are meant to be used by basic users. The big farmers get to go home and sleep away from these machines.
p.s. I also measured my unit earlier today. I havent measured my miner yet though.

mine are in my basement where it's 65 to 75 degrees year round so I don't hear a thing...

anyone get hit with taxes and what did hashra declare the value as ?

they declared mine with 326 USD and I didnt had to cough up any taxes. the big CE sticker helps for EU imports...

As a test I wrapped both ends with cardboard to see if it would reduce noise. It seemed to work a bit. Its about 15-20% quieter. I noticed though that a lot of noise comes out of both ends still (mostly exhaust). The sound waves are bouncing off of the cardboard back and forth then exiting. I'm gonna order some acoustic egg crate foam and put it on the inside of the cardboard tubes. This should succeed in breaking up the sound waves.

At clock speed 291, LL hashes about 12.8mh/s, 444 watts, still 6% HW errors.

Also, < 1% rejects on clevermining.

I switched from clevermining to http://coinking.io/?r=11339 I had over 2% rejects on clevermining and now I am down to 0.95 on
coinking.io - they also do poolmining and the poolside hashrate seems to improve maybe as a result of the lower reject rate? Anyhow I am happy with it and they have a referral program which compensates for the 1 percent pool fee they charge. Before I get flamed for shamelessly promoting this pool please try it our yourself and let all know if it works. I am not affiliated with them in anyway and yes if you use the link above I think I would get the referal bonus. Let me know what you guys think!

I finally got my y Lunar Lander today and it isn't working. I tried with a laptop (downloaded the software), and with the RaspPi that is included (which I had to power with another cable because it wouldn't join the internet - thanks to the thread for heads up on that); and on both *AS SOON* as CGminer starts, the unit shuts down. I get this error in the log on the Pi:

Icarus Detect: Test failed at /dev/ttyUSB0: get 00000000, should: 00038d26

Not feeling great about this.

My PSU is rated platinum and at 1300W - pretty sure that's not the problem. I have each plug isolated, so I don't think that is the problem.  Since the error is USB related, I tried swapping out the USB cable - no dice.

I am open to suggestions.

well - don't use their power cable to power the pi - myself and other have had problems. In addition the ethernet cable they supplied did not work. In addition make sure you're nit plugging in the additional 2 wire plug from the pcie cable.

send a message to support@hashra.com - their tech guy is very responsive.

Thanks - I did take the forum's advice and used a different power cable for the Pi, so thanks for that.  I am using my own ethernet cable, and I can browse to the Controla interface.  And no, I am not plugging in the +2 on the PCI-E connections.  The thing powers up fine... makes lots of noise and even some heat... but then instantly shuts down once I ask to to do some mining...

So working with Hashra support, it appears I have a defective unit.  Now it gets interesting.  While the support team was responsive and proactive, it will be interesting to see how this plays out.  Hopefully Hashra views this as an opportunity to demonstrate excellent customer service.  Stay tuned...

what kind of return are you getting in terms or btc/mh/day from clevermining?

Hello !

My ASIC arrived today but I have the same problem with the power cable for the Pi, like jjj0923 described.
Unfortunately I don't have any PI to spare, what shall I do ?

do you have any android phones like a samsung etc.

the power plug is the same.

additonally - there's a compiled windows version of the software on their website you can download and run cgminer for hashra from your pc.

I used the charger for my smartphone.
Right now when I use the HASHRA CONTROLA, I receive this message:
cgminer: Started cgminer 3.1.1
    cgminer: All devices disabled, cannot mine!
What is wrong ?

that's not uncommon - sometimes it takes a few minutes for things to start synching...

[coinwarrior]

are the fans turning and you connected the USB ports of the device(s) with the PI? if yes do a reboot on the console and see what happens?

[crocko]

I have a 750W PSU (CoolMaster G750M), and this should be enough for my LLW1.
My PSU seems to work, the PSU's fan is spinning, but the fan from the ASIC not.
I connected all cables, I don't understand why this is happen.
BTW, I connected only the last 2 PCI slots, If I use other combinations, the PSU don't work.

[coinwarrior]

you need to connect all 4 ports with the PCIE-6 pins and then use a paperclip or the switch from Hashra to "start" the psu. Usually there is a switch that Hashra delivers with the Miner that can be plugged into the PSUs respective port and can then be used to start the PSU but a clip will do as well... Give me a minute and I will send you more infos about the PSU "startup" process.

I did this before, but my PSU refuse to start.
Only in the combination described above, the PSU's fan it is spinning.
I need another PSU ?
And BTW, it is normal to have a red led on the Pi ?

[coinwarrior]

you bought the 14MH version?

If you have the 14Mhs version you need to attach the PSU to the TOP two power sockets. On the 14Mhs version the bottom power sockets are connected to nothing inside, that's why they won't work.
