Paypals fee is 3%....where did the other 7% come from??

You received and answered pms but in this thread people have made multiple offers and u have yet to even reply to a single one with a counter offer. If u arent because udk what to sell them for then really u shouldnt be listing them for sale. Its one thing u say OBO and wait for offers....thats legit...but getting offers and not countering or accepting the offers being given isnt a good way to go about this.

Just my opinion. I was gonna make an offer but after watching this thread and how no one gets a counter there really was no point in it.

I will buy the kit from u if its still available. Im in the us....maryland to be more specific so if u want to sell it i can pay with paypal because im not using btc for purchases right now.

Like the title says im lookin to buy antminer c1's with or without the cooling kit but i prefer the kit be included to save me time setting up my radiators. If u dont have either but have the syscooling sc-c2 monster cooling kit i will be interested in buying that as well.

Keep prices legit please. Im in the US so dont expect me to pay hundreds in shipping because ups and dhl arent needed here....usps with insurance is just fine for shipping within the US.

lol uk i replied back to u a while ago but u have yet to send the invoice.....u coulda said nvm....

dang your prices are high! ebay has them for anywhere from 400-625 fully working and thats completed listings not the ones where being are asking $1800 for one miner but wont ever get that much....i only looked at the ones that sold. I buy broken miners or half running ones for much less as well. if you want to get a sale here you might want to lower your prices unless you find someone willing to spend that much but i doubt it.

is http://cryptomining.farm not working for other people?? it loads but the stats dont show up on any of my browsers and the miners dont do ne thing when they run.....

Ok so to join a pool i need 1 burstcoin and i went to one of the faucets to get some coins to join one of the pools listed but it gives me the error:

There was an error processing the request. Please ensure the address entered is correct.

I have tried solo mining with about 3 1/2tb but that wont get me far im sure but even then idk if that will work as my address since it isnt seen as a valid address. i saw others mention this but after getting sent some coins it activated the account so can someone send a few my way to get my acct activated??

 BURST-6LC2-X8T4-AWLT-CWJ63

thats what my wallet says my address is and its fully updated and downloaded the whole chain already but i have 0 coins.

on a side note how do i change the plot size in the plot maker app?? When i use anything higher then 1000 it just closes. I KNOW FOR A FACT I HAVE ENOUGH RESOURCES. This is on a dell t610 with 48gb of ram and 2 8 core procs and 3 1/2 tb of hdd space. 2 hdd's are 1tb drives and it ran all weekend and hasnt even finished half of the plot making on them....its ridiculously slow. here is my batch file config:

C:\Windows\SysWOW64\java -Xmx1000m -cp pocminer.jar;lib/*;lib/akka/*;lib/jetty/* pocminer.POCMiner generate xxxxacctidremovedbutiinsertitherexxxx 0 400000 1000 2

any ideas?? if i change -xmx100m to 2000m or 3000m or anything higher it will not run. If i change the number at the end from 1000 to 2000 or 3000 or 4000 or anything else it yet again will not run. If i change both numbers to the same number at the same time it will not run. It will only run at the numbers shown and maybe lower idk because i dont want to go lower i want to make the sizes larger. thanks in advance.

So does anyone have the v0.8.0 yoli board firmware and or bootloader update?? I cant update the firmware without updating the bootloader but i cant use the hashfast app with linux to install it even after fixing the issues with pyusb and python.....i have spent days trying to build everything and im getting annoyed at the fact that their instructions leave so much information out and that they could have easily posted the hex files already made for the update alongside the non compiled files but they didnt....it makes no damn sense to me!

the guy i purchased my boards from said he thinks hf posted a firmware update for the boards but has since removed it and i cant find it anywhere....does ne one happen to have the update still?? can u send it my way in a pm??

also to people running their cards outside of the cases....are you looking to sell your hf case?? if so i might be interested in purchasing one or 2 if the price is right. i might even want some of those wooden ones or the plans to make them so i can do it myself if its too pricey to have them pre made. pm me if interested.

i have returned to offer some help to peeps or at the very least provide some more interesting info i found out.

1. like the post above states there are 3 colors used. red, green, and an amberish color. The red usually shows up on the far far end of the string of lights and the others are greed and or amber. I got a coupleof boards in the other day that i paid $53 each plus shipping and one had green lights with a red led at the far end and the other had all amber lights with a red one at the very end. Im assuming this was one from a batch that substitued the green lights for amber ones since it makes no difference what the color is and it doesnt seem to indicate any issues. Now some may notice lights are off in the row of diodes and that means thats a core that isnt being contacted or is shut off to protect the core from damaging voltages. i have no clue which belongs to which and dont care to be honest.

2. these dont need the waterblocks on them to test the power. sounds stupid i know but if you connect the power to them with nothing else connected the lights will come on but the dies on each core will stay ice cold. some may be wondering whats up but after i played around  and pulled a dummy move of not connecting the pump cables up i realized the lights dont cycle when the 3 pin fan connector has nothing attached and or the fan runs slower then a certain rpm. If you look in the status page of a terra miner it says the fan speed of the fans and the fan speed of the pumps which the pumps dont have fans but they do communicate like they do so if a pump is no longer able to hit lets say 2000 rpm but the miner is set (cant change this normally unless modding cointerras firmware) to only kick in the core when the 3 pin fan connector detects 2000+rpm then the board shuts off that core and will not start it even if the second pump is running fine and circulating the liquid over both cores. soooooo with that being said this also means something else can be used to cool the cores instead of expensive water cooling kits and that something is air . if you get a higher end heatsink sure it will be louder but you will no longer have to worry about leaks and or a pump dying. if a fan dies the core shuts off and you replace that fan with an equal or better cfm fan that is controlled using 3 wires and your all set. itried out a coolermaster heatsink with 3 moddel dell delta fans  with 2 pwm controllers specifically made for 4 pin fans and it was able to cool the cores down when using diamond thermal paste. i got the temps to drop to about 70 degrees in a room that was pretty warm because i closed the door to work on everything in peace.

3. if your psu is going orange on you get a standard pc psu and remove the board from the miner. cut the wires or in my case make a new pci-e connector with just bare wires on the other end and hook them to the terminals. it would be best to get 3 wires of pos and 3 of ground hooked to ring terminals but if you dont have a home depot or whatever near you you can wing it but ring terminals are the best way to go and they will securely lock the wires down. anyway after having 3 of each hooked to the correct power posts and having the board sitting on a piece of cardhoard or in my case supported on some m3 spacer posts power on the psu. Once you do one of the mosfets will probably burn up. i have had at least one burn up on every board i connected to external power. its never the same one and i believe its because thats the weak mosfet causing the spu to sense a problem and shut off to pretect the board. I repeat one mosfet has burned up on every single board i have repaired. once the mosfet is replaced doing the same thing again doesnt cause it to burn up. this tells me the psu sensed a problem and shut off before the mosfet blew which in this case you want it to blow so it puts a mark on the top of it allowing you to find the damaged mosfet. with the psu turning off before it blows it allows it to stay in tact making it hard to find the damn thing. also once blown it wont allow the psu of the miner to communicate with that die so it wont sense a power problem and usually allows the miner to start up without however many mosfets that blew. it sounds bad but really its fine. just provide power and wait a couple of seconds and check the top and bottom for the blown fet. cant get anymore simple then that really. so a standard pc psu has 2 roles here….one the power pushed into the board lets you find the bad mosfet and 2 the psu provides the unmetered power to the board and wont shut down like the main miners psus would to prevent what your trying to have happen. idk about u but i rather have 1 dead die and 7 working dies to mine with then 8 dead dies and a board that shuts off to protect the fet that is gonna blow anyway. that and u can replace the fet allowing the board to potentially hash at full tilt again .


i will keep posting more info when i run into those issues. u can take it or leave it but i will still post it lol. Also i will offer my help replacing stuff on the boards if people want. I will only need the board nothing else and if i replace the mosfets its $100 flat for the first one and $10 per additional fet because it takes a long time to heat these boards up to temps that allow the solder under it to melt so the $100 covers the first fet and the $10 each covers each additional one. if i cant make any progress with the board then u only pay shipping to and from me. so $100 plus shipping to and from me or shipping to and from me. Or you can run it the way it is if you want lol idc just throwin that option out there. Or you can sell me ur miners or parts for them too like psus and psu boards and water cooling kits and so on.

finally since everyone i see on this forum posts donation addied i thought y the hell not?? if my info helped you in ne way and ur feeling greatful lmk by sending some btc my way its wayyyy cheaper then cointerras help thats for sure!!!

damn…..ne burned up components or char marks?? when hooked to a psu does the light turn amber and when unhooked from a psu the light stays green?? i keep popping into this thread so i will keep an eye out for replies. i just got one board workin this morning with an ultrasonic cleaner and a tank of CLR (yes the calcium lime rust cleaner) and distilled water cause the dummy thought alchohol was the best way to clean the beard which it isnt lol. so many do that and im not sure why but their loss is my gain i suppose.

well do the lights on the card come on and cycle through the green leds before starting all over again?? if so check the usb hub cointerra used in the machine and read my post above yours. its ballz long but it can help prevent the melting with the psu boards.

as for the psu screw size….its the same size as the ones on the cover they put on the side of the miners case. you just have to remove the screws and pop the tabs on the sides to lift the cover off. when they are facing the right way and have the fan mounted to that hole on the side of the case then the back cover that goes over the psu's can be removed because they will be blowing air instead of sucking in air so the air coming from the radiators wont effect the cooling performance which i assume is y they put that cover over them to begin with.

ok so because i believe in sharing info with others especially with mining hardware makers that take little to no time to help users out after they fork out thousands and thousands of dollars i have decided to post some info here for the community and hope it helps some people out.

brief back story:

i purchased a terraminer from a seller on ebay that ran at only 700gh/s for about $500 and paid in btc. the seller was an awesome dude and got that beast sent out and packed very well. he showed pics of the miner both inside and out and there were no char marks on the boards. the psus were green so no board shorts in this miners case but i m working on boards that have those issues and will post that info as well if i get some extra free time when im finished fixing them.

problem #1 - the first thing to check when only one board is detected is the little black usb dual port hub they used in these machines. Now i have never ever seen this issue in all the years i have been doing pc/laptop component repairs so this kinda shocked me but when i was swapping the usb cables from one board to the next i noticed only one cable was able to talk to the beaglebone at a time. i assumed it was a cable defect even though there were no signs of cable damage. since these miners r hard to move around in even with all the extra room (weird....i know but if you have to hook and unhook the power cables to the boards as many times as i have your fingers get very very sore) i didnt remove the hub which i should have because it would have saved me troubleshooting time. one of the pins on the bottom usb slot was completely burned away. im not sure y this happened since i thought these got power from the psu and not from the usb hub but after taking it out and removing the housing cover from the actual usb board i saw the white electronic smoke marks on the corner of the case in the same place the burned up pin is located. now when i say burned up pin i mean gone....not charred or singed i mean there was a pin there but now there is no pin there at all so swapping the usb hub out was a pain because i had to unhook everything again but once i changed it both boards were detected. on to problem #2!

Problem #2 - the miner was detecting both boards and hashed away at much lower speeds then i had hoped on the second board so i pulled it out and saw the tell tail raised dots on a few mosfets. I immediately said awwwwww shitttttttt cause the codes printed on the top of chips doesnt always lead you to the component you need and cointerra wasnt gonna tell me shizz as usual so i gave the code a quick search and sure enough the one printed wasnt the full product number but luckily there was only one item with this number so the extra part of the code that was left off of the chip doesnt matter because that product family only has one version in it so no worries about getting one that is too low a spec or even too high. luckily digikey (awesome company) has these bad boys in stock and ready to go so i picked up some of them. here is the link:

http://www.digikey.com/product-detail/en/CSD16342Q5A/296-30314-2-ND/3074512

i had to pull out the bad ass ir station to replace them because these boards just suck the heat out of one spot so the smaller machine wouldnt get to the melting point of the solder no matter how long i waited but after swapping those out the board was running at 700gh/s just like the other one. now ik some are saying "but they should run at 800gh/s" but i paid $500 and resolved the issue and now get over 80% of the power out of both boards so beggers cant be choosers and risking damage from heating and cooling the boards to replace other chips wasnt worth another 100gh/s or risking losing more gh/s by mistakes on my part....im only human and like eveyone else i make mistakes so it wasnt worth it to me. 1.4th/s vs 1.6th/s was more then fine given the price i paid.


Problem #3 - the psu's ran pretty hot. this annoyed me even though they run fine. to resolve this i did a couple of things. first i opened the psu's up to see which was the fan was facing. i found out my psu's sucked air in from the back instead of blowing air out of the back which i would have expected it to do. so to get to step 2 i had to swap the airflow 180 degrees. to do this i remove the fan and pushed the 4 rubber holders through the mounting holes so it could be taken off of the plastic mounting plate (sounds confusing but if you look at it you will see what im talking about). once removed i flipped the fan around making sure to keep the fan cable facing the same way and pulled the rubber mounting legs through the fan holes to lock it back to the plastic mounting plate. the fan sticker has to face the back of the PSU (back being the area the power plug connects to). Once i test to make sure it works i put it back together and made sure they could power the mining boards and that nothing bad happened lol. **NOTE** im not responsible for ignorance. If you cant do this or havent opened things like psu's or computers before then proceed at your own risk and you risk being hurt big time from the caps in PSU's so please be smart.....pay attention to what you touch and dont rush things. On to #4!

Problem #4 - now that the psu fans are in the right direction i thought maybe i want huge airflow blowing into them to keep them ice cold soooooo thats what i did. I have some old delta fans that were installed in podiums to keep air flowing into the area where PC's were installed at a campus. these plug into the wall and run on 110v power so no special wiring needed and they move alot of air through their blades and dont sound like delta computer fans that resemble the noises plains make when taking off. they arent silent but they dont compare to the fans in the front and back of the miner already so ya it wont add any noise to your setup. i put the fan on the side after drilling a few holes because the fan is a little smaller so the original holes dont line up....they come close but if i had another inch i could have used them but i didnt so i just drilled some fresh ones no problem. the fan blows air into the hole which is why the psu fans needed to be set to blow air out of them and now into the same place the delta fan is blowing air because the delta fan will win killing the internal psu fan because of the pressure created. some may not care about psu temp but when i took the psus out after running an hour long test they were hot to the touch for a long time after they were in use which will slowly kill the machine. a cold machine is a happy machine. even though i paid little for the miner i didnt want to run it until it died.....i work on olectronics for a living....ik if you treat things right and take care of your stuff they will pay you back in the long run. and its always better to prevent issues then it is to scramble around waiting for stuff to come to resolve the problems your having.

problem #5 - the power cables. this goes without saying im sure but what the fuck was cointerra thinking when they decided to use utility power cables to power these miners?? they put extreme amounts of preasure on the terminal ports on bother the psu and the miner boards. i had one board that had the connector ripped off. sure they may be sturdy when mounted on the boards but the power cables have no give in them what so ever and will not sit perfectly and after tearing my fingers up trying to get them on and off the boards to test i finally said "fuck it" and went back to my car audio installation days and grabbed some 0 guage amp wire. this shit can handle 250a or 3500w per cable and thats for the entire length of a car which isnt whats needed here so if it can provide stable power to 2x jl audio 1000.1 amps which are powering 2x jl audio w7 13.5 subs then this can surely handle some wimpy miners and sure nuff (ik its enough) i was right lol. not only can it handle more then the entire miner puts out but its extremely soft and flexible unlike the cointerra psu cables. they will need to be zippe tied to keep them out of the way of the fan or laid down along the bottom of the case or whatever you choose to do but no matter the choice one thing is clear....im glad i "voided" my warranty by making these changes. I no longer have to wonder if my psus are gonna die from running hot or if i will rip off a post from the board. if they die i know it wasnt from heat or non flex power cables!


sorry guys for makin u read my essay. i try being as detailed as i can when explaining things like this and i hope it all makes sense but most of all i hope it helps someone out with a miner they are having issues with. just know if both of your hashing bards have the lights cycling through the bottom of the board it could be something as simple as a burned up usb hub port and most wouldnt think to look there....i know i sure as hell didnt but im glad i did even though i feel silly for not doin it before lol.

p.s. DO NOT FLIP THE POWER CABLES ON YOUR MINER UNLESS YOU FLIP THEM ON THE PSU TO MATCH WHAT YOU DID ON THE BOARDS. POS SHOULD NEVER BE HOOKED TO NEG. THATS JUST COMMON SENSE. EVEN IF YOUR DESPERATE DONT DO IT GUYS! I CANT BELIEVE SOME HAVE TRIED BUT I HOPE THIS STOPS OTHERS FROM ATTEMPTING IT. NOT EVERY MINER USES THE RED CABLE FOR POS AND BLACK FOR NEG BUT IF YOU PAY ATTENTION YOU WILL SEE EVEN THOUGH THE CABLE COLORS ARE NOT THE SAME THE WAY THEY ARE HOOKED UP IS. FOR EXAMPLE IF YOU HAVE A MINER THAT HAS THE RED CABLE ON THE NEG TERMINAL LOOK AT THE PSU....YOU WILL SEE THE RED CABLE IS ON THE NEG TERMINAL OF THE PSU TOO. THE COLOR DOESNT MEAN IS POS OR NEG....ITS HOW ITS HOOKED UP TO THE SYSTEM. I COULD HAVE USED YELLOW FOR NEG IS I WANTED TO. IT WOULD CONFUSE OTHERS AND I AGREE THEY SHOULD HAVE FOLLOWED THE TYPICAL COLOR USAGE PATTERNS THAT ARE A STANDARD THROUGHOUT THE ENTIRE WORLD PRETTY MUCH BUT THEY DIDNT. MAYBE THEY DID IT TO CATCH MINERS OFF GUARD SO THEY FRY THEIR BOARDS CAUSING MANY TO PAY $350 JUST TO HAVE THEIR BOARDS LOOKED AT....I DONT KNOW....WHAT I DO KNOW IS IF YOU SWITCH THE POLARITY YOUR GONNA SCREW YOUR SHIT UP AND PEOPLE TELLING YOU OTHERWISE SHOULD BE IGNORED.....EVEN IF THEY ARE RIGHT IGNORE THEM.....IK I WOULD NEVER TEST THEIR THEORIES OUT EVEN IF IT WAS PROVEN TO BE TRUE BECAUSE IT GOES AGAINST EVERYTHING I HAVE LEARNED OVER THE YEARS ABOUT THIS SHIZZ. ITS OK TO BE A JEW AND NOT SPEND MONEY TO HAVE SOMETHING LOOKED AT BUT THERES NO EXCUSE FOR STUPIDITY SO YOU HAVE BEEN WARNED.

ok so i was arguin with BA back and forth for a while now and mostly getting no replies or replies that were late but a couple of days ago i finally got things movin in the right direction.

https://github.com/blackarrowsoftware/

the link above has the controller board files if you want to give them a quick download and check them out. this will help people like me make these boards and repair them without having to figure out what each component rating is and so on blahh blahh but ya hopefully others can benefit from these files. idk what app opens this format but i also havent tried finding out yet because im busy repairin cointerra miners but i saw the email on my phone and wanted to post the info so others know too. the files were justtttt uploaded so they are fresh fresh fresh. enjoy .

how much and do u accept paypal??

1. Sooooooo i had a few questions about these miners…..i finally got them workin a while ago but when lookin online for controllers i saw  where blackarrow says 1 v1 controller can handle 6 mining boards each but when i try 6 i get nothing but "bab0 delay getting work reply" errors allond with a few "accepted" messages but mostly the delay errors. when i remove the 6th board the errors go away. when i use a good board from another group of good miners to make sure the board i added the first time was working fine suddenly the delay errors come back lol….i just dont get it.

I soldered the wire to bring the last boards spi voltage up to 1.7-1.8v and even without doing that it happens so with or without the wire it gives the same errors. when 5 are hooked together in a chain they dont get the error but no matter which chain i use to add the board to the same thing happens in cgminer. I made the changes sugested in this thread too and those didnt help stop them. my pi is at 900mhz so its overclocked and not runnin at stock speed but even then it happens. I cant find any support for these damn things except what this thread has and like before im very grateful that some folks took time to post their experiences about setting these up.

black arrow does NOT reply except for one email that looked more like a sales email for their prospero x-3 and not a reply to actually help a buyer out. ontop of that they wont give the files needed so we can make our own effin controllers cause clearly they didnt make enough to handle the amount of users that fried their controller traces due to hooking them up backwards but with the small amount of support they provided im not suprised so many fried :/.

2. what is the switch on the controller for?? i flipped it on one miner and no matter which way i had it the controller powered up and powered the pi and i havent seen anyone else say anything about it so what does it actually fricken do?!?! its weird….its not labeled at all lol.

3. ne one have any v2 controllers they want to sell??

looking for a v2 controller still.....pm me if u have one.

welllll yes and no. yes they are on amazon but no they are not cheaper. This bundle is on amazon but no one is allowed to sell it except amazon....i know this because i tried listing it there. as for $400 yes there are systems there for that price but they arent the bundles with the camera and the racing game doesnt come with it either not that many care about the racing game im sure lol.

ne one?? the money will go towards vet bills to help fatty.....the bills have piled up to a few grand so far.....its hard to believe she was fine when this pic was taken and all of a sudden she hit rock bottom at such a young age but we r hopin she will recover .
