Topic: AlcheMiner/MAT New Firmware and BFGMiner port! (Read 5311 times)

jstefanop, are you still reading here? Please check your private messages, thanks!
And I think it's no problem with rpi as controller but the flashfile is missing. I will pay or donate for his work and the file.

Same problem but I found no solution without rpi as controller. See Alchemist updated support added for RPI with a broke controler

Good question. I hope anyone has more details.

root pw is never set. Log in as admin/admin and set an root pw if needed.
Sometimes its set, but if set, than its root/root or root/toor.

Hello,
does anybody know the root password for alcheminer/MAT miner?
I have make a update and now sudo don't work. I can't make anything.

Or can I reset the System. Or is there a image for sd-card?

Can anybody help?

Hallo,

i'm totaly new in this totaly noob  . my hobby is a bit electronics and stuff, bult my self 3D-printer and co2 lasercutter. but mining is new to my (sorry for my bad Englis, i'm dutch)

last week i buy 2 MAT blades with 2 USB wired to it, the 2 USB goes to a powered hub in to a rpi. so i think (and hope) that the blades have a FPGA update from superman Jstefanop  .

i tray to run it but my program in linux skils are noob, i try to make it work with Minera, but its havy to understand. i reed this post a lot and also the total post "AlcheMiner/MAT New Firmware and BFGMiner Port Discussion" van Jstefanop.

do sombody know a post a bit easier to read oubout this matter, is it poseble to connect the blades to a normal pc, for testing, so that i can learn more about Bfgminer ( i use win 10).
I have a lot questions, but were is a good start for this matter

a play a bit with putty, to tray to install bfgminer (but if i tray to connect to Minera via putty, i stuk by the password, so no install bfgminer custum  )

well you read i m a totaly noob in this materie, but if sombody have the patience and the time...    every tip is welcome

(i have some gridseed 5 chip miners that i connekt to a other rpi and Minera, i works fine. that is my only experience for now)

please help 

thanks for reading my post

Yes I'm here...just PM me :p

Hello everybody,

I'm ready to flash my Alcheminer, only the flashfile is missing.
jstefanop, are you still reading here and would you please PM me?
I would be happy if I got an answer!

Without knowing much about cryptocurrency, my friend obtained a trailer loaded with used mining equipment. There were lots of ASIC devices including some AlcheMiner systems. I think he already sold 1 AlcheMiner before he really looked into what it could do. The one he's left with probably has some bad cards, but we want to see if we can figure out which ones are good or bad. I know even less about cryptocurrency than my friend, but I'll be helping him the best I can. I'll try to familiarize myself with all this and I hope I'm not a burden to you all.

Looking at the AlcheMiner we still have, the boards had already been modified to remove the 8-pin power connections and they were replaced with thick gauge wires coming from PSUs. Because lots of USB UART adapters and rPis were included, I suspect the boards are already running jstephanop's custom firmware. I suspect I'll just have to update to the latest version to be sure.

Some of the hardware is visibly damaged and it's possible all of the boards are bad. If there are failures as we try to set it up, I won't know if it's due to bad hardware or due to my lack of understanding. I'll want to be sure I'm doing everything correctly.

If I understand correctly, the README doesn't really apply for the latest firmware. Is that right? Where should I start?

Thanks!

I PMed you.

hello,

can anyone help me find the Alche_FPGA_v2_flasher.svf file from jstefanop. tried to contact him but had no luck to get an answer.
 i will pay or donate for his work and the file..

thanks for your help,
 stephan

I think the ASIC can bear heatness. The stock Heatsink goes untouchable after few minutes at roomtemp, so it will be 55-65°C on the HS... If i loot at the thickness of thermal grease... than we have realy >90°C at chip and >100°C in the core of chip...

Every solution is better than one 1,5kg Alu-HS with 3mm TG  per board Two boards will produce at all ~500w in heat and a part goes on the side without HS. So we Have 400-450w heat on a 2x huge surface (in relation of for example CPU-IDE with 90W on 10mm*10mm)  



Jstefanop is alive  He got his realy merit coins. Thank you again Jstefanop for your job!

i have tons of fans with Signal and PWM  I can use , why i wanted to see how you used that with one of these and that are better then the ones that come with the miner. i used them on other miners when i had them to cut noise like  s5 s3 etc even lower in noise i had s5 running very quiet the fans run around 2500 to 2800 rpms and not the 3300 or higher whining noise the stock fan had and they stayed below 60 c i would panic if they went higher i know it was over kill but that's was me. you could sleep in the  room next to  5 s5, that how quiet i got them they stayed below 60c .I sold them fast when I sold Off my S5 and stopped mining bitcoins then got luck bought this miner non working on the forums. all my S5 went ROI i never noticed till  a friend asked was it worth it. those were the days cheap miners and you could actually make something and not invest a lot.

two boards on one Hs might be better then two per board or like C1 two boards per HS can't say these things do get very hot

The stock fans from MAT are good and can be very quiet... I remove the adhesive label from the fan and see 4 solder points. Only GND and 12V+ are soldered, we can solder Signal and PWM to the fans  

The costs are for the tooling factory... I dont want use there, but rather make it self. Yesterday i measure the hashboard and will make next days CAD sketch. It possible to make WC-HS on both sides of the board, but i think one side is enough, because too much canals leads to high pressure. The idea is one WC-HT for two boards.
But one WC-HS for each board it easier to realise and assembling...

I make any sketches for all ideas and then you can better imagine and discuss the better idea

I get the same with the service idea so i gave up on that one . or I got some thing about bad links with BFG, i could never fix.
I'll go back one day for the hell of it and do it . when i feel up to it and no i won't get bored trying.

I made ROI on mine and even got a nice feeling by donating a board to a school so I'm good there, i just wanted to cut down the noise more. i have a grind seed i still use form time to time you don't even know it's  running when i use it that i lowered the noise from the loud ass fans it came with, to all most no noise at all, more like normal PC fan noise and my replacement fans run at full speed. i put in bigger much quieter fans .

I mean the big one 25 MH script miner not the little 5 MH one .

I found a few new fans i might try sense i have a window fan blowing on top with the case open i don't  hear over the two stock fans l left in my AlcheMiner/mat miner .

thanks for the idea but it might not be good  sigh ,,, or not worth the cost . good idea but cost to much ? .


Thanks top .

Watercooled miner isnt epic idea ;-) And i think with the heatsink for MAT you cant make money, in best case you get your invest back. I asked an factory for tooling, they say me the mashine costs for me 50€ per hour ... I think we need 10-15min at maschine for each Heatsink part, we need minimum 2 parts.

And dont forget the costs for material...

Thank you for screen instruction, it works :-) But the service dont works... i get everytimes "unrecognized service " by trying to start the service.

cool thanks I'll get them made by shops around me i have the tools, I'm to lazy and very good with designs but not good at designing. I won't steal your idea that's wrong .

yea 7 to 9 inches of paste is a lot .I couldn't believe how much was on mine when i took a board off the heat sink.

I will post the CAD data, if the project starts. But they would be not optimized for perfect cooling, more for making the heatsink "at home" with usual homeworking tools like milling- and grindingmaschine, "tap and die" tools ...
Very difficult will be to make the heatsink planar without right tools. I dont want to use 100gramm thermal compound for each board like factory made by MAT .


I think we take an cooling radiator from automobile... 

if you don't charge to much I'll buy whatever  heat sinks are need from you the vga hs i can get . if you do and are willing to sell a few or share the design il have them made local .

Yes, but i want try your first clue with the bfg as linux service (http://blog.verticodelabs.com/raspberry-pi-bfgminer-service/)

I will try screen, sounds good as firstaid...

that's the only way if you use ssh and want to close it out on your PC and keep everything running, it works with everything big downloads etc..just use screen before you do anything, your set.

Thanks  top..

I will try screen, sounds good as firstaid...


Yes, i think too, that the MAT are the best miner for cheap/free power. And the best way is to use the MAT until they burns away, because at the moment they are powerfull and if the next scrypt generation comes out, nobody want this miner... I run my MAT flashed at clock 352mhz and get with 8 boards 250-260mh/s (336mhz@244mh/s) at pool, but the summer will come. It will produce to many heat, because this i want self made a simple watercool-heatsink at one side (maybe 2 boards on one watercool heatsink) and smal VGA/DDR Heatsinks at other side, that allow to remove 3 Fans and speed down the other.
Remove 3 Fans and speeddown the other will safe >70Watt and i can go with the clockspeed higher than 352mhz. I want try to target 384mhz and expect 280-290mh/s

The jstefanop flash is the lifesaver for MAT, without flash the MAT are unusable for most pools (->30% rejected on clever without flashing)
