We are very pleased to announce our latest versions of the HASHRA CONTROLA Firmware for your Gridseed Miners using the Raspberry Pi including the BLADE.

We now have our CONTROLA firmware in three flavours:

MINI CONTROLA:
This is based on our first Controla firmware and continues to support dual mining with the "Mini" 5 Chip Gridseed USB Miners.
Now with pool failover support.

BLADE CONTROLA:
This is our new firmware that works just for the new Gridseed Blade.
One of the key features of it is that it calculates the pool hash rate to give you a more accurate "actual" hash rate at the pool side rather than just local.
We are obviously still working on this and developing it and will making many updates to it. First tests seem to show it maybe possible to run 10 or more BLADES off one Pi using BLADE CONTROLA. : )

ATLANTIS CONTROLA:
This is the firmware designed for our Limited Edition (Already Sold Out) Scrypt Miner.
This is based on the MINI CONTROLA without the option of Dual mining mode.

All these can be downloaded right now at hashra.com/support (http://hashra.com/support)

We will also be putting up new "Set up guides" for our miners very soon. : )

UPDATE:

Good news Ladies & Gentleman…

We have now decided to release the SSH login details for the Gridseed Based products using the CONTROLA Firmware:

USER: pi

PASSWORD: 3K4Hb8FMeZjQZJEX6scYzZa

ENJOY!  :)

Can you upload a mirror link? The dropbox one is restricted  downloading at 125KB/s

Thanks, downloading Blade Controla now.

edit:
Yes, this is good. Only if I could set the clock speed to 838Mhz, which seems to be the optimal to stock Blades.
How about adding "professional settings" (with a disclaimer ofcourse), from where you can finetune the frequency as you wish?

Can you please add 838freq? This is the most stable freq for blades has 800 is too slow and 850 causes too many hw errors.

Hi is there a place to get this the link is over loaded it seems

what a great Program thanks guys my grids have never ran better or longer looking for ward to get more from you

thanks Danny

Yes,please add 835 and 838 frequency,Thank you.

Working on getting the firmware to do 838... will keep you posted.

This will arrive in a simple update.

+1

and thank you :)

any update on 835 and 838 frequency?

963, 975, 988 would be nice to have too...

(that's 24hrs 24mins)

Working on it so the update releases out this weekend… though please do not hold us to that.
Still got some more tweaking to do with it so it is ready for you.

Will have more options for frequency control.

Wow, nice hashrate, are your blades modded? how did you get it to run stable on that frequency?


Below the new frequency table for our forked bfgminer (not done with the latest firmware yet though, need some time to make it pretty :) )

HASHRA: Good to hear, some finetuning options are always welcome.

maxzilla: This is voltmodded with 39kOhm resistor(s), there's a thread about it in here (https://bitcointalk.org/index.php?topic=576784.0).
950Mhz in Controla is good with very litte HW errors, at 1000Mhz Blade just doesn't start hashing.

Please make sure you update now to version 1.4.5 for your CONTROLA by hitting "Update Firmware".
This is for BLADE, MINI and ATLANTIS.


We have now added more frequency options. (Magic number for BLADE is 838)

Advanced settings section giving individual clock speed control.

New drop down menu for easy selection of clock speed.

Now comes with per "Miner" control.


Good Luck!  :)

Absolutely brilliant!
On-the-fly & individual clockspeed adjustment is just awesome.
Hoping to get 6.5M from my Blade now...  ;D

Hi there - what fork of BFGMiner is this? Do you have a URL?

Hi, this is the url of the fork
https://github.com/HASHRA/bfgminer

I made changes in the /feature/gridseed-support (v 3.10) branch
I tried modifying the gridseed-support-new branch, but for some reason it was not performing as well as 3.10... on the pi at least.
  

There is official support in BFGMiner for GridSeed devices. Why fork it instead of contributing?

There was that note on the pull request that luke left mentioning he moved support there temporarily, only the note was there a while after it was merged in

I'll have another closer look at 3.99, The clock setting is already dynamic there. I added the chip amount setting in the fork, I don't know if that is something that you are interested in having?

Thanks - maxzilla and I have been talking in PMs.

I was just trying to avoid what seems like an unfortunately common trend (at least in this mining space) of forking projects to make something "new" rather than contributing back to the original project. I don't think that's what max was trying to do.

Thanks bud, will give it a try again:-)

Is there any reason why I cant run a 5 chip gridseed miner along side a g-blade using the controla for g-blade? has anyone done this? I would like to free up a r-pi.

We had to make some changes to the firmware for the Blade to get correct readings so I'm afraid it cannot be used to run the 5 Chip Mini units also.

Sorry.

Whats the latest version?

1.4.5 for 5 chip

1.4.5.1 for G-Blades

May be HAHASH use wiibox miner....so many hw~~not stably.   but still use 850MHZ..


can hahash change cpuminer by sandow ?

Correction:

You can actually use it but the readings will all be wrong in Controla, you would need to get the readings from the pool side.

Anyone else with Problems while adding new Pools to the List in Hashra 1.4.7.1

It doesnt show up in the List "Pool".

So.. I bought a Pi B+ and loaded up Hashra on my 8gb micro sd, booted and... uh oh no keybord/mouse or network.. played a few hours and figured out there are changes to the firmware required when booting raspbian.

Downloaded latest raspbian, overwrote my sdcard boot directory with the new files and success!

Next mission, get all 10 of my Minis operating, was pretty simple. Decided I want to update Bfgminer.
Managed to compile 4.6.0 and replace the stock version in hashra. Had to modify the LTC section of miner.class.php to remove the gridseed-chips= part as it isnt required and would throw an unknown command error trying to run Bfg.

Bonus to updating to 4.6.0, the log now shows the size and difficulty of each share accepted, and also shows for which chip on which mini!

My next task for my little Pi was to add my lonely Antminer U1 to the powered hub, and give its own instance of Bfg in the background to pump a little extra sha256 ( the minis are doing just scrypt, I have an Antminer S1 doing Sha256 duties) Success! Added the seperate bfg instance to rc.local and connect to its Api using Awesome Miner to keep an eye on it.

Only issue I have got right now is that if the U1 is plugged in to the Pi either direct (bad idea power wise) or via the powered hub, the 9 minis also on it (1 mini is direct to the Pi) dissapear in the Hashra web interface. They stay connected and continue to show shares accepted in Bfg on both the Api and the Log on the web interface.

The mini directly to the Pi stays visible, so i can change its frequency, has its little circle and hashrate showing etc. The overall stats above still update correctly as the sum of all 10, eg Total Hashrate shows as 3.6Mh, total accepted/rejected shares shows correctly, as HW errors come up they show correctly up the top.

Connected to the Api via Awesome Miner I can see each individual mini, its accepted and rejected shares, and its HW. If i unplug the U1 and refresh the webpage, the other 9 Minis reappear and i can change their settings etc. If i have the page already open and plug in the U1 (doesnt matter if its hashing or not) all 10 minis will stay visible on the page until i either refresh or move away from the dashboard (to settings etc, also includes the "restart miner" "reboot" buttons etc)

Anyone got idea's? Im relatively new to Crypto currency, havnt used linux much, and have zero knowledge of web / php stuff.

A few pics to give an idea.

Just plugged in (The Minis are all still visible, but the stats no longer update, just the log)

After a refresh of the browser, the stats now update as expected, however only the miner not on the powered usb hub visible.

Hi,

Are you able to confirm which files you replaced?

My SD Card only appears to have the files in a single directory?

.fseventsd

pretty sure it was almost all of them, its essentially the entire boot directory
