So is there any way to control the fans? (cgminer, wiibox...?) automatically or even manually?

thx a lot .. will update this ... :-)

You can set voltage=1 in your config, but it turns out that will actually lower the core voltage.

How to get Scripta working as it was intended

Follow the instructions by Darkfriend77 below but when you get to step 6, go to directory opt/minepeon/bin and remove the original cgminer there (rm cgminer). Now copy the new cgminer into this folder to replace the original and chmod it as below.
Now go to directory opt/minepeon/startup and edit the file miner-start.sh with nano.
Change the line -
to
Lastly apply the stability fix.
Now you can close ssh and restart your pi and it should automatically fire up your gridseeds and start mining.

I bought this one:
http://www.amazon.com/CanaKit-Raspberry-Basic-Clear-Supply/dp/B00DG9D6IK

Includes power supply and case. If you don't need a case and have a spare micro-USB power supply, you can get a bare board for ~$40.

You will also need an SDHC card (full size, not micro), 8GB or larger.

Any thoughts of how to raise the usb limit in linux above 99?

Has anyone figured out how to overvolt yet?  I see this in the gridseed driver...

typedef struct s_gridseed_info {
   enum sub_ident   ident;
   uint32_t   fw_version;
   struct timeval   scanhash_time;
   int      nonce_count[8];  // per chip
   int      error_count[8];  // per chip
   // options
   int      baud;
   int      freq;
   unsigned char   freq_cmd[8];
   int      chips; //chips per module
   int      voltage;
   int      per_chip_stats;
}
Aand later on this method:

static void gc3355_increase_voltage(struct cgpu_info *gridseed) {
   uint32_t reg_value;

   // Put GPIOA pin 5 into general function, 50 MHz output.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, ®_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA CRL register from %i", gridseed->device_id);
      return;
   }
   reg_value = (reg_value & 0xff0fffff) | 0x00300000;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA CRL register from %i", gridseed->device_id);
      return;
   }

   // Set GPIOA pin 5 high.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, ®_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
   reg_value |= 0x00000020;
   //reg_value &= 0xFFFFFFDF;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
}

Looks to me like we pass an int as the argument voltage and it will add it to the base voltage value(which i think is set to 0, if I'm reading the header right), maybe?  But then it also says gpio(general purpose input output?), which is usually a general purpose pin header on the pcb itself, right?  I'm no developer/hardware engineer, anyone want to comment?

What raspi are you guys using? I've never used one but contemplating it now.  If someone could provide an amazon link that would be great.

EDIT: Also there is no way to use the lightningasic update for the gridseeds at this moment because the chip used for usb communication is different.  I guess only time will tell if we will get updates on these.

About halfway down this page there is a post on how to set it up on the Pi. I did it earlier today and it worked excellent.

I've been thinking that. Which brand of Linux would you recommend?

Unplug the power from your hub, start cgminer, and plug the power back in your hub. I have 20 running in cgminer 3.7.2 and that is the only way to get the to work. Chang hotplug in your bat file to 5.

Use a Rasberypi and linux

My gridseed miner uses ST32 Virtual COM Port, and at the moment cgminer-3.7.2 doesn't detect the device. I've updated its driver by zadig, but still no luck. What is the solution to this?

Just curious what everyone is seeing for the speed on a single gridseed scrypt at the pool. As in if it is showing 360 on CGMiner what are you seeing at the pool on average?

I tried to flash the firmware on my gridseeds but couldn't get it to install the included driver.  I had to take the heatsink off so that I can get to what I assume is the same "white" button the documentation refers to.  It then proceeds to show up as an unknown usb device under windows but I can't go any further than this.

EDIT: I only say this because of the following:

Nice rig!
Why 6 psu's though?
I mean, each PSU is designed to handle 10 GS5's.
Especially now that you're running Scrypt only.
You barely need one psu for the whole smash!
Wish I was hashing at 11MH/s! Makes me envious!

I have two wiibox controllers available if anyone is interested.

Just the controllers and the wall plug. You will need a USB 2.0 A Male to Micro B (5-Pin) cable to connect the wiibox to the wall plug.

Paid $100 each so make me an offer

Sorry if it is bad form to post this here...will delete if it is.

Using a GPU rig which is off to the side

Cant wait to get the other 45 plugged in.

Kindve high stales. Gonna restart everything for the first time here in a bit. been running for 5+ hours just fine.

Nice work chap, will be good once they are all powered. What controller are you using? 

Only 35 running right now and 60 of the total 80 i will have. Need more barrel plugs the chinese vendor screwed up
