Anyone have a good source on USB cables that actually fit correctly? I am tired of cutting the ones I'm getting with the miners down to size. I had one from an old HD that actually fit perfect so I know their out there.

This one looks promising but way too expensive:

Do these from monoprice fit?
http://www.monoprice.com/Search/Index?keyword=usb+a-male+to+mini-b

I bought the monoprice ones with the ferrite core and the connector is just barely too big, very snug fit. However, you can just bend the fins on the heatsink out of the way, right above the usb port, and then they fit great. I also have some of the monoprice ones without the ferrite core and they fit fine with no modification.

Thanks. Did not see the version without the ferrite core. Will order those to see if they fit better.

Edit: Just spoke to one of their reps using live chat. He said he compared both versions and they have the same size covers on the Mini-B side. Sad

Not sure if I should believe him or not Huh

Edit2: Went ahead and ordered 20 to see if they fit.

I bought 20 of these:http://www.monoprice.com/Product?c_id=103&cp_id=10303&cs_id=1030302&p_id=107&seq=1&format=2&utm_expid=58369800-11.R-enhtUGRrSdHz5vzpVS2g.0

They work just fine.

A shot of my 30 Gridseeds up and running. All clocked to 850Mhz, getting about 11Mh/sec out of it, running cpuminer/batch files.
When I put it together I wanted the choice of mining other sha256 coins. I will probably forget about that thought and switch to standard atx PSU when cables are available. I left all of the fans in place in case I did want to mine non-scrypt and also did not want to mess with putting them back if I sell these. I am using (3) Rosewill RHB-500 USB hubs, loaded with 10 on each. This includes a 4A power supply and have been working great.

Not a bad cost effective solution using (3) modular storage racks that lock together. $5.88 each. Some wire holding pus's in place and double sided tape on the hubs.

Anyone tried to flash the firmware of the miners? I've read the manual from LA but it looks like something I wouldn't want to just "try" for fun

So far I can't find out which firmware is on the gridseeds anyway so can't see if I can upgrade anything.

I'd be willing to give the firmware flash a go. Gota link? I've looked everywhere and have not been able to find any info on a firmware update for these things.

http://www.diffpair.com/lightningasic/

Which is the link that LA provided with the firmware stuff. Got it from this post: https://bitcointalksearch.org/topic/lightningasic-usb-miners-based-gridseed-gc3355-tech-support-thread-477709

(and here confirmed that it's from LA: https://bitcointalksearch.org/topic/lightningasic-la100m100mhs-scrypt-miner-usd1999-la1ths-usd1750shipped-out-421921)

Hi all,

does anyone know if it is possible to have the Gridseed Miners do scrypt-N or scrypt-jane? A new firmware would be needed I suppose.

regards,

P.

wtf I can use CGMiner now?!

I am going to donate now kvclivas or whatever it is

not ckolivas, some one forked it for gridseed, as ckolivas said he wont work on any other except sha256 after 3.7.2

I am getting HW errors running 6 gridseed miners in cgminer.
Anyone getting HW errors?

I have one that has HW errors and the other works fine... Maybe it is a Gridseed thing?

regards,

P.

Why so difficult? My USB cables fitted fine. Just push a little harder, so you bend the fins of the heatsink a little if there is not enough room.

I did remove all the fans ..

and so far working well ....

https://i.imgur.com/rOh2iIWl.jpg

I just stripped one 5 chip down, removing all fans and heatsinks. I then proceeded to start mining scrypt with it at 850. I let it run for about 15 minutes, and using the touch test to see how hot the 5 chips get.

They don't. Basically warm to the touch. I don't think these need cooling for scrypt only. I'm definitely taking the fans off all of mine, and if it ever gets to the point where they take up too much space I'll take off the giant gold sink and put the little per chip heatsinks meant for asicminers/vram.

I understand why gridseed has the cooling on them for the SHA side of it, I just wish there was a cheaper option for scrypt only with no fan and small sinks.

Maybe one of the resellers can convince gridseed to just sell the boards, I'd buy some that way.

Reused a gpu miner frame i was building for a couple 7850 i would going to order.

https://i.imgur.com/5bb5629.jpg

can hold a total of 18. 8+8+2 , 1 psu, and space next to the psu for usb hubs. Was short on material but it will have another rack on the top .
total overkill, but material was cheap. im sure i could find a way to fit more if i turned them on the side but, 15-18 of them will be just fine for now.

Anyone Come close to 400kh/s yet? Looks like most people are running about 361kh/s .

Nice layout.
One fan cooling all 10 pods. Nice.
I'm cooling 5 pods with one pod with fan in the center and 4 pods without fan surrounding it.
Running at a decent 80* to 91* F in Scrypt only mode.
The cool air that the center fan throws is enough to circulate some air around the other 4.
They're all within 1* of each other.
I'm testing their temps with an infrared temp sensor gun.
So far, so good.

Thank you darkfriend77! this is a great guide!
We will try to release a new version of scripta where people don't need to do all this... Ideally Scripta should be able to discover different hardware devices (gridseed 5 chips, dualminer and others) and associate each device to a cgminer and a set of parameters, along with the pools the dev should mine on. We have posted a TODO file on github about this and if someone wants to join the team (also for other aspects) please feel free to send me a PM or play with the Git! https://github.com/scriptamining/scripta/blob/master/TODO
P.S. Apologies if slightly off topic, but I thought it was relevant...

Edit: Some stability issues have been reported and qiqiji on the litecoin forum has suggested to make this small change to the file cmdline.txt
https://litecointalk.org/index.php?topic=9908.msg139447#msg139447

Step by Step Raspberry SCRIPTA Installation:

1 - SD Formatter (link) clean up your SD Card. At least a 4GB SD.
2 - Download the SCRIPTA Image (link)
3 - Win 32 Disk Imager (link) and write the scripta image on the SD Card.
4 - Put the SD Card into your Raspberry.
5 - Use WinSCP to move over the latest rasp cgminer for gridseed (https://db.tt/UygLkqwd) or Use

Code:

wget https://db.tt/UygLkqwd -O cgminer

6 - Go to the location where you copied over your cgminer and do "chmod 777 cgminer"
7 - Go to the SCRIPTA Web GUI, under Miner hit Miner commands, STOP
8 - Go to the location where you copied over your cgminer and run it from there using these commands:

Code:

./cgminer --scrypt -o -u -p --gridseed-options=baud=115200,freq=850

I have the same freezes with cgminer on Raspberry as reported, but I also keep connecting and disconnecting miners and after a while cgminer crashes due to Segmentation Fault. I'm afraid that means I have to format the SD card and reinstall (and make an image of the status at that point.

Due to travels I'll have to let these alone for a while so I'm thinking about buying the cheapest laptop with windows and connecting them to that as there's at least a working version that doesn't crash on windows (and I don't have the 2 levels depth maximum hubwise that the Pi has.
Plus I'll have easier remote access than with a Raspberry and a few controllers from LA.
