you need a monitor initially because it's IP address is unknown and even a scanner cant't find what has not been set.

I grabbed a TV and hookup it up via hdmi and had it running in about 45 minutes then it went to my always cool and dry basement where the mining equip is located. I give mine a static ip so after a reboot I always know where to find it.

ok - I just followed the directions on Post #1 of this thread for: STEP BY STEP RASPBERRY SCRIPTA INSTALLATION

and cgminer started right up

and is running just fibne

two questions - can it be run nohup - so that it can run even when I don;t have an ssh session?

and #2 - how do I get it to run and mine BTC simultaneously?

by the way - my pi rasberry is running 20 gridseeds

Jeff

Yeah I think I'm going to buy a raspberry pi now and scare my wife :p (as if a bunch of antminer s1s and 11 gridseeds weren't enough... well she did marry a geek) ... all you see is an sd card, sd card reader/writer, charger, ethernet cable and the model b, right? Do you initially need a monitor to set it up or can just remote login via ssh?

I have not heard a single good thing about the zadig software and everyone says to remove it, but I want to mine BTC and LTC on my gridseeds on my pi rasberry - has anyone figured out a way around the zadig software?

yes - the recommend an 8 gb card - I bought one with the card and a 24 port hub.

Sorry can cgminer control more than 10 gridseed? Whenever I add an 11th, it does show up in cgminer with hash rate but never accepts anything?

GSD 10 is the one. I added them one by one with cgminer running

Here's the command line options to run cgminer:

--scrypt --gridseed-options=baud=115200,freq=850,chips=5,modules=1,usefifo=0 --hotplug=1

I can't even get cgminer to run i pi rasberry - just hangs

Not really sure what I am doing wrong with CPU miner I am getting no accepted shares. Stratum is detecting new blocks. It does say it was unable to open the comport "GetLastError=2". The miner is on com4 and that is what I have the bat set to. Same issues with CG miner. Think maybe I have the drive installed incorrectly, any insight?

Buying these for < $100 would be nice. If anyone has any suggestions on how this can be arranged - please let me know.
Where can we purchase the chips wholesale? Alibaba? Straight from the manufacturer?

You can get them directly from Gridseed:

Hope the following information will answer you your question and beyond.
A: the MOQ (Minimum Order Quantities) is 500 units
Q: what is the price?

#500-999 units: 158 USD /unit
#1000+ units: 155 USD /unit

They won't ship it to you. You need to organise everything but hey, pretty low price compared to all those m'fos selling 1 unit for 350$ + Wink

Do you mean the entire unit including heat sink or just the completed and fully functioning pcb?
Can you tell us 'exactly' how this can be accomplished?
Who to contact? url? email address? etc.?
Thanks
Wolfey2014

I contacted [email protected] and got the quote for 500+ units at $158. These are the full version with heatsink and fan, not just the boards. No cables, psu or wiring, just the round GS unit only.
Downside is they only deliver inside mainland China. You would have to either go there or have someone forward to you through Hong Kong. Getting across the HK border is fairly easy, but then you hit US customs and their fees/taxes.
Hey, if anyone has a trip planned to China, we could put together some sort of group buy and that person could arrange the shipping from China...

Or you can do bulk orders through www.HASHRA.com
Probably get the same or better price without any shipping hassles.
They are GridSeed's main ww distributor now.
They are supposed to be taking bulk orders by now.
I don't know what the hold up is.

What I was talking about was getting just the PCB with firmware ready to go minus the heat sink etc. for running Scrypt only. Should be around $50 to $70 each, I would guess.

images to follow later.

I really hope these images include pool stats confirming your hashrate. A lot of people in this forum have been running their Gridseeds without fans at all, so it would be really surprising to learn that repositioning the fan can gain 20%+ performance.

It doesn't. Cooling is not the the problem in scrypt only mode. You can remove the fan completely and in scrypt mode the heat sink will barely warm up. In fact, you can run scrypt without a heat sink at all. The power draw is so low in scrypt mode (approximately 7 watts without the fan) the chips don't even get toasty. Use the heatsink and fan to keep your beer cool.

The heat sink and fan are for bitcoin only/dual mode. That will heat things up (I haven't tested it myself, but others have reported a 60 watt draw).

Considering the number of people who have tried pushing these things to their limits, I seriously doubt claims that these things can be run at anything above 900 with any sort of efficiency. The people on this board aren't stupid. I'm waiting to see what this guy posts. I'm betting he'll have a hashrate of 450 kh/s but almost no submitted shares due to rejections and errors.

Running these at 950 MHz with voltmod, no HW errors, removed heatsink but fan spinning. Uses around 10W, chips are cool to the touch.

Link to the Voldmod thread.

https://bitcointalksearch.org/topic/gridseed-5-chip-usb-miner-voltage-mod-519112

My point is that messing with the cooling has no impact on stability or performance whatsoever, even when overvolting.

I was thinking earlier, for Scrypt only operation, one could simply pull the cards off and use them without any heat sink attached at all.
Would save a ton of space but also, waste a lot of the money we paid for them.
I bet the cards themselves are $25 each to make and maybe $50 wholesale, figuring a minimum 100% markup by the manufacturer.
Then one could line them up in a row and blow air from one fan on them all, keeping them at nominal and safe temps.

Options options....

I do like the idea of overclocking the little suckers though. The higher the hash rates, the more money they make, obviously.

So to summarize: the max you can get is about 360kh at clock 850 without doing a hardware voltage mod?

Yeah that was my point.
