I have just received it and i try to get it work because i am new in this. I have some noob questions Smiley. First i have this psu

http://www.hardwaresecrets.com/article/402

but i think is in always "OFF" condition and to turn it on you must attached to a motherboard . How can i work psu thinking that is attached to a motherboard to be always on?. I have found this instructions but i dont know if is correct
http://www.electronics-tutorials.ws/blog/convert-atx-psu-to-bench-supply.html
Perfect power supply, can easily power 20 boards and probably more.
And those instructions are correct, connect green to black and the psu will work.

The other questions is that in the miner package was two wires that i dont know the use of them. One other is that the board has two molex. In which one i have to plugged the power?
Those two wires are only needed when you have more than one board.
The black/red wire is for power, and utilizes the green screw terminals on the board.
The other wire is for serial communication, for which we're fine tuning the firmware at the moment.

And the last question is that in the board i see a three pin connector for the fan and in the opposite side a four pin connector that i dont know for what is this. Thank you for any advice
The four pin connector is for the serial communication.
Once you have multiple boards and the firmware is finished you will use that connector.
For now we're supplying USB cables for every board purchased.

Do people who pick up these locally get a discount? Since you don't have to pay for shipping costs? I'm not far away from you so that is an option.
I can give you a little discount, shipping cost is not much for us since we're shipping a lot and we have negotiated a nice deal with FedEx.
Just email your order, specify local pickup and I will get back to you with an invoice that shows your discount Smiley

Just sent an email to [email protected] to order 4 boards.  This is the correct email to order?

You know what I love? Paying on Tuesday, and having my OSM units in hand and hashing on Friday, all the way from across the ocean.

You know what else I love? Lots of parts included! Cords, screws, spacers, fans all included, so I don't have to hunt all over for some little thing.

And they're tiny, and as silent as you want them to be.

And, oh yeah, all in the neighborhood of ~1W/GH/s. I will run these forever. Thanks again!



+1 Ben has it dialed in. This is good for the community.

You're very welcome and thank you for the compliments.
I guess it shows that I am a DIY Wink too.

Be Quiet Pure Power 600W sucks, it only provides 11,5V from the PCI-E and other 12V connectors. Took a Seasonic S12G and this PSU provides 12.1V (max), better  Grin

de 4 DIY1 boards with the cheapo dealextreme 12V 10A PSU is turned up to 12.6V. Now 12 boards are hashing at a total of ± 404GH/s (± 33.6 per board). Next few days more tuning and testing.

Some more testing  Grin

http://miningonmyown.com/2014/03/19/one-string-miner-test-1/

I found out my PSU only provides 11,5V with the PCI-E cables....  Sad that's why these boards "only" hash at 26 to 29 GH/s. I will try another PSU tomorrow.

I also used thermal paste between heatsink and PCB, keeps it some degrees celcius cooler  Grin

Or use an adjustable power supply, something like this one (just an example):

http://www.ebay.com/itm/30-Amp-12-Volt-DC-13-8V-Regulated-Power-Supply-for-Ham-Radio-CB-US-SELLER-/360874766820

Output voltage can be set with a potmeter, so you can easily adjust for
the IR drop in the wiring. And often these are cheaper than PC PSUs.

You will be suprised with the hashrate when the boards are operated
'slightly' over 12 Volts:) Have six of them hashing now with a total of
202.78 GH/s at 13V1.  (Remember this warranty thingie;)

intron




I will test this with 1 board  Grin is 13,1V the max for the boards/chips? I use thermal paste and fan for cooling. What is the max temp? around 60 degrees Celcius?

No idea, I just stopped at that point because the power supply
couldn't handle more current. Current will rise sharply with increased
voltage, please be aware of that!

Start with 12 Volts measured at the board terminals and slowly
increase it with 0.1 Volt at a time. And then observe the board
closely while doing so. But please be careful:)

@Ben @cscape .. any news on when Serial Bus will be working? does this depend on software settings/adjustments for like cgminer of bfgminer?

Serial Bus feature is awesome, if this works we will only need 1 USB cable.
You are correct, it will require only one USB cable for each tower of up to 16 boards.
We are still busy with it, it is working but we're not ready with fine tuning.
Our aim is to get it working without any change in bfgminer/cgminer, but the earlier messages in this thread indicate a change might be needed for bfgminer.

Got my One String Miners today ! and... I loved them ! They are great.

I have 4 DIY1 and 4 DIY2 kits. This evening I build up the 4 DIY2 kits and build a small tower. Quality of the boards and other materials is high. Building was very easy. Screw the pcb to the heatsink, connect the wires to the powerconnectors, that’s about it. I used a BeQuiet PurePower 600W PSU I had laying around. Attached two fans, all in a temporary setup. 10 Port USB Hub is a Rosewill RHB-500. I used an ArchLinux PC, downloaded and compiled CGminer 3.12.3, turned on the miners, started CGMiner and it detected all miners. 3 miners were “ZOMBIE” at first but after just 10 seconds all boards were recognized and hashing. All works great with any issues. Temperatuur is stable with only 2 fans (in the most efficient position), 30 to 40 degrees Celcius. I haven’t tuned them yet so they hash around 25GH/s per board.

Thank you for the compliments.
With heat sinks, the board should do 30+ GH/s each, so no tuning should be necessary.
Only if you want to go way over 30GH/s, you can overvolt them, but that voids your warranty.
Thanks for the nice webpage too, I hope you don't mind me sending the link to some people Wink
Oh, and the boards are designed in Holland, but produced in Asia.


No problem sending the link to people of course. I adjusted the text regarding the production in Asia. Next few days I will do more tests and tuning.

A question that comes to mind does the clock command accept 1 value per chip so clock command for an OSM would be CLOCK followed by 15 space separated values?

Correct. But if you send less values, the last clock value will be replicated for all remaining chips.
