[DIY] - Reward $100 | Antminer S1/S3 Blade on Raspberry Pi

[J4bberwock]

And my best results are with this command line:
cgminer.exe -o stratum+tcp://thepool:9999 -u Jabberwock -p x --bmsc-freq 0F81

giving the following result:

The pool is getting nearly 50Gh on each panel, 100Gh stable, it's slowly going up.

Edit,
I'll try the chaining this afternoon with a second S1 that is supposed to be dead, just in case it was the control board that failed.
But first, I'll need reflowing the same CP2102 as on the first board since only 1 is detected.

Correct me, but it seems there are ~60% of errors at AMU0 and ~70% at AMU1. It is not 42 at the end but 16 resp 12 GHs at pool stats.

You should be right about the pool stats, and they should be even worst since the accepted are multiplied by the difficulty, and the HW errors, but for some reasons, I'm getting 90-105 GH on multipool.
And it's my only miner on this pool.

I run one board using an el-cheapo CP2102 and WITHOUT a heatsink and got thus:



Obviously, the errors are way out there (due to the lack of a heatsink, I think), but poolside speed was 44 GH/s @ freq 400 (average in an hour) with:  -o stratum+tcp://stratum.mypool.mine:3333 -u pekatete -p x --bmsc-freq 0F81
I am currently running with --bmsc-freq 5081 (i.e freq 425)

So I am at a loss as to why some people are only managing a miniscule 12GH/s on a board .... care to share your settings / software / etc ... ?

J4bberwock -  way to go! now for the software ..... but seeing what i am getting from a stock cgminer without a heatsink, I am hopeful to be able to squeeze a bit more with one on, which, aside from the fun of it, may be a done deal!

Not sure what you mean by "from unit", but I can tell you that the board is NOT pencil undervolted.

Anyhow, having run the board with --bmsc-freq 5081 for the last hour, I managed to reap a poolside average of ~20 GH/s (despite cgminer showing an average of 99GH/s +), and as soon as I turned it back to --bmsc-freq 0F81 (with cgminer showing an average of 66GH/s), the rate started rising again! So that's sorted for me then ....

I'm using the same settings, but only getting 45-55GH on each board in cgminer and poolside, with less HW errors and boards that weren't voltmodded. (heatsinks are on, as you can see on the pics.)

That may be reason for concern then .... I was hoping to be able to squeeze some more speed with the heatsinks.
I have to say that whenever i run this version of cgminer, it seems as though it is another program altogether! I was getting frequency messages before and now I am not getting any, but a repeated error message Bitmain detect <7:2> failed to initialise <incorrect device?> in between the Accepted messages!
Something else that may be relevant to the above is that before I reset the freq, I mistakenly moved the connection from the CP2102 to the board and cgminer "lost" connection to AMU 0 but quickly found AMU 1 ....! Anyways, after restart it is back to AMU 0 but with the error that does not seem to be affecting the board's speed (still early days though).

i have a few ideas than im going to test when i get home (and also have some cp2102s in the mailbox) - since i have 20 boards, im willing to do a little risky testing on a few of them, i will post my findings whenim home...

[pekatete]

... but a repeated error message Bitmain detect <7:2> failed to initialise <incorrect device?> in between ...

OK, I found the reason for that and it has nothing to do with the S1 board. I have a few NF2's which also use the CP2102 and had not unplugged one on the laptop I was running the board from (though it was not hashing at the time). The messages have stopped since I removed it.

I was wondering, if J4bberwock's board could do with some firmware .... possibly implementing the bifury protocol (I am simply grasping at thin air here seeing a fully heat-sunk board is only hashing at 44GH/s).

0981 - 250 - 50GHs - 84W - 0.02% HW
0A01 - 262,5 - 52GHs - 88W - 0.13% HW

With precompiled version 3.8.5 there was ~8% hw errors, after compiled version 4.7.0 there is ~0.03% hw errors (api monitored and run per hours). It makes ~50GHs/84W, blade was pencil undervolted, with version 4.7.0 it is near to original efficiency. I will probably buy another cp2102 and try to run 2 blades each connected thru its own cp2102. Unfortunately API does not show temperature, any idea which pin is carrying that?

Nanofury2? Not a cp2102, but an mcp2210, similar numbering

[helipotte]

I have a TON of old Block erupter USBs.  Could these be modified to work?  They appear to be cp2102 based and the extra parts can easily be removed with a rework

station.

It could work, but you need to find where to solder your TX and RX.
I'm not sure there is a full schematics for it.
Just had a quick look at one that was laying on my work bench, and Tx/Rx seems to be connected to IC3.
Good luck soldering wires there.

Let say, this is clear: PIN3 - RX, PIN4 - GND, PIN5 - TX, PIN8 - GND. PIN2, PIN6 and PIN7 are not connected anywhere. But what is PIN1? Where do You connect it?

pin 1 is the PWM signal.
I use it to regulate the speed of the fan.

It means it is temperature?

[J4bberwock]

It means it is temperature?

not the temperature, but the pulsed signal that tells the fan at what speed to spin.

Here's your heat sink.

https://www.onlinemetals.com/merchant.cfm?pid=1162&step=4&showunits=inches&id=997&top_cat=60

Just drill a few holes in it, and run some water through it. I designed a waterblock a couple of months ago but it would have cost around $80 to make. I gave up on it for a while and decided to make my own. I borrowed a buddy's drill press and tried to go the long way. I ended up going through one of the sides. I only ordered I piece of metal, so I put it on the back burner for a while. I thought about routing a piece and using another thin piece to create a channel, but I don't have access to a cnc machine. For mounting the boards I was going to drill holes all the way through and use a machine screw and nut with nylon washers to pull the boards tight against the waterblock. If anyone has access to  machining equipment and can make some simple waterblocks for a reasonable price I would be interested in a few.

Great job J4bberwock for getting a control board together. I wanted to do it, but I'm not that smart.

Same here! Compiled under MinGW but will not detect the devices!

I am running 2 boards without any heatsink, fully powered but with a 150 CFM fan at full blast blowing over them. I have seen average speeds (poolside) of up to 106 GH/s (when I set a high minimum diff), and ~85 GH/s when the pool sets the diff.

One anormally though is that, using the precompiled version 3.8.5, I can not have two CP2102's in the same computer. I can hav one pluged into the PC / laptop, and another plugged into a hub connected to another usb port then it is ok. Also, I can not start with both plugged in, I have to either start without the modules pluged in, or just one module, else cgminer crashes!

J4bberwock -  do you have similar issues with the board? Also, I put myself down for the protos (also to work on windows software, sorry not a C++ geek yet!), are we ready to go and do I need to cover your postage / outlay?

PS. zziggi - how are those heatsinks coping? I have seen some heatsinks 300mm X 140 for approx $15 each, also for normal operation, syscooling do the C1 heatink for $49 (I think + shipping) ....
