Hello,

Does someone has a idea how far you can drive ( voltage and frequence, resulting Watt/miner ) an S1 and a S3 ?
Power (electricity ) is no issue but noise is, so I would like to run then without 'forced' air ( = fans )
Would like to use them as 12 V electric convectors Grin

Hello.
After reading large amounts forum all the time I have a problem with running blades S1. I currently have Raspberry Pi with four converters UART with PL2303 chip.

I tried to change the PID and VID in usbutils.ci and 01-cgminer.rules but the blades are not recognized.
Do any of you can write a step -by-step with what parameters should compile cgminer .

Here is simplified circuit of level shifter.This is close to that BM used.Caps are ceramic.

Now I get it. I have those step-downs too but I decided to keep my construction as simple as possible (and cheap).If you make your own pcb:s, you dont have to connect all of those gnd-pins.One gnd per connector is enough.It's easy to add those missing groundings to top layer if you decide to order pcb's from factory. That drops quite many jumper wires from your design.And s3 blades do need that 3v3 line.Not sure but I think that atleast tmp chip is powered with 3v3.Not sure though.

As i said in the post im using these for regulators:
http://www.ebay.co.uk/itm/2pcs-lot-S2-DC-DC-StepDown-Adjustable-Power-Supply-Module-LM2596-/252088850843?hash=item3ab1aa999b
they fit in the squares where you see 12v in ...3.3v out..etc

I saw 3.3v on the pads on the S3 blade, figured it need 3.3v too, didnt think it was a actuall loopback.

Only one side because it will be Home made/self made pcb.

Any suggestions are welcome

Thanks for the info.
Here is my crack at the thing:

photo uploading websites

One layer, lots of jump wires, hope it works.
PCB and holes are S1 and S3 compatible.
Going to test this week.

for 1.8v and 3.3v

I like your idea to make it as exact fit to original s3 mounting brackets. But there are a few things I don't understand. I don't see any regulators.How are you feeding those 1v8 and 3v3 lines.
If you get them from external sources then what is that 12v rail for?12v is only needed to create those 3v3 and 1v8.

S1 controller only gets 3v3 line from (s1)hashboard and it's in separate cable.
S3 hashboards don't have 3v3 at all. It only feeds 12v to s3 controller which has step-down to 3v3 and 1v8 lines.Those lines (pins 3 and 4) are then fed back to hashboards.And these 12v,3v3,1v8 are all in that same 20pin cable.That's why it's so easy to burn those s3 controllers.Connect cable wrong and poof,atleast controller dies,sometimes blades too.

And why not to make it double-sided? I even don't know factories that make one sided pcbs. It's much easier to design pcb using both sides.No need for jumper wires.I also designed my pcb pretty much one sided just to make it easier to etch at home. I just left all but absolutely needed groundings away. Ofcourse I added them to the pcb which I ordered from factory.

niiiice, but i dont know any cheap making pcb bussineses

Do you have more?.. for sale of course.

try Dirty PCBs - they are dirt cheap!
@pinhead666 - are those the ones you used?

I ordered from Itead. It's cheap and took 15 days from sending files to have them at home.I got some RPI oled add-on boards too, as a gift I think.

I think you have missed this thread completely. https://bitcointalksearch.org/topic/diy-s1-to-s3-adapter-board-1164015

I just today received these pcbs and I have about 20 pieces to sell. Ofcourse I can make more but since connectors are pretty pricy I don't buy them more than I need/can sell.
I'll post pics soon as I assemble one with mounting brackets. I already have two of these factory model adapters running as I'm testing them. So far no problems at all.

I can confirm that the last schematics works even with transistors like BC547...BC550.
Thanks for the info.

C1 blades are exact same but connector is other side.I don't have C1 controller but it has different cables, I think.I am currently running one c1 and one s3 hashboard with my s1 adapter. Cable for c1 board is my own made.S3/C1 blades have that nasty 12v rail in pins 1 and 20 and connected wrong it sure blows controller.

pinhead666 as you have the gear to test, can you confirm that the C1 blades are the same as S3 just the connector is on the other side?
I managed to blow up an C1 controller conecting it to an S3 blade...sad face.

Is there an adapter cable that will fit the S1 pinout? The cable that comes with the CP2102 is of heavier gauge and doesn't fit properly on the hashing board.

These fit. http://www.ebay.com/itm/321827313187?_trksid=p2057872.m2749.l2648&ssPageName=STRK%3AMEBIDX%3AIT

Thanks, ordered a few.

Thanks, im working on a variant myself and needed to know the values and what you have learned from experience.
The chip fring thing is good to know.

Thanks.

Schematic is just fine,problem was loose connections on my prototypeboard.And I've learned that if Tx is connected but Rx isn't, it will fry chips pretty quick.I had mb failure and had to do clean install of windows 10.And there went gerber and schematic files of my PCB.Link to schematic photo: http://kuvapilvi.fi/k/ynyF.jpg

Transistors are 2n3904,ic1 is any 3v3 TO220 reg (but you may have to reverse it,different pin-outs available,the one I used is 4-legged with on/off function) and ic2 L1117 1v8 sot-223 or d-pak.
R1,R4 = 1k2
R2,R3,R6,R7,R8,R9,R11,R12 = 1K
R5,R10 = 33K
ic2 isn't shown in that pic 'cause it's at the bottom side.Both sot 223 and d-pak fit.

I made more changes to that pcb (same schematic though but maybe little different component labelling and added some smd caps) and here is pic what I should get from factory. http://kuvapilvi.fi/k/ynRo.bmp
They should arrive next week.
