If the OP is not interested then I might be interested in your equipment.  What are you asking for your rig?

CreativeReef

I am not the OP but I am interested in old FPGA equipment. What are you asking for your Cairnsmore?

I recently acquired a Block Erupter 49 port USB 2.0 Hub Rev 2.00 (Red board) to use with my 2PAC and Terminus pod that I purchased from sidehack as well as some miscellaneous USB miners.  Finding information about these hubs are more elusive than I imagined.  Does anyone know of a support thread or other resource to post my questions to?

1) Who was the OEM/Primary distributor for these back in the day?  Asicminer? Eyeboot?  Someone else?
2) The unit has what appears to be a 25A automotive style fuse.  Does that mean that is fused for 12V 25A?
3) 25A would only allow 500mA per port with only 500mA extra to handle startup surge.  Does that seem right?
4) Is it likely that the traces would allow more power than 500 mA if the board's total power rating is not exceeded?

More goal is to run more 2PAC and other USB miners as the price is right and I acquire them.  I should have asked what fuse was on the board since I have read about other 49 port Block Erupter hubs having 50 or 70A fuses.  Does it seem likely that I can run a few higher-power usb devices like 2PAC or Moonlanders on this board?

Thanks for any advise or pointers to better threads.

I have no problems with eBay, I just couldn't find any for sale.  If you want to post a link then let me know.  If you figure out why ebay summons insane prices for equipment that can't ROI even with free electricity then post that answer as well. 

CreativeReef

I get it but for such a small amount BTC is more expensive and more hassle than PayPal.

CreativeReef

Just one is fine for my purposes.  If you accept Paypal then then let me know what shipping is to 25560 and I can send you the money.

CreativeReef

It is pretty small compared to my Baikal miners so $30+shipping?  It is hard to assign a fair price to devices like this and eBay is no help with price becoming insane for no real reason.

Coinbase says 3-5 business days so it will be next week.  Just keeping you in the loop.

@kramble already has a Blakecoin port to the Cairnsmore.  Check the OP for the link to Blakecoin FPGA miner.  Most of the FPGA equipment that I have is cast-off ewaste or repurposed consumer hardware and it takes longer to port the FPGA miner to.

CreativeReef

I tried sending you a PM but your settings seem to be blocking me.  I have no problem with using OgNasty as an escrow and as soon as my deposit clears with Coinbase then I will set up the escrow.

CreativeReef

There are some coins like Blakecoin using blake256r8 that can still be mined by FPGA pretty well.  Yes, baikal has a Giant-B that will mine blake256r8 but those are pretty pricey and they will do other more profitable coins as well.  As some of the memory-hard algo keep forking, FPGA can sometimes still be viable with some work.

Yes, I am on the lookout for FPGA miners working or not.

CreativeReef

If you accept Paypal then we don't have do escrow or we can if that is preferable to you.

CreativeReef

The Electrum port is pretty interesting and I hope that your work bears fruit there! 

As always, Thanks for your efforts!

CreativeReef

I don't think that any of the PinIdea equipment used FPGA but I could be wrong.  As far as I know, all of their equipment was ASIC based and if you still have a DU-1 then I would be interested in PM you about that.

@cryptodjee the OP was looking for FPGA miners and @cableiso mentioned that he had a box of failed miners that never worked for some reason and several of us were interested in seeing if he would sell some of those boards.  I don't know if he has gotten a chance to look at them anymore.

CreativeReef

I would be interested in several boards in either single FPGA or dual FPGA configuration if they are working and a reasonable price.  Did you decide what you wanted per board?

Thanks

CreativeReef

Would you accept $75.00 + shipping for the usb hub?  It is only usb 2 but it still might be useful for a couple of 2pac miners.

Thanks for your consideration.

CreativeReef

Thanks, I probably will just stick to what works but I was trying to save some money.

I have some older nvidia cards that I thought that I needed cudaminer for since ccminer didn't support the Compute Capacity (CC) 1.x cards that I was using but the latest versions of nvidia drivers support OpenCL.  I was able to compile cgminer for my nvidia cards under linux using OpenCl and actually outperformed my cudaminer install by 3x-5x.

This link from the OP works pretty well.  https://bitcointalk.org/index.php?topic=306894.msg6764336#msg6764336 and the only other thing that I needed to do was look at the section of this link called "mining coins with cgminer" to help with compling nvidia OpenCL support for cgminer

EDIT I had the wrong URL for the "mining coins with cgminer" link.  This is the correct link, basically you are pointing the cgminer include path to where the nvidia OpenCL include files are at.

I try to leave it open unless its getting attacked!

Edit:
just checked

at1 should have getwork open which is probs best for testing due to lower diff

Thanks, I still have some issues to work out but I was using at1 anyway.

Thanks, I was thinking that you had getwork disabled on your pools since it wasn't being used and bad actors were trying to use it an attack vector.  I will will retry my code again port 8338 and see what happens.
