Title: 2x BFL Single FPGA
Post by: Valle on July 17, 2013, 03:44:28 AM
I'm selling two BFL Single FPGA for 6 BTC (3 BTC each), shipping to US from California (sf bay).
1660 mh/s averaged on heat-resistant firmware.

Just thought I'd comment that your price is very reasonable.  However, I'm spoiled by ASIC technology, so I'm not looking to buy more FPGA at the moment.

Any warranty ?

If BFL still had their trade-in program I would so buy these.

Have you thought about just selling them on ebay as FPGA dev boards? They don't have many I/O options but someone could find some use for them.

Looks like bfl trade-in program is closed, so bfl broke it's own promises once again :-( Yes, I've searched price of the fpga chip inside but it gives prices from 40$ to 4000$ - I don't think it is because everybody want to buy this.

Any warranty ?

These items works and has been working more than year with almost no issues. However small fans sounds suspicious, so it should be replaced in 3 or 6 months maximum. I don't think I can give a long warranty because of fans.

oh, one more thing - I run these devices with no cases because smaller fans scratched it from inside. It is very common issue. I'll assemble it back and check if it works fine before sending of course.

I believe 4 btc is not a great price. How escrow here works?

its not great but it's something and it's immediate. not many people are looking for fpga's anymore. basically once we agree to terms we pgp sign a message to John K who then I pay the 4BTC to as well as a 1.5% escrow fee.  He holds the money until i receive the goods and then he releases the funds from the escrow account to the address you specified in the contract.

It makes sense. Let's wait until tomorrow. I'm reading who's John K and how pgp/escrow works meanwhile.

4 BTC is a pretty good price so if I were you I'd take it. The new owner may not ever break even on this investment but who knows he could have other purposes for it? From my understanding BFL had firmware that allows it to do other stuff like medical imaging processing and other scientific number crunching.

I wondered why GPG is not very popular thing. After spending several hours to find a PGP not-console-only software what does not look like horrible shit and able to import my own certificate I use for ssh/github/android I've understood why...  :-[

Okay, aspeer, I think I should accept your 4BTC offer, but I hope you will guide all the process because I have no idea what to do next :-) Address is 1CVN4kDR26yK74LpHAHdgqAu67SWvyUA6c.

If this is not done and you can ship quickly, I will pay 2.5BTC for one (with USA shipping). If a sale is already underway, please disregard.
