It connects to stratum proxy running on a PC
using it's own TCP/IP stack. No OS, just on
the bare metal. It's c-scape's work.

intron

So its standalone

Not totally, it still needs a PC running a stratum proxy.
When there is time and the poor little ARM can handle
the workload it would be nice to have it truly stand-alone.

Code is running on the ARM Cortex M3, getting work from
the pool and sending results back using on-board Ethernet.

Just one quick question about your miner: is it running standalone (no underying OS, but using a lightweight TCP/IP stack) or hosted (by an OS like Linux, and if so, which OS)?

Thanks.

Nice... your fun project seems to be the pre-eminent Bitfury DIY project on the net currently.

Hopefully chips will be available for sale soon and you can enjoy the fun of profit as well.

That is pretty fantastic.... though at 2.15 GH/s the 120GH miner is going to need about 56 of those chips.
Are you going to try to push more power through it to see if you can get the desired 5GH/s speed (for 24 chips), or is that something that metabank themselves will need to be exploring?

We will play around a bit, see what we can get
out of this ASIC. But we have no set targets or
something. It's merely a fun project:)

Cool! But how can it estimate hash rate without any accepted shares?

Few minutes later:

intron_2 2,149.59 MH/s 174 (100.00%) 0 / 1 / 0

Sweet! ~~Looks like there's a rounding error in whatever mining pool you're using. With 174/1 accepted/stale shares it should only give a 99.43% accepted rate.~~

Pretty cool that it's working now though.

EDIT: I can see it doesn't count duplicate shares as stale.

So bitfury is making btc now:)

I'm just one of the alfa-testers. bitfury asked me to post
the progress I make, so that's what I'm doing here in this
thread. Looks like I'm still the only one doing so:)

intron

Bitfury took my address, however no chips were mailed. Shame, I bought a fair amount of thin 2oz FR4 for doing a four layer board as the supplier I found locally doesn't sell single ft^2.

I think that you can pick-up some chips from Dave or from Silverpike. And/or maybe wait till next shipment, as right now there's too few amounts of chips and quite difficult to send. Niko likely will send samples later, when more quantities will be available.

Ok, I'll send them a PM. Also check your messages, had some observations with regards to your decoupling posts.

Just to clarify; there is still enough chips on order or scheduled for delivery to cover both the 100TH and Metabank deliveries, right?

Fantastic news. So you are looking for mass production of low cost miners.

That's good for competition, and good for Bitcoin.

I like where this is heading.

I think that Bitfury have sent chips to you by posts they are not fast as couriers so it will take some time.
