bitfury detect (38:2) failed to initialise incorrect device? Huh

using macbook any help???

that usually happens if:
1. driver is not installed
2. not enough power per port

What hub are you using?

@goodney

Do you have new Stickminers in planning?

None of the current chips seem to be worth producing a StickMiner. They all use too much power for a useful hash rate. The closest I got was this BE200 based prototype @8GH/s. But it got way too hot, even with a huge heat sink.

If anyone knows of a chip coming soon that might be good for a stick miner, let me know!

These bad boys are good:

They are using the 2 x BM1384 chip for a solid 15+GH

This one looks good as well

A new generation of chips where released Wink

Get me samples and I'll knock out a StickMiner. Assuming the protocol is similar to the BE200 it wouldn't even take that long ;-)

hi goodney mind telling us how many of the bfx2 stick miner you made ? hundreds ? thousands ?
not mean to mind in your business simply curious for the history of bitcoin mining.

Are there any news about a new Miner?

Or has anyone BFx2 Bitfurys to sell?

Bitcoin FTW!

How hot is the BE200 miner with a fan?
If it could cool down with a fan, it might be a possibility..

Interesting to see if some of the newer sptech or bitmaintech chips could be converted to Stick miners just so that people looking to learn about bitcoin mining have a cheap way to get involved. Asicminer newer chips possible as well. Can you get them in quantity to make a small run viable for the builder?

Mind you Bitfury is not going to give up their chips or miners to people playing around anymore those days are done given their in house development and move to a B2B model. They don't need the community anymore I guess.

Question is whether it would actually work as one - your BE200-based one was nipped in the bud by the fact that the chip just runs way too hot in a typical StickMiner configuration. I do hope the BE300 and others will prove to be more fit for the purpose.. my post is getting stale Wink

CCNA: There i fixed the internet.

They showed data in the OP photos [email protected] but unknown ghash rate. Also he stated that it will me marginally more efficient in a "string" mode where the power chain starts at say 12V into "first" chip and ground for first chip is fed into Vcore of second, repeat until a chips GND output is ~0V

This how the bitfury strings worked and I'm assuming that they'll work similarly here(based off of pinout)

OK THX for your answer Wink

BITMAIN doesn't sell your chips BM1382 only?

greets

As far as I know the BM1382 isn't available to 3rd party developers. It would also have to be underclocked/undervoltage to work on a stick. Probably 12 GH/s.

If BM1382's are available for 3rd party development, I'd be interested to know that.

Even if they are, the real problem is the rest of the BOM cost...

I've got a worst problem:
2 of my 3 BFx2 are aside until I solve my problems with my hubs.
The one I'm plugging them, somehow doesen't deliver it's 3,5A to the ports.
When I plug one other, the further from the usb cable doesn't light the vcore led.
If I unplug the one with vcore's led lit, the other one light's the led and start's mining.
On other hub I get "unrecognized device", although Antminers, BE's and pen drives work on it. (although somehow i can't have more than 4 antminers for now, even with 10A... something weird over here...)

Are you sure it is really 10Amp?

You''re right. It's 30A.
It's a 350w ATX PSU.

30A on the 5V rail ?

You can use one of those 19 port high power usb hubs?
