Topic: [CLOSED] Block Erupter USB @ 0.20 BTC + parcel -> Shipping to anywhere! - page 21. (Read 54775 times)

Since the remaining buyers are not showing interest to pay as soon as possible their pending pre-orders, I am going to receive pre-orders requests from people interested to participate in the group buy. However I will only include the pre-order in the Trader's Book if the interested buyer is ready to pay. I want to close 50 units before receive the first batch to order another batch.

There is still 28 or more units available for the second batch. To place a pre-order for the remaining units, fill this form:

I suppose I only have 3 days to think what to tell the missus about how much I spent...

DHL. They shipped my Blade from Shenzhen to Geneva in less than 3 days, it shouldn't be any longer to London.

Which delivery service is that?

Great news A+C!

The first batch was dispatch!

Looking good! I bought several cheap 10 ports USB 2 hubs for less than 10 usd a piece. With external power providing 500mAh each port.
I'll go for this if I experience problems with my "cheap" hubs. But hopefully I don't need to 

Not really liking the buyer reviews on this one.  I think I'm going to go with this one.

What about the one they used in the USB Erupter pictures? The blue 10 port powered hub, some come with 2A adapters which is no good for anything over 3-4 but some apparently come with 4A/5A adapters.

Sorry for the late reply, 5 posts etc...

Anyway, from what I have seen, these hubs usually come with a 500ma or 1000ma PSU (have a look on the box before you buy it).  As you may know, each Erupter uses 500ma.  I would put in some extra capability so the PSU runs a bit cooler.  I have ordered 2 of these www.ebay.co.uk/itm/280840301713 that come with a 1000ma supply, and an additional 4A supply for one of them to handle the RPi (700ma) and most of the Erupters.

If you want to run more on one or 2 Erupters on a hub, you can add a different PSU. Hopefully the circuit board will handle the 4A PSU.  E.g. I have a 4 way port (probably from poundland) that came with my RPi kit, and it has the thinnest wires you ever saw soldered from the USB in onto the PCB inside.  These will probably not take 4A.  If the power comes in through a jack socket on your hub, it should be OK as it is soldered directly onto the board.

Another thing I am doing is butchering either the hub or cable to stop the 5V going between hubs and the host.  This will avoid PSU load balancing problems.

The best thing to buy would be a USB 3 hub, but the ones I have seen only have 2 high power ports, and are arranged so the Erupters won't fit next to each other.  There is an industrial StarTech USB 3 with 7 high power ports, but these are over £50. https://www.google.co.uk/search?q=startech+industrial+usb#q=startech+industrial+usb&safe=off&source=lnms&tbm=shop&sa=X&ei=P6ClUavmGcO-0QXK5oCwCw&ved=0CAwQ_AUoAw&bav=on.2,or.r_cp.r_qf.&bvm=bv.47008514,d.d2k&fp=76da77ddf20e87cf&biw=1494&bih=724

Wasn't cgminer upgraded and now you need to use it a bit different?

I've posted a short desciption in my GB to get them hashing...:

Not yet. I am waiting to receive a confirmation of dispatch and the tracking number of the parcel.


I will prepare a Internet page to provide support for the Block Erupter USB users.

and posts thereafter

Are these things going to come with a guide for n00bs (or can someone point me in the right direction)?

Any update on shipping from friedcat/asicminer?

If there are any units left that haven't been paid for I can pay right away

Please let me know!

Batch 2. Any idea when it will be ready to send out? Or we are going to see TM again? I'm asking since you will most certainly have units left that are not paid and you now accept paypal. I would be interested in another unit paid in part with paypal part in BTC. And if this will happen let say in 5 days I will probably have enough BTC mined and enough on paypal to pay for it.

The partial paid orders are part of the first batch.


Yes.

how do you think this usb hub powerful enough?
