There's no drilling to be done in the PCB, there's holes pre-drilled and pre-finished in the PCB itself, so you'd only need to align some markings on the heat sink and drill through the heat sink itself.

Then we could add some pressure to the connection with some bolts etc. (making sure of course that the thread on the bolt has a diameter smaller than the hole in the board)

I've actually found the top of the chips get very hot as well so have been considering fashioning some kind of double sided heat sink either with an external clamp around the sides (so the sinks sandwich the board) or a second sink with another drilled set of holes in it.

There is however a transistor that sits in the 4*4 chip grid that sits higher than the other chips, so some consideration for that would need to be taken into account before a secondary heat sink was applied.

As a side note - regarding the separation issues I've noticed that the issue is likely from a lack of cleaning of the PCB from the factory before the heat sink was applied (I'm assuming the manufacturers did the heat sinking too) there was a fine black dust between the heat transfer pad and the PCB which was found after a heat sink came off and I cleaned the board with some alcohol.

Oh yeah, it was not being able to package multiple transactions at a time? My mistake, I'd forgotten that part.

Oh and not sure on the 'bug' claimed in Armoury preventing him from sending coins without confirming the previous transaction.

If you're sending them from a single wallet and there's a large amount of coins in your wallet it's your change coming back to you from the network, not a bug in armoury, because as far as the network is concerned you've got 0 until it hands you change after the confirmations are completed.

Or I'm completely wrong, and you do really have a bug that happens to be mimicking that behaviour, in which case - my bad.

Apart from the obvious and severe lack of communication (As someone said, would it have killed someone to send out an email to the GB user list? We all know you've got it) because having to check back here to find out the reason I haven't seen a share payout was because the entire thing's been delayed by months.

I (and I assume anyone else actually aware of the issues and staying in the GB) would like to know:

Other than the 25% boost to hash rate we'll be granted by remaining in the group buy (assuming you're still passing that on) will anyone staying in the group buy be entitled to the additional 10% discount on all BlackArrow based hardware group buys run by DZMC in the future (until the offered period expires, so 2015)?

Another issue with the 25% boost to hash rate - BA doesn't seem to realise that it's not really a fix, it's obviously just covering their arses because if it was 25% additional hardware it might actually be worth it because then the GB will still have the resale option at the end of the life of the miner (for BTC mining anyway).

25% additional mining with their 'hosting' doesn't really cover a thing, as... oh wait that's right, a month after they were due that 25% will be worthless, (based on the fact that difficulty rises have slowed) and by the time they're received we'll probably be down to 50% or less BTC output.

A second thought with the 10% discounted hardware - will that include the existing order eg. covered under the price protection that was apparently offered? (Unless I've mistakenly mixed up two threads I was reading regarding hardware)

As an aside: As previously stated Matt (Bobsag) being a reseller and running all the purchases through himself to BA causes a major conflict of interest without complete transparency (I understand it's the only way it could be done, but the TRANSPARENCY is the key word), previous requests for costs/sales have gone unanswered so for all we know there's money being taken off the top as well during this entire thing.
(And before ANYONE says 'oh but it was at-cost' I've seen plenty of people state 'at cost' but that's at the cost TO THEM, which they can fudge the numbers on any way they see fit, whether it be labour, time, expertise etc, not just the sale price of the hardware + shipping)
We're also unaware as to how the BTC was moved, as it may have been cashed out at some point at a higher USD value, then cashed back in now in order to refund people (Which could either cause a massive bonus or a massive loss depending on value changes) so for all we know there's additional funds being skimmed off the top again without the end user really being aware.

The way you run a proper co-op is to have the group run it, to have transparency, to allow people access to information. While I understand we didn't vote for you to be our leaders, you're there and doing it because you can, you want to etc, we all (generally) benefit from that while I repeatedly see the people running it stating they end up at a loss at some points (That is NO way to operate, because if your operators start making losses it adds a certain underlying level of contempt to their userbase for 'costing' them something)

The fact that your website's been drastically altered and no updates have been provided also shows a severe lack of professionalism on the entire part of the co-op operators.

On a different note: While people investigating each other to keep them honest is all nice and useful to the end user... who gives a flying fuck if the guy smokes or grows or deals in pot? Provided it doesn't interfere with what he/she/it does here it shouldn't damn well matter.

If you've got that much of an issue with people being 'seedy' and 'underworld' and operating in BTC... get a grip on reality, it happens everywhere. Your next door neighbour could be a drug kingpin for all you know, but it you don't have any idea on that because they don't let it affect how they interact with you.

Can we also get some clarification in the opening post regarding policies, timelines (aimed, since nobody can really do 'fixed') and what will happen if the group buy isn't completed, if you've been vetted (I've searched around the forums and seen you've got a lot of activity across multiple sub forums and assisting people and so on but might be nice for people to know easily) and anything else you feel might be useful to getting someone to commit.

Thanks,

Hi there,

I'd like to grab 10, though would like to confirm if it's actually .08 or .07 (main body says .08, title says .07).

Either way, what are the transaction details and how do you want our shipping addresses?

^--- Whoooooa nice

Order #1162 - 3 shares
TX id: f254d2978d29ac94a2cadac895d8608f7580b314890535f985b6e4bd43cc7cff
Payout address in notes

Yeah, I assumed that they were putting all their efforts into repairing the issues at hand.

I also thought it'd still be nice to remind them people still want their gear, including new gear in the future

So just had a thought - I haven't seen anything about accepting returns but is anyone trying to return their boards, and will there be refurbs available?

Otherwise just wondering if anyones already looking to sell their boards .

Also for the DrillBit team: are the issues that are being dealt with causing any major delays in your thoughts/plans for another round? Just hankering to get some more hardware from you guys already.

The CGMiner zombie thing requiring a full reboot of your system applies to the thumbs too as well as BES hardware.
With the Drillbit Thumbs running I occasionally leave the house to come back to find exactly 50% (1/2) of both my Thumbs and BES' have zombie'd and require a reboot.

This is on Windows, I haven't managed to test them for a long period on MinePeon or anything like that yet, so I expect it to be more a USB/driver issue than hardware fault (Though I'm neither a hardware or software engineer, thats just how it seems to me with the reboot fixing it, power cycling /replugging the devices doesn't so its definitely my PC thats effected by it)

Thus the mention that if his wallet address etc can be verified. More effort than its worth for outsiders to randomly look for unless someones bored but still a significant loss if it's verified

You might want to include (at least until its found (if its found)) and if we can find the guys wallet address
James Howells Loss (lost wallet) 7500BTC lost.
Believes his wallet is currently sitting on a hard drive in a British land fill and is trying to search for it.

I'm interested in a couple depending on the price as well - though I'm also in AU so would need to work out the shipping for that one.

I know there aren't any left at present but on the off chance someone fails to pay is the price still the price stated in the first post of the thread? (upward of 4BTC, so like $4000USD+?)

Thanks

*sigh* Thanks for that, I wasn't entirely sure who the SwishBits person was in the forums, so now I know.

Thanks again, and hey if you're one of those Aussie people and you're in the know on any buys you could point me at them ;P

Just wondering if SwishBits is still the Australian reseller as I've been unable to get a response for queries for at least a week.

The shipping to bobsag would be in bulk, so he should receive everyones orders in (several) big boxes all at once and then has to break them down into your individual orders to post them. So your express post would be from bobsag to you.

Unless it was for a thumb, then it'd be express directly from Barntech to you.

Technically provided the voltages are the exact same you can run an alternate power source. The primary issue is the amperage. If you actually draw more amps through the new power source than the device can handle (eg, the circuitry and wiring) you can cause the USB hub to overheat, die, and potentially (in worst case) catch fire from the overheating.

The quality of the hub will also likely dictate how high the amperage can go as a low quality hub is likely to use low-end materials and poor quality solder work on the contacts, potentially causing additional issues.

(As an example I bought a couple 7 port hubs only to find that it was actually two hubs cascaded (eg 1 hub connected to another internally) which caused the second hub to fail entirely, as well as poor solder work, incomplete/missing contacts etc. Both of those are now junk as they don't function)

Was the fan you were using a USB fan plugged into the same hub (Assuming BES, not BEB) or otherwise on the same 'power circuit' internally? Could have been the power draw affecting the BE's ability to function under load (unless the fan was introducing electrical noise into the power lines for the BE's?)
