Hello

I am very pleased to inform you all that at this very moment the boards are all getting made. This is the last charge. I don't want to make any promises that i might then accidentally not be able to keep, but i'm pretty confident we'll be shipping next week.

We are going with the 12V version, so feel free to go out and get power supplies. Also, i don't know if I've mentioned this before but each miniplane and each double scroll has a connector for a fan, so with a full 8 board setup you will have connections for 3 fans. I think i'm gonna go with these http://www.newegg.com/Product/Product.aspx?Item=N82E16835103090 but haven't decided yet.

IAS, i know what you mean about the size of the boards, much smaller than you expect huh? The fully stacked miniplane will be a neat little cube.

Onto boring admin stuff, i still haven't received shipping payments from quite a few people. Can everyone please check their names and sort it out. If i have accidentally missed you, apologies in advance, send me a message.

Hello

To whoever ends up winning these chips, if you are looking for something to do with them, drop me a line. We have one chip thumb, and 8 chip expandable board designs ready to go

Cheers

Barntech

Yes!

This is all running on a rasp pi by the way for all you pi heads.

On other news, I just visited one of our mad scientists in his lab. The photos speak for themselves. 







This board only has 7 chips on (for reasons not worth going into), which means we're currently getting 2.24 per chip on the 8 board. Not bad. This is without proper cooling and various other tweaking on clock, voltage etc still to come, so we're looking good. 

Ok. Sorry for the confusion. It is this connector. Pretty sure they are standard with most power supplies.

http://pcsupport.about.com/od/insidethepc/a/atx-pinout-6-pin-12v-psu.htm

IAS, i believe the 6 + 2 you were talking about is just one of these; can be 6 or 8 by just including the 2 or not:

Basically you will plug it in and it will take the power that it needs.

Hey,

So if we go for the 12v, the connectors on the boards will remain 4 pin molex, but the connectors on the miniplanes and doubles scrolls will change to 6 pin molex. On the miniplane, probably only one will be required, but we may put 2 on just to make sure you'll get enough power. The double scroll will have 2 for sure. This means for all you ex GPU mine heads, your giant PSU will potentially be able to run four double scrolls.

Here's a picture of the 6 pin molex connector.



And just for the sake of it, here is a picture of my old GPU rig. R.I.P .... Soon to rise again Drillbit styley! 

Hello.

I'm back. Thank you everyone for the heatsink payments. Nice to see that happening. Much appreciated.

Progress report on the 8 board is this: All the chips are working at nice speeds individually. Still ironing out the code to get them all running at full speed together. It's happening, our guys are on it. The 12v proto board is built and we will be testing tomorrow morning. Once we have verified that it is working, we will be all set to send the 8 boards to manufacture, almost definitely the 12v version, unless there is something wrong with it, which is very unlikely. We should be getting the boards back ready to send out by the end of the week.

The thumbs will also be going out this week.  

Paypal address is jessericketson@gmail.com  Send heatsink paytments there, or to the BTC address.

Thanks to everyone who has chucked in for heatsinks so far. Going well. 

And yes that image correctly depicts the standoffs. Will be much sturdier.

I'll be out of contact for the next 36 hours or so. Have a nice day and a bit in the meantime.

Hey guys.

A few notes on heatsinks. Basically, heatsinks are good for your boards. They will lessen the strain on the chips and extend the life of the boards. If you are planning to run the boards conservatively without too much overclocking, then they will not get too hot and fans may well do the trick, but even then having heatsinks will be better than not havijng heatsinks. If you plan to overclock the shit out of your boards, then you will definitely need heatsink. Once they are cranked right up they get HOT, regardless of what climate you're in. The reason the BFSB boards didn't need heatsinks is because they were running each chip at 1.6 GH/s, very low power draw and heat at that level.

Soooo, we have made they executive decision to ship heatsinks as standard with all boards. For every board you have purchased you will receive one heatsink with thermal tape on it to adhere yourself. If you have already organised heatsinks or don't want to use them, then you can just leave them off. They are sized to make sure the boards with heatsink attached will still fit the miniplane

Now, these aren't free, they are costing us a reasonable chunk of money, but basically we don't have time to chase 100s of payments at this point. If i had more time i would be taking payments from people who want them and only shipping them to those people, but there isn't time for that. So, consider this a social experiment of sorts. It would great to get payments for the heatsinks. If you would have payed for them anyway, and know that you want them and are happy to be receiving them, please pay. If you wouldn't have ordered them, and don't really want them, then don't worry about it and enjoy your free heatsinks.  Lets see if an honor system can work in this crazy scenario. I believe it can. Prove me right!

I managed to get a whole bunch at bulk cheap rates so the price for those is $5 or 0.03 BTC each. Bargain! Please send BTC to 1AF1WmU9Ut2CMuMJWgeBiXb2LMCd6x1GYA. USD to jessericketson@gmail.com.

Let's see if this works.

Also, everyone who is getting a miniplane will receive stand off spacers and little plastic screws so you can lock the whole thing together and make it nice and rigid! Cool huh? 

The heatsinks will be these:



The spacers look like this:

Alright. Heatsinks.

In the end, these are the ones we're getting for the thumbs. All the thumbs will come with these.



As for the 8 boards, considering a few options. One is two have two of these guys on the back like so. These are pretty great but they are quite expensive, will come in at $17 for the pair.



Another pretty good looking option is these guys. Will be cheaper and probably pretty good, though we don't know thermal details. This will be $10



Let me know your thoughts on these. We will need to order them very soon. Will probably be easier if we just get a bunch of the same ones, so perhaps the cheaper ones will be more universally appealing, though i guess two options is an option. Can i get a show or hands?

Cheers

Hello Cryptx.

I have written to you several times now through your website contact form and have received no response. It is upsetting to be so thoroughly ignored. I placed an order on your website on the 1st of October. here are the details.

Order #1274 made on October 1, 2013. Order status: processing.

I am writing here to formally request a refund for this purchase. I have not received anything from you, the customer service is horrible, and it is very clear that your boards do not perform anywhere near what was promised. I paid you via bitcoin. The amount was 8.1593. Transaction 6d5bc997a60437ec33d689309f34fd7f1b6c6d8e2f7cf87ad4c3a66904045d9b

Please do the right thing here and refund my coins, or at the very least make contact with me so we can discuss things.

Regards

Barntech

*** Update - Refund received. Thanks for being good about it Cryptx!

Yeah crazy spam town. I've changed the setting so that new registrations require admin approval and made Lajz99 an admin to help keep things smooth over there. Should be sorted now.

Yes. As soon as stuff is ready we will ship it out. If this results in needing to send things as two packages we will do it and bare the additional postage expense. We want to get these things to you as fast as we possibly can.

On other news, we have changed the heatsink on the thumb to a better one. These are going to cost us a bit more, but its worth it for the added heat dissipation. These should ensure that running the thumbs at 2.7GH/s will be sustainable and potentially work without fans (though i'd still recommend fans). Now these are costing us about $5 each but we're not going to charge any extra. If you feel excited and oozing with warm fuzzy feelings, by all means chuck us some donations at 1AF1WmU9Ut2CMuMJWgeBiXb2LMCd6x1GYA, but no obligation there. Will very shortly be publishing our recommended heatsink for the 8 board. This one will cost more and fall outside of our loving philanthropy thresh-hold, so additional payment will be required for those, but if you're keen, we will buy a bunch and ship them with the units. 

Barntech

  Very excited to put your package in the mail lazj99! That day will be quite a milestone. I'll see what i can do about a pretty pink bow and perhaps another special surprise for you.

General step from here is complete the testing on the 8 chip board to make sure its ok. It almost definitely is, but we want to be 100% before we go making 100s of them. The thumb is already verified and ready to go. From there its manufacturing the PCBs, assembling them, and shipping out. 

Hey hey.

So yes, still some bugs to to sort out but we're damn close. Striving to sort out those duplicates now.  The 8 board is getting there too, also still needs more tweaking, but its happening.

Someone mentioned chips, yes we have one batch and the other is due to arrive tomorrow. 

As for Cgminer. We will be having our revisions rolled into an official update of Cgminer, so the 'latest version' by the time you get your hands on these will just work straight out of the box.

So close.

Barntech

We have also decided to provide heatsinks as standard with the thumbs. 

Speaking of cool. This! 

OK Erk you got me. Basically whatever will make people happy. The Drillbitsystem forum is there for whatever people want to use it for, and any discussion here are also welcome. As long as we're all having a good time!

Bahaha This makes me wish there was a "like" button on this forum!

... No offense Erk.

But yeah i do think gh/w is a worthy discussion topic. I haven't got good answer for you yet on that unfortunately, but as soon as i do i'll share them with you all, but basically the theoretical maximums already discussed shouldn't be too far off, somewhere in the vicinity of 1W per GH.

And regarding the hashrates, yes th ahrdware is built to achieve the hashrates stated in the title of the thread. From here it is software tweaking, overclocking etc to get it up to those rates.

More soon.
