I put in a refund request today on the website, will update and let everyone know how that goes. (Ordered 1 25gh/s kit + 7 h-boards for ~49 btc.)

Can I inquire why you would want a refund?

My guess is that he doesn't believe that 200GH received at the end of October will return 49btc in its useful life.

My calculations are very rough, but I get 54 total BTC... so a very slight profit but risky. If BTC price can get up a bit higher, I am interested in the october delivery, but with current prices, the risk/reward just isn't there for me yet.

My calculations may be ridiculous though as I am forecasting 130M on Nov. 1st.

I think an upper edge slot brace is a good idea. These are hand made prototypes, so Cscape used the caps he had on hand - I know he recommended a larger cap along the way too, so perhaps you are seeing the newer assembled boards vs the boards he made a couple weeks ago.

There was a mismatch between the capacitor shape on the board, and the capacitor mentioned in the parts list. I ordered the (smaller) caps on the BOM, but noticed it didn't really fit well on the footprint on the board. I put the small ones on anyway (with hand soldering it is just possible to do that), but ordered the bigger ones for a better fit, and used those on later boards.

Electrically they both work, so there was no need to replace the smaller ones on the first couple of boards.

thanks for the response, I wasnt sure if i was seeing things or if there were just different versions of board in there.

there is a decent amount of PCB space between boards. Is there a reason for that, or will version 2 boards be designed more densely in order to shrink the size?

EDIT:
Received the proper refund in btc on the next buisness day after submitting. (Lost 1.2 btc in the exchange rate, but thats just life

)

+1 for their refund policy.

That looks awesome, already been working to fund one of these myself

By the way, this project would go nicely with Bitfury rigs for standard ATX power that takes care of both the boards and the Pi:

https://bitcointalk.org/index.php?topic=263567.new#new

I know this is still in a prototype stage, but are there any specs available as far as the physical aspects (Size, mounting holes, etc)? Like many I'm sure, I am wanting to start mapping out some kind of mounting system/case.

2) Per the website:
- 25 GH = 16 chips & 400 GH = 16*16 = 256 chips -> they both average ~1.5GH per chip.
- But the chip page states 2.7 GH per chip.

Does that mean the 25 GH full kit's real hashrate is ~43GH(2.7 * 16), and the 400GH is ~691 GH(2.7 * 256)?

3) Are the inventory numbers for the Oct fullkits accurate? right now it shows a 378 unit left for the 400GH, if all 378 gets sold will they all be delivered in Oct?

Thanks, i like how this is not dependent on avalon and already has asic chips in hand.

buzzdave, can you please answer the above questions, i am thinking of placing an order for the oct 400gh unit after the july shipment was confirmed, but like to have the above answered. Thanks

#2 chips are capable of over 3Gh/s under highly controlled conditions, but our boards are underclocked in order to avoid issues described many times in this thread.

I'm making no promises here, but Tytus is seeing peaks of 130+ Gh/s from his 4 card rig. This could be just a phenomenon of pool stats. I see 101 Gh/s at this time. He's sending to Slush, so I can't provide a link to the stats

#3 I took a stab at inventory numbers for October. I don't know yet how many we will be able to offer, but I'm confident we can provide what I sell. If we have more available, I'll adjust quantity as we get closer to October.

these for Boards for Aug. delivery?

Hboard is underclock for no heatsink.

This is a prototype rig, hand assembled. The design is for the 100TH project which is *just* starting to mine - most of the hardware for that is still in China.

August delivery boards will have some minor changes as noted - rPi connector, power plugs

spectacular! I can see why it was said that these need some sort of stand-offs to prevent breaking/wobbling if in the direction of a fan perhaps V2 boards could have some mounts at the top the run spacers between and fortify the boards against oneanother?

also, is it just my eye or the camera angle, but it seems that the capacitor on bords 7,8,&9 look slightly different in size? On boards 9 and A, the capacitor looks big and fat, but on the boards 7,8 it seems much smaller for some reason?

Thanks to Cscape for hand-assembling these boards! This is long, neck-wrenching work to do all this by hand!

As you can see, the prototype rPi connector was not the right one, so it oriented the rPi in a weird way. We've since identified a taller right-angle connector that puts the rPi vertical like the other H-boards, as originally designed. We are also replacing the power connector with Molex-Jr to match your PSU power supply GPU plugs. These are 100TH boards, which don't use PSU power supplies.

Case designers: don't forget you can have a small display from the rPi. It would be great to see someone figure a way to drive external LED's from the rPi, despite that we tie up all the GPIO pins.

This is what 400Gh/s looks like.

Dave that's just beautiful. Thanks for posting the pics.

Would love to see some stats of it actually hashing.

After tomorrow, we may have an outage, yes. They are working with me, and I may have to ask for a couple extra days. If the CC processing begins to fail, you can hold your spot by choosing Bank Transfer payment, and note that CC processing failed. Kat will catch up to you later for payment via CC.

Dave,

Are you telling me that at this moment, today, tomorrow, my CC may not go through if I wanted to order 4 more H-boards?

Regards,

Just say that you want to pay via Wire Transfer, then in the notes indicate bitcoin and you will get a bit pay invoice (they do it manually)

Yes, i've made orders that way already. I was asking about integration with the web site so that they don't need to do it manually.

BitPay's helpfulness has declined since their initial attempts. The system is working pretty decent now - with BitPay integration I found that I had a lot of non-paid BTC orders clogging up the system.

Meanwhile, I must find a new CC processor. Current one can't handle our heat Tongue

Is Stripe trying to distance themselves from BTC?

I can't speak for them, but they are worried about these kinds of projects - same as Kickstarter projects. I've informed them that we are actually shipping our July delivery product, but it doesn't seem to matter. I also offered to let them hold customer money in its entirety until we ship, but that didn't help.
