Topic: [Work in progess] Burnins Avalon Chip to mining board service - page 125. (Read 624197 times)

Burnin, do all the board's chips share the same 32-bit nonce range? How often can work be restarted?

However - as my opinion whether you are recommended to buy or not buy - I don't know your regulations there and suppose they're quite strict, like FCC stuff and EMC tests. Until for example proper measurements of equipment are done - it may be risky to install many of these near yourself due to electromagnetic emission and noise. So either properly designer board and/or filters and/or shielding is required. I hope that this would be clarified soon. This is also true for homebrew devices that you make and don't care about switching noise such devices produce (like I saw in some DIY stuff where powering of such high-power chips are done in absolutely insane ways, or like problems with other asic vendors, you know them by the way likely, where their shipments were banned by customs due to these violations).

Anyway, as far as I know Dave has as well options to install miners in his location - this would be likely safe in any way, and maybe if you install these - before proper measurements done (i.e. in special laboratory with antennas where typically EMC measurements are done) - this maybe risky to install at home,  or at least close to you - so don't sit near miner 24x7 and don't put those close to you.

You should care about that and do not put your health into unnecessary risk. However I suppose Dave will do his best to solve these issues and make device fully compliant for safe usage. However that still won't mean that such equipment can be installed in bulk at home, and should be spreaded in space for maintaining safely low electromagnetic noise. Likely also undervolted boards is nice choice for safety, but all of that should be measured, and likely will be measured, the only delay could be there (and it is basically your choice) that such measurements could take additional time and can't be done before August timeframe. This depends.

payment for assembly only in
BTC
or
USD
or
€
or all of them?

Burnin told me via pm that he will do it in priority payment for assembly and second priority the chips he has in hands. A early payment without chips in his hands cant be fulfilled first.

Burnin, just a question on ordering.

for example: if the chips-order Batch1-5 from sebastianju arrive at the same time... do you work down first batch1, then batch2, ... or do you work down on order date on your page?

This is an open-source project, the sources will be released when the product ships.

Fantastic result burnin, congratulations! I guess this journey is nearly over for you now. I imagine it's going to be a pretty great feeling to see the first few hundred boards coming off the production line .

Overall status:
Wrapping up the last few changes to get these boards mass produced.

cgminer screenshot for a long run at 320Mhz - 6.4Ghash/s, about 0.12% HW errors.
The reported temperature is the actual board temperature, chip surface measured ~50°C.

Isn't this whole thread proof enough when it comes to my abilities to develop and build products that actually work?

Next week.

I don't need schematics to create a bitfury mining board.
All the infos needed to adapt the bitburner to bitfury's chips were already released.
(Pinout and protocol)
Once the Avalon stuff is all done i'll do a Board with those chips.

Anyone know if there is electrical insulation (thermal interface material) between the heat sink and the board?

Burnin - ETA on website + ordering?

I don't think punin will give the master board schematics after reading from here: http://www.bitfurystrikesback.com/product/bitfury-55nm-asic-h-board/  "16 chip Hashing Board to be used with the Master board (or separately if you’re a real hacker)"

Are you a real hacker burnin? Will you offer mining board service with Bitfury's chips? If yes how are you going to get the schematics of the boards?
