3 Best Bitcoin Mining Hardware ASICs For 2019-2020 ...

What do you guys think about the idea of crowd-funding a simple, open-source, enthusiast bitcoin mining full node?

It seems there could be a need in the bitcoin market for a low cost, simple, open-source bitcoin mining full node that is aimed at bitcoin enthusiasts. Maybe this is something we can crowd-fund as a community.
Something like this could go quite a way to give users a bigger voice/vote in all this scaling controversy by making them miners as well. It would also make it easier for users to run full nodes.
It seems the closest thing to this product concept right now is the [21inc bitcoin computer]() but the price and complexity of the device makes it only really suitable for developers.
This would be my initial suggestion for the spec of the device;
Product Design
Electronics
Software
I have the ability to do the 3D design work for the project but we would need people to handle the electronics spec, schematic and layout. Also we would need people to create all the software. I have a very high quality and competitively priced PCB and PCB assembly supplier in China to get the electronics manufactured.
What do you guys think? Could we crowd-fund this with bitcoin? Would people be interested in buying these? At a very early estimate on the BOM, it would seem this could be done for under $100 if we get high enough order quantities.
EDIT: Rough BOM
  • Enclosure (probably 2 parts) = $10
  • Raspberry Pi = $25
  • Mining Chip Module = $?
  • PSU Module = $?
  • Wifi Dongle = $5
  • 128GB SD Card = $45

60 BTC tip for VHDL ASIC working design

Continued from http://www.reddit.com/Bitcoin/comments/1e5qim/reverse_engineering_of_avalon_asic_chip_work_in/
You guys convinced me that the best way to achieve the goals stated in the previous post is to design the ASIC chip from scratch, or based on a FPGA VHDL design, instead of reverse engineering it.
Here is a reference to a relevant FPGA design opensource resource :
https://github.com/fpgamineOpen-Source-FPGA-Bitcoin-Miner
And also the original FPGA which the Avalon ASIC is the evolution for, and for which there are schematics and documentation available at :
https://github.com/ngzhang/Icarus
So i'm offering a 100 BTC tip to anyone who can put out a VHDL Bitcoin miner working design conforming to the avalon specs at
https://github.com/BitSyncom/avalon-ref/
Thank you in advance for your response! This is an amazing community!
Cheers
EDIT Opensourcing the ASIC chip design is indeed something that will happen according to our roadmap and milestones reached. At any further revision of the chip the previous generation would be opensourced.
Added link to FPGA github resource mentioned in the comments.
Since i received several critics regarding the size of the tip/bounty, i have modified the amount a bit. Thank you!

Im buying a lot of 100 grade A BFL chips who wants to add to my order?

So as I am sure most of you know Josh from Butter Fly Labs just announced they will now be selling ASIC chips in bulk. However you can only buy a minimum of a 100 at a time. That lead me to start doing some math and I am going to give it a shot. So this is where you come in, being that I already met the minimum I am opening the door for anyone who wants to add to my exciting order. This is the important part! I will only be doing this once and not if I can’t be in the first round of ordering. So what does that mean for you? When you place your order know that if I do not get my order in the first day “to assure premium placement” I will not be ordering at all and you will get a full refund that day. Now on to pricing I’m asking 1 BTC per grade A chip and for that price that comes with schematics directly from BFL and USPS Priority flat rate shipping US only. I do not now when exactly they will go on sale but it will be in June. May be tomorrow may be end of the month so get while the getting is good. I’m sure you have a million questions https://forums.butterflylabs.com/announcements/3014-butterfly-labs-announces-bulk-chip-sales.html To place an order please privet message me with how unit(s) you would like and an email address you would like payment link to go to.
Edit:
I will fill in form after order is placed and BEFORE payment is made. After Payment Is made A notarized copy for you to keep and a copy to be notarized and returned will be sent to you to complete the agreement. The final version will have my name, office phone number, and an address to mail signed agreement.
Letter of intent This letter is to provide assurance of completion of agreement between _______________________ and ______________________. On this date ________ an agreement was made that ___ ButterFly Labs grade “A” Asic chip units where preordered for the price of 1 Bitcoin each totaling ___ Bitcoin(s). All pre orders are final unless the unlikely event of non-satisfactory placement in ordering position which will result in a 100% refund.

Who has orderd Black Arrow's X1 / X3 miner, and has not yet demanded a refund?

I'm still waiting for my refund, but I'd like to update all BA customers, that no way they will ship on May 1st, as they keep promissing: Bitcoin Miners progress update – 21 March 2014 1. Global Foundries have finished the test wafers which were subsequently shipped to Amkor. 2. Amkor and VeriSilicon decided to redesign the substrate. This should be finished by tomorrow but there is no confirmation at the moment if a slight delay of few days will incur. As it stands we might still be able to keep on track for the tight schedule. 3. 5 case factories fitted our strict criteria and succeeded in making our shortlist. We will decide shortly which one(s) will be able to meet our high quality demands and meeting our aggressive deadlines. Payment was already made to cover the required samples. 4. We produced a prototype case for X1 which was made of steel. We are not planning to replace the original design but we came up with this as plan B in case in case the plastic mould won’t be finished on time for Batch1. 5. We have received the 1600 Watt PSU from Power-One, will test this week. 6. We have tested the hashboard sample and other PCBs we've produces so far in a laboratory environment. Despite the lab samples are not meeting all our design requirements to 100% we are happy to report that all perform properly. We are currently negotiating with our suppliers to increase the quality checks for producing much better quality boards. 7. We have tested the (under-spec) X1 hashboard PCBs and it can deliver 130Amperes. We were targeting 140Amperes but the problem appears to be in the coil not in the PCB. We’re getting new coils tomorrow for further testing. As a reference, VeriSilicon’s projected consumption is 100 Amperes in worst case scenario (high leakage) but we want to make sure that we can overclock the chip. 8. Finishing the boards takes longer than we’ve expected. For this reason we’re not sure if we have time to finish the 200Amperes board. 9. We have corrected several schematics and layout issues in the X1 hashboard and X1 backplane and started manufacturing the new samples 10. Following case review we have added a fan connector to the X3 hashboard. We haven't taped out the X3 hashboard yet as we will have to be sure that the X1 hashboard performs properly. 11. The control board boots Linux partially. There are some drivers missing or misconfigured and we need to fix some bugs in schematics. We're now reworking it to change the main connector and fix schematics bugs. 12. X3 backplane has not yet been finished due to modification of the control board. 13. We’ve started work on our Bitcoin/Litecoin pool. 14. We got the BTC refund document back from our solicitors. We are updating few legal and we should be able to release this as early as tomorrow. 15. BTC/LTC and PPC payment processor is now online, ready to process orders. Still making some cosmetic adjustments. It took longer than we’ve anticipated but we’re happy how it works. 16. Front End for the LTC chip is now stable. We’re starting the back end as soon as possible and we’re going to start pre-orders soon. 17. We’re looking into providing schematics as reference design for our ASIC in order to gather more interest from 3rd party manufacturers.
