Topic: Home made bitcoin miner... - page 2. (Read 15412 times)

I'm supposed to meet up with my friend soon, as he is going to lend me his project/hardware. I'll take some pictures of these chips he has and send them to the few people that asked to see them who could possibly help. Hey, I can't lose here and neither can the person who would be able to help him out. He/she would get a free ASIC miner out of the deal AND paid for programming it. This all sits on the fence right now until I can confirm what really those chips are. I'm sure the chips will have some identifiable marks on them and I'll snap close up pictures of them. I know many people said it is impossible to get or buy ASIC chips for this purpose, but it is also hard for me to believe that someone could know EVERY possible manufacturer and way to get those chips. Hey, I'm hoping for the best and wish it true but if it is all the wrong hardware and just old FPGA chips then so be it. From the looks of it Butterfly won't deliver anything for a very long time and Avalon well, is just a one timer right now from what I've seen. I'll take. I'll let you guys know when I get the hardware.

Yup... i think my toaster has an asic inside

opentoe: true, your history is not suspicious. But there have been reports by forum moderators of random bitcointalk.org accounts getting hijacked (via password bruteforcing, etc) and used by scammers in any way to run their scams. Bottom line, I do not trust your (or your friend's) claims. Perhaps you simply misunderstood the technical details of what your friend is doing (eg. as others pointed out he may have FPGAs, not ASICs).


Obviously, "ASIC" in the context of this thread means a Bitcoin ASIC, not any ASIC such as GPUs, CPUs, etc.

Relax man... He is entitled to his opinion, that does not mean he is right, and it's certainly no reason to get all worked up about....

Send me a PM with a photo or parts list and I can tell you or your friend what is needed as regards programming.

I'm mining using an ASIC. Code name Juniper. It is an Application Specific Integrated Circuit manufactured at TMSC Taiwan using their 40nm process, and includes 1 GB of memory on it's custom-designed circuit board too.

Your friend is into electronics and doesn't know the difference between an ASIC and an FPGA. This is very obviously several FPGA chips he has. It sounds like he bought 20 FPGA chips and needs help programming them. He better hope they are Spartan-6 LX150 chips or he is going to be very disappointed with the hashrate. If they are, though, he should be able to achieve over 4GH/s. This means he better hurry to get them online before the hashrate jumps as larger companies roll out the ASICs they have been developing for months.

Anyway, I personally can't help him but I'm sure many on the forum can. FPGA mining has been around for a while.


For your friend's information, an ASIC is an application specific integrated circuit. It is build to do one thing. In other words, it is "programmed" in hardware and created already able to do what it needs to do. The advantages are low power and die size and they are often used in lower power applications or in markets where competition on power efficiency is important.
FPGAs are designed to be flexible. They can't do anything. They need to be programmed in order to be able to execute the code given to them properly. This wastes space and makes them inefficient.
Do not confuse general-purpose CPUs and GPUs as FPGAs. They are ASICs. They cannot be reprogrammed. This doesn't mean that they aren't designed to be able to do a broad amount of things.
That is the extent of my own knowledge. If you are actually interested, consult wikipedia or ask someone else.

Edit: @DeepCeleron: Don't be a smartass. Especially if you have nothing useful to add.
I've edited this post to say this instead of posting new because I don't want to interrupt the now back on topic later posts.

You accuse me of being con artist? Go read any of my previous posts, does ANY of them seem to be of a con artist or someone trying to scam anyone? Also, I never asked for anything. All I was going to do was forward my friends contact information to whoever could program the hardware. My friend is willing to pay for the programming and would give a free miner/unit to the programmer. How in the world could this ever be a con? What, some programmer is just going to work for nothing or something? Sorry bud, you are way off the mark here.

Why do you not let "your friend" come here to the forums to ask for help? It sounds like "your friend" is incredibly resourceful and lucky if he managed to get his hands on "ASIC chips", to design a PCB, and even has cosmetic details like the casing done, but yet he is incredibly bad at knowing where to reach for help (this community / forum) to finish the "programming"?

No company sells mining ASIC chips yet (maybe ASICminer in the future, but not today). I think you are a con artist who invented a ridiculous and implausible story to hope to attract developers and con them to pay to get a "development board" to "finish the programming" 

Ehh... I'm pretty sure your friend doesn't have what he thinks he has. ASIC chips need to be designed for Bitcoin mining, they need to be manufactured for it and can only be mass-produced in the hundreds of thousands, you can't just go out and buy any ASIC and reprogram it, in fact, you can't program them at all outside of writing software to support it.

Perhaps your friend has an FPGA and needs a bitstream programmed for it?

I'm just going by what my friend has told me. He said him and his friend have everything needed to make their miners but lacking the programming. I'm not sure what they were going to do when they cam to that point, but I would have just forwarded his contact information to whoever wanted to help out with the programming and let them talk it out.

These are specifically Bitcoin mining ASIC chips? Because they make ASIC chips for thousands of different applications, each is unique...

My co-worker said he has a home made BTC miner with ASIC chips. Everything is done he said except programming it. I'm not a programmer, so I don't know what he means by "programming it" but are there any people here that can help him out? He and his friend bought all the parts/chips from China already. Have the board all done and casing and just needs programming done. His friend's family is into an electronics business and was able to get their hands on ASIC chips according to what he said because of those connections. He told me things about a J-tag USB identifier and all stuff that doesn't make sense to me. If you want to maybe help in this little project, let me know and I'll pass on his contact information to you. I think they have parts for about 20 inits. That's all they wanted to build I guess.
