Because nothing is sketchy today
There's some sketch out there... but when you look back and think about gox, cryptsy, asicminer, butterflylabs, (to name a few) and then look at the landscape today. I dunno maybe I'm wrong.

Ahh, the Klondike! I had a full kit of boards and enclosure go missing on me from a DHL depot in Germany. Cost me 0.5BTC which was probably twelve cents at the time. Sad times, I still have the chips that were meant to go on those boards in their little pink esd wrapped stacks.
Lol - Those were the days.... things were so sketchy back then!

Interesting thread!
I always thought if a couple of con men and a felon could do it (BFL), then it doesn't seem that far fetched to be able to pull together the right resources to build a mining hardware platform provided you had legitimate investor funds. Back in the day, it was nice to see more collaboration; such as the Klondike effort with Avalon chips.

You got a full reel of those, by any chance?
Also, what is the topmark there? Looks like no logo, different from the machine pulls

These are BM1385E+ chips, older tech. I was just using them to show that you can actually purchase small batches of chips from Bitmain for repairs.

Buying the chips themselves is not a problem - they flat out ARE NOT AVAILABLE PERIOD unless you disassemble an existing S9 to get them (or R4 or T9).
As has been mentioned more than once already, BITMAIN DOES NOT SELL THEIR CHIPS.
PERIOD.
NOT AN OPTION.
If you see BM1387 chips for sale, they are either "pulls" or they are FAKE.
Since Bitmain doesn't sell the BM1387, they don't see any point in making specs and pinouts and such information available.

Although it is not something they offer to every customer you can buy the s9 chips from Bitmain in small batches (and at a full retail price). They come in little rolls like this:

Yes those are s7 chips, it is just for reference.
Hello kind folks.
I also want to build my own miner. And if we can make it generate electricity instead of using it that would be great, but I'm comfortable saving that for a future revision.
Today in the mail I will receive my very first soldering iron, a hot glue gun, and 100 units BM1387 stolen by my spies in the underground sweatshops. With this combination the project will be unstoppable!
Shall we be collaborating? Please send your qualifications if they are not already apparent, or simply ignore these crazy ramblings of another internet troll!

I'm kinda confused by the responses in the thread except for the first. I've been looking for the pinout info of the BM1387 chip for hours... buying the chips themselves does not seem to be a problem (unless every single supplier is selling fakes). I would think the short answer to the OP is yes.... you just need the pinout info and some electrical engineering knowledge.

I am often a bit shocked that Bitfury still sells THEIR chips - but I suspect it's inertia as they've been working with "major mining farms" and just selling chips to THEM for years.
I'm pretty sure Apple does a lot of it's manufacturing in China.
Maybe because they're sick of having over-reaching corporations peddling their slave-labor wares at ridiculous markups. Which is obviously not the case when you buy an iPhone.
I would rather build my own because I like building stuff.

I wonder if perhaps the analogy of "building your own cell phone" might help with all the folks asking about how to build their own miner. After all, why can't they just order all the parts to assemble an Iphone?
Why are folks happy to buy a phone from Apple or Samsung, and yet feel they don't want to directly buy a miner from Bitmain or Caanan but would rather "build their own"?
Just wondering since I too grow tired of the repeating threads.....

no one is selling BM1387 chips direct. There's only one company that makes them - Bitmain.

I am just developing PHs speed mining technology since demand is high for private PHs mining pools.
Maybe you and QuintLeo are right maybe not, who knows for sure.
My PHs speed mining technology is based on Algebra and pseudo-random heuristics.
I hope to have first tests run within 1 month.
Since hashing is based on deterministic algorithm the output is not random.
It may look random for non-scientists but it is not.

It may look random for non-scientists but it is not.
But since you don't know what the previous block is, or the time, it might as well be random. With those two things, you still need to find the nonce. It sounds like you think you have a way to get the nonce magically, without brute forcing it, or by doing some minimal work. If you had this, why do you need PH/s - the hash rate is only important if you are brute forcing the nonce.
Not random, sure, but certainly chaotic.
There is "no competition" because the whole concept has nothing to do with cryptocoin mining, and is NOT APPLICABLE to doing cryptocoin mining.
There is NO RANDOM to any cryptocoin algorithm - if there was anything random, the algorithm would not WORK.
Whoever "PH" is, they appear to be running a particularly ignorant scam for this "speed miner", or their scam is aimed at the particularly ignorant.
They're a crackpot who thinks they can find a specific set of "lucky nonces" that will be valid for new blocks - that's the "random" they were talking about. They don't understand how SHA256 works.

"pseudo-random heuristics" have ZERO to do with cryptocoin mining.
Nor does algebra - cryptocoin work is all about simple integer add and rotate operations, there is NOTHING complicated or random about it.
Exactly the reason I invest in the development of PHs speed miner based on algebra and pseudo-random heuristics since no competitors yet.
