Now i know the limit amount of BM1384 chips you have/had.
chiguireitor seem up to the challenge, maybe he can scrounge up that berjillion S5 boards ^_^"

For the non daisy, usb hub still work, its a small extra expense, but very manageable, especially since i won't be getting 100 of them apparently. Good idea for slapping a Wifi adapter on the pi if ever.

Cool for SP NDA stuff. I guess this mean at least there is a channel of communication open. Hopefully at one point you get to tell us you'll have a batch of their chips.

Maybe we can setup something for the dead board. For instance i wouldn't mind buying dead S5 board and have them shipped directly to you.No point in having them shipped to me, then i reship them to you, especially since there's probably a bunch of them, dead already in the US.

What are you talking about? The Bitcoin core wallet? Which wallet? If you want a wallet that does this, the Feature is already available for almost all wallet. (Sign message)
And if you want offline signing, the feature is already available as well; https://bitcoinarmory.com/

I can recommend OgNasty, as i have personal dealings with him. I simply sent a message to him in the form he suggest and it did not take long, even though it was the middle of the night, to PM both traders with confirmation of fund being in escrow.

Then when i told him to release, he released in ... minutes? Overall it was great. If you can fork over the 1% fee, go ahead. If not, there's very good active escrow that do it for free or tip.

Give us a screenshot for the miner status page on the AntMiner's webserver page. A picture of your setup, your psu connected to it. Does it beep, is the light on the cold board on and if the red led is flashing, always on, or always off.

They could make great room heater instead of using electricity cooling for this winter.

I said "obsolete" when i should say efficiency is already one generation behind. And next gen chips surpassing the S7 are supposedly already in existence, however not easily available. For example the nice SP chips we were talking about making a 400-600gh pod at under 100w. So in short, a pod using the BM1384 could fall 2 step behind before 2016.

Since the chips are available with the S5, you're competing at that efficiency but your pod would be a great value for people who want to control the voltage without using special PSU's or downsteps. And only the S5 v1.91 board seem to take the downvolt properly.

And for getting them in lots of 6, i don't really see a problem in term of setup. I already run more Antminer S1's than any other miners, so i thought of the pod as a "upgrade" for them. Albeit i suspect your pod wont run on wifi.


The builder himself doesn't know my situation and what is my best target for ROI. Seeing how so many more people voted 50$, he probably did not imagine all the situations that people maybe be in. Or why people people are so interested.
Because at the price he suggest, This would be a much better option for me than getting a s7.(Which i just can't, the price is ridiculous) And is also better than buying more S5's which are insanely hard to find in Canada, at least at a reasonable price/proper seller.

For example the S7 is about the worse ROI of all my active options. Because the $/GH is just horrible. And more S5 is already what i'm doing but there are a few reasons why the pod is better;
-I could get all that i need from one deal and pay shipping once.
-Possibly better overclocking than S5
-Volt control (Awesome sauce)
-Lower heat density = less noise
-And i suspect easier management as i believe Sidehack said they would daisy chain connect to make it easy to run all the miners on one controller.

While the deciding factor is i can't run a S5 next to my head to me when i sleep,... while maybe 12 pods running at moderate freq might be. I need miners that will run in my room quiet.

If the amount is limited, then of course. I said "I'd fill 3kW with them" before knowing there could be so few, after all, he's going to have made over 1000 usb sticks.

But who knows maybe some people are sitting on dozens of dead board that would let sidehack make a few hundreds pods.

If that is not the case a single lot of 6 would be just as nice since i got quite a bit of S1 and old Scrypt miner to replace.


A small pod should be 30$ with USPS. A lot of 6 should be 45-50$. From experience with all the stuff i bought from sellers in the US so far. Its bad for one pod, but okay for 5-6.
If you decide to keep them, then i could see value in you doing that until they become unprofitable and you need to sell them to others. At either point i'd be interested in buying them.

I had not realized the value of this unit for people who have high electricity cost to validate the unit's ability to go down to 0.3. I have no argument there.

I figured if going from 0.5 to 0.3 and losing half the hashrate on the unit is your target, then i think that range is already obsolete for such a person, because of the price of the unit.

The math i did was undervolting the S3 down to the 0.5X range would give more hashrate for the same efficiency than that pod, for less than just shipping you a board back and forth.

And thats only because US/Canada shipping became crazy after 9-11. Its not because the S3 is a better unit.

In my mind, this unit you'd be building is already obsolete to people who pay their electricity, thus i would of imagined you would target people where $/GHs is more important than GHs/J because of how cheap their electricity is.


Why? Filling 2 breaker with this is only 20~ units.

Bitmain's text was something like "if its shipped less than 10 days after the initial shipping date, it will not be considered late." So this extrapolate into. "If its after x date, only then the late shipped order will be considered late and will then allow you to be compensated."

Yeah no, thats crazy. This could work with a electronic implant that is your hardware wallet key. Otherwise hell no.

I was thinking about someone that has like hundreds or thousands of Bitcoin that wish to keep his Bitcoin safe in cold storage but still in reach for many years, as a bet that Bitcoin's market cap will eventually beat other payment processors.

You keep those until its time to retire, then take it out and cash out, live the good live.

Exact same thing here. I pm'ed OP about this offer previously, i told him i'd be interested to pick up one or two if he end up breaking them down.
I guess its not a bad idea to leave the offer here, as this offer of mine will be valid ongoingly until i get 2 of them one way or another.

I know how vulnerable the usb port is for bypassing security, but i never pictured the process as having someone physically go to your house and show you how to do something you already know how to do (Use a bitcoin wallet).

Its not very any more complicated than that, you just need to keep the wallet instead, on a offline computer and then you have your cold storage that cannot be hacked. There's guides for that but if reading is somehow hard for you, then you just hire someone to walk you through the process for you.

I don't think your pod fit the entry-level miner to familiarize themselves with bitcoin either. I would recommend the sidehack stick for that. It doesn't make any noise, is cheap, cheap to run and doesnt take any space.

If you target the few people, only in the US, who want to run a single one next to their router for fun, learning and well just having one little miner that isin't meant to be ROI'd.

Then sure that could be your target, which would work if you only plan on making a handful of these.

Because as purely a recycling small scale plan, this would only be for US customers;

Ffor one pod or two, and i ship you a dead board. And then i pay for shipping back, that would be more money than just buying a S3 and undervolting it, getting same efficiency range and more hash and more hash/$.

Its totally okay if that is not your plan, but then i can't tell if its feasible.

You want to get creative? How about a non electronic sub dermal implant with a sealed capsule that has the encrypted priv key inside? All you would have to do is scratch that spot to be remembered that you're walking around with all that bitcoin.

You can always keep an eye on it and it cannot be stolen while you're not looking.

Then i wish you good luck.

I invite you to start a thread and act as a journal, so that people can keep track, learn and give feedback.

Personally it would be of interest to keep track of.

It's a bit bothersome for me since I have plenty of time to put time on repairing this board, but i'm afraid without some sort of map that show me what everything should be at, i can't figure out what the problem is. And once i figure it out, i don,t even have the pieces to repair the board.

In your case if you had several dead boards. You could more reliably just swap bad parts and probably be able to get a high % of dead board working by cannibalizing the rest of the boards.

Its not really easy to steal gold from a vault and those are insured. Bitcoin is a unknown store of value. Its not because its protected from fiat inflation that its a good store of value. Its volatile as hell and probably what people would give as an example to being a poor store of value. If the price change a lot, its not a "good store of value".

It may however be a "good long term hold investment" if you bet on Bitcoin succeeding its revolution.

If it fail you lost everything, Hence a bad store of value.

Meanwhile gold, even if ever government blow up/vanish, the world end will retain value.

I think toilet paper is a better store of value than Bitcoin

With proper volt control, these pods could be of interest at 50$(or one dead S5 board) each if one could buy enough in one go to be worthwhile. You would need to buy/sell them in small batches because of the the numbers are as such;

Buying a used S5 including shipping right now= 0.2$-0.26$/GH.

One pod + shipping to Canada = 0.4$/GH if the pod include the fan/heatsink you said you had somewhat available = no amount of fanciness can cover that price as a ROI-able investment. However;

6 Pods at 50$ea, which is the seller's price on the marketplace atm for a S5 + shipping would now give you a total of 340$~ so the % of money going to shipping is much lower. The final number become 0.28$/GH which is reasonable at the moment + quiet/volt control very much justify the extra price for people with cheap electricity.

I think the project with the figures you mentioned can be feasible at current market values. If you can pull it off before difficulty make this impossible or a new option lower the value of such a pod considerably, this would sound pretty tasty.

In current condition and prices(assuming it include the heatsink/fan already) i'd be inclined to fill 3000watts with these at home assuming they can do the 190gh per unit at 0.5~ efficiency.

Yes that seem too expensive. There's nothing to recommend since you probably pay 3 time what the network's average pay.

On a S7, if your total investment for one S7 is 2000USD, with a mere 2% increase rate it would take 500days to ROI, if there was no halving. With the halving in 9~ months, you simply have no chance unless the BTC price go up by quite a bit.

You could mine the S7 for a few months and then sell it before people realize it will be worth very little soon. Or before a S9 or other such major event that would make it obsolete.

The 15A breaker are designed to run at less than 12A continuous you won't have 200w to spare you'll be 60-120watts over limit for "continuous load" = over 3 hours. It would then be very likely to trip over any little thing. If you're lucky it wont cause a fire, too. I have breakers who randomly tripped because they were at 13A~ A less sensitive breaker might of burnt out.

Proper power bar will tell you that the circuit is overloaded as well. If you have actual 120v you should limit yourself to 1400-1440. Many have less however, the range is 110v-120v.

Really wish you could just bypass bad sections, ugh. But i guess they were designed to be cheap to make, not easy to maintain, repair or be resilient.

I guess Sidehack would be a good one to tell you this information. Making a thread just for this fiddling would be nice but i'm afraid there's no much more i can do with my knowlewdge.

I would say no burn marks, judge by yourself. The black smudges are thin layer of cooked thermal paste i believe. They were not there when i cleaned it. The board did end up at 205C~ when i tried to oven cook it.

My camera derp out and lose focus on the chip top side, which is weird, but anyways, even though that side is blurry, its still decent enough to see i guess.

That seem expensive, i'm not sure you could ROI the S7 before the halving. If you can, it could be worth a shot. If you cannot, i don't think there's anything on the open market atm that would work for you. If you need to pay for heating, instead heating with an ASIC would be worthwhile however.
