I've recently moved and upgraded the electrical in my garage with a dedicated 220 line for some new miners and am looking to throw some hardware at it. I'm trying to get my hands on the latest in mining hardware but am having a tough time finding anything through normal channels and the manufacturers are not responding. If you've got some hardware to sell, I'm very much interested.

The count right now is:
s7@~5.13TH/s
s7@~4.82TH/s
s7@~4.97TH/s
s7@~4.95TH/s
s4@~2.29TH/s
sp20@~1.51TH/s

for a grand total of ~23.67TH/s

The ROI is theoretical because I just started mining again and when I loaded up my old wallet there were still bitcoin in there from the cpu and gpu days which I used to get all the hardware. I have positive balance in my wallet so I'm considering it profit.

I have 5 scrypt miners with a total of 6.57MH/s those are mostly just as desk ornaments at work and to mess around with altcoin

My setup at work, doing some scrypt mining and my lottery gekkos.

and the mini farm at home:

I've got old miners laying around that won't do too much to help my bitcoin mining but are they profitable for some other altcoins possibly?

Are any of you using older antminers for anything other than bitcoin?

Thanks for all the great feedback everyone!

I've already got the site up and got twitter and IG accounts up and linked so that people can reach out if they have questions they want to ask directly. I think I lucked out and got a really good URL. The link is in my sig now.

My simple answer and the one that's been the most useful so far is "what is a bitcoin" since the answer I wrote was intended for friends or family, I stayed out of what has normally bogged people down in conversation when they've never dealt with Bitcoin before.

I've decided to start with the stuff I have the most experience with so I'm going to be doing some writeups this weekend on basic miner setup and components. I've already been getting questions from IG so I'm going to be answering those to the best of my abilities ASAP in the attached blog.

The addition of a page detailing what a satoshi is and how micropayments are regularly used is a great suggestion and I'll definitely be adding that as well.

The site is still in it's infancy, I'm actively creating content and editing things to be as clear as possible and I'm completely open to any constructive criticism.

Thanks everyone, please keep the suggestions coming!

I've been coming here for answers for a very long time and just recently started contributing and I see people ask the same questions dozens of times. On top of that, I'm sure everyone on the forum has had to explain to a family member of friend what, exactly, bitcoin is and how it works.

Since I've had that conversation a few more times than I care to, I decided to make a place where you could send the curious loved one and it would break it down in mostly normal English, with out having to wade through forums. I don't have all that much up yet and I'm not sure what the self promotion rules are here so I'm not linking to the site. I'm just looking for what you guys think would be the most useful stuff to put right out in front.

I've got a basic breakdown of how I've been able to get most people to understand Bitcoin. I've got a, probably much longer than it needs to be, breakdown about mining.

I plan on having step by step walkthroughs on how to set up stick miners and S3s and stuff like that for people who want to get into mining and just don't know what all is involved.

What do you all think should make the short list?

That's great news, now I don't have to scramble to get this all set up to return in the next 2 days.

I'm having an issue that I'm wondering if anyone has seen before. I ordered 2 R4s in January and set them up on my local network monitor which I guess gave me a false sense of security because they've both been live on the network but apparently one stopped working some time ago.

When I logged into it the GH/S(RT) said 0.00000 and one of the boards has no temp info. I tried a software restart a few times to no avail and after cycling power I now get one board running and ~4.7TH/s so half output.


Has anyone seen this before and found a fix? Trying to upload the .tar.gz for R4 firmware from the antminer site fails.

I have 3 days left until I'm out of the 90 day warranty window expires but shipping this thing to china seems like a bit much.

I'm looking for the most efficient setup for 2 R4s in a home on 220 so any insight is welcome on better PSUs

So one Psu per R4 until an APW5 can be ordered, thanks.

I just ordered some R4s and I have an APW3 on a 220 outlet, can I run 2 R4s on that one power supply?

I have a couple of APW3s so is running one power supply for each R4 better?

Should I just bite the bullet and get an APW5?

I can testify, I've got on of Sidehack's modded 135 chip S7s and it's been humming away at over ~4.25Th/s much lower than stock voltage quite happily.

How do you guarantee that?  Ehe second user, the second address  and again 50 THs .

Me myself would have been necessary to 5 users for 250 THs home mining.
This of course does not mean that I will take part from this. I mine BTC not some "fork"coin.

I honestly think this sounds like lunacy, I was just trying to be constructive. The highest hash rate I've ever had at home is 25Th/s so I was just throwing a number out there.

The idea of my old hardware earning BTC at a decent rate again is intriguing but how to achieve that is a troubling question. Maybe IP restrictions on hashrates? I know you could VPN different miners to pool their hash rates but I really think that would be too much of a pain for massive industrial farms. It would at least encourage the home miner to join this fork.

Single user hashrate cap? no one user can hash over 50TH/s on this proposed fork. Something like that to ensure that no huge farms mess everything up in your new Utopian society?

would there be a difficulty change? People have hardware gathering dust because it's isn't profitable the with efficiency of that hardware, why would they fire it up again at a loss for your fork?

I've been struggling with this issue in a few locations for the past 2 years. I've tried a cheapo 4 camera setup from ebay but the one time that they were needed the intruder unplugged the router rendering the system useless... I'm upgrading that location with cameras that have local storage. I tried Ispy but the yearly subscription is annoying and if you have multiple instances it's tough to keep track (they don't contact you when your subscription is about to end).

As a plus to the recent boom in NAS sales, the major manufacturers have started really beefing up their software so the two bigdogs in the market (QNap and Synology) offer camera software built into their NAS boxes. I have been able to try out the Synology setup but I've heard that the QNap setup works just as well. It's pretty straight forward and I don't think many robbers would think to grab your storage device while running out the door. They both come with limited licenses for channels (read: active cameras) so you have to purchase a license beyond the default per camera you want to use, the synology licensees are a one time cost so it comes with 2 license but I have 3 cameras so I had to purchase 1 license($45) for all 3 cameras to work.

what other coin (sha256) are you mining with your asics? are s7s now more profitable mining something other than bitcoin?

Looking forward to it, keep up the good work!

Right now that's the only reason I'm hanging on to them.

As I'm sure is the case for many other people, I have a ton of hardware laying around that isn't profitable for bitcoin mining at the moment. Is there something more useful to do with my S1, S5, S7 that's taking up space other than a once expensive paperweight?

Is anyone having good experiences with multiminers that just throw hash power at altcoins?

I've got a few scrypt miners that I use to convert various alt to BTC regularly but my ASICs are much more high powered and efficient, is there something else to be done with them?
