[WTB] Outdated Miners for Research

[ncsupanda]

Trying to learn more about the ASICs on the market so I can continue learning to repair them and also design them. I started with a pair of 1.3 MH/s Fury from Zeusminer and have also worked on a Gridseed 80 Chip Blade but I want to know more about how different companies have approached Cryptocurrency mining.

Recently Purchased:
-1.3 MH/s Fury
-5.2 MH/s Gridseed Blade
-30  GH/s BFL Single

Looking for:
Anything not listed above that is below 50 GH/s (SHA-256) / 5 MH/s (Scrypt). Learning about scaling hardware to larger designs is not my end goal.

I'm using these for personal student research and not for mining so please don't give me prices based on the idea that I'm trying to make a profit. I'll also document all of my repairs/work and report them both here and in a few research papers related to my ASIC Design classes I'm taking.

If you decide to PM me then I may choose to copy that PM here. I also buy broken mining hardware.

Thanks!

If you're in Europe I recommend Hamuki:

been wondering, 5gh/s brings you how much bitcoins per month?

Use any profit calculator - takes a few seconds to google and input what you're asking.

Does not pertain to my post and is practically spam.

I have a hex4m I'm itching to get rid of. It actually runs at 400GH, but I won't charge anything ridiculous for it because of its low efficiency (1w/gh). I don't have the top heatsinks (those guys fetch a pretty penny). I'm looking for $20 + shipping.

As well, I've got a few 333Mh/s block erupters, a Klondike (although I'm a little partial to it, and it has no fan), and a couple of antminer s1 hashing boards (no controller). Let me know if you're interested in any of it.

The Klondike was such an interesting piece of equipment - do you have a price you're looking for on that? If so, I may be interested in buying them all as a set.

I already have an S1 to begin looking at after my current project but it isn't quite the hardware I'm interested in. I'll update the above.

To be honest the klondike is the favourite piece I have, so I'll part with it for $50+ship. Yes, its pretty steep, but I haven't seen one floating around for a while and it will be difficult to replace.

If you'd like to buy the whole set, that's good too. I'm located in Ottawa, Canada--I hope shipping won't be prohibitive.

I got a old hashfast asic board that is mostly barebones so just the chip and board. I am not even sure if it works anymore.

[helipotte]

I have some 10Gh Asicminer blades.  They are version 2.  Also have some BFL jalapenos that hash at 8-9Gh.  Bitfury stuff too.  The Black arrow boards.

These are more along the lines of what I'm looking for. Are you willing to let go of all of them?

This is the one you wanted $50 for right? I couldn't justify that price right now.

I could sell you 2 better quality usb sticks.

an ice fury uses a single bitfury chip and a dual fury uses 2 bit fury sticks.  I am usa based.

I run them with bfg miner 4.4

the 1 chip clocks from 1.5 to 2.1

the 2 chip clocks from 3 to 3.8
 
they fit in a small flat rate

How much are you looking for? I feel like they aren't worth much but they would be fun to tinker with.

I have an Antiminer U3 that just stopped hashing last week after only 3 weeks of operation, might be perfect for your project (it's <50gh at factory volt/freq).  When you plug in power the fan fires up, when you plug in the USB the USB power led comes on, when you start CGminer the mining led flashed on a few times, but then stays dark.  The mining LED should come on and stay on, but it doesn't and cgminer never even recognizes that a device has been plugged in (but it will give an error when you unplug it, which I find strange).

I was going to send it to Bitmain to see if they could repair it, but I'd rather give an independent guy a shot at it.  Let me know what you think, I could sell it to you as is and then buy it back from you if you're able to fix it.

If you want to ship this item to me I will pay the return shipping once it is fixed - if I can't fix it then I'll buy it from you.

Let me know if that sounds reasonable. I wasn't originally looking at a repair service but it's a fun idea.

Done. Phillip and helipotte let me know what you'd like for your units.

Thanks all.

Great guy to work with and help learn this hardware.  I sent him a broken U3 at my cost. He fixed it no charge, and I ended up selling it to him because I have 2 others and didn't really need it, it has a better home now. Great guy to deal with, very helpful, knows hardware!

I guess have some decommissioned Chili boards from MrTeal (30Gh/s), if I still can find them .. let me look and I'll post again.
With MrTeal still around, I know you can obtain detailed instructions

I would love to get one of these units if you were able to find them.

I have a S3+(450 GHs) for sale, are you interested in this miner

[Gastro93]

When I first got into mining I made a horrible mistake with buying the asic block erupter 30gh. it can be found here
http://www.amazon.com/ASICMiner-Block-Erupter-Cube-Miner/dp/B00H8K3MZU

Anyway I have that as well as a raspberries pi, cords and everything else you need to run it. What would you offer for that?

Not sure  what shipping will cost you to NC. I would offer around 10 for it.

I have some Steamboat GB Klondike boards.  I would be happy to let these go for free as long as you pay for shipping.  I am in 60077

Can you calculate shipping for that to 27607?

USPS Standard post. 3lb box - $8.62

0.04 BTC, you send first? We can do escrow but it's not much BTC.

[Wintermute420]

That works for me.  Send the funds here - 13uRKpzqsEs7KtmUcB6dZ1tCu6yUeQ4KN3  I will ship the miners over the weekend.  I will let you know when they are on their way.  Could you PM me your address?

Are you interested in one of each?
Gridseed 5 Chip Including shipping 0.09939 BTC I also have one that is volt modified if your interested, and some that I blew up I can throw a couple of those in for free if you want
Antminer U2 including shipping 0.09939 BTC
Antminer U3 including shipping 0.2032 BTC

If your interested in more then 1 of each we can talk about a discount as shipping would be minimal for extra units

Those prices are reasonable - it's just a matter of not using the miners to mine which leaves me in a bind.

I would rather buy older units.

If you aren't going to mine with them I have 4 x 5 Chips grid seeds i nuked when trying to learn how to volt mod them you can visually see that one of the power chips has blown up but if your just looking for a researcher toy Ill ship one to you for nothing if you pay shipping and if it helps you a tip would be acceptable how does that sound?

Want like the cheapest USPS Possible or something with tracking like Priority Mail? do you want only 1 or would you want more? PM me your ZIP ill get a quote for you from stamps.com or UPS we have accounts with both here at work and I have 2 on my desk so i can ship them today

[Quinn]

if the miner isnt broken, and its a 60 ghs BFL how much?

[ncsupanda]

if the miner isnt broken, and its a 60 ghs BFL how much?

Calculate your shipping costs and make sure it is worth it - I would buy it for ~20.

That's sort of my go to price.

[lissandra]

do you take those usb miners?

[bitcoinbelieve]

I have bfl 50 ghs (it works) and wants to sell it. (it comes with bfl power supply) You said you generally buy miner for $20 but does that price includes shipping?

[Mikestang]

Please send my U3 back to me, I included paid postage, all you have to do is drop it in the mail.  It's been several weeks since you said you would send it back.  Please send it back immediately.

[ncsupanda]

Please send my U3 back to me, I included paid postage, all you have to do is drop it in the mail.  It's been several weeks since you said you would send it back.  I'm starting to think you've stolen it from me.  Please prove me wrong and send it back immediately.

I have not stolen this miner - and I've messaged you accordingly.

I've been absent on these forums and apologize for my lack of communication. I'll be sending this back to you tomorrow and hope all is well. I've also agreed to pay you in Bitcoin for any lost mining due to my tardiness.

To be completely transparent I've been working (besides my two day jobs) to finish a solution for the Scrypt miners "Silverfish" and have been working with the manufacturer to fix a long time problem on their units.

Thanks
