Hey All,

I'm trying to help my nephew out with learning about mining and everything that goes along with it: research, reading, getting it wrong, persistence, etc. I was thinking about getting him an S7-LN or S7, but I already have the stuff below.

Any insights on mining Ethereum with a Gigabyte Aorus Radeon 580, 4GB, 256-bit GDDR5, using a Dell Optiplex 780 Tower with an Intel Core 2 Duo 2.93GHz with 4GB of memory? It has Windows 10 64 on it. I have them gathering dust.

As far as I remember, the Dell has two PCI slots, one PCIe x16 slot, and one PCIe x1 slot, for a total of four.

I assume the card I have is a no-brainer, but how many would the machine operate, with risers or whatnot if necessary? Will the Dell be able to power the one 580 internally since it is only one? Or, do we need an external power supply even for that? Any thoughts, tips, tricks, pitfalls, etc?

I want him to figure it out as he goes, learning along the way, but I don't want to encourage him further if the tower will only run one (two, three, seventeen?) cards. Plus, I don't want him talking (read: suckering) his mom into buying him an expensive new card that he can't use.

The machine won't be used for anything else so the optical drive can come out and it can be stripped down and left open for airflow.

I'm reading up to make sure I point him in the right direction, but any ideas, suggestions, threads, pointers greatly appreciated!

Thanks in advance.

Welp, I was out, really out, no more rigs, no more futzing about, all done.

And then, my nephew got me. "Pleeeease teach me about BTC, pleeeeeeese?"

So, knowing how kids can be, I gave him a couple of my old sidehack compacs: GekkoScience Compac BM1384 Stickminer Official Support Thread.

He has stayed interested, so I have gotten him a couple of sidehack 2Pac seconds to help out a good cause (see sidehack's sig) and Laura's page, that I'll give him next time I'm over there. He's been learning about volts, amps, burning his finger, power supplies, cutting down two-liter bottles to make an enclosure, all the fun stuff.

Hence this thread, does anyone have a dirt cheap, mint condition (heh), S7-LN or 135-chip S7 gathering dust that they would be interested in selling me?

I don't want to spend much, given that he may still lose interest, but I would like to be able to give him something "nicer" relatively soon. He's been good, and has been sending me snips of cgminer showing his compacs running every few days or so. Frankly, I was pretty sure he was going to burn them out playing with the speed and voltage, but he got them purring right along. Good for him, and it's fun to have a project we can share together.

I'd love to just get him an S9 hot off of the presses, but who knows, he's a kid, and kids move on. No reason to waste the money on something like that if he does. I figure, get him an S7, and help and teach him along the way, and maybe he'll get his own S9. Or, his parents will start charging him for electricity. HA!

If you're willing to part with one (POSSIBLY two, but they would have to be CHEAP), please just PM me, no reason to post here. EDIT: I should add, I am quite familiar with value, pricing, ROI, what they sold for last summer, market flux, etc. Please save the rube/noob offers for Amazon or eBay or whatever, save us both the time.

Usual drill, either via escrow here with someone we both trust, or PayPal or eBay.

Thanks so much!!

I'm sure with all the wild rigs out there, someone must have tried this. So, any thoughts anyone? The boxes with the S1s would be about 0.75m below the window that would be used for exhausting the heat. No kinks in hose, but two nearly 90deg bends.

Any downsides? Things to look out for? If I'm going to contribute as efficiently as I can to gloBULL warming, I want that heat outside post haste!!

[SOLD! ==>First lil' rig]

Hey Folks,

I gotta tell ya, I'm having more problems with buyers. Sheesh. Feel free to make offers on the prices below.

I'm selling some stuff. A couple of points:

• I only take bitcoin
• It won't be much, but if you don't trust me, we can find someone to escrow, or I can set up a private auction on eBay, if that is still possible (milhouse*vanhouten)
• I really don't want to split these up, it doesn't seem worth it
• Feel free to chime in with what you think they are worth, but if you are interested, PM me with your offer, and how you are comfortable paying
• I look at this as a hobby, a fun little investment hoping bitcoins skyrocket over the coming years. If you need to make money, this probably isn't the place for you
• Sorry about the crappy photos, the camera just ain't doing so hot
• For expedited, trackable shipping: 0.012BTC for each USB rig in the US. 0.026BTC for the Cube in the US
• They're all packed up and ready to go, I can get them out as soon as we agree, any day except Sunday
• Overseas is fine, but I will have to check on shipping to get your ~gift~ to you, and confirm the charge with you first

Thanks for looking!

SOLD! ==>First lil' rig:

D-Link Hi-Speed USB 2.0 7-Port Powered Hub (DUB-H7): http://smile.amazon.com/gp/product/B00008VFAF
Six Block Erupter USBs (yes they are in Ant cases), each with two (2) lil' heat sinks. They hum right along. They are all black.




SOLD! ==>Second lil' rig, a bit o' Frankenstein:

Anker® Uspeed USB 3.0 7-Port Hub + 5V 2A Charging Port, with 12V 4A Power Adapter and 4ft USB 3.0 Cable http://smile.amazon.com/gp/product/B009Z9M3DY
Thermaltake Mobile Fan II External USB Cooling Fan http://smile.amazon.com/gp/product/B00080G0BK
Six Antminer U1 USB miners with ridiculous overkill on the cooling (I told you this is a hobby) each with two lil' heatsinks, and ONE LARGE ONE with Arctic Silver. They each blast along at about 2.2 GHz and never get warm. Heh.






==>Third, Das Cube.

Again, hobby. Like I said, I can't get the camera to work right, so you can see the cube to the left in the first picture above. I planned on changing the resistors, but couldn't find anyone to do it. It is heavily modded for cooling too. I opened the case on both sides, as you can see below, and each chip has a heatsink on it, and it hovers right around 41GHz while on "overclock". If you can switch the resistors out, and place a second fan at the side, you'll be smoking along.

Optional For plug-n-play: Corsair CX600 power supply for Cube, non-negotiable: 0.105BTC. Shipping will adjust accordingly.




SOLD! ==>Finally, fourth lil' rig.[s/]

AH CRAP!  I forgot! I also have a 10 GHz Butterfly Labs Jalapeno! So that would be 0.41BTC plus the shipping rates above.

Does anyone know offhand whether the lil' 80mm USB Thermaltake fan:

http://smile.amazon.com/gp/product/B00080G0BK

can be unscrewed and the speed control placed on the other side? It doesn't ~look~ like much of an issue, but I also don't want 37 little bits that I have to build a jig (not doing) to get back together. I want to attach it to a rig, but that knob is in the way.

Thank you.

Has anyone got any experience with, or links concerning, accepting BTC on eBay?

I have a few things I would like to get rid of, and I wonder if anyone has any tips, or tricks, or pitfalls?

Thanks in advance!

I swear to Jeebus, I saw someone either commenting on, or noting ideas on, how to overoverclock a Cube. Well, then again, I could have dreamed it....

Does anyone know a thread or source for such a thing? I've searched up and down, but needless to say, nearly every Cube thread mentions overclocking almost as often as it mentions the Cube.

Any thoughts? And thank you!

The problem with this particular forum is that it seems that many (most?) of the posters don't really know the slightest thing about basic economics. Not the Austrian School, the Chicago School, Keynesian economcs, Paulsy Krugmanian, Bastiat, Hayek, Mises, Prescott, Lucas, zip. Nada. Nothing.

It reminds me of the people who will happily discuss US budgets and monetary policy, but don't know the first thing about fiat money, the Federal Reserve, what the power of the printing press actually means, or anything else. They are the same people that think that there is a Social Security "Trust Fund" and never pause to think what it would mean to loan money to themselves.

As a greater commentary, beyond this board, it's a very sad thing. This stuff is important.

Hey All,

Been reading here for years, and never had to register/post because I always found whatever I needed or wanted. It's sort of odd to me, but obvious, the more mature a board becomes, the less likely I will need to join or post. In Olden Timey Days, you had to join and ask questions--that doesn't seem to be the case any longer.

Anyway I forgot about the restrictions about posting and PMs, but I still managed to send CrazyGuy BTC0.89 for an ASIC Miner Cube:

https://bitcointalk.org/index.php?topic=375247.0

So now, I begin the wait until I can PM him the transaction ID and my shipping info. Damn hell ass waiting. Heh.

Either way, the topic is my motto, and yes, "embiggens" is a perfectly cromulent word.
