1  Economy / Computer hardware / UK Guy - looking for 12v solar panels for mining project on: August 07, 2019, 03:44:34 PM
Hi,

I'm looking into a solar project to utilise 2 massive old batteries and a 300 watt invertor i was given

The batteries are 12v, 225AH each


and the invertor is a Maplin special 300 watt invertor.


So i am hoping to find some generous people who perhaps have some panels / controllers that they no longer need.

Since i only have 1 invertor rated @ 300w, which i wouldn't trust running 24hrs/day @ say more than 75%, i'm guessing i need about 200-300 watts worth of panels.

I know zero about solar, but am guessing all the gear must exist for me to connect diff types / powers of panels to 1 controller, and to my batteries, so i can link to the invertor...

I've seen these on FB Market place https://www.facebook.com/marketplace/item/416919618915712/ or https://www.facebook.com/marketplace/item/700632917027043/ , but have no idea how, if they could be used to charge the batteries i have.

If anyone has any old panels / convertors going cheap/free, please drop me a line.

Thanks

2  Economy / Computer hardware / UK Guy - I'm wanting to buy old multi core, multi cpu servers for BTC on: August 07, 2019, 02:41:53 PM
Hi,

I'm wanting to get into cpu mining, and am looking for 1 old server to do some testing.
Xeon, Opteron, Threadripper, heck, even EYPC (if i'm lucky)

I'm currently running a 1800x (8c/16t 32GB ram) so needs to beat that...

Ideally looking for along the lines of 16c/32t over 2-4 cpus. (32cores would be even better)
At least 8GB per cpu, preferably 16+
Not bothered about hdd. (I'll be using a 60 SSD)

Must be working.
Must be able to run Win 7 and 10 and also Ubuntu 14.04.6 LTS and Ubuntu 16.04.6 LTS

I know it looks like i'm asking a lot, but i'm pretty sure that there's loads of older gear sitting around do virtually nothing but heading towards a skip, so no silly prices.
Alternatively, if anyone out there has this kind of kit sat on a shelf not doing much, but doesnt really want to sell, i'd be very interested in hiring a server for while, just need to remote access, and have the above OS's on it.

I'm in the UK (Yorkshire), and can travel a reasonable distance to collect, but delivery preferable.

Thanks

3  Economy / Computer hardware / UK Guy - I'm wanting to buy large HHD's for BTC on: August 07, 2019, 02:23:42 PM
Hi,

I'm looking to expand my hdd mining system, and am looking for large hhds, can be new or used, just gotta be cheap, and willing to take BTC.
If you have anything over 2TB, i'm interested, over 4TB, more interested...

I'm in the UK, and unless your happy, safely boxing and shipping em, would prefer you to be in the Yorkshire area.

If they're 2nd hand, and/or archive drives (SMR) please be very reasonable with your expectations, they can die at any time, and are generally much much slower, noisier, and more power hungry than new drives

Give us a shout

Guys,

I need help from 1 long standing (read - trusted) member.
I really need to do a test for 24hrs with minimum of a 6 x 1080ti rig. Can split proceeds, please PM if you're prepared to take a gamble.

7  Alternate cryptocurrencies / Service Discussion (Altcoins) / MagiCoin (XMG) miner for rent on: May 26, 2018, 01:03:14 AM
Guys,
If anyone wants to have a little fun mining MagiCoin, i have a great little rig for you to try.
Minimum of 3 hours, so about as cheap as can be.
Try it, you might get lucky.
Since i'm new to renting out, and just testing, i am only charging for a hashrate of 200kh/s.
This is well below the pool user limits, but actually i'm finding my avg rate is more like 230kh/s.
I've also set the price to 2% less than recommended, so grab a bargin whilst i'm feeling generous.

Hi there,

I'm after a favour.
Does anyone have a AMD EPYC server that they would be willing to run a couple of hashrate benchmarks on for me.
Literally a few minutes work, using CPUminer-opt 3.8.8.1 ( https://github.com/JayDDee/cpuminer-opt/releases )

9  Alternate cryptocurrencies / Mining (Altcoins) / Genuine small miners coin required. on: May 08, 2018, 05:50:22 PM
Hi guys,

Well another day, and another load of s**t coins.
ASIC resitance blah blah blah, gpu resitance blah, blah, blah, cpu only...yeah right
Ok, so i get that any algo if popular enought and profitable enough can be hacked, but seriously coders is there no one out there who even tries anymore.
Has all of crypto just become ICOs and get-poor-quick schemes.

Way i see, is like this...
ASIC manufactures, gpu farms, and cpu farms, all have one thing in common - GREED (i'm not taking about the small guy who has saved and saved to buy a single 1080ti rig, i mean the mega guys)

So they are looking for something they can buy as a standard itm, cheaply and duplicate easily.

So devs, why not look at producing a coin, that genuinely is distributed, genuinely for the small guy (or girl)
A coin which utilises the cpu, the gpu the system ram, and the hard disk, and a coin in which you mine solely from the wallet...no pools, and if you multi cpu/gpu, then the other requiremenst go massively.


Lets say a generic desktop has a cheap quad core cpu, a 750ti, 1030gt ish level gpu, and 4GB ram, and 1Tb hdd.
SO if we make that our base level.

The wallet asses the hardware, and as part of the "mining process" some info has to be "plotted to the HDD" just like burst say 500Gb of the 1 TB.
Next the wallet miner can utilise eith the cpu, the gpu, or both, using the system ram as a buffer.

SO, yes you can have 1000 desktops and a 1000 wallets, but on a single PC, as soon as you add say a 2nd gpu, you need double the ram (8GB), and a 2TB hdd.
3 gpus, and u need 16GB ram, and 4TB hdd
4 gpus, and u need 32GB ram, and 8TB hdd
5 gpus, and u need 64GB ram, and 16TB hdd
6 gpus, and u need 128GB ram, and 32TB hdd

Now YES the server farm guys have 192 zillion GB ram, but not necceasrily the match HDD space, and vice versa.
Yes it screws even the modest single 1080ti guy
BUT it means pretty much anyone with core2duo with office gpu upwards should be able to mine it.

Anyway i dont have the answers or the ability, but some bight spark dev surely can invent something alone these lines to help the small guy Smiley

Heres hoping

Guys,

Just a heads up,
I have been pushing for MMR to list some Cryptonight rigs, and today they emailed me to do some testing.
They now have a small section
https://www.miningrigrentals.com/rigs/cryptonote

I am currently testing renting out my own rig on Electroneum, feel free to have a look.

13  Economy / Service Discussion / Multicore processor (Ryzen 8 core) / server required for a few hours on: September 19, 2017, 01:48:35 PM
Hi there,

I'm trying to work through a mining project, but need access to a pc/server with a decent amount of cores for say 2-4 hours.
Ideally i'd like to be able to remote access in( i currently have Teamviewer installed), transfer a wallet and blockchain across (about 1GB) and try mining for a while.
Ranting to asses hashrate with diff miners across diff platforms, so i can gauge which is best way to go forward.

Any one offer any assistance please?

16  Alternate cryptocurrencies / Mining (Altcoins) / Needing a SHA512 miner on: September 04, 2017, 07:13:16 PM
Hi,

I'm searching for a windows binary of a SHA512 miner.
I'm up for trying any. Would prefer GPU version, but CPU will be fine to.
Must be able to solo mine.

Anyone know of one, please let me know

Thanks

17  Alternate cryptocurrencies / Mining (Altcoins) / Compiling Windows Binaries from Github on: July 30, 2017, 05:06:01 PM
Hi there,
Just wondering if some kind soul can help out.

I come across various wallets from github, but they don't have windows binaries.
For each one i have come across, i have read all the instructions, tried to download all the software, but i find that nearly all the links are wither broken, or take you to just a generic place, so you have no idea which version to use.
They even if you are lucky enough to find all the right software, you follow the commands and, nada, it doesn't compile, or work.

Is there someone out there who can help me, by pointing me to the software i need, and walking me through the process please.
I'm guessing that once i have everything in place it's quite a simple procedure, and would allow me to compile various wallets.

I have Win 7 or 10, usually 64 bit, but can build a 32 bit rig if need be.

An example wallet would be https://github.com/Voyacoin/Voyacoin
I don't need this actual one, since a very kind person found his old windows wallet and sent me it, but this is the kind of thing i'd like to learn

Regards
J
