i Updated to this stratum proxy:  https://github.com/pooler/stratum-mining-proxy

I had to rewrite a few things and move some functions from the old alcheminer stratum.

I have gotten theese stats so far:
Since: 2015/3/11 13:56:54, accepted / rejected: 1385 / 103  17:42:20

So it is handling vardiff much better now. But will need to run 24hours to make sure it is working better.

Will try to check what is improved in slush0 proxy (couldnt get that one to work) and se if i can merge it.
Then i might start looking at pool failover and a mail function when a pool fails. If i get the time that is.

I am thinking about accepting donations later if i start to put some time into it. But all releases will be free for all.

Those changes sound great, and those stats are far better than what i've experienced lately !
 they are doing a promotion for a free miner for software development Ive been in conversations with the CEO.

along with accepting donations
I can probably get you a free miner if those changes work all we would have to do is pay for the shipping around .9BTC

did you have to add any additonal liniux libraries ? I know slush0 uses some newer libraries
for inastance version 1.56 uses agrparse

Some more stats from wemineltc:
Since: 2015/3/11 13:56:54, accepted / rejected: 3523 / 271

Now the reject rate is the same as ghash.io has with a locked difficulty. Will try clevermining also.

I did find an easy way to swtich to a backuppool if the stratum proxy fails to connect 10 times. Will try to make two failover pools.
It will be more work to get it to swtich back, but it can be done by restarting the miner och pressing stop and then go.
The backuppools have to be written manually in two files so it wont work from the homepage till i make changes to it.
Will test it tomorrow or on friday hopefully.

clevermining is a multipool so that should be a good test , numbers look good still

I am thinking of buying a used Mat 256Mhs scrypt miner.
The seller is asking 1970usd including 3xpsus, cables and shipping to me.

Is that a descent price for one of these miners today ?

Hello 970 USD is a bit expensive for a used device.  Check the price from a Alcheminer (a MAT 256MHs scrypt miner= a Alcheminer 256)
http://www.alcheminer.com/alchemist-256mhs/  brand new its $999.

For a used MAT miner whit no change of returning it when its broken, i guess 400-450USD would/should be oke.

hi guys,

how do you update your mat excalibur 5 miners manually??

i try to load the alcheminer update via the standard web interface way but it wont do it??

any ideas or help would be great.

Ditto I know its an old thread but I would love to be able to play around with the settings. It just doesnt feel right if you cant tweak it

Same here! I had the extreme luck of receiving my excalibur 5 the day before MAT announced bankruptcy, I must have been one of the last units to ship. Guess I ordered just early enough in this big lotto.

I'd love to be able to update the firmware, tried with alcheminer but it didn't work.. Anyone can help with this?

Witch coin do you mine?

[Afts]

I have only been mining on clevermining in the last couple months...

[lifeforcepools]

I mine here: http://pools.smarterhash.com - I always know which coin is paying the best - ALWAYS!

in all my testing I've found that the machine does best with a fixed diff of 36,684

I own two of them and they're running on my pools.



and we have a number of other members running mat machines also.

I recently shut down lifeforce pools since I opened http://pools.smarterhash.com to interface with http://smarterhash.com so miner could know the most profitable coin all the time and switch coins at any time from their browser or smart phone since there's always 8 to 10 coins vying for the most profitable spot


by the way - if any of you want to ssh into your mat machines as root - I know the password.

pm me and you'll need to send me a picture of your machine with today's date and your screen name on the sheet  - I'm not going to make it easy for someone to hack someone else's machine. - you know?

My private pool http://hollandsemultipool.nl/  now open for all miners

Do not trust to this site. 96 MH/s miner is more expensive there than 256 MH/s. http://www.alcheminer.com/alchemist-96mhs/

Yah noticed that to lol

[Rabinovitch]

I spent several hours last night for experiments with the pools and for updating OS and miner SW on Excalibur 5...  

Everything is OK, I did it.   Now it's in the test run at Wemineltc.

Later I will perform an upgrade of cooling system - re-applying the thermal compound and gluing a little heatsinks on the ASIC chips itself. Once those little heatsinks will arrive.

Here they are: http://ru.aliexpress.com/item/100pieces-lot-Wholesale-GDT-X9-9x9x12mm-9mm-Cooling-Aluminum-Heatsink/32376112849.html?tracelog=back_to_detail_a.

I have ordered 256 pcs.
