I have ~200KW available in my new 144 S7 farm located in an hydro power facility in the north Catalonia(Spain). As I have a very cheap flat rate for a continuous 1MW power, I think it should be interesting to offer the possibility to host old gear which you have just unplugged or you are going to turn them off because of the last huge difficulty increases. Specially EU members who usually pay very high KWh for industrial and domestic rates.

I would host your old miners with the following conditions:

• No fixed hosting fee.
• But we share the 50% of the miner hashrate. Each day the first 12 hours it will be mining with your credentials and the other 12h with my ones.
• I promise to keep them plugged until they are not able to pay for 0.015 EUR/KWh electric rate. Lets suppose 100% PPS earnings per day converted to EUR at the exchange rate of the moment.
• After this I will just shut it down and remove it from my farm. If you want it back to keep it as a souvenir then you pay the shipping expenses.
• Miners power efficiency should be < 1.2 w/gh. It doesn't matter the model. Antminers, Dragons, SPs...
• I will pay 0.0001BTC/Ghs(of the miner hashrate) to cover the shipping costs if and only if you include the PSU. If you do not include a PSU then you pay all the shipping expenses.
• The miner will be up the following day after the reception.

I can demonstrate I am administrating the mining farm in several ways:

• Photos
• Bitcoin wallet address(with digital signature) where do I receive the daily earnings from the mining pool, equivalent to 600THs
• The hashrate of my username in the mining pool by api key.

So do not hesitate to ask for any information if you have any doubt.


If you are interested, answer this post or sent me a PM with the information below so we can arrange everything.

Hello Bitcoin community,

This is the first post I do on the forum and I would like to contribute with a method(discovered by chance) I used to revival some of my Antminer S3+ controller boards which bricked after a power off/on cycle.

I am the owner of a small  (80kWh) and I started to mine Bitcoin since the GPU era. From October I'm running a farm of +100 Antminers S3 powered by my turbine. From all S3s I only have had problems with 3 of them which died after a power cycle. After this the Ants remained idle with the red LED blinking and the green led of the ethernet plug dimly litting. They did not start to mine anymore even It was not possible to access them by ssh or web.  I tried desperately to restart them hundreds of times without success, so I concluded their controller boards were dead.

Looking for a possible solution in the forums, I tried to reproduce the Taugeran's Antminer S1 / S3 revival guide(https://bitcointalk.org/index.php?topic=775662.0) using the serial TX / RX pins of my Raspberry Pi. The fact is that when connecting the serial/debug controller board TX pins to my raspberry I accidentally made a bridge with the controller ground, and after powering on the miner tataxan!!! It resurrected!! Then I tried to reproduce the same with the other two S3s and they came alive as well!

So basically these are the steps you should try if you have faulty boards with the following symptoms (red LED blinking and green light of the ethernet plug dimly litting).

1-> Remove the top cover.

2-> with the Antminer powered off, make a bridge between GND and TX as indicated in the picture. You can do it with a paper clip. No need to solder.



3-> Power on the miner. Now it should be alive!!

4-> Remove the bridge.

5-> Cover the miner again(if you want)

Hope this will be useful!
