Zero. Zilch. Nada.
Try reading https://bitcointalk.org/index.php?topic=2415854.msg24714338#msg24714338 point-3 to understand how ridiculous your question is.

Hmm, everywhere in this thread talking about power for it says 12vdc @ 8A. Take a hint...

Good luck finding someone using it.
Most folks now avoid all Ebang miners like the Plague because they are crap and support from Ebang is non-existent.
Start here in this thread and also here in this thread to get other folks opinions about Ebang and their miners...

Bitmains API - and for that matter just about every other mfgr of miners API - are all based on or actually using the CGminer API written by Kano back when he and -ck were still working together. While BM may have added a few new commands specific to their miners (I doubt it) if this works on one make of miner then in theory it should work on all of them.

Looks interesting. I'd give it a try but I stopped using Bitmain miners several years ago in favor of far more reliable gear from Canaan.
Can it work with any miner that uses Kano's cgminer API?

Sorry you bought those things. AFAIK no one here has ever had anything good to say about Ebang and their miners.

Assuming the miner uses the standard API (based on cgminer) AM should see it automatically. As for controlling the miner, that depends on if Ebang has it set to Privileged mode or not. Knowing Ebang's history it is probably locked down. If so you are screwed.

Melting plugs/sockets/cords means that they are the wrong size because someone does not know what they are doing. Correctly sized parts will be be barely warm.
Standard rule of thumb for constant loads is to keep actual loads below 80% of the plug/socket/cord/wire/breaker ratings.

A PC is not needed to control the miners. That said, a computer with browser IS needed just for setting them up and/or from time to time checking in on them. Any laptop works fine.

For power either find a licensed electrician or if going DIY be VERY familiar with your local codes and how to safely size the breakers/wire/plugs & sockets for the circuits. Knowing standard wiring practices is A MUST!
Not knowing what you are doing can kill you or cause a fire.

Thank you for the 1st useful info about it.
I had a feeling that it might be an existing firmware that has been re-skinned. I'll keep this thread open for the rest of the week but if there is no further input, after the week is over I'll be locking the thread.

I entirely agree. Personally I detest the idea of DevFee firmware. Just find it odd that there has been no mention of it here.

I do know that the AM home thread was moved by mods to the altcoin software area because much of its development and Forum discussions the past couple years has been aimed at said crap coins. However, as this deals exclusively with their S9 firmware I think this thread should be safe...

As for the cost of AM, I find it was a very reasonable expense. Yes cost scales with how many miners you monitor/control but that 1-time cost has lifetime upgrades and support and is applied in full to the cost of scaling to the next levels of how many you can control. I love it for my modest farm of 18 26 miners (mostly Avalons & forgot multiple miners per host).

Again, with per-chip tuning this at least looks interesting for folks that run S9's.

I saw mention of it in version notes for the past couple AM upgrades and so far have seen no mention of it here.
Anyone try it yet? ref https://www.awesomeminer.com/antminerfirmware Not sure if it requires also running AM to access it.

I only have 2 s9's left running so can't say I can give it a good test but seems the same as other 2% dev fee custom firmware here where one pays for the privilege of being able to tweak the heck out of a S9.

About the fee: This the first custom FW that clearly spells out how the 2% dev fee works.
From their above web page:

Again, curious if anyone has had a chance to kick the tires on this FW. Does it use the known security risk xnonce for the parallel mining?

edit: added emphasis to the dev pool hashrate

Could always try it on a Digi-Comp I or a Digi-Comp II 

AFAIK the Terminus only uses USB for data so there should be no limitations there.

Why does it seem that no one ever bothers to read existing posts to find that their question has already been answered?......
Start with First time/small miner reference for getting started followed by Current list of competitive hardware

As for Ebang and their crappy miners, ref https://bitcointalk.org/index.php?topic=5165794.msg51847126#msg51847126

which would make it technically an altcoin operation just as Lightning network is.
My other issue with them is Dr. Back being CEO: Kudos to him being cited in the original BTC whitepaper but IMHO his actions since then have NOT been in the better interests of Bitcoin. His part in backing Halong with the Dragonmints along with his holding back on deliveries just to keep them hashing for himself (on ckpool, over 300PH for several months) until threatened with lawsuits comes to mind for a start...

I agree. In Normal mode to give ~31TH the 40mm fan in the PSU is louder than the miner itself and even then the fan noise is not bad at all. Considering the PSU is barely warm even in high ambient temps perhaps the PSU fan speed can be lowered if some cares about that.

That said, even in High Performance mode the A10's are more of a 'whooshing' sound vs howlers/screamers like the Whatsminers.

Sure. All the miner cares about is good 12vdc power. It has no idea of anything else that is connected to the power source. If you can feed the needed power the miner will be happy.

Just be sure that your PSU has only a single power rail feeding the PCIe plugs. Using supplies with multiple high current 12V rails (internal power sources) is asking for trouble.

As long as the PSU has the power to run them both and you use ALL of the PCIe connections on the miner, sure. Does your PC have over 1.5kw of unused power reserve to feed a miner? Seems rather pointless though as the PC will always have to be on even it you are not using it.

Much easier to treat and power miners as what they are - stand alone devices.

Back to the 1st A10 I got in that would not keep a stable network connection...
Was going to try and flash it to different FW but....
1) is same version as the other 2 A10's, and
2) It fired up just fine today and so far after several hours it's stable. No dropouts whatsoever and holding at 31+THs on the GUI in Normal mode.

Go fig....
Whatcha wanna bet that it barfs when I move it from my test bench to upstairs to replace 2 of the uc/uv'd 841's....

That is covered by others earlier on in the thread if one bothers to read back a bit...
Right now I'm busy with other things like getting the 1st batch one to play nice with my router.
