Ugh.
I just read about this on indiegogo. I ordered one the Canaan Avalon Nano 3S and I was excited to get it.
I already asked for a cancelation and refund, but I feel it's already too late and they already arrived and were seized.
I thought maybe I could try to reach out to customs if that was possible. But not if I have to be there in person. But sounds like with FCC violations, it would be impossible to let them release the item.
Would be nice if Canaan would release a revised batch that do comply with FCC. Though I feel even that would not be enough cause of the whole Trump administration is blocking non domestic shipments of particular goods like asic miners. I don't know if that's true of all international asics, or just ones that failed FCC regulations.

I've had my miners running almost a month and have had 0 stales, thank goodness. About 200 rejected, 1M rejected, 550k accepted and 5k hardware errors. Difficulty set at 4.5k.
That's just for my S9.

Unfortunately the new updated OS for my other stick miners took away the CGminer status page with all the details.

Interesting. I'll check that out.

When I use the tool it's under 100ms, which seems better. It floats around 85ms-95ms.

I haven't tried any of the other pools. I should look in to that and see if there's any difference.

I've seen a few topics on this and want to check I'm doing it right. Since, I'm lottery mining, I don't want to worsen my changes further with high latency.

First I was using sites I've found on google to check pool latency and comes back with 180ms-190ms.

But I believe now that they are not accurate, I should instead use a tool which I installed one that is a stratum ping tool. I read it pretty much preforms the exact task a miner does to send packets to the pool and returns a ping.

I'm using ckpool, so the pool address I saved to the bat file is exactly "solo.ckpool.org:3333".
That should give me an accurate ping I should be getting for the miners on my network for that pool, right?

I'll have to look in to how to verify for myself if a new wallet is safe. I assume you get them from github.
I haven't taken the time yet to see what one would look like, if the wallets have code that is readable, or if it's all in machine code and you need a tool to convert it to readable form to look for anything malicious.

I do still want to get in to GPU mining too and I think that would be a lot of fun, though now, it's a little more than I can tackle atm. At least now I know to be more aware of security and not just go willy nilly with installing new wallets.
Regardless, I would definitely use a VM and make sure the network won't be compromised.


I still have loftier ideas and haven't given up on mining. I do really hope to have a decent mining farm someday, like after I have a solar system installed. It might take a while.

Oh yes, I do have some small ASICs at home. An S9 and some CompacF's and an R909 miner. Though I have to watch my power consumption which is why I made sure my S9 only uses a few hundred watts.
For now, I'm keeping those running as lotto miners.

I am looking for new coins and I think I know what you mean by the block explorer, I tried to check it out and I think I need to understand how it works.

Though I have a few problems that throws a wrench in my plans to mine in general for now.

One I didn't consider is security when GPU mining, that when mining new coins and installing the core wallet, you run a big risk installing malicious software.
Which is an additional cost of equipment and a learning curve to consider.

The other is my electrical costs are too high to make mining practical, which also ties in to budgeting constraints.

I have plans to move to a new property where I do plan on installing a solar system at the very least.
Hopefully by then it won't be too late for the home miner to get in on the action.

Okay, so I have stuff coming to make my first GPU and CPU mining rig. It's not gonna be anything impressive. So the capability of the rig is not really my top concern. I do intend to mine up to three different coins at the same time for the same duration.

My priority is to diversify, like I have with my other portfolio and has worked well, so I feel to do the some with my crypto holdings.

I'm not trying to chase profits, so the kind of coins I'm after are ICOs/emerging projects. Mine the algorithm(s) for about a month and hold the bags I accumulate long term in hopes one of them will .
I'm to understand about 90% of new coins will become failed/dead projects.

When it comes to the number of coins out there, it's a veritable ocean. I have seen where I can find lists of new coins, like coin market cap, but it would be hard to know which ones to choose.
I'm looking for some advice on how to look for coins to try to mine and tell which ones to avoid.

Well I did it. I ordered my stuff.

I decided to go with my original plan cause I was a little leery about the reliability and quality of the mining case. It looks like a killer deal and it might be fine, but I still have to make a custom rack and it has to fit inside the enclosure I made for a couple reasons. I'm not sure I could trust the equipment in the enclosure and not have something happen, or it craps out after a few months.

Even with the stuff I ordered, I still got one of those automatic fireball extinguishers that I'll install inside the enclosure, just in case.

Yeah, I have that feeling too, I was deciding which was the better choice.

I agree. It's making me feel like I should just go with my original idea. After putting all the parts together, between to two different rigs, there's only a $200 difference and with the first rig, I would feel more confident the parts would be better quality.

Oof. Well that's a little disconcerting.
In that case I'm installing these automatic fire extinguishers next to the unit and a smoke detector near by.

Thought I'm a little uncertain, I think I'm gonna go for it, but I will still be making a custom rack to put all the components in.

Woo! 2400 watts. That's a big one. I'm definitely not gonna push the PSU to that limit. Maybe a few hundred watts at most, at first.

But yes, I installed a 100 amp subpanel just for mining with one 15 amp 240v circuit and one 15 amp 120v circuit. It's only 15 amps cause I only planned on using a small ASIC. And then only using a couple GPUs doesn't pull that much either.

Hrm. Okay, so you mean something that already has all that put together? Like this?

So I've been doing some consideration with what I've been doing with solo mining so far.

I feel I've been overdoing it and spending way too much for something that's meant to be a very inexpensive mining set up.

There was an enclosure I made for my ASIC that was also running as solo miner and now feel it's overkill. Instead I decided to build a GPU mining rig that can also do CPU mining.

There was a build I saw that I liked and wanted to get others opinions on it.

This rig would be a cheap one, I'm okay with buying used parts, on some things, but some I would buy new.
I would also want a robust setup, that the parts are specifically designed for mining so it won't burn out in less than a year. Then also a rig for someone that is starting out and doesn't want get the top of line gear, or have 10 GPUs running at the same time. Here are the components:

Motherboard - Biostar TB360 BTC Pro 2.0 (USED)

CPU for CPU and GPU mining - Intel Core i7 9700k (USED)
or
CPU for GPU mining only - Intel Celeron G5925 (NEW)

CPU water cooler (NEW)

4GB DDR4 Ram (NEW)

Storage - SSD 60GB (NEW)

PSU - CORSAIR RMe Series RM1200e ATX Power Supply, [80 Plus Gold] (NEW)

GPU - x2 INVIDIA CMP 30 HX

OS - HiveOS on Linux

Some of these components are the typical GPUs, or motherboard, but specifically for mining, they are also very inexpensive, available used and will/should last longer than conventional components.

Total cost could be around $600-$800.

What would some thoughts be on this setup?

I finally got someone from Bitcoin Merch to help me out.

What I had to get it to work again was use a USB to ethernet adapter and plug it in to the router. It took about 30 minutes, but eventually my router detected the wired connection and I used that IP.
Thank goodness I already had a adapter on hand.

So from there, because I already flashed the miner with an update, I had an updated Bitcoin Merch interface/OS. It was asking me for my wifi credentials and the miner was running again.

Sort of.

I had to do a tiny bit more fiddling, cause it seemed like it was having a hard time staying a higher hashrate, so I felt there was still something else going on.

So what I found was a bad PSU, cause I read that to be a common issue.

Again, thank goodness I had a spare PSU on hand for the Mars Lander. I bought one thinking it was an 'updated' model, but it was the same one I already had. So I decided to just hang on to it.

So I think the miner got tweaked partly from a bad PSU, but I recall having some weird power outages in my area lately and I noticed right after, my miner wasn't acting normally. That might have done something to the PSU.

So yeah, bad PSU.

Now that I have and updated OS, I can now use the upgraded Compac stick which would also give my miner a boost.
The new Compac A1 stick miner gets up to 500Gh/s, that's double what I get now.

Maybe I could sell my CompacF and trade for the upgraded stick.

It's a shame that's the case, cause it's the most efficient of the S9's. Perhaps I can sell the unit.
I did get a great deal on the S9j.

The other thought is I might reach out to the one person that has modded firmware for the SE that would make the Braiins OS work.

I am trying to get Bitcoinmerch to help me out too, but came to a problem that I think may be my network settings, or the thing needs some replacement parts, but I want to know where the problem is before I just start ordering random parts.

It worked great for almost a year, then I just recently noticed a reduction in hashrate. That made me notice an abnormally high number of hardware errors. With my solo mining rig, I narrowed it down to the Mars Lander. Only just a day ago the hashrate fell to 0.

My first thought what the stick miner in the unit died, but with some swapping of stick miners on a powered USB hub, I found they all worked fine, only when using the Mars Lander, the stick miner shows 0 hashes.

I attempted to reflash the Mars Lander, but I'm stuck where it instructs to open a local ip in a browser.
The ip is specifically to edit the raspberry pi settings. The browser is not loading the local ip.

The best I could come up with is clearing cache, flushing the DNS and whitelisting the local ip on the firewall, but no success.

A quick network troubleshooter reveals that the network is configured correctly, but the local ip in question is not responding. I feel like this could be where it could be dozens of different reasons, but perhaps I can try something else to single out the problem.

I didn't want to, but I went ahead and bought a new miner I got an S9j and is supported by Braiins OS.

Now I'll have to sell my S9 SE.
