Like playing the lottery! fun to watch, but more for show. Set up sucked, took forever for it to connect.

Got this for fun. Initially it didn’t even work. I was able to connect to the internet and add my BTC address but it wouldn’t finish the initial setup. Was driving me nuts. I was determined to make it work. Reset it probably about 3 or 4 times. Ended up changing the preset pool because the problem was the one that was preloaded into it didn’t work. I Love that this is pink and matches my desk setup excited to have this cool little miner on my desk that hopefully strikes gold & wins big. Have patience. It does work but because it comes without a manual you have to just kind of tinker with it and figure it out. You can reset it by pressing and holding the top button. Update- After verifying to see if it was actually mining it does not. It's just a toy for show an expensive miniature alarm clock. Definetly Returning. Total Scam. It's a lottery miner that doesn't actually mine anything at all.

No instructions. Comes preset with some unknown BTC wallet address - so, if you do not set that to yours you will never get the reward if it does happen. Had to use trial and error to eventually figure it out. Nice to see the crypto prices on the screen as a monitor. Here is the process to get it working: plug into a USB power port, press the button on the top, change mobile phone wifi to the network name of the miner. The config page loads, there you can set the miner to use your home wifi network with the password, BUT once that is connected, you need to load the real config page by entering the miner's IP address (like: 192.168.1.100) into your browser and then you can edit the BTC wallet address. It is also good to see that it is operating. CAUTION: if you press the button on top of the miner you can inadvertently clear the wifi settings and then you have to do it all over again. It seems to have a mind of it's own. It either changes screens or resets config. I have noticed that if you unplug it and plug it back in, it reboots with its wifi and wallet settings retained.

A little tweaking in the setup, and "BAM", we're off to the races!! I'm learning a good bit playing with these things. They're making me want to build an asic miner to make some real cash.

Can't give a zero review!! First, it was supposed to be next day...a week later.. then the case looked like someone opened it, it literally popped off as i was putting it in the port. I didn't care really, more ventilation. Went through the standard setup process and let it run. Next day, check up online, i see my other 3 miners and not this one. It stalled at 80% loading up. Tried again with a different mining site, same thing. Did this way to many times!! Let it sit overnight unplugged, same thing again. Tried all the reprogramming and update sets, nothing works. Sending back for a replacement, going to give it 1 more try. Not impressed at all!! Bought cheaper ones with better results!

After millions of visits to reedit, chatgpt troubleshooting, shouting at the gateway login in screen for the device, and about 4 gallons of tears I finally figured out how to get this thing to actually work. 1.stratum+tcp://public-pool.io:21496 <----never works, you will get to about 80-86% connection progress and get stuck on pool connection and never connect in. 2. Your wifi info you put in did save even though when you go back to the info section of the gateway page for the device shows nothing. Rule of thumb is that if you make it to a pool connection stage that means it has accepted your wifi info and connected to the internet otherwise you would be able to attempt the pool connection 3.Use the NM ESP Flash tool, to get your computer to recognize the device hold down the little button WHILE you plug it into usb, you will know you did it right because the screen will just show black and a new COM device will show up when you go to update the firmware with the tool, for me it was COM3. 4. Use firmware version 1.1.01, i prefer this version because it wont just say "Pool Connect" for the status and will actually say "Pool Connect <pool name> 5. MOST IMPORTANT USE stratum+tcp://pool.tazmining.ch:33333 it connected instantly for me and is running 100% stable. 6.Dont really pay attention to the provided instructions they are really incorrect. And don't worry about that license nonsense you see either you don't need it just follow my instructions. 7.Don't leave the password field blank in the gateway for the pool use "x" without the quotes and no space before or after 8.Plug it in and let it work Update: So i have come to understand the operations of these devices a little better. I have found out how to get them functionally operating and have mine going with a uptime currently around 32 hours. If you want to view your stats connect to the same network the device, then punch into a web browser the device IP that your screen displays. I just downloaded a the "NM Controller" software that essentially does the same thing except in a program not a webpage. The wepage looks exactly like the one in the images they provided.My ip was like 192.168.1.27 or something like that, it will be a diffrent ip then the one you used at the wifi configuration page incase you cant read the screen. On a final note, you dont have to use the tazming pool either just search on google for a "Lotto Miner Pool" i switched my pool to stratum+tcp://ss.antminer.com:3343 or port 3333 I THINK just look it up and see what you like. Also ask chatgpt for recommended pools as it was a life saver because im well versed in python but C is a lanuage as ancient as sumarian culture thats annoying. Oh also, if you want to make your own antminer it's super duper easy just buy a esp32-s3 and you can essentially use the firmware tool website to dump on the info. Personally i had chatgpt write up a firmware thats custom with my own wificonfig page and coded to be pinned out for a esp32-s3 and had it put in some coding for a ssd1306 display to show the same kind of information on the device. Just tell it to be sure to add the "stratum protocols" for mining which is just basically the part on how in connects to the pool and such. After that check your new webserver and screen. Depending in your pool aswell you might be able to hop on their website and see all the miners currently in the same pool and your device name should popup or wallet or matching stats. Its kind of neat to verify its actually working that way. Cheers prospectors!

Woooo this is tiny! Great to have on your desk. What’s interesting is that it seems to out perform my larger nerdminers! It was easy to set up. The price was great. Would recommend at least one

Without any instructions, there’s no way to tell if the thing is working or not, and with the odds of actually winning being so astronomical, there’s no way for me to give it a good rating
