Take note there is a warning on SourceForge that TrueCrypt has a security issue meaning it's not a secured virtual disk check the warning below.


So even if you move your wallet there and turn it offline if you are using your PC online there is still a possibility it would compromise your wallet so better move the wallet to another PC/Laptop which is completely offline.

Honestly, I don't have a source it only came to my mind because maybe they are similar to S9 Chips that have 135 max temps.

However, I recently realized after checking the Skot project called Bitaxe that the max temp shouldn't be more than 90c my reference is the temp he share on his Twitter, The PCB temp and the Braiins auto mode dangerous temp.
I couldn't find any data so this is just my own guess collected from other user's posts.

Sometimes the ISP/router is the cause of this problem due to the firewall you might need to disable the firewall of your router to fix this issue if not then try to use a VPN or if you already using VPN try to turn off VPN and try again.
If it still doesn't work try to change your PC DNS(Google or Cloudflare DNS) and try again.

You have a similar issue on Electrum Github posted years ago you can read them here "The server returned an error when broadcasting the transaction"

If all suggestions do not work you can broadcast the transaction manually to do that you need to copy the raw/hex transaction from your Electrum wallet and broadcast them to any PushTX site listed from the link below

- https://en.bitcoin.it/wiki/Transaction_broadcasting

Yes because the security patch of Windows 7 is outdated and ended support by Microsoft 3 years ago and Electrum's latest version no longer supports Windows 7 since the release of version 4.2.0.
It's not safe if you stay using Windows 7 so to ensure you are safe use the latest Electrum and better upgrade to Windows 10 and follow all suggestions from the OP.

If you just doing it for fun while giving service to someone who hires you then you're so kind.

If you are looking for a job or business that looking for someone who can promote or advertise their business why not try the services section you can maybe find someone there who can hire your service. Check the section below and create a new thread that includes your service

Yeah, I agree but if you generated or pick custom words on an infected and online device with your extended word there is still a possibility that someone can steal your seed and extended word.

So I suggest do it on the offline environment you can install Electrum to the offline device and generate a seed there(or pick your own 12 words but make sure to enable BIP39) with an extended custom word and then add a passphrase and tick encryption. Once it's done Electrum generates an encrypted and password-protected wallet file that you can later transfer to the online device only if you want to use it on an online device it is way more safer from keyloggers than doing it all on an online device or completely use it on an offline device and use it only for signing transaction.

It seems Sparrow wallet detects that you are using the same wallet which is why you get the self-transfer warning you might need to separate them according to this link below you can separate them with different sets of configs.

- https://sparrowwallet.com/docs/faq.html#where-does-sparrow-store-data

I suggest check the sparrow.log you can find it under the sparrow home folder or by going to the Help > Show Log File. You should see on the logs why this warning popup

Would you mind to try this below if you are Windows

- Uninstall the ledger live again
- Goto program and files then delete the ledger live folder
- Go to appdata and delete the ledger folder
- Press the Windows+R key on the keyboard and type this %temp% then enter
- Delete all files from that folder
- Restart the PC and try to open it again.

You can also follow the guide from Ledger on how to fully uninstall Ledger Live here https://support.ledger.com/hc/en-us/articles/7643373623453-How-to-fully-uninstall-Ledger-Live-?docs=true

If it still crashing try to use another PC/Laptop and install the ledger live there to test if it is just your PC or your ledger device.

When using listen=1 you are likely exposing your IP to someone who wants to connect to your node and there is a potential risk on listen=1 without using TOR or hidden service malicious nodes/attackers can attempt to exploit something in your node.
Since it reveals your IP to someone you already compromise your privacy and it consumes much CPU and memory.

However, if you want to participate on the network you can leave it enabled but make sure to enable Tor service to avoid malicious attacks.

If you don't have the knowledge to promote your own project then try to learn SEO on-page or off-page SEO its free traffic comes from the SERP.
Actually, without money you can't get more exposure you will need to hire experts or a campaign manager to promote your project.

And honestly, what I see from your token it is a churn and burn or meme token that usually dies fast.

Opppsss.... that was my mistake I didn't review the previous logs I thought that I saw it on the image but the image only shows that the first hashboard is abnormal.


You might did it wrong that is why the version didn't change and sometimes fake SD card have fake voluke that can turn some files corrupted so try to re place a SD card.

Also there is a detailed guide on how to flash this unit through OTG/SD card check this link below

If still didn't work then like other said and my previous post boot it with Braiins OS you can che the guide below how to boot or flash the miner with Braiins.

- https://docs.braiins.com/os/plus-en/Setup/1_quickstart.html#install-braiins-os

How about doing it manually instead of using the CLI tool to generate a key pair?
Have you heard that you can generate a key pair by using a coin?

If not, then it should be the best where you can randomly generate a unique private key from Coin Flipping.

We have a guide on the forum on how to do that check this link below

- https://bitcointalk.org/index.php?topic=3222335.0

Once you've done generating a binary convert it to a hex and then use the bitaddress as suggested above and run it offline and convert the hex to the Wif key and public key.

WIF key should be supported to any wallet like Bitcoin core or Electrum.

Yes he did that was my suggestion on my previous post to know if the cable is damaged or the hashboard is dead.



I don't see any strange logs except on the abandon mix board and 0 ASIC on the 3rd hashboard.
If we see these logs like the Abadon mix board the first thing that comes to my mind like Philipma1957 said that 3rd hashboard might be a replacement board which is why it stop mining due to the EEPROM compatibility issue.

About the OTG SanDisk, that thing might work but I'm not sure if the s19j pro USB port support USB 3.0 and it's a bit expensive why not just buy a Micro USB port to USB female connector which is cheaper if you already have a USB flash drive.

The issue from logs still the same as from your previous logs removing the 3rd hashboard and keeping the two hashboards should run normally with decrease hashrate.

As suggested by mikeywith you can try Braiins OS to test if it is just an EEPROM issue but the problem is as you said before that it does not have the SD card slot have you checked the control board inside and maybe the SD card slot is hiding near Ethernet socket or beaglebone ?
Or if does not have an SD slot then your last hope is to use an OTG drive to micro USB to boot Braiins OS in your unit.

Why not use a P2P exchange that doesn't require KYC? You can easily find someone there who sells USDT without giving ID and a selfie.
Check this tool below

- https://kycnot.me/

Or if you looking for a well-known P2P exchange where you can buy USDT you can check https://bisq.network/
Optional if you also want to buy BTC or XMR you can use Agora Desk check their official thread here AgoraDesk.com | Buy ♻️ Sell Bitcoins Anonymously!

I think you talking about KMS**** to spoof or to activate your Windows 10 which is an illegal tool and could also have some adware or malware. I've tried that thing on my old Laptop I notice some added software on Task Manager after using that tool and every time I restart the Laptop it also runs in the background which I think may be software that monitors all my activity.

Be very careful if you still using this PC with patch activation and maybe they are waiting for a huge transaction before they are going to attack your PC actually, you can use Windows 10 without activating it but have limited features however, it is still safer than patched Activation.

Transferring Neo token to another wallet or exchange always requires a Gas fee but if you stake Neo you can claim free gas that you can use to transfer Neo to another wallet/exchange.
Atomic Wallet has a guide on how to claim a free gas check this link below.

Such a nice project I'd like to have them but still it depends on the price of this unit and it depends on the specs like how much power this miner can consume (it looks the same as Compac F that can be consumed around 15w).


I like the dashboard the design is very simple and since you said you can connect through wifi and it doesn't need Raspi because the board is Arduino then that's a big advantage compared to Compact F.
So for me, I like it but I don't know if I can afford it that is why like I said it depends on the price of your miner.

It seems the idea comes from Duino mining from Gunther where you can mine Duco?

Are you based in Thailand or your business location is in Thailand?
It's weird because you are using .us Domain.

Another is I can't find where to sell hashrate and it is more likely a cloud mining site we know that almost 99% of them are scams.
Do you have any proof of running machines from your data center?

I think yes if it does not have Ethernet socket then it requires control box/Raspberry pi and auc3.
However, base on the old guide from this link below it is already have a built-in controller so you don't need them in order to communicate to the unit unlike old models like 721, 741, 761, 821 and 841 that requires both auc3 and control box.
