Is there a good tutorial out there on how to set up an Electrum server to use with a Sparrow wallet? There's a guide on the Sparrow website for setting up a server with ElectrumX, but I'm wondering whether that's the best option? Is there any reason to use ElectrumX instead of other options like Electrum-Server or Electrs?
Another question I have (which I don't see answered on Sparrow site) is whether it's advisable to run the Electrum server on the same laptop that Sparrow (and Bitcoin full node) is running on. I remember reading somewhere (forget where) that doing that can cause security/privacy issues and it's better to run Electrum server on separate hardware. Is this the case?

Today I tried to download Sparrow Wallet again and the speed was improved but there were limits on download. There is definitely a problem on their side. I'll try to contact them and let them know about this issue.
If you are the only one reporting this problem than issue can't be on their side.Download is working fine for me, and it's not the first time I did that, but you can always use alternative option and download Sparrow from their official github page:

Maybe you experienced some temporary or local Github connectivity issues. And nobody except you can know what's going on in your local network.
20min for the download of ~100MB doesn't sound any fast either, but Eleutheria didn't mention any details of personal internet connection. Such a download time could happen when you only have something like 1MBit/s downstream.

I tried download it just now, but it use my maximum internet speed. It's likely their server was overloaded, although there's small chance your ISP throttle your connection. Next time you experience this problem, you might want to use VPN and see whether you still experience slow download speed.
Now the problem is that it takes almost one day to download the wallet while filesize is up to 98 MB. For some reasons, their servers don't let me to download it with normal internet speed and limit my download speed significantly.
I just downloaded it now and it took roughly 20 minutes to download with my personal internet connection. I do not think it is their server limiting your download speed and surely not intentionally. Could be an overload on available connections on the web server or some other reason. Try clearing your cache and try again.
I finally managed to download it in one hour instead of a day. Thanks god, speed improved a little.

Since this thread looks like an ANN thread of Sparrow Wallet, I'll ask this question here instead of creating a new topic.
I want to download Sparrow Bitcoin Wallet from sparrowwallet.com/download for Windows. I choose the following wallet ->> Type Windows Installer (7+); Link Sparrow-1.8.4.exe <-- Now the problem is that it takes almost one day to download the wallet while filesize is up to 98 MB. For some reasons, their servers don't let me to download it with normal internet speed and limit my download speed significantly. Does anyone know where is a good alternative to download this wallet? Or do you also experience download limit from Sparrow? I have no idea why that happens.

You mean, despite that I already connected my Sparrow wallet to my Bitcoin Core node, I still have to have the Ronin Dojo node running to use Whirlpool Coinjoin anonymously?
I never had Ronin Dojo node running, and I don't have any plan for doing that, so I can't tell you anything more about that.My understanding is that nobody can obtain any information if you are using whirlpool correctly with Sparrow and enabled Tor, but I can't personally vouch for that.
It's relative to specific situation but Ronin Dojo is your own backend replacement for servers, so if only you are using Dojo in mixing round than privacy will obviously not exist.
You can participate in in Whirlpool only if you run full node with Ronin Dojo node package.
Sparrow is using same pools like Samourai wallet, they are just another client, and I would always choose Wasabi coinjoins rather than what Samourai is doing, but you can find detailed instructions on sparrow website.
I would wait for Wasabi 2.0 to come out soon, it should be more simple to use and I here some great improvements are coming, like reducing 0.1 BTC minimum.

You mean, despite that I already connected my Sparrow wallet to my Bitcoin Core node, I still have to have the Ronin Dojo node running to use Whirlpool Coinjoin anonymously? What if I don't have Ronin Dojo? I heard that, in Samourai Wallet, if you are not running one, all the information about transactions and addresses goes directly to Samourai servers, which means they can deanonymize you if they want. However, in the article, it is said that "Sparrow does not ever use Samourai’s servers to provide wallet transactions or UTXO information. This information comes from your connected server, as it has always done. Only the independent Whirlpool server receives communication, and the data it receives is blinded so no privacy is lost when using Tor." I don't understand how in this case Samourai devs can obtain information about my transactions?
Assume I installed my personal bitcoin full node through Bitcoin Core wallet and connected my Sparrow wallet directly to it. Is that the right direction or am I supposed to connect my wallet to a public server instead?

How do I properly configure my bitcoin full node? What further steps should I take to achieve maximum anonymity?
There are many guides for running full Bitcoin node and it's nothing complicated, all you need is to have separate computer of RaspberryPi with hard drive, than you download entire Bitcoin blockchain, and let it run.
Mixing with Whirlpool
This article by Samourai Wallet discusses Whirlpool CoinJoins:
Diving head first into Whirlpool Anonymity Sets
Unfortunately, I don't use this particular wallet and can't provide more precise information. Maybe these resources are a good start.
After the developers of Sparrow Bitcoin wallet have finally implemented Whirlpool, which is another way to CoinJoin bitcoin transactions, I decided to try it out. The question is how do I do mixing without leaking unnecessary information that may further be used to deanonymize me or to connect my identity to transactions I make in the bitcoin network. Assume I installed my personal bitcoin full node through Bitcoin Core wallet and connected my Sparrow wallet directly to it. Is that the right direction or am I supposed to connect my wallet to a public server instead? How do I properly configure my bitcoin full node? What further steps should I take to achieve maximum anonymity? I want to use Sparrow wallet in the most effective way possible...
It was recently confirmed that Chainalysis runs public servers. Is it bad? We bitcoiners have known that this has always been possible.
We knew it was happening and I bet that government agencies are also running a bunch of nodes and servers for years, same way like they are using Tor and everything else for spying people.It's not so hard or expensive to run your own node on some old computer or Raspberry Pi device.
There's not even one reason if you want to make transactions with it.
You can have your old coins in legacy address format (like there are a bunch of them) and that is a valid reason to use them to send and make new transaction with them.Please let's all keep to the topic subject - Sparrow Bitcoin Wallet.
Thanks
That's so true:
There's only ONE exception why one would prefer on using a legacy address and that's the signature verification part. Apparently, verifying a message which was signed using a SegWit address isn't standard. Each software implements a different way.
So if you ever wanted to sign a message which could be verified even from an abandoned project-site such as brainwallet you should use a legacy address.
There's not even one reason if you want to make transactions with it.
Although, it doesn't make much sense using legacy wallets and addresses nowadays

I was able to create an Electrum wallet with legacy addresses, which I thought was impossible. Thank you for that.
No problem, you are welcome. Although, it doesn't make much sense using legacy wallets and addresses nowadays, but I understand that you want the ability to create those if you wanted that. A significant number of crypto-related services should already be configured to recognize native segwit addresses, and if they don't, there is compatibility with nested segwit addresses in over 90% of the cases. 
You can, but not in a standard way.
Dude, you rock!! I was able to create an Electrum wallet with legacy addresses, which I thought was impossible. Thank you for that.I'm still liking the Sparrow wallet, by the way. I don't exactly have a need for another wallet, and I like Electrum a little bit better, but I'm not going to discard it like I have with so many other wallets I've tried (like Exodus, Coinomi, and a bunch of others).
RaspberryPi and a 1TB drive and your good.
I've got the former but not the latter--at least not unoccupied at the moment. But I appreciate the suggestion very much. 
I love their initial setup with explanations and easy process for users of choosing connection with bitcoin core node, private electrum node or public server.
OK, that part confused me a little bit since Electrum, for instance, doesn't make you choose a server (although you could if you wanted to). I didn't play around with the wallet since creating it, so I'm not sure how the bitcoin core node works. That's the one I selected initially, but it doesn't connect. When I selected the public server, all was good except I got the warning message "Using a public server means it can see your transactions."How bad is it that my transactions can be seen on a public server?
Edit:
Why don’t you run your personal server for electrum. That would be quite handy to keep your things private and secured.
Because I'm a dumbass and haven't learned how to do it and why it's important to do. You'd think I'd have learned more about the technical aspects of bitcoin by now, but nope. I pick up dribs and drabs as time goes on. I didn't even know what a GPU was until about a year ago.It was recently confirmed that Chainalysis runs public servers. Is it bad?

raspiblitz https://github.com/rootzoll/raspiblitz has ElectRS as a 1 click install to setup your own electrum server
mynode https://www.mynodebtc.com/ has one too
RaspberryPi and a 1TB drive and your good.
If you don't want to do that mynode has a virtual machine download so you can run it on your PC using VirtualBox if you want.
Even if it does not work for you for what you want to do it's still a good learning experience.

I was able to create a wallet with legacy addresses, which you can't do with Electrum anymore, so that's a plus.
You can, but not in a standard way. You have to first enable the console tab by clicking on 'View' and 'Show Console'. Enter the following code in the console tab:Code:
make_seed(128,"","standard")
Here is an example of how it looks. For some reason, I had to do it twice because nothing happened the first time.
