You can create any arbitrary address simply by putting the correct checksum at the end. You, of course, will not know the secret key, so anything that is sent there ~~is unlikely to ever be received~~ will be destroyed and can never be spent.

FIFY.

Here is an example I made a long time ago:

Code:

11When1DieBuryMeDeepLayTwoXVEY5jv - (Unspent) 0.00000001 BTC
11SpeakersAtMyFeetAPairofXXTyrHor - (Unspent) 0.00000001 BTC
11HeadphonesonMyHeadAndXXXXYUSvnd - (Unspent) 0.00000001 BTC
11ALwaysPLayTheGratefuLDeadWdq4Xo - (Unspent) 0.00000001 BTC

How do you add a check sum? Might come in handy later.

1) create a template of your desired address ie 1waLLobserverburnaddressxxxxxxxxx ^{(the last few characters will eventually be random due to checksum)}

2) Base58 unencode your burn address into hex - 000A52498DB787B09EEC7C428B8B0C853EA1C2702C4E117611

3) remove the last 4 bytes from the result and call what's left N - 000A52498DB787B09EEC7C428B8B0C853EA1C2702C4E117611

4) sha256(sha256(N)) - BD0F89693417148626446F3E1EA43A69453FBCF72A024600FB54A2BC34F23387

5) take the first 4 bytes of step 4 and stick it on the end of N - 000A52498DB787B09EEC7C428B8B0C853EA1C2702CBD0F8969

6) base58 encode step 5 - 1waLLobserverburnaddressxxy1oWwkk

done

Is there a step missing between 4 and 5?

And as I understand, sha256(sha256(N)) would simply mean "hashing a hash" - correct?

000A52498DB787B09EEC7C428B8B0C853EA1C2702C (from step 3) sha256'd is:
414852558A27373137680508E28F0C3E35481EF766D72CDDFA27084EECBFFAA3
... and when this ^ is sha256'd I get:
3649A20CD93B0A51FDFFF9831E8DC4EBB9FE0883708D2969E79E70AE78FF51B1

Where does BD0F8969 come from in step 4, in this example?

I used this site to hash: https://passwordsgenerator.net/sha256-hash-generator/

You have to use the binary data rather than the string value. Probably the tool you are using doesn't convert the string to a hex number so it will use the ASCII code for each character in the string as input.

Try this site - https://anyhash.com/sha256 and make sure to select the hex checkbox to the right.

1YesThatWorksThankYouXhomervUVfQs!

I used the site you suggested for sha256, and this site for base58:
http://lenschulwitz.com/base58

Obvious, but just to be clear, this is only useful for anyone needing a burner address - you cannot generate the private key.
