here is the complete article. this author does not give part numbers of the components to build project.
As they are adding a plastic washer to set a core gap, it's apparently an ungapped core, so the one with the higher AL value in the suppliers listings.

The plastic washer reduces that to an appropriate level.

This appears to be an appropriate one (a pair of cores):

And the coil former to go with those:

The N48 material also seems OK.

Most manufacturers of switchmode power supply transformers/inductors will be happy to help you with selecting magnetics parts for this or any other step-up (boost) converter. The given circuit is actually pretty simple, and you can use a variable resistance instead of the multiposition switch.
