You can only be "involved in" an event; use "involved with" here instead. I would also use "anything" instead of "everything". Everything means all the things, anything means any of the things, but not necessarily all the things. When you're talking about a broad category like this, it's almost impossible for it to actually be everything, so anything is more accurate.
I'm interested in anything regarding technology.
I'm interested in anything involved with technology.
I'm interested in anything to do with technology.
I'm interested in anything related to technology.
Technology interests me.
All technology interests me.
Example of "involved in" (the one I told you not to use here):
I was involved in a crime.
He was involved in the cooking at the barbecue.
Will you be involved in the school play next week?
<em>All of these are events or situations.</em>
