Here is one of the electronic ones that I am using for a big lamp in my dining room:

Your general approach is reasonable, but your power supply selection might be a problem.

The simplest thing to describe and to understand is to simply run the 10-3 back to your breaker box.

If you want to try to run from that junction box, you will need to determine just what is in...

Just a slight clarification: You are only allowed to round up on the breaker size if the calculated load on the conductor is less than the conductor ampacity. Your conductors are rated for 85A. ...

For your application, a higher wattage transformer couldn't hurt.

The site that you linked showed 240V to 120V transformers, which are the wrong voltage to do the job. These also may be...

The 'old' dimmers that actually dropped the voltage were either variable resistors, or they were variacs. You are already going down that path.
