No, but direct me to some instructions (or provide them here) and I'll check it out!
Here's a brief synopsis from the perspective of Hinduism.
"Samadhi is oneness with the object of meditation. There is no distinction between act of meditation and the object of meditation. Samadhi is of two kinds,
[49][web 5] with and without support of an object of meditation:
[web 6]
The first two, deliberation and reflection, form the basis of the various types of
samapatti:
[53][55]
- Savitarka, "deliberative":[53][note 17] The citta is concentrated upon a gross object of meditation,[web 6] an object with a manifest appearance that is perceptible to our senses,[56] such as a flame of a lamp, the tip of the nose, or the image of a deity.[citation needed] Conceptualization (vikalpa) still takes place, in the form of perception, the word and the knowledge of the object of meditation.[53] When the deliberation is ended this is called nirvitaka samadhi.[57][note 18]
- Savichara, "reflective":[56] the citta is concentrated upon a subtle object of meditation,[web 6][56] which is not perceptible to the senses, but arrived at through inference,[56] such as the senses, the process of cognition, the mind, the I-am-ness,[note 19] the chakras, the inner-breath (prana), the nadis, the intellect (buddhi).[56] The stilling of reflection is called nirvichara samapatti.[56][note 20]
The last two associations,
sananda samadhi and
sasmita, are respectively a state of meditation, and an object of
savichara samadhi:

There are also other dharmic religions' perspectives in that article.
I'll see what else I can dig up in a bit, and later when I have a bit more time, I'll post my own process.
ETA: I would advise you to steer clear of the YouTube videos on samadhi. I found them to be quite useless.
As promised, a process that has worked for me. My flavor tends more toward asamprajnata, meditation without an object. However, in order to achieve this, I have used objects in my consciousness, and through the expression of neti-neti, have realized oneness with with them by way of realizing I am not them (yes, I understand that is seemingly contradictory, but the concept is difficult to express with words).
______________________________________________________________________________
Place yourself in a comfortable meditative posture. Close your eyes.
Bring your attention to your body. Open your senses. Flavors in the mouth, any odors in the air, the touch of the temperature of air on your skin and the clothes touching your body. Sounds you hear, both nearby and distant. With your eyes still closed focus on a point just beyond your nose.
Begin with each sense organ and realize you can observe what each one senses and that these smells, tastes, feelings on the skin, and sounds are not you.
Then move to each sense organ itself. With your mind, you can observe each one, the mouth, the ears, the nose, the skin and the eyes, and realize that since you can observe them, they are not you.
Then bring your attention to the breath, the rise and fall of your chest with each breath. You can observe the rising and falling and the breath itself. Since you can observe them, they are not you.
Turn your attention inward to your thoughts in your mind. These thoughts come and go, and are thereby temporary, whereas you, the observer of these thoughts, are permanent. Since you can observe these thoughts, they are not you.
Ask yourself, "Who am I?" Who is it that observes the objects of the sense organs, the sense organs themselves, the breath, the thoughts in your mind, or the mind itself? You realize you are not your body, you are not your mind, you are not your thoughts, your perceptions, your judgments, or your ego. You are pure consciousness. Exist in that state of being, a state without thought or judgment. Stay with this as long as you are able.

I used this process for some time until I eventually was able to achieve this state of being without the process. But in times of stress when I find myself slip back into a state of avidya (ignorance), I do, until this day, find this exercise useful.
