Is it possible to make a LED at home? Answered

I want to make a Little LED from scratch


A practical one? Probabaly not. An edible one https://www.instructables.com/id/LED-Lights-Gummy-Candy-Edible-Glowing-candy/ YEP! There was a light bulb someone made from scratch that was cool and possible https://www.instructables.com/id/Homemade-Lightbulb/. You could rig up a bulb and a diode?

This guy here attempted to make OLEDs at home. List of supplies materials etc pretty thorough!
