Please mention good online video lectures on theoretical foundations and practical implementation of DFT.
Thomas has listed some great resources. Let me add some more, mostly materials science-related ones:
NOMAD has regular workshops, "Hands-on DFT and beyond", and the recordings from 2017, Berlin are uploaded to Youtube: https://www.youtube.com/playlist?list=PLbgFiRV2JFy-VQ3D6cJjn5jkXmAsjQPiT Slides of the more recent workshops can be found

- Peking (2018): https://th.fhi-berlin.mpg.de/sitesub/meetings/dft-workshop-2018/index.php?n=Meeting.Program
Kieron Burke has several good links on his lab page, including a CECAM lecture series from 2017, "Teaching the Theory in Density Functional Theory" (https://www.youtube.com/channel/UCfLssAro7SMxgaeKTNFFeeA/feed)

All content is offered via prerecorded videos. Each video comes with a task, and after submitting the task there is in many cases either automated feedback or peer feedback. At any other time of the year, you can still study this course in a self-paced way. There is the opportunity to be part of a team to work on a project. The course is free of cost and open to anyone. Emphasis is on conceptual understanding and hands-on training, not on mathematical theory.
2. An Introduction to Density Functional Theory for Experimentalists by Prof. Feliciano Giustino during DFT Summer School 2018 at Cornell University
The goal of this Summer School is to introduce experimentalists to density-functional theory calculations and first-principles materials modelling. This course answers the basic questions: “Can DFT help me with my experimental problem? Which materials properties can be predicted and how reliable are the results? How difficult would it be to run the calculation that I need? Can I do this on my own or I better seek for help from the theory group next door?”. By the end of the school the participants will be able to perform basic DFT calculations in complete autonomy, and will have a better understanding of the current literature on atomistic modelling using DFT. The course is articulated along three parallel tracks: theory lectures, practical lectures, and hands-on sessions.
I have found some interesting lectures about DFT in general that could be useful for you:
