Jeri Ellsworth is another good one for electronics.
Up and Atom and TheHappieCat have some good content relating to computer science.
MsMadLemon is good for those into retro computing.
The Signal Path is great for those into RF wizardry.
Knurlgnar24 is unmatched for power inverter teardowns.
M.C. Pletcher and subcooledheatpump are great for DIY refrigeration.
Moving on to more mechanical stuff but very relevant to DIY electronics, there are quite a few nice ladies who'll show you how to do it - 3x3Custom, Anne of All Trades, April Wilkerson, Barb Makes Things, Becky Stern, Blitz City DIY, Darbin Orvar, Estefannie Explains It All, Greylight May, Laura Kampf, Living to DIY with Rachel Metz, Maker Melissa's Lab, Naomi Wu, and The Minimalist Maker.
That's a long list so I suggest starting with Laura Kampf for learning how to make small masterpieces (e.g. project enclosures) with common shop tools.
