avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.
As far as I could see, you miss a connection from Arduino pin 10 to Attiny reset
1) Just connecting arduino uno and pressing Upload sketch button

Do all the wires conduct electricity?
I had some trouble with the capacitor not connecting properly when plugged directly in the headers of the board. Moving it to the breadboard solved the problem.
2) Connecting arduino uno, holding reset and just when "Binary sketch..." shows in the console I let the reset go.
The two methods return different errors (at least in the video but i'm trying to reproduce it right now with no success).
