She has a great YouTube channel as well! I got turned onto her channel when Dave Jones of the EEVBlog and a group of other EE youtubers were passing around a circuit from one of the Apollo missions. https://youtu.be/J0ggqY7vnAw
Fran's videos are some of the most interesting out there, while managing to be very relaxing as well. Couldn't recommend them more.
She's like a much, much calmer version of Dave Jones. I'm glad I found this!
For all the Commodore 64 fans out there, she has a nice introductory video.
