Reading time: 2 minutes
I just started reading the book Homemade Robots by Randy Sarafan. On page 165, there is a table of the bare minimum parts needed to complete any project in the book, but AFAICT he has no website with clickable links to those parts. Here are links to the products on Amazon, DigiKey, and Mouser.

NOTE from the book: Some of these parts may become discontinued or the part numbers may change (particularly at Amazon). On these sites, you can simply search for the name of the part itself.
NOTE: These links are not endorsements; I just wanted an easier way to get started, and since I’m manually typing in each product ID, I thought I’d share my efforts.
NOTE: I did my best to accurately reproduce the information from the table in the book. If you spot any errors, please let me know.
