We use the METCAL PS-900 Soldering Station for soldering.
We use the Fluke 17B+ Digital Multimeter to test the AC power output.
We use the Horusdy Soldering Station with Hot Air Gun to shrink our heat shrink.
We use the Bosch IXO VI Electric Screwdriver to install our screws.
We use the Brother P-Touch D210 Label Maker to make labels for our project box.
We use the Scotch Titanium Scissors to cut open various baggies.
We use the Carpenter Mechanical Pencil to mark out where we will cut or drill.
We use the Hakko CHP 3C-SA Precision Tweezers to work with our small M2 nuts and bolts and other things.

In this video we have a look at an old book, the Student Manual for the Art of Electronics (find on archive.org). This old book references The Art of Electronics 2ed, but The Art of Electronics is up to 3ed now. In this video we just flip through the book to see what is inside.
This book is made obsolete by Learning the Art of Electronics 2ed, which is an ongoing project of ours.
