To get more comfortable with electronics, we decided to spend a couple of weeks deep diving into some foundations of electronics. Some of the topics we covered as a part of this included:

1. Soldering and desoldering test circuits
2. Testing with a multimeter
3. Circuit analysis
4. Circuit design printing - Laser PCB and CNC PCB

Soldering and desoldering test circuits

Materials required for desoldering and soldering

• Soldering iron

• Soldering paste (to keep the soldering iron clean)

• Sanding paper (to keep the soldering iron clean)

• Solder filament

• Helping hand (to support the board while desoldering and soldering)

• Pliers

Some interesting electrical parts I came across while working on this exercise
