A hand tool used to melt solder, which is a fusible metal alloy used to create a permanent bond between pieces of metal
Strangely enough, that's the technical term for this desoldering vacuum tool. Useful in cleaning up mistakes, every electrical engineer has one of these on their desk.
To use, depress the end to engage the vacuum. Then heat up the to-be-desoldered joint until it is liquid. With your other hand hold the plastic tip as close as possible to the joint and depress the button to suck up all the liquid solder. If necessary, clean up the remaining solder with wick.
A mini-vise for working on smaller Printed Circuit Boards (PCBs) (2.875" or less in one dimension)! The jaws are strong plastic that wont damage the PCB and doesn't mind if you hit it with the soldering iron by accident.

Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor’s resistance limits the flow of electrons through a circuit.

What makes capacitors special is their ability to store energy; they’re like a fully charged electric battery. Common applications include local energy storage and voltage spike suppression.
DC v AC applications
Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.
Rather than oscillating back and forth, DC provides a constant voltage or current.

The key function of an ideal diode is to control the direction of current-flow. Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They’re like the one-way valve of electronics.
Force Sensitive Resistors (FSRs) are sensors that allow you to detect physical pressure, squeezing and weight
