Overview
The current sink or swim is a self-powered current sink for testing devices like batteries, power supplies and more. Potentiometers give individual current and voltage control. A jumper allows external power (instead of “self power”) for applications where the current source does not have sufficient voltage.
Prerequisites
- You should have understand how to use KiCad. Check out the following courses:
- Hardware required
- Soldering equipment
Learning Objectives
- Create a current sink for your bench, to be used in future projects
- Understand analog control, using operational amplifiers (op amps)
- Measure and revise analog circuits
