Silly Job Title: Plugerinerer. I am the Plugerinerer!
In this video we continue working through Learning the Art of Electronics. Today we build the circuit from Fig-2N.5 which is a simple RC circuit that we charge with a voltage source.
Our charge and discharge curves for the 1000 µF capacitor looked like this:
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signal.
We use the Riden RD6006 Bench Power Supply to provide 10 V for testing.
We use the EEVblog BM2257 Digital Multimeter for continuity testing the switch we use on the breadboard.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

I mentioned about this SMBC comic: your ethical system is nuts, man!
You mentioned about Information is Beautiful.
