Silly Job Title: Electricity Guardian. I am the Electricity Guardian!
In this video we continue working through Learning the Art of Electronics. Today we revisit the differentiator we built last week. We build a new differentiator using a 10 nF capacitor and a 100 Ω resistor. Before we build our circuit we simulate it using EveryCircuit.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signal and generate our 50 kHz sine wave.
We use the METCAL PS-900 Soldering Station for soldering.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Peak Electronic Design Atlas LCR45 LCR Meter to measure our capacitors.
We use the Bysameyee Head-Mounted Magnifier for magnification.
We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to trim our component leads.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Surge Sage. I am the Surge Sage!
In this video we continue working through Learning the Art of Electronics. Today we build a differentiator with a resistor and capacitor and test it with a square wave and a sine wave.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signals and to generate our input waveforms.
We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Switch Switcher. I am the Switch Switcher!
In this video we do the 19th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Radio Station.
We use the LiteVNA 64 Vector Network Analyzer to measure reactance and resistance of our antenna coil.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signal.
We use the METCAL PS-900 Soldering Station to make our cable fixture.
We use the AiXun H314 Hot Air Gun to shrink our heat shrink.
We use the MUIN Solder Fume Extractor to clear the air.
We use the Riden RD6006 Bench Power Supply to provide power.
We use the EEVblog BM2257 Digital Multimeter to measure resistance and check continuity.
We use the Peak Electronic Design Atlas LCR45 LCR Meter to measure capacitance.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to cut, cut, cut.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Solder Soldier. I am the Solder Soldier!
In this video we have a look at what’s in The Art of Electronics: The x-Chapters 2nd Edition by Paul Horowitz and Winfield Hill. The book’s website is here: https://x.artofelectronics.net/
In the same family of books are The Art of Electronics 3rd Edition also by Paul Horowitz and Winfield Hill and Learning the Art of Electronics: A Hands-On Lab Course 2nd Edition by Thomas C. Hayes, David Abrams, and Paul Horowitz.
There were a few things that came up as we flipped through this venerable tome:
- Prehistory of The Art of Electronics
- Metcal PS-900 Soldering Iron
- JBC Soldering
- Four-terminal sensing
- Digital potentiometer
- Highland Technology
- Sziklai pair
- PIN diode
- Audio Power Amplifier Design by Douglas Self
- Eurocard (printed circuit board)
- Building Electro-Optical Systems: Making It All Work by Philip C. D. Hobbs

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 ”F 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.
