Silly Job Title: Outlet Overlord. I am the Outlet Overlord!

In this video we continue working through Learning the Art of Electronics. Today we build a C:C voltage divider with two capacitors after reviewing our notes for 2N RC Circuits so far.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to generate our test signal and examine our waveforms.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Silly Job Title: Wattage Warlock. I am the Wattage Warlock!

In this video we continue working through Learning the Art of Electronics. Today we build a voltage integrator
with a resistor and capacitor. There is an EveryCircuit simulation circuit over here: LAoE Fig-2N-12-B Voltage Integrator.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to measure our input and output signals.

We use the Sharp EL-546L Scientific Calculator for calculations.

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.

Using a 1 kΩ resistor and 1 µF capacitor we fed in a 1 kHz square wave:

1 kHz square wave input

And a 1 kHz sine wave:

In this video we do the 20th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Wireless Rain Detector.

In this video I mention about my copy of Silicon Chip magazine which arrived today, check them out!

We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signals.

We use the EEVblog BM2257 Digital Multimeter to debug the power circuit.

We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.

Silly Job Title: Master Planner. I am the Master Planner!

In this video we unbox our TI-36X Pro scientific calculator from Texas Instruments.

The books I mention are TI-36X Pro Scientific Calculator Practice Examples and Calculus on the TI-36X Pro Calculator. These books are low quality (lots of errors and omissions) but they’re still useful.

The manual is here: TI-36X-PRO-Guidebook_EN.pdf.

The QR code on the insert goes here: https://education.ti.com/en/select-country/eguides

There’s more information on the Texas Instruments website: TI-36X Pro scientific calculator.

This is the box:

Silly Job Title: Component Wrangler. I am the Component Wrangler!

In this video we continue working through Learning the Art of Electronics. Today we build a current integrator with a capacitor. Before we build our circuit we simulate it using EveryCircuit: LAoE Fig-2N-12-A Current Integrator.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our waveforms.

We use the METCAL PS-900 Soldering Station for soldering.

We use the MUIN Solder Fume Extractor to clear the air.

We use the Riden RD6006 Bench Power Supply for constant current.

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 component leads.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

Less-Common Features of Multimeters

Some interesting features.

His old Fluke 187 meter has a “nS” mode (nano-siemens) which can give crazy high resistance measurements (up to 100 GΩ) as conductance measurements.

His Fluke 87V has a low pass filter on its AC voltage input.

He explains Lo-Z mode and phantom voltage. It works by putting a thermistor across the input leads.

His old Tekpower TP8250 analog meter has a D.Ω range for measuring low resistances and a NULL mode for indicating voltage direction. His Sanwa EM7000 also has a NULL mode facility.

His Tekpower TP8250 also has a battery mode, which will measure the voltage from a battery with a load attached.

His ANENG AN870 has a Non-Contact Voltage sensing (NCV) mode which does what it says on the tin. My NCV device is a Fluke 1AC-C2-II VoltAlert Voltage Detector.

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: LAoE Fig-2N-7 Differentiator with 50 kHz Sine Input.

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.
