Help with Thevenin equivalent circuit

I was doing some prep work for the upcoming LAoE video and learning about Thevenin equivalent circuits, something I need to understand better than I do, particularly how to calculate Vth and Rth. I built the circuit on my bench, but then got readings I didn’t understand, so I asked about it over on the EEVblog Forum: Help with Thevenin equivalent circuit. In the end it turned out that my initial readings were wrong for some unknown reason, but when I repeated them they came out right the second time…

Silly Job Title: Note Taker. I am the Note Taker!

In this video we make some power cables for use with my FNIRSI SG-002 Signal Generator. I use these as a current source in my experiments. The power cables I required are DC barrel female sockets into banana jacks.

I am getting ready to build some circuits to test Thevenin equivalent circuits which I am learning more about over here: Thevenin & Norton practice problems.

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

We use the AiXun H314 Hot Air Gun to shrink the heat shrink.

We use the EEVblog BM2257 Digital Multimeter to test the cables.

We use the Multicomp Pro MP701033 Resistor Decade Box to explain how I plan to use these new cables.

We use the Plato Model 170 Wire Cutter to cut the cables.

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

p.s. today I added Thevenin, METCAL, AiXun, and Multicomp to my spell check.

Silly Job Title: Transistor Troubadour. I am the Transistor Troubadour!

In this video we do the 11th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Beacon Light.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to examine the waveform.

We use the UNI-T UTi260B Thermal Imager to check the thermals (there wasn’t much to see).

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

Silly Job Title: Spark Slinger. I am the Spark Slinger!

In this video we continue to work our way through Learning the Art of Electronics. In this video we finish 1L Lab: DC Circuits by learning how to use our oscilloscope and function generator.

We use the Rigol MSO5074 Mixed Signal Oscilloscope as our oscilloscope and we use the UNI-T UTG962E Signal Generator as our function generator.

Silly Job Title: Volt Vanguard. I am the Volt Vanguard!

In this video we do the 10th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Highs and Lows of Oscillation.

The spreadsheet with our measurements is here: Maxitronix-30in1-10.ods.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to measure the period of our circuit’s oscillations.

We use the UNI-T UTi260B Thermal Imager to check the thermal properties of our circuit. There was nothing exciting to see.

We use the Carpenter Mechanical Pencil to take notes.

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