Silly Job Title: Systems Architect. I am the Systems Architect!

In this video we keep on working through Learning the Art of Electronics chapter 1N DC Circuits. Today’s circuits are from Figure 1N.25: Set of similar voltage dividers: same Vthev, differing Rthev and Fig-1N.29: DVM reading departs from ideal; we can infer Rin-DVM.

We use the Tenma 72-10505 Bench Power Supply for a 20V power supply.

We use the EEVblog BM2257 Digital Multimeter as our DVM for measuring voltage.

We use the Sharp EL-546L Scientific Calculator to crunch some numbers.

We use the Multicomp Pro MP701033 Resistor Decade Box to provide the resistances used in our circuits.

We use the WilliamKlein Music Stand to hold our textbook.

We use the Carpenter Mechanical Pencil to make our notes.

Silly Job Title: Circuit Sorcerer. I am the Circuit Sorcerer!

In this video we make a cable for connecting the TENMA power supply in the booth to a power outlet on the bench. We use 4mm banana plugs for the TENMA connection and output to a female DC barrel jack on the bench. The wire is scrap speaker wire I had hanging on my pegboard, it was plenty long enough. In fact I had to coil up the wire and zip tie it under the bench. Hopefully the coil doesn’t induce any currents!

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

We use the Horusdy Soldering Station with Hot Air Gun to shrink our heat shrink.

We use the MUIN Solder Fume Extractor for fume extraction.

We use the Tenma 72-10505 Bench Power Supply to deliver power for testing.

We use the EEVblog BM2257 Digital Multimeter to test the cable with a voltage test.

We use the Brother P-Touch D210 Label Maker to label our new power cable.

We use the Bysameyee Head-Mounted Magnifier for illumination while under the bench installing the cable.

We use the Scotch Titanium Scissors for cutting the heat shrink.

We use the Plato Model 170 Wire Cutter for wire cutting.

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