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.

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

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 Figure 1N.26: VOM reading departs from ideal; we can infer Rin-VOM.

We use the Riden RD6006 Bench Power Supply to provide power for our test circuits.

We use the Pro’sKit MT-2207-C Analog Multimeter to measure voltage with an analog meter.

We use the Sharp EL-546L Scientific Calculator to calculate some figures.

We use the Multicomp Pro MP701033 Resistor Decade Box to provide various resistances for our circuits.

We use the WilliamKlein Music Stand to hold the book so we can clear some space on the bench.

We use the Carpenter Mechanical Pencil to make our notes.

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