Silly Job Title: Electronics Guy. I am the Electronics Guy!

In this video we continue working our way through Learning the Art of Electronics and begin working through 1W Worked Examples: DC circuits. Particularly we design and implement the 1A ammeter. Next week we will do the voltmeter.

I measure the internal resistances of my various analog meters, which comes out like this:

Meter Resistance (Ω)
100 µA 2,271
1 mA 239
10 mA 27
100 mA 7
1 A 2
5 V 4,916
10 V 9,150
15 V 13,010

We use the METCAL PS-900 Soldering Station to solder our 222 mΩ resistor.

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

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

We use the Riden RD6006 Bench Power Supply to provide test voltages and currents.

We use the EEVblog BM2257 Digital Multimeter to measure various things, particularly resistance.

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

We use the Carpenter Mechanical Pencil to make notes.

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.

Silly Job Title: Electronics Guru. I am the Electronics Guru!

In this video we continue to work our way through Learning the Art of Electronics. In this video we return to 1L Lab: DC Circuits and revisit lab 1L.4.3 in which we made a 10 mA ammeter. This time around we do a better job of it, build two ammeters from different movements, and compare our results with an actual known-good ammeter.

As promised here are the notes:

We use the Tenma 72-10505 Bench Power Supply to provide 5 V for testing.

We use the EEVblog BM2257 Digital Multimeter to measure our resistor and as our reference ammeter.

We use the Sharp EL-546L Scientific Calculator to calculate our shunt resistance.

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

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

Silly Job Title: Terminal Tactician. I am the Terminal Tactician!

In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and test a 1N914 diode.

The circuit we build is this:

LAoE-Fig-1L.8 Diode VI measuring circuit.

And the charts we make are these:

LAoE-Fig-1L.9-linear Diode I versus V: linear plot.

LAoE-Fig-1L.9-lin-log Diode I versus V: lin-log plot.

This demonstrates that as we increase the voltage into our diode the current increases exponentially.

We reverse the polarity of the diode to see what happens and we observe that only a very small leakage current of 0.4 µA flows.

We use the Riden RD6006 Bench Power Supply to supply 5V for our test circuit.

We use the EEVblog BM2257 Digital Multimeter to measure voltage.

We use the Fluke 17B+ Digital Multimeter to measure current.

We use the Carpenter Mechanical Pencil to make notes.

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

In this video we wish you a Merry Christmas and a Happy New Year!

To begin with I explain the cosplay costume I wear on the show. It’s me dressed up as Egon Stetmann the Chief Scientist from StarCraft II.

We take stock of the aspirational video release cadence which at the moment is one video per day:

We have a look at the video cameras we currently have deployed in the studio. We have OBS Studio running on four different computers with camera inputs like this:
