Silly Job Title: Digital Dancer. I am the Digital Dancer!

In this video we unbox the Sharp EL-506TS scientific calculator. In this video I also mention about my Casio fx-991CW and my Sharp EL-546L.

The constants used in the calculator are taken from CODATA Recommended Values of the Fundamental Physical Constants: 2018 which is an impressive scholarly work.

I am sorry for the poor focus and zooming in this video. I have ordered a new camera which should help me to minimize issues like this in future videos.

Silly Job Title: Watt Wizard. I am the Watt Wizard!

In this video we continue working our way through Learning the Art of Electronics and continue 2N RC Circuits.

In this video we try to make a simple current source using only a transistor and a few resistors, for learning purposes. We don’t quite get the circuit running in the end, we will take another look at it soon.

In the back part of the video I take some time out to make some cables which I will use when we continue with this current source project in the near future.

The signal generator come current source which I mention in the video is this one: FNIRSI SG-002 Signal Generator.

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

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

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

We use the Tenma 72-10505 Bench Power Supply to provide power.

We use the Riden RD6006 Bench Power Supply to provide power.

We use the EEVblog BM2257 Digital Multimeter to measure voltage, current, and resistance.

We use the EEVblog BM036 Digital Multimeter to measure voltage.

We use the Fluke 17B+ Digital Multimeter to measure voltage, current, and resistance.

We use the UNI-T UT116A Digital Tweezers to measure resistance.

We use the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer to check the pin out of our 2N2222 NPN transistors.

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 and cut heat shrink.

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