Silly Job Title: Grounding Genius. I am the Grounding Genius!

In this video we continue to work through our Maxitronix 30in1, today doing project #8: The Slow Motion Sunrise-Sunset Light. In this project we see how an electrolytic capacitor can control a Darlington pair.

We use the UNI-T UTi260B Thermal Imager to examine the thermal properties of the circuit (there’s not much to see).

We use the OWON XDM1041 Bench Multimeter for voltage and current measurements.

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

Silly Job Title: Science Officer. I am the Science Officer!

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:

Silly Job Title: Bolt Boy. I am the Bolt Boy!

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 make an 10 V voltmeter with our meter movement.

We use the Riden RD6006 Bench Power Supply to provide test voltage and current.

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

We use the Sharp EL-546L Scientific Calculator to do our calculations.

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

We use the WilliamKlein Music Stand to hold our textbook.

We use the Carpenter Mechanical Pencil to make our notes.

We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.

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

Silly Job Title: Phase Pharaoh. I am the Phase Pharaoh!

In this video we take a look at the Archer Semiconductor Reference and Application Handbook, 1978 edition. This old book from Radio Shack outlines their semiconductor portfolio as it was in 1978.

This book is available online over here: https://archive.org/details/archer-semi-1978-ed

In the video I accidentally skipped over a few pages: 14 and 15 and 40 and 41 and 44 and 45 and 50 and 51.

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

In this video we continue to work through our Maxitronix 30in1, today doing project #7: The Sunrise-Sunset Light. In this project we see how an electrolytic capacitor can control and NPN transistor. By varying the resistor and capacitor we can change the timings of the circuit.

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

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