Why do we believe light is a particle?
One of my aspirations is to understand all the mathematics in this video. I’m not even close yet!
The History of Aluminum
This is what it says on the tin. The reason we had a Bronze Age and an Iron Age but no Aluminium Age was because isolating aluminium is pretty difficult in comparison.

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:
And the charts we make are these:
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.
Thanks very much for watching! And please remember to hit like and subscribe! :)
p.s. today I added Riden, EEVblog, Kaisi, and Multimeter, to my spell check.

Alessandro Volta
Today I read about Alessandro Volta who is the person the “volt” was named after. Volta achieved a number of things but the most famous of them is the Voltaic pile, the first battery.

Silly Job Title: Earth Grounder. I am the Earth Grounder!
In this video we do the 9th project from the Maxitronix 30in1 Electronics Project Lab Kit: The “Secret Code” Key.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to examine the buzzer tone signal.
We use the UNI-T UTi260B Thermal Imager to check thermals (there are none to speak of).
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
