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.

How Heavy Is an Electron?
Spoiler alert! The charge on an electron is e = 1.60217663 x 10-19 C and the mass of an electron is m = 9.1093837 x 10-31 kg. Check out the video for tips on measuring these values yourself!
