This is a follow up to last week’s video – If you connect inverters inputs to their own outputs – will they get hot? I use a FLIR thermal camera to check the temperatures as well as measure the current for comparison. Finally I take a look at the data sheets to help explain what might be going on.

If you take a NOT gate and connect it’s output to it’s input, what will happen? I explore this very question in today’s video, where I use an an Arduino as a basic oscilloscope, and then a higher end oscilloscope to verify my findings.

In this video I demonstrate an odd effect – I’m able to squeeze a wire, and cause the voltage on it to decrease. What could cause this to happen? To understand this, we’re going to have to understand both capacitors, and the concept of floating voltages.

I was wondering if AC Power could be used as a timing reference in an embedded system. I realized that there were some things that likely used AC Power for timing – the example that came to my head was an outlet timer!

In this video I delve into the zero ohm resistor. Why would a resistor with no resistance be useful? Well – there are 3 reasons.

For my EE2180 – I’m creating a stepper motor controlled Etch-A-Sketch for a laboratory experiment. Here are some my notes of it’s development / construction.

In this video I demonstrate two Arduino Nanos communicating with one another via an I2C bus. I use a digital storage oscilloscope to look at the data and clock signals, and then dissect the information present in the signal.

Experimenting for the sake of experimenting is a great thing that I’ve lost touch with. So in this video I took a look at a question that I wasn’t quite sure about: Can I use one part of a bipolar junction transistor as a diode?

In this video I get curious about how the plastic fortune telling fish is able to divine the future, both by testing student’s theories as well as information dredged up from a quick literature review.

In this quick pilot video I use an Arduino paired with an IR sensor to get curious and see if an old remote is still generating a signal. And if it is generating a signal, what does it look like?
