The Raspberry Pi makes a great USB webcam for $100

There are many Raspberry Pi projects where I spend a few hours (or dozens of hours) building something with a Pi, and realize at the end that not only could I have purchased an off-the-shelf product to do the same thing for half the component cost, but it would work better too.

But this is not one of those projects:

Pi Webcam on Tripod - Pi Zero W and HQ Camera

The Raspberry Pi and its HQ camera make a surprisingly potent webcam, and if you want to cover the basics, and rival the image quality of all but the highest-end dedicated webcams, you can do it for under $100.

Above is a single frame from a recording I did with the HQ Camera on my Raspberry Pi Zero W connected as a standard USB webcam using the Camera app on Windows 10 on my Dell laptop.

Hum or Buzz with a Logitech USB Headset

Logitech USB HeadsetProblem: I've heard from a lot of people about hum or background 'buzz' in recordings and Skype conversations when using a USB headset (like the one I have, the Logitech USB Headset H350). Almost every time I hear someone having this trouble, they're having the problem while using the headset with a laptop.

Solution: about 99% of the time, the problem is fixed by simply plugging the laptop into a grounded (3-prong) outlet.
