Just me showing how I use an oscilloscope to probe around a signal. This was inspired by a conversation I had with some beginners who had an oscilloscope, but didn't actually know how to use it. I go into a lot of details on how I actually use the scope.

I saw Neil Degrasse Tyson talking about color on the NIRCam pictures. I thought there might be more to it, so I decided to expand on that.

Mixing milk, food color, and dish soap is pretty cool

Just a quick example of how to use dprintf, which allows for the familiar "printf" style debugging using gdb.

I tell a story about this guy I know, and take apart a fancy pen refill.

I wanted a simple project, so I made a light that stays on for about an hour

I'm messing around with an FPGA, and I wanted to show you a basic FPGA development tool that was not included in the starter workshops.

I'm using an Icebreaker FPGA, and the open toolchain (Yosys/NextPNR).
