OBS is really the big enabler in (my) online teaching at the moment. I use an IPad with a drawing app, I draw on a predefined colored canvas and overlay it in OBS with a chromakey filter. If that is available to you, it is even cheaper. But then again, I am looking slightly down while writing..

Just the other day I was following some complicated tutorial for getting blackmagic's atem mini pro hdmi capture/mixer board to work in Wine in Ubuntu 20.04 .. I finally gave up and tried decided to play around with a webcam in obs instead. There to my surprise, OBS was listing the ATEM's capture input out of the box no wine required, with no config as a video source!

I would consider top 10 on HN front page to be "going viral."

That seems like a pretty low bar. When I think viral I don't think, "gets to the top 10 submissions of a niche forum".

I suppose it depends on what you're used to? From my own (and other people's) experiences, you can have a project with a few hundred site visits - get towards the top of HN, and you can have 100k visits over the next few days.

A good enough project on HN tends to get coverage elsewhere, a lot of Tweets etc etc.

“It was under $60 at the hardware store”

So this isn’t actually any cheaper than what I would think of as the standard solution, which is to buy A drawing tablet (which also conveniently doesn’t take up a ton of space in your living area)

Name brand (Wacom) drawing tablet for $60:

Were you using Zoom? I had a lot of trouble using either the OBS virtual camera or sharing the composition window---what was transmitted was either potato quality or the video lagged very far behind. After a LOT of debugging, I'm convinced it was due to Zoom bandwidth throttling, which I was unable to get waived.

Using Zoom with OBS (virtual camera) works fine for me.

In some cases it looked fine for me but for the other persons it looked really ugly. Make sure you use the v"2nd camera mode" in screen sharing options of zoom. Do not do it as your own camera or it will look really bad. On Linux, I have to start zoom after Obs and the virtual camera for all that to work properly.

Huh it looks like she horizontally mirrors the camera so that the writing appears forwards not backwards. At first I thought she might have been writing in reverse, which would be doable on simple graphs but harder with more words. Later shots show her writing on-camera, forwards from her perspective.

In the past century, glass chalkboards and reverse writing were actually used in the military, mainly in air defense. Specially trained writers were putting objects scanned by radars on the board with coordinates and related info, while officers were reading them from the other side.

My late grandfather was a Radarman in WWII and learned to do this.
