My COVID project was DCSkyCam[1], which is on a Pi4 with the HQ camera to do sunrises/sunsets, and uses TFLite and other packages for object detection and identification of helicopters that fly by.
I also have a Pi 3B running pihole[2] and running custom scrape jobs to alert me of certain website updates, which I’d like to transition to using selenium but the 3B is too slow for chromedriver - might upgrade to a Pi 5 if I can.<p>[1] <a href="https://dcskycam.net" rel="nofollow">https://dcskycam.net</a>

I have some olds Macs lying around and can't install Tailscale on older OSes. I got a Pi02W working as Tailscale subnet[0], so I can access all my devices on LAN remotely.<p>[0] <a href="https://tailscale.com/kb/1019/subnets?q=Subnet%20routers" rel="nofollow">https://tailscale.com/kb/1019/subnets?q=Subnet%20routers</a>
I'm using a pi as a firewall between my house and a 30 meter ethernet cable to my shed.<p>I wanted ethernet to my shed but found that physical security of ethernet was a little pricey. I'm using an old pi, a cheap ethernet dongle I got in lild in a sale and ipfire to create an isolated network in the shed.
I made a smart pinewood derby track. Used a reed switch to start a timer on release of the cars and ultrasonic distance sensor to stop the timer when the first car crossed the finish line. Displayed the data on a TV mounted above the finish line. That was a fun project.
