Replying to say dd is probably the better method for archival, but this works for me in most cases.

This should work for -most- DVDs, unless they’re using some unique copy protection.

The following packages are needed: dvdbackup, libdvdcss, cdrtools

To get info on an inserted DVD (and check it can be read): dvdbackup -i /dev/sr0 -I

To rip the DVD to a directory (-M will mirror the disc): dvdbackup -i /dev/sr0 -o /path/to/store/dvd/ -M

And then to write the directory contents to an iso image: mkisofs -dvd-video -udf -o /path/to/save/movie.iso /path/of/ripped/dvd

From there you can archive the iso, mount it for playback, etc. My next step was a combination of MakeMKV and Handbrake to encode the main movie (H.265 MKV 480p30) for storage on a media server.

I’ll second this as someone who used to administer an AMI headend. This is essentially an industrial wifi access point. This device connects to the utility’s operations network, and provides connectivity to smart meters in the area.

This video is almost 15 years old. Link: https://youtu.be/0yfArN-e2OU

At least the sequel is relatively new but sadly (?) doesn’t include timestamps like the first. Gotta respect the hustle though.

My curiosity got the best of me, here’s the link to Wright: https://www.wrightmfg.com/products/mowers/commercial/stand-on/robotic-zk/

The Mower

• 40HP Vanguard Engine
• Hydro-Gear Smartec Drive-By-Wire 12cc
• 15.5 Gallon Fuel Capacity
• Centimeter-level accurate RTK GPS
• Commercial-grade Inertial Measurement Unit (IMU)
• Depth-sensing object detection cameras
• Rock-solid wireless emergency stop
• Remote control mode
• Live Greenzie support: Call for support while in the field for real-time fixes.

The Software

• Mow the boundary once, and the mower fills in the rest
• Remembers maps and can repeat them when you come back. Just place it in the previous boundary.
• Create no-go zones that will be saved with your map to avoid hitting hard-to-see obstacles like drain covers or small pipes sticking out of the ground.
• Record and repeat: Record yourself mowing the entire property, and the mower will replicate your movement.
• Manage the mower with the controller or a smart device in real-time.
• Advanced fleet support: See how your fleet is performing. Replay entire jobs, not just a dot on the map.
• Run multiple units at once.
• Set the stripe angle (for those stunning cross-hatch patterns)
• Seamless automatic updates

Take a look at the thermometer/hydrometer from SwitchBot (also available on Amazon). $14 each, but available in packs of 2/4 at a discount.

Nearly all SB products seem to have data export from the app. I have three temp sensors (inside/outside/garage), and also use the smart plug mini to monitor and store power consumption data for devices.
