    You can/could also find Coffee HOWTO in your distro’s HOWTO package. (I found a reference back to v0.5 of the document in 1998.)

    Has simple schematics to get you started for the hardware, using the parallel port to toggle relays.

    It’s a very neat little document, and inspired me to write a simple kernel module so I could echo 1 | sudo tee /sys/whatever/coffee0 to turn pin 0 high on the parallel port. (This is silly, and it’s much easier to just do things in user space!)

    Not a historian, but folks on The Internet have characterized the Soviet program as a series of milestones, with the US program a series of stepping stones in support of a single goal.

    This makes sense with the cartoon, where the Soviets were first in basically everything except walking on the moon.

    Not sure how much merit it has, but it’s kinda interesting.




  • Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

    My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

    It’s a fun exercise, not sure I implemented it in a smart way, but it works :)






  • Especially after adding in all the power draw of the automation requires…

    What exactly is the incremental power draw for automation? My network gear and server (a little nuc) are sunk power costs as I self host other services.

    Idling, my home uses around 100W with the fridge off. One 10W light is an additional 10% of my power budget, and I have a lot more than one light in my house. I also pay about $0.40/kWh.


  • I can be a bit neurotic about turning off lights when I leave a room, so Home Assistant was a nice way to free up brain space for me. A few motion sensors here and there + some simple automations, and the lights mostly handle themselves. Zigbee sensors and Zigbee or Matter-over-WiFi bulbs, so everything is local. A free VPS+WireGuard setup means I can access them remotely should I need to, with TailScale as a backup.

    Cloud failures mean I can’t access remotely, but local control is unaffected—if my smart devices stop working it’s almost certainly my fault :)
