Does anyone know of a back light that turns off after 5 minutes of no movement? I'm tired of backlight being out of juice just because I forgot to turn it off ... I'm tempted to make a circuit and maybe even the sensor myself but I don't have the time for it and it probably already exists.
If you use a bike computer: the Garmin Varia tail lights auto shutoff shortly after disconnecting from the computer, and the computers themselves have auto shutoff after a period of inactivity.
A bicycle tail light that wirelessly connects to a central computer to turn itself off? I really hate the timeline we live in. Back in my time a bicycle tail light was connector to a dynamo and a capacitor. It would automatically shut off after a minute or two. No Bluetooth required.
Turns out, the simple way had some shortcomings that were only solvable by making things more complicated. I don't see an alternate timeline where that isn't true, unless we stick to an agrarian society. Banks were a mistake.
What shortcomings did it have? Like never having to charge anything? Not needing an app? Not needing wireless communications? Not needing to pair? Sound like terrible shortcomings.
