DIY Display Dimmer: Physical Brightness Control for Monitors
My USB-C port replicator does not pass on brightness commands to my external monitors. The idea of a hardware solution was floating around in the back of my mind for a while. Until my friend made exactly this. I decided, if he was no longer fiddling with the screen’s built-in menu, neither was I! HDMI…

LED bed light
I have been working on my own custom wakeup-light on and off for several years (part 1, part 2, part 3). After getting Philips Hue lights, however, I have not gotten around to setting it up in my new apartment. So recently, when the need came along, I figured the quarter round rod I used…

Wake-up Light Part 2: Scheduling
Last time, we had managed to get a command for controlling the lights up and running on the Raspberry Pi. The obvious choice for scheduling such a command in Linux is Cron. To automatically turn on the lights using Cron, we need to edit the root-user’s crontab: $ sudo crontab -e This will launch a…

Wake-up Light Part 1: Flipping switches
I’ve had the idea to build my own wake-up light for quite some time. This winter i finally got around to it. This is the first part of my write-up of the project. In simple terms, the point of a wake-up light is to gently wake you up by slowly turning up the light before…
