Home electronics can open up a new dimension in home automation especially when used with an Arduino or Raspberry Pi. There is however a very real danger when using mains electricity, including risk of electricution and danger of electrical fires if the components are not rated correctly. See this guide on risks when working with …

I needed to control a DC motor from my Raspberry Pi’s GPIO port as part of my time-lapse dolly project. I had to be able to turn the motor on for approximately 150ms which would in turn move the dolly along by 3mm. Parts 12VDC Mini High Torque Motor – Max 50mA at full load …
Typically as a programmer you will work with data on disk, and if you are lucky you will draw pictures on the screen. This is in contrast to physical computing which allows you as a programmer to work with data sensed in from the real world and to control devices that move in the real …
A few times a year I volunteer to an arts organization and serve as their “house sound and light guy.” I usually run sound and do the lights for the traveling acts if they don’t have a tech with them. The auditorium is in a rural Minnesota area, but even so, we try to host …
