Create Miniature Interactive Art with a Raspberry Pi and a Touch Screen

Share

Processing is a programming language that allows people to make visual art (amongst other things) using programming and recently it released a version that works on the Raspberry Pi. Adafruit put together a guide for getting it on the Pi and working with their touch screen.

This project works on a few levels. First off, it serves as a nice introduction to Processing, which a fantastic entry point for people who are new to programming. Second, it shows you how to create a cool little interactive display that looks a lot like a miniature art exhibit. You can even hook the Pi up to a breadboard to control various lights and colors. Head over to Adafruit for the full guide.

Cool a Raspberry Pi with an Old Computer Fan

Share

The Raspberry Pi usually runs cool enough that you don’t need a fan, but if you’re overclocking it or running something particularly intense, it’s helpful. Don’t go hunting for some specialized fan though, as YouTuber NetHacker points out, any old computer fan will work.

NetHacker pulled out a fan from a junk computer, plugged it into the Pi’s GPIO, and got it working instantly. If you have an old computer sitting around, it probably has a fan that’ll do the same job just fine. If not, you can usually snag one for a couple of bucks.
