Jenny Holzer printer (video)

It’s really easy to change the output of the Internet of Things Printer— the Twitter query is just one line of code you modify in the Arduino sketch. In this video I show you how to reprogram the IoTP to print Jenny Holzer aphorisms directly on my desk (although yes, I realize the twitter account isn’t run by Holzer herself).

The Internet of Things Printer is open source: you can read the tutorial, download the code and enclosure laser files, and please share your own versions with us in the Adafruit Flickr pool!


NEW PRODUCT – Adafruit IoT Printer Project Pack “Internet of Things” printer. Build an “Internet of Things” connected mini printer that will do your bidding! This is a fun weekend project that comes with a beautiful laser cut case. Once assembled, the little printer connects to Ethernet to get Internet data for printing onto 2 1/4″ wide receipt paper. The example sketch we’ve written will connect to Twitter’s search API and retrieve and print tweets according to your requests: you can have it print out tweets from a person, a hashtag, mentioning a word, etc! Once you’ve gotten that working, you can of course easily adapt our sketch to customize the printer.

The project is not very difficult but does require some light soldering, so you’ll want to have a little experience with a soldering iron. You’ll also need a small flathead screwdriver to assemble the box. It’s also best if you’ve had a little Arduino experience so you can feel comfortable downloading the IDE and uploading our example sketch.



This pack does not contain an Arduino+Arduino Ethernet Shield, Arduino Ethernet or Ethernet cable To complete the project you will need to add either an Arduino + Ethernet Shield or an Arduino UNO Ethernet. If you’re using an Arduino UNO Ethernet you will also need an FTDI friend or FTDI cable to upload the sketch. A plain straight-thru Ethernet cable is also required (any length)

Before purchasing, please check out the full tutorial with images, code, etc!

    What I like about this printer is that it’s way more interactive than all the other thermal printers that have recently been released. I think you’ll probably be able to find more uses for a gadget that you’ve assembled yourself…nothing quite like the pride of having built your own gizmo!
