I’ve been experimenting with a new method of doing printing timelapses. I’m pretty happy with the look so far.

I have an arduino connected to a reed switch sensor which triggers every time the print head moves out of the way (which happens because I’m also printing a sacrificial tower on the other side of the print bed). The arduino then sends a trigger signal to my Canon 20D over the analog remote port (litterally just connecting a pin to ground through a transistor). It then waits 10 seconds before starting to check for the signal again so that I don’t get double shots. Here is my whole (super sketch atm) setup.

The wiring diagram is here. Check out this site for more info on the camera connection.


Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
