Ultrasonic Ruler #3DPrinting #3DThursday

3D Printing, LED and sensors equals ray blaster! In this guide, we’re building a Dune inspired movie replica using 3D Printing and electronics. A stylized enclosure makes this distance sensor into a hand held sonar measuring tape. The design features a unique handle and a large barrel that fits this project nicely.

In this circuit, the trinket write’s the distance to a LED display. The EZ rangefinder is a great sensor for reading proximity and measuring distance.

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!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. The link goes to a 404 page :/ I was interested in this to see how some of the code was done…I am considering the trinket (one of the versions) for a project that has similarities.

  2. Updated link to learning guide, please try it again! https://learn.adafruit.com/ultrasonic-ruler
