Make your own BMO with 3D Printing and DIY electronics. This adorable robot features a mini 8×8 LED matrix and GEMMA, adafruit’s tiny arduino-compatible micro-controller.
3D Print the parts, solder the components and assembly this cute video game robot to have an awesome adventure time!
Grab the files on thingiverse and 3d print the parts in your favorite color.
The Mini 8×8 LED matrix powers 64 LEDs to display bright and super cute animations. Here’s what the complete circuit looks like. The push button should also have enough slack for it to move around in the enclosure. Gemma acts as BMO’s brains, while the LED matrix+backpack is his face. We can assume the battery is his heart
You can print BMO’s buttons in different colored ABS or paint each piece.

Guest Curator Emmett Lalish has this to say about this 3DxMechanicals project: “I love this because it’s so simple, yet so effective and shows off how to design with flexibility in mind. This is such a perfect application of 3D printing. And don’t be afraid to use non-printed parts; this uses printing only where it actually helps the design.”
Tri_Max_Gripper ( Conforming Robotic gripper ) by Chiprobot:
This is a Robotic gripper that adjusts its grip to conform to the shape and form of the object picked up.
Its printed with normal PLA (ie does not have to be flexi pla). More details of build can be found on my robot page here.
The drive mechanism is a simple standard servo modified with a linear actuator made from a “Glue stick” and linear feedback potentiometer. Details on servo conversion can be found here.
This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Starter Kit,Extended Kit, Deluxe Kit, and Synth Kit.
A zoetrope is a device that produces the illusion of motion by rapidly spinning a series of static images. It is a classic invention with ancient roots and has gone through many iterations over the years. We thought we would put our own “spin” on the zoetrope using littleBits and 3d printed parts.
For this project, our circuit was relatively simple. It has a DC motor and three bright LEDs controlled by a pulse. We also used a button in combination with a latch in order to be able to turn it off and on.
The DC motor sits in a custom 3d-printed vertical mount so that it can stand up on its side. We made this vertical mount by modifying a file from our friend rbrodie. A large chipboard disc with 30 3d-printed figures sits on top of the DC motor via another 3d-printed connector. To make our animated figures we used 30 frames from a 3d animation file we found on Blender’s tutorial page. The whole contraption sits inside a dark box that has two small holes for viewing. The figures come to life with the DC motor and the addition of three fast pulsing bright LEDS.
If you don’t have a 3d-printer, but would still like to be able to use these parts, you can 3d-print our files via Shapeways. Shapeways is a 3d-printing marketplace and community. If you don’t want to go the 3d-printing route, try creating figures using Lego or clay.
You can also find all the 3d files for this project on Thingiverse.
