I am a huge fan of Adafruit Industries, which was founded right here in NYC by MIT engineer, Limor ‘Ladyada’ Fried and is a supplier of great DIY electronics projects and an excellent source of information. Adafruit hand-picks quality electronic components, designs their own boards and kits and has an amazing tutorial section. I am no electronics wiz and have managed to put together some pretty cool stuff with their guidance. I love this place.
One of Adafruit’s first kits was the MintyBoost USB charger which you solder together yourself, runs off of two AA batteries and fits in an Altoids mint tin. Throw one in your bag and they are super handy when you need an emergency phone charge. It’s worth the looks you get when plugging your phone into an Altoids tin. I’ve built five of these and from those builds thought of two improvements I wanted to make. The first problem was if the batteries were left in for an extended period of time they would eventually discharge to the point that they would leak and I killed two MintyBoosts this way. The second thing I wanted was enough room in the case to fit a small charge cable, so I decided to design and 3D print my own enclosure.
Today I’m going to show you how I approached this project and printed this custom MintyBoost charge pack….
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! We also offer the MakerBot Digitizer in our store. 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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
