This is a charger I have created for my small bluetooth controlled track loader.
This makes it possible to charge the track loader with a standard phone charger that uses micro usb plug.
It also enables you to check the cell voltage of the battery inside the track loader. When no usb cable is connected it displays the actual cell voltage. When a usb cable is connected it display charging voltage.
Through the 2 small holes in the bottom you can check if its still charging or its done.
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!
