Some AI datasets have directories where each directory represents a class. A particular directory can contain a large number of files. Because of time and memory constrains you may want to train your model using a smaller number of files.

We detail how to move the…

When using the latest version of Raspbian Stretch, a variable named VIRTUALENVWRAPPER_PYTHON must be set to the path of the python version that you want to use when creating virtual environments. You can create python virtual environments that use python2.7, python3.5, python3.6 or python3.7. We will use python3.5.

It takes just a few minutes to design a nameplate using the Codeblocks application in Tinkercad. The export button in Codeblocks quickly creates a .stl for the nameplate to be 3D printed.

Here are the codeblocks for a nameplate:

If you are not familiar with Tinkercad’s Codeblocks see An Introduction to Tinkercad Codeblocks. Objects in Codeblocks may be considered to be parts. To illustrate this, consider designing a wrench. …


One of the benefits of using tinkercad codeblocks is that you can easily create patterns that can be used to decorate your 3D prints. A good example of this is the Tea Light Holder:

Tea Light Holder (Lighted with a LED)

The basic pattern for this is simple and shown below as four holes.
