Project electronic enclosures are the cases around electrical components. It’s more than just to make a homemade device “look pretty,” however. As explained by Becky Stern in “Creating Project Enclosures,” the cover protects a project from outside elements.

It allows users to carry the electronic items they create with them wherever they go.

Now, an enclosure will not necessarily protect against heavy rain or snow. However, it will at least keep units dry when a few drops of rain fall while transporting them from a building to a vehicle. A project enclosure also prevents dirt from entering electrical components. This optimizes the performance of all devices encased in them. The best project enclosures will still allow users to operate their devices from the outside of the case. Recommended enclosures for devices, however, include the ability to remove them for repairs and cleaning (but a well-made enclosure will prevent most dusty entry).

The most fascinating aspect of project enclosures is the materials. Some hobby electrical projects may even stay protected in a used takeout food container, for instance. For more professional-looking projects that are confirmed as up to “selling” code, however, a case made for the electrical device created is recommended. It depends on the intention of the project, as far as what type of case to use.
