HOW TO Make Your Own $6 Microphone Pop-Filter
This article will show you how to make your own microphone pop-filter. A pop-filter is a small screen that goes between a microphone and your mouth to prevent sharp popping sounds (known as plosives) like “P” and “B” words from overloading the mic level and distorting. Commercially available pop-filters are expensive and can often cost 20 dollars or more. The pop-filter you can build here will cost less than $6 dollars. Link.

There are other I/O boxes that use USB, but theirs has an unusual number of ins and outs, saving you basic stamp programming. And it’s also comparatively cheap. They also make bunches of custom controllers, keyboards, everything…
