<p>I know, I can already hear you thinking it…</p>
<p>”What is PWM and why is there a disco ball on an Eco web page!?!?”</p>
<p>Well, I’ll be the first to admit that this has nothing whatsoever to do with raising chickens, composting, baking your own bread, or anything else you might typically be thinking of.</p>
<p>However, it has a LOT to do with DIY, a culture of continuous learning, thrift, and ingenuity. </p>
