Still no sound. Getting stumped.<\/li>\n<\/ul>\n<p>I also acquired a number of useful tools this weekend &#8211; a mitre box\/backsaw combo, a center punch, a clamp, nibbler tool (which should allow me to cut rectangles!), some electronics-quality tweezers, and a set of helping hands.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What did I accomplish building-stuff-wise in February?
