Today I attempted (yet again) to make a hotwire with the 1.27 micron wire instead of our usual 3 micron stuff. When Stephanie etched the metal, we got a truly bizarre curlicue in the 1.27 micron wire. Miraculously, it didn’t break; but it was totally unsuitable for use in the wind tunnel. This particular image is one I took by holding my camera to one of the eyepieces of our microscope. It’s crude, but effective.
