It's a fun project!! Don has a video on YouTube of how to do it. I also enjoyed the titanium anodizing thread in the McGizmo sub forum. The clip is a diamond etched clip that I purchased from Don. I anodized it yellow and then sanded the yellow off the high points and anodized it blue - it almost looks like lightning to me. I was only using 9volt batteries and a solution of TSP and tap water but I couldn't resist dunking the Makai. My blue was three 9V in series so approximately 27V. Now I want a power supply.
