They're basically variations on the same base design I put together when specing out the MIT project's requirements. The best thing to do is to look over both sets of instructions for the "tricks of the trade" and then mix and match for what you want. Personally, I think the best route is to make a Lizzy, but using an Ampro VGA card (low power) and an M1 display (modify mount for your head) instead of the Private Eye (unless you can get one - still my most used display). Combine this with Steve's power bridge instructions and other tricks and you have a nice machine. This way you get the benefits of both sets of instructions. The Lizzy is good because of its detailed parts list, specific steps, and long testing by many people - the web instructions are still the base of most of the wearables made at MIT. Steve's instructions cover some of the power and VGA/NTSC issues I ignored in the published version. In actuality, we spent a long time trying to spec out decent VGA boards. Advantech SVGA has the picture quality of a true 24-bit card but draws a lot of power; Ampro SVGA-II has OK quality for much lower power (ampro SVGII with 1M VRAM cirrus logic chip .5W); Jump is equivalent to Ampro but with slightly higher power (1W).
