I'm a newbie as well, although I've nearly advanced to the "put stuff together" bit ; ) Laptop batteries are a reasonable method, but they do vary widely. You may want to look into camcorder batteries. They seem to have standardized on form factors which laptop manufacturers haven't necessarily done yet. Battery life depends a lot on usage and power management. Remember that your HDD is most likely the most power consuming thing in the system. You may want to look into some of the algorithms involving machine learning for spinning it down. The display looks reasonably good, but consider that 640x480 "requires" 307,200 pixels which is approximately 70,000 more pixels than that display has. A display over a single eye is a bit disorienting at first. You lose depth perception and walking down steps is initially a bit of a trial. You get used to it, but it's a good idea to have an easily removable display, just in case. -Phil/CERisE On Wed, May 28, 2003 at 03:52:32AM -0700, Jennifer Pellinen wrote: > I have been interested in wearable computers for a few > years now.
