Hello list! I am interested in building my own wearable. I have been thinking in three different options: * The Lizzy approach: PC/104 + Linux Pros + I believe it is easy to build + Linux is powerful and flexible. + ISA architecture is simple. A lot of peripherals in the market Cons - Size?, Power? * The custom approach: a microcontroller (may be Hitachi SH) + RTOS. Design and build my own board choosing specific components. Pros: + Smallest + Less power required Cons: - Harder to get the initial prototype. - Incompatible. All the software must be ported - Harder to program and to debug software. Since the target platform and the host are really different you have to debug the software over the target (the wearable) * The commercial approach: using Netwinder or a Windows CE machine or whatever. Pros: + Plug & Play Cons: - It can be difficult to customize to my own project. Is this list reasonable? Are there other approaches? Any hint?
