The nice thing about the current display is it is cheap, universal and will never be obsolete. You will always be able to buy video monitors and the small lcd ones from China are dirt cheap. The SV2000 serial to video chip will be replaced in V3 with a Tellymate which is cheaper, open source code and gives better resolution. The problem with using surplus hardware like old palms and windows mobile pdas is you keep chasing a moving target as old equipment becomes unavailable. Not a problem for a one off project, but if someone is trying to duplicate it, there could be a lot of re-engineering if the particular palm, ipaq, pda is no longer available. The existing hardware could be made to work as a "headless" BMS with a relatively small amount of work on the code. The hard stuff has already been done.
My personal view is that in my own car I don't want a car-puter, the existing display is fine. It would be nice to have data logging to say a SD card. I know there are some Arduino projects that do this. I haven't investigated it for PicBasic, might have a look and see if someone has done that already. I would be happy to have a data log to a SD card and then analyze it later. Even better would be to make the data "loop", a bit like a black box. You just leave the card in unless you notice a problem, then you can take it out and analyze it at home.
