Re: (ET) New Cards

[steves <ssawtelle erols com>]

I make my living embedding micros in stuff. I'm not sure what could be 
gained by putting more control in the ET (other than a full up PWM 
controller - and I know that's not universally  agreed on). The existing 
system is somewhat complicated, but works very well for something that 
is mostly mechanical. Replacing the existing components with more 
robust, modern semiconductors would fix a lot of problems we see. Bad 
connections are another problem area could be addressed.

I did make an 'ET meter' for my E20. It has a micro and LCD. Shows 
voltage, current, stores data, etc. But, you know, I'm not sure if I 
gained much over the existing meter setup. Chris's idea of monitoring 
individual batteries is probably the best add-on feature I've heard 
about and it's pretty simple as I recall.

All that said, I love experimenting, so if you have an idea and need 
help persuing it, I'd be glad to help.
