Are you talking about the BASIC stamp? I've got that too...however,
it is the BSI. I got this to start learning about microcontrollers.
Very interesting stuff...apparently you can do almost anything with
this. My problem is that I do not know the BASIC language...quite
familiar with C++, but not BASIC. If you know of a site that will
teach BASIC from the bottom up, please let me know!
Otherwise, I have started to design my own circuit for the 3V back-up
power supply. I've started out with relays, capacitors, and
resistors, but I think I will require transistors in place of the
relays. Now, I am more inclined to think it can be done with a BASIC
stamp. It could be easy depending on how well I get to know the
Thanks for the input! And please, once again, if you know how or
where I can learn BASIC for free let me know.
