new project: solar rover based on Picaxe 18X

the idea is to use a picaxe 18X as a brain for a little solar rover.

i have discovered that a picaxe can function as a solar angine because it works down to 2.5 volt

so im planning to use a solarbotic 33x37 policristalline cell wich provide 6.3V - 30ma

picaxe remain in nap mode untill caps reach a voltage near to 3.5 v then activate motors to accomplish an action loop....

and so on....

i use a 74ac240 as motor drivers and geared pager motors ...

 

by the test i have done till now it seems all can work properly....
