Hi, I've just purchased my CyberMatser, and I already have some 20 questions.
Here are some battery related:
How many mA does the Tower Unit consume?
How many mA does the Mobile Unit consume with both internal motors and the external active?
Would a 7809 (and a couple of capacitors) stabilize the voltage safe enough?
The reason I ask is I plan to make a wooden dummy 9v battery for the Tower with two wood screws serving as electrods,
wired to a 9v DC converter.
Maybe also two 1.5v for the Mobile Unit, but that would not be really that practital as it is just mobile...
