Is it possible to use RF signal wires to let a model car center itself on it using phase differences?
I'm looking for a way to let a model car (1/24 to 1/18) know how centered it is on a road. I thought about using a buried wire in the middle of each lane of the road. Would it be possible to detect ...

Estimating max total supply current of all CAN transceivers on the bus
I'm designing the devices that should communicate via a long CAN bus (500+ meters). The power (24V) to the devices is delivered via the same bus cable (UTP5e), by the rest 3 pairs.
The limiting factor ...

Must RS-232 devices use the same logic level?
I want to interface a microcontroller with the RS-232 COM port of my PC.
My PC uses a 75232G IC, which uses +/-12V logic levels as per some multimeter tests.
Currently I'm planning to use the ...
