Freewheel diode / capacitor with this board? [closed]
With DC motors, it is common to put a freewheel diode and/or a capacitor in order to protect the equipment as the motor can induce current into the system. I plan to use this board to control a 24V ...
Can GPS modules work inside plastic enclosures?
I'm going to be embarking on an autonomous robot project and I was going to be using GPS to navigate to waypoints (I'm aware of the margin of error when it comes to localization with GPD but I live in ...
Protecting electronics against voltage/current extremes and bad polarity
I have built a robot from a wheelchair that has worked very well thus far. It is now time for me to take the next step. I need to implement a permanent power circuit with proper protection. The ...
Why are capacitors added to motors (in parallel); what is their purpose?
I've seen many motors having capacitors attached in parallel in bots. Apparently, this is for the "safety" of the motor. As I understand it, all these will do is smoothen any fluctuations--and I doubt ...
Preventing leaks in motor shafts for underwater bots
Whenever building an aquatic bot, we always have to take care to prevent leakages, for obvious reasons. Now, holes for wires can be made watertight easily--but what about motors? We can easily seal ...
How can I best protect sensitive components against damage through vibration?
It's common for components on some types of robots to experience large environmental stresses, one key one being vibration. Is this something I need to worry about with typical electronics and other ...
