22 Dec 2009 21:16 Voltage drop question Hi All; Total noob, first post I'm working on a small robotics project. I have an embedded computer (5V) and 2 motors with a controller. It's all powered from a 4.8V NIMH battery. The problem I'm having; As the battery gets somewhat tired and I load the motors for starting or climbing a steep obstacle, the voltage drops a little from 5V to about 4.5 momentarily but it's just enough to restart the computer. What I'm thinking of to solve this problem is adding a capacitor to the power cable of the computer. Would that help the problem? Like I said the drop only happens for a fraction of a second. I know I could use a bigger battery but I have a room issue already as it is. Thanx in advance.
