So I finally got around to testing out my EZ-B. I have all my stuff plugged in, and as soon as I power it on, several of the items connected to it start running - without any controls associated. It connects up just fine but a soon as I attempt any control it disconnects. My thoughts are that because a couple of things are already running, as soon as I try to do anything else it is browning out. I am using the battery pack that came with it.
Thought: Should I disconnect all peripherals then power it up and slowly add items and test their control that way? Also, what would be an optimal battery pack to work with?
Sweet, I love all these Ideas! And thanks for the diagram!!!!!
So Upgrading my battery made all the difference. I am using the 6V 4.5ah battery for the omnibot. I tied the HD servos into the 6v power and everything is working wonderfully - ie. no dropped connections. I have noticed the external power supplied servos work better than the mini servos plugged solely onto the board. Those little servos flutter a lot and don't give full motion.
@dj I just tested a standard single pole double throw 6v and a 12v relay rated at 30 amps and they are drawing drawing 100ma that's 1/10th of an amp you must have used a household AC relay with 12v or somthing
Ok second test , I tried a 6-12v radioshack reed relay rated 10th amp and my meter shows 23ma. Less than 1/20th amp to power so its plenty efficient to use to connect accessories power on without passing through ezb at all. This way if you hardwire a camera , have ezb and servos direct to a power source you can use one switch and some basic reed relays and everything powers on or off with one switch.
