This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

Power diagram for vacuum bot ...
another wiring change
Actually this is for the smaller vacuum bot , not.the omnibot 2000 , I really should name these guys...
oh.i see the head of it now,one with the dome top ,omnibot
i have 2 of them at home,also hope you are adding fuses to it
I need a dome , do you have a good one?
no sorry ,mine is scratch alot,need to rework it,bought a special scratch removal kit and special sandpaper to see if i can remove the scratches,other one restoring it there is a place that has domes for sale to fit it perfect $40,same size only the lip needs a little work
Josh,
Two questions probably simple answers :-
Why the dc - dc converter can't the EZ-B run on 12volts ? For the Cam why don't you run the power from the EZ-B ?
I think I know the answers to these questions but I'm still learning so thought I'd ask.
Regards
algeraist you need 7.5 volts any higher the regulator gets very hot,you should be able to run it from EZB only noise might be a problem,i takes very little current to drive it
dc-dc converters are very good to get rid of noise,but low drop out regulators are better,but need a filter,i design dc-dc converters at work
aslo whats bad about its very important you watch the discharge level of the battery you are using ,if you go too low ow of voltage using a dc-dc converter,when you try to charge it ,it will go bad so very important to have a voltage monitor ,witch is mostlt a zener diode,and a voltage devider hook up to analog port,or a simple voltage comparator to digital port can buy them but will cost you 3 to 4 times mores ,parts are under $2
