here are some ideas to have less problems with you robot
one is try to keep signal wires seperate from power wires.if you cant then twist the power wires to blocks the EDDY currents
another is use SPG (single point ground) witch is all grounds go to a center point or screw
if you looking at why your board sometime resets or other problems,(unstable readings)
this might be the cause of it
been wiring boards for over 25 years,from slot an pinball machines,very precision equipment ,plus robots
working on building a full size full detail design
on wiring you keep all analog and digitals together on one side and power wires on the other side of the robot if not you can twist the red and black power wires together
Ok so I get keeping them separate. I thought that would kind of be a give in.
i started to get parts together little at a time ,plans comming out soon ,hoping by 2013 for SHORT CIRCUIT 3 movie
here is the website for plans
JOHNNY FIVE ROBOT PLANS
also bought the johnny 5 movie prop thats wooden ,full size and detail
but made from wood and paint and other stuff
I will keep checking on them. I couldn't hope to accomplish something like that. Way beyond my capabilities.
I am currently working on a non-traditional robot. He's going to be a Minion like from Despicable Me.
Oh wait until you see him. It actually looks like one. I used cloth and liquid latex as the outside skin so that he moves with the camera. I'll work on posting my project soon.
I have 2.5 Amp Motor Controller, EZ-Board and MP3 trigger. I would like to figure out a way to wire them all up to say a 12v battery.
Sorry I am semi technical, can follow directions but I am new to electronics in general.
i made a programable wire twister at work
grounds should always to tied at one point like a screw terminal ,thats what called SPG single point gound
also instead of using zip ties,i use spiral wrap tubing,makes it nice and neat
@jstarne twisting wires not always great idea
best always is to seperate the the power wires
@sfoy since you have only a 2.5 amp controller ,you can twist the power wires together and same with MP3 trigger
what 2.5 amp motor controller are you using,second you will need a dc-dc step down circuit
since i dont know if you can build a simple circuit here is one that will work ,12 volt in 7.5 volts out
dc-dc step down converter its about $3.55 from china screw terminals
pretty easy to use 12 volt and then adjust for 7.5 output and 2 amp fuse inline with the battery ,i bought 30 of them ,great dc-dc converters super easy to use and adjust
Now do I need this step down thing because of the voltage of the battery? Would it be easier to use a lower voltage batt?
Sorry newbie
Thank you!
robot.
I have two servos for arms and only one for head. With the design it's really only pan adding tilt didn't work out so well. I wanted to keep it simple for first one.
Also have amp controller and mp3 trigger but that's it.
you only need just the battery pack that comes with EZB
