hi robo rad and dave

did you try to camera cable turn 180 ?

i Think cam cable only fits one way. It is possible that the Roomba voltage too high for cam but there is a built in V regulator at camera port and EZB is rated for 16 volts, Just never run HDD servos while on Roomba power(14v).

I am trying to ARC program arm clockwise and counter clockwise rotation with old analog motors not servos only 6v.Also using some heavy duty 4-30 volt single motor drivers that not really supported by Ezb4.So using the custom movement panel,script blocky for forward command button. It works but no matter how many different scripts I make, the motor driver will not shut off last movement and then whole Ezb must be turn off reset before it will work again...Weird problem to have. Motor controller only has 3 inputs to connect on EZb digital ports,direction,PWM,Ground. Motor only has A, B connection. Direction pin is 0 or 1 for clockwise,counterclockwise,Yes I know servos would be way more easy but I like a good challengeI am thinking to go back to my 8 channel relay board for analog motors, much more easy and precise tuning with timing.

I'm a little lost as to where you are at, What controllers you're using and what troubles you are having. I would try just attaching one servo to a digital port at at time to your EZB (IoTiny?). Unplug everything else from the EZB and use new servo cables and try basic moves to different points. Then try a different digital port. Then add your servo board and a servo and test. Try with a couple known working servos. At least this way you will see where your problems starts.

Be carful when you plug and unplug cables to the ports on EZB. It's possible to crack a pin's solder joint on the board if you are too ruff. If you do this you could have a poor connection, intermittent connection or no connection at all.

Hdd servos for head movements are working great,Running mainly with a 7.4 battery now. The arms have the old fashion original wrist motors,analog magnet 6v motors.Very hard to control with the Cytron 4-30 v single driver board, will work perfectly with a mechanical relay board, easy to program with Arc. Adding relay board to Cylon back pack area,will look great there.:)

Now I am getting somewhere! Relay board took only minutes to wire up, like 2 minutes to program the 1 digital port needed,the timing is so easy to control this old magnet motor,just as easy as servo! Only need 2 relays for each arm giving me 6 more for lights or airsoft gun or any other 6 volt motors lying around!No more resetting problems!

"By your command"!

Right on Dave, watching the classic series gets me inspired!and I really don't know why I took a year break from robot building, Doing it now is just too much fun during our lockdowns here.Even movie theaters are closed again here! Anyway one of the coolest ever Battlestar Galactica moments in history was actually 1 episode of Galactica 1980 Return of Starbuck. He assembles broke crashed Cylon, as it comes alive...We- are - enemies! No we are not!
