I am an electronics guy...I work for a cable testing laboratory where I perform 90% of all electrical test and 100% of all of the testing that is considered high voltage. I design and build control systems for the machines that pull, twist, and break cables. I also work for a small nano brewery where I have designed and installed a glycol cooling system for the fermentation process. Beer is just a hobby but it is very rewarding to see the brewery grow from a garage home brew to a real busines... Read More »

    Yes...I had a mega board so I tried that first. I noticed on the mega it has two pins dedicated to the SCL and SCA lines from the MPU-6050. I think that would fix it but I'm running out of time. Micro center near me sells a third party UNO for $6.00. It was quicker and cheaper to run down and buy it and try that. It worked and all is good. I would like to try and get the Mega to work but only if I have the time. Thank you

    Update...We are up and running or at least it is bench tested. I changed the board to an UNO and it now functions as expected. Thank You!! Thank you!! for your advice on this project. I will post pictures tomorrow of the final build with one of us riding it.

    I have rewired according to your wiring diagram. the only exception is a 12v relay that turns on the 24v power. I have a condition that when I turn on the power and activate the deadman the motors run at 100%. I was wondering about if I may have damaged the gyro when I had all of my shorts and the floating ground. I have a red LED active on the board so I think I can safely assume at least part of the board is active. do you know if there is supposed to be any flashing lights on the gyro?thanks,Jon

    Ok. I have some problems. I reverted all wiring back to the way it is in your wiring diagram. I have an issue with when I pres the dead man it goes full speed and tipping the Gyro does nothing to control it. any ideas of where to look?

    ihart, I am using the Arduino mega because that is what I had on hand, I was doing some research on the MPU-6050 gyro and noticed in a couple articles that the mega has dedicated input pins for the SCA and SCL. Have you seen or heard any issues with not using those pins and using the same call outs for the UNO? I am tempted to go out and buy an UNO and just try that. thanks for you help, I really do appreciate it.

    Yes I see what your saying. The Arduino recommended supply voltage is 7-12v with a max of 30v. The use of over 12v will cause the Arduino Voltage regulator to over heat. Arduino claims anything below 6v supply causes the arduino to become unstable. This is the reason I elected to power externally from the front 2.1mm plug. My issue was the use of the ground where ,on your schematic blue wire connects second battery, it is floating. by switching it to the other battery all grounds tie back to one point.I think its great to talk about these issues her since we all can learn from each other...it's cheaper to learn from other mistakes! lolultimately what I was originally trying to accomplish was to use a latching switch on the handle bar to remotely turn on the system through a relay.

In that picture is the 2x12 is just hanging and it is bad but the ground path is still good. so I figured I couldn't kill it any more and it was a good candidate for a test!

    Dimension Engineering has been awesome!!! They have warranted the motor controllers each and every time! What I did was I had 2 batteries in series and wanted to use both a 12v circuit as well as a 24v circuit. The problem came into play when I used the wrong battery for the 12v, it is a critical mistake! the negative side of the battery receiving the 12v from the other will give you 12v but it is a floating ground that has a different potential. only because I used its 12v to power the Arduino and it uses that ground as a reference it received the full 24v across the Atmel chip on the 2x12 letting the magic smoke out! the reason I was trying to power the Arduino in that method is it becomes unstable with any voltage less than 6v and the Sabertooth only puts out 5v.

The other issue I saw was that it was feeding an output on the Arduino in the schematic. I will absolutely share my results when it is finished. I am working with a group of students from Itt-tech and we chose this as our capstone project. that is where we looked at your build and thought we could improve upon it. Thanks,Jon

    Here is a picture of the project box wiring after I got it straitened out!
