Great video Steve. Can you please tell me how many AMPs this system pulls? I am very new to electronics. If I had a 24v battery with 10 AMP hours what kind of run time would I get? I am using 24 v motors for the wheels and dome. I am really trying to figure out what battery specs I need and I am struggling. Any help would be awesome! Thanks
Great video! What are the pros/cons of using power output from your motor drivers as power for your Arduino and MP3 trigger, as apposed to a dedicated 5v bus? This is certainly much simpler, but any concerns?
Steve, do you have the same issue with the MEGA ADK Board, the processing chip in the center of the board gets superhot to where I can't even touch it? I'm using 1" stand-offs from the board so air is getting to the card. Should I be concerned! Not sure if this is normal or not. I touched it and left some skin on the chip. All my connections match yours and I'm running 11.9 volts to the Sabertooth and the Siren10, 5 volts to the MEGA ADK and MP3 Trigger Board.
I use the screws that come with the Sabertooth and Syren, other boards are M3 and the spacers I just 3d print using up ends of filament rolls when there's not enough to start a large print, I'll just set off a bunch of spacers
Does the Arduino MEGA ADK have an associated number with it to search on AliExpress? And what issues were you experiencing using the Uno and Shield boards?
I've only really found one supplier of ADK's on Ali so it shouldn't be too hard to find them. I pay around £34 per. The shields have an incorrect chip meaning it won't communicate over USB (ie to the dongle). A fix has been found for this now which involves removing one of the chips and replacing it with a different (ie correct) model number.
Why not use an Arduino Due? It's a bunch faster (84 MHz, 32 bits), and the SAM3X8E has the USB device and host interface native, so you don't have the clumsy communication over SPI.
Primarily because the mega/uno route is mature and part of the original sketch, that way it's easy to support in the community. Once people introduce new boards, it becomes more of a challenge to support them. Of course, there are plenty of other ways of skinning this proverbial cat, I just happen to like this one. Hope that answers the question.

None, I've had zero issues running it this way, and as you point out, it's much simpler.

Not that I’ve noticed, I’ll check later and leave a new comment
What kind of screws/sizes and standoffs are you using to mount the boards?
