  1. the voltage will be quite a bit higher than 12Volts when the gates are operating due to the engine running should be around 13.3Volts so the drop shouldnt be too significant.  i'll hook it up this weekend.  there are some heat sinks i could add to them as well if they are getting hot.  i'm going back and forth on the relays b/c i'm not sure where to mount them.  but the enclosed plastic box will already be hot in the summer so the FETs will heat up faster.  

  2. if what you're saying is true about the motors not working well if being extended to the dash of the boat the martin's box that has the motors tie in at his box would be causing people's setups to die earlier.  i understand what you're saying about over heating it - i feel if it melts down i have reason to go get my money back from amazon and change to the relay setup.  b/c the product description was wrong.  if i install these relays you speak of now i have about 40% more wiring to do plus i have to find a place to mount them in my boat ... i'm skeptical of its need. as running both motors doesnt cause any warmth to the FETs under no load even when they are on for 8 seconds.  

    Thanks for you logic its harder to read someone else's and apply it.  but i'll look at in detail tonight.  i tried forever to get the millis function to work properly really wish this was just a PLC and my life would have been much easier. 

  3. I dont think it should be an issue they say they are rated for that and they arent running for long amounts of time - while testing if they ran continuously for over 30 seconds the FETs would get hot to the touch.  but there is never a time these will be running for that long.  i'll watch the draw under load.  not sure why this couldnt be mounted under the dash with this setup either.  i'll watch temp when i test it once the weather warms up. 

  4. Transfer code tested with GPS good to go. only "issue" is the outputs stay high for 2x as long when transferring - not a big deal but just an FYI gates still retract and deploy in about 4 seconds. 

    I'll update the table and the video shortly - 

     

    Also has auto manual logic now 

    Pin 10 when connected to gnd allows you to run just off the switch with no GPS.  

  5. I will post my project as i plan to use an arduino for control - still trying to figure out how to get GPS data into the arduino currently - but i'll post step by step on that.  My larger concern is the physical stuff since i'm a EE the electronics is no problem.  But how to mount the gate how large to make it etc. is where i'm currently struggling
