dbrayton1 Posted November 30, 2014 Report Share Posted November 30, 2014 (edited) Most of what's in these posts are out of date, but provide an interesting look into the process of prototyping an AVR based control system. The final commercial product will ultimately look and function differently than the prototypes. Thus, please don't rely on anything here when it comes to a buying decision. This all started as a frustrated surfer/boat owner's DIY project and grew from there when I met Ryan, who happened to need a control system for GoSurfAssist. Thanks to everyone for their input and support. Edited September 1, 2015 by dbrayton1 dobber, Greeko, MidnightMax and 3 others 6 Quote Link to comment Share on other sites More sharing options...
WakeDirt Posted November 30, 2014 Report Share Posted November 30, 2014 What kind of boat are you trying first? Yours? An f22? Quote Link to comment Share on other sites More sharing options...
oldsmobiledriver Posted November 30, 2014 Report Share Posted November 30, 2014 How does/will it tie into the different models of zero off? What year boat has a different model of zero off? Quote Link to comment Share on other sites More sharing options...
dbrayton1 Posted November 30, 2014 Author Report Share Posted November 30, 2014 What kind of boat are you trying first? Yours? An f22? Of course ;-) The test boat provided by Texas MasterCraft is also a F22. However, my part, the controller, is designed to work on any boat that uses two lenco tabs/gates.

dbrayton1 Posted November 30, 2014 Author Report Share Posted November 30, 2014 How does/will it tie into the different models of zero off? What year boat has a different model of zero off? Too many variables so I've included a GPS chipset and antenna in my design to guarantee it works properly without any integration headaches. oldsmobiledriver 1 Quote Link to comment Share on other sites More sharing options...

Smokinjo Posted December 1, 2014 Report Share Posted December 1, 2014 You may want to look up martinarcher on the malibu crew website. He has developed this already along with GPS chipset. Designed to work with gates and lenco actuators. Open at certain speed as well as retract. Also the ability to switch sides.

MidnightMax Posted December 1, 2014 Report Share Posted December 1, 2014 The other cool thing Martinarcher has developed is a waterproof wrist band remote control allowing the rider control of the gates when doing switch crossovers. Glad to see more DIY innovation Dbrayton!! Anxious to see how yours progresses Quote Link to comment Share on other sites More sharing options...

MidnightMax Posted December 1, 2014 Report Share Posted December 1, 2014 Yes it sounds like it. I thought I read somewhere he's getting $1 to $1.5 k for his set up Quote Link to comment Share on other sites More sharing options...
Smokinjo Posted December 1, 2014 Report Share Posted December 1, 2014 He does sell them and is very helpful in set up from what I hear. Not sure on the cost though. Quote Link to comment Share on other sites More sharing options...

dbrayton1 Posted December 2, 2014 Author Report Share Posted December 2, 2014 I connected with Martinarcher and learned a lot about his controller. It's really amazing the amount of work he put into it. He went all out. I don't envision doing something with a display and all of the other features he offers. It definitely looks like a great option for anyone looking for the absolute best aftermarket option. I talked to a lot of folks that use the more complex systems on MasterCraft, Nautique, etc.. and the feedback was that they wish they had something that didn't require reading instructions, doesn't need a display, and "just worked". Also looking at what's available from Lenco at the other end of the spectrum, I am aiming for the gap between what is extremely rudimentary from them and the higher-end from Martinarcher. The videos below show the basic premise of the design: one-click for surf left, right, or reset. I've added a simple dial to fine-tune the wake, but it could easily stay at the 100% mark for most people. The GPS retracts the tabs above 14 mph. There is a lot more to the logic, but that's the gist of it. First Test of Basic Actuator Automation http://youtu.be/LGx-5dXtQ9E Update to Include Manual Fine Tune http://youtu.be/2vHSKjjkecA Please don't hesitate to post suggestions, wishes, likes, dislikes, etc... Now is the time to chime in and influence the design, or convince me I'm waisting my time ;-) Also, anyone interested in a simple (no GPS, basic up and down) alternative to the Lenco box and switches? Software for that is done. I just need to finalize physical design if there is interest. Quote Link to comment Share on other sites More sharing options...
Smokinjo Posted December 3, 2014 Report Share Posted December 3, 2014 That simple design you have in mind is similar to what I have in my Axis A24. Switch stays in the middle when not active, then it's either surf left or surf right or quick switch based on the driver switching the switch from one side to the other. Really simple as you describe. That's the best thing I like about it. What your working on is a great solution for those that want to add goose flappers to their boat. oldsmobiledriver and MidnightMax 2 Quote Link to comment Share on other sites More sharing options...
Greeko Posted December 3, 2014 Report Share Posted December 3, 2014 Have you set up a PWM reading circuit to display actual position of the lenco actuators? Quote Link to comment Share on other sites More sharing options...

Greeko Posted December 4, 2014 Report Share Posted December 4, 2014 ...or if in testing I realize I need it. Currently using other techniques to maintain positional awareness. You could use Pin 6 or 7 with a pwm reading function.. I think its called PulseIn to determine the actuator position. I was toying with making a really simple pwm reader but when I tested something i HAD to retract the actuator to 0 or home position for it to work properly. oldsmobiledriver 1 Quote Link to comment Share on other sites More sharing options...

dbrayton1 Posted December 4, 2014 Author Report Share Posted December 4, 2014 Thanks to Mark (my neighbor, friend, and really good coder) we are almost ready with the software to hook up to the tabs and start testing. The final remaining task beyond the unknown unknowns on the software side is to complete the GPS input/logic. Also, I'm ordering more hardware for the first real beta physical build this week - including a few pie in the sky options that may or may not pan out in roughly six weeks, or not ;-) Stay tuned... http://youtu.be/o_aerXaALhk MidnightMax, Greeko, oldsmobiledriver and 2 others 5 Quote Link to comment Share on other sites More sharing options...
dbrayton1 Posted December 5, 2014 Author Report Share Posted December 5, 2014 Anyone have opinions on if and when you would want surf tabs to automatically retract? Keeping in mind most autoretract scenarios might require you to hit the surf button again before starting. Quote Link to comment Share on other sites More sharing options...
Shawndoggy Posted December 5, 2014 Report Share Posted December 5, 2014 I'm not saying it's the "right" way, but Malibu's system does autoretract and auto deploy. Could you have "surf system on" where it always auto retracts and autodeploys? The Donfather and MidnightMax 2 Quote Link to comment Share on other sites More sharing options...
Smokinjo Posted December 5, 2014 Report Share Posted December 5, 2014 Deploy 8 mph and retract if speed increases over 14 mph. Also retract when throttle back to N before turning to pick up rider. My opinion only oldsmobiledriver, MidnightMax and Kalamazoo 3 Quote Link to comment Share on other sites More sharing options...
dbrayton1 Posted December 5, 2014 Author Report Share Posted December 5, 2014 I'm not saying it's the "right" way, but Malibu's system does autoretract and auto deploy. Could you have "surf system on" where it always auto retracts and autodeploys? Thanks, that's on the list of potential scenarios. I was hoping to avoid that much unnecessary movement to keep the logic a little cleaner and the hardware more affordable for rev1. Something like: System doesn't do anything when engine isn't running Start engine Push surf-left or right, system drops a tab (or deploys flapper) Surf Rider falls Reduce to idle speed Then ? Leave it alone for another set or retract? If retract, it would either require hitting the surf button again, or writing more lines of code to remember where we were surfing. More code = more complexity = potentially less reliable and/or more expensive controller hardware. Then when done, right now you have to hit the middle (done/reset) button to get it to reset to all up. In thinking about the auto-retract when switched power is off like the lenco controller, I'm concerned about safety. It may not be safe to retract a flapper or huge surf tab (vs a small trim tab) automatically in the event someone is near the platform when the driver kills the engine. For me that is a fairly common occurrence. e.g., Driver pulls up, goes to neutral, I grab the handle by the platform or rope, then driver kills the engine and I climb in. For me, I would rather risk bumping the tab than it closing on me. Thoughts? Quote Link to comment Share on other sites More sharing options...
dbrayton1 Posted December 5, 2014 Author Report Share Posted December 5, 2014 Also, keep in mind this controller is more of an alternative to doing it almost entirely manually with a Lenco system vs. something for a similar price that automates the experience a bit better. Replicating what Malibu, MC, Nautique are doing costs a lot more and has been done already by Martinarcher. His controller is over $1k. Hence me trying to find something in the middle. So, where is the "deal-breaker" line for you guys? Right now the only auto retract is >14mph. Could you live with that? If not, where else would you see auto-retract as more of a must rather than a nice to have? Quote Link to comment Share on other sites More sharing options...
