Status

August/Sept 2016:  Updated HW seems to last now, but SW issues exposed.  I do need help programming.  If any one is interested/capable in programming Arduino - please let me know!   My GPS parsing routine crashes pretty regularly...   


What is SteadyPass?

 

Low cost boat speed control system with enough functionality to give you flawless wakeboarding experience without heavy investment.


 

Why?

 

Because I have a 1999 Bayliner for my wakeboarding hobby, and nearly no one can keep speed constant while watching out for river traffic, so that I myself can enjoy the wake. But like many of you - I'm not ready to spend $1k+ on a gadget.

 

Is it available to purchase?

Yes as Board + LCD kit.  Plan to set up kitting process later in 2016.

Is it a competitor or replacement for PP and RS?

No.  Eric and Justin have put serious effort in developing their respective systems as tournament level speed control . Including patent US5700171 by Eric P.Horton from 1997 describing throttle linkage. Both PP and RS invested heavily in productising, have custom stamped/molded parts contributing to the looks. By all means, if you have sufficient $$ - do purchase one of them.   Recommend RS.  But if you are feeling like DIYer - please watch for updates in BLOG section.

 

 

Kit goals and features:

 

Kit may come as assembled head unit in 3.5" gauge of my choice/availability, but you can submit backgroung image/logo.

Or - Assemble into your old speedo case yourself – customize with your text or picture behind the glass! 

Requires power and RPM hookup from tachometer input.  Can also accept paddle wheel (not sure it's needed yet) and temperature sensors  

Speed measured and set with 0.1mph accuracy, target dialed in with knob. 

Modular design for standalone (in a box) or speedometer casing installation. 

DIY approach, with off-the-shelf components, guarantees prolonged serviceability and upgradeability. 

  1. Flexible architecture – additional parameters can be  displayed on same screen (any analog sensor can be adapted) 
  2. Replaces speedometer and clock on your dash. 
  3. Night backlight for any-time usability.
  4. GPS speed.   
  5. RPM input from tach wire (ground coil wire or 5v square)
  6. RC Servo-based Actuator with PWM input: direct mount or bowden cable remote
