2 more kits are in test-hands, to be instaled with linear servo.   If installation works out - I can say we have a recepie for Bowden-Linear setup.  Not the cheapest, but more reliable.

Just powered on my new higher efficiency (less heat) power circuits. Still some testing to do, but seems to work.

Clearly not in time for start of season, but by mid-summer plan to have couple dozen kits available

Meanwhile - enjoy SteadyPass in white


Improving looks or the rear side of unit

not final, but getting there.

Here is progress over past 7 months

Decided to clean it up all the way before offering kits.  Yes, taking longer than Ihoped.  But that is why I am offering BOARD with all guts separetely now.  

First proto of servo kit!!

First proto kit.  
Now need to try it with some one.  My Mercruiser has a weired carb setup, unlike 99% other.  

Assuming 3D printer bracket holds against the heat - this is easy to kit up and offer!

My "Product Marketing" message:


Phase 1 of product is about to start:


BOARD ONLY OFFERING:

Board kit is offered at earlier stage, and is aimed as DIY kit, to be custom-integrated by end user.

Kit components: 

  • Main board with GPS

    • GPS antenna header

    • USB connector for FW update or logging

    • LCD and Encoder headers.

    • 8-pin signal/servo connector or direct solder footprint

    • Separate power lead wire

  • GPS antenna

  • Solderable 8-pin aviation connector

  • Encoder with cable/connector (plugs into board)

  • One of 3 LCD options: 

    • 1.8” – 42mmx21mm viewable area, polarized, white backlit

    • 2.2” – 48x24mm  viewable area, fits in 3.5” gauge, white backlit

    • 3.1” – 71x35mm viewable area, no backlight.

    • Other SPI-interfaced LCDs possibly could be supported

  • Optional: 3D printed LCD holder – please ask

Board specifications:  

  • 7 to 24 volt DC power supply.

  • 6v 4A power regulator onboard for servo.

  • Supercap RTC backup – immediate GPS startup within 3 hours of power down.

  • Two digital temperature sensors input.

  • RPM input: negative coil lead or square 5v.

For $50 extra per order – I can customize mounts/size of board to fit your application.

Kit price:  $200



You will need:


  • Servo

  • Servo mount

  • Cables

  • Assemble board into casing of your choice

  • Assemble signal/servo cable

Back to the project!

Back to the project. I am at the stage where it takes me most time to do less skilled work - integration. With this in mind I wonder - how many DIYers out there would rather purchase control board with display at about $200 and do custom integration?

 

Have next revision of board powered up. It integrates power supply and signal normalization for external components - LCD, enconder, servo, and had GPS chip soldered on reverse side.  Aviation style connector for power, servo, temp sensor, RPM.    Supercap instead of battery for RTC backup. 

One other modification i need - reset button, for a forced FW update, needed in some cases.



Just posting to let know project is not forgotten

Getting close to finish line with home remodel, starting to unblock access to my garage-based development lab:)  Still full of steam to have units available. New boards and new connectors received and are waiting to be worked on. Plan to restart active work in April

Great progress ............ with kitchen...

Had to take some time off-project to work on kitchen remodel. Got to keep my wife happy!!  Aren't we all?

Meanwhile parts for new design concept are en route - should have pictures in march.



Stability improved

Finally had time to re-architect code, to remove couple questionable while-loops.

Unit has been on for more than 24 hours with no reset (long small font number on screen is time in seconds). 

I'm happy, consider issue fixed!

rev 16.50



another piece of puzzle

Those who got early units couldn't not notice a battery hanging from the rear.  That battery is a very nice to have - it helps GPS to start up within couple seconds, vs 30ish.   But it only lasts a year, so need way to replace it.    While I was planning to have unit completely enclosed, to protect from ESD and such - battery access is not trivial.

Just tested supercap backup toay instead of battery.  After re-evaluating usage model - I realized I only need about an hour of backup time, not a year.  That is meant to cover for between the runs, when  engine is shutdown.  But no one will notice longer first gps startup at the beginning of the way, it will be much less than engine warmup anyway.  So about 0.5F cap should do it.


With that change done, and with new connector - I will be finally proud of the looks of the unit from the rear, not only front. So expect some pictures!
