    Thank you for all the kind comments.

    There is a long way to go with this project. It's been complicated with the current "lockdown" as Peter my co-conspirator who is the engineer whizz who has made tech going into the turrets lives 50 miles away. - He has the turrets and superstructure and I have the hull - it's been a little bit frustrating for both of us...

    Therefore the project has been delayed but all will be good in the long run..

    Smoke, flash, synchronised gun and atmospheric sound onboard & shore based plus a few other gems on the hit list - look out for future updates!!

    The rotation and elevation speed is configurable. The kit that is on the test bed is not the kit going in the boat - final calibration will happen with new digital brushless super smooth servos etc

    Hi Graham,

    Great project....

    I scratched the surface of this 3 years ago - but did not progress it very far.

    I was going to "reverse engineer" things a little.

    I intended to move the oars manually to get the shape of the movement whilst connected to the servo's and read/capture the servo position/time electronically which could then in theory be reproduced.

    What controller are you using?

    Are you familiar with the Pololu Maestro Servo Controller range? - would be a doddle using scripts. The Maestro can then be controlled via a serial link from your microcontroller

    https://www.pololu.com/docs/0J40/all#4.c

    Another great video...

    This project came about as I often wondered what the output from a programming card was - could not be any different to the output of a radio receiver which can be used to achieve the same results.

    The other aspect is that they always seem to be difficult to get hold of and expensive...

    With no surprise the output from the card is a sequence of PWM pulses

    It really is so simple to program from the radio tx/rx!

    The HK website states:

    The ESC can be programmed through your radio using the intuitive cycle menu or by using the optional Program Card 9261000059-0. The programable features are:

    โ€ข Running Mode - Forward / Forward & Reverse
    โ€ข Motor direction
    โ€ข Low voltage protection
    โ€ข Start mode (Punch)
    โ€ข Motor timing

    The program card is this one according to HK

    Hi,

    I don't believe you can reprogram the switches. - What would you like to be able to use the switches for?

    Had a quick looks and this is a 6 channel TX - 4 channels taken by the 2 sticks - that leaves 2 channels between 3 switches.

    I would think that you have a 2 and a 3 position switch and the other is a mix/mode/rate selector.

    Looking at the 2 switches these could be used within the boating world but are not proportionally controllable like the 4 channels on the 2 control sticks.

    The best way to get a feel for what the 2 switches & associated channels do is to connect a spare servo and then move the switch.

    Don't give up just yet - it's always difficult typing suggestions when instinctively if the kit was infront of you you would just do things!

    Do you have a servo tester?

    Do a visual check of the 3 pin rc plug on the esc - pins look ok / seated correctly/ haven't pushed themselves out of the back of the plastic plug?

    Just to confirm are you using the throttle channel on the receiver?

    What is the model number of the Spektrum receiver?

    The constant beeping suggests the esc is not seeing a signal from the receiver or not one that it sees as โ€œfullโ€ throttle.

    How did you program the esc that is working - via the radio tx/Rx or the programming card?

    If via the radio use the same Rx slot/channel and check that this channel has not been reversed nor has the output been restricted by the digital trims(end point adjustment)

    May take me a day or so.

    By memory(dangerous!) - make sure fingers are away from any props
    1. Make sure your radio TX throttle channel is not reversed
    2. Turn everything off
    3. Turn on radio transmitter and then receiver
    4. Place throttle is FULL(up) position
    5. Power on esc
    6. You hear dow ray me
    7. You then hear 3 beeps ( beep beep beep)
    8. Possibly another couple of beeps
    9. After about 5 seconds you hear 4 tones - this is programming mode

    10 this is all from my fading memory - I will dig out the real deal and update you

    Let me know if you get any joy

    I have some Turnigy Marine ESC's - I have programmed them from the radio/receiver - I don't have a programming card.

    Let me get them on the desk, re-familiarise myself with process and I will post my findings.

    What exactly do you want to set? fwd/reverse? number of cells?

    I think my previous post may have been confusing - apologies - the Jeti RC controller was simply included to show how a tablet could be supported.

    There is no link between the smart phone / tablet and the radio control transmitter apart from being an ergonomic/useful support platform whilst in use.

    The RC sticks would be used to control the throttle & rudder and the smart phone/tablet to control lights/sound/guns etc along with other accessories in a more intuitive and vastly cheaper way than some of the jab the stick X times or multi channel solutions.

    My main intention was to show what could be achieved for less than the cost of a couple of fancy coffees.

    This was an experiment I did a while back using my iPhone to explore a modern concept of multi function RC control - the current HMS Rodney control concept is a twist on the same theme.

    Hi Doug,

    You are correct the intention of this control method is for ancillary components only (not throttle or rudder).

    The current implementation of RC multi channel control is klunky and old fashioned and just not kept up with what's available today.

    I have got the opportunity to overlay a live video feed on the screen but it's further down the todo list.

    There is virtually no latency with this system, you could use more than one control/slider at any one time - the radio packet payload contains multiple control values in each packet

    I agree too - most of this is well beyond my level of knowledge.

    I have just spent 12 hours working out how to update a parameter - I was 99% of the way there it turns out after 10 minutes but it took another 11.5 hours to find the missing bit.

    That's how this has been written - blood, sweat and tears - and a substantial amount of lost brain cells.

    I am no expert - just a very determined person that is never beaten by technology - oh and Mr.Google helps ๐Ÿ˜Š

    My phrase - "I think it's the way I have learnt most of my stuff - getting very stuck first..." holds true

    Hi Escrich,

    The is no application as such.

    It's simply a web page created using html,css and javascript and resolved in a web browser.

    So not iPad dependant - it could be any wifi/browser enabled device - e.g. other tablets/ smart phones etc - screen resolution would be interesting!

    The radio link is a 459mhz packet radio
