Been following BobK's Agincourt build.......what a beast.
Would love to do a large scale Hood or KGV myself so have a slight vested intrest in this.
Will get the old thinking cap on while i am decorating my mother in laws spare room this afternoon.... :-))

Stewart,

It's the only reason I got involved - to stimulate the grey matter - I often find myself turning over a problem in my head seeking a solution whilst doing the mundane things - so I am now off to fit 3 radiators - great joy...

Re the smoke - I know Geoff has come up with a great solution on his build - just seeing if I can get more smoke without loads of batteries...

So far so good but testing in its early stages

Stewart:  it is indeed !   Am I crazy?  Quite probably.  By all be tempted into a giant 1/96 warship.   %%

C-3PO has kindly been giving me technical assistance on controlling turret rotation for all seven turrets.  I will defer to his electronics/Arduino expertise in developing the technology for this.  I believe it will look really amazing on the water, something of a model boating first.  Once operational I am sure others will then want one.

Can I ask how the turrets are to be controlled? Is it going to be as simple as flick a switch and the turrets will dance a tune pre-programmed, then return to home position, of several switches with differing programmes? Or a custom control deck with pots for each turret, turn the pot, the turret turns.


I like the idea of the custom deck..........really got the grey matter going now.

Stewart:  C-3PO's system uses an electronic compass to find due north.  You rotate a knob on your transmitter to set the desired bearing angle, and any guns that can train on it will do so.  The clever bit is when your ship changes course the guns will continue to bear on that target, provided they can train onto it.  Natty  O0

Eight people sat pond-side, seven with their own turret control box, eighth as fire control officer, passing them (electronically) targetting and fire instructions! %%

I don't build warship models but am still very interested in this period of naval history.

I think that the hardware/software solution that has been arrived at for model use is a huge leap forward in achieving realism. Well done!

Now that is one sweet piece of kit.
Going to tag along on this, very very interesting.... :-))

Now that is some serious gear.
Lots of work going into this, doff my cap to you sirs.


Not ventured down the Arduino route, stayed with Picaxe, the language is slightly easier to work with for me anyway.


A normal capital ship with 4 turrets will be slightly easier to manage rather than the 7 on BobK's leviathan.


Are you going to have some sort of valve arrangement on each barrel to simulate firing and then breach opening. It always makes me chuckle when you see these big guns hurl out massive projectiles with a huge bang and a mass of flames and when the breach is opened this whisp of smoke comes out the end of the barrel like in the old westerns with the old six shooters.

Stewart:  Getting 4 or 7 turrets turning, the only difference is in repeating the small electronics board and stepper for each.

The actual gun fire system will be based on Geoff's awesome Iron Duke model.  A small piston pushes a measured quantity of smoke fluid up through a Thermistor heating block inside the turret.  Very effective.  (photo: (c) Martin MBM).



On the actual ship, after firing, compressed air was blown up the barrel, so only a very small amount was visible when opening the breach.
