So here are some of the electronic goodies I returned with, aside that is from normal building materials like plasticard and rod, the two prop shafts, some propellors etc etc.
I'll work around clockwise from top left.
1. This I have shown before, this is a lighting circuit bought from a builder in Germany, it should have gone in the POSH Venture, but I held it back for this model. It allows the simulation of real lighting via led's, ie, fluorescent tubes, metal halide and sodium. So you can have a flickering light as though a fluoro tube was failing, the flare of a sodium light and then the slow dim and finally out of metal halide types.
2 Two linear stepper motors and next to them their drivers, these are to open and close the stern hangar doors.
3 Motor shield for the arduino, this is to connect various low consumption motors to the Arduino's, less than 1 amp draw on each motor.
4 Seen before, this is an Arduino Uno, this will carry out all on board functions like operating the hangar doors, lowering the fast rescue rib, radar etc etc.
5 Obviously a 4 relay board to connect to the Uno for higher power demands
6 Across the bottom and seen previously, the 5 brushless motors to drive the tunnel and azimuth thrusters along with micro computer fans to help circulate air around them.
7 Eight relay board same as the one above
8 Arduino Mega, this will be doing all the motor control work of the brushless motors.
9 In the centre, most of these electronics are needed to allow this unit to function, this is the Inertial Movement Unit. It detects yaw, sway, forward, backward and up down movement from a set point. This is the heart of the dynamic positioning system I hope to get working, and the Arduino Mega is the brain that interprets the data it sends and turns them into motor signals for the brushless motors to keep the boat 'on station'
What I haven't shown here are the 5 esc's for the brushless motors and also the main drive units. I'm undecided whether to go full brushless for everything or use the brushed motors I had already bought - time will tell
So that is all for now. Hopefully I'll have the prop shaft in and the tunnel thrusters built for the next update, if so the hull will also be in paint!
