Because quite a lot of time and effort has gone into the electornics side of this craft I feel I should stick up a page about it.

  

 

Ontop of the standard systems to run the engine I decided I wanted to have a warning stobe, bilge pump, headlights and a tacho (Rev counter), water temp and oil pressure guage.

Trying to figure out how to connect this all together was a real nightmare because I wanted to encorporate fuses into the system for safety and have a series of connectors so I can remove the wiring loom in modules to get to the various parts and to make the engine removal easier.

 

(A general shot of the entire loom laid out)
The dashboard loom
The ignition/fuse/lanyard kill circuit closeup. This is basically the most important bit and allows the engine to run even if the dashboard loom has a fault.

A closeup shot of the fusebox. It is a 6 blade automtive fusebox.

These are a nightmare to setup but they make it easy to unplug bits of the loom. The great thing is that they come in sizes from 2 all the way to 20.

I have drawn out the correct wiring loom on the PC for peoples use. The origional hand drawn one had a couple of errors.

Because I love a challenge I decided to make a "fly by wire" style choke control system using a control knob on the dashboard and an electronic servo at the back of the craft linked to the choke on the engine. I have done this for a couple of reasons but the main one is that I simply wanted to know if it was possible.

This is the schematic I have based my controler on. Its pretty basic but seems to do the job ok in testing.

I drew this schematic out on PCB and ended up with quite a nice small board layout.
I then processed the board and ended up with this:
This is the final board, wrapped with the connectors on it ready to be clipped into the hovercraft.
. Thats pretty much all of the electroniccs I can be bothered to write about...Hope its been fun :-)
