I have been looking at all sorts of alternative smoking devices and have now come to a system that I think will work for me. I purchased a vaping device which I felt would be a self-contained unit , easily charge easily replenished and would work for a long enough period for a day’s sailing. The system comprises of :-
1 An ecig devise - Smok Stick V8 Kit
2 A water pump –Dosing Pump Mini Peristaltic Self-Priming
3 An air pump DC 5V 6V Mini 370 Motor Air Pump Vacuum Pump Self-Priming
The e cig required some modification in that I needed it to work by a simple switch action that could be incorporated in an electronic circuit rather than the push button on the side of the unit. So I decided to dismantle the unit with some help from You tube the end caps are a push fit in the end of the tube and they are a tight fit. The guy in the video attacks the unit with a rather large hammer, I took a more gentile approach and mounted it in the lathe collects and gently wiggled it loose. This seems simple but it took an hour to release it. Having got the internals out I could see the on/off switch which was part of a circuit board and had tiny soldered joints. Using the multi-meter I determined the terminals that switched on/off and using a big, big, magnifying glass and a modified soldering iron tip I was able to attach two wires. I drilled a small hole in the base and fed the wires through then refitted the end caps, the unit can now be operated either by the button or just connecting the two wires.
I now need an electronic devise to switch the components on/off at varying periods, this is where my electronics expertise comes in – “call a friend” Graham93 Warrant Officer another member on the site had offered to help me out so I gave him details of my requirements which was :-
An E cig device which requires switching on/off pulsed at 3 sec on and 3 seconds off this also needs, at the same time to switch the water pump & air pump on/off at 1sec before the ecig and stay on for 4 Sec and off at the same time. However Graham said he could make the timings’ variable which meant that with experiments I could make the devise work to optimum safety and look realistic. The starting point for timings was:-
See table (table wouldn't reproduce in the text Pic 3)
The device was delivered after a week and it also came with a two page instruction manual, so I wasted no time in testing it, albeit out of the boat and it worked perfectly, at this point I didn’t have the final pump unit. So I then started to fit all the parts into the boat which will let me try it in the bath!
Many thanks to Graham for his contribution to this smoker, It has really performed well.
