Been messing around with the Smoker I've made with the ardunio powering the fan.

Mid Thottle - Min smoke,
Move the Throttle a bit and get full smoke,
full throttle - Min smoke.

Might mess about with it so when the engine sound start up. the fan to rev up and down too.

Nice one Tim...

Did you make the smoker unit as well or just bolt on the Arduino control?

Hi C3po.

made the smoker too.

cheers

Tim,

What type of fan did you use and what voltage is it working at?

Did you use PWM to control speed? and was this via some sort of transistor?

Cheers

Hi C3po,

the fan is a CPU 12volt fan (not the pwm version)and running it on 6 volt as 12 was to much and pushed the smoke out too quick. I tied the neg wire via a Mosfet to control the speed. Should of listen to good friend along time ago to with this little mosfets instead of relays(cheers John :) ).
The board moved on a little bit, it now controls not just the fan but also the lights.

now i unstand how to use them, will be using them more often.

Will post pic of the board and video of it in the boat for full effect.

cheers

Show off Tim lol looks good mate you planing on building an old steam powered sub now then ??


Mark.

now there an idea, if you could block the funnels off when under water it might work.

12v fan 6v power supply - Genius - thanks for that nugget - just need to work out why smoke refuses to travel down 3mm pipe.....

Had that issue before. didn't come out that well.

had some luck going from a 22mm pipe and made a funnel to about 3mm and did help
