Airwick project - Electronic Circuits Projects Diagrams Free

d.hatfield88 · 28th October 2009, 04:42 PM

Hi, I'm an art student and basically what i want to do is alter an Airwick Freshmatic automatic spray.
At the moment the circuit board allows a burst of air freshner every 9, 18 or 36 minutes but what I need is for it to work say every 30 seconds.
This is probably very very basic electronics but I have not got the slightest clue how it might work.

Any help would be very much appreciated
Thanks, Dan

Send a picture of the PCB, I know what product are you talking about but I have no idea of how it looks inside

As far as I'm aware it's micro-controller based, so wouldn't be easy to alter.

My girlfriend put one of those sprayers in my bathroom. I just know it's going to squirt me in the eye someday.

Thanks, Dan

That is a lot of air freshener, what smell are you trying to cover?

ah, micro-controller based? Forget about it, remove the old circuit and put a 555-based one instead

d.hatfield88 · 29th October 2009, 05:35 PM

basically ive altered it so it will spray paint, its for a piece of art that im working on, the fragrances u can get u wouldnt want to spray any more than what u already can lol.
thanks for the suggestions, any idea where i can get one of these 555 things from lol

How to hack an air freshener
The above link shows close-ups of the PCB. Looks like an encapsulated microcontroller amidst other SMT componentry.

Mike2545 · 29th October 2009, 11:42 PM

Why not use a 555 and a solenoid and custom build your device?

HarveyH42 · 31st October 2009, 02:20 AM

Wonder if you could replace the canister with pepper spray... One of little key-chain size looks about the same.

What good is that unless you are very close to it when it sprays? It has to contact your skin and membranes to have any effect.

The active ingredient is oil based, what ever gets sprayed, can transfer the fun stuff to the hands and fingers, and eventually to some unfortunate area of the body, that won't be amused.

D.hatfield, here is everything you need, check the schematic at the bottom of the first page. Obviously, the solenoid should be connected to the relay
