Hi there,
Two quick disclaimers:
1. I am a newbie, so if I look lost with this post, please direct me to where someone might be able to help me (and apologies)
2. I am a DIYer with some practical know-how, though admittedly I'm enquiring about an off-the-shelf solution to my problem (ideally)
Cool, so the problem I'm seeking help with is that I want to create a small fan which operates intermittently. The fan should ideally run for a few seconds every hour or so. The timing is not critical, but should be around this: if it ran for a few seconds every few hours, that would be ok too. It only needs to control a tiny fan, an inch or two diameter. And if it could run off 9V or lower, with the ability to run for a good while (i.e. months) then that would be great.
The application of this bizare set of criteria is that I want to fit a compact fan into my cigar humidor (within a custom build cedar box). It would help regulate the humidity evenly around all the cigars so that there are not microclimates of high and low humidity. Cigars should ideally be kept around 65-70%RH, but I have noticed through scrupulous measurements that the humidity pools at the bottom of the humidor, leaving the top somewhat drier and the bottom noticably wetter (running the risk of mould forming). The humidor is only about 500 cubic inches in volume, hence the need for only a small fan to disturb the air inside and for only a brief period of time.
So, in short, I'm wondering if anyone can help by suggesting an off-the-shelf circuit which I could programme/adjust to the timings about (on for a few seconds every hour), which I could put between a fan and a battery. I'd be confident about following a kit, soldering, and so on, but maybe not so much building anything from scratch.
Left-field solutions also welcome. I.e. solutions which are perhaps not premised on a circuit inbetween a battery and a fan.
The help would be SOOOO much appreciated, I just don't know anyone who specialises in this sort of thing. If you are in Melbourne, Australia, I will buy you a beer.
Cheers,
Paul.
P.S. I should also add that I have trawled the net for many hours trying to figure out what it is I need, but I have been a bit bamboozled by some of the terminology and technicalities. I'm not just trying here as a first resort for an easy fix, this is my last resort!
