Nice project!

Cool project, ive been toying with the idea to make a weather station too.

Sweet project! Where are you getting the trip/odometer readings, from the GPS? If so how accurate have you found it to be? Any videos of it in action?

Just wanted to say how great this project turned out. I have been thinking of doing something similar but never thought the images could ever look as good as you got them to. Nice!

Yep, I can confirm that the D40 has no cable shutter release capability and the IR only works for 15 minutes at a time, then the camera resets itself back to regular shutter mode. I too wanted to build a time lapse circuit for my camera but it doesn't look possible. I guess you could design a mechanical release system using a servo to push the shutter manually.

Well, leaning to do it could be one. smiley  Isn't that what hobbies are all about?  Also, he could be n the situation that me may be able to e-mail the code to them.  This would save having to travel to a specific place to hand out keys.

That depends on how the question is worded. If he said he was doing it to learn as a hobby, then by all means go ahead. However, he made it sound like he was doing it for his job. In that case you have to logically ask whether it makes sense to bother the customers with a custom made machine that may not work when they get there, especially if you could just as easily hand them the keys. I agree about the emailing aspect, that would be cool. Though again, he has to plan to change the code daily and ask himself whether he is secure enough in his job to risk it not working for a customer.

I like the SD card idea though.

You need to be more specific about what you are doing. Are you actually trying to measure if someone has taken a drink lately or is that just an example? How to plan for the project will depend on exactly what you're doing because measuring water consumption in a cup will be quite different than a pond or pool.

I think there are a number of things you'll want to ask yourself or plan for before starting the project. First off, what is the point? If you have to hand the customer a code number to get their key out, why not just hand them the keys? How would the keys be placed back in the mechanism afterwards? What would stop somebody from saving the code so they can get them out over and over again for free? What type of "switches" were you thinking would work to hold the keys?

It sounds like a feasible project though I'm not sure how you'd control the key holding mechanism? I guess you could use servos but then you'd need to figure how to get more pwm channels.

I believe you can use the map function to reverse a set of points like this:
y = map(x, 1, 50, 50, 1);

Thanks! Now the only question remains, do I wire the 5v line to both sides of the chip?
