Hello everybody ! I'm beginning on Arduino (actually, I've discovered it 2 years ago and abandonned it because I didn't have any cool project in mind), I have 2 Arduinos UNO and 1 mega. I'm not in electronics but I'm a system and web developer.
I will maybe have a baby cat next week, and as we sometimes go to the countryside, we're a little scarred of escapes. I know I can buy something on the market, but... I like DIY stuffs, I like coding, and I would like to build it myself. So, here is what I was thinking about: - Arduino micro or arduino nano or a smaller clone (actually, I only know arduino in the self-made C/C++ electronic world) - GPS/GSM module (like this one to only send position by SMS) or GPS/GPRS module (like this one to eventually send the position to a server) or even a GSM/GPRS module (telit modules are capable of giving an approximative location using the GSM cells), or why not, a GSM/GPRS AND a GPS modules separated. - Small LiPo battery capable of powering the system at least during 5 days without being charged, and if possible, at least 1 week if I design the system to use power only few times a day unless receiving a command by SMS for example. I think at least for the arduino to "know" the clock and power-on the modules when needed, it will be constantly draining power... Unless there is ideas. - Of course, the system MUST use the least energy possible (to have a longer battery-life), MUST be light (if the cat wants to remove it because it's 10Kg around his neck, it's becoming useless) and MUST NOT irradiate the animal (a cat can last ~15 years, I don't want to cause it cancer or whatever, if possible.) - I'm surfing on the level 0 concerning electronics and I can learn quickly. I know U=R.I, but I don't know how to use a capacitor for instance.
For the radiation, if it's not technically possible to avoir dangerous level of exposition, it will have its collar only when we're in the countryside for example, few days every 2 months.
If you have some ideas for me about the hardwares or the project, just tell me. If you explain me a little why you suggest me X or Y module or hardware, I will look for it to understand the use of a component. Thank you for your help.
= EDIT = I'm an open-source lover, everything will be open-source (Certainly Github/Max13), as soon as the project(s) is working and I figure out how to draw the connection between the components.
