Greetings. I just order my Raspberry Pi and have not even received it yet. But it has already ignited my imagination. What do I do with it once I get it?
I can program in C and have found other languages kind of easy to pick up because of that lower level programming, but I know nothing about robotics. So, I want to start out small. Here are the ideas I have that I think I could do. I want your feed back.
1. Super bedroom clock with sound sensor. The idea is that the clock could be programmed not just for time but for days of the week too, whole calendars. The alarm would be more in line with growing light and bird sounds and not beeps. Also, we have neighbors below us who work late and can be loud late at night. So, my idea is to set up a sound sensor that listens to the dB of ambient sounds, and if they reach a threshold, white noise kicks in to cancel it. Actually I think there is some kind of pulse pink noise that is more conductive to sleep, but I will have to research that. Other sea and storm sounds could also be added. Is this doable?
2. Fan with thermostat . This is the simplest, but might be a good place to begin. But it does build toward my next somewhat disturbing art project which comes next. It seems straight forward to me. A thermistor measures the temperature. If it reaches say 80F the fan kicks on. The art would be to put the fan inside of a Greek god looking head that is blowing on you.
3. An arm holding a fan that - fans you. Like above, once the temperature reaches a certain level, a motorized arm kicks in and simply rotates the arm up and down. When it reaches the bottom, it switches and moves back up. It is holding a simple Oriental fan or even a palm frond. The arm is shrouded in a latex skin that makes it look like a human arm. So, you are sitting on the couch and it starts getting warm, when your slave boy robot arm (is that politically incorrect when taking about simple robotics?) starts fanning you. What kind of motor would you need for that? Is a simple DC motor with some kind of mechanical clutch best. Or a directional stepper motor or something else? How easy is this art project?
