hahaha that's a fantastic little project. It seems like it'll be fun, too, but if you're an electronics newbie I might suggest that you go for a much simpler project. This isn't because I don't think you can put the circuit together, but I just don't think a newbie would understand why they are putting all the sensors, capacitors, etc into the circuit in the first place. For instance, can you explain why there is a 0.1uF capacitor going into some of the pins of the RF detector chip? Does it matter if it's 0.1uF or 0.2?
My point is that finding a circuit online and just putting it together will give you experience assembling the circuit, but you'll still be stuck when you have another project that you'll need to do the design for but won't understand how.
How about this: put that idea on the backburner and return to it once you're more familiar with electronics (
throughout this entire post, I've assumed you have very little familiarity, so if anything I'm saying is wrong, just ignore me :-P )
Make a simpler project first. Electronic dice might be fun, but I'd suggest something that will help you to make this eventual project work. What about this: see that LED circuit there? Why not make it and attach it to a potentiometer, and see if you can get it to light up the LEDs like you'd expect it to. This would mean you'd get to learn HOW the LM3914 chip works and, by extension, how to read/find datasheets for the given chips. Once you do this, then you can PROBABLY move into the full circuit (without any vibration yet, just replicate what's already been done), since by that point you'll understand a bit more about what's going on.
Once that's done, it's time to learn which of the outputs of the AD8313 produces the intensity, and then how to wire that into a motor (I'll give you a hint: it's probably not a good idea to just dump the voltage into a motor! You'll need to design a way to turn that voltage into a useful motor signal...I'm totally not going to tell you how to do it yet
You'll have to try on your own)
Of course, if you DO jump right into that circuit, it'll be a pretty big challenge but will still be valuable experience.
**EDIT: Oh, and that part about all components being SMT is not good for a beginner. You want "DIP". "SMT" is Surface Mount Technology, and it's the SUPER small little chips that they use a machine (or a REALLY good hand solderer) to put onto boards. "DIP" is "Dual Inline Pin", and it's the more familiar "computer chip" that you'll be able to find. It's much easier to solder/work with DIP than it is to do with SMT unless you happen to want to get it printed by a professional company.
