Don't know if this is the best place to post this but I have a custom made Unicron head that I want to add sound effects to. I'd like to have the clips triggered by motion but if that's not feasible a push button will do. Can someone recommend a device capable of that? I'd like it to be small so it can be hidden inside the head and capable of recording (or uploading) & playing back 3-5 10-15 second clips. I tried to look something like that up but didn't really come up with what I'm looking for exactly. Any help is appreciated.
