I've been wanting to know how the technology works inside these finger-drums. I would appreciate it if someone could explain to me the type of touch-sensitive technology it uses. plus if you have any examples (pics) that show close resemblance of the circuit boards used for these finger-drums, that'd be much appreciated! below are links to the product I'm talking about:
1. What type of touch-sensitive technology / circuit does it use?
2. How does the wiring look like inside? (example of pics would be great!)
3. Would it be expensive / easy to make? (DIY)
4. Last but not least, I basically want to know how the insides work from the circuit board, to the wiring, to how much voltage it uses etc.
The touch sensitive technology is probably a pushbutton.
The wiring inside will include a microcontroller and a speaker. It runs on 3 AAA batteries -- 4.5 volts. If you have some electronics and microcontroller experience is would probably not be that hard to build, otherwise you will have a lot to learn.
I doubt if you will find anone who has actually taken one of those things apart to give you the exact circuit it uses.
He's not hitting it that hard phoenox. Probably simple capacitive based sensors, the IC's for those are cheap nowdays. The second one may use a simple mat type push sensor. My steps-son has a drum t-shirt that's a thin mat you press on to trigger the drums.
Ya, capacitive touch sense IC's are pretty cheap now. I've used qprox ones. Probably not as cheap as rolling your own, but a lot easier for us who aren't analog guru's.
