How to Make JIBO Homage : a DIY Music Dance Robot
DIY Power Tool Storage W/ Charging Station
No such thing as too little current for charging a battery. All it will do is trickle charge. But I don’t know if the circuit will allow it, but as long as the voltage is correct, the current will just charge the battery much slower. Instead of an hour at 1A, the peltier generator will take 2 days at .02A, assuming your device doesn’t consume faster than that
There’s literally no way for even a scientist to answer those impossible questions. Solar output? Are you joking? How would he know the intensity of the sun in your location? How long to charge? Depends on how intense the sun is, how realistic that 3400mah rating is, how old that battery is, how much current is flowing, how efficient is your circuit?
Why would you ask that? It's not even remotely similar.
"Concluding from this, these "speakers" are designed to show the capabilities of the printer."Maybe if you did a little reading before being pompous, you wouldn't look like a fool to a stranger years later. "This project was a demonstration of the potential of 3D printers to create high-fidelity, finished products. We wanted to create something that could only be created by means of additive manufacturing. The ultimate goal was to create a functional, consumer-ready piece that took advantage of the strengths of 3D printing."
