Uh this is what we have decided in the last meeting. But if we use battery
Yeah b uh f well uh I meant uh by by battery I meant uh I will not have a uh a wire between the remote control and the energy source but uh I didn't fou we didn't decide yet which kind of battery we will put inside the the remote. So uh it's a point to discuss. Then uh the case material we have uh uh also several choices , like wood , rubber , titanium or latex.  But uh well it's not a a re uh well a real issue for the   from the technical uh point of view. Concerning the interface uh we can we can put mm just simple buttons or scrolls or buttons uh much more complicated , but it also requires that the chip to process the button is more complicated so.
Mm.
And uh this is the last point , the choice of chips. So what I have f found is that I think basic battery or kinetic uh energy uh collection is the is the better way to provide energy because I think solar energy wi won't work  in a cluttered uh  uh environment.
