um because its uh not so expensive. And there are uh a lot of uh wires , uh which um connect the components in it , the battery , and there are um switches and things like that. There's a lot of small uh electronics. So it won't be um uh too expensive to build it. Only twelve Euro fifty I think uh we will make it. Now   And here I have the top of the remote control. Uh here's some kind of chip. Uh on top of this , there are uh the numbers. Uh you have all on your remote control. And uh the teletext uh button. And uh here's the battery. And when you push the button , it will uh will be sent to the chip. And the chip will um send it to all kind of sub-components. That's what I said , it's very difficult.
And after that it will be sent to the infrared. And that will send it to your television. That's a short h uh how it works. Uh I think I can uh make it uh difficult , but we all  we all don't get it. My preferences ? It's uh  it won't be uh  We shouldn't make it too big. Uh also for the cost , uh we should only put one battery on it. A long-lasting battery. Uh also for the cost , uh use only plastic. Not other materials. Also because of the cost , uh not too much buttons on it. We can also make uh a button uh with a   menu uh button. And then um that that you will see it on the T_V_. And on the T_V_ you can uh switch into the menu.
Mm-hmm.
That's  I think it's easier. And the bleep signal , y uh you told us. Uh but we can also use it uh a bleep like something , when the battery's empty , then there is a bleep. Then you'll have to change it in a in a week or something. And also the bleep , when  what I told you about uh when you lost it , and you push a button , and then you hear bleep bleep , and we will find it. This is uh just uh
