And I'll get this one uh in digital uh form too.
'Kay , we're going to um uh talk about working design. Um , the method of the remote control is uh electrical energy , it activates a chip uh in the remote. It's an electrical circuit which compose uh messages in the form of uh uh infrared signals to control the television. Mm , it's a nowadays very uh known , a known uh uh technology. Um , the known technology can make a cost very low. Uh , it's a wild uh  a wide sale uh of uh remote controls in the world. And and the components are very uh very cheap. Um , Uh , diodes , uh bat batteries and uh uh LED lights , they're needed and they're uh everywhere available. Uh , again , it's a fair price. It's a common uh technology uh , like I told um  Uh , the circuit board , it's the most um important uh um part of the remote control. Uh , we can use for that uh fibreglass with copper wires , it's  it is uh  can be made as fast as printing paper. It's uh   it's all very uh
Okay.
Yeah , they're making it uh all the time. Uh ,
