Help
Sebi, i'm looking for a phototransistor with the code BPX 25. It's quite old (1995). I need this component to complete my project, but i just can't get it in my place(Malaysia). Can you teach me how to make a phototansistor by using the normal transistor, just like the way you said. Or, do you know any other phototransistor can replace this? Thanks
