Audio Auto Shutoff I have had many requests to design or provide circuits for graduation projects. Yes, I had to build a graduation project too before receiving my degree. Even though I have always refused to design circuits for this situation, I thought it might be helpful for you to see what I built for my project many years ago when I graduated in 1978. I will also provide a more detailed description of the circuit than I normally do. Hopefully, this may help some of you with your projects.[...]

Control sound automatic by BC109 This circuit is the sound controls automatic circuit, by it will fix to don’t give popularity level in the sound doesn’t expire. When feed sound signal reaches in this circuit , as a result , will have a signal, will the power goes up to flow through LED shine to LDR. The connection and a resister have a side input ,make control popularity level in the sound that a side output get , when see the circuit has already. I uses important equipment , be the transistor number BC109 and other equipment a little again.[...]
