We added the updated datasheet of the clap switch kit

As I notice a lot of people get confused when they try to build their own schematic. The complexicity in the power input is one of the major problems for the usb power input.So i decide to design a more friendly schematic for those who want to use a 12 power supply only directly.So have a look at this.

We have just released the new clap switch kit with new schematics and pcb layouts.The new kit is based on the lm358 opamp and 4013 flip-flop...

The following programs calculate the relevant currents and voltages for various switch mode power supplies and display these graphically. Furthermore the programs give suggestions for appropriate choking coils and high frequency transformers.

I've changed the values of the resistors R11 , R12 , R6.
This is for the amplification level of the signal.
I think that the previous values offered bigger amplification than we wanted.
So now we have more flexibility with the audio levels of the signal.
New values: R6 =10K , R11=4,7K , R12=10K
