This forum is about interaction & contribution so others can help you to improve it.
But I don't know if they are able to do it if they know the basic schematic. *laugh*

hello.
so you don't know?
ok let me tell you some thing Funfinder.
if they are able to do it, they are able to do it, and if they are not able to do it, they can't .
if you don't know ,you will not change any thing in such situation .
so one last thing that left to us is you want put them in a situation of bigeeners.yes , no confidance with bigeeners we don't know if they can do it or not.
I want ask you a question. Can you do it if you know the basic schematic . for me , you are a part from "they".

NE555 is reversed.
The top left should be pin 1.
Pin 4 and 8 must be connected together.
The 100k trimpot cannot be connected in series to the Tx coil.......
