After mounting the Circuit correctly works wrong it emits a very annoying beep, after there would be a dispute they do not give me a very bad solution because the components are of very poor quality. The circuit I need and I'm not given any solution
The designer in general is not bad and works. Delivery-20 days to Amur region (it is very fast). Track number tracked all the way (untracked local just loses or... assigns itself). 1 point removed for the absence of holes under the design of the connectors of the minijack (just cut them studs) and the curvature of the body (the hole under the power connector will have to melt). Otherwise there are no problems. Everything works.
P.S. With impulse power supplies there are interference and noise (the signal was sent from the player, not from the computer). I put in a transformer. Perhaps an additional stabilizer would solve the problem with the power from the pulse, but did not bother.
