The Arduino led pov clock circuit has been an interesting project, and the author has made use of the arduino feeding system with the popular wireless energy transmission method, which is an additional circuit for additional NE555. But if you do not want to deal with the wireless power supply for the Arduino Pro Mini, you can use the battery at the input of the 3.3v regulator (AMS1117-3.3) used at the inlet of the wireless energy circuit making it a bit troublesome coil winding can be troublesome

Stick Mixer Circuit
The Stick Mixer, to stick to Melody and Bass entered the first stage operational amplifiers, amplify each twice, the second operational amplifiers in the mix. Third step is the second mixer circuit inverted signal back to a positive phase. Mixing process, given the non-inverting amplification Low Cost first stage is to TL072, 2 second to third step is to use the NJM5532. This op amp is TL072, NJM4558, NJM4580, NJM5532, NE5532 in comparison to the audition decided.
