Blinks, but also makes square waves. ### Blinks, but also makes square waves.
A great candiate for a soldering workshop becuase it is gratifying with the blinking LEDs. There is more. It creates a square wave that can be observed with an oscilloscope. Also, even if sinus waves are preferred for producing radio frequency (RF), the project is a very good entry point into exploring oscillators, a corner stone in generating RF.

### Components
Q1 and Q2 are the BC547 transitor. Alternatilvy the equivalent 2N2222A can be used, it has slightly more gain than the BC547. However, the 2N2222A will have to be mounted rotated 180 degrees as it's pin out is the other way round than that of the BC547. Q1 and Q2 are the BC547 transitor.
