 ### 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.
