Here is a circuit of a simple servo tester. It's easy to build and is useful for testing servos or anything else that can be plugged into a servo socket of your receiver - R/C switch, ESC, RefAnt's counter(!) etc.U1 is a 555 timer IC, U2 is a 74HC04 (or 74HCT04, 74HC14, 74HCT14), U3 is a 7805 5V regulator (a 78L05 would be OK). Resistors are all 1/4W, 5%. Capacitors C2 and C3 should be 10% tolerance. You MUST use a linear pot'! 74HCT04
