A simple oscillator can be used to generate negative voltage from a positive voltage. It is useful for LCDs that lack an internal voltage inverter.
This circuit, a 74HC14 hex Schmitt trigger inverter is used as a square wave oscillator to drive a small signal transistor in class C amplifier.
I use a 12V 20W halogen lamp (MR16) and a 4. 2Ah SLA battery for my bike light system. The battery has only limited life at this power rating, so I designe

This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This high-brightness version draws an average of 16 mA and has a typical sensing range up to approximately 24 inches (60 cm).
This schematic is version of a simple 10 LED chaser. There is no 555 timer used because at my local electronics store they are over $4 Cdn. Instead, an oscillator made up of two sections of a 4011 NAND gate is employed.This chip is very inexpensive and extremely common.
