This inverter 12V DC to 240V DC can be used to power electric razors, stroboscopes and flash tubes, and small fluorescent lamps from a 12 volt car battery. In contrast to the usual feedback oscillator type of inverter, the oscillator of this inverter is separate from the output stage, which allows easy adjustment of the… Read More »

This sine wave to square wave converter circuit is expected to provide good square waves changing a sine wave delivered from an existing generator. Its primary feature consists in the fact that no power-source is required: in this manner it can be simply connected between a sine wave generator and the device under test. The… Read More »
Automatic Emergency Light Project. When mains is absent, relay RL2 is in deenergised state, feeding battery supply to inverter section via its N/C contacts and switch S1. The inverter section comprises IC2 (NE555) which is used in stable mode to produce sharp pulses at the rate of 50 Hz for driving the MOSFETs. The output… Read More »
This circuit applies a CD4049 Hex inverter, which consists of six inverting units, only two are being used in this circuit, so the others are disabled by connecting their inputs to the positive voltage source and leaving the output disconnected. This layout also uses various pins than the original schematic diagram for aesthetic purposes, the… Read More »
This is an unique water level indicator circuit which use 7 segment LED display to show the current water level in the water tank. Most water level indicator circuits for water tanks are based upon the number of LEDs that glow to indicate the current level of water in the water tank / container. This… Read More »
ADC0808 – Simple Analoque to Digital Converter This is a very simple analoque to digital converter circuit based on 8-bit analog-to-digital converter ADC0808. Typically analogue-to-digital converter (A/D Converter / ADC) requires interfacing through a microprocessor to convert analogue information into digital format. This needs extra hardware and appropriate software, resulting in more complexity and hence… Read More »
Automatic Switching-on Emergency Light The schematic diagram shown right here is the automatic switching-on emergency light circuit which is controlled using IC. The most important capabilities of this circuit are: automatic switching-on of the light on main power failure and battery charger with overcharge protection. When mains electrical power is absent, relay RL2 is in… Read More »
This tube sound fuzz mods circuit is taken from the book of Electronic Projects for Musicians by Craig Andertons. This circuit applies a CD4049 Hex inverter, which consists of six inverting units. Only two are being used in this circuit, so the others are disabled by connecting their inputs to the positive voltage source and… Read More »
