Hacks and Mods: LED Light Box

For beginners, it is their first project that gives them a boost. And in order to get that, it is always necessary to make sure that the project that you select is really useful. One such project is the RGB light fader. This is quite simple and can be done easily by a beginner. Read […]


Temperature Candle Using LED

LED based projects require a lot of skill and hence only experienced circuit designers try out these circuits. But there are also a few circuits in this genre that can be done by amateur electronic hobbyists. The temperature candle is one such circuit. Read on to know more about this. The hardware components that are […]


Hacks and Mods: Incredibly Illuminated Persistence of Vision LED Clock

Persistence of Vision flashes LEDs during sure moments as it spins, to illustrate formulating a clock above. The PCB blades have been spun around regulating a pc cooling air blower to create this POV clock. The existence outcome is interjection to bright LEDs that have been synchronized with a Hall Effect sensor. The house gets […]


Touch Sensitive Light Dimmer

With IC SLB0586A from Siemens you can build a simple touch light dimmer circuit that will allow you to adjust the lamp intensity. Together with a TIC206D triac, it enables smooth regulation of light intensity from a bulb of 10W – 400W. A coil of 100µH/5A is required to suppress switching noise. The voltage supply […]


Eight LEDs Make a 100-Division Voltmeter

The circuit in this Design Idea makes a voltmeter that reads to 0.99V. The idea uses a counter IC to drive two sets of four LEDs (Figure 1). Each of these two sets represents a BCD (binary-coded-decimal) value. With all of the LEDs off, the voltmeter reads 0V. With all of the LEDs on, the […]


LED Volt Meter

Here is a Simple LED Volt meter to Monitor the charge level in Lead Acid Battery or Tubular battery. The terminal voltage of the battery is indicated through a four level LED indicators. The nominal terminal voltage of a Lead Acid battery is 13.8 volts and that of a Tubular battery is 14.8 volts when […]


220V AC Powered Blinking LED

I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of the circuit is extraordinarily simple. The capacitor charges by the diode and the resistor. When the voltage on the […]


The Brightest White LED’s On Earth

US manufacturer Lumileds Lighting has developed a whole new breed of LEDs – they use new technology, they look quite different and they produce more light than we have ever previously seen coming from a LED. The new LEDs are branded Luxeon. The manufacturer’s publicity suggests that the Luxeon LEDs are the start of a […]


LED Mood Light

Introduction: This circuit makes a nice lamp that consumes little power, runs cool, and has an incredibly long lifetime. The lamp puts out a warm yellow shade of light, the color may be adjusted by changing the number of red or green LED strings. Specifications: Operating Voltage: 12V DC Operating Current: 80ma approx. Theory: The […]


LED Lighting For Dual-Filament Lamps

Before we describe how it’s done, note that we recommend that the result be checked as having sufficient brightness for a stop & tail-light application. That’s because the light output may be inadequate, depending on the tail-light lens and reflector assembly – so use any modified lamps with discretion! As shown, an additional diode (D1) […]
