Hacks and Mods: LED Light Box

Lighting Circuits Diagram | By: Diagram mania

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 […]

LED Clock Using PIC (Microcontroller)

Lighting Circuits Diagram | By: Diagram mania

Now you can always know the exact time. With this design you can have an atomic clock in your room. Isn’t that great? Read on to know more. First of all, it is not about any radioactive elements here. This is about building a clock display that can get the time from the DCFF77 facilities […]

Hacks and Mods: Incredibly Illuminated Persistence of Vision LED Clock

Lighting Circuits Diagram | By: Diagram mania

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 […]

Temperature-Controlled Switch

Lighting Circuits Diagram | By: Diagram mania

It sounds rather mysterious: a switch that is controlled by its ambient temperature. All without the touch of a human hand, except for when you’re building this sort of electronic thermostat. There are a lot of handy uses for a thermally controlled switch. If the temperature inside your PC gets too high sometimes, the circuit […]

Touch Sensitive Light Dimmer

Lighting Circuits Diagram | By: Diagram mania

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

Lighting Circuits Diagram | By: Diagram mania

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 […]

Multicolor HD LED

Lighting Circuits Diagram | By: Diagram mania

Most PC enclosures provide only a single LED to indicate hard disk access, with the LED being connected to the motherboard via a two-pin connector. However, this LED only works with IDE drives, and if a SCSI disk controller is fitted, its activity will not be visibly noticeable. This small circuit remedies that problem using […]
