Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

The occasion for this project was retrofitting an illuminated wall picture with LED backlighting. As soon as I applied LED power, the brightness blinded me — much brighter than the original T20 ...

This is a circuit in which LED glows slowly in the beginning, then grows brighter and once again slowly it becomes dim. The basis of the whole circuit is an operational amplifier IC named LM358. This ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...

1. A Cree XM-L RGBW high-power LED can be driven by two LT3964 LED drivers for accurate 1:8192 per channel dimming. 2. Typical driver architectures offer 8-bit color resolution. Implementing a driver ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

The concept: find a COTS* motorcycle LED light dimmer that can be spliced into an auxiliary LED light array to vary the light output. We found this “Rotary LED Dimmer”, made by ADVmonster and designed ...
