Modern electronics is indispensable for every large model railroad system, and it provides a solution to almost every problem. Although ready-made products are exorbitantly expensive, clever ...
This application note will describe a low-cost microcontroller-based replacement for the mechanical thermostat which eliminates these drawbacks. The PIC10F204, Microchip’s 6-pin PICmicro® ...
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 ...
Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...
