www.microchip.com This reference design provides an easy method to evaluate the power, and features of SMPS dsPIC® Digital Signal Controllers for high wattage AC - DC conversion application. Discover the many benefits of digital power control implementation in this reference design. The SMPS AC - DC Reference Design unit works with universal input voltage range, and produces multiple DC outputs. The design is based on a modular structure, which features three major power stages; the input stage, intermediate stage and the third stage, a Point of Load. The input stage is a PFC Boost Converter, the intermediate stage is a Phase-Shifted Zero Voltage Transition (ZVT) Converter, which includes ZVT Full Bridge Converter and Synchronous Rectification, and the third stage is Single-phase and Multi-phase Buck Converters. This reference design uses two dsPIC33F16GS504 devices; one used for the PFC Boost Converter and ZVT Full Bridge Converter, while the other dsPIC® DSC is used for Single-phase and Multi-phase Buck Converters.

Programmable DC-CDI using Atmel 89c2051, - max 55mJ@6000 spark energy - programmable curve, rpm limiter - firmware written by manoosos as a cut down version of his original Moto Guzzi v7 Digital TCI ignition firmware. Works fine, needs some more filtering due to a noisy voltage regulator.

This is my own diy clock, it's a plan how to build it up. If you have any questions, ask me, maybe I can help. The clock build up in 3 main sections, the 1 hertz source, the number motors, and the 4073 ic-s. It use for restart 10 seconds, and 10 minutes if they reach 6. If the clock reached 24 hour, it must be also restart. With 2 integrated circuit you can generate correct 1 herzt sign. The 4060 make 2 hertz with the oscillating circuit, and the 4013 flipflop divide it with 2. And here you get the one hertz sign. Here is the schematic, as you can see. For display numbers, the circuit use 4026. When it get an input, the number which show, will change 1 higher. And when it reach 10, send an input for the next 4026. So the clock count the 1 hertz signs from the oscillator. You must set the correct time, so the circuit have 2 buttons, one for minutes, and one for hours. If you push down set minutes, you send a 2 hertz signal from 4060 to minutes display 4026. The power supply is 5 volt, made with 7805 voltage regulator.

Digital Voltage Selector www.jakeselectronics.net I wanted to write a program for a 16F84A to be able to select different voltages by the press of a button. How it works, Each time the button is pressed the PIC scrolls through output pins (putting them high, one at a time. I'm using 3 pins) Each pin is connected to a transistor. When selected, the appropriate transistor pulls a resistor into play, with the reference pin of the LM317 (variable voltage regulator) and in turn changes the output voltage. At the same time as scrolling through the 3 different outputs (or simply setting one of the 3 output pins high, the chip tells the LCD to display the set voltage. (In the video the LED's up the top of the board are simply showing which pin is high, RB5,RB6 or RB7)
