The Electronic Mini-Badge is a PIC24FJ64GA004-based electronic badge that displays color slideshows. Many electronic badges display scrolling text using a matrix of discrete LEDs. This low-power system features a graphical OLED display and can be easily upgraded to handle animation, video, or RF communication. [source]

The Electric Vehicle (EV) Inverter project is a starting point for engineers trying to convert a vehicle with a gas engine to one with an electric motor. The innovative inverter was built using a control board and software based on Microchip Technology’s MC-1 development board. It features a dsPIC30F6010A and three dual IGBT modules with gate driver boards. The finished system can power a wide range of AC induction motors. [source]

The MiniTron is a high-end vacuum tube stereo amplifier with efficiency, distortion, and power output controlled by a dsPIC30F2023. The innovative system features three main subsystems: a vacuum tube amplifier, a DSP controller, and a high-voltage switching power supply. The fully functional amplifier successfully blends its unique circuitry and specialized processing software to precisely match the radically different worlds of high-voltage analog and low-voltage microcontrollers. [source]

LCR meters used to be relegated only to professional design labs. Not any more. This portable LCR meter makes it easy for you to analyze the analog performance of virtually any device under test, whether in your lab or on the job. The dsPIC30F4012-based meter uses DDS techniques and DSP methods to condition the resulting voltage and current signals. Its handy user interface and graphic LCD make it easy to operate and read. [source]

Unlike old-school mechanical alarm clocks that you have to set manually, this Internet-connected alarm clock provides three primary features: automatic time setting on power-up, streaming MP3 music, and remote management. The easy-to-use, PIC24FJ64-based clock is connected to an ENC28J60 Ethernet chip, an MP3 decoder chip for streaming music, an organic LED graphical display, and a 24LC512 EEPROM for storing alarm data, fonts, and images. [source]

Variable-speed drives for AC induction motors are readily available on the market. But what if you need one for a single-phase motor that operates in the 2-HP range? This innovative controller is the solution. Designed for use with a capacitor-start/capacitor-run motor, it includes active power factor correction (PFC) and inrush current limiting. The motor drive hardware is built around a dsPIC30F2020 DSC. The drive communicates via an optoisolated serial port to a PIC16F687-based interface unit. [source]
