Seeker II is an autonomous mini-sumo robot which is designed to compete in mini-sumo robot competitions. It is low, fast, very aggressive, and has wide tires that provide a lot of traction. The robot's brain is Microchip PIC16F876 programmed in C.The mini sumo robot sensors consist of two range finders and two edge detectors. The range finders are Sharp GP2D12 analog range sensors. They are cheap, simple to interface to, and provide very accurate results without being affected by ambient lighting conditions. The edge detectors are Fairchild QRD-1114 Infrared sensors. ...

The project is used for repairing of broken PC monitors. It can generate video signals with 8 different raster images. The tester features 4 resolutions for each image combination: 640x480x60Hz, 800x600x60Hz, 1024x768x60Hz, and 1280x1024x60Hz. Main component of the project is MCU AVR AtTiny2313 from Atmel running at 20MHz.MCU generates horizontal and vertical sync signals directly from its ports. While resistor network work as simple D/A converter to convert R,G,B signals to analog signal (0~0.7V). This portable tester is powered by battery or DC power supply adapter operation: 7.5V~12V. If you ...

Xoscillo is free oscilloscope software that acquires data using an arduino (with custom firmware) or a Parallax USB Oscilloscope. Aguaviva is developing this project to support more platform.This C#-based application features frequency analysis using FFT, auto detects the hardware, load and save waveforms, zoom in and out, open several waveforms at the same time, and ability to run several oscilloscopes simultaneously. This scope software works on Windows and Linux operating system. Download XOscillo here.

This wireless temperature sensor is developed based on PIC12F675 microcontroller. The project is equipped with DS18B20 1-Wire temperature sensor and Sure TTL Bluetooth Module.The advantage of using Bluetooth than Xbee module is that no custom hardware is required on the receiving end and almost all modern laptops have an integrated Bluetooth chipset, so no more hardware is required on the PC end. Bluetooth Thermometer firmware is written in PICBasic and is compiled using ProtonIDE. You can download firmware, schematic and source code here. PIC Bluetooth Thermometer is designed by Jamie ...
