Circuit Lake

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: 640×480×60Hz, 800×600×60Hz, 1024×768×60Hz, and 1280×1024×60Hz. Main component of the project is MCU AVR AtTiny2313 from Atmel running at 20MHz.

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, [...]

IR Widget is PIC12F629-based project that able to captures infrared signals from remote controls. It allow you to determine the carrier frequency and demodulate the carrier in the digital or analog domain. The captured information can be used to view, recognize or reproduce the signal. The hardware is simple and low cost.

This project shows you how to construct a PCB drill machine driven by a master-controller board and three stepper motor driver boards. These four single sided PC boards each contain an Atmega16/32 microcontroller. Communication between the boards is performed using the RS485 protocol with all communication initiated by the master-controller. The PCB drill machine firmware [...]
