This project allows you to read many common EPROM and Flash memory chips. It’s equipped with USB interface that uses FTDI USB to serial chip. The PIC18F4550 microcontroller firmware handles the various differences of the range of EPROM chips. The project only uses HyperTerminal PC software to control and read the chips. Intel hex [...]
This Laser Range Finder (LRF) is a low-cost distance measuring instrument that uses laser technology to calculate the distance to a targeted object. It can measure up to 8 feet away but for optimal measurement the range is about 6 inches to 4 feet. The project is designed by Joe Grand.
This Automatic Packet Reporting System (APRS) Weather Station project built based on PIC16F877. It comes with humidity sensor (Honeywell HIH-3610), Pressure sensor (Motorola MPXA4115), thermo meter (DS1621), RTC (For time Stamp) with battery back-up. The project uses 4×20 LCD to display all weather parameters, but you can still operate it without LCD for power saving.
The aim of this ATmega644-based project is to build a portable device implementing wireless technology and taking full advantage of the wide-spreading Internet to provide a convenient solution to monitor human health.
