GSM SIM emulator using PIC Microcontroller

Here’s a project from EHobbyProjects which demonstrates their hack for emulating a GSM SIM card using a microcontroller, EEPROM and SIM card adapter. Their instructions include reading the IMSI and KI data from the original SIM, and then using their Configurator program and hex programming files in conjunction with a PIC16F877 and 24C64 EEPROM to […]

Anger detector using PIC16F877

Technobits presents notes on a developing student project designed to detect the anger level of an individual based on their pulse. The idea behind the project is to detect pulse levels and then display user feedback messages on an LCD readout. Elevated pulse = anger, slower pulse=calm. (References in the notes regarding blood pressure are […]
