Wireless Chat Known as ChatBot

The ChatBot project is a set of wireless chatting terminals that use 128x64 graphics LCD and Ericsson Mobile keyboards.

AIR GPS Device Based on Arduino

The project will be used as a portable air monitoring device for exploring the neighborhood and urban environments for fossil fuel burning hotspots and pollution.

RFID Card Reader with PIC Applied

The project utilizes a PIC16F628A with an on-chip comparator in order to feed the output from the op-amp directly into the PIC and extract the digital signal from an RFID card reader.

RF Transmitter with 2 Channels

The transmitter project provides 2 channels for transmitting and receiving which operates on the 418MHz frequency.

Decoder Device for RBDS and RDS FM Tuner

The decoder project was created to support FM tuners from both USA using RBDS and Europe using RDS at 88-108MHz band.

Homemade Wireless Network Detector

Sensing the presence and relative signal strength of wireless hotspots is made possible by building this small electronic wireless network detector project while having a feature of portability.
