Arduino Based Ethernet Shield

The device is used for open connection to other internet hosts with the use of Ethernet chip Wiznet W5100 that provides a stack of network IP capable of both TCP and UDP protocol.

Courtesy Light with Time Delay Switch Aspect

The circuit was constructed to provide a time delay feature when switching OFF a light to give the person enough time to reach the bed before the lamp completely turns OFF.

Digital Output from Light Sensor

The project pertains to ISL29020 which converts light input into digital output using high performance light sensor with low-light sensitivity.

Remote Control Receiver Using IR with RS232 Output

The circuit was constructed to produce a remote control by utilizing infrared technology and providing the output through the RS232 interface.

Digital Oscilloscope Based on PICAXE

The device was developed using PICAXE microcontroller as the heart of the digital oscilloscope for troubleshooting, and monitoring the electrical signals in a circuit in detail.

Push Pull Amplifier Using Vacuum Tube

The amplifier project utilizes vacuum tubes on the preamplifier section to produce a push pull output stage while using point-to-point connections.
