Time Switch Controller with DCF Update

Creating an automatic control for mains heating for the house is the objective of the project which uses a PIC-controlled time switch that gets its time updated trough the DCF77 radio signal.

Homemade Chassis for LM3886 Power Amplifier

The project is designed around dimensions where a LM3886 chip amplifier kit is tightly packed in a simple chassis the uses four aluminum panels and two heatsinks.

LM4780 Audio Power Amplifier Project

The power amplifier project obtained its A4 name due to the four separate power amplifiers contained in this unit which offers great flexibility using different modes of operation.

Hi-Fi MOSFET Amplifier with 100W Output

The project was built around the Hitachi lateral power MOSFETs to create high fidelity Class AB amplifier.

Smallest USB Analyzer with Low Speed

The project is termed as Atapchi which refers to a small fruit in Singapore since the device is probably the world’s smallest low-speed USB analyzer.

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.
