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.

Superprobe is small and low cost multi-uses probe that can be used to measure, test or diagnose you electronics project. This device is designed around a PIC16F870, a 4 digit LED display module and very little else. All Operation in this device is via 2 pushbuttons. This multi tester has 18 function or mode: Logic [...]

This project is built to monitors the instantaneous current, voltage, frequency, and real power consumption in home. To monitor voltage, the project uses a dedicated miniature transformer. Current is measured using a home built current transformer that clamps around the incoming power feed. The current transformers are homemade from split ferrite cores with 100 turns [...]

This network power resetter is built based on PIC16F628 microcontroller. It controls a solid-state-relay that connecting 110VAC Power line with a satellite internet receiver or routers.
