Overview: The solar tracking device is designed to ensure that a flat panel with a solar cell is constantly aligned with the movement of the sun across the sky. It utilizes two light dependent resistors (LDRs) positioned on opposite sides of a fin to measure the light levels. By comparing the readings from the LDRs, […]

When it comes to debugging a microcontroller circuit, there aren’t a lot of simple options. Since a microcontroller circuit might have multiple things going on at the same time, measuring voltages with a DMM isn’t an option. Using an computerized In-Circuit-Debugger solution is expensive and elaborate, and time-consuming to set up. People often resort to […]
Wise Clock 3 is an open-source, highly hackable geeky clock that shows a lot more than the time. Its main function is to display user-editable quotations retrieved from an SD card (like those used in photo cameras). In addition, Wise Clock 3 can show the time in “Pong” mode or “Pacman” mode. It can also […]
