I have obtained two Silent Radio LED signs on Ebay and I intend on rebuilding them. To get one of them apart I had to reach through a hole in the back and cut the wires to the power transformer. To remove the logic board I had to use pliers on the screw head and pliers on the mounting shaft. In one case the screw broke off rather than come out. Tin sheers or heavy duty wire cutters can be used to remove the connectors between the sign and the logic board.

This is well documented AVR based GPS tracker project. AVR microcontroller talks to GPS module and records location data that can be later played along with aping program like Google Earth.


By following build instructions, you’ll be able to interface a GPS module via three wires. Also there is a good explanation how to integrate stored location data with map software and see your track visually.

Simon game is very simple. Player has to repeat sequence of played flashed LEDs. The more deep you go, the more complex it gets. Building Simon game is very easy. Using microcontroller you basically need four LEDs and four buttons to go.

Simoninns from instructables have build a micro version of Simon game. The board is only a 1.5 inch square. It is powered by PIC12F683 microcontroller which also generates a sound via QMX-05 speaker. Game is powered with CR2032 battery what makes game small and portable.

Hello Readers

Time for something different  - a single button combination lock. Allow me to explain…

Normally a combination lock would require the entry of a series of unique numbers in order to unlock something or start an action. For example:

Arduino board and Ethernet shield can serve as basic web server. With limited Arduino resources you can run simple web pages where you can send variable data and also read them back to Arduino. This is convenient when you want to have convenient control panel and remote access.

So following project actually is a simple demonstration how to enter couple text strings via web page and display them on LCD attached to Arduino. Code can serve as a good starting point for more complex projects.
