DAC Resistor for FPGA VGA

The real goal for anything that has VGA, DVI or LCD oriented is to be able to display output data to a user in a way that is easy to understand so that they can give some intelligent input by creating a VGA controller that uses a resistor DAC to create 512 unique VGA colors.

Putting Together a Digg Button Kit

The creators thought it might be interesting to inspire the generation of technologists and hobbyists who frequent Digg with a fun and easy project that not only teaches but is a lot of fun. It is a very simple beginner electronics that teaches how to solder and program microcontroller.

Converting Your Arduino Boards to Run 3.3V

When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving replacing the voltage regulator and fuse.

Build a Switch to Kill Switch of your Car

This project teaches us a way on how to protect our vehicle and it seems that a steering wheel lock and an engine kill switch with a good hood lock seems to do the job. Some of many electrical ways to stop a car from starting and to kill switch is one of these systems and to interrupt its operation.

Arduino Based Geiger Shield

This is an Arduino-based Geiger counter shield that is easy to upload data to the internet and also interchange tubes. It is open source and Arduino-based, so it will be easy to hack to other interesting applications.
